Substitute parts are grouped by contact post length and contact finish specifications. The HMTSW-102-07-G-S-230 features a 0.100" (2.54mm) post length with gold mating finish. Amphenol ICC (FCI) BERGSTIK® II series parts provide direct functional equivalents with variations in post length (0.095", 0.120", 0.150", 0.183"), contact finish (gold or tin), and finish thickness. Parts with identical post length and mating finish are primary substitutes; parts with different post lengths are secondary substitutes requiring PCB design verification.

Engineering Selection Recommendations

All listed substitute parts maintain active product status and RoHS compliance, ensuring long-term availability and regulatory conformance. The primary substitutes are 68000-102HLF, 68000-202HLF, and 68000-402HLF, which share identical mating contact length and insulation height specifications with the HMTSW-102-07-G-S-230.

For applications requiring gold mating finish with minimal contact finish thickness variation, 68000-102HLF (30.0µin gold) and 68000-202HLF (15.0µin gold) are direct functional equivalents. The 68000-402HLF provides tin finish with thicker plating (100.0µin) for enhanced durability in corrosive environments.

Parts with extended post lengths (68001 series at 0.120", 68002-402HLF at 0.150", 68031-102HLF at 0.183") require PCB design verification to confirm through-hole depth compatibility. The 68031-102HLF offers increased current rating (5A) and voltage rating (110V) for higher-power applications.

The 69190-202HLF provides dual termination capability (Press-Fit and Solder) with extended operating temperature range (-65°C ~ 130°C) and alternative insulation material (PCT, Glass Filled), suitable for applications requiring enhanced thermal performance.

Frequently Asked Questions (FAQ)

Q: Can 68000-102HLF directly replace HMTSW-102-07-G-S-230 without PCB modification?

A: The 68000-102HLF is functionally equivalent for mating interface and electrical performance. However, the contact post length is 0.095" (2.41mm) compared to 0.100" (2.54mm) on the original part. PCB through-hole depth must accommodate this 0.005" (0.13mm) difference. If the PCB is designed for the original 0.100" post length, the 68000-102HLF will seat slightly higher, which may affect solder joint quality. Verify PCB design specifications before substitution.

Q: What is the difference between gold and tin finish options?

A: Gold-finished parts (68000-102HLF, 68000-202HLF, 68001 series, 68031-102HLF, 69190-202HLF) provide superior corrosion resistance and lower contact resistance, suitable for general-purpose applications. Tin-finished parts (68000-402HLF, 68001-402HLF, 68002-402HLF) offer thicker plating (100.0µin) for enhanced mechanical durability and are preferred in high-insertion-cycle or high-vibration environments. Contact finish thickness on gold parts varies from 10.0µin to 30.0µin; thicker finishes provide extended contact life.

Q: Are all substitute parts compatible with the same mating connector?

A: All listed parts maintain identical pitch (0.100"), position count (2), row configuration (1), and contact shape (square), ensuring compatibility with standard 0.100" pitch receptacles. Variations in contact post length do not affect mating interface compatibility but affect overall connector height and PCB mounting depth.

Q: What packaging formats are available?

A: The HMTSW-102-07-G-S-230 is supplied in Bulk packaging. Substitute parts are available in Bulk (68000-402, 68002-402HLF, 69190-202HLF) and Bag (68000-102HLF, 68000-202HLF, 68001-102HLF, 68001-202HLF, 68001-402HLF, 68031-102HLF) formats. Bag packaging typically includes moisture barrier protection suitable for automated assembly processes.

Q: Which substitute offers the best thermal performance?

A: The 68002-402HLF and 69190-202HLF both support extended operating temperature range (-65°C ~ 130°C) compared to the original part (-55°C ~ 125°C). The 69190-202HLF additionally features PCT glass-filled insulation material, which provides superior thermal stability and mechanical strength at elevated temperatures.

Q: Is the 68031-102HLF suitable for higher-current applications?

A: The 68031-102HLF is rated for 5A current and 110V voltage, compared to 3A on the original part. This part is suitable for applications requiring increased power handling. However, the contact post length is 0.183" (4.65mm), significantly longer than the original 0.100" (2.54mm), requiring substantial PCB design modification to accommodate the extended post length.
