Engineering Selection Recommendations

Primary Recommendation: 68683-325LF This Amphenol ICC (FCI) Dubox™ connector is the most direct substitute. It maintains 50-position configuration, 0.100" pitch, gold mating contact finish, 1000V rating, and through-hole solder termination. Active product status with RoHS compliance ensures long-term availability and regulatory alignment. Operating temperature range of -65°C to 125°C exceeds the original specification.

Secondary Recommendation: 76342-325LF Amphenol ICC (FCI) Dubox™ alternative with identical position count, pitch, and gold contact finish. Active status with RoHS compliance. Mated stacking height of 11.04mm is specified. Insulation material is thermoplastic glass-filled rather than polyphenylene sulfide.

Alternative for RoHS3 Compliance: 2-215307-5 TE Connectivity AMPMODU HV-100 series receptacle with 50 positions at 0.100" pitch and gold mating contacts. RoHS3 compliant. Termination includes kinked pin and solder options. Operating temperature range not specified in available data.

Contact Finish Variation: 68683-425 or 76342-425LF For applications where tin mating contact finish is acceptable, these alternatives provide active product status. 68683-425 maintains 1000V rating; 76342-425LF voltage rating is not specified.

Not Recommended: 68682-625, 68683-625 These parts carry RoHS non-compliant status, limiting suitability for new designs despite meeting core electrical parameters.

Frequently Asked Questions (FAQ)

Q: Can 68683-325LF directly replace 960250-6202-AR in existing designs? A: Yes. Both connectors share 50-position configuration, 0.100" mating pitch, 2-row layout, gold contact finish, 1000V rating, and through-hole solder termination. The 68683-325LF is active with RoHS compliance, addressing the obsolescence of the original part.

Q: What is the difference between 68683-325LF and 76342-325LF? A: Both are 50-position, 0.100" pitch gold-plated receptacles with active status and RoHS compliance. Primary differences are insulation material (polyphenylene sulfide vs. thermoplastic glass-filled) and mated stacking height specification (76342-325LF specifies 11.04mm). Electrical performance is equivalent.

Q: Why do some substitutes not list operating temperature or voltage ratings? A: Data availability varies by manufacturer documentation. Parts from the TE Connectivity 2-215307-5 and Amphenol 76342 series do not include these specifications in the provided technical data. Contact manufacturers directly for complete ratings if these parameters are critical to application requirements.

Q: Can I use 68683-425 (tin finish) instead of gold finish? A: Contact finish selection depends on application requirements. Tin finish provides cost reduction but differs in corrosion resistance and contact resistance characteristics compared to gold. Substitution is electrically valid at 1000V and 2A ratings but requires design review for your specific environment.

Q: What does "RoHS Compliant" mean for connector selection? A: RoHS compliance indicates the part meets Restriction of Hazardous Substances regulations, restricting lead, cadmium, mercury, and other hazardous materials. For new designs or regulated industries, RoHS-compliant alternatives (68683-325LF, 76342-325LF, 76342-325HLF, 76342-425LF, 2-215307-5) are required.

Q: Are there mechanical compatibility concerns between substitutes? A: All listed substitutes maintain 50-position, 0.100" pitch, 2-row configuration with through-hole mounting. Minor variations exist in insulation height (0.275" to 0.280") and contact post length (0.114" to 0.122"). Verify PCB footprint and mating connector compatibility before final selection.
