ACSL-6400-50T Equivalent & Substitute Parts

Part Overview

The ACSL-6400-50T is a Logic Output Optoisolator manufactured by Broadcom Limited, featuring 2500Vrms isolation, 4-channel configuration, and open collector Schottky clamped output. This component is classified as Obsolete, which necessitates identification of active equivalent parts to ensure continued design support and procurement availability. The part operates across a 3V to 5.5V supply range with a 15MBd data rate and 10kV/µs common mode transient immunity, making it suitable for industrial isolation applications requiring high-speed signal transmission.

Substitute Part Grouping Explanation

The ACSL-6400-50T has been identified with one direct substitute: ACSL-6400-50TE. This substitution is valid based on the following critical parameters that remain identical between both parts:

• Number of Channels: 4
• Voltage - Isolation: 2500Vrms
• Common Mode Transient Immunity (Min): 10kV/µs
• Input Type: DC
• Output Type: Open Collector, Schottky Clamped
• Current - Output / Channel: 50 mA
• Data Rate: 15MBd
• Propagation Delay tpLH / tpHL (Max): 100ns, 100ns
• Rise / Fall Time (Typ): 30ns, 12ns
• Voltage - Forward (Vf) (Typ): 1.52V
• Current - DC Forward (If) (Max): 15mA
• Voltage - Supply: 3V ~ 5.5V
• Operating Temperature: -40°C ~ 100°C
• Package / Case: 16-SOIC (0.154", 3.90mm Width)
• Supplier Device Package: 16-SOIC

The primary distinction between these parts is product status and compliance certification, not electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

The ACSL-6400-50TE is the direct equivalent for the obsolete ACSL-6400-50T. All electrical and mechanical parameters are identical, ensuring pin-for-pin and functional compatibility. The ACSL-6400-50TE offers the following advantages:

• Active product status ensures long-term availability and manufacturing support
• ROHS3 compliance meets current environmental and regulatory requirements
• Standardized packaging options (Cut Tape and Digi-Reel) facilitate procurement and assembly workflows
• Identical performance characteristics eliminate the need for circuit redesign or re-qualification

For new designs or production transitions, the ACSL-6400-50TE is the appropriate selection. For existing inventory management of the ACSL-6400-50T, direct substitution with ACSL-6400-50TE is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Can ACSL-6400-50TE be used as a direct replacement for ACSL-6400-50T in existing designs?

A: Yes. All electrical parameters, timing specifications, isolation voltage, output current, and package dimensions are identical. No circuit modifications are required.

Q: What is the difference between ACSL-6400-50T and ACSL-6400-50TE?

A: The primary differences are product status (Obsolete vs. Active), RoHS compliance (non-compliant vs. ROHS3 Compliant), and packaging format. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with the 16-SOIC package?

A: No. Both parts use the identical 16-SOIC (0.154", 3.90mm Width) package. PCB footprints, solder reflow profiles, and assembly processes remain unchanged.

Q: Why is ACSL-6400-50T classified as Obsolete?

A: Product obsolescence is determined by the manufacturer. The ACSL-6400-50TE serves as the active continuation of this product line.

Q: Does the packaging format (Cut Tape vs. standard packaging) affect electrical performance?

A: No. Packaging format affects only procurement and handling logistics. Electrical and mechanical performance is independent of packaging type.
