Difference: The B8J5R0E differs only in packaging format (Bulk) and compliance certifications, making it suitable for applications where RoHS3 compliance and REACH unaffected status are required.

Parameter Comparison

Engineering Selection Recommendations

B8J5R0: Select this part number for applications where RoHS non-compliant components are acceptable and standard packaging is required.

B8J5R0E: Select this part number for applications requiring RoHS3 compliance and REACH unaffected status. The bulk packaging format and higher inventory availability (1147 units) make this variant suitable for high-volume production environments.

Both parts are active products from the same manufacturer and series, with identical electrical and mechanical specifications. Selection between them depends solely on regulatory compliance requirements and packaging preferences.

Frequently Asked Questions (FAQ)

Q: Can B8J5R0E be used as a direct replacement for B8J5R0?

A: Yes. Both parts have identical resistance (5 Ohms), tolerance (±5%), power rating (8W), composition (Wirewound), package type (Axial), and physical dimensions (0.313" Dia x 1.000" L). The only differences are packaging format and compliance certifications.

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

A: B8J5R0 is supplied in standard packaging and is RoHS non-compliant. B8J5R0E is supplied in bulk packaging and is RoHS3 compliant with REACH unaffected status.

Q: Are the physical dimensions identical?

A: Yes. Both parts measure 0.313" Dia x 1.000" L (7.94mm x 25.40mm) and are axial through-hole components with two terminations.

Q: Which part should I select for a new design?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, use B8J5R0E. For applications without compliance requirements, either part is suitable based on packaging and inventory needs.

Q: Do these parts have the same temperature coefficient?

A: Yes. Both parts have a temperature coefficient of ±400ppm/°C.
