CCM-2405SF DC DC Converter Equivalent & Substitute Parts

Part Overview

The CCM-2405SF is an isolated module DC DC converter manufactured by TDK-Lambda Americas Inc, designed to convert 18V to 36V input to a regulated 5V output at 600mA maximum current. This 3W converter is classified as obsolete, which necessitates identification of active equivalent parts for continued system support and new designs. The part features 500V isolation, through-hole mounting in a 6-DIP module package, and is rated for commercial ITE applications with operating temperatures from -20°C to 70°C.

Engineering Selection Recommendations

The CC3-2405SF-E is the appropriate selection for applications currently using or requiring the CCM-2405SF converter. The substitute part maintains full electrical equivalence across all critical parameters: input voltage range, output voltage, current capacity, power rating, and isolation voltage.

The CC3-2405SF-E offers the following advantages:

Product Lifecycle: Active status ensures long-term availability, manufacturer support, and continued production, eliminating obsolescence risk associated with the CCM-2405SF.

Compliance: The CC3-2405SF-E carries RoHS Compliant and REACH Unaffected certifications, meeting current regulatory requirements for commercial and industrial applications.

Operating Range: Extended operating temperature range (-40°C to 85°C versus -20°C to 70°C) provides greater thermal margin for demanding environments.

Package Consideration: The CC3-2405SF-E uses a 7-DIP module package compared to the 6-DIP module of the CCM-2405SF. Physical dimensions differ slightly (22.9mm × 16.6mm × 8.5mm versus 28.4mm × 20.6mm × 8.4mm). PCB layout verification is required to confirm fit within existing mounting footprints.

Frequently Asked Questions (FAQ)

Q: Are the CCM-2405SF and CC3-2405SF-E electrically interchangeable?

A: Yes. Both converters provide identical electrical specifications: 18V to 36V input, 5V output at 600mA maximum, 3W power rating, and 500V isolation. The electrical performance and load characteristics are equivalent.

Q: What is the primary difference between these two parts?

A: The CCM-2405SF is obsolete, while the CC3-2405SF-E is active. The CC3-2405SF-E also features an extended operating temperature range (-40°C to 85°C), RoHS compliance, and a 7-DIP package versus the 6-DIP package of the CCM-2405SF.

Q: Will the CC3-2405SF-E fit in the same PCB footprint as the CCM-2405SF?

A: Physical dimensions differ between the two parts. The CCM-2405SF measures 28.4mm × 20.6mm × 8.4mm, while the CC3-2405SF-E measures 22.9mm × 16.6mm × 8.5mm. The CC3-2405SF-E is smaller in length and width. PCB layout and mounting hole spacing must be verified for compatibility with existing designs.

Q: What does the 7-DIP versus 6-DIP package designation mean?

A: DIP refers to Dual Inline Package, with the number indicating pin count. The 6-DIP has six pins, while the 7-DIP has seven pins. Pin configuration and spacing may differ, requiring verification against schematic and PCB design files.

Q: Is the CC3-2405SF-E suitable for new designs?

A: Yes. The active product status, extended temperature range, and regulatory compliance certifications make the CC3-2405SF-E the appropriate choice for new commercial ITE applications requiring isolated 5V DC conversion from 18V to 36V input sources.

Q: What is the significance of RoHS compliance on the CC3-2405SF-E?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the part meets EU directive requirements restricting lead, cadmium, mercury, and other hazardous materials. This certification is required for many commercial and consumer applications sold in regulated markets.

Q: Can I use the CCM-2405SF in new designs?

A: No. The CCM-2405SF is classified as obsolete, indicating discontinued production and unavailable inventory for new procurement. The CC3-2405SF-E must be used for new designs to ensure component availability and manufacturer support.
