Substitute Part Grouping Explanation

Substitution eligibility for the SCRH5D28R-680 is determined by the following critical parameters:

Inductance value must fall within the ±30% tolerance band (47.6 µH to 88.4 µH). Current rating must support the application's maximum continuous current requirement. DC resistance must not exceed the specified maximum to maintain circuit performance and thermal characteristics. Saturation current must be sufficient for transient conditions. Physical dimensions must accommodate the PCB layout constraints. Shielding requirement must be maintained to prevent electromagnetic interference. Surface mount packaging and nonstandard case format must be preserved. Operating temperature range must encompass the application environment. RoHS3 compliance and MSL rating must be maintained for manufacturing and reliability standards.

Engineering Selection Recommendations

The SD6030-680-R from Eaton - Electronics Division qualifies as a direct substitute for the SCRH5D28R-680. Both components maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory alignment. The substitute part demonstrates equivalent electrical performance across all critical parameters: inductance value remains within the specified ±30% tolerance band, current ratings are functionally equivalent at 920 mA versus 940 mA, and DC resistance remains within acceptable limits at 355 mOhm maximum. Physical compatibility is confirmed through matched surface mount packaging, identical height specifications, and compatible footprint dimensions. The substitute's saturation current of 520 mA exceeds the original specification of 480 mA, providing additional margin for transient conditions. Both parts maintain identical operating temperature ranges and moisture sensitivity ratings, supporting seamless integration into existing manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can the SD6030-680-R be used as a direct replacement for the SCRH5D28R-680 on existing PCBs?

A: Yes. Both components are surface mount inductors with identical height (3.00 mm maximum) and compatible footprint dimensions (6.30 x 6.20 mm versus 6.00 x 6.00 mm). The substitute's slightly smaller footprint does not prevent PCB placement. Electrical parameters remain within specification tolerances.

Q: What is the inductance tolerance range for both parts?

A: Both the SCRH5D28R-680 and SD6030-680-R carry ±30% inductance tolerance. This establishes an acceptable inductance range of 47.6 µH to 88.4 µH for circuit design purposes.

Q: Are there differences in current handling capability?

A: The SCRH5D28R-680 is rated for 940 mA continuous current, while the SD6030-680-R is rated for 920 mA. This 20 mA difference is negligible for most applications. The substitute's saturation current of 520 mA exceeds the original's 480 mA specification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, carry MSL rating 1 (Unlimited), and maintain REACH Unaffected status. Manufacturing and storage requirements are identical.

Q: What is the DC resistance difference between these parts?

A: The SCRH5D28R-680 specifies 351 mOhm maximum DC resistance, while the SD6030-680-R specifies 355 mOhm maximum. This 4 mOhm difference represents approximately 1.1% variation and remains within acceptable engineering tolerances for most circuit applications.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both components operate across -40°C to 125°C, supporting identical thermal requirements and environmental specifications.
