Substitute Part Grouping Explanation

Substitution eligibility for the 43J15R is determined by strict equivalence across the following critical parameters:

• Resistance value: 15 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Wirewound (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Physical dimensions: 0.220" Dia x 0.594" L (exact match required)

The substitute part 43J15RE meets all electrical and mechanical parameters required for direct substitution. Differences exist only in packaging configuration (bulk vs. standard), RoHS compliance status, and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both the 43J15R and 43J15RE are electrically and mechanically equivalent for circuit applications requiring a 15 Ohm, 3W axial wirewound resistor. Selection between these parts should be based on the following criteria:

43J15R is appropriate for applications where RoHS non-compliant components are acceptable and standard packaging is preferred. This part maintains active production status.

43J15RE is appropriate for applications requiring RoHS compliance, higher inventory availability, or bulk packaging configurations. This part provides an operating temperature range specification of -55°C to 275°C and demonstrates RoHS compliance certification.

Both parts share identical electrical performance characteristics, physical dimensions, and mechanical compatibility. The choice between them depends on regulatory requirements, packaging needs, and supply chain considerations rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can 43J15RE be used as a direct replacement for 43J15R in existing designs?

A: Yes. Both parts are electrically and mechanically identical in resistance value, tolerance, power rating, composition, package type, and physical dimensions. They are functionally interchangeable in circuit applications.

Q: What is the difference between the 43J15R and 43J15RE?

A: The primary differences are packaging configuration (standard vs. bulk), RoHS compliance status (non-compliant vs. compliant), and inventory availability. Electrical and mechanical specifications are identical.

Q: Does the RoHS compliance difference affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental regulations, not electrical performance. Both parts deliver identical circuit functionality.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts measure 0.220" diameter by 0.594" length (5.60mm x 15.10mm) and are compatible with identical PCB layouts and mechanical assemblies.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS compliance, select 43J15RE. For applications where RoHS compliance is not required, either part is suitable based on availability and packaging preference.

Q: Is the operating temperature range a limiting factor for substitution?

A: The 43J15RE specifies an operating range of -55°C to 275°C. The 43J15R does not provide this specification. Both parts are suitable for standard industrial and commercial temperature environments. Applications requiring operation outside the specified range for 43J15RE should be evaluated separately.
