Parameter Comparison

Engineering Selection Recommendations

The 1210R-682J is a direct functional equivalent to the obsolete 3225R-682J. Both components share identical electrical specifications across inductance, current rating, DC resistance, core material, and shielding configuration. Both maintain full compliance with ROHS3 and REACH requirements.

The primary distinction between the two parts is product status: the 3225R-682J is classified as Obsolete, while the 1210R-682J is Active. The 1210R-682J series offers superior supply chain availability, with 25,889 pieces in stock compared to 813 pieces of the obsolete variant.

Physical dimensions show minor variations within the 1210 (3225 Metric) package specification. The 1210R-682J exhibits a maximum seated height of 0.101" (2.57mm) compared to 0.094" (2.40mm) for the 3225R-682J. These dimensional differences remain within standard package tolerances and do not affect electrical performance or PCB assembly compatibility for standard surface mount applications.

The Q factor at 7.9MHz is 30 for the 1210R-682J compared to 25 for the 3225R-682J, indicating improved performance characteristics in the active substitute part.

For new designs and ongoing production requiring 6.8 µH unshielded ferrite inductors in the 1210 package format, the 1210R-682J is the appropriate selection based on active product status and equivalent electrical specifications.

Frequently Asked Questions (FAQ)

Q: Can the 1210R-682J directly replace the 3225R-682J in existing designs?

A: Yes. Both parts meet identical electrical specifications: 6.8 µH inductance at ±5% tolerance, 321 mA current rating, 1.8Ohm maximum DC resistance, ferrite core construction, and unshielded configuration. Both operate across -55°C to 125°C and comply with ROHS3 and REACH requirements. The parts are functionally equivalent for circuit operation.

Q: What are the physical compatibility considerations?

A: Both components use the 1210 (3225 Metric) surface mount package. The 1210R-682J has a maximum seated height of 0.101" (2.57mm) compared to 0.094" (2.40mm) for the 3225R-682J. This 0.007" (0.17mm) height difference is within standard package tolerances and does not affect standard PCB assembly processes or clearance requirements for typical applications.

Q: Why is the 1210R-682J preferred over the 3225R-682J?

A: The 1210R-682J carries Active product status with significantly higher inventory availability (25,889 pieces versus 813 pieces). The 3225R-682J is classified as Obsolete, making it unsuitable for new production or long-term supply chain planning. The 1210R-682J also demonstrates improved Q factor performance (30 @ 7.9MHz versus 25 @ 7.9MHz).

Q: Are there any electrical performance differences between these parts?

A: The core electrical specifications are identical. The 1210R-682J exhibits a higher Q factor at 7.9MHz (30 versus 25), indicating superior performance characteristics. Both parts maintain the same self-resonant frequency of 40MHz and are tested at 7.9MHz for inductance verification.

Q: What packaging options are available for the 1210R-682J?

A: The 1210R-682J is supplied in Cut Tape (CT) and Digi-Reel® formats, as well as standard Tape & Reel (TR) packaging. The 3225R-682J packaging format is not specified in the provided data.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the 3225R-682J and 1210R-682J are ROHS3 Compliant and REACH Unaffected. Both carry EAR99 ECCN classification and 8504.50.8000 HTSUS code.
