Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL750M10CKC is determined by strict equivalence across the following critical parameters:

• Output voltage: 10V fixed
• Maximum output current: 750mA
• Maximum input voltage: 26V
• Dropout voltage: 0.6V @ 750mA
• Package type: TO-220-3 (through-hole mounting)
• Protection features: Over Current, Over Temperature, Over Voltage, Reverse Polarity
• Operating temperature range: 0°C ~ 125°C
• PSRR: 55dB (120Hz)

The TL750M10CKCSE3 meets all these electrical and mechanical specifications while maintaining active product status and full compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The TL750M10CKCSE3 is the direct parametric equivalent for the obsolete TL750M10CKC. Both devices share identical electrical specifications, thermal performance, and protection characteristics. The primary distinction is product status: TL750M10CKCSE3 maintains active production status, ensuring long-term availability and supply chain continuity.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support. The packaging difference (tube versus unspecified for the original) does not affect electrical or mechanical compatibility in through-hole applications.

Frequently Asked Questions (FAQ)

Q: Can TL750M10CKCSE3 be used as a direct replacement for TL750M10CKC?

A: Yes. Both devices are electrically and mechanically identical across all specified parameters: 10V fixed output, 750mA current capacity, 26V maximum input, 0.6V dropout voltage, and TO-220-3 package. The substitute maintains all protection features and operating temperature range.

Q: What is the difference between these two part numbers?

A: The primary difference is product lifecycle status. TL750M10CKC is obsolete, while TL750M10CKCSE3 is active. The suffix "SE3" indicates a packaging variant (tube packaging). Electrical performance and specifications are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications. Regulatory compliance is equivalent.

Q: Is the TO-220-3 package compatible with existing PCB designs?

A: Yes. Both parts use the same TO-220-3 through-hole package, ensuring pin-for-pin compatibility and identical PCB footprint requirements.

Q: What inventory status should I expect?

A: TL750M10CKCSE3 is actively produced and stocked. The original TL750M10CKC, being obsolete, has limited remaining inventory and should not be relied upon for new procurement.
