WPJR-02V-3-E(NN) Equivalent & Substitute Parts

Part Overview

The WPJR-02V-3-E(NN) is a 2-position rectangular connector receptacle housing manufactured by JST Sales America Inc. This component is part of the active WPJ series and serves as a housing for female socket contacts with a 5.00mm pitch. The part is RoHS compliant and rated for operating temperatures between -25°C and 85°C. Substitute parts are necessary when the original part is unavailable, when alternative insulation materials or operating temperature ranges are required, or when color-coded variants are needed for circuit identification.

Substitute Part Grouping Explanation

Substitution for the WPJR-02V-3-E(NN) is determined by the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (2), pitch (5.00mm), number of rows (1), mounting type (free hanging in-line), contact termination (crimp), and fastening type (latch lock). All substitute parts listed maintain these core electrical and mechanical specifications. Variations in insulation material (polybutylene terephthalate versus polyamide), color (blue, natural, red, or black), and operating temperature range are secondary parameters that do not prevent functional substitution when the primary parameters align. The substitute parts identified are 1241961-3, 4-1955422-3, 6-1241983-2, and 8-1241983-2, all manufactured by TE Connectivity AMP Connectors.

Engineering Selection Recommendations

All substitute parts maintain active product status and comply with RoHS requirements. The TE Connectivity AMP Connectors alternatives (1241961-3, 4-1955422-3, 6-1241983-2, and 8-1241983-2) provide extended operating temperature ranges of -40°C to 105°C compared to the original WPJR-02V-3-E(NN) range of -25°C to 85°C. Selection between substitute parts should be based on color requirements for circuit identification and insulation material compatibility with the application environment. Part 8-1241983-2 (black) and 6-1241983-2 (red) use polyamide PA6 insulation, while 4-1955422-3 uses polyamide PA66 insulation. Part 1241961-3 also uses polyamide PA6 insulation and is available in natural color. All parts are rated MSL 1 and support crimp termination with latch lock fastening.

Frequently Asked Questions (FAQ)

Q: Can I substitute the WPJR-02V-3-E(NN) with any of the listed TE Connectivity parts?

A: Yes. All listed substitute parts maintain the critical electrical and mechanical parameters: 2-position receptacle housing, female socket contacts, 5.00mm pitch, single row, free hanging in-line mounting, crimp termination, and latch lock fastening. Functional compatibility is assured across all substitutes.

Q: What is the difference between the substitute parts?

A: The primary differences are color and insulation material. Part 1241961-3 is natural color with PA6 insulation. Part 4-1955422-3 is natural color with PA66 insulation. Part 6-1241983-2 is red with PA6 insulation. Part 8-1241983-2 is black with PA6 insulation. All operate across -40°C to 105°C.

Q: Does the operating temperature difference affect substitution?

A: The substitute parts have an extended operating temperature range (-40°C to 105°C) compared to the original part (-25°C to 85°C). This wider range does not prevent substitution and may provide additional design margin for applications requiring lower or higher temperature operation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The original WPJR-02V-3-E(NN) is RoHS compliant. Substitute parts 1241961-3, 4-1955422-3, and 6-1241983-2 are ROHS3 compliant. Part 8-1241983-2 is RoHS compliant. All meet regulatory requirements.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the original and all substitutes, are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I mix colors in the same assembly?

A: Color selection is application-dependent. The available colors (blue for original, natural, red, and black for substitutes) allow for circuit identification schemes. Mixing colors is a design choice based on your assembly requirements.
