• Composition: Wirewound (identical)
• Package type: Axial (identical)
• Physical dimensions: 0.313" Dia x 1.750" L (identical)
• Temperature coefficient: ±260ppm/°C (identical)
• Features: Flame Retardant Coating, Safety (identical)
• Terminations: 2 (identical)

The B12J150E maintains all critical electrical and mechanical parameters required for direct substitution in applications designed for the B12J150.

Parameter Comparison

Engineering Selection Recommendations

Both the B12J150 and B12J150E are active production parts from Ohmite with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements:

The B12J150E is RoHS Compliant with Moisture Sensitivity Level 1 (Unlimited), making it suitable for applications subject to RoHS directives and environments with no moisture sensitivity constraints.

The B12J150 is RoHS non-compliant and should be selected only for applications where RoHS compliance is not required or where legacy system compatibility is necessary.

Both parts carry ECCN classification EAR99 and are suitable for the same circuit applications given their identical electrical performance and physical form factor.
