Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 20J5R0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 5 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Package: Axial
• Temperature coefficient: ±50ppm/°C
• Physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Termination count: 2
• Features: Flame retardant coating and safety characteristics

The substitute part 20J5R0E meets all electrical and mechanical specifications identical to the main part. The primary distinction lies in compliance certification status, which may be relevant for specific regulatory or procurement requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 20J5R0 and 20J5R0E are electrically and mechanically equivalent components from Ohmite's Series 20 wirewound resistor line. Selection between these parts should be based on regulatory compliance requirements:

The 20J5R0 is suitable for applications where RoHS compliance is not mandated. The 20J5R0E provides ROHS3 compliance certification, making it the appropriate choice for designs subject to RoHS3 regulatory frameworks or procurement specifications requiring this certification. Both parts carry identical electrical performance characteristics, physical dimensions, and safety features. Inventory availability differs, with the 20J5R0E currently stocked at higher quantities (2573 units versus 1130 units).

Frequently Asked Questions (FAQ)

Q: Are the 20J5R0 and 20J5R0E electrically interchangeable?

A: Yes. Both parts are identical in resistance value (5 Ohms), tolerance (±5%), power rating (10W), temperature coefficient (±50ppm/°C), and all other electrical specifications. They are direct functional equivalents.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 20J5R0E is ROHS3 compliant, while the 20J5R0 is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Can I use the 20J5R0E as a replacement for the 20J5R0 in existing designs?

A: Yes. The 20J5R0E is a direct substitute with identical electrical performance and physical dimensions. No circuit modifications or PCB layout changes are required.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.394" diameter by 1.858" length (10.00mm x 47.20mm) in axial configuration with 2 terminations.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. For designs requiring RoHS3 compliance, specify the 20J5R0E. For applications without RoHS compliance mandates, either part is acceptable based on availability and procurement preferences.

Q: Do these parts have the same temperature coefficient?

A: Yes. Both the 20J5R0 and 20J5R0E have a temperature coefficient of ±50ppm/°C.
