Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD1-1R5-R are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Critical Matching Parameters:

• Inductance value: 1.5 µH
• Inductance tolerance: ±30%
• DC resistance: 8.1 mOhm Max
• Saturation current: 10 A
• Core material: Ferrite
• Shielding: Shielded
• Mounting type: Surface Mount
• Test frequency: 100 kHz
• MSL rating: 1 (Unlimited)

Acceptable Variation Parameters:

• Current rating: Substitute parts rated at 6.5 A are acceptable for applications where the main part's 8.3 A rating exceeds system requirements
• Operating temperature: Substitute parts with extended temperature ranges (-40°C to 100°C or -40°C to 125°C) are compatible with the original -40°C to 85°C specification
• Physical dimensions: Minor variations within the nonstandard package classification are acceptable provided mounting compatibility is maintained
• Product status: Active status substitutes are preferred to ensure long-term availability

Engineering Selection Recommendations

DR1040-1R5-R (Direct Manufacturer Substitute):

The DR1040-1R5-R is manufactured by Eaton - Electronics Division, the same manufacturer as the obsolete CD1-1R5-R. This part maintains identical electrical specifications for inductance (1.5 µH), tolerance (±30%), DC resistance (8.1 mOhm Max), and saturation current (10 A). The primary difference is a reduced continuous current rating of 6.5 A compared to the original 8.3 A. This substitute is suitable for applications where the system current requirement does not exceed 6.5 A. The DR1040-1R5-R features an extended operating temperature range of -40°C to 125°C, providing enhanced thermal performance. The part holds Active product status and is ROHS3 compliant, ensuring regulatory compliance and long-term availability. Physical dimensions are nearly identical, with only a 0.1mm reduction in width. Tape & Reel packaging is available.

CDRH104RNP-1R5NC (Cross-Manufacturer Substitute):

The CDRH104RNP-1R5NC is manufactured by Sumida America Components Inc. and provides equivalent electrical performance with identical inductance (1.5 µH), tolerance (±30%), DC resistance (8.1 mOhm Max), and saturation current (10 A). Like the DR1040-1R5-R, this part is rated for 6.5 A continuous current. The operating temperature range is -40°C to 100°C, which encompasses the original specification. This substitute is ROHS3 compliant and REACH unaffected. Physical dimensions are slightly smaller (10.20mm x 10.00mm versus 10.50mm x 10.40mm), with identical height. The CDRH104RNP-1R5NC is Active status and available in Tape & Reel packaging.

Selection Criteria:

For applications requiring the full 8.3 A continuous current rating of the original CD1-1R5-R, neither substitute is appropriate. For applications operating at 6.5 A or below, both substitutes are electrically equivalent. The DR1040-1R5-R is recommended as the primary choice due to manufacturer continuity with Eaton. The CDRH104RNP-1R5NC is recommended as a secondary option when DR1040-1R5-R availability is constrained. Both substitutes provide improved product status (Active versus Obsolete) and regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the DR1040-1R5-R replace the CD1-1R5-R in all applications?

A: The DR1040-1R5-R is electrically equivalent for inductance, tolerance, DC resistance, and saturation current. However, the continuous current rating is reduced from 8.3 A to 6.5 A. Substitution is valid only for applications where the system current does not exceed 6.5 A. If your application requires continuous current above 6.5 A, this substitute is not appropriate.

Q: What are the key electrical parameters that must match for substitution?

A: The critical parameters are inductance value (1.5 µH), inductance tolerance (±30%), DC resistance (8.1 mOhm Max), saturation current (10 A), core material (Ferrite), and shielding (Shielded). All substitute parts match these specifications exactly.

Q: Are there differences in physical dimensions between the main part and substitutes?

A: The DR1040-1R5-R has dimensions of 10.50mm L x 10.30mm W x 4.00mm H, compared to the CD1-1R5-R at 10.50mm L x 10.40mm W x 4.00mm H. The CDRH104RNP-1R5NC is 10.20mm L x 10.00mm W x 4.00mm H. All three parts have identical height. These minor dimensional variations are within the nonstandard package classification and do not affect mounting compatibility for standard surface mount applications.

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

A: The DR1040-1R5-R is classified as a direct substitute because it is manufactured by the same company (Eaton - Electronics Division) as the original part. The CDRH104RNP-1R5NC is a similar substitute from a different manufacturer (Sumida America Components Inc.). Both are electrically equivalent and functionally interchangeable within the specified current rating.

Q: Why is the product status important?

A: The CD1-1R5-R is classified as Obsolete, meaning it is no longer in active production and inventory will eventually be depleted. The substitute parts (DR1040-1R5-R and CDRH104RNP-1R5NC) are both Active status, ensuring continued availability for future procurement and design revisions.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both the DR1040-1R5-R and CDRH104RNP-1R5NC are ROHS3 compliant and REACH unaffected. The original CD1-1R5-R compliance status is not specified in the provided data.

Q: What is the operating temperature range for each part?

A: The CD1-1R5-R operates from -40°C to 85°C. The DR1040-1R5-R extends this to -40°C to 125°C. The CDRH104RNP-1R5NC operates from -40°C to 100°C. Both substitutes cover the original temperature specification and provide extended thermal performance.

Q: Is packaging format important for substitution?

A: The original CD1-1R5-R packaging format is not specified. Both substitute parts are available in Tape & Reel (TR) packaging, which is standard for surface mount component automation. Confirm that your assembly process is compatible with Tape & Reel format.
