Engineering Selection Recommendations

Amphenol ICC 68683-425 (Primary Part) Select this part for applications requiring tin contact finish and RoHS non-compliant specifications. The 1000V voltage rating and -65°C to 125°C operating range support demanding automotive and industrial environments. Moisture sensitivity level 1 indicates no special handling requirements.

TE Connectivity 2-215307-5 (Substitute) This part provides ROHS3 compliance with gold contact finish, suitable for applications requiring enhanced environmental protection and regulatory compliance. The green insulation color and polyester glass-filled insulation material offer alternative mechanical properties. Packaging in trays differs from the tube packaging of the primary part. Voltage and operating temperature specifications are not provided; verification against application requirements is necessary before selection.

Samtec BCS-125-L-D-TE (Substitute) This part delivers ROHS3 compliance, REACH unaffected status, and gold contact finish with the lowest contact finish thickness (10.0µin). The 475VAC voltage rating and -55°C to 125°C operating range define specific application boundaries. Liquid crystal polymer insulation material provides distinct mechanical characteristics. Current rating of 4.6A per contact is specified. Moisture sensitivity is not applicable. Tube packaging matches the primary part format.

Selection between substitutes depends on compliance requirements, contact finish preference, voltage/current specifications, and insulation material compatibility with the target application.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-215307-5 directly replace the Amphenol ICC 68683-425 in all applications?

A: Direct replacement is mechanically and electrically feasible based on matching pitch, position count, row configuration, and fastening type. However, the TE part does not specify voltage and operating temperature ratings. Applications requiring the full 1000V rating or -65°C lower temperature limit must be evaluated against the TE part's unspecified parameters. The gold contact finish and ROHS3 compliance may require design validation in existing circuits.

Q: What are the key differences between tin and gold contact finishes in these connectors?

A: The 68683-425 features tin contact finish (100.0µin thickness), while both substitute parts use gold finish (31.5µin for TE, 10.0µin for Samtec). Contact finish affects corrosion resistance, contact resistance, and mating force characteristics. Gold provides superior corrosion resistance in harsh environments; tin offers cost efficiency in controlled conditions. Selection depends on environmental exposure and circuit performance requirements.

Q: Are there packaging differences between these parts?

A: The Amphenol ICC 68683-425 and Samtec BCS-125-L-D-TE are supplied in tubes. The TE Connectivity 2-215307-5 is supplied in trays. Packaging affects handling, storage, and automated assembly compatibility. Verify packaging compatibility with procurement and assembly processes before substitution.

Q: What compliance certifications differ between these parts?

A: The 68683-425 is RoHS non-compliant. Both substitute parts (TE 2-215307-5 and Samtec BCS-125-L-D-TE) are ROHS3 compliant. The Samtec part additionally carries REACH unaffected status. Applications subject to RoHS or REACH regulations must use compliant substitutes. Non-regulated applications may use any part based on performance criteria.

Q: How do insulation material differences affect connector performance?

A: The 68683-425 uses polyphenylene sulfide (PPS) glass-filled insulation. The TE part uses polyester glass-filled material. The Samtec part uses liquid crystal polymer (LCP) glass-filled material. These materials differ in thermal stability, mechanical strength, and chemical resistance. Material selection impacts performance in high-temperature, high-vibration, or chemically aggressive environments. Verify material compatibility with application conditions.

Q: What is the significance of the contact length difference between these parts?

A: The 68683-425 has a contact post length of 0.115" (2.92mm), while both substitutes measure 0.122" (3.10mm). This 0.007" difference affects mating depth and PCB stack-up compatibility. In applications with tight mechanical constraints or specific mating depth requirements, this variation may necessitate design review or mechanical adjustment.

Q: Can the Samtec BCS-125-L-D-TE be used in applications exceeding 475VAC?

A: No. The Samtec part is rated for 475VAC maximum. The Amphenol ICC 68683-425 is rated for 1000V. Applications requiring voltage ratings above 475VAC must use the primary part or verify that the TE Connectivity 2-215307-5 meets voltage requirements (specifications not provided). Exceeding rated voltage voids component reliability and safety margins.
