Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PM74SH-560M-RC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 56 µH (exact match required)
• Inductance tolerance: ±20% (matching tolerance band)
• Shielding: Shielded configuration
• Mounting type: Surface mount
• Current rating: Minimum 850 mA
• DC resistance: Maximum 200 mOhm (lower values acceptable)

Secondary Compatibility Factors:

• Operating temperature range: Minimum -40°C to 125°C coverage
• RoHS3 compliance status
• Package classification: Nonstandard surface mount

The substitute part P1167.563NLT from Pulse Electronics meets these criteria with equivalent inductance, shielding, and mounting characteristics, while maintaining compatible current handling and thermal specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the PM74SH-560M-RC and P1167.563NLT are active production components with ROHS3 compliance and REACH unaffected status, making them suitable for current regulatory environments. The PM74SH-560M-RC offers lower DC resistance (200 mOhm max) and higher self-resonant frequency (11 MHz), providing advantages in applications sensitive to resistive losses and high-frequency performance. The P1167.563NLT provides higher current saturation capability (860 mA) and extended operating temperature range to 130°C, with a lower profile package (4.50 mm height), making it preferable for thermally demanding or space-constrained applications. Selection should be based on specific circuit requirements regarding power dissipation, frequency response, and thermal environment.

Frequently Asked Questions (FAQ)

Q: Can P1167.563NLT be used as a direct replacement for PM74SH-560M-RC?

A: Yes, within the constraints of the application. Both components share identical inductance (56 µH), tolerance (±20%), shielding configuration, and mounting type. The substitute has slightly higher DC resistance (270 mOhm vs. 200 mOhm max) and lower self-resonant frequency (9.2 MHz vs. 11 MHz), which may affect circuit performance in applications with stringent loss or frequency response requirements.

Q: What is the impact of the 70 mOhm difference in DC resistance?

A: The P1167.563NLT has 70 mOhm higher maximum DC resistance. In circuits where resistive losses are critical, this difference may result in increased power dissipation. For typical filtering and energy storage applications, this variance is generally acceptable within the ±20% inductance tolerance band.

Q: Are the dimensional differences significant?

A: The P1167.563NLT is slightly larger in footprint (7.54 mm vs. 7.00 mm) but has a lower profile (4.50 mm vs. 4.80 mm). PCB layout compatibility should be verified, particularly for high-density designs. The lower height may provide advantages in space-constrained applications.

Q: Do both parts meet the same compliance standards?

A: Yes. Both PM74SH-560M-RC and P1167.563NLT are ROHS3 compliant, REACH unaffected, and classified under the same ECCN category (EAR99), ensuring equivalent regulatory compliance for most applications.

Q: What is the operating temperature consideration?

A: The PM74SH-560M-RC operates from -40°C to 125°C, while the P1167.563NLT extends to 130°C. For applications operating near the upper thermal limit, the substitute provides a 5°C margin. Both meet standard industrial temperature requirements.
