Substitute Part Grouping Explanation

Substitution of the L225J3R0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 3 Ohms
• Tolerance: ±5%
• Power rating: 225W
• Composition: Wirewound
• Temperature coefficient: ±400ppm/°C
• Operating temperature range: -55°C to 350°C
• Housing type: Vitreous enamel coated
• Package type: Radial, tubular
• Lead style: Solder lugs
• Physical dimensions: Compatible within manufacturing tolerances

The FVT20020E3R000JE from Vishay Huntington Electric Inc. meets all electrical and mechanical parameters required for direct substitution. Dimensional compatibility is confirmed with a diameter of 1.125" (28.58mm) and length of 10.500" (266.70mm), representing negligible variation within standard manufacturing tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both the L225J3R0 and FVT20020E3R000JE are active products with confirmed inventory availability. The L225J3R0 remains suitable for applications without RoHS compliance requirements. The FVT20020E3R000JE provides an equivalent alternative with ROHS3 compliance certification, making it the appropriate selection for applications subject to RoHS3 regulatory requirements or customer specifications mandating RoHS compliance. Both components share identical electrical performance characteristics and are mechanically compatible within standard manufacturing tolerances.

Frequently Asked Questions (FAQ)

Q: Can the FVT20020E3R000JE directly replace the L225J3R0 in existing designs?

A: Yes. Both components meet identical specifications for resistance value, tolerance, power rating, temperature coefficient, and operating temperature range. Physical dimensions are compatible within standard manufacturing tolerances. No circuit modifications are required.

Q: What is the primary difference between these two parts?

A: The FVT20020E3R000JE carries ROHS3 compliance certification, while the L225J3R0 is RoHS non-compliant. All electrical and mechanical parameters are equivalent.

Q: Are there any dimensional concerns with substitution?

A: No. The diameter difference of 0.001" (0.02mm) and identical length specifications fall within standard manufacturing tolerances for chassis mount resistors. Both components use identical solder lug termination and mounting bracket interfaces.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and customer requirements. For applications requiring RoHS3 compliance, specify the FVT20020E3R000JE. For applications without compliance mandates, either part is acceptable based on availability and sourcing preferences.

Q: Are both parts currently in stock?

A: Yes. The L225J3R0 has 987 units in stock, and the FVT20020E3R000JE has 1130 units in stock as new original inventory.
