B8J75R Equivalent & Substitute Parts

Part Overview

The B8J75R is a 75 Ohm, 8W axial wirewound resistor manufactured by Ohmite as part of the Brown Devil® 200 series. This through-hole component features flame retardant coating and safety construction, designed for applications requiring high power dissipation in a compact axial package. The part is currently active in production with 1035 units in stock. Substitute parts are identified to address packaging variations, compliance requirements, and inventory availability while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B8J75R is determined by strict equivalence across the following critical parameters:

• Resistance value: 75 Ohms
• Tolerance: ±5%
• Power rating: 8W
• Composition: Wirewound
• Package configuration: Axial
• Physical dimensions: 0.313" Dia x 1.000" L
• Temperature coefficient: ±260ppm/°C
• Number of terminations: 2
• Features: Flame Retardant Coating, Safety

The B8J75RE qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. Variations in packaging format (Bulk vs. standard) and RoHS compliance status do not affect functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

Both B8J75R and B8J75RE are active production components from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and packaging needs:

The B8J75R is suitable for applications where RoHS non-compliance is acceptable or where legacy component specifications are required.

The B8J75RE is the appropriate selection for applications requiring ROHS3 compliance and is available in bulk packaging format. This variant maintains full functional equivalence while meeting modern regulatory standards.

Both parts are suitable for direct substitution in circuit designs requiring 75 Ohm, 8W axial wirewound resistors with flame retardant coating and safety construction.

Frequently Asked Questions (FAQ)

Q: Can B8J75RE be used as a direct replacement for B8J75R in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The B8J75RE differs only in RoHS compliance status and packaging format, which do not affect circuit performance or physical fit.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The B8J75R is RoHS non-compliant, while B8J75RE is ROHS3 compliant. Selection depends on end-product regulatory requirements. Applications subject to RoHS directives must use the B8J75RE variant.

Q: Are the physical dimensions identical between B8J75R and B8J75RE?

A: Yes. Both parts measure 0.313" diameter by 1.000" length (7.94mm x 25.40mm) and are packaged in axial configuration. They are mechanically interchangeable on PCBs.

Q: What does the packaging designation "Bulk" mean for the B8J75RE?

A: Bulk packaging indicates the component is supplied in loose form rather than in tape-and-reel or other formatted packaging. This does not affect the component's electrical or mechanical properties.

Q: Are there any thermal or environmental performance differences between these substitutes?

A: No. Both parts share identical temperature coefficient (±260ppm/°C), power rating (8W), and feature set (Flame Retardant Coating, Safety). Environmental performance is equivalent.
