Equivalent & Substitute Parts for CCK-4812DF

Part Overview

The TDK-Lambda Americas Inc CCK-4812DF is an obsolete isolated module DC-DC converter designed for ITE (Commercial) applications. It provides dual outputs of +12V and -12V at 60mA each, operating from a 36V to 72V input range with a power rating of 1.44W. Due to its discontinued status, identifying suitable direct alternatives is necessary for ongoing engineering support and system maintenance.

Substitute Part Grouping Explanation

The substitute part selection is strictly based on matching and allowable ranges for key parameters: module type (isolated), number of outputs, input voltage range, output voltage(s) and maximum current, power output, isolation voltage, through-hole mounting, application domain, and package type. The substitute part must operate within or exceed each parameter without violating the functional specification of the original CCK-4812DF.

Engineering Selection Recommendations

The original CCK-4812DF is obsolete. The substitute CC1R5-4812DF-E is active and classified as RoHS compliant with REACH unaffected status. Both parts are in the same ECCN and HTSUS categories. Moisture Sensitivity Level (MSL) classification remains unchanged. These regulatory and status parameters align the CC1R5-4812DF-E as a qualified substitute based strictly on provided compliance and certification data.

Frequently Asked Questions (FAQ)

Q: What are the primary criteria for selecting equivalent and substitute DC-DC converters in this category?
A: Key criteria include module type, number of outputs, input and output voltage ranges, output current, output power, isolation voltage, mounting type, application category, and compliance status.

Q: Are there differences in the mounting or package between CCK-4812DF and CC1R5-4812DF-E?
A: Yes, the CCK-4812DF uses a 6-DIP Module package; the CC1R5-4812DF-E uses a 7-DIP Module package. Both use through-hole mounting.

Q: Does the substitute part meet the same application requirements?
A: Both parts are rated for ITE (Commercial) applications.

Q: Are the environmental and compliance requirements equivalent?
A: The substitute part holds MSL 1 (Unlimited), with RoHS and REACH statuses provided, and shares ECCN and HTSUS designations with the original.

Q: How do the output voltages compare?
A: The CCK-4812DF provides fixed ±12V outputs, while the CC1R5-4812DF-E provides adjustable ±12V to ±15V outputs.

Q: Can the substitute operate within the original's temperature range?
A: The substitute operates over a wider temperature range.
