Engineering Selection Recommendations

A3C-14DA-2DSC(71) is the direct equivalent from Hirose Electric Co Ltd. This part maintains identical electrical and mechanical specifications to the original A3C-14DA-2DSC while offering active product status and RoHS compliance. Selection of this part is appropriate for applications requiring continuity with the original Hirose A3 series design.

SMM-107-01-S-D from Samtec Inc. is a cross-manufacturer substitute that meets all core substitution criteria. This connector provides enhanced electrical performance with 3.2A per contact current rating and 350VAC voltage rating, compared to 1A and 200VAC of the original. The operating temperature range extends to 125°C. This part is suitable for applications requiring higher electrical performance margins or extended temperature operation. ROHS3 compliance is provided.

Both substitute parts maintain the critical mechanical interface parameters: 14-position configuration, 0.079" (2.00mm) pitch, 2-row arrangement, through-hole solder termination, and push-pull fastening. All three connectors carry UL94 V-0 flammability certification.

Frequently Asked Questions (FAQ)

Q: Can the A3C-14DA-2DSC(71) be used as a direct replacement for the obsolete A3C-14DA-2DSC?

A: Yes. The A3C-14DA-2DSC(71) maintains identical electrical and mechanical specifications, including pitch, position count, row spacing, current rating, voltage rating, and operating temperature range. The primary differences are active product status and RoHS compliance.

Q: What are the key differences between the Hirose A3C-14DA-2DSC(71) and the Samtec SMM-107-01-S-D?

A: Both connectors share the same 14-position, 0.079" (2.00mm) pitch configuration and through-hole solder termination. The SMM-107-01-S-D provides higher electrical performance (3.2A per contact vs. 1A, and 350VAC vs. 200VAC) and extended operating temperature to 125°C. The SMM-107-01-S-D uses Liquid Crystal Polymer insulation and Beryllium Copper contacts, while the A3C-14DA-2DSC(71) uses Polybutylene Terephthalate insulation and Phosphor Bronze contacts.

Q: Are there packaging differences between these parts?

A: The A3C-14DA-2DSC and A3C-14DA-2DSC(71) differ in packaging, with the latter supplied in tube packaging. The SMM-107-01-S-D is also supplied in tube packaging. Verify packaging requirements for your assembly process.

Q: Do all three connectors meet the same compliance standards?

A: All three connectors carry UL94 V-0 flammability certification and have Moisture Sensitivity Level 1 (Unlimited). The A3C-14DA-2DSC is RoHS non-compliant, while both A3C-14DA-2DSC(71) and SMM-107-01-S-D are RoHS compliant. All three have REACH Unaffected status and EAR99 ECCN classification.

Q: What is the mechanical compatibility between these connectors?

A: All three connectors maintain identical mating pitch (0.079" / 2.00mm), row spacing (0.079" / 2.00mm), and push-pull fastening type. PCB footprints are compatible. Physical dimensions vary slightly; the SMM-107-01-S-D has an insulation height of 0.140" (4.66mm) compared to 0.165" (4.20mm) for the Hirose parts, and contact post length differs at 0.120" (3.05mm) versus 0.079" (2.00mm).
