Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0872631493 are qualified based on the following critical parameters that determine functional interchangeability:

Primary Matching Criteria:

• 14 positions with 0.079" (2.00mm) pitch
• 2-row configuration with 0.079" (2.00mm) row spacing
• Surface mount receptacle with female socket contacts
• Push-pull fastening mechanism
• Gold-plated mating contacts
• Solder termination
• UL94 V-0 flammability rating
• ROHS3 compliance

Acceptable Variation Parameters:

• Operating temperature range (provided substitute parts operate at -55°C ~ 85°C or -55°C ~ 125°C, both encompassing or exceeding the main part's -55°C ~ 105°C range)
• Voltage rating (provided substitutes rated at 200VAC or 350VAC, both exceeding the main part's 125VAC requirement)
• Current rating (provided substitutes rated at 1A or 3.2A per contact, meeting or exceeding the main part's 1A requirement)
• Insulation material and color (thermoplastic, polyphenylene sulfide, or liquid crystal polymer)
• Contact finish thickness and post material (all tin-plated posts)
• Packaging format (Tape & Reel or Tube)

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts meet the core electrical and mechanical requirements for functional compatibility with the Molex 0872631493. Selection among these alternatives depends on application-specific constraints:

Hirose A3-14DA-2SV(71) and A3A-14DA-2SV(71): These parts provide direct functional equivalence with matching 1A current rating and 200VAC voltage rating. The A3A variant includes board guide features. Both operate at -55°C to 85°C, which covers the main part's operating range except for the upper 20°C margin. Tube packaging is suitable for lower-volume or manual assembly processes. Both are ROHS3 compliant with UL94 V-0 rating.

Samtec SMM-107-02-S-D-K-TR and SMM-107-02-S-D-P-TR: These Tiger Eye™ SMM series connectors provide enhanced electrical performance with 3.2A per contact current rating and 350VAC voltage rating, exceeding the main part's specifications. Operating temperature extends to 125°C, providing additional thermal margin. Tape & Reel packaging supports automated assembly. Both are ROHS3 compliant with UL94 V-0 rating. The SMM-107-02-S-D-P-TR variant includes pick-and-place features.

All substitute parts carry ROHS3 compliance and UL94 V-0 flammability certification, matching the main part's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can the Hirose A3-14DA-2SV(71) be used as a direct replacement for the Molex 0872631493?

A: Yes. Both connectors share identical 14-position, 0.079" pitch configuration, surface mount receptacle design, and push-pull fastening. Electrical ratings (1A, 200VAC) exceed the main part's requirements (1A, 125VAC). The operating temperature range of -55°C to 85°C covers the main part's range except for the upper 20°C margin. Compliance certifications match.

Q: What is the difference between the Hirose A3-14DA-2SV(71) and A3A-14DA-2SV(71)?

A: Both parts are electrically and mechanically identical. The A3A variant includes board guide features. Selection depends on whether board guidance is required for your assembly process. Inventory availability differs (873 pcs vs. 8892 pcs).

Q: Are the Samtec SMM-107 series parts compatible with the Molex 0872631493?

A: Yes. The SMM-107-02-S-D-K-TR and SMM-107-02-S-D-P-TR maintain the same 14-position, 0.079" pitch, surface mount receptacle configuration. They provide enhanced electrical performance (3.2A per contact, 350VAC) and extended operating temperature (-55°C to 125°C). Both support automated assembly via Tape & Reel packaging.

Q: What is the difference between SMM-107-02-S-D-K-TR and SMM-107-02-S-D-P-TR?

A: Both parts are electrically and mechanically identical. The SMM-107-02-S-D-P-TR includes pick-and-place features for automated assembly. Selection depends on assembly process requirements. Inventory availability differs (1334 pcs vs. 3236 pcs).

Q: Does packaging format affect electrical compatibility?

A: No. Tape & Reel (TR) and Tube packaging formats do not affect electrical or mechanical compatibility. Packaging selection depends on assembly process requirements: Tape & Reel supports automated pick-and-place assembly, while Tube packaging is suitable for manual or lower-volume assembly.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance and UL94 V-0 flammability certification, matching the main part's regulatory status.

Q: Can I use a substitute part with higher voltage or current rating?

A: Yes. The Samtec SMM-107 series parts with 3.2A per contact and 350VAC ratings exceed the main part's 1A and 125VAC specifications. Higher ratings provide additional design margin and do not create compatibility issues in applications designed for the lower ratings.
