FMP4WVJR-73-10R Equivalent & Substitute Parts

Part Overview

The FMP4WVJR-73-10R is a 10 Ohm, 4W axial through-hole resistor manufactured by YAGEO with ±5% tolerance. This metal film resistor features flame-proof and safety characteristics, designed for through-hole applications requiring robust thermal performance. The part is currently obsolete, necessitating identification of functionally equivalent alternatives that maintain electrical and mechanical compatibility for existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FMP4WVJR-73-10R is determined by the following critical parameters:

• Resistance value: 10 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Composition: Metal Film (exact match required)
• Package: Axial through-hole (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• Safety and flame characteristics: Flame retardant or flame-proof coating required
• Number of terminations: 2 (exact match required)

The PR03000201009JAC00 qualifies as a substitute despite a lower power rating (3W versus 4W) because it maintains all critical electrical parameters, mechanical compatibility, and safety certifications. The reduced power rating represents a design trade-off acceptable in applications where the 3W rating is sufficient for the circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The PR03000201009JAC00 is an active, in-stock substitute for the obsolete FMP4WVJR-73-10R. Both components share identical resistance, tolerance, composition, operating temperature range, and safety certifications. The substitute maintains REACH compliance and export classification equivalence.

The primary design consideration is the power rating differential: the substitute is rated at 3W versus the original 4W specification. Selection of this substitute is appropriate when circuit analysis confirms that the maximum continuous power dissipation does not exceed 3W under worst-case operating conditions. The substitute's smaller physical dimensions (5.20mm diameter versus 7.50mm) may require PCB layout verification for mechanical clearance in existing designs.

The substitute's RoHS3 compliance provides additional regulatory advantage for new production runs and long-term supply chain sustainability.

Frequently Asked Questions (FAQ)

Q: Can the PR03000201009JAC00 directly replace the FMP4WVJR-73-10R in all applications?

A: Direct replacement is possible when the circuit's maximum power dissipation does not exceed 3W. The 10 Ohm resistance and ±5% tolerance are identical. Verify that the smaller physical dimensions (5.20mm diameter) do not create mechanical interference on the PCB.

Q: What is the significance of the power rating difference?

A: The substitute is rated for 3W continuous operation versus the original 4W. This represents a 25% reduction in thermal capacity. Applications operating at or near the original 4W specification require thermal analysis to confirm the substitute's adequacy.

Q: Are the safety and flame characteristics equivalent?

A: Both components provide safety-rated construction. The original features flame-proof characteristics; the substitute features flame-retardant coating with fusible properties. Both meet safety standards for their respective power ratings and operating temperatures.

Q: What are the physical dimension implications?

A: The substitute is smaller in diameter (5.20mm versus 7.50mm) but similar in length (16.70mm versus 17.00mm). Verify PCB hole spacing and component clearance before implementation.

Q: Is the substitute RoHS compliant?

A: Yes, the PR03000201009JAC00 is RoHS3 compliant, whereas the original part's RoHS status is not specified. This provides regulatory advantage for new designs and manufacturing.

Q: What is the availability status of each part?

A: The FMP4WVJR-73-10R is obsolete with limited remaining inventory. The PR03000201009JAC00 is active production with 5200 units in stock, ensuring long-term supply chain reliability.
