Engineering Selection Recommendations
All three parts—WPJR-03V-2-R, 2-1241961-8, and 969484-8—are active production components with full RoHS compliance. The WPJR-03V-2-R maintains an operating temperature range of -25°C to 85°C. The TE Connectivity alternatives (2-1241961-8 and 969484-8) extend the upper operating temperature to 105°C and lower temperature to -40°C, providing broader thermal performance margins.
Selection between these parts should be based on:
- Supply availability: TE Connectivity parts show higher inventory levels (1307 and 1868 units respectively versus 710 units for WPJR-03V-2-R)
- Thermal requirements: Applications requiring operation below -25°C or above 85°C necessitate the TE Connectivity alternatives
- Compliance requirements: All parts meet RoHS standards; TE parts carry ROHS3 designation
- Packaging format: All parts are supplied in bulk packaging
Frequently Asked Questions (FAQ)
Q: Can 2-1241961-8 or 969484-8 be used as direct replacements for WPJR-03V-2-R?
A: Yes. Both TE Connectivity parts meet all critical electrical and mechanical parameters: 3-position receptacle, 5.00mm pitch, female socket contacts, crimp termination, and latch lock fastening. Physical and electrical compatibility is maintained.
Q: What are the differences between 2-1241961-8 and 969484-8?
A: Both parts are functionally equivalent with identical connector specifications. The primary difference is inventory availability (1307 units for 2-1241961-8 versus 1868 units for 969484-8). Operating temperature data is not specified for 969484-8, while 2-1241961-8 is rated -40°C to 105°C.
Q: Are there temperature limitations when substituting parts?
A: The WPJR-03V-2-R operates from -25°C to 85°C. If your application requires operation outside this range, the TE Connectivity alternatives (2-1241961-8 rated -40°C to 105°C) provide extended thermal capability.
Q: Do all parts include contacts?
A: No. All three parts are connector housings only. Contacts are not included and must be sourced separately.
Q: Are MSL ratings identical across all parts?
A: Yes. All three parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
Q: What is the difference in RoHS compliance between the parts?
A: WPJR-03V-2-R is RoHS Compliant. Both TE Connectivity parts carry ROHS3 Compliant designation, which represents the current RoHS standard revision.
