Ohmite 20J330 10W 330 Ohms Wirewound Resistor Equivalent & Substitute Parts

Part Overview

The Ohmite 20J330 is a 10W wirewound resistor with 330 ohms resistance and ±5% tolerance, featuring flame retardant coating and safety construction in axial through-hole package. This component is currently active in production. Substitute parts are identified based on matching electrical specifications (resistance value, tolerance, power rating, temperature coefficient) and mechanical compatibility (package type, dimensions, termination count) while accounting for packaging format and compliance differences.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the Ohmite 20J330 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 330 Ohms
• Tolerance: ±5%
• Power rating: 10W
• Composition: Wirewound
• Temperature coefficient: ±30ppm/°C
• Package type: Axial through-hole
• Physical dimensions: 0.394" Dia x 1.858" L (10.00mm x 47.20mm)
• Termination count: 2
• Features: Flame retardant coating and safety construction

The primary difference between the main part and its substitute is packaging format (Box versus Bulk) and RoHS compliance status. All electrical and mechanical specifications remain identical.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite 20J330E serves as a direct electrical and mechanical equivalent to the 20J330. Selection between these parts should be based on:

• Packaging requirements: Choose 20J330 for box packaging or 20J330E for bulk packaging
• Regulatory compliance: The 20J330E is RoHS compliant, while the 20J330 is RoHS non-compliant. Applications requiring RoHS compliance must use the 20J330E
• Both parts are active products with identical electrical performance and physical dimensions

Frequently Asked Questions (FAQ)

Q: Can the 20J330E replace the 20J330 in all applications?

A: Yes, electrically and mechanically. The 20J330E is identical in resistance, tolerance, power rating, temperature coefficient, package type, and dimensions. The primary differences are packaging format and RoHS compliance status.

Q: What is the difference between Box and Bulk packaging?

A: Box packaging (20J330) typically includes individual component packaging suitable for smaller orders or specific handling requirements. Bulk packaging (20J330E) is supplied in larger quantities without individual boxes, reducing cost per unit for high-volume applications.

Q: Does RoHS compliance affect electrical performance?

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

Q: Are the physical dimensions identical?

A: Yes. Both the 20J330 and 20J330E measure 0.394" diameter by 1.858" length (10.00mm x 47.20mm) and are compatible with identical PCB layouts and mounting configurations.

Q: What applications require the RoHS-compliant version?

A: Applications subject to RoHS regulations, including consumer electronics, industrial equipment sold in RoHS-regulated markets, and systems requiring RoHS certification documentation must use the 20J330E.
