B20J100K Equivalent & Substitute Parts

Part Overview

The B20J100K is a 100 kOhms ±5% 20W 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 compact form factors. The part is currently active in production with 915 units in stock. Substitute parts are identified when inventory constraints, compliance requirements, or specific packaging needs necessitate alternative sourcing while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the B20J100K is determined by strict equivalence across the following critical parameters:

• Resistance Value: 100 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Power Rating: 20W (exact match required)
• Composition: Wirewound (exact match required)
• Package Type: Axial (exact match required)
• Physical Dimensions: 0.437" Dia x 2.000" L (exact match required)
• Temperature Coefficient: ±260ppm/°C (exact match required)
• Features: Flame Retardant Coating, Safety (exact match required)

The B20J100KE qualifies as a parametric equivalent substitute, meeting all electrical and mechanical specifications. Differences in RoHS compliance status and inventory availability do not affect functional interchangeability in applications where the core electrical and physical parameters are the determining factors.

Parameter Comparison

Engineering Selection Recommendations

Both B20J100K and B20J100KE are active production components from Ohmite's Brown Devil® 200 series with identical electrical and mechanical specifications. Selection between these parts should be based on compliance requirements and inventory availability:

The B20J100K is suitable for applications where RoHS non-compliance is acceptable or where legacy component specifications are required. The B20J100KE provides ROHS3 compliance and REACH unaffected status, making it the appropriate choice for applications subject to environmental regulations or customer compliance mandates. Both parts are functionally interchangeable in circuit design and PCB layout.

Frequently Asked Questions (FAQ)

Q: Can B20J100KE be used as a direct replacement for B20J100K?

A: Yes. Both parts share identical resistance value (100 kOhms), tolerance (±5%), power rating (20W), composition (wirewound), package type (axial), physical dimensions (0.437" Dia x 2.000" L), temperature coefficient (±260ppm/°C), and safety features. They are parametric equivalents.

Q: What is the difference between B20J100K and B20J100KE?

A: The primary differences are RoHS compliance status and inventory levels. B20J100K is RoHS non-compliant with 915 units in stock. B20J100KE is ROHS3 compliant with REACH unaffected status and 1039 units in stock. All electrical and mechanical parameters are identical.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.437" diameter by 2.000" length (11.11mm x 50.80mm), ensuring identical PCB footprint and mounting compatibility.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring environmental compliance, B20J100KE is the appropriate choice due to ROHS3 compliance. For applications without compliance constraints, either part is suitable based on availability.

Q: Do these parts have the same temperature coefficient?

A: Yes. Both B20J100K and B20J100KE have a temperature coefficient of ±260ppm/°C, ensuring equivalent thermal performance across operating ranges.
