• Tolerance: ±5% (exact match required)
• Power Rating: 3.25W (exact match required)
• Composition: Wirewound (exact match required)
• Package Type: Axial (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Features: Flame Retardant Coating, Safety (exact match required)

The substitute part 93J2R4 meets all electrical and mechanical parameters required for direct substitution. Differences in RoHS compliance status and packaging documentation do not affect functional equivalence in applications where the primary electrical and thermal characteristics are the determining factors.

Parameter Comparison

Engineering Selection Recommendations

The 93J2R4E is the primary selection for applications requiring RoHS Compliance certification. Both parts are Active status products from the same manufacturer and series, ensuring consistent quality and performance characteristics.

The 93J2R4 substitute part is functionally equivalent in all electrical and mechanical parameters. Selection between these parts should be based on compliance requirements specific to the end application. Applications subject to RoHS regulations must use the 93J2R4E. Applications without RoHS compliance mandates may use either part based on availability and sourcing logistics.

Frequently Asked Questions (FAQ)

Q: Can the 93J2R4 be used in place of the 93J2R4E?

A: Yes, the 93J2R4 is a functional equivalent. Both parts share identical electrical specifications (2.4 Ohms ±5%, 3.25W), composition (Wirewound), package type (Axial), and thermal characteristics (±100ppm/°C). The primary difference is RoHS compliance status. Selection depends on regulatory requirements for your application.

Q: What are the critical parameters for substitution?

A: Resistance value, tolerance, power rating, composition type, package configuration, temperature coefficient, and safety features must all match exactly. The 93J2R4 meets all these criteria for the 93J2R4E.

Q: Are there dimensional differences between these parts?

A: Dimensions are nearly identical. The 93J2R4E measures 0.232" diameter, while the 93J2R4 measures 0.233" diameter. Both are 0.579" in length. These minimal variations do not affect PCB layout or mechanical fit in standard axial resistor footprints.

Q: Which part should I specify for new designs?

A: For designs subject to RoHS regulations or customer compliance requirements, specify the 93J2R4E. Both parts are Active status and available from the same manufacturer, ensuring long-term supply stability.

Q: Does RoHS compliance affect electrical performance?

A: No. RoHS compliance is a material composition and manufacturing process certification. It does not alter the electrical characteristics, thermal performance, or reliability of the component.
