Molex 0022552243 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0022552243 is a 24-position rectangular connector receptacle housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line applications. This component features a black polyester glass-filled insulation body and crimp-type female socket contacts. The part is active in production and RoHS3 compliant, operating across -40°C to 105°C. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in circuit designs.

Substitute Part Grouping Explanation

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

Connector Type: Receptacle
Contact Type: Female Socket
Number of Positions: 24
Pitch: 0.100" (2.54mm)
Number of Rows: 2
Row Spacing: 0.100" (2.54mm)
Mounting Type: Free Hanging (In-Line)
Contact Termination: Crimp
Moisture Sensitivity Level: 1 (Unlimited)

All identified substitute parts match these core parameters. Variations in insulation material, color, operating temperature range, and RoHS certification status do not prevent functional substitution when these critical dimensions and electrical characteristics are identical.

Engineering Selection Recommendations

All substitute parts listed maintain active production status and comply with RoHS requirements. Selection between the Molex 0022552243 and its equivalents should be based on:

Temperature Range Considerations: The Molex 0022552243 operates from -40°C to 105°C. TE Connectivity parts (1-87977-0, 1-925370-2, 2-87456-0) extend the lower temperature limit to -65°C. Amphenol 65239-012LF extends the upper limit to 125°C, providing broader thermal coverage when required by application specifications.

Insulation Material Compatibility: Polyester, polyamide, polyphenylene, and thermoplastic insulation materials all satisfy the mechanical and electrical requirements for this connector class. Material selection should align with application environmental exposure and chemical compatibility requirements.

Color Coding: Housing color (black, green, or blue) does not affect electrical or mechanical function. Color selection is typically driven by circuit board assembly documentation or system-level identification schemes.

Compliance Status: All parts are RoHS compliant. The Molex part carries RoHS3 designation, while TE and Amphenol parts carry RoHS compliance. Both designations satisfy current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1-87977-0 directly replace Molex 0022552243 in existing designs?

A: Yes. Both parts share identical connector type, contact type, position count, pitch, row configuration, mounting method, and termination type. The TE part operates across a wider temperature range (-65°C to 105°C versus -40°C to 105°C), making it functionally compatible for direct substitution.

Q: Does housing color affect connector performance?

A: No. Housing color is a visual identifier only and does not impact electrical or mechanical performance. Black, green, and blue variants are functionally equivalent when all other parameters match.

Q: What is the significance of insulation material differences?

A: Insulation material affects mechanical durability, chemical resistance, and thermal stability. Polyester, polyamide, polyphenylene, and thermoplastic materials all meet the electrical insulation requirements for this connector class. Material selection should be based on environmental exposure conditions specific to the application.

Q: Are all substitute parts suitable for the same operating temperature range?

A: No. The Molex 0022552243 operates from -40°C to 105°C. TE parts operate from -65°C to 105°C, and Amphenol 65239-012LF operates from -65°C to 125°C. Verify that the selected substitute meets the minimum and maximum temperature requirements of your application.

Q: Do RoHS3 and RoHS compliance differences affect substitution?

A: Both RoHS3 and RoHS compliance satisfy current regulatory requirements. RoHS3 represents the current standard, while RoHS compliance indicates earlier certification. Either designation is acceptable for new designs and production.

Q: Are contacts included with these connector housings?

A: No. All listed parts are housings only. Contacts must be sourced separately and are not included in the package.
