Engineering Selection Recommendations

All substitute parts listed are active products with RoHS compliance and UL94 V-0 flammability ratings, meeting the same regulatory and safety standards as the TE Connectivity 6-146254-2. Selection among substitute parts is determined by specific application requirements and mechanical constraints.

67996-124HLF (Amphenol ICC/FCI): This part features gold plating on mating contacts with a contact post length of 0.095" (2.41mm), resulting in the shortest overall contact length of 0.425" (10.80mm). Operating temperature range extends to 125°C. This configuration is suitable for applications requiring enhanced corrosion resistance through gold plating and where reduced post length accommodates tighter PCB spacing constraints.

67997-124HLF (Amphenol ICC/FCI): This part matches the contact post length of 0.120" (3.05mm) to the main part, with gold plating on mating contacts and an operating temperature range of 130°C. The overall contact length of 0.450" (11.43mm) provides compatibility with standard PCB hole depths. This part offers direct dimensional equivalence with enhanced temperature performance.

67997-424HLF (Amphenol ICC/FCI): This part features tin plating on both mating and post contacts, matching the finish specification of the main part. Contact post length is 0.120" (3.05mm), and operating temperature extends to 130°C. This configuration provides the closest material and finish alignment to the original TE Connectivity part while offering improved temperature performance.

68602-224HLF (Amphenol ICC/FCI): This part features gold plating with the longest contact post length of 0.150" (3.81mm) and overall contact length of 0.480" (12.19mm). Operating temperature range reaches 130°C. This configuration is suitable for applications requiring extended post length for deeper PCB penetration or where additional contact engagement is necessary.

All substitute parts maintain identical mating interface dimensions, pitch spacing, and electrical current ratings, ensuring direct functional compatibility with mating connectors and PCB layouts designed for the TE Connectivity 6-146254-2.

Frequently Asked Questions (FAQ)

Q: Can the substitute parts be used interchangeably with the TE Connectivity 6-146254-2 in existing designs?

A: Yes, all substitute parts maintain identical mating pitch (0.100" / 2.54mm), number of positions (24), row configuration (2 rows), and contact type (male pin). The mating interface is fully compatible. However, variations in overall contact length and post length must be evaluated against specific PCB hole depth and mechanical envelope requirements.

Q: What is the difference between tin and gold plating on the mating contacts?

A: Tin plating (100.0µin / 2.54µm) provides cost-effective corrosion resistance suitable for standard applications. Gold plating (30.0µin to 15.0µin) offers enhanced corrosion resistance and lower contact resistance, beneficial for high-reliability applications or environments with corrosive exposure. The main part (6-146254-2) and 67997-424HLF use tin plating, while 67996-124HLF, 67997-124HLF, and 68602-224HLF use gold plating.

Q: How do contact post length variations affect PCB compatibility?

A: Contact post length determines how far the solder tail extends into the PCB hole. The main part specifies 0.120" (3.05mm). Substitute parts range from 0.095" (2.41mm) to 0.150" (3.81mm). Shorter posts (67996-124HLF at 0.095") suit thin PCBs or tight spacing; longer posts (68602-224HLF at 0.150") accommodate thicker PCBs or provide additional solder joint strength. PCB design specifications must be consulted to ensure compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes, all substitute parts listed are RoHS compliant and carry UL94 V-0 flammability ratings, matching the regulatory compliance of the main part.

Q: What is the significance of the operating temperature range differences?

A: The main part operates from -65°C to 105°C. Substitute parts extend this range to 125°C or 130°C, providing additional thermal margin for applications in elevated-temperature environments. This does not affect compatibility in standard temperature applications but offers design flexibility for thermal-constrained designs.

Q: Does contact material (Copper Alloy vs. Phosphor Bronze) affect electrical performance?

A: Both materials provide adequate electrical conductivity for the 3A current rating. Phosphor Bronze (used in all substitute parts) offers superior spring characteristics and wear resistance compared to Copper Alloy (used in the main part), potentially extending contact life in high-cycle mating applications. For standard applications, both materials perform equivalently.

Q: What packaging differences exist between the main part and substitutes?

A: The main part (6-146254-2) is supplied in bulk packaging, while all substitute parts are supplied in bag packaging. This affects inventory management and handling but does not impact electrical or mechanical performance.

Q: Can I mix different substitute parts in the same assembly?

A: All substitute parts are mechanically and electrically compatible with each other due to identical mating interface dimensions and electrical ratings. However, assembly consistency and traceability practices should be considered when selecting a single part number for production designs.
