Substitute Part Grouping Explanation

Substitution eligibility for the PM2110-331K is determined by strict equivalence across the following critical parameters:

• Inductance value: 330 µH with ±10% tolerance
• Current rating: 3.2 A minimum
• DC resistance: 90 mOhm maximum
• Core material: Iron
• Shielding configuration: Unshielded
• Inductor type: Toroidal
• Operating temperature range: -55°C to 105°C
• Mounting configuration: Surface mount, nonstandard package
• Physical dimensions: 30.50 mm × 25.40 mm × 15.24 mm (max height)

The PM2110-331K-RC qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The PM2110-331K-RC is the direct equivalent substitute for the obsolete PM2110-331K. Both components share identical electrical specifications and physical dimensions, ensuring drop-in compatibility at the circuit level.

The primary distinction between these parts is product status and regulatory compliance. The PM2110-331K-RC carries active product status from Bourns Inc. and meets ROHS3 compliance requirements, whereas the original PM2110-331K is obsolete and RoHS non-compliant. For new designs and ongoing production requiring regulatory compliance, the PM2110-331K-RC is the appropriate selection.

Both parts maintain equivalent performance across all functional parameters: 330 µH inductance, 3.2 A current rating, 90 mOhm maximum DC resistance, and -55°C to 105°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the PM2110-331K-RC be used as a direct replacement for the PM2110-331K?

A: Yes. The PM2110-331K-RC is electrically and mechanically identical to the PM2110-331K. All inductance, current, resistance, and dimensional specifications are equivalent, enabling direct substitution in existing circuit designs.

Q: What is the primary reason to transition from PM2110-331K to PM2110-331K-RC?

A: The PM2110-331K is obsolete and RoHS non-compliant. The PM2110-331K-RC is an active product that meets ROHS3 compliance standards, making it the appropriate choice for current production and applications requiring regulatory adherence.

Q: Are there any differences in physical dimensions between these parts?

A: No. Both the PM2110-331K and PM2110-331K-RC share identical dimensions: 30.50 mm length × 25.40 mm width × 15.24 mm maximum height. PCB layout and mechanical mounting are fully compatible.

Q: What is the difference between standard and bulk packaging for these inductors?

A: Packaging designation indicates the form in which components are supplied. Both packaging types contain the same electrical component; the difference is in quantity and presentation format for inventory and assembly operations.

Q: Are the electrical performance characteristics identical between PM2110-331K and PM2110-331K-RC?

A: Yes. Both parts deliver 330 µH inductance with ±10% tolerance, support 3.2 A current rating, and maintain 90 mOhm maximum DC resistance across the -55°C to 105°C operating temperature range.
