SCRH127-820 Equivalent & Substitute Parts

Part Overview

The SCRH127-820 is a 82 µH shielded surface mount inductor manufactured by Signal Transformer, rated for 2 A continuous current with a maximum DC resistance of 160mOhm. This component is designed for applications requiring fixed inductance in compact form factors with electromagnetic shielding. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified to provide design flexibility when the primary part is unavailable or when alternative packaging formats are preferred, while maintaining electrical and mechanical compatibility within specified tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SCRH127-820 is determined by the following critical parameters:

• Inductance Value: 82 µH with ±20% tolerance
• DC Resistance: 160mOhm maximum
• Current Rating: Minimum 1.95 A (saturation current of primary part)
• Shielding: Shielded construction required
• Mounting: Surface mount configuration
• Temperature Range: Overlap within operational limits
• Compliance: ROHS3 compliance maintained

The CDRH127NP-820MC from Sumida America Components Inc. meets these substitution criteria. Both parts share identical inductance specifications, DC resistance ratings, shielding characteristics, and surface mount configuration. The substitute part operates within a -40°C to 100°C range, which encompasses the primary operating window of the main part.

Parameter Comparison

Engineering Selection Recommendations

Both the SCRH127-820 and CDRH127NP-820MC are active production components with ROHS3 compliance and identical moisture sensitivity ratings. Selection between these parts should be based on:

Availability and Packaging: The CDRH127NP-820MC offers higher inventory availability (10,266 pcs vs. 926 pcs) and is available in Cut Tape and Digi-Reel® formats, providing flexibility for different procurement workflows.

Current Margin: The SCRH127-820 provides a 2 A rating versus the substitute's 1.95 A rating. Applications operating near maximum current specifications should verify that the 1.95 A rating of the substitute part provides adequate margin for the intended circuit.

Temperature Operating Range: The SCRH127-820 extends to 125°C maximum, while the CDRH127NP-820MC is rated to 100°C. Designs requiring operation above 100°C must use the primary part.

Physical Footprint: The CDRH127NP-820MC has a slightly smaller footprint (12.00mm x 12.00mm vs. 12.50mm x 12.50mm) while maintaining identical height. Both are compatible with standard nonstandard package layouts.

Frequently Asked Questions (FAQ)

Q: Can CDRH127NP-820MC be used as a direct replacement for SCRH127-820?

A: Yes, for applications operating at or below 1.95 A and 100°C maximum temperature. The inductance value, DC resistance, shielding, and mounting type are identical. Verify current and temperature requirements before substitution.

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

A: The SCRH127-820 is rated for 2 A continuous current, while the CDRH127NP-820MC is rated for 1.95 A. The saturation current of the primary part is 1.95 A, matching the full rating of the substitute. Applications must not exceed 1.95 A with the substitute part.

Q: Are the physical dimensions compatible?

A: Both parts have identical height (8.00mm). The CDRH127NP-820MC has a slightly smaller footprint (12.00mm x 12.00mm vs. 12.50mm x 12.50mm). This smaller footprint is compatible with layouts designed for the larger primary part, but verify PCB land pattern compatibility for the substitute.

Q: What packaging formats are available?

A: The SCRH127-820 is supplied in Tape & Reel (TR) format. The CDRH127NP-820MC is available in Cut Tape (CT) and Digi-Reel® formats. Select based on assembly equipment and procurement requirements.

Q: Are both parts RoHS compliant?

A: Yes, both the SCRH127-820 and CDRH127NP-820MC are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity rating).

Q: What is the maximum operating temperature for each part?

A: The SCRH127-820 operates from -40°C to 125°C. The CDRH127NP-820MC operates from -40°C to 100°C. Applications requiring operation above 100°C must use the primary part.
