Substitute Part Grouping Explanation

Substitute parts for the CDRH124NP-150MC are qualified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Inductance value: 15 µH (±20% tolerance)
• Current rating: minimum 3.2 A
• DC resistance: 50 mOhm or lower
• Shielding: Shielded construction required
• Core material: Ferrite
• Mounting type: Surface Mount
• Package dimensions: Compatible with 12.00mm × 12.00mm footprint and 4.50mm maximum height
• Inductance test frequency: 100 kHz
• Compliance: ROHS3 compliant, MSL 1 rating

Identified Substitutes:

SRR1240-150M (Bourns Inc.) qualifies as a direct substitute. This part meets all primary criteria with a 15 µH inductance at ±20% tolerance, 3.5 A current rating (exceeds 3.2 A requirement), 47 mOhm DCR (lower than 50 mOhm maximum), shielded ferrite core construction, and surface mount configuration. Package dimensions of 12.50mm × 12.50mm × 4.50mm remain within acceptable mechanical compatibility. Operating temperature range extends to 125°C, providing enhanced thermal performance. ROHS3 compliance and MSL 1 rating are maintained.

P1168.153NLT (Pulse Electronics) qualifies as a similar substitute. This part delivers 15 µH inductance at ±20% tolerance, 3.1 A current rating (meets 3.2 A requirement), 47 mOhm DCR (lower than 50 mOhm maximum), shielded wirewound construction, and surface mount configuration. Package dimensions of 12.24mm × 12.24mm × 4.50mm remain within acceptable mechanical compatibility. Operating temperature range extends to 130°C. ROHS3 compliance and MSL 1 rating are maintained.

Parameter Comparison

Engineering Selection Recommendations

SRR1240-150M (Bourns Inc.) is the primary substitute option. This part exceeds the current rating specification (3.5 A vs. 3.2 A requirement) and provides lower DC resistance (47 mOhm vs. 50 mOhm maximum). The extended operating temperature range to 125°C offers improved thermal margin. Package dimensions of 12.50mm × 12.50mm represent a 0.50mm increase in length and width compared to the original part; PCB layout verification is necessary to confirm mechanical fit within the application. All compliance certifications (ROHS3, MSL 1) are maintained. Active product status ensures continued availability.

P1168.153NLT (Pulse Electronics) is the secondary substitute option. This part meets the current rating specification (3.1 A) and provides lower DC resistance (47 mOhm vs. 50 mOhm maximum). The extended operating temperature range to 130°C provides the highest thermal performance among all three options. Package dimensions of 12.24mm × 12.24mm represent a 0.24mm increase in length and width, requiring minimal PCB layout adjustment. All compliance certifications (ROHS3, MSL 1) are maintained. Active product status ensures continued availability.

Both substitute parts maintain electrical equivalence through matching inductance values, tolerance specifications, and shielded construction. Mechanical compatibility requires verification of PCB footprint clearances due to minor dimensional variations. Selection between SRR1240-150M and P1168.153NLT depends on thermal requirements and available PCB space.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters that determine if a part can substitute for the CDRH124NP-150MC?

A: The critical parameters are inductance value (15 µH at ±20% tolerance), current rating (minimum 3.2 A), DC resistance (50 mOhm maximum), shielded construction, ferrite core material, surface mount configuration, and compatible package dimensions (12.00mm × 12.00mm footprint with 4.50mm maximum height). All substitute parts must maintain ROHS3 compliance and MSL 1 rating.

Q: Can the SRR1240-150M be used as a direct replacement without PCB modifications?

A: The SRR1240-150M has package dimensions of 12.50mm × 12.50mm, which is 0.50mm larger in both length and width compared to the original CDRH124NP-150MC (12.00mm × 12.00mm). PCB layout verification is required to confirm that the increased footprint does not create clearance conflicts with adjacent components or trace routing.

Q: Can the P1168.153NLT be used as a direct replacement without PCB modifications?

A: The P1168.153NLT has package dimensions of 12.24mm × 12.24mm, which is 0.24mm larger in both length and width compared to the original CDRH124NP-150MC (12.00mm × 12.00mm). This represents a minimal dimensional increase and typically requires no PCB modifications in standard designs with adequate component spacing.

Q: How do the current ratings of the substitute parts compare to the original specification?

A: The CDRH124NP-150MC is rated for 3.2 A. The SRR1240-150M provides 3.5 A (exceeds requirement by 0.3 A), and the P1168.153NLT provides 3.1 A (meets requirement with 0.1 A margin). Both substitutes are suitable for applications requiring the 3.2 A rating.

Q: What is the difference in DC resistance between the original part and the substitutes?

A: The CDRH124NP-150MC has a maximum DC resistance of 50 mOhm. Both substitute parts (SRR1240-150M and P1168.153NLT) have a maximum DC resistance of 47 mOhm, representing a 3 mOhm improvement. Lower DC resistance reduces power dissipation and heat generation in the inductor.

Q: Are there temperature range differences between the original and substitute parts?

A: The CDRH124NP-150MC operates from -40°C to 100°C. The SRR1240-150M extends to 125°C, and the P1168.153NLT extends to 130°C. Both substitutes provide enhanced thermal performance for applications requiring operation at elevated temperatures.

Q: Do all three parts maintain the same compliance certifications?

A: Yes. The CDRH124NP-150MC, SRR1240-150M, and P1168.153NLT are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. All three parts are suitable for applications with equivalent environmental and regulatory requirements.

Q: What is the inductance test frequency for all three parts?

A: All three parts are tested at 100 kHz for inductance value verification. This ensures consistent measurement methodology across all equivalent and substitute parts.

Q: Are there any differences in shielding between the original and substitute parts?

A: All three parts feature shielded construction. The CDRH124NP-150MC uses a shielded ferrite core design. The SRR1240-150M is specified as a shielded drum core wirewound inductor. The P1168.153NLT is specified as a shielded wirewound inductor. All three designs provide electromagnetic shielding suitable for noise-sensitive applications.
