Engineering Selection Recommendations

Direct Hirose Equivalent: A3C-6P-2DSA(30) is the active production variant of the obsolete A3C-6P-2DSA, maintaining identical electrical and mechanical specifications while offering RoHS compliance and active product status. This part is the primary replacement for direct substitution.

Harwin Alternative: M22-2020346 provides cross-manufacturer compatibility with cuttable header functionality and extended operating temperature range (-40°C to 105°C). This part is suitable for applications requiring higher temperature performance within the specified pitch and position constraints.

Samtec Alternatives: The MTMM-103 series (variants -02-F-D and -02-G-D) offers enhanced current rating (3A versus 1A) and extended operating temperature range (-55°C to 125°C). These parts feature cuttable header design and ROHS3 compliance. Selection among MTMM variants depends on contact length requirements and finish specifications:

MTMM-103-02-F-D variants (124, 125, 140, 142) feature tin-plated posts with gold-plated mating contacts
MTMM-103-02-G-D variants (127, 131, 133, 134) feature gold-plated posts and mating contacts

All substitute parts maintain UL94 V-0 flammability rating, MSL 1 classification, and mechanical compatibility with the original A3C-6P-2DSA footprint.

Frequently Asked Questions (FAQ)

Q: Can A3C-6P-2DSA(30) be used as a direct replacement for A3C-6P-2DSA?

A: Yes. A3C-6P-2DSA(30) maintains identical pitch (0.079"), position count (6), row configuration (2 rows), and all critical electrical parameters. The primary difference is active product status and RoHS compliance. Packaging format differs (bulk versus original), but electrical and mechanical compatibility is complete.

Q: What are the key differences between Hirose and Samtec alternatives?

A: Hirose A3C-6P-2DSA(30) maintains the original operating temperature range (-55°C to 85°C) and 1A current rating. Samtec MTMM-103 series provides higher current capacity (3A) and extended temperature range (-55°C to 125°C), with cuttable header design. Both maintain 0.079" pitch and 6-position, 2-row configuration.

Q: Are contact length variations between substitute parts significant?

A: Contact length variations exist among Samtec MTMM-103 variants (ranging from 0.124" to 0.142" mating contact length). These variations affect mating depth and stacking height. Selection depends on specific PCB design requirements and mating connector specifications. All variants maintain electrical compatibility within the 0.079" pitch constraint.

Q: What is the significance of contact finish differences?

A: MTMM-103-02-F-D variants feature tin-plated posts with gold-plated mating contacts. MTMM-103-02-G-D variants feature gold-plated posts and mating contacts. Both configurations provide equivalent electrical performance. Selection depends on soldering process compatibility and environmental exposure requirements.

Q: Do all substitute parts meet the same compliance standards?

A: All substitute parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification. Samtec and Harwin alternatives provide ROHS3 compliance, while the original A3C-6P-2DSA does not specify RoHS status. A3C-6P-2DSA(30) provides RoHS compliance. Compliance requirements should be verified against specific application standards.

Q: Is the cuttable header feature of Samtec and Harwin parts compatible with the original design?

A: Cuttable header design does not affect electrical or mechanical compatibility with standard mating connectors. The feature provides additional flexibility for custom configurations but does not impact performance in applications using standard 6-position, 2-row mating connectors.
