B5J4K7 Equivalent & Substitute Parts

Part Overview

The B5J4K7 is a 4.7 kOhms ±5% 5.25W through-hole wirewound resistor manufactured by Ohmite, part of the Brown Devil® 200 series. This axial flame retardant coated component is designed for applications requiring high power dissipation with safety-rated wirewound construction. The part maintains active product status with 661 units in current inventory. Substitute parts are identified to address packaging preferences, inventory availability, or supply chain requirements while maintaining identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of B5J4K7 with B5J4K7E is based on electrical and mechanical parameter equivalence. Both parts share identical core specifications: 4.7 kOhms resistance, ±5% tolerance, and 5.25W power rating. The wirewound composition, axial package configuration, and physical dimensions remain constant across both variants. The primary distinction is packaging format: B5J4K7 is supplied in box packaging, while B5J4K7E is supplied in bulk packaging. Both maintain the same RoHS non-compliant status and ECCN classification (EAR99). This substitution is valid for applications where packaging format does not impose constraints on assembly or inventory management procedures.

Parameter Comparison

Engineering Selection Recommendations

Both B5J4K7 and B5J4K7E are active products with identical electrical performance and mechanical compatibility. Selection between these variants should be based on packaging requirements and inventory availability. B5J4K7E offers higher current inventory (1179 units versus 661 units), which may provide supply chain advantages for high-volume applications. Both parts maintain equivalent RoHS non-compliance status and export classification. No performance differentiation exists between the two variants for circuit design purposes.

Frequently Asked Questions (FAQ)

Q: Can B5J4K7E be used as a direct replacement for B5J4K7 in circuit applications? A: Yes. Both parts are electrically and mechanically identical, with 4.7 kOhms resistance, ±5% tolerance, and 5.25W power rating. The only difference is packaging format (box versus bulk).

Q: What is the significance of the packaging difference between B5J4K7 and B5J4K7E? A: Packaging format affects inventory management and assembly procedures. Box packaging (B5J4K7) provides individual unit containment, while bulk packaging (B5J4K7E) supplies components in larger quantities without individual packaging. Electrical and mechanical performance is identical.

Q: Are there any compliance or certification differences between these parts? A: No. Both parts share identical RoHS status (non-compliant), ECCN classification (EAR99), and HTSUS codes (8533.21.0080). Compliance profiles are equivalent.

Q: Which part should be selected for new designs? A: Either part is suitable for new designs. Selection should consider packaging preferences, supply chain logistics, and inventory requirements. Both maintain active product status with equivalent technical specifications.

Q: Is the temperature coefficient specification identical for both parts? A: The temperature coefficient of ±260ppm/°C is specified for B5J4K7. B5J4K7E detailed specifications do not include this parameter in the provided data; however, as a direct equivalent, identical thermal performance is expected.
