65043-012LF Rectangular Connector Receptacle Housing - Equivalent & Substitute Parts

Part Overview

The 65043-012LF is a 50-position rectangular connector receptacle housing manufactured by Amphenol ICC (FCI) in the Mini-PV™ and Basics+ series. This component is a female socket housing with 0.100" (2.54mm) pitch spacing, designed for crimp termination in free-hanging inline applications. The part is currently active in production status with 1031 units in stock. Equivalent substitute parts are necessary when primary sourcing is unavailable, when alternative thermal or material specifications are required, or when design flexibility across multiple connector series is needed.

Substitute Part Grouping Explanation

Substitution eligibility for the 65043-012LF is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (50), pitch (0.100"/2.54mm), number of rows (2), row spacing (0.100"/2.54mm), mounting type (free hanging in-line), and contact termination method (crimp). All identified substitute parts meet these core mechanical and electrical requirements. Secondary parameters including insulation material, operating temperature range, color, and manufacturer series may vary within acceptable limits for equivalent functionality. All substitute parts maintain MSL 1 rating and RoHS compliance status.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full RoHS compliance. Selection between 65043-012LF and its equivalents depends on application-specific thermal requirements and material compatibility.

For applications operating within the -40°C to 105°C range, the 65043-012LF, 0901430050, XG5N-502, 2-86177-1, and 4-87456-0 are directly suitable. The 65239-025LF extends the upper operating temperature to 125°C and lower temperature to -65°C, making it appropriate for extended thermal environments.

The 0901430050 (Molex C-Grid III) offers the highest current inventory at 2501 units. The 2-86177-1 and 4-87456-0 (both TE Connectivity AMPMODU Mod IV series) provide equivalent specifications with glass-filled polyamide insulation. The XG5N-502 (Omron) uses glass-filled PBT insulation material.

All parts carry MSL 1 rating, indicating unlimited shelf life under standard storage conditions. RoHS compliance is confirmed across all options, with 0901430050 and XG5N-502 carrying ROHS3 certification.

Frequently Asked Questions (FAQ)

Q: Can 65043-012LF be directly replaced with 65239-025LF?

A: Yes. Both parts share identical mechanical specifications: 50 positions, 0.100" pitch, 2 rows, and crimp termination. The 65239-025LF offers extended operating temperature range (-65°C to 125°C versus -40°C to 105°C) and different insulation material (thermoplastic glass-filled versus modified polyphenylene). Verify application thermal requirements before substitution.

Q: What is the difference between Amphenol ICC and Molex 50-position connectors?

A: The 65043-012LF (Amphenol ICC) and 0901430050 (Molex) are mechanically and electrically equivalent. Primary differences are manufacturer series designation, insulation material composition (modified polyphenylene versus PPO), and operating temperature range (-40°C to 105°C versus -55°C to 105°C). Both are RoHS compliant and carry MSL 1 rating.

Q: Are TE Connectivity AMPMODU parts (2-86177-1 and 4-87456-0) interchangeable?

A: Yes. Both TE Connectivity parts share identical specifications: 50 positions, 0.100" pitch, 2 rows, crimp termination, and -65°C to 105°C operating range. Both use glass-filled polyamide insulation. Selection between them depends on availability and application requirements.

Q: What does MSL 1 rating mean for these connectors?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life under standard storage conditions. These parts do not require special moisture-controlled storage and can be stored indefinitely without desiccant packaging.

Q: Can I use XG5N-502 in place of 65043-012LF?

A: Yes. The XG5N-502 (Omron) meets all core mechanical requirements: 50 positions, 0.100" pitch, 2 rows, and crimp termination. Operating temperature range is -55°C to 105°C. Insulation material is glass-filled PBT. Verify compatibility with your specific application thermal profile.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts carry RoHS compliance certification. The 0901430050 and XG5N-502 carry ROHS3 certification, while remaining parts carry standard RoHS Compliant status.
