B20J200 Equivalent & Substitute Parts

Part Overview

The B20J200 is a 200 Ohm, 20W wirewound axial 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 778 units in stock. Substitute parts are identified to address packaging variations, compliance requirements, and inventory availability while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

The B20J200E is classified as a parametric equivalent based on identical electrical characteristics and mechanical dimensions. Substitution is valid when the following criteria are met:

• Resistance value: 200 Ohms (exact match)
• Tolerance: ±5% (exact match)
• Power rating: 20W (exact match)
• Composition: Wirewound (exact match)
• Package: Axial (exact match)
• Temperature coefficient: ±260ppm/°C (exact match)
• Physical dimensions: 0.437" Dia x 2.000" L (exact match)
• Number of terminations: 2 (exact match)

The primary distinction between B20J200 and B20J200E is packaging format (tape/reel versus bulk) and RoHS compliance status, which do not affect electrical or mechanical interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both B20J200 and B20J200E are active production components suitable for direct substitution in 200 Ohm, 20W axial resistor applications. Selection between these parts should be based on:

• RoHS compliance requirements: B20J200E meets ROHS3 compliance; B20J200 does not
• Packaging requirements: B20J200E is supplied in bulk packaging; B20J200 packaging format is not specified
• Inventory availability: B20J200E has 922 units in stock versus 778 units for B20J200
• Supply chain constraints: Either part may be selected based on lead time and procurement logistics

Both components maintain identical electrical performance, mechanical fit, and thermal characteristics across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Can B20J200E replace B20J200 in existing designs?

A: Yes. Both parts are electrically and mechanically identical. The B20J200E can be substituted directly without circuit redesign or performance impact.

Q: What is the difference between B20J200 and B20J200E?

A: The primary differences are packaging format and RoHS compliance status. B20J200E is ROHS3 compliant and supplied in bulk packaging. Electrical specifications and physical dimensions are identical.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical or thermal performance. Both parts deliver identical 200 Ohm resistance, 20W power rating, and ±260ppm/°C temperature coefficient.

Q: Are the physical dimensions identical?

A: Yes. Both B20J200 and B20J200E measure 0.437" diameter by 2.000" length (11.11mm x 50.80mm) and are compatible with identical PCB layouts and mechanical assemblies.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements and supply chain preferences. For applications requiring RoHS compliance, specify B20J200E. Both parts are active production items with adequate inventory.
