Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CMT-01202 is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 2 mH @ 1 kHz (exact match required)
• Number of lines: 2-line configuration (exact match required)
• Mounting type: Through hole (exact match required)
• Package configuration: Vertical, 4 pin (exact match required)
• Voltage rating: 250V AC minimum (equal or higher acceptable)

Secondary Compatibility Criteria:

• Current rating: 2A minimum (equal or higher acceptable)
• DC resistance: 150 mOhm maximum (lower values acceptable)

The substitute part SS11VL-R22020 meets all primary matching criteria and exceeds secondary compatibility requirements with a higher current rating (2.2A) and lower DC resistance (120 mOhm).

The SS11VL-R22020 carries active product status, ensuring ongoing availability and supply chain support. The component is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. Operating temperature range of -25°C to 120°C provides extended thermal performance compared to the obsolete CMT-01202.

Physical dimensions (22.00mm L x 14.50mm W x 19.50mm H) are compatible with through-hole PCB layouts designed for the CMT-01202 vertical 4-pin configuration.

Frequently Asked Questions (FAQ)

Q: Can SS11VL-R22020 directly replace CMT-01202 in existing designs?

A: Yes. The SS11VL-R22020 meets all electrical and mechanical specifications required for CMT-01202 applications. Identical inductance values, line configuration, voltage rating, and through-hole mounting ensure functional equivalence. The higher current rating and lower DC resistance of the substitute provide equal or improved performance.

Q: What are the physical compatibility considerations?

A: Both components use vertical, 4-pin through-hole packages. The SS11VL-R22020 dimensions (22.00mm L x 14.50mm W x 19.50mm H) are compatible with PCB layouts designed for CMT-01202. Pin spacing and mounting footprint are equivalent.

Q: Does the lower DC resistance of SS11VL-R22020 affect circuit operation?

A: No. Lower DC resistance (120 mOhm versus 150 mOhm) represents improved performance. This reduces power dissipation and heat generation in the component, benefiting overall circuit efficiency without altering filtering characteristics.

Q: Are there regulatory or compliance differences between these parts?

A: The SS11VL-R22020 provides enhanced compliance documentation. ROHS3 compliance and REACH unaffected status meet current regulatory requirements. The CMT-01202, being obsolete, may lack current certification documentation.

Q: What is the current availability status of each part?

A: CMT-01202 inventory is limited (894 pieces reported). SS11VL-R22020 is actively manufactured with higher inventory availability (1138 pieces reported), ensuring reliable supply for new production and replacement applications.
