Molex 0022012156 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0022012156 is a 15-position receptacle housing for rectangular connectors with a 0.100" (2.54mm) pitch, designed for free-hanging in-line applications using crimp termination. This part is classified as obsolete, making identification of suitable substitutes essential for ongoing system support and component procurement. The natural color housing is part of the KK254 and 6471 series. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct compatibility without circuit redesign or connector rework.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0022012156 is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Must be receptacle housing with exactly 15 positions
• Pitch & Row Configuration: Must maintain 0.100" (2.54mm) pitch in single-row layout
• Mounting & Termination: Must support free-hanging in-line mounting with crimp contact termination
• Contact Interface: Must use non-gendered contact design
• Compliance: Must maintain ROHS3 compliance and MSL 1 rating

The substitute part Molex 0022012151 meets all these criteria. The primary difference is housing color (white versus natural) and series designation (2695 versus 6471), which do not affect electrical or mechanical compatibility. Both parts share the same base product number (002201) and are manufactured by Molex using identical connector architecture.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0022012151 is the direct substitute for the obsolete Molex 0022012156. Both parts are manufactured by Molex, share identical electrical and mechanical specifications, and maintain equivalent ROHS3 compliance and MSL 1 ratings. The 0022012151 is currently in active production with substantial inventory availability (11,676 pcs), whereas the 0022012156 is obsolete with limited stock (667 pcs).

The housing color difference (white versus natural) is a cosmetic variation that does not affect connector function, mating performance, or electrical characteristics. The 0022012151 provides superior long-term supply chain security due to its active product status and higher inventory levels. For new designs or component replenishment, the 0022012151 is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0022012151 directly replace the 0022012156 in existing assemblies?

A: Yes. Both parts are 15-position receptacle housings with 0.100" (2.54mm) pitch, identical mounting type, and crimp termination. The housings are mechanically and electrically interchangeable. The only difference is housing color.

Q: Does the white color of the 0022012151 affect connector performance compared to the natural color of the 0022012156?

A: No. Housing color is a cosmetic attribute and does not influence electrical performance, mating force, contact retention, or environmental protection.

Q: Are both parts compatible with the same contact pins and mating plugs?

A: Yes. Both housings use identical contact architecture and pitch. Contacts and mating plugs designed for the 0022012156 are fully compatible with the 0022012151.

Q: What is the significance of the different series designations (6471 versus 2695)?

A: Series designations reflect internal Molex product line organization and manufacturing batches. Both series are part of the KK254 connector family and share identical specifications for this housing configuration.

Q: Why is the 0022012156 listed as obsolete?

A: Molex has transitioned production to the 0022012151, which is the active equivalent. The natural color variant (0022012156) is no longer manufactured, making the white variant (0022012151) the current standard offering.

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

A: No. Both parts are ROHS3 compliant with MSL 1 rating. The 0022012151 provides documented operating temperature range (-40°C ~ 105°C) and insulation material specification (Polyamide/Nylon), which are standard for this connector family.
