The primary substitute is M80-6651642 from Harwin Inc., which maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. Secondary substitutes are from Samtec Inc.'s TSH series (TSH-108-01-L-DH, TSH-108-01-T-DH-SL, TSH-108-01-S-DH, TSH-108-01-SM-DH-SL), which share the same pitch, position count, row configuration, and mounting orientation. These Samtec alternatives feature different shrouding (3-wall vs. 4-wall), fastening mechanisms (push-pull vs. friction lock), and contact materials (phosphor bronze vs. brass), but maintain functional compatibility for board-to-board applications.

Engineering Selection Recommendations

For applications currently using the M80-6671622, the M80-6651642 from Harwin Inc. is the primary recommended substitute. This part maintains identical electrical and mechanical specifications, identical shrouding configuration (4-wall), and identical insulation material (PPS glass-filled), while offering active product status and ROHS3 compliance. The fastening mechanism differs (latch holder vs. friction lock), but both provide secure mating.

The Samtec TSH series (TSH-108-01-L-DH, TSH-108-01-S-DH, TSH-108-01-SM-DH-SL, and TSH-108-01-T-DH-SL) provides functional alternatives for applications where shrouding configuration and fastening mechanism can be adapted. These parts maintain the critical pitch, position count, row spacing, and mounting orientation. The TSH-108-01-T-DH-SL variant operates at a reduced maximum temperature of -55°C ~ 105°C and features tin mating contact finish rather than gold, which may impact suitability for specific applications.

All substitute parts maintain UL94 V-0 flammability rating and are ROHS3 compliant, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can M80-6651642 be used as a direct replacement for M80-6671622?

A: Yes. Both parts share identical pitch (2.00mm), position count (16), row configuration (2 rows), row spacing (2.00mm), mounting type (surface mount right-angle), shrouding (4-wall), termination (solder), operating temperature range (-55°C ~ 125°C), and flammability rating (UL94 V-0). The fastening mechanism differs (latch holder vs. friction lock), but both provide secure mating. M80-6651642 is active and ROHS3 compliant.

Q: What are the key differences between Harwin and Samtec substitutes?

A: Harwin M80-6651642 maintains the 4-wall shrouding and PPS glass-filled insulation of the original. Samtec TSH series parts feature 3-wall shrouding, LCP insulation material, push-pull fastening, and phosphor bronze contacts instead of brass. Insulation height is reduced (0.157" vs. 0.235"). These differences may affect mechanical fit and mating force characteristics.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. M80-6651642 and all Samtec TSH variants (TSH-108-01-L-DH, TSH-108-01-T-DH-SL, TSH-108-01-S-DH, TSH-108-01-SM-DH-SL) are ROHS3 compliant. The original M80-6671622 is RoHS non-compliant.

Q: Does TSH-108-01-T-DH-SL have any temperature limitations?

A: Yes. TSH-108-01-T-DH-SL operates at -55°C ~ 105°C, which is 20°C lower than the original M80-6671622 (-55°C ~ 125°C). All other TSH variants and M80-6651642 maintain the full -55°C ~ 125°C range.

Q: What is the difference between TSH variants with and without solder retention?

A: TSH-108-01-L-DH and TSH-108-01-S-DH do not include solder retention features. TSH-108-01-T-DH-SL and TSH-108-01-SM-DH-SL include solder retention. Solder retention prevents solder from flowing into the mating cavity during assembly.

Q: Can contact finish differences affect compatibility?

A: Contact finish affects electrical performance and environmental resistance. The original M80-6671622 features gold mating contacts (29.5µin thickness). M80-6651642 and most TSH variants maintain gold finish. TSH-108-01-T-DH-SL uses tin mating contacts, which may have different contact resistance and corrosion characteristics. Application requirements should determine acceptability.

Q: Are there packaging differences between substitutes?

A: M80-6671622 packaging is not specified. M80-6651642 is supplied in tube packaging. All Samtec TSH variants are supplied in tube packaging. Packaging differences do not affect electrical or mechanical compatibility.
