• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.394" Dia x 1.858" L (exact match required)
• Temperature coefficient: ±30ppm/°C (exact match required)
• Features: Flame retardant coating and safety construction (exact match required)

The 20J12RE meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the 20J12R and 20J12RE are electrically and mechanically identical, with all critical parameters matching exactly. The primary distinction is regulatory compliance status: the 20J12RE is ROHS3 compliant, while the 20J12R is RoHS non-compliant. Selection between these parts should be based on application requirements regarding RoHS compliance. The 20J12RE offers higher inventory availability (1134 units versus 819 units) and is supplied in bulk packaging. Both parts maintain active production status and identical electrical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can 20J12RE be used as a direct replacement for 20J12R?

A: Yes. The 20J12RE is electrically and mechanically identical to the 20J12R. All resistance, tolerance, power rating, composition, package type, dimensions, and thermal characteristics are identical. The primary difference is RoHS compliance status.

Q: What is the difference between 20J12R and 20J12RE?
