Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B5J330 is determined by strict equivalence across the following critical parameters:

• Resistance value: 330 Ohms
• 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
• Safety and flame retardant features

The B5J330E meets all these criteria and is classified as a parametric equivalent. Packaging differences (tape and reel versus bulk) do not affect electrical or mechanical compatibility for circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

Both the B5J330 and B5J330E are active production components from Ohmite's Brown Devil® 200 series with identical electrical and mechanical specifications. The B5J330E offers ROHS3 compliance, making it suitable for applications requiring RoHS certification. The B5J330 remains available for applications where RoHS compliance is not a requirement. Selection between these parts should be based on regulatory compliance needs and packaging format availability for your procurement process.

Frequently Asked Questions (FAQ)

Q: Can the B5J330E be used as a direct replacement for the B5J330?

A: Yes. The B5J330E is electrically and mechanically equivalent to the B5J330. Both components share identical resistance, tolerance, power rating, physical dimensions, and thermal characteristics. The primary difference is packaging format and RoHS compliance status.

Q: What is the difference between tape and reel packaging and bulk packaging?

A: Tape and reel packaging is used for automated assembly processes, while bulk packaging is used for manual assembly or smaller production runs. Both packaging formats contain the same component with identical electrical and mechanical properties.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical electrical characteristics and power dissipation.

Q: Are the physical dimensions identical between B5J330 and B5J330E?

A: Yes. Both components measure 0.250" diameter by 0.625" length (6.35mm x 15.88mm) and are fully compatible with existing PCB layouts and through-hole mounting.

Q: What does MSL 1 (Unlimited) mean on the B5J330E?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life under normal storage conditions and requires no special moisture control during handling or storage.
