Substitute Part Grouping Explanation

Substitution eligibility for the VOS627A-2T is determined by strict equivalence across the following critical parameters:

• Voltage isolation rating: 3750Vrms
• Number of channels: 1
• Output configuration: Transistor output
• Current transfer ratio range: 63% to 125% @ 5mA
• Maximum output voltage: 80V
• Maximum output current per channel: 50mA
• Vce saturation: 400mV maximum
• Operating temperature range: -55°C to 110°C
• Package type: 4-SOIC (4.40mm width)
• Mounting type: Surface Mount
• Manufacturer: Vishay Semiconductor Opto Division
• Product status: Active

Parts meeting all these criteria are classified as parametric equivalents and direct substitutes within the VOS627 base product family.

Parameter Comparison

Engineering Selection Recommendations

Both the VOS627A-2T and VOS627A-2X001T maintain identical electrical and mechanical specifications. Selection between these parts is based on availability and supply chain requirements. Both components are active products with ROHS3 compliance and MSL Level 1 rating, indicating no moisture sensitivity constraints during storage and handling. The VOS627A-2T currently maintains higher inventory levels (45200 Pcs) compared to VOS627A-2X001T (12880 Pcs), which may influence procurement decisions based on lead time and volume requirements.

Frequently Asked Questions (FAQ)

Q: Can VOS627A-2X001T be used as a direct replacement for VOS627A-2T?

A: Yes. Both parts are parametric equivalents with identical electrical characteristics, isolation voltage, output specifications, and package configuration. No circuit modifications are required for substitution.

Q: Are there any differences in the 4-SSOP package between these parts?

A: No. Both parts use the same 4-SOIC package with 0.173" width and 4.40mm dimensions. PCB footprints and assembly processes are identical.

Q: What determines substitution eligibility for optoisolators in this family?

A: Substitution requires matching isolation voltage (3750Vrms), channel count (1), output type (transistor), current transfer ratio range (63-125% @ 5mA), maximum output voltage (80V), maximum output current (50mA), saturation voltage (400mV), operating temperature range (-55°C to 110°C), and package type (4-SOIC surface mount).

Q: Are both parts RoHS compliant?

A: Yes. Both VOS627A-2T and VOS627A-2X001T are ROHS3 compliant with MSL Level 1 rating.

Q: Which part should be selected based on availability?

A: Selection should be based on procurement lead time and volume requirements. VOS627A-2T has higher current inventory (45200 Pcs), while VOS627A-2X001T has lower inventory (12880 Pcs). Both are active products with no discontinuation risk.
