Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD1-150-R are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Inductance value: 15 µH (exact match required)
• Inductance tolerance: ±30% (exact match required)
• DC resistance: 50 mOhm maximum (exact match required)
• Current saturation (Isat): 3.6 A (exact match required)
• Core material: Ferrite shielded construction (exact match required)
• Mounting type: Surface Mount (exact match required)
• Test frequency: 100 kHz (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

Secondary Compatibility Parameters:

• Current rating: Substitute parts rated at 3.1 A are acceptable when the application does not require the full 3.35 A rating of the original part
• Operating temperature range: Substitute parts with extended or equivalent temperature ranges are acceptable
• Package dimensions: Minor dimensional variations within the nonstandard package classification are acceptable provided mounting compatibility is maintained
• Packaging format: Transition from bulk to Tape & Reel (TR) packaging is acceptable for manufacturing and procurement purposes

Two substitute parts meet these criteria: DR1040-150-R (Eaton - Electronics Division) and CDRH104RNP-150NC (Sumida America Components Inc.).

Parameter Comparison

Engineering Selection Recommendations

DR1040-150-R (Eaton - Electronics Division):

The DR1040-150-R is a direct manufacturer equivalent from Eaton - Electronics Division with active product status. This part maintains all critical electrical parameters identical to the CD1-150-R, including 15 µH inductance, ±30% tolerance, 50 mOhm maximum DC resistance, and 3.6 A saturation current. The continuous current rating is reduced from 3.35 A to 3.1 A; this substitution is valid for applications where the load current does not exceed 3.1 A. The operating temperature range extends from -40°C to 125°C, providing superior thermal performance compared to the original -40°C to 85°C specification. The part is ROHS3 compliant and available in Tape & Reel packaging with 2182 pieces in stock. Dimensional compatibility is maintained with identical height (4.00 mm) and negligible length/width variations (10.50 mm × 10.30 mm versus 10.50 mm × 10.40 mm).

CDRH104RNP-150NC (Sumida America Components Inc.):

The CDRH104RNP-150NC is a cross-manufacturer substitute from Sumida America Components Inc. with active product status. This part satisfies all mandatory electrical parameters: 15 µH inductance, ±30% tolerance, 50 mOhm maximum DC resistance, and 3.6 A saturation current. The continuous current rating is 3.1 A, consistent with the DR1040-150-R. The operating temperature range is -40°C to 100°C, exceeding the original specification. ROHS3 compliance is confirmed; REACH status is vendor undefined. Dimensional variations are minor (10.20 mm × 10.00 mm length/width with 4.00 mm height), maintaining surface mount compatibility. Inventory availability is substantial at 17,300 pieces. This option provides geographic and supply chain diversification through a second-source manufacturer.

Selection Criteria:

For applications requiring the full 3.35 A continuous current rating, neither substitute is appropriate. For applications operating at or below 3.1 A continuous current, both substitutes are electrically and mechanically compatible. The DR1040-150-R is recommended as the primary choice due to manufacturer continuity with the original part. The CDRH104RNP-150NC is recommended as a secondary option for supply chain resilience or when extended temperature performance to 125°C is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the DR1040-150-R replace the CD1-150-R in all applications?

A: The DR1040-150-R is electrically and mechanically compatible with the CD1-150-R provided the application does not require continuous current exceeding 3.1 A. The original part is rated for 3.35 A continuous current; the substitute is rated for 3.1 A. All other electrical parameters, including inductance, DC resistance, saturation current, and core material, are identical. Dimensional compatibility is maintained.

Q: What is the difference between the two substitute parts?

A: Both DR1040-150-R and CDRH104RNP-150NC share identical electrical specifications (15 µH, 50 mOhm DCR, 3.1 A rating, 3.6 A Isat). The primary differences are manufacturer (Eaton versus Sumida), operating temperature range (125°C maximum versus 100°C maximum), and minor dimensional variations (10.50 mm × 10.30 mm versus 10.20 mm × 10.00 mm). Both are ROHS3 compliant and available in Tape & Reel packaging.

Q: Are there any compliance or certification differences?

A: Both substitute parts are ROHS3 compliant. The DR1040-150-R confirms REACH compliance. The CDRH104RNP-150NC lists REACH status as vendor undefined. Both parts carry identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications. Moisture sensitivity level is 1 (Unlimited) for all three parts.

Q: Can I use these substitutes in high-temperature applications?

A: The DR1040-150-R operates to 125°C, exceeding both the original CD1-150-R (85°C) and the CDRH104RNP-150NC (100°C). For applications requiring operation above 85°C, the DR1040-150-R provides superior thermal margin. The CDRH104RNP-150NC supports operation to 100°C, suitable for applications between 85°C and 100°C.

Q: What are the packaging differences?

A: The CD1-150-R is supplied in bulk packaging. Both substitute parts are supplied in Tape & Reel (TR) format, which is standard for automated assembly processes. Tape & Reel packaging does not affect electrical or mechanical performance; it is a procurement and manufacturing convenience format.

Q: Are the dimensional differences significant?

A: Dimensional variations are minor. The CD1-150-R measures 10.50 mm × 10.40 mm × 4.00 mm (L × W × H). The DR1040-150-R measures 10.50 mm × 10.30 mm × 4.00 mm. The CDRH104RNP-150NC measures 10.20 mm × 10.00 mm × 4.00 mm. All three parts maintain the same height (4.00 mm) and are classified as nonstandard package. These variations are within typical manufacturing tolerances for surface mount inductors and do not affect PCB layout compatibility.

Q: Which substitute should I select for new designs?

A: For new designs, either substitute is acceptable provided the application current does not exceed 3.1 A. The DR1040-150-R is recommended as the primary choice due to manufacturer continuity with the original Eaton part and extended temperature range to 125°C. The CDRH104RNP-150NC is recommended as a secondary source for supply chain diversification.
