Engineering Selection Recommendations

Tier 1 - Direct Substitutes (Highest Compatibility):

The UP2B-1R5-R (Eaton) and B82476B1152M100 (EPCOS - TDK Electronics) provide the closest electrical match to the CDR95NP-1R5MC. Both maintain unshielded configuration, ferrite core construction, and current ratings within 15% of the original specification. UP2B-1R5-R offers superior current handling (8.3 A) and lowest DCR (8.1 mOhm), with active product status and RoHS compliance. B82476B1152M100 extends operating temperature range to -55°C to 150°C and includes AEC-Q200 automotive qualification.

Tier 2 - Functional Equivalents (Acceptable for Most Applications):

SDR1005-1R5ML (Bourns) and P0751.152NLT (Pulse Electronics) satisfy core electrical requirements with minor current rating reductions (6.5 A and 6.4 A respectively). Both maintain unshielded construction and ferrite cores. SDR1005-1R5ML provides documented Q factor (50 @ 3MHz) and self-resonant frequency (95 MHz). P0751.152NLT matches the original DCR specification at 12 mOhm maximum and extends temperature range to 130°C.

Tier 3 - High-Current Alternative:

SDR2207-1R5ML (Bourns) serves applications requiring enhanced current capacity (15 A continuous, 25 A saturation) with superior thermal performance (5 mOhm DCR). This part accommodates designs with higher power requirements while maintaining 1.5 µH inductance and unshielded configuration.

Shielded Alternative:

B82464G4152M000 (EPCOS - TDK Electronics) provides shielded construction for EMI-sensitive applications, with AEC-Q200 qualification and extended temperature range (-55°C to 150°C). Current rating reduction to 7 A and saturation current of 8.5 A require circuit verification.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and surface mount packaging. Product status is active for all alternatives, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can B82464G4152M000 replace CDR95NP-1R5MC in all applications?

A: B82464G4152M000 is electrically equivalent for inductance and core material but introduces shielding. Shielded construction reduces electromagnetic coupling to adjacent components, which may alter circuit behavior in sensitive layouts. Current rating is reduced to 7 A. Verify circuit performance before production implementation.

Q: What is the difference between shielded and unshielded inductors in this product line?

A: Unshielded inductors (CDR95NP-1R5MC, B82476B1152M100, P0751.152NLT, SDR1005-1R5ML, SDR2207-1R5ML, UP2B-1R5-R) exhibit higher electromagnetic field radiation and are suitable for isolated circuit sections. Shielded inductors (B82464G4152M000) contain magnetic fields within the component, reducing EMI but typically increasing DCR and cost.

Q: Is SDR2207-1R5ML suitable as a direct replacement?

A: SDR2207-1R5ML maintains 1.5 µH inductance and unshielded ferrite core construction but is physically larger (22.00mm × 15.00mm vs. 12.90mm × 9.40mm) with significantly higher current capacity (15 A vs. 8 A). Use only if PCB layout accommodates larger footprint and circuit design benefits from enhanced current handling.

Q: Which substitute offers the best thermal performance?

A: SDR2207-1R5ML provides the lowest DC resistance (5 mOhm maximum), resulting in minimal I²R losses and superior thermal performance. UP2B-1R5-R offers the next best thermal characteristics (8.1 mOhm DCR) with a more compact footprint.

Q: Are all substitutes RoHS3 compliant?

A: All listed substitute parts are RoHS3 compliant. B82464G4152M000 and B82476B1152M100 include REACH Unaffected status documentation. UP2B-1R5-R carries RoHS Compliant designation. Verify compliance documentation for specific procurement requirements.

Q: What is the impact of DCR variation on circuit performance?

A: DC resistance directly affects power dissipation (P = I²R) and thermal rise. CDR95NP-1R5MC specifies 8.2 mOhm maximum. Substitutes with higher DCR (9-12 mOhm) generate proportionally greater heat at rated current. Applications operating at continuous 8 A should prioritize substitutes with DCR ≤ 9 mOhm.

Q: Can I use P0751.152NLT if my circuit operates at 6.4 A maximum?

A: Yes. P0751.152NLT is rated for 6.4 A continuous current with 8 A saturation. If circuit design limits current to 6.4 A or below, this part provides full functional equivalence with extended temperature range (-40°C to 130°C) and matching DCR specification (12 mOhm maximum).

Q: What certifications should I verify for automotive applications?

A: B82464G4152M000 and B82476B1152M100 carry AEC-Q200 automotive qualification. Other substitutes lack explicit automotive certification. For automotive designs, prioritize AEC-Q200 qualified parts or conduct qualification testing per applicable standards.

Q: How do I determine if a substitute's saturation current is adequate?

A: Saturation current (Isat) defines the maximum current before inductance degrades significantly. CDR95NP-1R5MC specifies 12 A saturation. Substitutes with lower Isat (7.9-8.5 A) require circuit verification to ensure peak transient currents remain below saturation limits. SDR2207-1R5ML (25 A Isat) provides substantial margin for high-current transients.
