Frequently Asked Questions (FAQ)

Q: Can the SRR1806-151M be used as a direct replacement for the PM5022S-151M-RC?

A: Yes. The SRR1806-151M is electrically and mechanically equivalent to the PM5022S-151M-RC across all specified parameters, including inductance, current rating, DC resistance, frequency characteristics, physical dimensions, and compliance certifications.

Q: Are there any differences in the package or mounting requirements?

A: No. Both parts use identical surface mount packaging with tape and reel delivery, the same footprint dimensions of 0.720" L x 0.551" W, and maximum seated height of 0.280". PCB layout and assembly processes require no modification.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both the PM5022S-151M-RC and SRR1806-151M are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity level) ratings.

Q: What is the difference between the PM5022S and SRR1806 series designations?

A: The series designation reflects the product line within Bourns Inc. The PM5022S and SRR1806 are distinct series, but the specific part numbers PM5022S-151M-RC and SRR1806-151M share identical electrical and mechanical specifications for this 150 µH inductor configuration.

Q: Are there any thermal or frequency performance differences?

A: No. Both parts operate across the same temperature range of -40°C to 125°C and exhibit identical Q factor (39 @ 796 kHz) and self-resonant frequency (4.3 MHz) characteristics.
