LTV-217-B-V-G Equivalent & Substitute Parts

Part Overview

The LTV-217-B-V-G is a single-channel optoisolator with transistor output manufactured by Lite-On Inc. This component provides 3750Vrms isolation voltage and is designed for DC input applications requiring galvanic isolation in 4-SSOP surface mount packaging. The part is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility permits selection from multiple qualified manufacturers offering equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following critical parameters:

• Isolation voltage: 3750Vrms (mandatory match)
• Number of channels: 1 (mandatory match)
• Output type: Transistor (mandatory match)
• Current transfer ratio range: 130% to 260% @ 5mA (mandatory match)
• Maximum output voltage: 80V (mandatory match)
• Output current: 50mA (mandatory match)
• Operating temperature: -55°C to 110°C (mandatory match)
• Input type: DC (mandatory match)
• Mounting type: Surface Mount (mandatory match)
• RoHS3 compliance: Required

All identified substitute parts meet these criteria. Variations in packaging designation (4-SSOP, 4-SO, 4-SOP) represent equivalent mechanical footprints suitable for the same PCB layout. Minor differences in turn-on/turn-off timing and rise/fall time specifications do not affect substitution eligibility when within the specified operating ranges.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status with full RoHS3 compliance and MSL 1 rating, ensuring compatibility with current manufacturing and environmental standards.

ACPL-217-50BE and ACPL-217-56BE (Broadcom Limited) provide direct electrical equivalence with 4166 and 20300 units in stock respectively, offering the highest inventory availability among Broadcom options.

EL3H7(B)(TA)-VG (Everlight Electronics) delivers superior Vce saturation performance at 200mV maximum compared to 400mV in other options, with 1506 units available.

FODM217BR2 and FODM217BR2V (onsemi) maintain full parameter equivalence with 63284 and 1862 units in stock respectively, representing the highest single-part inventory level.

VOS617A-8X001T (Vishay Semiconductor) provides complete electrical equivalence with 4200 units available, with marginally lower forward voltage (1.18V typical) and extended turn-on/turn-off timing specifications (6µs, 4µs).

Selection should prioritize inventory availability, lead time requirements, and established supplier relationships within your procurement framework.

Frequently Asked Questions (FAQ)

Q: Can ACPL-217-50BE replace LTV-217-B-V-G directly?

A: Yes. Both parts share identical isolation voltage (3750Vrms), current transfer ratio range (130-260% @ 5mA), output specifications (80V max, 50mA), and operating temperature range (-55°C to 110°C). Package designation differs (4-SO vs 4-SSOP) but represents equivalent 4-pin surface mount footprints.

Q: What is the difference between 4-SSOP, 4-SO, and 4-SOP packaging?

A: These designations represent equivalent 4-pin surface mount packages with identical 0.173" (4.40mm) width and pin spacing. All are suitable for the same PCB layout and reflow soldering processes. Designation variations reflect manufacturer nomenclature preferences.

Q: Does EL3H7(B)(TA)-VG offer any performance advantage?

A: EL3H7(B)(TA)-VG specifies maximum Vce saturation of 200mV compared to 400mV in other substitutes. This represents improved saturation performance. Turn-on/turn-off timing data is not provided for this part. All other electrical parameters remain equivalent.

Q: Which substitute has the best inventory availability?

A: FODM217BR2 (onsemi) offers the highest inventory with 63284 units in stock. ACPL-217-56BE (Broadcom) provides 20300 units. Both represent strong availability positions for immediate procurement.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance with MSL 1 (unlimited) moisture sensitivity rating, meeting current environmental and manufacturing standards.

Q: Can I use VOS617A-8X001T if my design requires specific timing characteristics?

A: VOS617A-8X001T specifies turn-on/turn-off timing of 6µs and 4µs respectively, compared to 3µs and 3µs for LTV-217-B-V-G. If your circuit design depends on the faster timing of the original part, verify that the extended timing of the Vishay option remains within your system requirements before substitution.
