Parameter Comparison

Engineering Selection Recommendations

The 1210R-104J is a direct functional equivalent to the 3225R-104J. Both components share identical electrical specifications, core material composition, package format, and environmental operating range. The substitute part carries Active product status, ensuring ongoing availability and supply chain support.

The 1210R-104J demonstrates a higher Q factor (30 @ 2.5 MHz versus 25 @ 2.5 MHz), indicating improved efficiency characteristics. This represents a performance enhancement rather than a deviation from specification.

Both parts maintain full RoHS3 compliance and REACH Unaffected regulatory status. Moisture sensitivity classification is identical at MSL Level 1, requiring no special handling modifications during assembly or storage.

The transition from the Obsolete 3225R-104J to the Active 1210R-104J is supported by identical mechanical dimensions within the 1210 (3225 Metric) package specification, ensuring direct PCB footprint compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 1210R-104J be used as a direct replacement for the 3225R-104J without PCB redesign?

A: Yes. Both parts utilize the 1210 (3225 Metric) package format with compatible surface mount footprints. The dimensional specifications support direct substitution on existing PCB layouts.

Q: Are there electrical performance differences between these parts?

A: The electrical specifications are equivalent. The 1210R-104J exhibits a higher Q factor (30 versus 25 @ 2.5 MHz), which indicates superior efficiency. This does not constitute a deviation from the required 100 µH inductance, 120 mA current rating, or 13 Ohm maximum DC resistance.

Q: What is the significance of the product status change from Obsolete to Active?

A: The Active status of the 1210R-104J ensures continued manufacturing, inventory availability, and long-term supply chain support. This eliminates the risk of component discontinuation associated with the Obsolete 3225R-104J.

Q: Are compliance certifications maintained in the substitute part?

A: Yes. The 1210R-104J maintains identical RoHS3 compliance, REACH Unaffected status, and MSL Level 1 moisture sensitivity rating. No changes to assembly, storage, or handling procedures are required.

Q: What packaging format is available for the 1210R-104J?

A: The 1210R-104J is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount production environments.
