Substitute Part Grouping Explanation

Substitution eligibility for the 23J50R is determined by strict equivalence across the following critical parameters:

• Resistance value: 50 Ohms
• Tolerance: ±5%
• Power rating: 3W
• Composition: Wirewound
• Package configuration: Axial
• Temperature coefficient: ±30ppm/°C
• Physical dimensions: 0.220" Dia x 0.516" L
• Termination count: 2
• Features: Flame Retardant Coating, Safety

The Ohmite 23J50RE meets all electrical and mechanical requirements for direct substitution. Differences in RoHS compliance status and moisture sensitivity classification do not affect functional equivalence but may influence selection based on end-application regulatory requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the 23J50R and 23J50RE are Active status components suitable for direct substitution based on electrical and mechanical equivalence. Selection between these parts should be determined by application-specific compliance requirements:

The 23J50RE is RoHS Compliant with defined moisture sensitivity classification (MSL 1), making it the preferred choice for applications subject to RoHS directives or requiring documented environmental specifications. The 23J50R, while RoHS non-compliant, remains suitable for applications without such regulatory constraints. Both components carry identical electrical performance characteristics and physical form factors, ensuring functional interchangeability in circuit design.

Frequently Asked Questions (FAQ)

Q: Can the 23J50RE replace the 23J50R in all applications?

A: Yes, from an electrical and mechanical standpoint. The 23J50RE is electrically and dimensionally identical to the 23J50R. Selection should be based on compliance requirements specific to your application. If RoHS compliance is required, the 23J50RE is the appropriate choice.

Q: What is the significance of the RoHS compliance difference?

A: RoHS compliance indicates adherence to the Restriction of Hazardous Substances directive. The 23J50RE meets these requirements, while the 23J50R does not. Applications destined for markets with RoHS mandates must use the 23J50RE.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the 23J50R and 23J50RE share identical axial package dimensions of 0.220" diameter by 0.516" length (5.60mm x 13.10mm), ensuring compatibility with existing PCB layouts and mechanical assemblies.

Q: What does MSL 1 (Unlimited) mean for the 23J50RE?

A: Moisture Sensitivity Level 1 indicates the lowest moisture sensitivity classification. This means the component can be stored indefinitely without special moisture control measures, simplifying inventory management and logistics.

Q: Are there any performance differences in temperature coefficient or tolerance?

A: No. Both parts maintain identical temperature coefficient specifications of ±30ppm/°C and tolerance of ±5%, ensuring equivalent thermal stability and accuracy across operating conditions.
