Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD1-100-R are identified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters:

• Inductance value: 10 µH (exact match required)
• DC resistance: 35 mOhm maximum (exact match required)
• Saturation current: 4.4 A (exact match required)
• Inductance tolerance: ±30% (exact match required)
• Shielding: Shielded configuration (exact match required)
• Test frequency: 100 kHz (exact match required)

Mechanical Parameters:

• Mounting type: Surface mount (exact match required)
• Package classification: Nonstandard (exact match required)
• Height seated maximum: 4.00 mm (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)

Operational Parameters:

• Operating temperature range: Must encompass or equal the original specification

The identified substitute parts meet these criteria while offering active product status and improved compliance certifications.

Engineering Selection Recommendations

DR1040-100-R (Eaton - Electronics Division)

The DR1040-100-R is the primary direct substitute for the CD1-100-R. Both components are manufactured by Eaton - Electronics Division and share identical electrical specifications: 10 µH inductance, 35 mOhm DC resistance, 4.4 A saturation current, and ±30% tolerance. The DR1040-100-R is classified as active product status, ensuring long-term availability and supply chain continuity. The component extends the operating temperature range to -40°C to 125°C, providing enhanced thermal performance beyond the original specification. RoHS3 compliance and REACH unaffected status confirm regulatory alignment with current environmental standards. The DR1040-100-R is supplied in Tape & Reel packaging, supporting automated assembly processes.

CDRH104RNP-100NC (Sumida America Components Inc.)

The CDRH104RNP-100NC is an alternative substitute manufactured by Sumida America Components Inc. This component maintains the same 10 µH inductance, 35 mOhm DC resistance, 4.4 A saturation current, and ±30% tolerance as the CD1-100-R. The CDRH104RNP-100NC is active product status with RoHS3 compliance and REACH unaffected certification. The operating temperature range extends to -40°C to 100°C. Physical dimensions are 10.20 mm length by 10.00 mm width with 4.00 mm seated height, maintaining compatibility with the original nonstandard package footprint. This part is supplied in Tape & Reel packaging.

Current Rating Consideration

Both substitute parts are rated for 3.8 A continuous current, compared to the CD1-100-R's 4 A rating. Both maintain identical 4.4 A saturation current specifications. Applications operating at or below 3.8 A continuous current are fully compatible. Applications requiring the full 4 A continuous current rating must evaluate circuit design margins and thermal management accordingly.

Frequently Asked Questions (FAQ)

Q: Can the DR1040-100-R directly replace the CD1-100-R in existing designs?

A: The DR1040-100-R meets all electrical and mechanical parameters of the CD1-100-R. The continuous current rating is 3.8 A versus 4 A on the original part. If the design operates at or below 3.8 A, direct substitution is applicable. Both parts share identical saturation current (4.4 A), inductance (10 µH), DC resistance (35 mOhm), and physical dimensions (4.00 mm height).

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

A: Both DR1040-100-R and CDRH104RNP-100NC meet the electrical specifications of the CD1-100-R. The primary differences are manufacturer (Eaton versus Sumida), operating temperature range (125°C versus 100°C maximum), and physical dimensions (10.50 mm × 10.30 mm versus 10.20 mm × 10.00 mm). Both are active products with RoHS3 compliance and REACH unaffected status.

Q: Are the physical dimensions compatible with the original CD1-100-R footprint?

A: The DR1040-100-R maintains identical dimensions to the CD1-100-R: 10.50 mm length, 10.40 mm width, and 4.00 mm seated height. The CDRH104RNP-100NC has slightly smaller dimensions: 10.20 mm length and 10.00 mm width, with identical 4.00 mm seated height. Both are compatible with the nonstandard package classification and surface mount mounting type.

Q: What compliance certifications apply to the substitute parts?

A: Both DR1040-100-R and CDRH104RNP-100NC are RoHS3 compliant and REACH unaffected. Both carry EAR99 ECCN classification and 8504.50.4000 HTSUS code. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Why is the continuous current rating lower on the substitute parts?

A: The DR1040-100-R and CDRH104RNP-100NC are rated for 3.8 A continuous current compared to the CD1-100-R's 4 A. Both maintain the same 4.4 A saturation current. This represents a 5% reduction in continuous current rating. Circuit designs operating below 3.8 A experience no functional impact.

Q: What packaging formats are available for the substitute parts?

A: Both DR1040-100-R and CDRH104RNP-100NC are supplied in Tape & Reel (TR) packaging, supporting automated pick-and-place assembly. The CD1-100-R packaging format was not specified in the original documentation.

Q: Are there inventory considerations for these substitute parts?

A: DR1040-100-R inventory is 25,219 pieces in stock. CDRH104RNP-100NC inventory is 1,299 pieces in stock. Both represent active products with established supply chains, contrasting with the CD1-100-R's obsolete status and limited remaining inventory of 777 pieces.
