Molex 0347960402 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0347960402 is a 4-position rectangular connector receptacle housing with 4.60mm pitch, designed for free-hanging in-line applications using crimp termination. This part is classified as obsolete, making identification of active equivalent alternatives essential for ongoing production and maintenance requirements. The natural color housing is compatible with the MX150 34796 series connector system. Substitute parts maintain identical electrical and mechanical specifications while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0347960402 is determined by strict equivalence across the following critical parameters:

Connector Type & Contact Configuration: All substitutes maintain receptacle housing with female socket contacts
Position Count & Pitch: All substitutes provide 4-position configuration at 0.138" (4.60mm) pitch
Mounting & Termination: All substitutes use free-hanging in-line mounting with crimp termination and latch holder fastening
Compliance & Environmental: All substitutes maintain ROHS3 compliance and MSL 1 rating

The five identified substitute parts (0334710402, 0334710407, 0334710463, 0334710464, 0334710465) are all members of the MX150 33471 series and share identical electrical and mechanical interfaces with the original part. The primary distinction is color (gray vs. natural) and product status (active vs. obsolete), with no functional impact on connector performance or compatibility.

Engineering Selection Recommendations

All five substitute parts are functionally equivalent to the Molex 0347960402 based on identical electrical and mechanical parameters. Selection among substitutes should prioritize the following criteria:

Product Status: All substitute parts maintain active product status, ensuring long-term availability and supply chain continuity compared to the obsolete original part.

Compliance Requirements: Parts 0334710402, 0334710407, and 0334710464 carry REACH Unaffected status. Parts 0334710463 and 0334710465 carry REACH Affected status. Selection depends on regulatory requirements for the end application.

Inventory Availability: Current stock levels range from 1,259 to 2,461 units across the substitute options, with 0334710402 offering the highest availability at 2,461 pieces.

Color Consideration: The original part features natural color housing, while all substitutes are gray. This distinction is cosmetic and does not affect electrical or mechanical performance. Color selection should be based on assembly or identification requirements.

Frequently Asked Questions (FAQ)

Q: Are all substitute parts electrically and mechanically compatible with the original 0347960402?

A: Yes. All five substitute parts maintain identical connector type, contact configuration, position count, pitch, mounting method, and termination type. They are direct functional equivalents.

Q: Why is the original part obsolete while substitutes are active?

A: The Molex 0347960402 has been discontinued, but the MX150 33471 series substitutes remain in active production. This transition ensures continued availability of the same connector interface.

Q: Does the color difference between natural and gray affect performance?

A: No. Color is a cosmetic attribute only. The gray substitute parts provide identical electrical and mechanical performance to the natural original part.

Q: What is the significance of REACH Affected vs. REACH Unaffected status?

A: REACH Affected status indicates the part contains substances of concern under EU REACH regulations. Selection between REACH Affected and REACH Unaffected parts depends on the regulatory requirements of the end application and target markets.

Q: Can I mix substitute parts in the same assembly?

A: Yes. All substitute parts are interchangeable based on identical electrical and mechanical specifications. Mixed usage within a single assembly presents no compatibility issues.

Q: Are contacts included with these connector housings?

A: No. All parts, including the original and substitutes, are housings only. Contacts must be sourced separately and crimped into the housing.
