Engineering Selection Recommendations

Hirose A3A-10DA-2SV(71) is suitable for applications where the operating temperature range of -55°C to 85°C is acceptable and voltage requirements do not exceed 200VAC. This part maintains ROHS3 compliance and UL94 V-0 flammability rating. The higher insulation height (0.165" vs. 0.110") must be evaluated for PCB layout compatibility.

Samtec Tiger Eye™ SMM Series variants provide enhanced electrical performance with 3.2A per contact current rating and 350VAC voltage rating, supporting extended operating temperatures to 125°C. These parts are suitable for applications requiring higher current capacity or voltage margins. Selection between variants depends on packaging requirements (Tube vs. Tape & Reel), position loading (9 vs. 10 positions), and optional features (Board Lock, Pick and Place capability).

SMM-105-02-S-D-TR offers the highest inventory availability (4454 units) in Tape & Reel packaging, suitable for high-volume automated assembly processes. SMM-105-02-S-D-LC provides Board Lock feature in Tube packaging for manual assembly environments.

All substitute parts maintain ROHS3 compliance, UL94 V-0 rating, and MSL 1 moisture sensitivity level, ensuring regulatory and environmental compatibility with the original Molex 0872631003.

Frequently Asked Questions (FAQ)

Q: Can the Hirose A3A-10DA-2SV(71) be used in applications requiring operation above 85°C?

A: No. The Hirose part is rated to -55°C to 85°C maximum. Applications requiring operation to 105°C or higher must use the Molex 0872631003 or Samtec SMM series variants rated to 125°C.

Q: What is the difference between Samtec SMM-105-02-S-D-LC and SMM-105-02-S-D-TR?

A: Both parts are electrically and mechanically identical with matching pitch, position count, and current/voltage ratings. The primary difference is packaging: SMM-105-02-S-D-LC is supplied in Tube packaging for manual assembly, while SMM-105-02-S-D-TR is supplied in Tape & Reel format for automated pick-and-place assembly. SMM-105-02-S-D-TR includes Pick and Place feature designation.

Q: Are all substitute parts compatible with the same mating connectors as the Molex 0872631003?

A: Compatibility depends on the specific mating connector design. All listed substitutes share the 0.079" (2.00mm) pitch and 10-position receptacle configuration. However, mechanical features such as insulation height, contact shape (circular vs. square), and fastening mechanism details must be verified against the mating plug connector specifications.

Q: What is the significance of "Number of Positions Loaded" in the Samtec variants?

A: This parameter indicates how many of the 10 available positions contain contacts. SMM-105-02-F-D-LC-09 and SMM-105-02-S-D-09 have 9 positions loaded, while other variants have all 10 positions loaded. This affects the physical footprint and contact arrangement on the PCB.

Q: Can the Samtec SMM series be used as a direct drop-in replacement for the Molex 0872631003?

A: Electrical and mechanical compatibility is confirmed for pitch, position count, and surface mount configuration. However, differences in insulation height (0.140" vs. 0.110"), contact shape (square vs. circular), and contact material (Beryllium Copper vs. unspecified) require PCB layout and mating connector verification before implementation.

Q: Which substitute part offers the best inventory availability?

A: Samtec SMM-105-02-S-D-TR provides the highest inventory with 4454 units in stock, followed by Hirose A3A-10DA-2SV(71) with 1593 units.
