BA17824CP-E2 Equivalent & Substitute Parts

Part Overview

The BA17824CP-E2 is a linear voltage regulator IC manufactured by Rohm Semiconductor, designed to provide a fixed positive 24V output at 1A current capacity. This through-hole component operates across an industrial temperature range of -40°C to 85°C and is housed in a TO-220-3 package with cropped leads. The device is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameters of this power management category, particularly when the main part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA17824CP-E2 is determined by the following critical parameters:

• Fixed output voltage of 24V
• Through-hole mounting configuration
• TO-220 package family compatibility
• Output current capability of 1A or greater
• Input voltage maximum rating of 33V or higher
• Operating temperature range that encompasses or exceeds -40°C to 85°C
• ROHS3 compliance status
• Positive fixed output configuration

The L7824CP from STMicroelectronics meets these substitution criteria with enhanced specifications in several areas, making it a direct functional equivalent for the BA17824CP-E2.

Engineering Selection Recommendations

The L7824CP is a qualified substitute for the BA17824CP-E2 based on the following engineering criteria:

Both devices maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for equivalent component selection. The L7824CP provides superior electrical specifications with higher output current capacity (1.5A versus 1A), increased maximum input voltage rating (40V versus 33V), and extended operating temperature range (0°C to 125°C versus -40°C to 85°C). The addition of over-temperature and short-circuit protection features in the L7824CP provides enhanced reliability without compromising functional compatibility.

The TO-220-3 package family ensures mechanical and thermal compatibility, with both cropped and full-pack variants suitable for standard through-hole PCB mounting. The identical fixed output voltage of 24V and matching dropout voltage characteristics ensure direct functional equivalence in linear regulation applications.

Frequently Asked Questions (FAQ)

Q: Can the L7824CP directly replace the BA17824CP-E2 in existing designs?

A: Yes. Both devices provide identical 24V fixed output voltage, matching dropout voltage characteristics, and compatible TO-220-3 through-hole mounting. The L7824CP's higher current rating (1.5A) and enhanced protection features make it functionally equivalent and suitable for direct substitution.

Q: What is the difference between TO-220CP-3 (cropped leads) and TO-220FP (full pack)?

A: Both are TO-220-3 package variants suitable for through-hole mounting. The cropped leads variant (CP) has trimmed lead lengths, while the full pack variant (FP) retains standard lead dimensions. Both are mechanically compatible with standard TO-220-3 footprints on PCBs.

Q: Does the higher quiescent current of the L7824CP (8 mA versus 4.5 mA) affect circuit performance?

A: The quiescent current difference of 4.6 mA is acceptable for most linear regulator applications and does not compromise functional compatibility. This variance is within normal manufacturing tolerances for this component category.

Q: Are there any temperature range limitations when substituting the L7824CP?

A: The L7824CP operates across 0°C to 125°C, which encompasses the BA17824CP-E2 operating range of -40°C to 85°C. For applications requiring operation below 0°C, the BA17824CP-E2 remains the specified choice.

Q: What protection features does the L7824CP provide that the BA17824CP-E2 does not?

A: The L7824CP includes over-temperature and short-circuit protection. These features enhance device reliability and circuit protection without affecting the core linear regulation function.
