Frequently Asked Questions (FAQ)

Q: What makes SDS680R-106M a direct substitute for ASPI-0403S-103M?

A: The substitute part matches all critical electrical parameters: 10 mH inductance, 20 mA current rating, and 32.8 Ohm DC resistance. Both components share identical mounting type (surface mount), RoHS compliance status, and moisture sensitivity classification.

Q: Are there any physical dimension differences between these parts?

A: The SDS680R-106M specifies physical dimensions of 0.260" L x 0.175" W (6.60mm x 4.45mm) with a maximum seated height of 0.115" (2.92mm). The original part dimensions are not provided in the specification. PCB layout verification is recommended to confirm footprint compatibility.

Q: What is the inductance tolerance of the substitute part?

A: The SDS680R-106M carries an inductance tolerance of ±20%. The original part tolerance specification is not provided. Circuit design margins should account for this tolerance range.

Q: Does the substitute part maintain the same operating temperature range?

A: The SDS680R-106M operates across -40°C to 85°C. The original part operating temperature range is not specified. The substitute part range is suitable for standard industrial and commercial applications.

Q: Is the substitute part available in the same packaging format?

A: The SDS680R-106M is supplied in Tape & Reel (TR) format. Both components are surface mount types compatible with automated assembly processes.
