Substitute Part Grouping Explanation

Substitution for the Ohmite 23J39R is based on strict equivalence of the following critical parameters:

• Resistance value: 39 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial
• Physical dimensions: 0.220" Dia x 0.516" L
• Temperature coefficient: ±30ppm/°C
• Number of terminations: 2

The identified substitute part maintains all electrical and mechanical specifications. Variations in packaging format (Bulk vs. standard packaging) and compliance certifications do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the 23J39R and 23J39RE are Active status components manufactured by Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on the following criteria:

23J39R is suitable for applications where standard packaging is required and RoHS non-compliant components are acceptable.

23J39RE is the appropriate choice for applications requiring RoHS compliance, as it meets RoHS Compliant certification. This part is packaged in Bulk format and carries MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.

Both parts are functionally equivalent in circuit performance and physical installation. The choice between them depends on regulatory requirements, packaging specifications, and supply chain constraints rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can 23J39RE be used as a direct replacement for 23J39R?

A: Yes. Both parts are electrically and mechanically identical with 39 Ohm resistance, ±5% tolerance, 3W power rating, and axial package configuration. The primary difference is RoHS compliance status and packaging format.

Q: What is the significance of the RoHS compliance difference?

A: RoHS compliance is a regulatory requirement in certain markets and applications. The 23J39RE meets RoHS Compliant standards, while the 23J39R is RoHS non-compliant. Selection depends on end-application regulatory requirements.

Q: Are the physical dimensions identical between both parts?

A: Yes. Both parts have identical dimensions of 0.220" Dia x 0.516" L (5.60mm x 13.10mm), ensuring identical PCB footprint and mounting compatibility.

Q: What does the packaging format difference mean?

A: The 23J39R uses standard packaging, while the 23J39RE is supplied in Bulk packaging. This affects order quantities and handling but does not impact component performance or functionality.

Q: Are there any thermal or environmental performance differences?

A: No. Both parts share identical temperature coefficient (±30ppm/°C), operating characteristics, and flame retardant coating with safety features.
