CDH53-221JC Equivalent & Substitute Parts

Part Overview

The CDH53-221JC is a 220 µH unshielded drum core wirewound inductor manufactured by Sumida America Components Inc. This surface mount component is rated for 260 mA continuous current with a maximum DC resistance of 3.73 Ohm and operates across the temperature range of -30°C to 100°C. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDH53-221JC is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match):

• Inductance value: 220 µH
• Inductance tolerance: ±5%
• Current rating: 260 mA minimum
• DC resistance: 3.73 Ohm maximum
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters (Must Match):

• Mounting type: Surface Mount
• Physical footprint: 6.00 mm × 5.20 mm × 3.20 mm maximum height
• Package type: Nonstandard

Environmental Parameters (Must Match or Exceed):

• Operating temperature range: Minimum -30°C to 100°C
• Moisture sensitivity: MSL 1 or better

The CDH53NP-221JC qualifies as a direct substitute because it maintains identical electrical specifications, mechanical dimensions, and core construction while offering improved product status and regulatory compliance.

Parameter Comparison

Engineering Selection Recommendations

The CDH53NP-221JC is the direct equivalent substitute for the obsolete CDH53-221JC. Selection of the substitute part is justified on the following engineering grounds:

Product Status: The CDH53-221JC is classified as obsolete, creating supply chain risk. The CDH53NP-221JC maintains active product status with confirmed inventory availability (813 pieces in stock), ensuring procurement continuity.

Regulatory Compliance: The substitute part is ROHS3 compliant, whereas the main part is non-compliant. For applications subject to RoHS directives or customer requirements, the CDH53NP-221JC is the required selection.

Electrical and Mechanical Equivalence: All critical electrical parameters (inductance, current rating, DC resistance, core material, shielding) and mechanical parameters (dimensions, mounting type) are identical between the two parts. Direct circuit substitution is supported without design modification.

Environmental Performance: The substitute part extends the lower operating temperature limit to -40°C, providing enhanced performance margin in cold environment applications while maintaining the upper limit at 100°C.

Packaging Consideration: The substitute is supplied in Tape & Reel format, which is standard for automated assembly processes. If bulk packaging is required, this represents the only packaging difference and does not affect electrical or mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can CDH53NP-221JC be used as a direct replacement for CDH53-221JC in existing designs?

A: Yes. The CDH53NP-221JC is electrically and mechanically identical to the CDH53-221JC. All critical parameters including inductance (220 µH), current rating (260 mA), DC resistance (3.73 Ohm max), core material (ferrite), shielding (unshielded), and physical dimensions (6.00 mm × 5.20 mm × 3.20 mm) are identical. No circuit design changes are required.

Q: What is the difference between CDH53-221JC and CDH53NP-221JC?

A: The primary differences are product status, regulatory compliance, packaging format, and operating temperature range. The CDH53-221JC is obsolete and RoHS non-compliant, while the CDH53NP-221JC is active, ROHS3 compliant, and rated for -40°C to 100°C (versus -30°C to 100°C). The substitute is supplied in Tape & Reel packaging rather than bulk.

Q: Are there any compatibility issues when switching from CDH53-221JC to CDH53NP-221JC?

A: No compatibility issues exist for electrical or mechanical performance. The only consideration is packaging format: CDH53NP-221JC is supplied in Tape & Reel, which is standard for pick-and-place assembly. If manual or bulk handling is required, this packaging difference must be accommodated in procurement and assembly processes.

Q: Why is the CDH53-221JC classified as obsolete?

A: The CDH53-221JC is listed as obsolete by the manufacturer. The CDH53NP-221JC, which is functionally equivalent and currently active, is the recommended alternative for new designs and ongoing production.

Q: Does the extended temperature range of CDH53NP-221JC affect circuit performance?

A: The extended lower temperature limit (-40°C versus -30°C) provides additional performance margin in cold environments. The upper limit remains 100°C. This change does not negatively affect performance in applications previously qualified to -30°C to 100°C.

Q: Is RoHS compliance a requirement for using CDH53NP-221JC?

A: RoHS compliance is required by regulation in many markets and by customer specifications. The CDH53NP-221JC is ROHS3 compliant, making it the appropriate choice for applications subject to RoHS directives. The original CDH53-221JC is non-compliant and may not be acceptable for new designs or regulated applications.
