Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B5J20K is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 kOhms
• Tolerance: ±5%
• Power rating: 5.25W
• Composition: Wirewound
• Package configuration: Axial
• Physical dimensions: 0.250" Dia x 0.625" L (6.35mm x 15.88mm)
• Temperature coefficient: ±260ppm/°C
• Termination count: 2
• Series: Brown Devil® 200

The B5J20KE qualifies as a parametric equivalent based on identical electrical characteristics and mechanical specifications. The primary distinction is packaging format: B5J20K is supplied in box packaging, while B5J20KE is supplied in bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

Both B5J20K and B5J20KE are active production components with identical electrical and mechanical specifications. Selection between these parts should be based on the following factors:

B5J20K (Box Packaging): Select when individual unit packaging is required for controlled distribution, traceability, or small-quantity applications. This variant is RoHS non-compliant and currently has higher inventory availability at 1159 units.

B5J20KE (Bulk Packaging): Select when high-volume procurement is planned or when ROHS3 compliance is a system requirement. This variant offers regulatory compliance and maintains full electrical and mechanical equivalence despite the packaging difference.

Both parts share identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications, ensuring consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Are B5J20K and B5J20KE electrically identical?

A: Yes. Both components have identical resistance (20 kOhms), tolerance (±5%), power rating (5.25W), temperature coefficient (±260ppm/°C), and composition (wirewound). They are parametric equivalents.

Q: What is the difference between these parts?

A: The primary differences are packaging format (box versus bulk) and RoHS compliance status. B5J20K is supplied in box packaging and is RoHS non-compliant. B5J20KE is supplied in bulk packaging and is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Can B5J20KE be used as a direct replacement for B5J20K in PCB assembly?

A: Yes. The identical axial package configuration (0.250" Dia x 0.625" L), two-termination design, and physical dimensions ensure direct mechanical and electrical compatibility in any application designed for B5J20K.

Q: Does packaging format affect component performance?

A: No. Packaging format (box versus bulk) is a supply chain and logistics consideration only. It does not affect electrical performance, thermal characteristics, or reliability of the resistor itself.

Q: Which part should be selected for RoHS-compliant applications?

A: B5J20KE is ROHS3 compliant and should be selected for applications or systems with RoHS compliance requirements. B5J20K is RoHS non-compliant.

Q: Are there any differences in termination or lead configuration?

A: No. Both parts have identical two-termination axial configuration with the same physical dimensions and lead specifications.
