Molex 0022011044 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0022011044 is a 4-position receptacle housing for rectangular connectors with a 0.098" (2.50mm) pitch, designed for crimp contact termination with locking ramp fastening. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. The part operates as a housing assembly without integrated contacts, requiring separate contact procurement for complete connector assembly.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022011044 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 4-position arrangement at 0.098" (2.50mm) pitch
• Mounting & Termination: Free hanging in-line mounting with crimp contact termination
• Fastening Mechanism: Locking ramp fastening system
• Compliance Standards: ROHS3 compliance and MSL rating of 1

The substitute part Molex 0050375043 meets all these criteria while offering the advantage of active product status and significantly higher inventory availability. Both parts belong to Molex rectangular connector families and maintain identical electrical and mechanical interface specifications.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0050375043 serves as the direct parametric equivalent for the obsolete 0022011044. Selection of the substitute part is supported by:

• Compliance Alignment: Both parts maintain ROHS3 compliance and identical MSL ratings, ensuring regulatory and environmental compatibility
• Active Product Status: The 0050375043 is currently in active production with substantial inventory availability (64,900 pcs), eliminating procurement risk associated with obsolete component sourcing
• Electrical & Mechanical Equivalence: All critical interface parameters—pitch, position count, termination method, and fastening mechanism—are identical between the two parts
• Series Transition: The transition from SPOX 5102 to Mini-SPOX 5264 series represents a product line evolution within Molex's rectangular connector portfolio, maintaining backward compatibility at the housing interface level

For new designs or system refreshes, the 0050375043 is the appropriate selection. For legacy system maintenance requiring exact historical matching, the 0022011044 remains available in limited inventory (994 pcs).

Frequently Asked Questions (FAQ)

Q: Can the Molex 0050375043 directly replace the 0022011044 in existing assemblies?

A: Yes. Both housings share identical pitch (0.098" / 2.50mm), position count (4), mounting type (free hanging in-line), contact termination (crimp), and fastening mechanism (locking ramp). The housings are mechanically and electrically interchangeable at the connector interface.

Q: What is the significance of the series change from SPOX 5102 to Mini-SPOX 5264?

A: The series designation reflects Molex's product line organization. Both series employ the same 2.50mm pitch and locking ramp fastening architecture. The Mini-SPOX designation indicates a refined product generation within the same connector family, not a fundamental design change affecting compatibility.

Q: Are the contact specifications identical between these two housings?

A: Both housings are supplied without integrated contacts and require separate crimp contact procurement. Contact compatibility is determined by pitch (2.50mm) and contact type (female socket), which are identical for both housings. Contacts specified for the 0022011044 are compatible with the 0050375043.

Q: Why is the 0022011044 listed as obsolete?

A: Product obsolescence reflects Molex's discontinuation of the SPOX 5102 series in favor of the active Mini-SPOX 5264 series. The 0050375043 represents the current production equivalent, offering the same functional specifications with ongoing manufacturer support and availability.

Q: What compliance certifications apply to both parts?

A: Both the 0022011044 and 0050375043 are ROHS3 compliant and carry MSL rating 1 (unlimited moisture sensitivity), indicating no special moisture handling requirements during storage or assembly. Both are REACH unaffected and classified under ECCN EAR99.
