Engineering Selection Recommendations

Primary Recommendation: Würth Elektronik 61231420621

The 61231420621 is the direct active equivalent from the original manufacturer. It maintains identical electrical specifications, shrouding configuration, and termination method as the discontinued 61201420621. The minor dimensional variations in contact length (0.197" vs 0.200") and insulation height (0.362" vs 0.365") fall within acceptable mechanical tolerances for standard PCB footprints. This part is ROHS3 compliant and currently in active production with Tape & Reel packaging suitable for automated assembly.

Secondary Recommendation: Assmann WSW Components AWHW 14G-SMD

The AWHW 14G-SMD provides an alternative from an established connector manufacturer. It maintains all critical electrical parameters and shrouding specifications. The contact material is brass rather than copper alloy, and insulation material is glass-filled polyamide (PA9T) instead of standard PA6T. Operating temperature range is reduced to -40°C ~ 105°C. This part is suitable for applications not requiring the full -40°C ~ 125°C range and offers high inventory availability.

Tertiary Recommendation: Samtec Inc. HTST-107 Series

The Samtec HTST-107 series (multiple variants) offers enhanced performance characteristics including phosphor bronze contacts, liquid crystal polymer insulation, and extended operating temperature range (-55°C ~ 125°C). Current rating is 3.4A per contact, exceeding the original 3A specification. These parts are available in multiple packaging options (Tube and Tape & Reel) and feature variants with Pick and Place capability and board guides. The "L" designation indicates low-profile construction; "LM" indicates low-profile with mated stacking. The "A" and "P" suffixes indicate specific contact finish and post configurations.

All substitute parts maintain ROHS3 compliance and UL94 V-0 flammability rating. Selection should be based on packaging requirements (Tube vs. Tape & Reel), assembly process capabilities (Pick and Place features), and thermal operating envelope of the target application.

Frequently Asked Questions (FAQ)

Q: Can I use the Samtec HTST-107 series as a direct replacement for the Würth Elektronik 61201420621?

A: Yes. The HTST-107 series maintains all critical electrical and mechanical parameters: 14 positions, 2.54mm pitch, 2-row configuration, shrouded 4-wall construction, solder termination, and push-pull fastening. The contact length is longer (0.250" vs 0.200"), which is acceptable for standard PCB designs. Verify PCB footprint compatibility before production implementation.

Q: What is the difference between the Samtec HTST-107-01-L-DV-A and HTST-107-01-L-DV-A-P variants?

A: Both parts are electrically and mechanically identical. The "-P" suffix indicates Pick and Place feature compatibility, which facilitates automated assembly processes. Select the "-P" variant if your manufacturing process uses automated component placement equipment.

Q: Why does the Assmann AWHW 14G-SMD have a lower maximum operating temperature (-40°C ~ 105°C) compared to the original part (-40°C ~ 125°C)?

A: The AWHW 14G-SMD uses glass-filled polyamide (PA9T) insulation material, which has a lower thermal rating than the standard polyamide (PA6T) used in the original part. This part is suitable for applications with maximum operating temperatures up to 105°C. For applications requiring 125°C operation, select the Würth Elektronik 61231420621 or Samtec HTST-107 series.

Q: What packaging options are available for these substitute parts?

A: The Würth Elektronik 61231420621 is supplied in Tape & Reel (TR) packaging. The Assmann AWHW 14G-SMD is supplied in Tube packaging. The Samtec HTST-107 series is available in both Tube and Tape & Reel variants. Select Tape & Reel packaging for high-volume automated assembly; select Tube packaging for lower-volume or manual assembly processes.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and carry UL94 V-0 flammability ratings, matching the compliance profile of the original 61201420621.

Q: What is the difference between the Samtec HTST-107-01-L-DV-A and HTST-107-01-LM-DV-A variants?

A: The "L" designation indicates low-profile construction; the "LM" designation indicates low-profile with mated stacking capability. Both variants are electrically and mechanically equivalent. The "LM" variant provides additional mechanical flexibility for applications requiring stacked connector configurations.

Q: Can I mix substitute parts from different manufacturers in the same design?

A: All substitute parts maintain identical electrical specifications and mechanical interfaces at the mating surface. However, for production consistency and supply chain management, it is recommended to standardize on a single part number per design revision.
