Molex 0022012045 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0022012045 is a 4-position rectangular connector housing with 0.100" (2.54mm) pitch, designed for free-hanging in-line applications. This component is part of the KK254 series and features a polarizing key for proper orientation. The part is classified as obsolete, making identification of suitable substitutes essential for ongoing production and maintenance applications. The housing accepts crimp-terminated contacts and uses a locking ramp fastening mechanism.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022012045 is determined by strict equivalence across the following critical parameters:

• Number of positions: 4
• Pitch specification: 0.100" (2.54mm)
• Connector type: Receptacle
• Contact type: Non-gendered
• Number of rows: 1
• Mounting type: Free hanging (in-line)
• Contact termination: Crimp
• Fastening type: Locking ramp
• Polarizing key feature: Present

The substitute part Molex 0022013047 meets all these criteria. The primary difference is the housing color (natural versus white) and series designation (6471 versus 2695), which do not affect electrical or mechanical compatibility. The substitute part is active in production with significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022013047 is the direct substitute for the obsolete Molex 0022012045. Both parts maintain identical electrical and mechanical specifications across all critical parameters. The substitute part is currently in active production status with substantially higher inventory availability (125,648 units versus 938 units).

Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage protocols. The substitute part provides documented operating temperature specifications (-40°C to 105°C), which aligns with standard industrial connector performance ranges.

The housing color difference (white versus natural) is a cosmetic variation that does not affect functional performance or compatibility with mating connectors or contact assemblies.

Frequently Asked Questions (FAQ)

Q: Can Molex 0022013047 directly replace Molex 0022012045 in existing assemblies?

A: Yes. Both parts are electrically and mechanically equivalent across all functional parameters. The housing color difference does not affect performance or compatibility.

Q: What is the significance of the series designation change (6471 to 2695)?

A: Series designations reflect internal Molex product line organization. The functional specifications remain identical, and the parts are fully interchangeable.

Q: Are there any compliance or certification differences between the two parts?

A: No. Both parts maintain ROHS3 compliance, MSL 1 rating, and REACH unaffected status. Regulatory compliance is equivalent.

Q: Why is the main part listed as obsolete?

A: Molex has transitioned the natural-colored housing variant to obsolete status. The white-colored variant (0022013047) remains in active production and serves the same functional requirements.

Q: Does the housing color affect electrical performance?

A: No. Housing color is a cosmetic specification. Electrical and mechanical performance is identical between natural and white variants.

Q: What is the contact compatibility for these housings?

A: Both housings accept the same crimp-terminated contacts designed for 0.100" (2.54mm) pitch KK254 series connectors. Contacts are not included with the housing.
