Terminals
DF57-2628SCF(41), DF57-2830SCF and DF57-3234SCF equivalents, with tin-plated surfaces
Selection
Match circuit count, mating interface, housing dimensions, conductor size, crimping requirements and electrical ratings to the existing assembly
Replacement Check
Verify the 1.20 mm pitch, 3-circuit configuration, mating interface, mounting clearance, terminal compatibility and operating temperature before production use
Alternative Qualification & Second-Source Support
Part Number & Configuration Matching - Verify circuit count, pitch, housing, locking structure and terminal combination against the existing BOM.
Engineering Review - Compare mating interface, dimensions, wire/crimp requirements and electrical ratings before sampling.
Sample Qualification - Supply samples for dimensional inspection, mating tests, harness assembly and application-level evaluation.
Production Transition - Support repeat sourcing after customer engineering and quality approval, helping maintain configuration consistency across production orders.
Supply, Packaging & Logistics
1,000 pcs per model; samples are available for evaluation.
7–15 working days for standard orders.
Protective PE bags and export cartons; crimp terminals can be supplied in reel packaging where applicable.
Express, air and sea freight, with FOB, CIF and DDP terms supported.
FAQ
Q: Can this alternative connector be added to an existing approved BOM?
A: Yes. The buyer can complete its internal engineering and supplier-approval process before adding the alternative model to an approved BOM or AVL. The required documentation and qualification criteria can be aligned with the buyer's existing procedures.
Q: Will changing to an alternative connector require a PCB redesign?
A: Not necessarily. If the alternative maintains the required mating interface and mechanical configuration, a PCB redesign may not be required. The buyer's engineering team should verify the relevant mechanical and assembly dimensions before approving the change.
Q: Can you support customers who need a second source for supply-risk management?
A: Yes. The alternative can be evaluated as part of a dual-source or second-source strategy, allowing buyers to reduce dependence on a single connector supplier while maintaining the required product configuration.
Q: Can the alternative be qualified without changing the existing wire harness?
A: This depends on the existing terminal and wire configuration. The mating connector, terminal interface and crimped wire assembly should be evaluated together rather than qualifying the housing independently.
Q: What documents are normally required during supplier qualification?
A: Typical qualification may include product specifications, technical drawings, material information, inspection records and sample evaluation results. The exact document package can be prepared according to the buyer's engineering and quality requirements.
Q: Can the same connector specification be maintained across repeat production orders?
A: Yes. Once the model and configuration have been approved, repeat orders can be produced against the agreed specification. Any change affecting the approved configuration should be reviewed before implementation.
Q: How can buyers control connector changes during an ongoing production program?
A: A controlled change process should be used for model, material, tooling or terminal-related changes. Buyers can define notification and approval requirements so that production changes do not occur without the required engineering review.
Q: Can the supplier support supplier audits or quality assessments?
A: Supplier qualification requirements can be reviewed in advance, including manufacturing, inspection and quality-control requirements. On-site or customer-defined supplier assessments can be discussed according to the purchasing program.
Q: Is this alternative suitable for long-term production rather than only sample replacement?
A: Yes. The product can be sourced for ongoing production programs. For long-term projects, buyers should confirm forecast quantities, ordering frequency and configuration requirements so supply planning can be established accordingly.
Q: What should procurement teams confirm before placing a replacement connector order?
A: Procurement should confirm the approved alternative model, circuit configuration, terminal combination, required quantity, delivery schedule and any customer-specific qualification requirements. Engineering approval should be completed before the alternative is released for production purchasing.
