Termination: Solder
Fastening Type: Push-Pull
Style: Board to Board or Cable

Secondary Compatibility Factors:

Contact Shape: Square
Material Flammability Rating: UL94 V-0

The substitute parts are grouped into two categories:

Category 1: Direct Hirose Equivalent A3-14PA-2SV(71) is the active production variant of the obsolete A3-14PA-2SV, maintaining identical electrical and mechanical specifications while offering improved RoHS3 compliance and enhanced contact finish specifications.

Category 2: Cross-Manufacturer Alternatives Harwin M22-5320705R and Samtec TMM-107 series connectors provide functional equivalence through matching pitch, position count, row configuration, and mounting methodology. These alternatives differ in contact material composition, insulation material, and operating temperature ranges but maintain compatibility with the core mating interface requirements.

Engineering Selection Recommendations

Primary Recommendation: A3-14PA-2SV(71)

The A3-14PA-2SV(71) is the direct active equivalent from Hirose Electric Co Ltd. This part maintains identical mechanical and electrical specifications to the obsolete A3-14PA-2SV while offering ROHS3 compliance and enhanced contact finish specifications with defined thickness tolerances. Selection of this part eliminates design re-qualification requirements and maintains full compatibility with existing PCB layouts and mating connectors.

Secondary Recommendation: Harwin M22-5320705R

The M22-5320705R provides cross-manufacturer equivalence with ROHS3 compliance and extended operating temperature range (-40°C to 105°C). This part features a cuttable header design and phosphor bronze contact material. The insulation height is reduced to 0.059" (1.50mm) compared to the original 0.071" (1.80mm), requiring verification of PCB clearance and mating connector compatibility.

Tertiary Recommendation: Samtec TMM-107 Series

The Samtec TMM-107 series offers multiple contact finish options (gold or tin) with enhanced current rating (3.2A per contact) and extended operating temperature range (-55°C to 125°C). These parts feature liquid crystal polymer insulation and phosphor bronze contacts. Contact length is reduced to 0.065" (1.65mm), and insulation height is 0.059" (1.50mm). Selection from this series requires verification of mating connector compatibility and PCB layout accommodation.

Compliance Consideration:

All active substitute parts provide ROHS3 compliance, addressing the non-compliant status of the obsolete A3-14PA-2SV. Selection should prioritize compliance requirements for new designs or redesigns.

Frequently Asked Questions (FAQ)

Q: Can A3-14PA-2SV(71) be used as a direct replacement for A3-14PA-2SV?

A: Yes. The A3-14PA-2SV(71) maintains identical pitch (2.00mm), position count (14), row configuration (2 rows), contact type (male pin), and mounting methodology (surface mount solder). PCB layouts and mating connectors designed for A3-14PA-2SV are compatible with A3-14PA-2SV(71).

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

A: Contact material differs (Hirose uses brass; Samtec uses phosphor bronze). Insulation material differs (Hirose uses PPS; Samtec uses LCP). Contact length is shorter in Samtec parts (0.065" vs. 0.138"). Samtec parts offer higher current rating (3.2A vs. 1A) and extended temperature range (-55°C to 125°C vs. -55°C to 85°C).

Q: Are Samtec TMM-107 variants interchangeable with each other?

A: Samtec TMM-107 variants share identical pitch, position count, row spacing, and mechanical envelope. Variants differ in contact finish (gold or tin) and board guide features. Selection depends on application requirements for contact finish material and board alignment needs.

Q: What is the impact of reduced contact length in cross-manufacturer alternatives?

A: Reduced contact length (0.065" in Samtec vs. 0.138" in original) affects mating depth and connector engagement. PCB layout and mating connector compatibility must be verified before substitution. Existing designs may require modification to accommodate shorter contact engagement.

Q: Do all substitute parts meet the same flammability and moisture sensitivity requirements?

A: Yes. All substitute parts maintain UL94 V-0 material flammability rating and Moisture Sensitivity Level 1 (Unlimited), matching the original A3-14PA-2SV specifications.

Q: Which substitute part offers the best thermal performance?

A: Samtec TMM-107 series parts offer the highest operating temperature range (-55°C to 125°C), compared to -55°C to 85°C for the original and -40°C to 105°C for Harwin M22-5320705R. Selection depends on application thermal requirements.
