Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with RoHS and REACH requirements. The HMTSW-101-07-G-S-240 is ROHS3 Compliant with REACH Unaffected status. Substitute parts 68000-101HLF, 68001-101HLF, and 861400011YO2LF maintain REACH Unaffected status, while 68001-201HLF is REACH Affected.

Selection between the main part and substitutes depends on design accommodation of dimensional variations. The 68000-101HLF and 68001-101HLF variants from the BERGSTIK® II series offer extended lower operating temperature range (-65°C versus -55°C). The 861400011YO2LF from the BERGSTIK® series provides the longest overall contact length at 0.496" (12.60mm) and includes voltage rating specification of 1000V.

Contact finish thickness varies across all parts, ranging from 8.00µin to 30.0µin on the mating surface. Designs requiring specific contact finish thickness specifications should reference the detailed parameter comparison.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the HMTSW-101-07-G-S-240?

A: Core substitution criteria include identical connector type (Header), contact type (Male Pin), single position, single row configuration, through-hole mounting, solder termination, push-pull fastening, square contact shape, 3A current rating, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. Variations in contact length, insulation material, and contact finish thickness are permitted within the specified ranges.

Q: Are there packaging differences between the main part and substitutes?

A: Yes. The HMTSW-101-07-G-S-240 is supplied in Bulk packaging. Substitute 68000-101HLF is supplied in Bag packaging. Substitutes 68001-201HLF and 861400011YO2LF are supplied in Bulk packaging. Packaging selection may affect procurement and handling procedures.

Q: What is the significance of contact finish thickness variation?

A: Contact finish thickness affects durability and wear characteristics. The HMTSW-101-07-G-S-240 specifies 10.0µin (0.25µm) mating finish thickness. Substitutes range from 8.00µin to 30.0µin. Thicker finishes provide extended contact life in high-cycle mating applications, while thinner finishes reduce material cost.

Q: Do all substitutes support the same operating temperature range?

A: No. The HMTSW-101-07-G-S-240 operates from -55°C to 125°C. Amphenol ICC BERGSTIK® II variants (68000-101HLF, 68001-101HLF, 68001-201HLF) extend the lower limit to -65°C. The BERGSTIK® variant (861400011YO2LF) maintains the -55°C to 125°C range. Design requirements for low-temperature operation should specify the extended-range substitutes.

Q: What is the REACH compliance status difference?

A: The main part HMTSW-101-07-G-S-240 and substitutes 68000-101HLF and 861400011YO2LF are REACH Unaffected. Substitutes 68001-101HLF and 68001-201HLF are REACH Affected. Applications subject to REACH restrictions should specify REACH Unaffected parts.

Q: How do contact length variations affect board design?

A: Contact length variations directly impact PCB stack-up and mating depth. The HMTSW-101-07-G-S-240 has 0.240" mating contact length and 0.090" post length. Substitutes range from 0.230" to 0.276" mating length and 0.095" to 0.118" post length. Board designs must accommodate these dimensional differences to ensure proper mating alignment and electrical contact.
