SCRH127-100 Equivalent & Substitute Parts

Part Overview

The SCRH127-100 is a 10 µH shielded surface mount inductor manufactured by Signal Transformer, designed for applications requiring fixed inductance with moderate current handling. This component is rated for 5.67 A continuous current with a maximum DC resistance of 21.6 mOhm and operates across the industrial temperature range of -40°C to 125°C. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility allow direct replacement in circuit designs.

Substitute Part Grouping Explanation

The CDRH127NP-100MC from Sumida America Components Inc. qualifies as a substitute based on the following alignment of critical parameters:

Inductance specifications match exactly at 10 µH with identical ±20% tolerance. Both components feature shielded construction and surface mount technology. DC resistance is identical at 21.6 mOhm maximum. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). The saturation current of the substitute (5.4 A) is within the operational envelope of the main part's 5.67 A rating. Physical dimensions are comparable, with the substitute measuring 12.00mm × 12.00mm versus the main part's 12.50mm × 12.50mm, both with identical seated height of 8.00mm maximum. Both components are tested at 1 kHz inductance frequency and carry Active product status.

Parameter Comparison

Engineering Selection Recommendations

Both the SCRH127-100 and CDRH127NP-100MC maintain Active product status with full ROHS3 and REACH compliance. The substitute part carries identical regulatory certifications and moisture sensitivity classification. The primary consideration is the operating temperature upper limit: the main part supports 125°C while the substitute supports 100°C. Selection should account for the specific thermal environment of the application. The substitute's slightly smaller footprint (12.00mm versus 12.50mm) may provide layout advantages in space-constrained designs while maintaining identical seated height. Both components are suitable for industrial applications requiring shielded inductance with stable DC resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can CDRH127NP-100MC replace SCRH127-100 in all applications?

A: Substitution is valid for applications operating at or below 100°C. Applications requiring the full -40°C to 125°C temperature range of the main part require the original SCRH127-100.

Q: Are the physical dimensions compatible for PCB layout?

A: Both components have identical seated height (8.00mm). The substitute is slightly smaller in footprint (12.00mm × 12.00mm versus 12.50mm × 12.50mm), which may require PCB layout verification but generally allows direct substitution with potential space savings.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both SCRH127-100 and CDRH127NP-100MC are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1, Unlimited).

Q: What is the difference in current handling between these parts?

A: The main part is rated for 5.67 A continuous current. The substitute is rated for 5.4 A continuous current. The substitute's saturation current matches the main part's saturation specification at 5.4 A. Applications requiring the full 5.67 A rating must use the original SCRH127-100.

Q: Are the DC resistance characteristics identical?

A: Yes. Both parts specify 21.6 mOhm maximum DC resistance, ensuring equivalent power dissipation and thermal performance in circuit operation.

Q: What packaging formats are available for each part?

A: SCRH127-100 is supplied in Tape & Reel (TR) format. CDRH127NP-100MC is supplied in Cut Tape (CT) and Digi-Reel format. Packaging selection depends on assembly process requirements and volume needs.
