Parameter Comparison

Engineering Selection Recommendations

Both the 45JR15 and 45JR15E are active production parts from Ohmite with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: the 45JR15E is ROHS3 compliant, while the 45JR15 is RoHS non-compliant. Selection between these parts should be based on regulatory requirements applicable to the end application. For applications requiring RoHS3 compliance, the 45JR15E is the appropriate selection. Both parts maintain REACH Unaffected status and share identical ECCN and HTSUS classifications.

Frequently Asked Questions (FAQ)

Q: Can the 45JR15E directly replace the 45JR15 in existing designs?

A: Yes. The 45JR15E is a direct functional equivalent with identical resistance, tolerance, power rating, composition, package type, temperature coefficient, and physical dimensions. No circuit modifications are required.

Q: What is the difference between the 45JR15 and 45JR15E?

A: The primary difference is packaging and RoHS compliance. The 45JR15 is supplied in standard packaging and is RoHS non-compliant. The 45JR15E is supplied in bulk packaging and is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts are axial wirewound resistors with identical dimensions (0.343" Dia x 0.937" L), termination count (2), and electrical characteristics. They are mechanically and electrically interchangeable.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, specify the 45JR15E. For applications without RoHS compliance requirements, either part is acceptable based on availability and packaging preferences.

Q: Are both parts currently available?

A: Yes. Both the 45JR15 and 45JR15E are active production parts with current inventory availability.
