Molex 0351550310 Equivalent & Substitute Parts

Part Overview

The Molex 0351550310 is a 3-position rectangular connector receptacle housing with 2.50mm pitch, designed for free-hanging in-line applications using crimp termination. This part is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The connector accommodates female socket contacts and features a natural color housing with latch lock fastening.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0351550310 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 3 positions at 0.098" (2.50mm) pitch
• Mounting & Termination: Free-hanging in-line mounting with crimp termination
• Fastening Mechanism: Latch lock fastening
• Electrical & Environmental Compliance: ROHS3 compliance and MSL rating

Two substitute parts meet these core requirements:

XAP-03V-1 (JST Sales America Inc.) — Manufacturer-recommended substitute with active product status, matching all critical parameters including natural color housing and identical electrical specifications.

2-2338183-3 (TE Connectivity AMP Connectors) — Parametric equivalent meeting all functional requirements with active product status. Color variation (blue housing) does not affect electrical or mechanical compatibility for applications where housing color is not a design constraint.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: JST XAP-03V-1

The JST XAP-03V-1 is the manufacturer-recommended substitute with active product status and full parameter alignment including natural color housing. This part carries ROHS3 compliance and MSL 1 rating identical to the original Molex part. Inventory availability (1,000,400 pcs) ensures supply continuity for production applications.

Secondary Selection: TE 2-2338183-3

The TE Connectivity 2-2338183-3 serves as a parametric equivalent for applications where housing color is not a design-critical specification. This part maintains all functional and mechanical compatibility while offering active product status and ROHS3 compliance. The blue housing distinguishes it visually but does not affect electrical performance or mechanical fit. MSL classification differs (Not Applicable vs. 1), which may be relevant for moisture-sensitive storage or assembly environments.

Frequently Asked Questions (FAQ)

Q: Can the JST XAP-03V-1 directly replace the Molex 0351550310 in existing designs?

A: Yes. The XAP-03V-1 matches all critical parameters including connector type, position count, pitch, mounting configuration, termination method, and fastening mechanism. The natural color housing provides visual continuity with the original design.

Q: What is the significance of the color difference in the TE 2-2338183-3?

A: The blue housing in the TE part is a cosmetic variation that does not affect electrical or mechanical compatibility. Selection depends on whether housing color is specified in the application design or assembly documentation.

Q: Are contacts included with these substitute parts?

A: No. All three parts (original Molex and both substitutes) are housings only. Contacts must be sourced separately and are not included with the connector housing.

Q: What does the MSL rating difference mean for the TE substitute?

A: The Molex and JST parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. The TE part lists MSL as Not Applicable, suggesting different material composition or manufacturing process. For applications with strict moisture control requirements, the JST XAP-03V-1 is the preferred choice.

Q: Are both substitutes RoHS compliant?

A: Yes. Both the JST XAP-03V-1 and TE 2-2338183-3 are ROHS3 compliant, matching the original Molex part's environmental certification status.

Q: What is the pitch specification and why does it matter?

A: Pitch refers to the center-to-center distance between connector positions, specified as 0.098" (2.50mm). All three parts share identical pitch, ensuring mechanical and electrical compatibility with mating connectors and PCB layouts designed for the original part.
