Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDRH74-100MC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 10 µH (exact match required)
• Inductance tolerance: ±20% (exact match required)
• Shielding: Shielded (required for EMI performance)
• Mounting type: Surface Mount (required for PCB compatibility)
• Package footprint compatibility: Nonstandard 7.30mm x 7.30mm base dimension

Secondary Compatibility Criteria:

• Current rating: Substitute must equal or exceed 1.84 A
• DC resistance: Substitute must not exceed 49 mOhm Max (electrical performance)
• Operating temperature range: Substitute must cover or exceed -40°C ~ 100°C
• RoHS compliance: Active substitutes must meet ROHS3 compliance

All substitute parts listed meet the primary matching criteria. Secondary criteria variations are documented to enable informed selection based on specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Recommended Primary Substitute):

CDRH74NP-100MC-B is the direct equivalent from the same manufacturer (Sumida America Components Inc.). This part maintains identical electrical specifications (10 µH, 1.84 A, 49 mOhm Max DCR) and physical dimensions (7.30mm x 7.30mm x 4.50mm). The primary distinction is product status: CDRH74NP-100MC-B is active and ROHS3 compliant, whereas the original CDRH74-100MC is obsolete and RoHS non-compliant. Packaging is upgraded to Tape & Reel (TR) format with significantly higher inventory availability (6200 Pcs vs. 1730 Pcs).

Cross-Manufacturer Substitutes (Secondary Options):

P1167.103NLT (Pulse Electronics) provides enhanced current rating (2 A vs. 1.84 A) and extended operating temperature range (-40°C ~ 130°C vs. -40°C ~ 100°C). DC resistance is marginally higher at 50 mOhm Max. Physical dimensions are slightly larger (7.54mm x 7.54mm). This substitute is suitable for applications requiring higher thermal margin or increased current headroom.

B82472G6103M000 (EPCOS - TDK Electronics) offers comparable current rating (1.9 A) with slightly elevated DC resistance (53 mOhm Max). Operating temperature range extends to -55°C ~ 125°C. Physical footprint matches the original (7.30mm x 7.30mm). This substitute is appropriate for applications requiring extended low-temperature operation.

DR74-100-R (Eaton - Electronics Division) provides the highest current rating (2.41 A) with DC resistance of 48.9 mOhm, matching the original specification. Operating temperature range is -40°C ~ 125°C. Physical dimensions are marginally larger (7.60mm x 7.60mm) with reduced height (4.35mm vs. 4.50mm). This substitute is optimal for high-current applications with tight thermal constraints.

All substitute parts are ROHS3 compliant and maintain shielded construction with 10 µH inductance and ±20% tolerance.

Frequently Asked Questions (FAQ)

Q: Can CDRH74NP-100MC-B be used as a direct replacement for CDRH74-100MC?

A: Yes. CDRH74NP-100MC-B is the direct equivalent with identical electrical and mechanical specifications. The primary differences are product status (active vs. obsolete) and packaging format (Tape & Reel vs. nonstandard). Both parts are rated for 10 µH, 1.84 A, and 49 mOhm Max DCR with identical physical dimensions.

Q: What are the physical footprint differences among substitute parts?

A: CDRH74NP-100MC-B and B82472G6103M000 maintain the original 7.30mm x 7.30mm footprint. P1167.103NLT is slightly larger at 7.54mm x 7.54mm. DR74-100-R is 7.60mm x 7.60mm with reduced height (4.35mm vs. 4.50mm). All parts maintain 4.50mm maximum seated height except DR74-100-R. PCB layout verification is required for P1167.103NLT and DR74-100-R due to footprint variations.

Q: Which substitute offers the best thermal performance?

A: P1167.103NLT provides the widest operating temperature range (-40°C ~ 130°C) and highest current rating (2 A). B82472G6103M000 extends low-temperature operation to -55°C. DR74-100-R supports -40°C ~ 125°C with the highest current rating (2.41 A). Selection depends on specific thermal requirements.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts (CDRH74NP-100MC-B, P1167.103NLT, B82472G6103M000, and DR74-100-R) are ROHS3 compliant. The original CDRH74-100MC is RoHS non-compliant.

Q: What is the significance of DC resistance differences?

A: DC resistance affects power dissipation and thermal performance. The original CDRH74-100MC specifies 49 mOhm Max. P1167.103NLT is 50 mOhm Max (1 mOhm higher), B82472G6103M000 is 53 mOhm Max (4 mOhm higher), and DR74-100-R is 48.9 mOhm (0.1 mOhm lower). For applications with tight thermal budgets, DR74-100-R offers minimal resistance increase.

Q: Can substitutes with higher current ratings be used in place of the original?

A: Yes. Substitutes with equal or higher current ratings (P1167.103NLT at 2 A, B82472G6103M000 at 1.9 A, DR74-100-R at 2.41 A) are electrically compatible. Higher current ratings provide design margin and do not negatively impact circuit performance. Verify DC resistance and thermal characteristics for specific applications.

Q: What packaging format should be selected for production?

A: All substitute parts are available in Tape & Reel (TR) packaging, suitable for automated assembly. The original CDRH74-100MC used nonstandard packaging. TR format is standard for high-volume production and provides superior handling and storage characteristics.
