Parameter Comparison

Engineering Selection Recommendations

Both the 25JR50 and 25JR50E are Active product status components manufactured by Ohmite. The primary distinction between these parts is packaging format and regulatory compliance status.

The 25JR50E offers ROHS3 compliance, making it suitable for applications subject to RoHS3 regulatory requirements. The 25JR50 is RoHS non-compliant and should be selected only when RoHS compliance is not a design constraint.

Both parts share identical electrical specifications, mechanical dimensions, and safety features. Selection between these variants depends on regulatory requirements and packaging preferences rather than functional performance.

Frequently Asked Questions (FAQ)

Q: Can the 25JR50E directly replace the 25JR50 in existing designs?

A: Yes. Both parts are electrically and mechanically identical with matching resistance values, tolerances, power ratings, physical dimensions, and safety features. The primary difference is RoHS compliance status and packaging format.

Q: What is the significance of the packaging difference between these parts?

A: The 25JR50 uses standard packaging while the 25JR50E is supplied in Bulk packaging. This distinction affects procurement quantities and handling but does not impact electrical or mechanical performance.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring ROHS3 compliance, specify the 25JR50E. For applications without RoHS compliance requirements, either part is acceptable based on availability and packaging needs.

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

A: No. Both parts share identical physical dimensions of 0.276" Dia x 1.016" L (7.00mm x 25.80mm) and identical electrical characteristics. No thermal or dimensional derating is required when substituting between these parts.

Q: Do both parts meet the same safety and feature requirements?

A: Yes. Both the 25JR50 and 25JR50E include flame retardant coating and safety features. Both are classified as wirewound resistors with identical composition and construction.
