Substitute Part Grouping Explanation

Substitution eligibility for the CDR74BNP-150MC is determined by the following critical parameters:

Primary Electrical Compatibility Criteria:

Inductance value: 15 µH (exact match required)
Inductance tolerance: ±20% (must be equal or tighter)
Current rating: minimum 1.39 A (equal or higher acceptable)
DC resistance: 80 mOhm or lower (lower values acceptable)
Shielding type: Shielded (must match)
Core material: Ferrite (must match)

Mechanical & Environmental Criteria:

Mounting type: Surface Mount (must match)
RoHS compliance: ROHS3 Compliant (must match)
Moisture sensitivity: MSL 1 (must match or better)

The substitute part CDRH74NP-150MC-B meets all primary electrical compatibility criteria with improved current rating (1.47 A vs. 1.39 A) and comparable DC resistance (81 mOhm vs. 80 mOhm). The substitute maintains ferrite core shielded construction and surface mount configuration. The substitute part is classified as active product status, ensuring ongoing availability and supply chain support.

Engineering Selection Recommendations

The CDRH74NP-150MC-B is a qualified substitute for the obsolete CDR74BNP-150MC based on the following engineering factors:

Electrical Performance: Both components maintain identical inductance (15 µH) and tolerance (±20%). The substitute provides higher current rating (1.47 A vs. 1.39 A), offering improved thermal margin in current-limited applications. DC resistance values are equivalent (81 mOhm vs. 80 mOhm), resulting in negligible performance difference in power dissipation calculations.

Environmental & Compliance: The substitute operates across a wider temperature range (-40°C ~ 100°C vs. -25°C ~ 80°C), providing extended operational capability in extreme temperature environments. Both components maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and moisture handling compatibility.

Supply Chain & Availability: The substitute part is classified as active product status with 8142 units in stock, compared to the obsolete main part with 1084 units. Active status ensures long-term availability and supply continuity for production and design support.

Physical Dimensions: The substitute exhibits slightly smaller footprint (7.30mm x 7.30mm vs. 7.80mm x 7.00mm) and lower profile (4.50mm vs. 4.90mm), providing potential PCB layout optimization benefits.

Frequently Asked Questions (FAQ)

Q: Can CDRH74NP-150MC-B directly replace CDR74BNP-150MC in existing designs?

A: Yes. Both components share identical inductance (15 µH), tolerance (±20%), shielding type (shielded), core material (ferrite), and mounting configuration (surface mount). The substitute provides equal or superior electrical performance with higher current rating and equivalent DC resistance.

Q: What are the physical dimension differences between these parts?

A: CDR74BNP-150MC measures 7.80mm L x 7.00mm W x 4.90mm H (seated). CDRH74NP-150MC-B measures 7.30mm L x 7.30mm W x 4.50mm H (seated). The substitute is slightly more compact, requiring verification of PCB layout clearances in space-constrained applications.

Q: Are there packaging differences between the main part and substitute?

A: CDR74BNP-150MC is supplied in nonstandard packaging. CDRH74NP-150MC-B is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and may require adjustment to component handling procedures if transitioning from nonstandard packaging.

Q: What is the temperature operating range difference?

A: CDR74BNP-150MC operates from -25°C to 80°C. CDRH74NP-150MC-B operates from -40°C to 100°C. The substitute provides extended low-temperature capability (-40°C vs. -25°C) and extended high-temperature capability (100°C vs. 80°C), suitable for applications requiring broader thermal performance.

Q: Are both parts RoHS compliant?

A: Yes. Both CDR74BNP-150MC and CDRH74NP-150MC-B are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level), meeting regulatory requirements for electronic component procurement and assembly.

Q: What is the current rating difference and does it affect circuit design?

A: CDR74BNP-150MC is rated for 1.39 A maximum current. CDRH74NP-150MC-B is rated for 1.47 A maximum current. The 0.08 A increase provides additional thermal margin. For circuits operating at or near the 1.39 A limit, the substitute offers improved reliability and reduced thermal stress.
