Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PM74SH-151M-RC are qualified based on the following criteria:

Primary Matching Parameters:

• Inductance value of 150 µH with ±20% tolerance
• Shielded construction
• Surface mount configuration
• Operating temperature range compatibility (-40°C minimum and 125°C maximum coverage)
• ROHS3 compliance and MSL 1 rating

Current Rating Consideration: Substitute parts must maintain a current rating equal to or greater than 530 mA to ensure equivalent or superior performance in the application circuit. DC resistance values up to 480 mOhm are acceptable within the tolerance band.

Mechanical Compatibility: All substitute parts utilize nonstandard surface mount packages with dimensions and heights compatible with the original part's 7.00mm x 7.00mm footprint and 4.80mm maximum seated height.

Parameter Comparison

Engineering Selection Recommendations

SRR7045-151M (Bourns Inc.): This substitute offers superior current handling at 800 mA with matching DC resistance of 480 mOhm Max, identical inductance, and equivalent temperature range. Both parts share Bourns manufacturing and identical electrical specifications except for increased current capacity. Product status is active with ROHS3 compliance and REACH unaffected designation.

P1167.154NLT and P1167.154NL (Pulse Electronics): These Pulse Electronics alternatives provide 520 mA current rating with slightly elevated DC resistance of 610 mOhm Max. Both parts maintain 150 µH inductance with ±20% tolerance and extended operating temperature to 130°C. Product status is active with ROHS3 compliance and REACH unaffected designation. The P1167.154NLT variant includes tape and reel packaging specification, while P1167.154NL packaging is unspecified.

All substitute parts maintain active product status, full regulatory compliance, and MSL 1 moisture sensitivity rating equivalent to the original PM74SH-151M-RC.

Frequently Asked Questions (FAQ)

Q: Can SRR7045-151M replace PM74SH-151M-RC in all applications? A: Yes. The SRR7045-151M matches all critical parameters: 150 µH inductance, ±20% tolerance, 480 mOhm Max DCR, shielded construction, and -40°C to 125°C operating range. The higher 800 mA current rating provides additional margin.

Q: What is the difference between P1167.154NLT and P1167.154NL? A: Both parts are electrically identical with 150 µH inductance, 520 mA current rating, and 610 mOhm Max DCR. The primary difference is packaging designation: P1167.154NLT specifies tape and reel (TR) packaging, while P1167.154NL packaging is unspecified.

Q: Are the Pulse Electronics parts suitable for the same circuit as the original Bourns part? A: The P1167 series parts are suitable substitutes with the following considerations: current rating is 520 mA versus 530 mA (10 mA lower), and DC resistance is 610 mOhm Max versus 480 mOhm Max (130 mOhm higher). These differences remain within acceptable tolerance for most applications requiring 150 µH inductance at surface mount.

Q: Do all substitute parts have the same physical footprint? A: All parts utilize 7.00mm x 7.00mm footprints with maximum seated heights of 4.80mm (PM74SH-151M-RC and SRR7045-151M) or 4.50mm (P1167 series). Verify PCB layout compatibility for the P1167 series due to slightly different dimensions.

Q: What is the temperature range difference between substitutes? A: PM74SH-151M-RC and SRR7045-151M operate -40°C to 125°C. P1167.154NLT and P1167.154NL extend to -40°C to 130°C, providing 5°C additional high-temperature margin.

Q: Are all parts ROHS3 compliant? A: Yes. PM74SH-151M-RC, SRR7045-151M, P1167.154NLT, and P1167.154NL are all ROHS3 compliant with MSL 1 rating and REACH unaffected status.
