ACPL-827-56CE Equivalent & Substitute Parts

Part Overview

The ACPL-827-56CE is a 2-channel optoisolator with transistor output manufactured by Broadcom Limited. This component provides 5000Vrms isolation and is designed for applications requiring galvanic isolation between input and output circuits. The part is currently active in production with 4025 units in stock. Substitute parts are identified based on matching electrical specifications, isolation voltage, channel configuration, and package compatibility to ensure functional equivalence in circuit applications.

Substitute Part Grouping Explanation

Substitute parts for the ACPL-827-56CE are qualified based on the following critical parameters:

Isolation Voltage: 5000Vrms (exact match required)
Number of Channels: 2 channels (exact match required)
Output Type: Transistor output (exact match required)
Package Configuration: 8-SMD, Gull Wing surface mount (exact match required)
Current - Output / Channel: 50mA (exact match required)
Vce Saturation (Max): 200mV (exact match required)
Input Type: DC (exact match required)

The substitute parts LTV-827S and LTV-827S-TA1 from Lite-On Inc. meet all critical electrical and mechanical parameters. Differences in Current Transfer Ratio ranges and maximum output voltage do not prevent substitution when the application circuit design accommodates these variations. Both substitute parts maintain the same isolation voltage, channel count, output type, and package form factor.

Engineering Selection Recommendations

Both LTV-827S and LTV-827S-TA1 are active production parts with ROHS3 compliance and REACH unaffected status, matching the regulatory profile of the ACPL-827-56CE. The Lite-On substitutes maintain identical isolation voltage, channel configuration, output type, and package form factor. The extended operating temperature range (-30°C ~ 110°C) of the substitute parts provides additional thermal margin compared to the ACPL-827-56CE (-30°C ~ 100°C).

Selection between LTV-827S and LTV-827S-TA1 depends on packaging requirements: LTV-827S is supplied in Tube packaging, while LTV-827S-TA1 is supplied in Cut Tape and Digi-Reel format. Both parts are functionally equivalent for circuit applications where the maximum output voltage specification of 35V is sufficient for the intended load.

Frequently Asked Questions (FAQ)

Q: Can LTV-827S or LTV-827S-TA1 be used as direct replacements for ACPL-827-56CE?

A: Yes, both Lite-On parts are direct functional substitutes. They share identical isolation voltage (5000Vrms), channel count (2), output type (transistor), package configuration (8-SMD, Gull Wing), output current rating (50mA), and saturation voltage (200mV). Packaging format differs but does not affect electrical performance.

Q: What is the difference between LTV-827S and LTV-827S-TA1?

A: Both parts are electrically identical. The difference is packaging: LTV-827S is supplied in Tube format, while LTV-827S-TA1 is supplied in Cut Tape and Digi-Reel format. Select based on your assembly process requirements.

Q: Why do the substitute parts have a lower maximum output voltage (35V vs 70V)?

A: The Lite-On LTV-827S and LTV-827S-TA1 are rated for 35V maximum output voltage, while the ACPL-827-56CE is rated for 70V. Substitution is valid only if your circuit design operates within the 35V output voltage limit. If your application requires output voltages above 35V, the ACPL-827-56CE must be retained.

Q: Are there any compliance or regulatory differences?

A: No. All three parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity levels (MSL 1 - Unlimited). Regulatory status is equivalent.

Q: What is the inventory status for substitute parts?

A: LTV-827S has 2000 units in stock, and LTV-827S-TA1 has 2200 units in stock. Both are active production parts with established supply availability.
