Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the BA7824CP-E2 are qualified based on the following critical parameters that determine functional equivalence:

• Fixed positive 24V output voltage
• Through-hole TO-220-3 package family
• Positive output configuration
• Linear regulator topology
• ROHS3 compliance
• Maximum input voltage rating of 33V or greater
• Output current capability of 1A or greater
• Operating temperature range that encompasses or exceeds -40°C ~ 85°C

The substitute parts L7824CP and MC7824BTG meet these criteria while maintaining pin-compatible TO-220 package configurations and identical output voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

Both L7824CP and MC7824BTG are active product alternatives to the obsolete BA7824CP-E2. Selection between these substitutes should be based on the following factors:

L7824CP (STMicroelectronics): Offers increased output current capability at 1.5A, providing design margin above the original 1A specification. Suitable for applications where higher current delivery is beneficial. Operating temperature range extends to 125°C maximum.

MC7824BTG (onsemi): Maintains the original 1A output current specification, providing direct functional equivalence. Supports the full temperature range of -40°C ~ 125°C, matching the lower temperature limit of the original device. Both alternatives maintain ROHS3 compliance and identical output voltage regulation.

Both substitute parts are currently in active production status, ensuring long-term availability and supply chain stability compared to the obsolete BA7824CP-E2.

Frequently Asked Questions (FAQ)

Q: Can L7824CP and MC7824BTG be used interchangeably with BA7824CP-E2?

A: Yes, both parts are pin-compatible substitutes with identical 24V fixed output voltage and TO-220-3 package configuration. The primary difference is output current capability: L7824CP provides 1.5A while MC7824BTG provides 1A, matching the original specification.

Q: What is the difference between TO-220-3 Cropped Leads and TO-220-3 Full Pack?

A: Both are TO-220-3 package variants suitable for through-hole mounting. Cropped leads and full pack refer to lead length variations. Pin spacing and electrical performance remain identical, ensuring mechanical and electrical compatibility in standard PCB layouts.

Q: Are the substitute parts ROHS3 compliant?

A: Yes, both L7824CP and MC7824BTG are ROHS3 compliant, matching the compliance status of the original BA7824CP-E2.

Q: What is the significance of product status being "Active" for the substitute parts?

A: Active product status indicates ongoing manufacturing and availability from the respective manufacturers. This ensures reliable component procurement and supply chain continuity, addressing the obsolescence of the original BA7824CP-E2.

Q: Do the substitute parts have the same dropout voltage?

A: Yes, all three parts specify 2V maximum dropout voltage at 1A typical operation, ensuring equivalent voltage regulation performance in circuit applications.
