ELR-03V Equivalent & Substitute Parts Reference

Part Overview

The ELR-03V is a 3-position rectangular connector receptacle housing manufactured by JST Sales America Inc. as part of the EL series. This component serves as the female housing interface in rectangular connector assemblies, designed for applications requiring reliable mating with corresponding plug housings. The part is currently in active production status with 1,018 units available in inventory.

Substitute parts are identified when they maintain functional equivalence across critical electrical and mechanical parameters, including connector type, number of positions, pitch specification, contact termination method, and operating temperature range. Alternative sources become necessary due to supply chain considerations, inventory availability, or design standardization requirements.

Key Parameters

Substitute Part Grouping Explanation

The substitute part 1-480701-0 (TE Connectivity AMP Connectors, Universal MATE-N-LOK series) is identified as functionally equivalent based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle housing
• Number of positions: 3
• Number of rows: 1
• Contact termination method: Crimp
• Insulation material: Polyamide (PA), Nylon
• RoHS compliance: Both parts meet regulatory requirements

Substitution Basis: Both housings accommodate 3-position crimp-terminated contacts in a single-row configuration with polyamide insulation. The receptacle connector type and crimp termination method ensure mechanical and electrical compatibility with standard contact sets designed for this connector class.

Parameter Comparison

Engineering Selection Recommendations

Primary Part (ELR-03V): Select the ELR-03V when the application requires free-hanging in-line mounting configuration with latch holder fastening. This part is RoHS compliant and suitable for operating environments within the -25°C to 90°C range.

Substitute Part (1-480701-0): The 1-480701-0 is suitable as an alternative when panel mount or snap-in mounting is acceptable for the application design. This part offers an extended operating temperature range (-55°C to 105°C) and higher inventory availability (3,600 units). Both parts meet RoHS regulatory requirements; the substitute achieves ROHS3 compliance status.

Selection between these parts depends on mechanical mounting requirements and thermal operating conditions specific to the end application. Both parts maintain equivalent electrical performance for 3-position crimp-terminated contact assemblies.

Frequently Asked Questions (FAQ)

Q: Can the 1-480701-0 directly replace the ELR-03V in existing designs?

A: Electrical compatibility is maintained for 3-position crimp-terminated contacts. However, mechanical mounting differences exist: the ELR-03V uses free-hanging in-line mounting with latch holder fastening, while the 1-480701-0 features panel mount and snap-in mounting with locking ramp fastening. Design review is required to confirm mounting compatibility.

Q: What are the key differences in operating temperature specifications?

A: The ELR-03V operates from -25°C to 90°C. The 1-480701-0 extends this range to -55°C to 105°C. Selection depends on the thermal requirements of the specific application environment.

Q: Are both parts RoHS compliant?

A: Yes. The ELR-03V is RoHS compliant. The 1-480701-0 achieves ROHS3 compliance, representing a higher compliance standard.

Q: Do these housings include contacts?

A: No. Both the ELR-03V and 1-480701-0 are housings only. Contacts must be sourced separately and crimped into the housing according to manufacturer specifications.

Q: What is the significance of the different fastening types?

A: The ELR-03V uses a latch holder fastening mechanism, while the 1-480701-0 uses a locking ramp. These represent different mechanical retention methods for mating connector pairs. The choice affects the mating force and disconnection procedure in the application.
