Frequently Asked Questions (FAQ)

Q: Can PM1608S-102M-RC be used as a direct replacement for UP0.4SC-102-R?

A: Yes. Both parts meet identical electrical specifications: 1 mH inductance (±20%), 150 mA current rating, 3.4 Ohm maximum DC resistance, 40 Q factor at 100 kHz, and 2 MHz self resonant frequency. Both are shielded surface mount components with MSL 1 rating. The PM1608S-102M-RC offers extended temperature range (-55°C to 125°C) and RoHS3 compliance.

Q: What is the difference between the Eaton UP0.4SC-102-R and the Bourns SRR6603-102ML?

A: Both parts meet identical electrical specifications and are shielded surface mount inductors. The SRR6603-102ML features ferrite drum core construction, extended operating temperature range (-55°C to 125°C), specified saturation current of 45 mA, and RoHS3 compliance. The UP0.4SC-102-R operates from -40°C to 125°C and uses wirewound construction.

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

A: The UP0.4SC-102-R measures 0.260" L x 0.175" W x 0.115" H (6.60mm x 4.45mm x 2.92mm). Both Bourns substitutes (PM1608S-102M-RC and SRR6603-102ML) measure 0.260" L x 0.173" W x 0.118" H (6.60mm x 4.40mm x 3.00mm). These dimensions are within nonstandard package classification and are compatible with standard surface mount assembly equipment.

Q: Which substitute part has the best supply availability?

A: The SRR6603-102ML from Bourns has the highest inventory level at 6900 pieces in stock, compared to 1461 pieces for PM1608S-102M-RC and 832 pieces for the original UP0.4SC-102-R.

Q: Do all three parts meet RoHS requirements?

A: Yes. The UP0.4SC-102-R is RoHS Compliant. Both Bourns substitutes (PM1608S-102M-RC and SRR6603-102ML) are RoHS3 Compliant with REACH unaffected status, providing enhanced environmental compliance documentation.

Q: Can these parts be used in applications requiring operation below -40°C?

A: The UP0.4SC-102-R is rated for -40°C minimum. Both Bourns substitutes (PM1608S-102M-RC and SRR6603-102ML) are rated for -55°C minimum, making them suitable for applications requiring extended low-temperature operation.
