Substitute Part Grouping Explanation

Substitution for the B20J30K is based on strict electrical and mechanical parameter matching. The following criteria determine valid substitutes:

• Resistance value: 30 kOhms
• Tolerance: ±5%
• Power rating: 20W
• Composition: Wirewound
• Package: Axial configuration
• Physical dimensions: 0.437" Dia x 2.000" L (11.11mm x 50.80mm)
• Temperature coefficient: ±260ppm/°C
• Features: Flame retardant coating and safety construction

The B20J30KE meets all these parameters and is identified as a parametric equivalent. Both parts are manufactured by Ohmite and share identical electrical specifications and physical form factors.

Parameter Comparison

Engineering Selection Recommendations

Both B20J30K and B20J30KE are active production parts with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: B20J30KE is RoHS compliant with MSL rating of 1 (Unlimited), while B20J30K is RoHS non-compliant. Selection between these parts should be based on application requirements for regulatory compliance and environmental standards. Both parts are available in adequate inventory quantities for production use.

Frequently Asked Questions (FAQ)

Q: Can B20J30KE be used as a direct replacement for B20J30K?

A: Yes. Both parts share identical electrical parameters (30 kOhms ±5%, 20W), composition (wirewound), package type (axial), physical dimensions (0.437" Dia x 2.000" L), and temperature coefficient (±260ppm/°C). They are mechanically and electrically interchangeable.

Q: What is the difference between B20J30K and B20J30KE?

A: The primary differences are RoHS compliance status and moisture sensitivity level. B20J30KE is RoHS compliant with MSL 1 (Unlimited), while B20J30K is RoHS non-compliant with no MSL rating. Electrical and mechanical specifications are identical.

Q: Are there any packaging differences between these parts?

A: B20J30K packaging is not specified in available data. B20J30KE is supplied in bulk packaging. Both parts maintain the same axial form factor and physical dimensions.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, B20J30KE is the appropriate choice. Both parts are active production items with stable inventory availability.

Q: Are the physical dimensions identical between substitute parts?

A: Yes. Both B20J30K and B20J30KE have identical dimensions of 0.437" Dia x 2.000" L (11.11mm x 50.80mm), ensuring compatibility in existing PCB layouts and mechanical assemblies.
