Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the VOS617A-X001T are grouped based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Voltage - Isolation: 3750Vrms (mandatory)
• Number of Channels: 1 (mandatory)
• Input Type: DC (mandatory)
• Output Type: Transistor (mandatory)
• Voltage - Output (Max): 80V (mandatory)
• Current - Output / Channel: 50mA (mandatory)
• Operating Temperature: -55°C ~ 110°C (mandatory)
• Package / Case: 4-SOIC (0.173", 4.40mm Width) (mandatory)
• Mounting Type: Surface Mount (mandatory)

Secondary Performance Parameters:

• Current Transfer Ratio range
• Vce Saturation voltage
• Turn On / Turn Off Time
• Rise / Fall Time
• Voltage - Forward (Vf)

All identified substitutes meet the mandatory criteria. Variations in secondary parameters reflect different manufacturer specifications and performance grades within the same functional class.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with ROHS3 compliance and MSL Level 1 rating, matching the environmental and regulatory status of the VOS617A-X001T.

Direct Parametric Equivalents (Identical CTR and Vce Sat):

• VOS617AT (Vishay) — Same manufacturer, identical electrical specifications
• ACPL-217-500E and ACPL-217-560E (Broadcom) — Identical CTR range and Vce saturation
• LTV-217-G (Lite-On) — Identical CTR range and Vce saturation

Performance Grade Variants (Tighter CTR specifications):

• EL3H7(EA)-VG (Everlight) — Maintains 50-600% CTR range with lower Vce saturation (200mV vs 400mV)
• EL3H7(TA)-VG (Everlight) — Maintains 50-600% CTR range with lower Vce saturation (200mV vs 400mV)

Higher CTR Grade Variants (Narrower CTR specifications):

• EL3H7(A)(EA)-G, EL3H7(A)-G (Everlight) — 80-160% CTR range, lower Vce saturation
• EL3H7(B)(TA)-VG, EL3H7(B)-G (Everlight) — 130-260% CTR range, lower Vce saturation

Selection should be based on application requirements for current transfer ratio tolerance and saturation voltage performance. All parts support the same operating temperature range and isolation voltage specification.

Frequently Asked Questions (FAQ)

Q: Can I substitute VOS617A-X001T with any of the listed parts?

A: Yes, all listed parts meet the mandatory electrical and mechanical specifications: 3750Vrms isolation, single channel, DC input, transistor output, 50mA output current, 80V maximum output voltage, and 4-SOIC surface mount package. Differences exist in current transfer ratio grades and Vce saturation voltage performance.

Q: What is the difference between the Everlight EL3H7 variants?

A: Everlight offers multiple CTR grades within the EL3H7 family. The (A) grade provides 80-160% CTR, while the (B) grade provides 130-260% CTR. Suffix designations (EA), (TA), (B)(TA) indicate packaging and tape configuration options. All variants maintain 200mV Vce saturation, lower than the VOS617A-X001T specification of 400mV.

Q: Are packaging differences significant for substitution?

A: Packaging format (Tape & Reel, Tube, Cut Tape & Digi-Reel) affects handling and assembly processes but does not impact electrical performance. The 4-SOIC package footprint and pin configuration remain identical across all substitutes, ensuring PCB compatibility.

Q: Which substitute offers the best inventory availability?

A: ACPL-217-560E (Broadcom) has the highest inventory at 42,300 units, followed by ACPL-217-500E at 22,189 units and EL3H7(TA)-VG (Everlight) at 29,910 units.

Q: Do all substitutes have the same compliance certifications?

A: All listed substitutes are ROHS3 compliant with MSL Level 1 rating. REACH status varies by manufacturer but does not affect functional equivalence for this product category.

Q: What is the significance of lower Vce saturation in Everlight parts?

A: Lower Vce saturation (200mV vs 400mV) indicates reduced voltage drop across the transistor output stage, resulting in lower power dissipation and improved efficiency in the output circuit. This is a performance advantage when saturation voltage is a design constraint.
