Molex 0022552541 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0022552541 is a 54-position rectangular connector receptacle housing designed for 0.100" (2.54mm) pitch applications. This component serves as the housing structure for female socket contacts in two-row configurations, commonly used in industrial and commercial electronic assemblies. The part is actively manufactured and maintains full RoHS3 compliance with unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when primary inventory is unavailable or when design flexibility permits cross-manufacturer compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022552541 is determined by strict alignment of the following critical parameters:

Connector type (Receptacle)
Contact type (Female Socket)
Position count (54)
Pitch specification (0.100" / 2.54mm)
Row configuration (2 rows)
Row spacing (0.100" / 2.54mm)
Mounting method (Free Hanging In-Line)
Termination style (Crimp)
Color (Black)
Operating temperature range (-40°C to 105°C)

The Amphenol ICC (FCI) part number 65043-010LF meets all these parameters and qualifies as a parametric equivalent. Both parts are active products with identical functional specifications for housing structure and contact accommodation.

Engineering Selection Recommendations

Both the Molex 0022552541 and Amphenol ICC 65043-010LF are active products with equivalent functional specifications. Selection between these parts may be based on:

Inventory availability and lead time requirements
Supply chain preferences and established vendor relationships
RoHS compliance status (both meet regulatory requirements; Molex carries RoHS3 designation while Amphenol ICC carries RoHS Compliant designation)
REACH regulatory status (Molex is REACH Unaffected; Amphenol ICC is REACH Affected)
Organizational procurement policies regarding multi-source qualification

Both parts maintain identical operating temperature ranges, moisture sensitivity ratings, and mechanical specifications required for direct functional substitution in 54-position, 2.54mm pitch connector applications.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 65043-010LF directly replace the Molex 0022552541 in existing designs?

A: Yes. Both parts share identical specifications for connector type, position count, pitch, row configuration, mounting method, and operating temperature range. The housing structures are functionally equivalent for contact accommodation and mechanical interface.

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

A: Yes. The Molex 0022552541 uses Polyester Glass Filled insulation, while the Amphenol ICC 65043-010LF uses Polyphenylene Modified insulation. Both materials support the specified operating temperature range and electrical requirements.

Q: What is the significance of the different REACH statuses?

A: The Molex part is REACH Unaffected, indicating it does not contain substances of very high concern (SVHC) listed under REACH regulations. The Amphenol ICC part is REACH Affected, meaning it may contain listed substances but remains compliant with REACH requirements. Selection depends on end-use application and regional regulatory requirements.

Q: Do both parts require the same contact specifications?

A: Yes. Both housings are designed for crimp-terminated female socket contacts at 0.100" (2.54mm) pitch. Contact compatibility is determined by pitch and termination method, which are identical across both parts.

Q: Are there packaging or inventory considerations for selection?

A: Both parts are supplied in bulk packaging. Current inventory levels differ (Molex: 714 pcs; Amphenol ICC: 868 pcs), which may influence procurement decisions based on immediate availability requirements.
