Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LTV-217-D-G are qualified based on the following criteria:

• Isolation voltage of 3750Vrms
• Single-channel transistor output configuration
• Current transfer ratio range of 300% to 600% @ 5mA
• Maximum output voltage of 80V
• Maximum output current of 50mA per channel
• Vce saturation maximum of 400mV
• Operating temperature range of -55°C to 110°C
• Surface mount package with 4-pin SOIC footprint (0.173", 4.40mm width)
• ROHS3 compliance and MSL 1 rating

All identified substitutes meet these electrical and mechanical parameters, enabling direct functional replacement in applications designed for the LTV-217-D-G.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status with ROHS3 compliance and MSL 1 rating, ensuring regulatory alignment and handling compatibility with the original LTV-217-D-G. The ACPL-217-50DE from Broadcom and FODM217DR2 / FODM217DR2V from onsemi are electrically and mechanically equivalent, with all critical parameters matching the primary device. Selection among these substitutes may be based on supplier availability, lead time, packaging format (Cut Tape & Digi-Reel for ACPL-217-50DE; Tape & Reel for FODM217 variants), or procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can ACPL-217-50DE replace LTV-217-D-G directly? A: Yes. The ACPL-217-50DE meets all electrical parameters including 3750Vrms isolation, 300-600% current transfer ratio, 80V maximum output voltage, and 50mA output current. Both devices use 4-SOIC packaging and operate across -55°C to 110°C. The primary difference is packaging format: ACPL-217-50DE is supplied in Cut Tape & Digi-Reel, while LTV-217-D-G uses standard tape and reel.

Q: What is the difference between FODM217DR2 and FODM217DR2V? A: Both onsemi parts are electrically equivalent to LTV-217-D-G with one exception: FODM217DR2V has a fall time of 3µs (typical) compared to 3µs for FODM217DR2. This minor timing difference does not affect functional compatibility in applications designed for the LTV-217-D-G.

Q: Are all substitutes pin-compatible? A: Yes. All substitute parts use the 4-SOIC package with 0.173" width and 4.40mm dimensions, ensuring mechanical and electrical pin compatibility with the LTV-217-D-G.

Q: Do all substitutes meet the same compliance standards? A: Yes. All listed substitutes are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the original device's regulatory and handling requirements.

Q: Which substitute has the highest inventory availability? A: FODM217DR2 from onsemi has 45,400 pieces in stock, followed by FODM217DR2V with 45,100 pieces. ACPL-217-50DE from Broadcom has 4,400 pieces available.
