Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25J22R is determined by strict equivalence across the following critical parameters:

• Resistance value: 22 Ohms
• Tolerance: ±5%
• Power rating: 5W
• Composition: Wirewound
• Package type: Axial
• Physical dimensions: 0.276" Dia x 1.016" L (7.00mm x 25.80mm)
• Temperature coefficient: ±30ppm/°C
• Features: Flame retardant coating and safety construction

The 25J22RE meets all substitution criteria as a direct equivalent, with identical electrical specifications and mechanical form factor. The primary distinction is packaging configuration and RoHS compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the 25J22R and 25J22RE are active production components from Ohmite's Series 20 line with identical electrical and mechanical specifications. Selection between these parts should be based on regulatory compliance requirements and packaging needs.

The 25J22R is suitable for applications where RoHS non-compliance is acceptable or where legacy component specifications are required. The 25J22RE provides ROHS3 compliance, making it the appropriate choice for designs subject to RoHS3 regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 export classification.

Packaging differs between the two parts: the 25J22R is supplied in standard packaging, while the 25J22RE is supplied in bulk packaging. This distinction affects procurement and handling procedures but does not impact electrical or mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can 25J22RE be used as a direct replacement for 25J22R in existing designs?

A: Yes. The 25J22RE is electrically and mechanically equivalent to the 25J22R. Both components have identical resistance values, tolerance, power rating, temperature coefficient, and physical dimensions. The primary difference is RoHS compliance status and packaging configuration.

Q: What is the difference between the packaging types listed for these parts?

A: The 25J22R uses standard packaging, while the 25J22RE uses bulk packaging. This affects how components are supplied and handled during procurement and assembly, but does not alter the component's electrical or mechanical characteristics.

Q: Does RoHS3 compliance affect component performance?

A: No. RoHS3 compliance is a regulatory designation indicating the component meets restrictions on hazardous substances. It does not change the electrical performance, power rating, or operating characteristics of the resistor.

Q: Are both parts suitable for high-temperature applications?

A: Both parts operate with a temperature coefficient of ±30ppm/°C. Operating temperature limits are not specified in the provided data. Consult the manufacturer's datasheet for specific operating temperature ranges.

Q: What is the significance of the flame retardant coating and safety features?

A: The flame retardant coating and safety construction are design features of the Series 20 wirewound resistor line. These features are present in both the 25J22R and 25J22RE and are maintained across all equivalent parts.
