Substitute Part Grouping Explanation

Substitution of the PM2110-102K is determined by strict equivalence across the following electrical and mechanical parameters:

• Inductance value: 1 mH with ±10% tolerance
• Current rating: 1.9 A minimum
• DC resistance: 244 mOhm maximum
• Core material: Iron
• Shielding configuration: Unshielded
• Mounting technology: Surface mount
• Physical dimensions: 30.50 mm × 25.40 mm × 15.24 mm (max height)
• Operating temperature range: -55°C to 105°C

The PM2110-102K-RC is identified as a direct substitute based on identical electrical specifications and mechanical compatibility within the PM2110 series.

Parameter Comparison

Engineering Selection Recommendations

The PM2110-102K-RC is the direct equivalent for the obsolete PM2110-102K. Both components share identical electrical and mechanical specifications, ensuring pin-for-pin and form-factor compatibility. The primary distinction is product status: PM2110-102K-RC is active and available for new procurement, while PM2110-102K is obsolete.

For new designs or component replenishment, PM2110-102K-RC is the appropriate selection. The substitute part carries ROHS3 compliance, providing enhanced environmental and regulatory alignment compared to the non-compliant original part. Both components maintain identical operating temperature ranges and physical dimensions, eliminating the need for PCB layout modifications.

Frequently Asked Questions (FAQ)

Q: Can PM2110-102K-RC be used as a direct replacement for PM2110-102K?

A: Yes. Both parts are electrically and mechanically identical, with matching inductance (1 mH ±10%), current rating (1.9 A), DC resistance (244 mOhm max), core material (iron), shielding (unshielded), and physical dimensions (30.50 mm × 25.40 mm × 15.24 mm max height). No circuit modifications or PCB redesign is required.

Q: What is the difference between PM2110-102K and PM2110-102K-RC?

A: The primary differences are product status and compliance. PM2110-102K is obsolete, while PM2110-102K-RC is active. PM2110-102K-RC is ROHS3 compliant, whereas PM2110-102K is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: PM2110-102K uses standard packaging, while PM2110-102K-RC is supplied in bulk packaging. Both maintain the same nonstandard package case type and physical dimensions suitable for surface mount assembly.

Q: What operating temperature range applies to both parts?

A: Both PM2110-102K and PM2110-102K-RC operate across -55°C to 105°C, ensuring compatibility in equivalent thermal environments.

Q: Is PCB layout modification necessary when substituting PM2110-102K-RC for PM2110-102K?

A: No. Identical physical dimensions and mounting type (surface mount) eliminate the need for layout changes. Direct substitution on existing PCBs is feasible.
