Equivalent & Substitute Parts for B5J10R

Part Overview

The B5J10R is a 10 Ohm, 5.25W wirewound axial resistor manufactured by Ohmite as part of the Brown Devil® 200 series. This component is designed for through-hole applications requiring flame-retardant coating and safety-rated construction. The part is currently active in production with 672 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory constraints, supply chain considerations, or specific compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B5J10R is determined by matching the following critical parameters:

• Resistance value: 10 Ohms
• Tolerance: ±5%
• Power rating: 5.25W
• Composition: Wirewound
• Package: Axial
• Temperature coefficient: ±260ppm/°C
• Features: Flame retardant coating and safety construction
• Physical dimensions: 0.250" Dia x 0.625" L
• Number of terminations: 2

The B5J10RE meets all these criteria and is classified as a parametric equivalent. Differences in RoHS compliance status and moisture sensitivity level do not affect electrical or mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both B5J10R and B5J10RE are active production components from Ohmite's Brown Devil® 200 series with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements:

• B5J10R is suitable for applications where RoHS non-compliance is acceptable or not required.
• B5J10RE is required for applications mandating ROHS3 compliance.

Both parts are functionally interchangeable in circuit design and PCB layout. The B5J10RE offers higher inventory availability (1146 units versus 672 units), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Can B5J10RE be used as a direct replacement for B5J10R?

A: Yes. The B5J10RE is a parametric equivalent with identical resistance, tolerance, power rating, composition, package type, temperature coefficient, and physical dimensions. Direct substitution is electrically and mechanically valid.

Q: What is the difference between B5J10R and B5J10RE?

A: The primary differences are RoHS compliance status (B5J10R is non-compliant; B5J10RE is ROHS3 compliant) and moisture sensitivity level classification. Electrical and mechanical performance are identical.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts share identical axial package dimensions (0.250" Dia x 0.625" L) and two-terminal configuration. PCB footprints and mounting requirements are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory and compliance requirements. For applications requiring ROHS3 compliance, specify B5J10RE. For applications without RoHS requirements, either part is acceptable based on availability and cost considerations.

Q: Are both parts available in the same packaging format?

A: Yes. Both B5J10R and B5J10RE are supplied in bulk packaging as axial through-hole components.
