Substitute Part Grouping Explanation

Substitution eligibility for the R5J15R is determined by strict equivalence across the following critical parameters:

• Resistance value: 15 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package configuration: Radial Lead
• Physical dimensions: 0.625" L x 0.344" W with maximum seated height of 0.516"
• Temperature coefficient: ±260ppm/°C
• Features: Flame Retardant Coating, Safety construction

The R5J15RE meets all electrical and mechanical requirements for direct substitution. Both parts are manufactured by Ohmite within the PC-58 series and share identical resistance, tolerance, power rating, composition, and physical specifications. The primary difference lies in packaging format and compliance certification status.

Parameter Comparison

Engineering Selection Recommendations

Both R5J15R and R5J15RE are active production parts with full inventory availability. Selection between these equivalents should be based on compliance and packaging requirements:

The R5J15RE is ROHS3 compliant with MSL rating of 1 (Unlimited), making it suitable for applications subject to RoHS3 regulatory requirements or environments with extended storage conditions. The R5J15R remains non-compliant with RoHS standards but is available for applications without such constraints.

Packaging format differs between the two parts: R5J15R is supplied in standard packaging, while R5J15RE is supplied in bulk format. Bulk packaging may be preferred for high-volume production runs or inventory consolidation.

Both parts maintain identical electrical performance, mechanical fit, and thermal characteristics. Selection does not impact circuit functionality or board layout.

Frequently Asked Questions (FAQ)

Q: Can R5J15RE be used as a direct replacement for R5J15R in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical resistance, tolerance, power rating, composition, physical dimensions, and thermal characteristics. No circuit redesign or board layout modification is required.

Q: What is the difference between R5J15R and R5J15RE?

A: The primary differences are RoHS compliance status and packaging format. R5J15RE is ROHS3 compliant with MSL rating 1, while R5J15R is RoHS non-compliant. R5J15RE is supplied in bulk packaging; R5J15R in standard packaging. Electrical and mechanical specifications are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements and supply chain preferences. For applications requiring RoHS3 compliance, R5J15RE is the appropriate choice. For applications without compliance constraints, either part is suitable based on packaging and inventory availability.

Q: Are there any thermal or performance differences between these parts?

A: No. Both parts have identical temperature coefficients (±260ppm/°C), power ratings (5W), and thermal characteristics. Performance in circuit operation is equivalent.

Q: What does MSL rating 1 (Unlimited) mean for R5J15RE?

A: MSL 1 indicates the component has unlimited shelf life under standard storage conditions. This provides flexibility for inventory management and extended storage without degradation risk.

Q: Can these parts be mixed in the same production batch?

A: Yes. Since electrical and mechanical specifications are identical, R5J15R and R5J15RE can be used interchangeably within the same assembly without functional impact. However, compliance documentation should reflect the specific part number used.
