Key Parameters

Substitute Part Grouping Explanation

Substitution for CCM-0503SF is limited to DC DC converter modules matching the following parameters: manufacturer, module type (isolated), number of outputs (1), input voltage range (4.5V–9V), output voltage (3.3V), current output equal to or greater than 600mA, isolation voltage (500V), through-hole mounting, commercial ITE application support, and similar package cases. Only parts explicitly listed in the provided input and verified to match or exceed these criteria qualify for substitution.

Parameter Comparison

Engineering Selection Recommendations

CCM-0503SF is obsolete. CC3-0503SF-E is active and RoHS compliant. Both models have EAR99 classification and HTSUS 8504.40.9580, with identical input voltage range, output voltage, and isolation. CC3-0503SF-E meets or exceeds CCM-0503SF output current and power, maintains through-hole mounting, and supports commercial ITE applications. CC3-0503SF-E offers a similar operating temperature range, though package type is 7-DIP vs. 6-DIP, and control features differ.

Frequently Asked Questions (FAQ)

Q1: Which key parameters must be matched for DC DC converter substitution?
A1: Manufacturer, module type, input voltage range, output voltage, maximum output current, isolation voltage, mounting type, output count, and application specification must all be matched or exceeded.

Q2: How does the package difference (6-DIP vs. 7-DIP Module) affect compatibility?
A2: Mechanical fit may vary based on PCB layout and socket requirements. Physical dimensions should be reviewed for direct compatibility with existing footprints.

Q3: Are electrical ratings identical between CCM-0503SF and CC3-0503SF-E?
A3: Both share input voltage range, output voltage, and isolation voltage. CC3-0503SF-E has greater current and power ratings.

Q4: What is the significance of product status in selection?
A4: Selection of an active component (such as CC3-0503SF-E) ensures continued manufacturability and supply, while obsolete models lack ongoing support.

Q5: Is RoHS and REACH compliance important in substitution?
A5: RoHS and REACH status indicate environmental regulatory conformity relevant to many commercial applications. CC3-0503SF-E is listed as RoHS compliant and REACH unaffected.

Q6: Can CC3-0503SF-E be directly substituted for CCM-0503SF in all applications?
A6: Substitution must confirm physical alignment and mounting compatibility, given the change in DIP package specification. Electrical parameters are compatible within listed criteria.
