Key Parameters

Substitute Part Grouping Explanation

The B8J2R0E is classified as a parametric equivalent to the B8J2R0. Substitution is valid based on the following criteria:

• Identical resistance value: 2 Ohms
• Identical tolerance: ±5%
• Identical power rating: 8W
• Identical composition: Wirewound
• Identical package type: Axial
• Identical physical dimensions: 0.313" Dia x 1.000" L (7.94mm x 25.40mm)
• Identical temperature coefficient: ±400ppm/°C
• Identical features: Flame Retardant Coating, Safety
• Identical number of terminations: 2

The primary difference between these parts is packaging format (Bulk for B8J2R0E versus standard for B8J2R0) and RoHS compliance status. Both parts are manufactured by Ohmite within the Brown Devil® 200 series and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

Both B8J2R0 and B8J2R0E are electrically and mechanically identical, with all critical parameters matching across resistance, tolerance, power rating, composition, package type, and physical dimensions. Selection between these parts should be based on compliance requirements and packaging needs:

• Select B8J2R0E for applications requiring ROHS3 compliance
• Select B8J2R0 where RoHS compliance is not a requirement
• B8J2R0E is supplied in Bulk packaging, while B8J2R0 uses standard packaging
• Both parts maintain active production status and adequate inventory levels

Frequently Asked Questions (FAQ)

Q: Can B8J2R0E be used as a direct replacement for B8J2R0?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (2 Ohms), tolerance (±5%), power rating (8W), composition (Wirewound), package type (Axial), and physical dimensions (0.313" Dia x 1.000" L). The primary difference is RoHS compliance status and packaging format.

Q: What is the difference between B8J2R0 and B8J2R0E?

A: The B8J2R0E is ROHS3 compliant, while the B8J2R0 is RoHS non-compliant. B8J2R0E is supplied in Bulk packaging. All electrical and mechanical specifications are identical.

Q: Are there any dimensional differences between these parts?

A: No. Both parts share identical physical dimensions of 0.313" Dia x 1.000" L (7.94mm x 25.40mm) and are both axial package types, ensuring compatibility in PCB layouts and mechanical assemblies.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance, specify B8J2R0E. For applications without RoHS requirements, either part is suitable based on availability and packaging needs.

Q: Are both parts currently available?

A: Yes. B8J2R0 has 822 units in stock, and B8J2R0E has 1058 units in stock, both listed as new original inventory.
