Substitute Part Grouping Explanation
Substitute parts for the CDRH127-150MC are classified into two categories based on electrical and mechanical compatibility:
Direct Substitutes maintain identical or equivalent electrical specifications and physical dimensions, allowing pin-for-pin replacement without circuit redesign. These parts share the same inductance value (15 µH), tolerance (±20%), shielding type (shielded), mounting configuration (surface mount), and package dimensions (12.00mm x 12.00mm footprint with 8.00mm maximum height).
Similar Substitutes provide functionally equivalent inductance performance within the same application envelope but may exhibit variations in current rating, DC resistance, core material, or operating temperature range. These parts are suitable for applications where the primary design requirement is 15 µH inductance at surface mount configuration, with tolerance for minor electrical parameter variations.
Substitution eligibility is determined by the following critical parameters:
- Inductance value: 15 µH (fixed requirement)
- Inductance tolerance: ±20% (fixed requirement)
- Shielding: Shielded (fixed requirement)
- Mounting type: Surface Mount (fixed requirement)
- Physical footprint: 12.00mm x 12.00mm nominal (allows ±0.5mm variation)
- Height: 8.00mm maximum seated height (fixed requirement)

Engineering Selection Recommendations
Primary Recommendation: CDRH127NP-150MC
The CDRH127NP-150MC is the direct equivalent replacement for the obsolete CDRH127-150MC. Both parts are manufactured by Sumida America Components Inc. and share identical electrical specifications (15 µH, ±20% tolerance, 4.5 A rating, 27 mOhm DCR) and physical dimensions (12.00mm x 12.00mm footprint, 8.00mm maximum height). The CDRH127NP-150MC is currently in active product status with ROHS3 compliance, making it the optimal choice for design continuity and supply chain stability. This part requires no circuit modifications and provides direct pin-for-pin compatibility.
Secondary Recommendations: P1172.153NLT and P1173.153NLT
The Pulse Electronics P1172.153NLT and P1173.153NLT are functionally equivalent alternatives with active product status and ROHS3 compliance. Both parts maintain 15 µH inductance with ±20% tolerance and shielded configuration. These parts feature slightly lower current ratings (4.1 A versus 4.5 A) and higher DC resistance (35.4 mOhm versus 27 mOhm), but operate across an extended temperature range (-40°C to 130°C versus -40°C to 100°C). Physical dimensions are marginally larger (12.24mm x 12.24mm versus 12.00mm x 12.00mm), requiring verification of PCB layout compatibility. These parts are suitable for applications where the lower current rating and higher DCR are acceptable.
Tertiary Recommendations: DR127-150-R, SLF12575T-150M4R7-H, SLF12575T-150M4R7-PF
The Eaton DR127-150-R provides superior electrical performance with higher current rating (5.03 A), lower DC resistance (24.7 mOhm), and higher saturation current (9.66 A). Physical dimensions are 12.50mm x 12.50mm, requiring PCB layout verification. The TDK SLF12575T-150M4R7-H and SLF12575T-150M4R7-PF offer low DC resistance (22.08 mOhm and 22.1 mOhm respectively) and are classified as "Not For New Designs," indicating these are legacy products suitable only for sustaining production of existing designs. Both TDK parts feature slightly reduced height (7.85mm versus 8.00mm) and larger footprints (12.50mm x 12.50mm).
Frequently Asked Questions (FAQ)
Q: Can CDRH127NP-150MC be used as a direct replacement for CDRH127-150MC?
A: Yes. The CDRH127NP-150MC is a direct equivalent with identical inductance (15 µH), tolerance (±20%), current rating (4.5 A), DC resistance (27 mOhm), shielding, and physical dimensions (12.00mm x 12.00mm x 8.00mm). The primary difference is product status (active versus obsolete) and RoHS compliance (ROHS3 compliant versus non-compliant). No circuit modifications are required.
Q: What are the key differences between the Sumida CDRH127NP-150MC and Pulse Electronics P1172.153NLT?
A: Both parts maintain 15 µH inductance and ±20% tolerance. The CDRH127NP-150MC provides 4.5 A current rating with 27 mOhm DCR, while the P1172.153NLT provides 4.1 A current rating with 35.4 mOhm DCR. The P1172.153NLT operates across a wider temperature range (-40°C to 130°C versus -40°C to 100°C) and has a slightly larger footprint (12.24mm x 12.24mm versus 12.00mm x 12.00mm). Selection depends on current and thermal requirements.
Q: Are the TDK SLF12575T series parts suitable for new designs?
A: No. Both SLF12575T-150M4R7-H and SLF12575T-150M4R7-PF are classified as "Not For New Designs," indicating these are legacy products. They are suitable only for sustaining production of existing designs that already incorporate these parts. For new designs, use CDRH127NP-150MC or active alternatives such as DR127-150-R or Pulse Electronics parts.
Q: What is the impact of DC resistance variation among substitute parts?
A: DC resistance directly affects power dissipation and thermal performance. The CDRH127-150MC and CDRH127NP-150MC specify 27 mOhm maximum DCR. The Eaton DR127-150-R provides lower DCR (24.7 mOhm), reducing power loss. The Pulse Electronics parts specify higher DCR (35.4 mOhm), increasing power dissipation.
