Engineering Selection Recommendations

The SRP7030-6R8M is a direct functional equivalent to the obsolete CDEP63MENP-6R8MC. Both components maintain identical inductance values, tolerance specifications, and operating temperature ranges. The substitute part is manufactured by Bourns Inc., an active product line with confirmed inventory availability.

Compliance Status: Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8504.50.4000), ensuring regulatory equivalence.

Performance Advantages of SRP7030-6R8M:

Active product status ensures long-term availability and supply chain continuity
Current rating of 4.5 A exceeds the original 2.5 A specification
DC resistance of 60 mOhm Max is superior to the original 85.5 mOhm Max
Saturation current of 6.0 A is comparable to the original 6.1 A

Physical Considerations: The SRP7030-6R8M exhibits slightly larger dimensions (7.80mm x 7.00mm vs. 7.25mm x 6.80mm) and marginally increased height (3.20mm vs. 3.00mm). PCB layout verification is required to confirm mechanical fit within existing designs.

Frequently Asked Questions (FAQ)

Q: Can the SRP7030-6R8M directly replace the CDEP63MENP-6R8MC without circuit modifications?

A: The SRP7030-6R8M provides electrical equivalence across all critical parameters: identical inductance value, tolerance, operating temperature range, and shielding configuration. However, physical dimensions differ slightly. PCB layout must be verified to confirm the substitute component fits within the allocated space. No circuit modifications are required if mechanical fit is confirmed.

Q: What is the significance of the improved DC resistance in the substitute part?

A: The SRP7030-6R8M features a maximum DC resistance of 60 mOhm compared to 85.5 mOhm in the original part. Lower DC resistance reduces resistive losses and heat generation during operation, improving overall circuit efficiency. This enhancement is beneficial for applications operating at or near the 2.5 A current rating.

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

A: Both components are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity ratings. Both are REACH unaffected and classified under identical ECCN and HTSUS codes. No compliance differences exist between the parts.

Q: Why is the substitute part rated for 4.5 A when the original is only 2.5 A?

A: The higher current rating of the SRP7030-6R8M reflects improved thermal and magnetic design in the active product line. This does not affect substitution compatibility; the part operates safely at the original 2.5 A specification and provides additional design margin for future applications.

Q: What packaging format is available for the SRP7030-6R8M?

A: The SRP7030-6R8M is supplied in Tape & Reel (TR) packaging format, standard for surface mount production environments. Confirm packaging compatibility with your assembly process requirements.

Q: How do the saturation current specifications compare?

A: The original CDEP63MENP-6R8MC has a saturation current (Isat) of 6.1 A, while the SRP7030-6R8M is rated at 6.0 A. Both values are comparable and exceed the nominal 2.5 A operating current, ensuring adequate magnetic performance margin in typical applications.
