Key Parameters

Substitute Part Grouping Explanation

Substitution of the FMP4WVJR-73-22K is determined by the following critical parameters:

• Resistance Value: Must be 22 kOhms
• Tolerance: Must be ±5% or tighter
• Power Rating: Must be equal to or greater than 4W
• Composition: Metal film construction required
• Package Type: Axial configuration required
• Safety Features: Flame-proof and safety certifications required
• Termination Count: Two-terminal configuration required

The SQPR522KJ meets all substitution criteria with equivalent electrical characteristics and enhanced specifications in power rating (5W) and operating temperature range (-55°C ~ 250°C).

Parameter Comparison

Engineering Selection Recommendations

The SQPR522KJ is a direct functional substitute for the FMP4WVJR-73-22K. Both components share identical resistance, tolerance, and safety certifications. The substitute offers superior specifications including higher power rating (5W versus 4W) and extended operating temperature range (-55°C ~ 250°C versus -55°C ~ 155°C). Both parts maintain REACH Unaffected status and EAR99 export classification. The SQPR522KJ is currently in active production status, ensuring long-term availability and supply chain continuity compared to the obsolete FMP4WVJR-73-22K.

Frequently Asked Questions (FAQ)

Q: Can the SQPR522KJ directly replace the FMP4WVJR-73-22K in existing designs?

A: Yes. Both components are 22 kOhms ±5% metal film axial resistors with identical electrical characteristics and safety certifications. The substitute meets or exceeds all critical parameters.

Q: What are the physical dimension differences between these parts?

A: The FMP4WVJR-73-22K measures 0.295" Dia x 0.669" L (7.50mm x 17.00mm). The SQPR522KJ measures 0.394" x 0.354" Rectangular x 0.866" L (10.00mm x 9.00mm x 22.00mm). Both are axial configuration but with different physical profiles. PCB layout and mounting clearance must be verified.

Q: Are there compliance or certification differences?

A: Both parts are REACH Unaffected and EAR99 classified. The SQPR522KJ includes RoHS3 compliance certification. Both maintain flame-proof and safety features required for the application.

Q: Why is the SQPR522KJ rated for higher power and temperature?

A: The SQPR522KJ is a current-generation component with enhanced specifications. The higher 5W power rating and extended temperature range (-55°C ~ 250°C) provide additional design margin and operational flexibility compared to the obsolete 4W, -55°C ~ 155°C FMP4WVJR-73-22K.

Q: Is the SQPR522KJ available in the same packaging format?

A: Both components use axial through-hole packaging. However, physical dimensions differ. Verify PCB footprint compatibility and mounting space before implementation.
