• Saturation current (Isat): 550 mA minimum
• DC resistance: 500 mOhm maximum
• Core type: Ferrite drum core, shielded construction
• Mounting: Surface mount, nonstandard package
• Physical dimensions: 6.80mm x 6.80mm footprint, 3.00mm maximum height
• Operating temperature range: -40°C to 125°C
• Regulatory compliance: ROHS3 compliant, REACH unaffected

The SRR6028-101Y meets all specified electrical and mechanical parameters for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both PM628S-101-RC and SRR6028-101Y are Active status products manufactured by Bourns Inc. and maintain full compliance with ROHS3 and REACH requirements. Selection between these parts is based on application-specific frequency response requirements. The PM628S-101-RC exhibits a self-resonant frequency of 7 MHz, while the SRR6028-101Y operates at 14 MHz. All other electrical specifications, mechanical dimensions, and regulatory certifications are equivalent. Both components are suitable for direct substitution where frequency characteristics are compatible with circuit design parameters.

Frequently Asked Questions (FAQ)

Q: Can SRR6028-101Y replace PM628S-101-RC in any application?

A: Direct substitution is valid when the application does not depend on the specific self-resonant frequency characteristic. The PM628S-101-RC operates at 7 MHz self-resonant frequency, while SRR6028-101Y operates at 14 MHz. All other electrical and mechanical parameters are equivalent.

Q: Are the physical footprints identical?

A: Yes. Both components share identical dimensions of 6.80mm x 6.80mm with a maximum seated height of 3.00mm, enabling direct PCB layout compatibility.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both PM628S-101-RC and SRR6028-101Y are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level).

Q: What is the critical difference between these two inductors?

A: The self-resonant frequency differs: PM628S-101-RC at 7 MHz versus SRR6028-101Y at 14 MHz. All DC electrical parameters, current ratings, and thermal specifications are identical.

Q: Are both parts currently available?

A: Both components maintain Active product status. Inventory availability should be confirmed with the supplier for current stock levels.
