Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Molex 0878311629 are qualified based on strict alignment with the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Configuration: 16 positions in 2-row arrangement
• Pitch Specification: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Through-hole solder termination
• Shrouding: 4-wall shrouded design
• Electrical Ratings: Minimum 2A current and 125V voltage capability
• Environmental Compliance: ROHS3 compliance and MSL 1 rating

The identified substitutes—Amphenol ICC (FCI) 10075025-G01-16ULF and Samtec Inc. LTMM-108-02-T-D—meet these core criteria and are classified as manufacturer-recommended alternatives within the rectangular connector header category.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and comply with ROHS3 or equivalent RoHS standards, ensuring regulatory alignment for current and future applications. The Molex 0878311629 and Samtec LTMM-108-02-T-D both specify operating temperature ranges of -55°C to 105°C, supporting extended thermal environments. The Amphenol ICC 10075025-G01-16ULF provides elevated voltage rating (200V versus 125V) and enhanced contact finish options (GXT™ gold), offering additional margin for high-voltage or high-reliability applications. All three parts carry MSL 1 rating, eliminating moisture sensitivity constraints during storage and handling. Selection should prioritize inventory availability, series compatibility with existing connector ecosystems, and specific contact finish requirements for the intended application environment.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 10075025-G01-16ULF be used as a direct replacement for the Molex 0878311629?

A: Yes, within the constraints of mechanical and electrical compatibility. Both connectors share identical pitch (2.00mm), position count (16), row configuration (2), mounting type (through-hole), and shrouding (4-wall). The Amphenol part provides higher voltage rating (200V) and alternative contact finish (GXT™ gold), making it suitable for equivalent or more demanding applications. Physical dimensions vary slightly; verify PCB layout compatibility before implementation.

Q: What are the key differences in insulation material between these three parts?

A: The Molex 0878311629 uses glass-filled polyamide (nylon), the Amphenol ICC part uses thermoplastic, and the Samtec part uses liquid crystal polymer (LCP). These materials differ in thermal stability, dimensional tolerance, and chemical resistance. LCP offers superior dimensional stability and lower moisture absorption. Material selection should align with PCB processing temperatures and environmental exposure conditions.

Q: Are there any compatibility concerns with mating connectors?

A: All three headers are designed for 2.00mm pitch mating with compatible receptacle connectors. Verify that existing receptacle connectors in your design are qualified for the specific header series (Milli-Grid 87831, Minitek® 2.00mm, or Flex Stack LTMM). Cross-series mating is not recommended without explicit manufacturer validation.

Q: Which substitute part is recommended for automotive applications?

A: The Molex 0878311629 explicitly lists automotive applications. Both substitute parts are active-status components with ROHS3 compliance suitable for automotive environments. The Samtec LTMM-108-02-T-D shares the same operating temperature range (-55°C to 105°C) as the Molex part, providing thermal equivalence for automotive thermal cycling requirements.

Q: What is the significance of the contact finish differences?

A: The Molex and Amphenol parts feature gold-plated mating contacts (30.0µin thickness), providing superior corrosion resistance and contact reliability. The Samtec part uses tin finish on mating contacts, suitable for standard applications but offering less corrosion protection in harsh environments. Gold finish is preferred for high-reliability, long-term storage, or corrosive environments.

Q: How do the insulation heights affect PCB layout?

A: Insulation heights vary: Molex 0.252" (6.40mm), Amphenol 0.220" (5.60mm), and Samtec 0.190" (4.83mm). Lower insulation height reduces overall connector profile, beneficial for space-constrained designs. Verify clearance requirements for adjacent components and connector retention features before selecting based on height alone.
