78211-010LF Equivalent & Substitute Parts

Part Overview

The 78211-010LF is a 10-position rectangular connector housing manufactured by Amphenol ICC (FCI) in the Mini-PV™ series. This receptacle housing is designed for 0.100" (2.54mm) pitch applications with crimp-style female socket contacts. The part is currently active in production with full RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector interface, ensuring functional interchangeability in applications requiring 10-position, 2.54mm pitch receptacle housings.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 78211-010LF is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: Exactly 10 positions at 0.100" (2.54mm) spacing
• Row Configuration: Single-row layout
• Mounting & Termination: Free hanging in-line mounting with crimp termination
• Polarization: Presence of polarizing key feature
• Color & Material: Black housing with polyphenylene-based insulation

The substitute part 0901230110 (Molex C-Grid III 90123 series) meets all these criteria, maintaining full mechanical and electrical compatibility with the 78211-010LF in applications requiring 10-position, 2.54mm pitch receptacle housings.

Parameter Comparison

Engineering Selection Recommendations

Both the 78211-010LF and 0901230110 are active production parts with full regulatory compliance. The 78211-010LF operates across -40°C to 105°C, while the 0901230110 extends the lower temperature limit to -55°C. Selection between these parts should be based on application temperature requirements and supply chain availability. Both parts carry RoHS compliance (RoHS Compliant and ROHS3 Compliant respectively) and unlimited moisture sensitivity rating, making them suitable for standard industrial and commercial applications. The presence of polarizing keys in both housings ensures correct mating orientation and reduces assembly errors.

Frequently Asked Questions (FAQ)

Q: Can the 0901230110 directly replace the 78211-010LF in existing designs?

A: Yes. Both parts are 10-position, 2.54mm pitch receptacle housings with identical mechanical interfaces, polarizing key features, and crimp termination. They are functionally interchangeable for connector housing applications.

Q: What is the difference in operating temperature ranges?

A: The 78211-010LF operates from -40°C to 105°C, while the 0901230110 operates from -55°C to 105°C. The Molex part provides extended low-temperature capability. For applications within the -40°C to 105°C range, both parts perform identically.

Q: Are both parts RoHS compliant?

A: Yes. The 78211-010LF is RoHS Compliant, and the 0901230110 is ROHS3 Compliant. Both meet current RoHS requirements for lead-free manufacturing.

Q: Do these housings include contacts?

A: No. Both the 78211-010LF and 0901230110 are housings only. Contacts must be sourced separately and are not included with these parts.

Q: What is the significance of the polarizing key feature?

A: The polarizing key prevents incorrect mating orientation between the plug and receptacle, ensuring proper electrical connection and reducing assembly errors in production environments.

Q: Are there any differences in insulation material between these parts?

A: The 78211-010LF uses Polyphenylene Modified insulation, while the 0901230110 uses Polyphenylene Oxide (PPO). Both materials provide equivalent electrical and mechanical performance for this connector class.
