Substitute Part Grouping Explanation

Substitute parts for the CDRR157NP-150MC are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 15 µH (matching specification)
• Inductance tolerance: ±20% (matching specification)
• Current rating: minimum 3.6 A (within acceptable operating range)
• DC resistance: maximum 39 mOhm (within acceptable range for equivalent performance)
• Core material: Ferrite (matching specification)
• Shielding: Shielded (matching specification)
• Mounting type: Surface Mount (matching specification)
• RoHS compliance: ROHS3 Compliant (matching specification)
• Moisture sensitivity: MSL 1 (matching specification)

The SRR1806-150M from Bourns Inc. meets all primary substitution criteria. Physical dimensions remain within acceptable tolerance for board-level compatibility, and the component maintains equivalent electrical performance within the specified parameter ranges.

Engineering Selection Recommendations

CDRR157NP-150MC (Primary Component)

The CDRR157NP-150MC maintains Active product status with established supply chain availability (862 pcs in stock). This component is the preferred selection when available, as it represents the original design specification. RoHS3 compliance and MSL 1 rating confirm suitability for standard manufacturing and storage conditions.

SRR1806-150M (Qualified Substitute)

The SRR1806-150M from Bourns Inc. is a qualified substitute meeting all electrical and mechanical requirements. This component demonstrates superior saturation current performance (7.2 A versus 5 A) and extended operating temperature range (-40 to 125°C versus -40 to 100°C). RoHS3 compliance and MSL 1 rating match the primary component. Physical dimensions remain compatible with board-level placement. Higher inventory availability (1432 pcs in stock) supports supply chain continuity. Selection of this substitute is appropriate when primary component availability is constrained or when the extended performance envelope provides design margin benefits.

Frequently Asked Questions (FAQ)

Q: Can the SRR1806-150M directly replace the CDRR157NP-150MC in existing designs?

A: Yes. Both components share identical inductance values (15 µH), inductance tolerance (±20%), core material (Ferrite), shielding (Shielded), and mounting type (Surface Mount). Physical dimensions are compatible within standard PCB layout tolerances. Both components maintain RoHS3 compliance and MSL 1 rating.

Q: What are the differences in current handling between these components?

A: The CDRR157NP-150MC is rated for 3.8 A continuous current with 5 A saturation current. The SRR1806-150M is rated for 3.6 A continuous current with 7.2 A saturation current. For applications operating below 3.6 A, both components are functionally equivalent. For applications requiring continuous current between 3.6 A and 3.8 A, the CDRR157NP-150MC is the specified component.

Q: How do the DC resistance values compare?

A: The CDRR157NP-150MC specifies 37.5 mOhm maximum DC resistance. The SRR1806-150M specifies 39 mOhm DC resistance. This 1.5 mOhm difference represents approximately 4% variation and is within acceptable tolerance for equivalent circuit performance in most applications.

Q: Are there temperature range considerations for substitution?

A: The CDRR157NP-150MC operates from -40°C to 100°C. The SRR1806-150M operates from -40°C to 125°C. For applications operating within the -40°C to 100°C range, both components are equivalent. For applications requiring operation above 100°C, only the SRR1806-150M is suitable.

Q: Do both components meet the same compliance standards?

A: Yes. Both the CDRR157NP-150MC and SRR1806-150M are RoHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating. Both components are classified under ECCN EAR99 and HTSUS 8504.50.4000.

Q: What is the physical footprint difference?

A: The CDRR157NP-150MC measures 18.50 mm L × 15.00 mm W × 7.00 mm H (seated). The SRR1806-150M measures 18.30 mm L × 14.00 mm W × 7.10 mm H (seated). Dimensional variation is less than 1.5% across all axes and is compatible with standard PCB layout practices.
