CBC3225T100M Equivalent & Substitute Parts

Part Overview

The CBC3225T100M is a 10 µH unshielded drum core wirewound inductor manufactured by Taiyo Yuden, rated for 900 mA continuous current with a maximum DC resistance of 172.9 mOhm. This surface mount component is housed in a 1210 (3225 Metric) package and operates across the temperature range of -40°C to 105°C.

The CBC3225T100M carries a product status designation of "Not For New Designs," indicating that Taiyo Yuden has discontinued active development and promotion of this component. This status necessitates identification of functionally equivalent alternatives for ongoing production requirements, maintenance applications, and new design implementations where the electrical and mechanical specifications remain suitable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CBC3225T100M is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Inductance value: 10 µH
• Inductance tolerance: ±20%
• Current rating: 900 mA minimum
• Package / Case: 1210 (3225 Metric)
• Mounting type: Surface Mount
• Core material: Ferrite
• Shielding configuration: Unshielded
• Operating temperature range: -40°C to 105°C minimum
• Self resonant frequency: 23 MHz

Acceptable Variation Parameters:

• DC Resistance (DCR): Substitute parts with lower DCR values are functionally compatible, as reduced resistance improves efficiency without affecting circuit operation
• Product status: Obsolete or discontinued parts are acceptable substitutes provided all electrical and mechanical parameters align

The KEMET L1210R100MDWIT meets all mandatory matching criteria and qualifies as a direct substitute. This component exhibits superior DC resistance performance (133 mOhm versus 172.9 mOhm maximum), representing an engineering improvement while maintaining full compatibility with the original specification.

Parameter Comparison

Engineering Selection Recommendations

For Existing Production Continuity: The KEMET L1210R100MDWIT provides direct functional substitution for the CBC3225T100M. Both components maintain identical electrical specifications across inductance, current rating, operating temperature, and frequency characteristics. The KEMET substitute exhibits lower DC resistance, which reduces power dissipation and improves thermal performance in the application circuit.

Compliance Considerations: Both the original CBC3225T100M and the substitute L1210R100MDWIT carry ROHS3 compliance certification and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage protocols. No additional environmental or regulatory constraints differentiate these components.

Product Status Impact: The CBC3225T100M designation as "Not For New Designs" reflects manufacturer discontinuation of active support. The KEMET L1210R100MDWIT, while marked as Obsolete, remains functionally equivalent and suitable for applications where the specified electrical and mechanical parameters are required. Component availability should be verified through authorized distributors prior to design commitment.

Frequently Asked Questions (FAQ)

Q: Can the KEMET L1210R100MDWIT be used as a direct replacement for the CBC3225T100M without circuit modification?

A: Yes. The L1210R100MDWIT meets all mandatory electrical and mechanical specifications of the CBC3225T100M. The lower DC resistance (133 mOhm versus 172.9 mOhm maximum) represents an improvement that does not require circuit redesign. Both components share identical inductance values, current ratings, package dimensions, and operating temperature ranges.

Q: What is the significance of the lower DC resistance in the KEMET substitute?

A: The KEMET L1210R100MDWIT exhibits 133 mOhm DC resistance compared to the 172.9 mOhm maximum of the CBC3225T100M. This 23% reduction in series resistance decreases power dissipation (I²R losses) and reduces thermal stress on the component during operation at rated current levels. This characteristic improves reliability and efficiency without affecting circuit functionality.

Q: Are there packaging differences between these components?

A: No. Both the CBC3225T100M and L1210R100MDWIT utilize the 1210 (3225 Metric) surface mount package with identical physical dimensions: 0.126" L × 0.098" W (3.20 mm × 2.50 mm) and maximum seated height of 0.106" (2.70 mm). PCB layout and assembly processes require no modification.

Q: What is the difference between "Not For New Designs" and "Obsolete" product status?

A: "Not For New Designs" indicates the manufacturer has ceased active promotion and development but may continue limited production. "Obsolete" indicates the manufacturer has completely discontinued the product line. For component selection purposes, both statuses necessitate identification of alternatives. Availability of either component should be confirmed through authorized distributors.

Q: Do both components meet the same environmental and compliance standards?

A: Yes. Both the CBC3225T100M and L1210R100MDWIT carry ROHS3 compliance certification, MSL 1 (Unlimited) moisture sensitivity ratings, and EAR99 ECCN classification. No additional environmental qualification or regulatory approval is required for substitution.

Q: What inductance tolerance applies to both components?

A: Both components carry ±20% inductance tolerance at the 100 kHz test frequency. This tolerance specification applies equally to the CBC3225T100M and L1210R100MDWIT, ensuring consistent circuit performance across the component population.
