Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete CM15-2024 is permissible with the CT10-1530-G1 based on the following electrical and mechanical compatibility parameters:

Circuit Configuration Match: Both components are SPST-NO molded body reed switches, ensuring identical switching topology.

Current Compatibility: Both parts maintain a 500mA (AC/DC) switching current rating, meeting the load requirements of the original design.

Voltage Compatibility: The CT10-1530-G1 supports 140V AC and 200V DC switching voltages. The 200V DC rating maintains parity with the original CM15-2024 specification. For applications requiring 200V AC operation, the CT10-1530-G1's 140V AC rating represents a voltage reduction of 60V, which requires application-specific evaluation.

Power Rating: The CT10-1530-G1 is rated for 10W, compared to the 10VA rating of the CM15-2024. This represents an increase in power handling capability.

Mechanical Compatibility: Both components share Surface Mount mounting and Gull Wing termination, enabling direct footprint compatibility.

Environmental Compliance: Both components carry RoHS compliance and MSL-1 moisture sensitivity rating with unlimited shelf life capability.

Parameter Comparison

Engineering Selection Recommendations

The CT10-1530-G1 is a direct functional substitute for the obsolete CM15-2024, with primary advantages including active product status ensuring long-term supply availability and enhanced ROHS3 compliance certification. The substitute component carries equivalent or improved electrical ratings across DC switching voltage, power capacity, and thermal operating range.

For applications requiring 200V AC operation, the CT10-1530-G1's reduced AC voltage rating of 140V requires evaluation against actual circuit operating conditions. In applications where AC voltage does not exceed 140V, full compatibility is established. The extended operate range of 15 ~ 30AT in the substitute provides operational flexibility compared to the 10 ~ 15AT range of the original component.

Frequently Asked Questions (FAQ)

Q: Can the CT10-1530-G1 directly replace the CM15-2024 in all applications?

A: Direct substitution is permissible for applications where the AC switching voltage does not exceed 140V. For circuits operating at 200V AC, the voltage derating of the substitute component must be addressed at the system design level. DC applications at 200V are fully compatible. Both components share identical mounting footprints and termination styles, enabling board-level drop-in replacement where voltage specifications permit.

Q: What is the significance of the operate range difference between the two components?

A: The CM15-2024 operates within a 10 ~ 15AT (Ampere-Turns) magnetic activation range, while the CT10-1530-G1 extends this to 15 ~ 30AT. The substitute requires a stronger magnetic field for activation but maintains the same switching current capacity. System integration requires that the electromagnet or magnetic source in the application can deliver sufficient magnetic force to activate the 15 ~ 30AT operate range.

Q: What packaging formats are available for the CT10-1530-G1?

A: The CT10-1530-G1 is supplied in Cut Tape (CT) and Digi-Reel® packaging formats, enabling selection based on production volume and assembly requirements.

Q: How do the power ratings compare between the two components?

A: The CM15-2024 carries a 10VA power rating, while the CT10-1530-G1 is rated for 10W. Both ratings are based on the 500mA switching current specification. The 10W rating of the substitute indicates enhanced power dissipation capability and provides design margin for continuous operation at maximum current levels.

Q: Are both components RoHS compliant?

A: The CM15-2024 carries standard RoHS compliance certification. The CT10-1530-G1 carries ROHS3 compliance, representing the current and most restrictive RoHS certification standard. Systems requiring ROHS3 compliance can use the substitute without concern. Systems designed to the earlier RoHS standard are also compatible with ROHS3-certified components.
