Substitute Part Grouping Explanation

Substitution for the B20J5R0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 5 Ohms
• Tolerance: ±5%
• Power rating: 20W
• Composition: Wirewound
• Package configuration: Axial through-hole
• Physical dimensions: 0.437" Dia x 2.000" L
• Temperature coefficient: ±400ppm/°C
• Features: Flame retardant coating and safety construction

The identified substitute, B20J5R0E, matches all electrical and mechanical parameters required for direct substitution. Both parts are manufactured by Ohmite and maintain identical functional specifications.

Parameter Comparison

Engineering Selection Recommendations

Both B20J5R0 and B20J5R0E are active production parts with equivalent electrical and mechanical specifications. The primary distinction is regulatory compliance: B20J5R0E is RoHS Compliant, while B20J5R0 is RoHS non-compliant. Selection between these parts should be based on application requirements and regulatory mandates. For applications requiring RoHS compliance, B20J5R0E is the appropriate choice. Both parts are classified under ECCN EAR99 and maintain identical HTSUS coding (8533.21.0080).

Frequently Asked Questions (FAQ)

Q: Can B20J5R0E be used as a direct replacement for B20J5R0?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance, tolerance, power rating, package type, and physical dimensions. They are interchangeable in circuit applications.

Q: What is the difference between B20J5R0 and B20J5R0E?

A: The primary differences are RoHS compliance status and moisture sensitivity level designation. B20J5R0E is RoHS Compliant with MSL 1 (Unlimited), while B20J5R0 is RoHS non-compliant with MSL Not Applicable. Electrical and mechanical performance are identical.

Q: Are there any package or footprint differences?

A: No. Both parts use identical axial through-hole packaging with dimensions of 0.437" Dia x 2.000" L (11.11mm x 50.80mm). PCB layout and mounting procedures are unchanged.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. For applications subject to RoHS directives, specify B20J5R0E. Both parts are active in production and available in stock.

Q: Are these parts suitable for high-temperature applications?

A: Both parts operate with a temperature coefficient of ±400ppm/°C. Specific operating temperature limits are not provided in the technical specifications. Consult detailed datasheets for thermal performance data.
