Molex 0351551002 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0351551002 is a 10-position receptacle housing for rectangular connectors with 0.098" (2.50mm) pitch, designed for free-hanging in-line applications using crimp termination. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing procurement and system maintenance. The housing accommodates female socket contacts and features a latch lock fastening mechanism. Contacts are supplied separately and must be selected to match the housing specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Molex 0351551002 is determined by strict equivalence across the following critical parameters:

• Connector type (receptacle)
• Contact type (female socket)
• Number of positions (10)
• Pitch specification (0.098" / 2.50mm)
• Number of rows (1)
• Mounting configuration (free hanging in-line)
• Contact termination method (crimp)
• Fastening mechanism (latch lock)

Parts meeting all these criteria are classified as parametric equivalents. Variations in color, insulation material, operating temperature range, or series designation do not affect functional interchangeability when these core parameters remain constant. All identified substitutes maintain ROHS3 compliance and MSL rating 1 status.

Parameter Comparison

Engineering Selection Recommendations

Molex 0351551000 is the primary parametric equivalent within the same manufacturer series (35155). This part maintains active product status with higher inventory availability (14,221 units) compared to the obsolete 0351551002. The natural color housing and polyester insulation material provide direct functional substitution. Operating temperature range of -40°C to 105°C covers standard industrial applications.

Molex 0511031000 represents an alternative from the Mini-Lock 51103 series. This part carries a Last Time Buy status, indicating limited future availability. The white housing and PBTP insulation material differ from the original, but all critical electrical and mechanical parameters remain equivalent. Operating temperature specification matches the 0351551000 variant.

JST XAP-10V-1 is a cross-manufacturer substitute from JST Sales America Inc. within the XA series. This part maintains active status with substantial inventory (62,702 units). The natural color housing and PA66/Nylon 6/6 insulation material are functionally equivalent. The operating temperature range (-25°C to 85°C) is narrower than Molex alternatives and should be evaluated against application requirements.

All three substitutes maintain ROHS3 compliance and MSL rating 1 status, ensuring regulatory and environmental compatibility with the original part.

Frequently Asked Questions (FAQ)

Q: Can Molex 0351551000 be used as a direct replacement for the obsolete 0351551002?

A: Yes. Both parts share identical electrical and mechanical specifications: 10-position receptacle housing, 0.098" pitch, female socket contacts, crimp termination, and latch lock fastening. The color difference (natural vs. red) and insulation material variation (polyester vs. unspecified) do not affect functional interchangeability.

Q: What is the difference between the Molex and JST substitute options?

A: All three parts meet the core substitution criteria. Molex 0351551000 and 0351551000 are from the same manufacturer with active or last-time-buy status. JST XAP-10V-1 is a cross-manufacturer alternative with active status and higher inventory. The primary technical difference is the operating temperature range: Molex parts support -40°C to 105°C, while JST supports -25°C to 85°C. Select based on application temperature requirements and preferred supplier.

Q: Does the color difference between substitutes affect compatibility?

A: No. Color is a cosmetic parameter that does not affect electrical or mechanical function. The red (0351551002), natural (0351551000, XAP-10V-1), and white (0511031000) housings are functionally equivalent when all other parameters match.

Q: Are contacts included with these housing parts?

A: No. All listed parts are housings only. Contacts must be procured separately and must match the 10-position, 0.098" pitch, female socket, crimp termination specification.

Q: What does "Last Time Buy" status mean for the Molex 0511031000?

A: Last Time Buy indicates that the manufacturer has announced end-of-life for this part. Existing inventory may be available, but future production is not planned. For long-term applications, Molex 0351551000 or JST XAP-10V-1 are recommended as they maintain active product status.

Q: Can I mix contacts from different manufacturers with these housings?

A: Contacts must be compatible with the specific housing series and pitch specification. Verify contact part numbers against the housing manufacturer's compatibility documentation before assembly.
