A connector cross-reference is a shortlist for engineering review, not proof that two products can mate safely or fit the same assembly. When an original connector is discontinued, identify the complete mating system before sourcing alternatives. Housings, contacts, headers, seals and tooling may each have separate ordering codes.
Establish the original configuration
TE Connectivity's LP6.2 application specification documents a connector system through its header, housing, terminal and wire requirements. The example shows why reviewing an application specification is more useful than comparing housing photographs or nominal pitch alone.
Record the original manufacturer, full part numbers, drawing revisions and mating component. Confirm the lifecycle notice applies to those exact items. If the original code is unknown, gather dimensions, markings and the assembled harness details, but keep any identification provisional until the drawing and application requirements agree.
Compare mating, termination and electrical conditions
Check contact geometry, keying, polarization, latch position and insertion depth. Review PCB footprint, mounting features and clearance around the assembly. Do not assume that a housing from another brand can mate with the existing header merely because pitch and position count match.
For crimp systems, compare conductor size, insulation diameter, contact material, plating and retention. Identify the specified tooling and inspection criteria. Include seals and secondary locks where used. Electrical ratings must be assessed under the applicable wire, temperature and loading conditions rather than treated as universal values printed beside the series name.
Approve the assembly and service process
Decide whether the project can replace both mating halves or must retain an installed counterpart. Replacing the pair can simplify compatibility management, but it still requires board or harness validation. Record any changes to assembly instructions, crimp tooling, cable routing or field-service parts.
Test mating fit, retention and contact continuity using representative production assemblies. Evaluate temperature rise and environmental performance according to the product's requirements. Inspect the termination process and keep the approved drawings, tooling settings and sample results with the alternate-parts record. Physical fit is only one stage of approval.
Frequently asked questions
Does an identical pitch establish connector compatibility?
No. Contact shape, latch geometry, housing dimensions, plating and termination details can differ.
Can old contacts be reused in a replacement housing?
Only when the manufacturer explicitly supports that contact and housing combination. Similar appearance does not establish retention or electrical performance.
