Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AN7715SP are identified based on the following critical parameters that determine functional equivalence:

Output Voltage: Fixed 15V output is the primary functional requirement. Substitute parts must maintain this exact output voltage specification.

Output Current Capability: The AN7715SP provides 1.2A maximum output current. Substitute parts with equal or greater current rating (≥1.2A) are considered functionally equivalent.

Input Voltage Range: Maximum input voltage of 26.5V defines the input operating envelope. Substitute parts must support this voltage range or higher.

Package / Case: TO-252-3 (DPAK) packaging with identical pinout ensures mechanical and electrical compatibility on existing PCBs.

Protection Features: Over-current, over-temperature, and short-circuit protection are standard requirements for this regulator class.

Output Configuration: Positive fixed output topology must be maintained.

The BAJ5CC0FP-E2 meets these substitution criteria with compatible electrical specifications and identical packaging.

Engineering Selection Recommendations

Primary Substitute: BAJ5CC0FP-E2 (Rohm Semiconductor)

The BAJ5CC0FP-E2 is the recommended substitute for the obsolete AN7715SP based on the following engineering criteria:

Product Status: The BAJ5CC0FP-E2 is actively manufactured by Rohm Semiconductor, ensuring long-term availability and supply chain continuity compared to the obsolete AN7715SP.

Regulatory Compliance: The BAJ5CC0FP-E2 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The AN7715SP is RoHS non-compliant, which may restrict use in new designs or regulated markets.

Electrical Compatibility: Both devices provide identical 15V fixed output voltage and TO-252-3 packaging. The BAJ5CC0FP-E2 output current rating of 1.0A is 0.2A lower than the AN7715SP; applications requiring the full 1.2A output must be evaluated against actual circuit current demands.

Enhanced Features: The BAJ5CC0FP-E2 includes over-voltage protection in addition to over-current and over-temperature protection, providing additional circuit safeguarding. Extended operating temperature range (-40°C to 125°C) supports broader environmental applications.

Thermal and Quiescent Performance: The BAJ5CC0FP-E2 draws 2.5 mA quiescent current versus 5 mA for the AN7715SP, reducing standby power consumption by 50%.

Noise Performance: The AN7715SP provides 60dB PSRR at 120Hz compared to 55dB for the BAJ5CC0FP-E2. Applications with stringent noise rejection requirements should evaluate this 5dB difference.

Frequently Asked Questions (FAQ)

Q: Can the BAJ5CC0FP-E2 directly replace the AN7715SP on existing PCBs?

A: Yes. Both devices use identical TO-252-3 (DPAK) packaging with the same pinout. The BAJ5CC0FP-E2 is a direct mechanical and electrical replacement for PCB applications.

Q: What is the significance of the 0.2A output current difference between these parts?

A: The AN7715SP is rated for 1.2A maximum output current, while the BAJ5CC0FP-E2 is rated for 1.0A. If your circuit draws less than 1.0A, both parts are equivalent. If your circuit requires 1.0A to 1.2A, the BAJ5CC0FP-E2 may operate at or near its maximum rating, reducing thermal margin. Verify actual circuit current requirements before substitution.

Q: Why is the input voltage maximum different (26.5V vs 25V)?

A: The AN7715SP accepts input voltages up to 26.5V, while the BAJ5CC0FP-E2 is rated to 25V. For applications with input voltages between 25V and 26.5V, the AN7715SP provides additional headroom. Most standard power supply designs operate well below 25V, making this difference negligible for typical applications.

Q: Does the RoHS compliance difference matter for my application?

A: RoHS3 compliance is mandatory for products sold in the European Union and increasingly required by major OEMs worldwide. The BAJ5CC0FP-E2 meets ROHS3 standards, while the AN7715SP does not. For new designs, regulatory compliance, or supply to regulated markets, the BAJ5CC0FP-E2 is the appropriate choice.

Q: What does the 5dB PSRR difference mean in practical terms?

A: PSRR (Power Supply Rejection Ratio) measures how effectively the regulator rejects noise from the input supply. The AN7715SP's 60dB PSRR is superior to the BAJ5CC0FP-E2's 55dB. For noise-sensitive analog circuits, this difference may be significant. For digital or general-purpose applications, both ratings are typically adequate.

Q: Is the extended temperature range of the BAJ5CC0FP-E2 important?

A: The BAJ5CC0FP-E2 operates from -40°C to 125°C, while the AN7715SP operates from 25°C to 125°C. If your application requires operation below 25°C, the BAJ5CC0FP-E2 is necessary. For room-temperature and elevated-temperature applications, both parts are equivalent.

Q: What inventory considerations should I evaluate?

A: The AN7715SP has 1051 pieces in stock but is obsolete with no future manufacturing. The BAJ5CC0FP-E2 has 2118 pieces in stock and is actively manufactured. For long-term production or maintenance support, the BAJ5CC0FP-E2 ensures sustained availability.
