Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the A3C-12DA-2DSC(71) are qualified based on the following critical parameters that determine functional interchangeability:

Core Matching Criteria:

• 12-position connector configuration
• 0.079" (2.00mm) mating pitch
• 2-row arrangement with 0.079" (2.00mm) row spacing
• Through-hole solder termination
• Gold-plated mating contacts
• Push-pull fastening type
• UL94 V-0 flammability rating
• ROHS3 compliance

Identified Substitutes:

NPPN062AFCN-RC (Sullins Connector Solutions): Qualifies as a substitute despite connector type designation as header. Meets all core matching criteria including 12-position, 2.00mm pitch, 2-row configuration, through-hole solder termination, and gold mating contacts. Shares identical electrical ratings (1A current) and compliance certifications.

SMM-106-01-S-D (Samtec Inc.): Qualifies as a substitute with identical receptacle connector type. Meets all core matching criteria including 12-position, 2.00mm pitch, 2-row configuration, through-hole solder termination, and gold mating contacts. Exceeds electrical performance specifications with 3.2A per contact rating and 350VAC voltage rating.

Parameter Comparison

Engineering Selection Recommendations

Selection between the A3C-12DA-2DSC(71) and its substitutes is determined by application requirements and compliance certifications:

A3C-12DA-2DSC(71) (Hirose Electric): Primary choice for applications requiring the original specification. Active product status with 1107 units in stock. Meets all ROHS3 and REACH compliance requirements. Suitable for general purpose and telecommunications applications within the specified -55°C to 85°C operating range and 200VAC voltage rating.

NPPN062AFCN-RC (Sullins Connector Solutions): Functionally equivalent substitute with identical electrical ratings and compliance certifications. Active product status with 1238 units in stock. Extended operating temperature range (-40°C to 105°C) provides flexibility for higher-temperature environments. Header connector type designation does not affect mechanical or electrical interchangeability with receptacle mating interfaces. Suitable when Sullins sourcing is preferred or inventory availability is critical.

SMM-106-01-S-D (Samtec Inc.): Performance-enhanced substitute with superior electrical ratings (3.2A per contact, 350VAC). Active product status with 1334 units in stock. Extended operating temperature range (-55°C to 125°C) and beryllium copper contact material provide enhanced durability. Suitable for applications requiring higher current capacity or voltage margins. Tiger Eye™ SMM series designation indicates specialized design for demanding applications.

All three parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and unlimited moisture sensitivity level (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can NPPN062AFCN-RC be used as a direct replacement for A3C-12DA-2DSC(71)?

A: Yes. Despite the header connector type designation, NPPN062AFCN-RC meets all core matching criteria: 12-position configuration, 0.079" (2.00mm) pitch, 2-row arrangement, through-hole solder termination, gold mating contacts, and identical current rating (1A). The connector type designation does not affect mechanical or electrical interchangeability when mating with receptacle interfaces.

Q: What are the key differences between SMM-106-01-S-D and the original A3C-12DA-2DSC(71)?

A: SMM-106-01-S-D provides enhanced electrical performance with 3.2A per contact (versus 1A) and 350VAC rating (versus 200VAC). Operating temperature range extends to 125°C (versus 85°C). Contact material is beryllium copper instead of phosphor bronze. Insulation material is liquid crystal polymer (LCP) instead of polybutylene terephthalate (PBT). All other mechanical parameters including pitch, row spacing, and termination method remain identical.

Q: Are all three parts ROHS3 compliant?

A: Yes. A3C-12DA-2DSC(71), NPPN062AFCN-RC, and SMM-106-01-S-D are all ROHS3 compliant with REACH unaffected status and unlimited moisture sensitivity level (MSL 1).

Q: Which substitute offers the widest operating temperature range?

A: SMM-106-01-S-D provides the widest operating temperature range at -55°C to 125°C, compared to -55°C to 85°C for the original A3C-12DA-2DSC(71) and -40°C to 105°C for NPPN062AFCN-RC.

Q: Can SMM-106-01-S-D be used in applications rated for 1A at 200VAC?

A: Yes. SMM-106-01-S-D exceeds the original specifications with 3.2A per contact and 350VAC rating, making it suitable for applications requiring the original 1A at 200VAC performance.

Q: What is the difference in packaging between these parts?

A: A3C-12DA-2DSC(71) is supplied in tray packaging. NPPN062AFCN-RC and SMM-106-01-S-D are supplied in tube packaging. Packaging format does not affect connector functionality or interchangeability.
