Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM104SH-221-RC is determined by strict equivalence across the following critical parameters:

Inductance value must be 220 µH with ±30% tolerance. Current rating must support minimum 650 mA. DC resistance must not exceed 565 mOhm. Shielding configuration must be shielded. Core material must be ferrite. Package dimensions must match 10.00mm x 10.00mm footprint with maximum seated height of 4.10mm. Mounting type must be surface mount. Operating temperature range must encompass -40°C to 125°C. RoHS compliance status must be ROHS3 or equivalent.

The SRU1038-221Y meets all substitution criteria and is classified as a direct equivalent part.

Frequently Asked Questions (FAQ)

Q: Can SRU1038-221Y be used as a direct replacement for PM104SH-221-RC?

A: Yes. Both parts are manufactured by Bourns Inc. and share identical electrical specifications (220 µH inductance, 650 mA current rating, 565 mOhm DCR), shielding configuration, core material, package dimensions (10.00mm x 10.00mm), and operating temperature range (-40°C to 125°C). Direct substitution is supported without circuit modification.

Q: Are there any compliance or certification differences between these parts?

A: No. Both PM104SH-221-RC and SRU1038-221Y carry identical ROHS3 compliance, REACH unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating.

Q: What determines substitution eligibility for this inductor category?

A: Substitution requires matching inductance value (220 µH ±30%), current rating (650 mA minimum), DC resistance (565 mOhm maximum), shielding type (shielded), core material (ferrite), package footprint (10.00mm x 10.00mm), mounted height (4.10mm maximum), and operating temperature range (-40°C to 125°C).

Q: Are the package dimensions identical between PM104SH-221-RC and SRU1038-221Y?

A: Yes. Both components use identical surface mount package dimensions of 10.00mm length x 10.00mm width with maximum seated height of 4.10mm, ensuring PCB layout compatibility.

Q: What is the difference between the PM104SH and SRU1038 series designations?

A: PM104SH and SRU1038 are different series designations from Bourns Inc. The SRU1038-221Y represents an equivalent product line offering the same electrical and mechanical specifications as the PM104SH-221-RC.
