ASPI-0403S-103M-T Equivalent & Substitute Parts

Part Overview

The ASPI-0403S-103M-T is a 10 mH shielded wirewound inductor manufactured by Abracon LLC, rated for 20 mA maximum current with a DC resistance of 32.8Ohm maximum. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and production continuity. The part operates across the industrial temperature range of -40°C to 85°C and is mounted as a surface mount device in a nonstandard package measuring 6.60mm x 4.45mm x 2.92mm (max height).

Key Parameters

Substitute Part Grouping Explanation

The SDS680R-106M from API Delevan Inc. qualifies as a direct substitute based on the following matched electrical and mechanical parameters:

• Inductance value: 10 mH (identical)
• Inductance tolerance: ±20% (identical)
• Current rating: 20 mA (identical)
• DC resistance: 32.8Ohm maximum (identical)
• Shielding: Shielded (identical)
• Surface mount configuration (identical)
• Package dimensions: 6.60mm x 4.45mm x 2.92mm max height (identical)
• Operating temperature range: -40°C to 85°C (identical)
• Inductance test frequency: 100 kHz (identical)
• RoHS3 compliance (identical)
• MSL 1 rating (identical)

The substitute differs in core material composition (drum core ferrite versus standard wirewound) and self-resonant frequency specification (800 kHz provided), but these differences do not affect functional equivalence within the specified electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The SDS680R-106M is the qualified substitute for the obsolete ASPI-0403S-103M-T. Selection is based on:

• Complete electrical parameter equivalence across inductance, current rating, and DC resistance specifications
• Identical physical footprint and height constraints for direct PCB layout compatibility
• Matching operating temperature range and inductance test frequency
• Active product status with established supply chain availability (24,386 pcs in stock versus 803 pcs for the obsolete part)
• Equivalent regulatory compliance: both ROHS3 compliant, REACH unaffected, and MSL 1 rated
• Identical moisture sensitivity classification ensuring equivalent handling and storage requirements

The substitute part is suitable for direct replacement in new production and redesign activities where the ASPI-0403S-103M-T is no longer procurable.

Frequently Asked Questions (FAQ)

Q: Can the SDS680R-106M be used as a direct replacement without circuit modification?

A: Yes. The SDS680R-106M matches all critical electrical parameters (inductance, tolerance, current rating, DC resistance) and physical dimensions of the ASPI-0403S-103M-T. No circuit redesign is required.

Q: What is the difference between the wirewound and drum core construction?

A: Both configurations are wirewound inductors. The SDS680R-106M uses a drum core ferrite structure, while the ASPI-0403S-103M-T uses standard wirewound construction. Both deliver identical electrical performance within the specified parameters.

Q: Are there packaging differences between these parts?

A: Both parts use nonstandard surface mount packages with identical dimensions (6.60mm x 4.45mm x 2.92mm max height). The SDS680R-106M is supplied in tape and reel format, while the ASPI-0403S-103M-T packaging format is not specified. Verify tape and reel compatibility with your assembly process.

Q: Do these parts have the same regulatory compliance?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity ratings. No compliance differences exist.

Q: Why is the ASPI-0403S-103M-T marked obsolete?

A: The ASPI-0403S-103M-T is classified as obsolete by the manufacturer. The SDS680R-106M from API Delevan Inc. is an active product with established supply availability, making it the recommended alternative for ongoing production support.
