Parameter Comparison

Engineering Selection Recommendations

Both the 15FR030 and 15FR030E are active production parts from Ohmite with identical electrical and mechanical specifications. The primary distinction is regulatory compliance: the 15FR030E meets ROHS3 requirements, while the 15FR030 is RoHS non-compliant. Selection between these parts should be based on application regulatory requirements. Both parts maintain REACH Unaffected status and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can the 15FR030E be used as a direct replacement for the 15FR030?

A: Yes. Both parts share identical resistance, tolerance, power rating, temperature coefficient, operating temperature range, composition, features, and physical dimensions. Direct substitution is electrically and mechanically compatible.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The 15FR030E is ROHS3 compliant, while the 15FR030 is RoHS non-compliant. All electrical and mechanical parameters are identical.

Q: Are there packaging differences between 15FR030 and 15FR030E?

A: The 15FR030 is supplied in standard packaging, while the 15FR030E is supplied in bulk packaging. Both maintain the same axial form factor and physical dimensions.

Q: Which part should I select for new designs?

A: Selection depends on regulatory requirements applicable to your application. For applications requiring RoHS3 compliance, specify 15FR030E. For applications without RoHS requirements, either part is suitable.

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

A: Yes. Both parts operate across -55°C to 275°C, supporting high-temperature circuit implementations.
