Equivalent & Substitute Parts for B5J3R0

Part Overview

The B5J3R0 is a 3 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 features. The part is currently active in production with 888 units in stock. Alternative part numbers may be required due to packaging specifications, RoHS compliance requirements, or inventory availability in specific distribution channels.

Substitute Part Grouping Explanation

Substitution for the B5J3R0 is based on electrical and mechanical parameter equivalence within the Brown Devil® 200 series. The substitute part B5J3R0E maintains identical electrical specifications: 3 Ohm resistance, ±5% tolerance, 5.25W power rating, and ±400ppm/°C temperature coefficient. Both parts share the same wirewound composition, axial package configuration, and physical dimensions (0.250" Dia x 0.625" L). The primary distinction between these parts is packaging format and RoHS compliance status. Substitution is valid when the application requirements permit either bulk or tape packaging and when RoHS compliance levels are compatible with the end-use specification.

Parameter Comparison

Engineering Selection Recommendations

Both B5J3R0 and B5J3R0E are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts depends on two factors: packaging requirements and RoHS compliance mandates.

The B5J3R0 is suitable for applications where standard packaging is specified and RoHS non-compliance is acceptable. The B5J3R0E is the appropriate choice for designs requiring ROHS3 compliance or bulk packaging formats. Both parts deliver equivalent performance in circuit applications requiring 3 Ohm, 5.25W wirewound resistors with axial configuration and flame retardant safety features.

Frequently Asked Questions (FAQ)

Q: Are B5J3R0 and B5J3R0E electrically identical? A: Yes. Both parts have identical resistance (3 Ohms), tolerance (±5%), power rating (5.25W), temperature coefficient (±400ppm/°C), and composition (wirewound). They are electrically equivalent.

Q: What is the difference between these two part numbers? A: The primary differences are packaging format (standard versus bulk) and RoHS compliance status (non-compliant versus ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Can I substitute B5J3R0E for B5J3R0 in my design? A: Substitution is valid if your application permits bulk packaging and does not require RoHS non-compliance. If your design specifically mandates RoHS non-compliance or standard packaging, substitution is not appropriate.

Q: Do these parts have the same physical dimensions? A: Yes. Both parts measure 0.250" Dia x 0.625" L (6.35mm x 15.88mm) and use axial package configuration, making them mechanically interchangeable in through-hole layouts.

Q: What does ROHS3 compliance mean for B5J3R0E? A: ROHS3 compliance indicates the part meets Restriction of Hazardous Substances Directive requirements. This is relevant for applications subject to EU environmental regulations or customer specifications requiring RoHS compliance.

Q: Are both parts currently available? A: Yes. B5J3R0 has 888 units in stock and B5J3R0E has 1041 units in stock, both listed as active production parts.
