Engineering Selection Recommendations

Parametric Equivalent (Direct Replacement): AL3065S16-13 is a parametric equivalent to AL3065AS16-13, offering identical electrical specifications and the same 16-SOIC package. Both parts are obsolete but maintain full compatibility. AL3065S16-13 has higher inventory availability (45,300 units) compared to AL3065AS16-13 (2,089 units), making it the preferred choice for immediate sourcing needs.

Active Alternatives for New Designs: For applications requiring active product status and extended component lifecycle, LP8860NQVFPRQ1 (Texas Instruments) is the primary recommendation. This part maintains 4-output boost topology, PWM dimming, and exceeds the original supply voltage range (3V to 48V). It carries AEC-Q100 automotive qualification and operates across -40°C to 125°C, providing superior thermal performance. The 32-PowerLQFP package requires PCB layout redesign but offers higher integration density.

MP3398BGF (Monolithic Power Systems) provides an alternative with both analog and PWM dimming capability, matching the original AL3065AS16-13 dimming feature set. This part delivers 350mA per channel output current, exceeding the original 250mA specification, and operates at -40°C to 125°C. The 16-TSSOP-EP package maintains similar footprint characteristics to the original 16-SOIC, reducing layout redesign effort.

MP3394SGF (Monolithic Power Systems) offers PWM-only dimming with 180mA per channel output current. This part is suitable for applications where analog dimming is not required and provides active product status with extended temperature range (-40°C to 125°C).

BD6066EKN-E2 (Rohm Semiconductor) is classified as "Not For New Designs" and carries reduced output current capability (30mA per channel). This part is not recommended for new applications but may serve as a temporary solution for legacy system maintenance where supply voltage is limited to 2.7V to 22V.

Frequently Asked Questions (FAQ)

Q: Can AL3065S16-13 be used as a direct replacement for AL3065AS16-13? A: Yes. AL3065S16-13 is a parametric equivalent with identical electrical specifications, operating temperature range, and 16-SOIC package. Both parts are obsolete, but AL3065S16-13 has significantly higher inventory availability.

Q: What is the primary difference between LP8860NQVFPRQ1 and the original AL3065AS16-13? A: LP8860NQVFPRQ1 is an active product with extended supply voltage range (3V to 48V versus 4.5V to 33V), higher operating temperature ceiling (125°C versus 85°C), and AEC-Q100 automotive qualification. The package changes from 16-SOIC to 32-PowerLQFP, requiring PCB redesign. Output current per channel is 150mA versus the original 250mA.

Q: Does MP3398BGF support analog dimming like the original part? A: Yes. MP3398BGF supports both analog and PWM dimming, matching the original AL3065AS16-13 dimming capability. It delivers 350mA per channel output current and operates at -40°C to 125°C with active product status.

Q: Why does BD6066EKN-E2 have lower output current (30mA) than the original part (250mA)? A: BD6066EKN-E2 is designed for lower-power backlight applications and is classified as "Not For New Designs." It is not recommended as a primary substitute due to insufficient output current capacity for most applications requiring the original AL3065AS16-13 specifications.

Q: What package considerations apply when switching from AL3065AS16-13 to MP3394SGF or MP3398BGF? A: Both MP3394SGF and MP3398BGF use 16-TSSOP-EP packages, which differ from the original 16-SOIC package. While both are 16-pin surface mount packages, pin pitch and footprint dimensions vary. PCB layout modifications are required, but the transition is less extensive than switching to larger packages like the 32-PowerLQFP used by LP8860NQVFPRQ1.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All substitute parts listed (AL3065S16-13, BD6066EKN-E2, LP8860NQVFPRQ1, MP3394SGF, MP3397EF-LF, and MP3398BGF) are ROHS3 compliant, maintaining environmental and regulatory compatibility with the original AL3065AS16-13.

Q: Which substitute part offers the best long-term availability? A: LP8860NQVFPRQ1 (Texas Instruments) is the recommended choice for long-term availability. It carries active product status, AEC-Q100 automotive qualification, and has the highest inventory level (87,000 units). This part is suitable for new designs requiring extended component lifecycle support.
