FOD8163SD Equivalent & Substitute Parts

Part Overview

The FOD8163SD is a logic output optoisolator with Darlington configuration manufactured by onsemi, providing 5000Vrms isolation across a single channel in a 4-SMD surface mount package. This component is classified as obsolete, making equivalent substitutes necessary for ongoing design support and production continuity. The part delivers 80mA output current with typical rise and fall times of 60µs and 53µs respectively, suitable for AC and DC input applications requiring galvanic isolation.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the FOD8163SD is determined by strict alignment of the following critical parameters:

Direct Substitutes (Functionally Equivalent):

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Darlington
• Current - Output / Channel: 80mA
• Rise / Fall Time (Typ): 60µs, 53µs
• Input Type: AC, DC
• Package / Case: 4-SMD, Gull Wing
• Operating Temperature Range: -30°C ~ 100°C

The LTV-8141S, LTV-8141S-TA, and LTV-8141S-TA1 meet all these criteria and are classified as direct substitutes. These parts differ only in packaging format (Tube versus Tape & Reel) and product status (Active versus Obsolete), with no functional or electrical differences.

Similar Substitute (Output Type Variation):

• The LTV-816S shares the same isolation voltage (5000Vrms), channel count (1), package (4-SMD, Gull Wing), and input type (DC). However, it features a Transistor output instead of Darlington, resulting in different electrical characteristics including lower current transfer ratio, faster switching times (4µs, 3µs), higher maximum output voltage (80V), and lower output current (50mA). This part is suitable only when Transistor output characteristics are acceptable for the application.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Select LTV-8141S-TA1 as the primary substitute. This part maintains active product status with the highest available inventory (45,342 pcs), ensuring supply continuity. It is ROHS3 compliant and carries identical electrical specifications to the FOD8163SD. The Tape & Reel packaging format is standard for production environments.

Alternative Direct Replacements: LTV-8141S-TA and LTV-8141S are functionally equivalent alternatives. LTV-8141S-TA offers moderate inventory availability (1,117 pcs) in Tape & Reel format. LTV-8141S provides Tube packaging with 9,389 pcs in stock, suitable for lower-volume applications or manual assembly processes.

For Output Type Variation: LTV-816S is applicable only when Transistor output characteristics are required. This part features faster switching performance (4µs, 3µs rise/fall times) and higher maximum output voltage (80V), but delivers lower output current (50mA) and accepts DC input only. Extended operating temperature range (-50°C ~ 110°C) provides additional thermal margin. Selection requires confirmation that Transistor output topology is compatible with the circuit design.

Frequently Asked Questions (FAQ)

Q: Can LTV-8141S-TA1 be used as a direct replacement for FOD8163SD? A: Yes. LTV-8141S-TA1 is a direct substitute with identical isolation voltage (5000Vrms), output type (Darlington), channel count (1), output current (80mA), rise/fall times (60µs, 53µs), and operating temperature range (-30°C ~ 100°C). The only difference is product status (Active versus Obsolete) and packaging format (Tape & Reel).

Q: What is the difference between LTV-8141S, LTV-8141S-TA, and LTV-8141S-TA1? A: These three parts are electrically identical. LTV-8141S is supplied in Tube packaging. LTV-8141S-TA and LTV-8141S-TA1 are supplied in Tape & Reel format. Selection depends on assembly process requirements and inventory availability.

Q: Can LTV-816S replace FOD8163SD? A: LTV-816S is not a direct replacement. While it shares the same isolation voltage (5000Vrms), package (4-SMD, Gull Wing), and channel count (1), it features Transistor output instead of Darlington. This results in lower output current (50mA versus 80mA), faster switching times (4µs, 3µs versus 60µs, 53µs), and DC-only input capability. Use LTV-816S only if the circuit design specifically requires Transistor output characteristics.

Q: What is the significance of the Tape & Reel packaging designation? A: Tape & Reel (TR) packaging is the standard format for automated surface mount assembly. Tube packaging is used for manual assembly or lower-volume applications. Both formats contain identical components; packaging selection depends on production methodology.

Q: Are all substitute parts RoHS compliant? A: Yes. LTV-8141S, LTV-8141S-TA, LTV-8141S-TA1, and LTV-816S are all ROHS3 compliant. The original FOD8163SD RoHS status is not specified in available documentation.

Q: Which substitute part offers the best supply availability? A: LTV-8141S-TA1 provides the highest inventory level at 45,342 pcs, ensuring reliable supply for production requirements.
