CDRH127-680MC Equivalent & Substitute Parts

Part Overview

The CDRH127-680MC is a 68 µH shielded surface mount inductor manufactured by Sumida America Components Inc., rated for 2.1 A continuous current with a maximum DC resistance of 140 mOhm. This component is classified as obsolete, necessitating identification of equivalent and substitute parts for ongoing design support and procurement continuity. The part operates across the temperature range of -40°C to 100°C and is mounted in a nonstandard 12.00mm × 12.00mm package with 8.00mm seated height.

Due to its obsolete status, alternative components with matching or superior electrical and mechanical characteristics are required for new production runs and design revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CDRH127-680MC are classified into two categories based on electrical and mechanical compatibility:

Direct Substitutes maintain identical electrical specifications (68 µH inductance, ±20% tolerance, 2.1 A current rating, 140 mOhm maximum DCR) and mechanical form factor (12.00mm × 12.00mm × 8.00mm). These parts differ primarily in product status, packaging format, and regulatory compliance.

Similar Substitutes maintain the core electrical specifications (68 µH inductance, ±20% tolerance, 2.1 A minimum current rating) but exhibit variations in DC resistance, package dimensions, operating temperature range, or core construction. These parts are suitable when the application tolerates minor parameter deviations within the specified ranges.

The substitution logic is based on the following critical parameters:

• Inductance value and tolerance
• Current rating (minimum 2.1 A)
• DC resistance (≤140 mOhm preferred)
• Shielding requirement
• Surface mount package compatibility
• Operating temperature range overlap

Engineering Selection Recommendations

Primary Recommendation: CDRH127NP-680MC

The CDRH127NP-680MC is the direct functional equivalent of the obsolete CDRH127-680MC. Both parts are manufactured by Sumida America Components Inc. within the CDRH127 series and maintain identical electrical specifications and mechanical dimensions. The primary distinction is product status: CDRH127NP-680MC is active and ROHS3 compliant, whereas the original part is obsolete and non-compliant. This part is available in Tape & Reel packaging with 1920 units in stock, providing immediate procurement viability.

Secondary Recommendations: P1173.683NLT and P1172.683NLT

Both Pulse Electronics parts (P1173.683NLT and P1172.683NLT) maintain the 68 µH inductance, ±20% tolerance, and 2.1 A current rating. These wirewound inductors feature improved DC resistance (135 mOhm maximum, compared to 140 mOhm), extended operating temperature range (-40°C to 130°C), and ROHS3 compliance. Package dimensions are marginally larger (12.24mm × 12.24mm versus 12.00mm × 12.00mm), which may require PCB layout verification. Both parts are active with substantial inventory availability (898 and 1091 units respectively).

Alternative Recommendation: DR127-680-R

The Eaton DR127-680-R offers superior electrical performance with 105 mOhm maximum DCR and 2.44 A current rating, exceeding the original specification. The drum core, wirewound construction with ferrite core provides enhanced performance characteristics. Package dimensions are 12.50mm × 12.50mm, requiring PCB footprint validation. Operating temperature range extends to 125°C. This part is active, ROHS3 compliant, and available in Cut Tape & Digi-Reel packaging with 1553 units in stock.

Frequently Asked Questions (FAQ)

Q: Can CDRH127NP-680MC be used as a direct replacement for CDRH127-680MC?

A: Yes. CDRH127NP-680MC is electrically and mechanically identical to CDRH127-680MC. Both maintain 68 µH inductance, ±20% tolerance, 2.1 A current rating, 140 mOhm maximum DCR, and identical package dimensions (12.00mm × 12.00mm × 8.00mm). The primary difference is product status and regulatory compliance. CDRH127NP-680MC is active and ROHS3 compliant.

Q: What are the implications of using Pulse Electronics parts (P1173.683NLT or P1172.683NLT) instead of the Sumida part?

A: Pulse Electronics parts maintain the same inductance value, tolerance, and current rating. DC resistance is improved at 135 mOhm maximum. Package dimensions are slightly larger (12.24mm × 12.24mm), requiring PCB layout verification to confirm clearance. Operating temperature range is extended to 130°C. Both parts are wirewound construction and ROHS3 compliant.

Q: Is the Eaton DR127-680-R suitable for applications requiring the original CDRH127-680MC specifications?

A: The Eaton DR127-680-R maintains the 68 µH inductance and ±20% tolerance. Current rating is higher at 2.44 A, and DC resistance is lower at 105 mOhm, both representing performance improvements. Package dimensions are 12.50mm × 12.50mm, requiring PCB footprint validation. Operating temperature range extends to 125°C. This part is suitable when the application tolerates the dimensional variation and benefits from improved electrical performance.

Q: What packaging formats are available for these substitute parts?

A: CDRH127NP-680MC is supplied in Tape & Reel (TR) format. P1173.683NLT and P1172.683NLT are supplied in Tape & Reel (TR) format. DR127-680-R is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts RoHS compliant?

A: CDRH127NP-680MC, P1173.683NLT, P1172.683NLT, and DR127-680-R are all ROHS3 compliant. The original CDRH127-680MC is RoHS non-compliant. For applications requiring RoHS compliance, any of the substitute parts are suitable.

Q: What is the significance of the inductance test frequency difference between parts?

A: The original CDRH127-680MC specifies inductance measurement at 1 kHz. Pulse Electronics parts (P1173.683NLT and P1172.683NLT) and the Eaton DR127-680-R specify measurement at 100 kHz. Inductance values may vary slightly across frequency ranges due to core material properties. The specified 68 µH value with ±20% tolerance encompasses these measurement conditions.
