CD1-220-R Equivalent & Substitute Parts Reference

Part Overview

The CD1-220-R is a 22 µH shielded drum core wirewound inductor manufactured by Eaton - Electronics Division. This surface mount component is rated for 2.77 A continuous current with a maximum DC resistance of 73 mOhm and operates across the temperature range of -40°C to 85°C. The part is classified as obsolete, necessitating identification of active equivalent components for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CD1-220-R are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Primary Electrical Parameters:

• Inductance value: 22 µH (exact match required)
• Inductance tolerance: ±30% (exact match required)
• DC resistance: 73 mOhm Max (exact match required)
• Saturation current: 2.9 A (exact match required)
• Shielding: Shielded (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)
• Moisture sensitivity: MSL 1 (exact match required)

Acceptable Variations:

• Current rating: Substitute parts rated at 2.5 A are acceptable as this exceeds the minimum saturation current of 2.9 A
• Operating temperature range: Substitute parts with extended or equivalent temperature ranges are acceptable
• Product status: Active substitutes are preferred over obsolete parts for procurement continuity
• Packaging format: Tape & Reel (TR) and Cut Tape (CT) formats are acceptable for surface mount assembly

Frequently Asked Questions (FAQ)

Q: Can the DR1040-220-R directly replace the CD1-220-R in existing designs?

A: Yes. The DR1040-220-R meets all electrical specifications of the CD1-220-R: 22 µH inductance, ±30% tolerance, 73 mOhm DC resistance, and 2.9 A saturation current. The extended temperature range (-40°C to 125°C) provides additional operational margin. Surface mount package compatibility is confirmed. No circuit redesign is required.

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

A: Both DR1040-220-R and CDRH104RNP-220NC meet identical electrical specifications. The primary differences are: manufacturer (Eaton vs. Sumida), packaging format (Tape & Reel vs. Cut Tape/Digi-Reel), operating temperature range (125°C vs. 100°C maximum), and physical dimensions (10.50mm x 10.30mm vs. 10.20mm x 10.00mm). Selection depends on assembly equipment compatibility and temperature requirements.

Q: Why is the CD1-220-R classified as obsolete?

A: The CD1-220-R is listed as obsolete by Eaton - Electronics Division. Active equivalent parts are available from the same manufacturer (DR1040-220-R) and alternative suppliers (CDRH104RNP-220NC). For new designs and ongoing production, selection of an active part is recommended to ensure long-term supply availability.

Q: Are there any current rating differences between the main part and substitutes?

A: The CD1-220-R is rated for 2.77 A continuous current, while both substitutes are rated for 2.5 A. However, all three parts share the same saturation current of 2.9 A. The saturation current represents the absolute maximum current before inductance degradation occurs. For applications operating below 2.5 A, both substitutes are fully compatible. For applications requiring the full 2.77 A rating, the CD1-220-R should be retained if available.

Q: What is the significance of the ±30% inductance tolerance?

A: The ±30% tolerance applies to all three parts and indicates the acceptable range of inductance variation from the nominal 22 µH value. This tolerance is inherent to ferrite drum core wirewound inductor manufacturing. Circuit designs must account for this tolerance range. All three parts are equivalent in this specification.

Q: Are the substitute parts RoHS and REACH compliant?

A: Yes. Both DR1040-220-R and CDRH104RNP-220NC are ROHS3 compliant and REACH unaffected. Compliance status for the CD1-220-R is not specified in available documentation. For applications requiring regulatory compliance certification, the active substitute parts are recommended.

Q: What packaging formats are available?

A: The CD1-220-R packaging format is not specified. The DR1040-220-R is supplied in Tape & Reel (TR) format for automated pick-and-place assembly. The CDRH104RNP-220NC is available in Cut Tape (CT) and Digi-Reel® formats. Selection should align with assembly equipment capabilities and procurement preferences.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, for surface mount assembly. All three parts are surface mount components with identical mounting type classification. Physical dimensions are similar (approximately 10.2mm to 10.5mm length and 10.0mm to 10.4mm width with 4.0mm seated height). Verify PCB footprint compatibility with actual component dimensions before assembly. Packaging format (Tape & Reel vs. Cut Tape) affects handling and feeder compatibility, not PCB placement.
