Engineering Selection Recommendations

All four substitute parts are active products with current manufacturing status. Selection among these equivalents should be based on the following factors:

Color Matching: If color specification is critical to the application, 6-1241983-2 maintains the red housing color of the original WPJR-02V-2-R(NN). The 1241961-3 and 4-1955422-3 provide natural housing, while 8-1241983-2 offers black housing.

Material Composition: The original part uses PBT glass-filled insulation material. Substitute parts employ PA6 or PA66 nylon materials. Material selection should align with application thermal and chemical exposure requirements within the specified operating temperature ranges.

Temperature Operating Range: The WPJR-02V-2-R(NN) operates from -25°C to 85°C. All substitute parts extend this range to -40°C to 105°C, providing broader thermal capability for demanding applications.

Compliance Status: All parts maintain RoHS compliance. The TE Connectivity parts 1241961-3 and 4-1955422-3 carry ROHS3 certification, representing the most current compliance standard.

Inventory Availability: 6-1241983-2 offers the highest stock level (107,019 units), followed by 1241961-3 (2,481 units) and 4-1955422-3 (1,826 units), with 8-1241983-2 at 19,062 units.

Frequently Asked Questions (FAQ)

Q: Can I substitute the WPJR-02V-2-R(NN) with any of the listed TE Connectivity parts?

A: Yes. All four TE Connectivity parts (1241961-3, 4-1955422-3, 6-1241983-2, and 8-1241983-2) are parametric equivalents that maintain identical electrical and mechanical specifications for the critical connector parameters: 2-position receptacle, 5.00mm pitch, female socket contacts, crimp termination, and latch lock fastening.

Q: Does the color difference affect electrical performance?

A: No. Color is a cosmetic parameter that does not affect electrical or mechanical function. Selection should be based on application requirements or design specifications.

Q: What is the difference between PA6 and PA66 insulation materials?

A: Both are polyamide nylon materials used in connector housings. PA66 (nylon 6/6) typically offers slightly higher rigidity and thermal stability compared to PA6 (nylon 6). Both materials are suitable for the specified operating temperature ranges and application environments.

Q: Are the substitute parts compatible with the same contact pins as the original WPJR-02V-2-R(NN)?

A: Yes. All substitute parts maintain the same 5.00mm pitch, 2-position configuration, and crimp termination method, ensuring compatibility with the same contact pin designs.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life and does not require special moisture-controlled storage conditions. This applies to all listed parts.

Q: Can I use a substitute part with a wider operating temperature range in place of the original?

A: Yes. The substitute parts with -40°C to 105°C operating ranges are backward compatible with applications designed for the original -25°C to 85°C range. The extended range provides additional thermal margin for demanding environments.
