About combinational circuits and sequential circuits
Where to Find Combinational Circuits and Sequential Circuits Suppliers?
China remains a central hub for integrated circuit (IC) manufacturing, with key supplier clusters concentrated in Shenzhen and surrounding Guangdong regions. These areas host vertically integrated electronics supply chains, enabling rapid prototyping and scalable production of digital logic components such as combinational and sequential circuits. The proximity of semiconductor packaging facilities, PCB assembly lines, and component distributors within 30–50km radii supports efficient order fulfillment and just-in-time sourcing.
Suppliers in this ecosystem specialize in both standard and application-specific ICs, including multiplexers, flip-flops, counters, and shift registers—core building blocks of combinational and sequential logic systems. With monthly online revenues exceeding US $1.3 million from a single supplier, the market demonstrates strong commercial activity. Lead times typically range from 7–15 days for sample orders and 20–30 days for bulk shipments, supported by established logistics networks offering global air and sea freight options.
How to Choose Combinational Circuits and Sequential Circuits Suppliers?
Selecting reliable suppliers requires systematic evaluation across technical, operational, and transactional dimensions:
Quality Assurance & Compliance
While formal certifications like ISO 9001 or RoHS are not explicitly stated in available data, buyers should verify compliance through third-party testing reports and material declarations. Prioritize suppliers demonstrating consistent on-time delivery rates above 90% and documented reorder rates, which indicate customer satisfaction and product reliability.
Production and Technical Capability
Assess supplier capacity based on product diversity and specialization:
- Presence of dedicated IC listings across multiple categories (e.g., Power Management, Microcontrollers, Data Acquisition)
- Offerings spanning legacy and new-generation chips suggest inventory freshness and technical adaptability
- Customization capabilities in packaging, labeling, and design indicate flexible production infrastructure
Cross-reference response times (target ≤4 hours) and reorder rates (up to 50%) as indirect indicators of service efficiency and scalability.
Procurement Safeguards
Utilize secure payment mechanisms such as escrow services where applicable. Request sample testing to validate electrical parameters against datasheets before scaling procurement. Confirm minimum order quantities (MOQs), which commonly start at 1 piece, allowing low-risk evaluation of component quality and supplier responsiveness.
What Are the Best Combinational Circuits and Sequential Circuits Suppliers?
| Company Name | Location | Main Product Focus | Online Revenue | On-Time Delivery | Avg. Response | Reorder Rate | Customization Options |
|---|---|---|---|---|---|---|---|
| Shenzhen Wanxinwei Technology Co., Ltd. | Shenzhen, CN | General Logic ICs, Multiplexers | US $840,000+ | 100% | ≤4h | 30% | Yes (color, size, logo, packaging) |
| Shenzhen Pengying Electronics Co., Ltd. | Shenzhen, CN | Communication ICs, QFP Packages | US $50,000+ | 100% | ≤1h | 26% | No |
| GOODVIEW GLOBAL LIMITED | Shenzhen, CN | Power Management, Data Acquisition, FPGA | US $1,300,000+ | 92% | ≤3h | 39% | No |
| Shenzhen Dahongxing Electronics Co., Ltd. | Shenzhen, CN | Original ICs, Diodes, Transistors | US $200,000+ | 93% | ≤2h | 25% | Yes (material, graphic, label) |
| Shenzhen Fujiang Electronics Co., Ltd. | Shenzhen, CN | Data Acquisition, ADCs, PMICs | US $2,000+ | 75% | ≤4h | 50% | No |
Performance Analysis
GOODVIEW GLOBAL LIMITED leads in revenue volume and product breadth, with over 400,000 listings in "Other ICs" and significant offerings in microcontrollers and FPGAs—critical for complex sequential circuit designs. Shenzhen Pengying Electronics excels in responsiveness (≤1h average reply time) and perfect on-time delivery, making it suitable for time-sensitive procurement. Shenzhen Wanxinwei and Dahongxing offer customization, beneficial for private-label integration or specialized packaging requirements. Notably, Shenzhen Fujiang Electronics reports a high 50% reorder rate despite lower revenue, suggesting strong niche performance or loyal client base, though its 75% on-time delivery raises potential risk for critical timelines.
FAQs
How to verify combinational and sequential circuit supplier reliability?
Evaluate on-time delivery history, reorder rates, and response speed as proxies for operational stability. Request sample components for electrical validation against manufacturer datasheets. For high-volume contracts, conduct virtual audits of inventory management and quality control processes.
What is the typical MOQ and pricing range?
Minimum order quantities commonly start at 1 piece, facilitating small-batch testing. Unit prices vary significantly by type: basic logic ICs range from $0.04 to $1.00, while advanced signal processing or data acquisition ICs can exceed $88 per unit. Bulk discounts may apply for orders exceeding 100 pieces.
Can suppliers provide customized IC packaging or branding?
Yes, select suppliers such as Shenzhen Wanxinwei and Shenzhen Dahongxing offer customization in color, size, logo, labeling, and packaging materials—enabling OEM integration and brand differentiation.
Do these suppliers support global shipping?
All listed suppliers operate internationally, with standard shipping via air freight (7–10 days) or sea freight for consolidated orders. Confirm Incoterms (e.g., FOB, CIF) during negotiation to clarify responsibility for customs clearance and insurance.
How to initiate a sample request?
Contact suppliers directly with part numbers and technical specifications. Most allow single-unit purchases for evaluation. Allow 7–15 days for dispatch, depending on stock availability. Retain documentation for compliance traceability in regulated applications.
