CDR95NP-151MC Equivalent & Substitute Parts

Part Overview

The CDR95NP-151MC is a 150 µH unshielded drum core wirewound inductor manufactured by Sumida America Components Inc., rated for 900 mA continuous current with a maximum DC resistance of 454mOhm. This surface mount component operates across the temperature range of -40°C to 100°C and is RoHS3 compliant with MSL 1 rating.

The CDR95NP-151MC is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Active alternative inductors with matching or superior electrical characteristics are available from multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR95NP-151MC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 150 µH (fixed requirement)
• Inductance tolerance: ±20% or tighter
• Mounting type: Surface Mount (nonstandard package)
• Core material: Ferrite drum core construction
• Shielding configuration: Unshielded (primary requirement)
• RoHS3 compliance and MSL 1 rating

Secondary Compatibility Criteria:

• Current rating: Minimum 900 mA (equal or greater acceptable)
• DC resistance: Maximum 454mOhm or lower preferred
• Operating temperature: Minimum -40°C to 100°C range coverage
• Saturation current: Minimum 1.1 A

Substitute parts are classified into two categories:

Direct Substitutes meet all primary and secondary criteria with no design modifications required.

Similar Substitutes meet primary criteria but may have variations in secondary parameters (such as higher current ratings, lower DCR, or extended temperature ranges) that provide enhanced performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

P0752.154NLT (Pulse Electronics) is classified as a direct substitute. This part maintains 150 µH inductance with ±20% tolerance matching the original specification. The 1 A current rating exceeds the 900 mA requirement, and the extended operating temperature range (-40°C to 130°C) provides superior thermal coverage. Active product status ensures ongoing availability. RoHS3 compliance and MSL 1 rating align with the original component. The 570mOhm maximum DCR is slightly elevated compared to the original 454mOhm specification but remains within acceptable engineering margins for most applications.

SDR1005-151KL (Bourns Inc.) is classified as a direct substitute. This inductor provides tighter inductance tolerance (±10% versus ±20%), which may improve circuit performance in precision applications. The 800 mA current rating is slightly below the original 900 mA specification; this part is suitable for applications where the actual operating current does not exceed 800 mA. The 590mOhm maximum DCR is higher than the original. Active product status and full RoHS3/MSL 1 compliance are confirmed. Operating temperature range extends to 125°C.

ASPI-104S-151M-T (Abracon LLC) is classified as a similar substitute. This part differs from the original in that it features shielded construction rather than unshielded. The 850 mA current rating approaches the 900 mA original specification. The 506mOhm maximum DCR is closer to the original value. Active product status and RoHS3/MSL 1 compliance are confirmed. The operating temperature range is limited to -40°C to 85°C, which does not fully cover the original -40°C to 100°C specification. This part is suitable only for applications where the upper temperature limit does not exceed 85°C.

SDR1305-151K (Bourns Inc.) is classified as a similar substitute. This inductor offers superior electrical characteristics with a 1.2 A current rating and a notably lower 380mOhm maximum DCR, representing a 16% improvement over the original specification. Inductance tolerance is tighter at ±10%. Active product status and full RoHS3/MSL 1 compliance are confirmed. Operating temperature range extends to 125°C. This part is suitable for applications requiring enhanced current handling capacity and reduced resistive losses.

Frequently Asked Questions (FAQ)

Q: Can P0752.154NLT directly replace CDR95NP-151MC without circuit modifications?

A: Yes. P0752.154NLT maintains the 150 µH inductance value and ±20% tolerance specification. The higher current rating (1 A versus 900 mA) and extended temperature range provide design margin. The 570mOhm DCR is slightly elevated but compatible with most circuit designs. No modifications are required.

Q: Why is SDR1005-151KL rated for only 800 mA when the original is 900 mA?

A: SDR1005-151KL is suitable for applications where the actual operating current does not exceed 800 mA. If your circuit requires 900 mA continuous current, this part is not appropriate. Verify actual circuit current requirements before selection.

Q: What is the significance of the shielded construction in ASPI-104S-151M-T?

A: ASPI-104S-151M-T features shielded construction, which reduces electromagnetic interference emission and susceptibility compared to the unshielded original. This is beneficial in noise-sensitive applications but may not be necessary if the original unshielded design was adequate. Shielding also affects the physical footprint and thermal characteristics.

Q: Does ASPI-104S-151M-T meet the full operating temperature range of the original?

A: No. ASPI-104S-151M-T operates from -40°C to 85°C, which does not cover the original -40°C to 100°C range. This part is suitable only for applications where the maximum operating temperature does not exceed 85°C.

Q: Which substitute offers the best electrical performance?

A: SDR1305-151K provides the lowest DC resistance (380mOhm maximum) and highest current rating (1.2 A), representing enhanced performance characteristics. However, "best" depends on specific application requirements. Verify that the larger physical dimensions (0.500" L x 0.500" W) fit your PCB layout.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are RoHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original component's environmental compliance profile.

Q: What is the difference between "Direct Substitute" and "Similar Substitute" classifications?

A: Direct substitutes meet all primary and secondary electrical specifications with no design modifications required. Similar substitutes meet primary specifications but have variations in secondary parameters (such as temperature range or shielding configuration) that may require application-specific evaluation.

Q: Can I use SDR1305-151K in a space-constrained application?

A: SDR1305-151K has larger physical dimensions (0.500" L x 0.500" W, 5.10mm height) compared to the original CDR95NP-151MC (0.508" L x 0.370" W, 5.20mm height). Verify PCB layout compatibility before selection. The increased footprint may not fit existing designs without modification.
