Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FMP4WVJR-73-15R is determined by the following critical parameters:

• Resistance value: 15 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 (substitute must meet or exceed this range)
• Safety and flame characteristics: Flame-rated construction required

The PR03000201509JAC00 qualifies as a manufacturer-recommended substitute despite a lower power rating (3W versus 4W) because it maintains all critical electrical and mechanical parameters. 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 PR03000201509JAC00 is the manufacturer-recommended substitute for the obsolete FMP4WVJR-73-15R. Selection of this substitute is supported by:

• Active product status ensuring long-term availability and supply chain stability
• ROHS3 compliance meeting current regulatory requirements
• Identical resistance, tolerance, composition, and package specifications
• Matching operating temperature range and safety certifications
• Maintained REACH compliance status

The 3W power rating of the substitute is lower than the original 4W specification. Circuit-level thermal analysis is required to confirm that the substitute's power dissipation capability is adequate for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the PR03000201509JAC00 directly replace the FMP4WVJR-73-15R in all applications?

A: Direct replacement is possible only when circuit power dissipation does not exceed 3W at the 15 Ohm resistance value. Applications requiring the full 4W rating require alternative solutions or circuit redesign.

Q: What is the physical size difference between these parts?

A: The FMP4WVJR-73-15R measures 0.295" diameter × 0.669" length (7.50mm × 17.00mm). The PR03000201509JAC00 measures 0.205" diameter × 0.657" length (5.20mm × 16.70mm). Both are axial package types with identical lead spacing suitable for standard through-hole PCB layouts.

Q: Are there compliance differences between the main part and substitute?

A: The substitute (PR03000201509JAC00) carries ROHS3 compliance certification, whereas the main part specification does not include this designation. Both parts maintain REACH Unaffected status and EAR99 export classification.

Q: What is the temperature coefficient of the substitute?

A: The PR03000201509JAC00 has a temperature coefficient of ±250ppm/°C. The main part temperature coefficient is not specified in the available data.

Q: How does packaging affect substitution?

A: Both parts use axial through-hole packaging with identical electrical termination (2 leads). The substitute is available in Cut Tape (CT) packaging format. Packaging format does not affect electrical or mechanical compatibility.
