Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR74NP-150NC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 15 µH (exact match required)
• Shielding: Shielded configuration
• Mounting type: Surface Mount
• RoHS3 compliance

Secondary Compatibility Factors:

• Current rating must equal or exceed 1.34 A
• DC resistance must not exceed 90 mOhm
• Physical dimensions must accommodate board layout constraints
• Nonstandard package compatibility with existing footprints

Two substitute parts meet these criteria and are listed in the original part's substitution field.

Parameter Comparison

Engineering Selection Recommendations

CDRH74NP-150MC-B (Sumida America Components Inc.)

This substitute is the closest functional equivalent to the CDR74NP-150NC. Both components are manufactured by Sumida and share the same 15 µH inductance value with identical shielded surface mount configuration. The CDRH74NP-150MC-B provides improved specifications: higher current rating (1.47 A vs. 1.34 A), lower DC resistance (81 mOhm vs. 90 mOhm), and tighter tolerance (±20% vs. -15%, +25%). The part is active in production with full RoHS3 compliance and unlimited MSL rating. Physical dimensions are slightly smaller (7.30mm x 7.30mm vs. 7.70mm x 7.10mm) with reduced height (4.50mm vs. 4.85mm), requiring verification of PCB footprint compatibility. Operating temperature range is specified at -40°C to 100°C.

SRR7045-150M (Bourns Inc.)

This substitute offers superior electrical performance with the same 15 µH inductance. The SRR7045-150M provides significantly higher current rating (2.2 A vs. 1.34 A), lower DC resistance (62 mOhm vs. 90 mOhm), and extended operating temperature range (-40°C to 125°C). The part features a drum core wirewound construction with ferrite material, Q factor of 31 at 2.52 MHz, and self-resonant frequency of 24 MHz. Physical dimensions are the smallest of the three options (7.00mm x 7.00mm) with height of 4.80mm. This part is active in production with full RoHS3 compliance and unlimited MSL rating. Footprint compatibility must be verified due to dimensional differences.

Both substitute parts are active products with established supply chains, making them suitable for long-term design continuity beyond the obsolete CDR74NP-150NC.

Frequently Asked Questions (FAQ)

Q: Can CDRH74NP-150MC-B directly replace CDR74NP-150NC without circuit modification?

A: The CDRH74NP-150MC-B meets all critical electrical parameters (15 µH inductance, shielded configuration, surface mount) with improved current rating and lower DC resistance. However, physical dimensions differ slightly (7.30mm x 7.30mm vs. 7.70mm x 7.10mm). PCB footprint compatibility must be verified before implementation. No circuit modification is required if footprint accommodation is confirmed.

Q: What are the key differences between CDRH74NP-150MC-B and SRR7045-150M?

A: Both parts maintain the 15 µH inductance specification. CDRH74NP-150MC-B is a Sumida product with 1.47 A rating and 81 mOhm DCR. SRR7045-150M is a Bourns drum core wirewound inductor with higher current rating (2.2 A), lower DCR (62 mOhm), and extended temperature range (-40°C to 125°C vs. -40°C to 100°C). SRR7045-150M has the smallest footprint (7.00mm x 7.00mm). Selection depends on thermal requirements, current headroom needs, and available board space.

Q: Are all three parts RoHS3 compliant?

A: Yes. CDR74NP-150NC, CDRH74NP-150MC-B, and SRR7045-150M are all RoHS3 compliant with MSL 1 (unlimited moisture sensitivity rating).

Q: What is the impact of different DC resistance values?

A: The CDR74NP-150NC has 90 mOhm maximum DCR. CDRH74NP-150MC-B reduces this to 81 mOhm, and SRR7045-150M further reduces it to 62 mOhm. Lower DCR results in reduced power dissipation and heat generation at the same current levels. For applications with tight thermal budgets or high continuous current operation, the lower DCR of SRR7045-150M provides performance advantage.

Q: Can SRR7045-150M be used in applications requiring the exact CDR74NP-150NC footprint?

A: SRR7045-150M has different physical dimensions (7.00mm x 7.00mm vs. 7.70mm x 7.10mm). While the height is comparable (4.80mm vs. 4.85mm), the smaller footprint requires PCB layout verification. If the original design has tight spacing constraints, footprint compatibility must be confirmed before substitution.

Q: What is the significance of the inductance tolerance differences?

A: CDR74NP-150NC has -15%, +25% tolerance, while both substitutes specify ±20% tolerance. The tighter tolerance of the substitutes provides more predictable inductance values across production batches, beneficial for applications with strict frequency or impedance requirements.
