Molex 0351551202 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0351551202 is a 12-position receptacle housing for rectangular connectors with 2.50mm pitch, designed for crimp termination in free-hanging inline applications. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing procurement and system maintenance. The housing accommodates female socket contacts and features a latch lock fastening mechanism. Substitute parts must maintain electrical and mechanical compatibility across the same connector interface specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0351551202 is determined by strict equivalence across the following parameters: connector type (receptacle), contact type (female socket), number of positions (12), pitch (2.50mm), number of rows (1), mounting type (free hanging inline), contact termination method (crimp), and fastening mechanism (latch lock). Two substitute parts meet these criteria:

Molex 0351551200 - Manufacturer-recommended substitute within the same 35155 series. Maintains identical electrical and mechanical specifications with active product status and higher inventory availability.

Hirose Electric HNC1-2.5S-12 - Cross-manufacturer substitute from the HNC series. Meets all core substitution parameters while offering alternative sourcing from a different manufacturer.

Parameter Comparison

Engineering Selection Recommendations

Molex 0351551200 is the primary substitute for the obsolete 0351551202. Both parts share identical series designation (35155), equivalent electrical and mechanical specifications, and ROHS3 compliance. The 0351551200 maintains active product status with significantly higher inventory availability (3444 units), ensuring supply chain continuity. Selection of this part eliminates cross-manufacturer compatibility considerations.

Hirose Electric HNC1-2.5S-12 serves as an alternative cross-manufacturer substitute when Molex supply is constrained. This part maintains all core substitution parameters and active product status. RoHS compliance is confirmed, though certification level differs from the Molex alternative. Inventory availability is adequate (1064 units). Cross-manufacturer substitution requires verification that mating connector interfaces are compatible with Hirose HNC series receptacles.

Both substitute parts carry MSL rating of 1 (unlimited moisture sensitivity), matching the original part specification and eliminating moisture-related handling constraints.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0351551200 directly replace the obsolete 0351551202?

A: Yes. Both parts are 12-position receptacle housings with 2.50mm pitch, crimp termination, and latch lock fastening. Electrical and mechanical compatibility is maintained across all specified parameters. The primary difference is product status (active versus obsolete) and housing color (natural versus red).

Q: What are the key differences between the Molex and Hirose substitutes?

A: Both maintain identical connector specifications (12 positions, 2.50mm pitch, receptacle type, crimp termination, latch lock fastening). Differences include manufacturer, housing color (natural for Molex, black for Hirose), insulation material composition, and operating temperature ranges. Mating connector compatibility must be verified when selecting the Hirose alternative.

Q: Are there packaging considerations when selecting a substitute?

A: The Molex 0351551200 is supplied in bulk packaging. The Hirose HNC1-2.5S-12 is also supplied in bulk packaging. Packaging format does not affect electrical or mechanical compatibility; selection should be based on procurement requirements and supply availability.

Q: Do all substitute parts meet RoHS compliance requirements?

A: Yes. The Molex 0351551200 is ROHS3 compliant. The Hirose HNC1-2.5S-12 is RoHS compliant. Both parts satisfy RoHS regulatory requirements for lead-free manufacturing and restricted substance limitations.

Q: What is the significance of the MSL rating for these connectors?

A: All three parts carry MSL rating 1 (unlimited), indicating no moisture sensitivity constraints during storage or handling. Standard storage conditions apply without special desiccant or humidity control requirements.
