Key Parameters

Substitute Part Grouping Explanation

The B8J10R and B8J10RE are parametric equivalents within the Brown Devil® 200 series. Substitution eligibility is determined by matching the following critical parameters:

• Resistance value: 10 Ohms
• Tolerance: ±5%
• Power rating: 8W
• Composition: Wirewound
• Package/Case: Axial
• Physical dimensions: 0.313" Dia x 1.000" L (7.94mm x 25.40mm)
• Temperature coefficient: ±260ppm/°C
• Features: Flame retardant coating and safety construction

Both parts maintain identical electrical performance and mechanical compatibility. The primary difference lies in packaging format (Box versus Bulk) and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both B8J10R and B8J10RE are functionally equivalent for circuit applications requiring 10 Ohms at 8W with axial through-hole mounting. Selection between these parts should be based on:

RoHS Compliance Requirements: The B8J10RE meets ROHS3 compliance, making it the appropriate choice for applications subject to RoHS directives. The B8J10R is RoHS non-compliant and should be selected only when RoHS compliance is not a requirement.

Packaging Needs: The B8J10R is supplied in Box packaging, while B8J10RE is supplied in Bulk packaging. Packaging selection depends on procurement volume and handling requirements.

Availability: Both parts are active and in stock. B8J10R has 1073 units available; B8J10RE has 926 units available.

Frequently Asked Questions (FAQ)

Q: Can B8J10RE be used as a direct replacement for B8J10R in all applications?

A: Yes, from an electrical and mechanical standpoint. Both parts have identical resistance (10 Ohms), tolerance (±5%), power rating (8W), composition (wirewound), package type (axial), dimensions (0.313" Dia x 1.000" L), and temperature coefficient (±260ppm/°C). The primary consideration is RoHS compliance status, which may be mandated by your application or regulatory environment.

Q: What is the difference between Box and Bulk packaging?

A: Box packaging (B8J10R) typically provides individual component packaging suitable for smaller quantities and controlled handling. Bulk packaging (B8J10RE) is designed for higher-volume procurement and automated assembly processes. Both contain the same component.

Q: Are there any dimensional differences between these parts?

A: No. Both B8J10R and B8J10RE have identical physical dimensions of 0.313" Dia x 1.000" L (7.94mm x 25.40mm) and are fully compatible in PCB layouts and through-hole mounting applications.

Q: Which part should I specify for new designs?

A: If RoHS compliance is required or anticipated, specify B8J10RE. If RoHS compliance is not applicable to your application, either part is acceptable based on packaging and availability requirements.

Q: Do these parts have the same temperature performance?

A: Yes. Both parts have an identical temperature coefficient of ±260ppm/°C, ensuring consistent performance across the operating temperature range.
