CDH53NP-100LC Equivalent & Substitute Parts

Part Overview

The CDH53NP-100LC is a 10 µH unshielded drum core wirewound inductor manufactured by Sumida America Components Inc. This surface mount component is rated for 1.23 A continuous current with a maximum DC resistance of 160mOhm and operates across the temperature range of -40°C to 100°C. The part is classified as Active and maintains ROHS3 compliance with MSL Level 1 rating. Equivalent and substitute parts are identified when design requirements permit tolerance variations, current rating adjustments, or thermal operating range modifications while maintaining core electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CDH53NP-100LC is permissible when the following core electrical and mechanical parameters are maintained or exceeded:

Critical Parameters for Substitution:

• Inductance value: 10 µH (exact match required)
• Core type: Ferrite drum core, wirewound, unshielded
• DC Resistance: 160mOhm maximum (equal or lower acceptable)
• Mounting: Surface mount, nonstandard package
• Compliance: ROHS3 and MSL Level 1 minimum

Allowable Variations:

• Current rating: Substitute must equal or exceed 1.23 A
• Tolerance: Substitute tolerance of ±20% or tighter acceptable
• Operating temperature: Substitute range must encompass or extend the -40°C to 100°C specification
• Packaging format: Tape & Reel (TR) maintained

The SDR6603-100M from Bourns Inc. qualifies as a substitute based on matching inductance, core material, DC resistance specification, and compliance requirements, with acceptable variations in current rating, tolerance, and operating temperature range.

Engineering Selection Recommendations

CDH53NP-100LC Selection Criteria:

• Primary choice when current requirement is 1.23 A or higher
• Preferred for applications with strict inductance tolerance requirements (±15%)
• Suitable for operating environments with maximum temperature of 100°C
• Active product status with 5700 units in stock

SDR6603-100M Selection Criteria:

• Acceptable substitute when circuit current requirement does not exceed 1.1 A
• Suitable for applications tolerating ±20% inductance tolerance
• Preferred for thermal environments extending to 125°C maximum operating temperature
• Active product status with 4900 units in stock
• Extended frequency characterization available (Q @ 2.52MHz: 17; Self Resonant Frequency: 35MHz)

Both parts maintain ROHS3 compliance, MSL Level 1 rating, and identical DC resistance specification. Selection between these components depends on circuit current demands and thermal operating envelope requirements.

Frequently Asked Questions (FAQ)

Q: Can SDR6603-100M replace CDH53NP-100LC in all applications?

A: Substitution is permissible only when the circuit current requirement does not exceed 1.1 A. The SDR6603-100M is rated for 1.1 A continuous current, compared to 1.23 A for the CDH53NP-100LC. Verify circuit current specifications before substitution.

Q: What is the impact of the ±20% tolerance on SDR6603-100M versus ±15% on CDH53NP-100LC?

A: The SDR6603-100M tolerance is wider by 5 percentage points. For applications requiring tighter inductance control, the CDH53NP-100LC is the appropriate choice. For applications with inductance tolerance budgets accommodating ±20%, the SDR6603-100M is acceptable.

Q: Are the physical dimensions compatible between these two parts?

A: Physical dimensions differ. CDH53NP-100LC measures 0.236" L x 0.205" W x 0.126" H (6.00mm x 5.20mm x 3.20mm). SDR6603-100M measures 0.260" L x 0.175" W x 0.115" H (6.60mm x 4.45mm x 2.92mm). PCB layout and mechanical clearance must be verified for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both CDH53NP-100LC and SDR6603-100M are ROHS3 compliant, carry MSL Level 1 rating, and share identical ECCN (EAR99) and HTSUS (8504.50.4000) classifications.

Q: What is the temperature operating range difference?

A: CDH53NP-100LC operates from -40°C to 100°C. SDR6603-100M operates from -40°C to 125°C. The SDR6603-100M provides extended high-temperature capability, making it suitable for thermal environments exceeding 100°C.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both CDH53NP-100LC and SDR6603-100M are supplied in Tape & Reel (TR) format, maintaining consistent handling and assembly compatibility.
