CCM-2412DF Equivalent & Substitute Parts

Part Overview

The CCM-2412DF is an isolated module DC-DC converter manufactured by TDK-Lambda Americas Inc, designed to provide dual output voltages of +12V and -12V at 125mA each from an 18V to 36V input supply. This 3W converter operates across a temperature range of -20°C to 70°C with 78% efficiency and includes over-current protection (OCP). The CCM-2412DF is classified as obsolete, necessitating identification of active substitute components for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CCM-2412DF is determined by the following critical parameters that must remain compatible:

Input Voltage Compatibility: The substitute must accept the same 18V to 36V input range to function within existing power distribution systems.

Output Configuration: The substitute must provide dual outputs with symmetrical voltage magnitudes. The CCM-2412DF delivers +12V and -12V; substitutes with adjustable or wider output voltage ranges (such as 12V ~ 15V and -12V ~ -15V) are acceptable provided the nominal operating point includes the original 12V/-12V specification.

Current Capacity: Each output must support a minimum of 125mA to maintain equivalent load-driving capability.

Power Rating: The 3W power budget must be maintained or exceeded.

Isolation Voltage: The 500V isolation specification must be preserved for safety and regulatory compliance.

Mounting and Package: Through-hole mounting and DIP module packaging are required for mechanical compatibility with existing PCB layouts.

Number of Outputs: Dual-output configuration is mandatory; single-output converters are not substitutable.

The CC3-2412DF-E meets all these criteria while offering an active product status, extended operating temperature range, and improved control features.

Engineering Selection Recommendations

The CC3-2412DF-E is the manufacturer-recommended substitute for the obsolete CCM-2412DF. Selection of this substitute is based on the following engineering factors:

Product Status: The CCM-2412DF is obsolete and no longer manufactured. The CC3-2412DF-E maintains active product status with ongoing manufacturing support and availability.

Regulatory Compliance: Both components share identical ECCN (EAR99) and HTSUS (8504.40.9580) classifications, ensuring equivalent export and tariff treatment. The CC3-2412DF-E is RoHS Compliant and REACH Unaffected, meeting current environmental regulations.

Electrical Compatibility: The CC3-2412DF-E maintains the same input voltage range (18V - 36V), output current capacity (125mA per output), power rating (3W), and isolation voltage (500V) as the original part. The adjustable output voltage range (12V ~ 15V and -12V ~ -15V) encompasses the fixed 12V/-12V specification of the CCM-2412DF, providing functional equivalence at the nominal operating point.

Operating Temperature Enhancement: The CC3-2412DF-E extends the operating temperature range to -40°C ~ 85°C, compared to the CCM-2412DF range of -20°C ~ 70°C, providing improved thermal performance for demanding applications.

Control Features: The CC3-2412DF-E includes Enable and Active Low control features, offering enhanced functionality not present in the original part.

Package Consideration: The CC3-2412DF-E uses a 7-DIP Module package compared to the 6-DIP Module of the CCM-2412DF. Physical dimensions are slightly reduced (22.9mm x 16.6mm x 8.5mm versus 28.4mm x 20.6mm x 8.4mm), requiring PCB layout verification for pin compatibility and mechanical fit.

Frequently Asked Questions (FAQ)

Q: Can the CC3-2412DF-E directly replace the CCM-2412DF in existing designs?

A: The CC3-2412DF-E is electrically compatible with the CCM-2412DF for applications requiring 12V and -12V outputs at 125mA from an 18V to 36V input. However, the package change from 6-DIP to 7-DIP requires verification of PCB footprint compatibility and pin assignment alignment before implementation.

Q: What is the significance of the adjustable output voltage range on the CC3-2412DF-E?

A: The CC3-2412DF-E provides output voltage ranges of 12V ~ 15V and -12V ~ -15V, which encompass the fixed 12V and -12V outputs of the CCM-2412DF. This design allows the substitute to serve multiple voltage requirements while maintaining compatibility with the original 12V/-12V specification.

Q: Are there differences in isolation voltage between the two parts?

A: No. Both the CCM-2412DF and CC3-2412DF-E maintain 500V isolation voltage, ensuring equivalent safety and regulatory compliance for isolated power delivery applications.

Q: How does the extended operating temperature range of the CC3-2412DF-E affect substitution?

A: The CC3-2412DF-E operating range of -40°C ~ 85°C exceeds the CCM-2412DF range of -20°C ~ 70°C. This enhancement provides greater thermal margin and enables operation in more demanding environmental conditions without derating.

Q: What is the impact of the package change from 6-DIP to 7-DIP?

A: The package change requires PCB layout modification. The CC3-2412DF-E has a different pin count and physical footprint. Existing PCB designs using the 6-DIP CCM-2412DF footprint must be updated to accommodate the 7-DIP CC3-2412DF-E package before component substitution.

Q: Are the input voltage specifications identical between both parts?

A: Yes. Both the CCM-2412DF and CC3-2412DF-E accept input voltages from 18V to 36V, ensuring compatibility with existing power supply architectures.

Q: What is the significance of the Enable and Active Low control features on the CC3-2412DF-E?

A: The CC3-2412DF-E includes Enable and Active Low control features that allow external logic to control converter operation. The CCM-2412DF does not specify these features. These additional controls provide enhanced system-level functionality for power management applications.

Q: Is the 3W power rating maintained in the substitute?

A: Yes. Both the CCM-2412DF and CC3-2412DF-E are rated at 3W, maintaining equivalent power delivery capability and thermal characteristics.

Q: What certifications apply to the CC3-2412DF-E?

A: The CC3-2412DF-E is RoHS Compliant and REACH Unaffected, meeting current environmental and chemical safety regulations. Both parts share the same ECCN (EAR99) and HTSUS (8504.40.9580) classifications.
