FMP4WVJR-73-30K Equivalent & Substitute Parts

Part Overview

The FMP4WVJR-73-30K is a 30 kOhms ±5% 4W through-hole resistor manufactured by YAGEO in axial configuration with flame-proof and safety features. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The metal film composition and axial package provide stable performance across industrial temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FMP4WVJR-73-30K is determined by the following critical parameters:

• Resistance Value: Must be 30 kOhms
• Tolerance: Must be ±5%
• Composition: Must be metal film
• Package: Must be axial through-hole
• Operating Temperature: Must support -55°C ~ 155°C range
• Safety Compliance: Must include flame-retardant or flame-proof features

The PR03000203002JAC00 meets all substitution criteria with one exception: power rating is 3W versus the original 4W specification. This represents a functional downgrade in power handling capacity and must be evaluated against circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The PR03000203002JAC00 is an active-status substitute that maintains electrical equivalence in resistance, tolerance, composition, and temperature range. The part is ROHS3 compliant and carries active manufacturer support, addressing the obsolescence status of the original FMP4WVJR-73-30K.

The primary consideration is power rating: the substitute is rated at 3W versus the original 4W. Selection of this substitute is appropriate only when circuit power dissipation does not exceed 3W at the 30 kOhm resistance value. Physical dimensions are smaller in the substitute (5.20mm diameter versus 7.50mm), which may affect PCB layout and thermal management in high-power applications.

Both parts maintain identical operating temperature ranges and equivalent safety certifications (flame-proof versus flame-retardant coating), ensuring thermal and safety performance parity within specified limits.

Frequently Asked Questions (FAQ)

Q: Can the PR03000203002JAC00 directly replace the FMP4WVJR-73-30K in all applications?

A: Direct replacement is valid only when circuit power dissipation does not exceed 3W. If the original design requires 4W power handling, the substitute will operate outside its rated specification.

Q: What is the difference between flame-proof and flame-retardant coating?

A: Both designations indicate safety features that prevent or inhibit flame propagation. Flame-proof provides absolute flame prevention, while flame-retardant coating reduces flame spread. Both meet safety requirements for this resistor category.

Q: Are there physical installation differences between these parts?

A: Yes. The substitute is physically smaller (5.20mm diameter versus 7.50mm). Verify PCB hole spacing and thermal clearances before installation. Axial lead length is comparable (16.70mm versus 17.00mm).

Q: Does the substitute provide better compliance or support?

A: The PR03000203002JAC00 is active-status with ROHS3 compliance, whereas the FMP4WVJR-73-30K is obsolete. The substitute offers ongoing manufacturer support and regulatory compliance advantages.

Q: What does the temperature coefficient specification mean?

A: The PR03000203002JAC00 specifies ±250ppm/°C, indicating resistance value changes by up to 250 parts per million for each degree Celsius change. This specification is not provided for the original part but is typical for metal film resistors in this category.
