Molex 0872631693 Equivalent & Substitute Parts

Part Overview

The Molex 0872631693 is a 16-position receptacle connector with 0.079" (2.00mm) pitch, designed for surface mount applications in board-to-board or cable interconnect configurations. This connector features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 105°C. The part is active in production with 817 units in current inventory.

Equivalent and substitute parts are identified when design requirements permit variations in electrical ratings, insulation materials, contact geometry, or packaging formats while maintaining core functional compatibility for 16-position, 2.00mm pitch receptacle applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

• Connector geometry: 16 positions, 2.00mm pitch, 2-row configuration, receptacle type, female socket contacts
• Mounting and termination: Surface mount with solder termination
• Fastening mechanism: Push-pull fastening
• Electrical baseline: Minimum 1A current rating and 125VAC voltage rating
• Environmental compliance: UL94 V-0 flammability, ROHS3 compliance, MSL 1

Substitute parts may vary in:

• Contact finish thickness (mating and post)
• Insulation material and color
• Insulation height
• Contact shape and material composition
• Packaging format (Tape & Reel, Tube, Cut Tape)
• Operating temperature range (if equal to or exceeding -55°C to 105°C)
• Current and voltage ratings (if equal to or exceeding base ratings)

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and ROHS3 compliance with MSL 1 rating, ensuring regulatory and environmental compatibility with the Molex 0872631693.

Hirose A3-16DA-2SV(71) and A3A-16DA-2SV(71): These parts provide direct functional substitution with identical 16-position, 2.00mm pitch geometry and push-pull fastening. Both operate at -55°C to 85°C, which is within the lower end of the original operating range. Voltage rating increases to 200VAC. The A3A variant includes board guide features. Insulation material transitions from thermoplastic to polyphenylene sulfide (PPS), with square contact geometry replacing circular contacts. Available in tube packaging.

Samtec Tiger Eye™ SMM Series (SMM-108-02-S-D-K-TR, SMM-108-02-S-D-LC, SMM-108-02-S-D-P-TR, SMM-108-02-S-D-TR): These parts exceed electrical specifications with 3.2A per contact current rating and 350VAC voltage rating. Operating temperature extends to 125°C, exceeding the original -55°C to 105°C range. Insulation material is liquid crystal polymer (LCP) with square contact geometry. Contact material is beryllium copper. Packaging options include Tape & Reel (TR), Tube (LC), and Cut Tape (CT). The SMM-108-02-S-D-K-TR and SMM-108-02-S-D-P-TR variants include pick-and-place features; SMM-108-02-S-D-LC includes board lock features.

Frequently Asked Questions (FAQ)

Q: Can I substitute the Molex 0872631693 with any of these parts directly?

A: Yes, all listed parts are functionally compatible substitutes. They maintain the same 16-position, 2.00mm pitch, 2-row receptacle configuration with female socket contacts, push-pull fastening, and solder termination. Mechanical and electrical compatibility is preserved across all variants.

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

A: Hirose A3 series parts operate at -55°C to 85°C with 200VAC rating and use polyphenylene sulfide (PPS) insulation. Samtec SMM series parts operate at -55°C to 125°C with 350VAC rating and use liquid crystal polymer (LCP) insulation. Samtec parts also provide higher current capacity at 3.2A per contact versus 1A. Both maintain identical pitch and position geometry.

Q: Does packaging format affect electrical or mechanical performance?

A: No. Tape & Reel (TR), Tube, and Cut Tape (CT) packaging formats are logistics and assembly considerations only. They do not alter connector electrical specifications, mating characteristics, or reliability. Selection depends on manufacturing process requirements and inventory management.

Q: Are there temperature range limitations I should consider?

A: The Hirose A3 series operates to 85°C maximum, which is 20°C below the original Molex specification of 105°C. If your application requires operation above 85°C, use Samtec SMM series parts, which operate to 125°C. For applications below 85°C, both options are suitable.

Q: What is the difference between A3-16DA-2SV(71) and A3A-16DA-2SV(71)?

A: Both are identical 16-position, 2.00mm pitch receptacles from Hirose. The A3A variant includes board guide features for improved alignment during assembly. Electrical and mechanical specifications are otherwise identical.

Q: Which Samtec variant should I select?

A: All Samtec SMM-108 variants listed share identical electrical and mechanical specifications. Selection depends on packaging preference: SMM-108-02-S-D-K-TR and SMM-108-02-S-D-P-TR offer Tape & Reel with pick-and-place features; SMM-108-02-S-D-LC offers Tube with board lock features; SMM-108-02-S-D-TR offers Cut Tape without additional features.

Q: Are all parts RoHS3 compliant?

A: Yes. The Molex 0872631693 and all listed substitutes are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), ensuring compatibility with lead-free assembly processes and environmental regulations.
