Engineering Selection Recommendations

ACPL-827-56BE (Broadcom Limited):

Primary choice when maximum output voltage of 70V is required
Suitable for applications with output voltage requirements exceeding 35V
Active product status with established supply chain
ROHS3 compliant and REACH unaffected

LTV-827S (Lite-On Inc.):

Substitute option with 35V maximum output voltage
Tube packaging format
Extended operating temperature range to 110°C
Active product status with higher inventory availability (2000 units)
ROHS3 compliant and REACH unaffected

LTV-827S-TA1 (Lite-On Inc.):

Substitute option with 35V maximum output voltage
Cut Tape (CT) & Digi-Reel® packaging format
Extended operating temperature range to 110°C
Active product status with highest inventory availability (2200 units)
ROHS3 compliant and REACH unaffected

Selection between LTV-827S and LTV-827S-TA1 is determined by packaging and supply chain requirements. Both parts are electrically and mechanically equivalent.

Frequently Asked Questions (FAQ)

Q: Can LTV-827S or LTV-827S-TA1 replace ACPL-827-56BE in all applications?

A: Substitution is valid when the application output voltage requirement does not exceed 35V. The ACPL-827-56BE supports 70V maximum output voltage, while both Lite-On substitutes support 35V maximum. Verify circuit design specifications before substitution.

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

A: Both parts are electrically identical. The difference is packaging format: LTV-827S is supplied in Tube packaging, while LTV-827S-TA1 is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on assembly line requirements and inventory management practices.

Q: Are the Current Transfer Ratio ranges different between the main part and substitutes?

A: Yes. ACPL-827-56BE specifies 130% to 260% @ 5mA, while LTV-827S and LTV-827S-TA1 specify 50% to 600% @ 5mA. Both ranges encompass the typical operating point. Circuit design must account for the wider tolerance range of the substitute parts.

Q: Do the substitute parts support the same operating temperature range?

A: The ACPL-827-56BE operates from -30°C to 100°C. Both LTV-827S and LTV-827S-TA1 operate from -30°C to 110°C, providing extended high-temperature capability.

Q: Are all parts RoHS3 compliant?

A: Yes. ACPL-827-56BE, LTV-827S, and LTV-827S-TA1 are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level.

Q: What packaging options are available?

A: ACPL-827-56BE is supplied in Tape & Reel (TR). LTV-827S is supplied in Tube. LTV-827S-TA1 is supplied in Cut Tape (CT) & Digi-Reel®. Packaging selection affects handling, storage, and assembly processes.
