Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CDR95NP-150MC is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 15 µH (exact match required)
• Tolerance: ±20% (standard specification)
• Shielding configuration: Unshielded (electrical characteristic)
• Mounting type: Surface Mount (mechanical requirement)
• RoHS3 compliance (regulatory requirement)

Secondary Compatibility Factors:

• Current rating: Minimum 3 A continuous
• DC resistance: Maximum 46.8 mOhm preferred; up to 60 mOhm acceptable with thermal analysis
• Saturation current: Minimum 3 A
• Operating temperature: Minimum -40°C to 100°C overlap required
• Package dimensions: Nonstandard form factor with height ≤ 5.5 mm

All substitute parts listed maintain the core electrical specifications (15 µH inductance, ±20% tolerance, unshielded configuration) and surface mount packaging. Variations in current rating, DC resistance, and temperature range are noted for application-specific selection.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Highest Compatibility):

P0751.153NLT (Pulse Electronics) and SDR1305-150M (Bourns Inc.) are the primary direct substitutes. Both maintain exact inductance (15 µH), identical tolerance (±20%), and unshielded configuration. P0751.153NLT offers extended temperature range (-40°C to 130°C) and active product status. SDR1305-150M provides superior current rating (3.3 A) and lower DC resistance (46 mOhm), with active status and extended temperature range (-40°C to 125°C). Both are RoHS3 compliant with MSL 1 rating.

Secondary Substitutes (Application-Dependent):

SDR1005-150ML (Bourns Inc.) maintains core specifications but operates at reduced continuous current (2.5 A) with elevated DC resistance (60 mOhm). This substitute is suitable only for applications where the 3 A rating is not critical. Active product status and RoHS3 compliance are confirmed.

UP2UC-150-R (Eaton - Electronics Division) provides 3.1 A current rating and 46 mOhm DC resistance, matching the main part's electrical performance. However, the operating temperature range (-25°C to 85°C) is narrower than the original specification, limiting use in applications requiring full -40°C operation. RoHS compliance is confirmed; active product status applies.

Compliance Considerations:

All substitute parts maintain RoHS3 compliance and MSL 1 rating, ensuring regulatory alignment with the original CDR95NP-150MC. Moisture sensitivity is not a limiting factor for any substitute.

Frequently Asked Questions (FAQ)

Q: Can P0751.153NLT replace CDR95NP-150MC in all applications?

A: P0751.153NLT is electrically compatible, matching the 15 µH inductance, ±20% tolerance, and 3 A current rating. The extended temperature range (-40°C to 130°C) provides additional operational margin. Physical dimensions are nearly identical (0.510" L × 0.370" W vs. 0.508" L × 0.370" W), with height difference of 0.010" (5.46 mm vs. 5.20 mm). Verify PCB layout clearance before implementation.

Q: What is the difference between SDR1305-150M and SDR1005-150ML?

A: Both are Bourns drum core wirewound inductors with 15 µH inductance. SDR1305-150M offers higher current rating (3.3 A vs. 2.5 A) and lower DC resistance (46 mOhm vs. 60 mOhm), making it suitable for higher-power applications. SDR1005-150ML is appropriate for lower-current designs. Both operate across -40°C to 125°C and are RoHS3 compliant.

Q: Is UP2UC-150-R suitable for -40°C operation?

A: No. UP2UC-150-R operates from -25°C to 85°C, which does not meet the original CDR95NP-150MC specification of -40°C to 100°C. This substitute is limited to applications with minimum operating temperature of -25°C or higher.

Q: How does DC resistance affect substitution?

A: DC resistance directly impacts power dissipation and thermal performance. The original CDR95NP-150MC specifies 46.8 mOhm maximum. P0751.153NLT (55 mOhm) and SDR1005-150ML (60 mOhm) exhibit higher resistance, resulting in increased I²R losses. SDR1305-150M and UP2UC-150-R (both 46 mOhm) match the original specification. For current-limited applications, higher resistance may be acceptable; for power-critical designs, lower-resistance options are preferred.

Q: Are all substitutes available in Tape & Reel packaging?

A: Yes. All listed substitute parts are available in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original CDR95NP-150MC packaging format is not specified in available data.

Q: What is the significance of saturation current ratings?

A: Saturation current indicates the threshold at which inductance begins to degrade. The original part saturates at 3.5 A. Substitutes range from 3 A (P0751.153NLT, SDR1005-150ML, UP2UC-150-R) to 3.7 A (SDR1305-150M). For applications operating near the 3 A continuous rating, SDR1305-150M provides additional margin before saturation occurs.

Q: Do all substitutes meet RoHS3 compliance?

A: Yes. All listed substitutes are RoHS3 compliant or RoHS compliant, meeting regulatory requirements equivalent to or exceeding the original CDR95NP-150MC specification.
