Engineering Selection Recommendations

All four substitute parts are active products with ROHS3 compliance and unlimited moisture sensitivity rating, matching the regulatory and environmental requirements of the Molex 0872631403.

Hirose A3-14DA-2SV(71) and A3A-14DA-2SV(71): These parts maintain the same 1A current rating and provide higher voltage rating (200VAC vs. 125VAC). The A3A-14DA-2SV(71) variant includes board guide features. Operating temperature range is reduced to -55°C to 85°C. Insulation height is increased to 0.165" (4.20mm). Contact material is phosphor bronze with polyphenylene sulfide insulation.

Samtec SMM-107-02-S-D-K-TR and SMM-107-02-S-D-P-TR: These Tiger Eye™ SMM series parts provide enhanced electrical performance with 3.2A per contact current rating and 350VAC voltage rating. Operating temperature extends to 125°C. Insulation height is 0.140" (4.66mm). Contact material is beryllium copper with liquid crystal polymer insulation. Both variants are supplied in tape and reel packaging. The SMM-107-02-S-D-P-TR variant includes pick and place features.

Selection between substitutes depends on application requirements for current capacity, voltage rating, operating temperature range, and packaging format.

Frequently Asked Questions (FAQ)

Q: Can the Hirose A3-14DA-2SV(71) be used as a direct replacement for the Molex 0872631403?

A: Yes, within the constraints of the reduced operating temperature range (-55°C to 85°C vs. -55°C to 105°C). The connector maintains identical pitch, position count, row configuration, mounting method, and fastening type. The higher voltage rating (200VAC) and increased insulation height do not prevent mechanical or electrical compatibility at the mating interface.

Q: What is the difference between the Hirose A3-14DA-2SV(71) and A3A-14DA-2SV(71)?

A: Both parts are electrically and mechanically identical. The A3A-14DA-2SV(71) includes board guide features, while the A3-14DA-2SV(71) does not. Both are supplied in tube packaging.

Q: Why do the Samtec SMM-107 parts have higher current and voltage ratings?

A: The Samtec Tiger Eye™ SMM series uses beryllium copper contacts with liquid crystal polymer insulation, enabling higher electrical performance specifications. These parts are suitable for applications requiring 3.2A per contact and 350VAC operation.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. The Molex 0872631403 is supplied in bulk packaging. Hirose parts are supplied in tubes. Samtec parts are supplied in tape and reel format. Packaging selection affects handling, storage, and automated assembly processes.

Q: What is the impact of insulation height differences?

A: Insulation height affects the overall connector profile and mated stacking height. The Molex part has 0.110" (2.79mm) insulation height, while Hirose parts are 0.165" (4.20mm) and Samtec parts are 0.140" (4.66mm). PCB layout and clearance requirements must accommodate these dimensional variations.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with unlimited moisture sensitivity rating, matching the regulatory status of the Molex 0872631403.
