Ohmite 23J82RE 3W 82 Ohms Wirewound Resistor - Equivalent & Substitute Parts

Part Overview

The Ohmite 23J82RE is a 3W wirewound resistor with 82 ohms resistance and ±5% tolerance, designed for through-hole axial applications. This component features flame retardant coating and safety-rated construction, making it suitable for industrial and safety-critical applications. The part is currently active in production with RoHS compliance certification. Substitute parts may be required due to packaging availability, inventory constraints, or specific compliance requirements in your supply chain.

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 23J82RE is determined by strict parametric matching across the following critical criteria:

• Resistance value: 82 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Features: Flame retardant coating and safety construction (exact match required)
• Physical dimensions: 0.220" Dia x 0.516" L (exact match required)

The Ohmite 23J82R meets all parametric requirements for direct substitution. The primary difference is packaging format (bulk versus box), which does not affect electrical or mechanical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The Ohmite 23J82R is a direct parametric equivalent to the 23J82RE across all electrical and mechanical specifications. Both parts are manufactured by Ohmite in the Series 20 line and maintain active production status.

The primary distinction between these parts is RoHS compliance status. The 23J82RE carries RoHS Compliant certification, while the 23J82R is RoHS non-compliant. Selection between these parts must be based on your application's regulatory requirements:

• For applications requiring RoHS compliance or operating in regulated markets (EU, automotive, medical), the 23J82RE is the appropriate selection.
• For applications without RoHS compliance mandates, the 23J82R provides equivalent electrical and mechanical performance with higher inventory availability (1128 pcs versus 750 pcs).

Packaging format differs (box versus bulk), but this affects only procurement and handling procedures, not circuit performance or installation compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 23J82R be used as a direct replacement for the 23J82RE in my circuit?

A: Yes, from an electrical and mechanical standpoint. Both parts are identical in resistance, tolerance, power rating, composition, temperature coefficient, and physical dimensions. The substitution is valid for circuit functionality. However, regulatory compliance requirements must be evaluated separately based on your application's RoHS obligations.

Q: What is the difference between box and bulk packaging?

A: Packaging format refers only to how the components are supplied and stored. Box packaging typically includes individual packaging per unit or small quantities, while bulk packaging supplies larger quantities in standard containers. This distinction does not affect the electrical performance, mechanical fit, or reliability of the resistor in your application.

Q: Why does the 23J82R show RoHS non-compliant status?

A: RoHS compliance is a regulatory certification status determined by the manufacturer and supplier. The 23J82RE has been certified as RoHS compliant, while the 23J82R has not received this certification. If your application or market requires RoHS compliance, the 23J82RE must be specified. If RoHS compliance is not a requirement, both parts perform identically.

Q: Are there any performance differences between these two parts?

A: No. Both parts share identical electrical characteristics (82 Ohms ±5%, 3W, ±30ppm/°C), mechanical construction (wirewound, flame retardant, safety-rated), and physical dimensions (0.220" Dia x 0.516" L). Performance in circuit applications is equivalent.

Q: Which part should I specify for new designs?

A: Specify the 23J82RE for new designs unless RoHS compliance is explicitly not required by your application or market. The 23J82RE's RoHS compliance status provides broader compatibility with current regulatory environments and future supply chain requirements.
