Molex 0022012205 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0022012205 is a 20-position rectangular connector housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line applications. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning. The housing accepts crimp-terminated contacts and features a polarizing key for correct orientation.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Molex 0022012205 is based on the following critical parameters that must remain constant:

• Connector Type: Receptacle housing only
• Position Count: Exactly 20 positions
• Pitch Specification: 0.100" (2.54mm) center-to-center spacing
• Row Configuration: Single row layout
• Mounting Style: Free-hanging in-line orientation
• Termination Method: Crimp contact interface
• Polarization: Keyed design for orientation control

The TE Connectivity AMP Connectors part 2-1375820-0 meets all these core electrical and mechanical requirements, making it a valid functional equivalent despite differences in color, series designation, and fastening mechanism.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 2-1375820-0 is the designated manufacturer-recommended substitute for the obsolete Molex 0022012205. Selection of this alternative is supported by:

• Functional Equivalence: All critical electrical and mechanical parameters align with the original specification
• Active Production Status: The TE part remains in active production, ensuring long-term availability and supply chain continuity
• Compliance Alignment: Both parts maintain equivalent RoHS and MSL certifications, suitable for equivalent application environments
• Standardized Interface: Identical pitch, position count, and crimp termination ensure direct compatibility with existing contact sets and mating connectors

The transition from the obsolete Molex housing to the active TE Connectivity equivalent presents no functional degradation for applications requiring 20-position, 2.54mm pitch receptacle housings with crimp termination.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 2-1375820-0 directly replace the Molex 0022012205 in existing assemblies?

A: Yes. Both housings accept identical crimp contacts and maintain the same 0.100" (2.54mm) pitch spacing. The polarizing key design ensures correct orientation in both cases. Physical dimensions and mounting characteristics are equivalent for free-hanging in-line applications.

Q: What is the significance of the color difference (Natural vs. White)?

A: Color is a cosmetic attribute and does not affect electrical or mechanical function. Both housings provide equivalent insulation and polarization features. Color selection may be determined by application aesthetics or internal documentation standards.

Q: Are the contacts included with either housing?

A: No. Both the Molex 0022012205 and TE Connectivity 2-1375820-0 are supplied as housings only. Crimp contacts must be sourced separately and are compatible with both housing types due to identical pitch and termination specifications.

Q: What is the difference between the Molex KK254 series and the TE Connectivity CST-100 II series?

A: These are different manufacturer series designations for functionally equivalent 2.54mm pitch rectangular connector families. Series names reflect internal product line organization but do not indicate functional differences relevant to substitution. Both series support identical pitch, position, and termination specifications.

Q: Does the TE part's specified operating temperature range (-55°C ~ 105°C) indicate superior performance?

A: The TE part provides an explicit temperature specification; the Molex part does not include this data in the available documentation. The stated range for the TE part represents the qualified operating envelope for that housing design. Compatibility is determined by the core mechanical and electrical parameters, not by temperature specification documentation.

Q: What is the impact of the different fastening types (Polarizing Key vs. Locking Ramp)?

A: Both features serve polarization and retention functions. The polarizing key on the Molex part and the locking ramp on the TE part are design variations that do not affect housing-to-contact interface compatibility. Both ensure correct mating orientation and secure contact retention.
