78211-105LF Equivalent & Substitute Parts Reference

Part Overview

The 78211-105LF is a 5-position rectangular connector receptacle housing manufactured by Amphenol ICC (FCI) in the Mini-PV™ series. This component is a female socket receptacle designed for 0.100" (2.54mm) pitch applications with crimp termination and locking ramp fastening. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters match the original specification, enabling component interchangeability in applications where the primary part is unavailable or inventory constraints exist.

Substitute Part Grouping Explanation

Substitute parts for the 78211-105LF are qualified based on matching the following critical parameters: 5-position receptacle housing, female socket contact type, 0.100" (2.54mm) pitch, single-row configuration, free-hanging in-line mounting, crimp termination, locking ramp fastening, black color, and MSL 1 rating. All three substitute parts meet these core electrical and mechanical requirements. Variations in insulation material composition and operating temperature ranges do not preclude substitution, as these represent material and performance enhancements rather than functional incompatibilities. All substitute parts maintain active product status and RoHS compliance.

Engineering Selection Recommendations

All three substitute parts are qualified for direct replacement of the 78211-105LF based on matching electrical and mechanical specifications. Selection among substitutes should be based on inventory availability and compliance requirements specific to the application.

The 102241-3 (TE Connectivity AMPMODU Mod IV series) provides the widest operating temperature range at -65°C ~ 105°C, offering enhanced performance margin for extreme low-temperature applications.

The 0901560145 (Molex C-Grid III 90156 series) extends the lower operating temperature to -55°C ~ 105°C while maintaining all core functional parameters.

The 0050579505 (Molex SL 70066 series) matches the original operating temperature range of -40°C ~ 105°C and represents the closest functional equivalent.

All parts maintain active production status and current RoHS3 compliance certification, ensuring long-term supply chain viability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 0050579505, 0901560145, and 102241-3 be used interchangeably with the 78211-105LF?

A: Yes. All three parts share identical electrical and mechanical specifications for connector type, contact configuration, pitch, mounting method, termination style, and fastening mechanism. They are functionally equivalent receptacle housings for 5-position 0.100" pitch applications.

Q: What are the differences between the substitute parts?

A: The primary differences are insulation material composition and operating temperature ranges. The 102241-3 supports -65°C minimum temperature, the 0901560145 supports -55°C minimum, and the 0050579505 matches the original -40°C minimum. These variations do not affect mechanical compatibility or electrical performance within standard operating conditions.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original 78211-105LF is RoHS Compliant, and all three substitutes are ROHS3 Compliant, meeting current regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the original and all substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Do these parts require specific contact pins or are they sold separately?

A: All parts are receptacle housings sold without contacts included. Compatible crimp contacts must be sourced separately according to the application requirements and pitch specification.

Q: Which substitute should I select if inventory is critical?

A: Inventory availability varies by distributor and time. The 102241-3 shows 13,722 pieces in stock, the 0901560145 shows 12,816 pieces, and the 0050579505 shows 7,570 pieces. Verify current availability with your supplier for time-sensitive applications.
