ELR-02V Equivalent & Substitute Parts Reference

Part Overview

The ELR-02V is a 2-position rectangular connector receptacle housing manufactured by JST Sales America Inc. This component is part of the EL series and is designed for panel mount, snap-in applications with crimp contact termination. The part is currently active in production with 809 units in stock. Finding equivalent substitute parts is necessary when the primary part is unavailable, when supply chain optimization is required, or when design flexibility across connector families is needed while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELR-02V are identified based on the following critical parameters that determine functional and mechanical compatibility:

Position Count: Both the main part and substitute must accommodate 2 positions to maintain circuit connectivity requirements.

Pitch and Row Spacing: The 0.177" (4.50mm) row spacing is a fundamental mechanical dimension that ensures physical mating compatibility between connector housings and contact assemblies.

Contact Termination Method: Crimp termination is required to ensure compatibility with existing contact preparation and assembly processes.

Connector Type Pairing: The ELR-02V receptacle (with male pin contacts) requires a mating plug connector (with female socket contacts) for complete circuit assembly. The substitute 776427-2 is a plug housing that provides the complementary connector type.

Environmental Compliance: RoHS compliance status and MSL rating ensure the substitute meets regulatory and manufacturing environment requirements.

The identified substitute, 776427-2 (TE Connectivity Deutsch Connectors, AMPSEAL 16 series), meets these critical parameters while originating from a different manufacturer and connector family.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (ELR-02V): Recommended for applications requiring panel mount, snap-in receptacle housings within the -25°C to 90°C operating range. RoHS compliance and unlimited MSL rating support standard manufacturing and storage environments. Active product status ensures ongoing availability and supply chain stability.

Substitute Part (776427-2): Applicable when a mating plug connector is required or when the extended operating temperature range (-40°C to 125°C) is necessary for the application. ROHS3 compliance exceeds RoHS requirements. The free-hanging, in-line mounting configuration differs from the panel mount design of the primary part and must be evaluated for mechanical fit within the assembly. Both parts maintain crimp termination compatibility and 2-position, 4.50mm pitch specifications.

Compliance Considerations: Both parts carry unlimited MSL ratings, eliminating moisture sensitivity concerns during storage and handling. Both are active products with current manufacturing status, supporting long-term design stability.

Frequently Asked Questions (FAQ)

Q: Can the ELR-02V and 776427-2 be used interchangeably in the same assembly?

A: These parts are complementary rather than interchangeable. The ELR-02V is a receptacle housing (panel mount), while the 776427-2 is a plug housing (free hanging). They are designed to mate together. Direct substitution of one for the other is not possible; however, both can be used together in a complete connector assembly.

Q: What does the 0.177" (4.50mm) row spacing specification mean?

A: This dimension defines the distance between the two contact positions within the connector housing. Both the main part and substitute maintain this identical spacing, ensuring mechanical compatibility with mating connectors and contact assemblies designed for this pitch.

Q: Are there differences in mounting that affect part selection?

A: Yes. The ELR-02V is designed for panel mount, snap-in installation, while the 776427-2 is configured for free-hanging, in-line mounting. The application's mechanical requirements determine which mounting style is appropriate. These are not interchangeable in terms of installation method.

Q: Do both parts meet the same environmental standards?

A: Both parts are RoHS compliant and carry MSL 1 (Unlimited) ratings. The substitute (776427-2) carries ROHS3 certification, which is a more recent standard. The substitute also supports a wider operating temperature range (-40°C to 125°C versus -25°C to 90°C), making it suitable for more demanding thermal environments.

Q: What is the significance of crimp termination for both parts?

A: Crimp termination is the contact attachment method. Both parts use crimp termination, meaning contacts are attached by compressing a metal ferrule around a wire conductor. This ensures compatibility with standard crimp tooling and contact preparation processes used in assembly operations.

Q: How do the insulation materials differ between these parts?

A: The ELR-02V uses Polyamide (PA6), Nylon 6, while the 776427-2 uses Thermoplastic, Glass Filled material. Both materials provide adequate insulation and mechanical support for their respective applications. Material selection may affect chemical resistance and mechanical properties in specific environments.
