Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B5J2K2 is determined by strict equivalence across the following critical parameters:

• Resistance value: 2.2 kOhms
• Tolerance: ±5%
• Power rating: 5.25W
• Composition: Wirewound
• Package / Case: Axial
• Physical dimensions: 0.250" Dia x 0.625" L (6.35mm x 15.88mm)
• Temperature coefficient: ±260ppm/°C
• Features: Flame retardant coating and safety construction

The B5J2K2E qualifies as a parametric equivalent substitute. Both parts share identical electrical characteristics, mechanical dimensions, and functional features. The primary difference lies in packaging configuration and RoHS compliance status, which do not affect electrical performance or physical compatibility in circuit applications.

Engineering Selection Recommendations

Both B5J2K2 and B5J2K2E are active production parts suitable for direct substitution based on electrical and mechanical equivalence. Selection between these parts should be based on the following criteria:

B5J2K2 is appropriate for applications where RoHS non-compliant components are acceptable and standard packaging is preferred.

B5J2K2E is appropriate for applications requiring ROHS3 compliance or bulk packaging configurations. This variant provides enhanced environmental compliance without compromising electrical performance or mechanical compatibility.

Both parts carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications, ensuring consistent regulatory treatment in procurement and logistics.

Frequently Asked Questions (FAQ)

Q: Can B5J2K2E replace B5J2K2 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The B5J2K2E can be substituted directly without circuit redesign or board layout modifications. Physical dimensions, termination style, and electrical characteristics are equivalent.

Q: What is the difference between B5J2K2 and B5J2K2E?

A: The primary differences are packaging format (standard vs. bulk) and RoHS compliance status. B5J2K2E is ROHS3 compliant, while B5J2K2 is RoHS non-compliant. Electrical performance and physical form factor are identical.

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

A: No. Both parts share identical temperature coefficient (±260ppm/°C), power rating (5.25W), and thermal characteristics. Performance in thermal cycling and high-temperature applications is equivalent.

Q: Which part should I specify for new designs?

A: Specify based on compliance requirements. For applications requiring RoHS3 compliance, use B5J2K2E. For applications without RoHS requirements, either part is suitable. Verify packaging requirements with your procurement process.

Q: Are these parts interchangeable in PCB assembly?

A: Yes. Both parts use identical axial through-hole terminations and physical dimensions (0.250" Dia x 0.625" L). No changes to PCB footprints, assembly processes, or handling procedures are required.
