Molex 0511031300 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The Molex 0511031300 is a 13-position receptacle housing for rectangular connectors with a 2.50mm pitch, designed for free-hanging in-line applications. This component is part of the Mini-Lock 51103 series and is actively manufactured. Alternative equivalent parts may be required due to supply chain considerations, regional availability, or specific application requirements where substitute housings meet identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0511031300 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 13 positions at 0.098" (2.50mm) pitch
• Mechanical Interface: Single-row, free-hanging in-line mounting with crimp termination and latch lock fastening
• Electrical & Environmental Compliance: RoHS3 compliance and MSL 1 rating

The JST Sales America Inc. XAP-13V-1 meets these core substitution criteria. Both parts are functionally equivalent housings designed to accept the same contact pitch and position configuration, with identical connector type and mounting characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0511031300 and JST XAP-13V-1 are actively manufactured products with full RoHS3 compliance and MSL 1 ratings, making them suitable for equivalent selection in applications requiring 13-position receptacle housings at 2.50mm pitch.

The primary distinction between these parts is the operating temperature range. The Molex 0511031300 supports -40°C to 105°C, while the JST XAP-13V-1 operates within -25°C to 85°C. Selection should be based on the specific thermal requirements of the application. Additionally, the insulation materials differ: Molex uses PBTP while JST uses PA66 nylon. Both materials are suitable for standard industrial applications with equivalent electrical properties at the specified pitch and position configuration.

Frequently Asked Questions (FAQ)

Q: Can the JST XAP-13V-1 be used as a direct replacement for the Molex 0511031300?

A: Yes, for applications operating within the -25°C to 85°C temperature range. Both housings are 13-position receptacles with 2.50mm pitch, identical mounting type, and equivalent crimp termination with latch lock fastening. Verify your application's thermal requirements before substitution.

Q: What are the key compatibility factors between these two housings?

A: Compatibility is determined by connector type (receptacle), contact configuration (female socket), position count (13), pitch (2.50mm), mounting style (free-hanging in-line), and termination method (crimp with latch lock). Both parts meet these specifications identically.

Q: Are there differences in contact compatibility?

A: Both housings accept crimp contacts designed for 2.50mm pitch applications. Contacts are not included with either housing. Verify that replacement contacts are specified for the appropriate pitch and contact type.

Q: How do the insulation materials affect performance?

A: PBTP (Molex) and PA66 nylon (JST) are both suitable for standard rectangular connector applications. Material selection does not affect electrical performance at the specified pitch and position configuration. Application-specific environmental factors should guide material selection.

Q: What is the significance of the operating temperature difference?

A: The Molex 0511031300 supports extended low-temperature operation (-40°C minimum) and higher maximum temperature (105°C) compared to the JST XAP-13V-1 (-25°C to 85°C). Select based on your application's thermal environment.
