Substitute Part Grouping Explanation

Substitute parts for the 95J39R are identified based on strict electrical and mechanical parameter matching within the Ohmite 90 series. The substitution criteria are:

• Resistance value: 39 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 5W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial (exact match required)
• Dimensions: 0.264" Dia x 0.969" L (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Features: Flame retardant coating and safety features (exact match required)
• Number of terminations: 2 (exact match required)

The 95J39RE meets all these criteria and is therefore classified as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

Both the 95J39R and 95J39RE are Active status components from Ohmite's 90 series with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: the 95J39RE is ROHS3 compliant, while the 95J39R is RoHS non-compliant. Selection between these parts depends on application requirements and regulatory jurisdiction. For applications subject to RoHS3 regulations, the 95J39RE is the appropriate choice. For applications without RoHS3 requirements, either part is electrically and mechanically interchangeable. Both components carry identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Are the 95J39R and 95J39RE electrically identical?
