Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 23JR25 is determined by matching the following critical parameters:

• Resistance value: 250 mOhms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package: Axial
• Physical dimensions: 0.220" Dia x 0.516" L (5.60mm x 13.10mm)
• Termination count: 2
• Features: Flame Retardant Coating, Safety

The substitute part 23JR25E meets all these criteria and is manufactured by Ohmite within the same Series 20 product line.

Parameter Comparison

Engineering Selection Recommendations

Both the 23JR25 and 23JR25E are active Ohmite Series 20 products with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: the 23JR25E achieves ROHS3 compliance, while the 23JR25 is RoHS non-compliant. Both parts share identical REACH and ECCN classifications. Selection between these parts depends on application regulatory requirements. The 23JR25E provides greater compliance flexibility for applications subject to RoHS3 mandates. Both parts maintain equivalent performance characteristics for resistance, power dissipation, and physical form factor.

Frequently Asked Questions (FAQ)

Q: Can the 23JR25E directly replace the 23JR25 in existing designs?

A: Yes. The 23JR25E is electrically and mechanically identical to the 23JR25. Both components share the same resistance value (250 mOhms), tolerance (±5%), power rating (3W), wirewound composition, axial package, and physical dimensions (0.220" Dia x 0.516" L). Direct substitution is valid from a functional standpoint.

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

A: The 23JR25E is ROHS3 compliant, while the 23JR25 is RoHS non-compliant. All other electrical, mechanical, and regulatory parameters are identical.

Q: Are there any inventory considerations for selecting between these parts?

A: The 23JR25E has higher current inventory (1022 units) compared to the 23JR25 (784 units). Availability may influence selection for high-volume applications.

Q: Do these parts have different thermal or environmental performance?

A: No. Both parts are identical in composition, features (flame retardant coating, safety), and package type. No thermal or environmental performance differences exist between them.

Q: Are both parts suitable for the same circuit board layouts?

A: Yes. Both components use the identical axial package with 2 terminations and matching physical dimensions. PCB footprints and through-hole spacing are compatible.
