Engineering Selection Recommendations
Both VOL617A-3T and VOL617A-3X001T are active production parts that satisfy all critical electrical and mechanical parameters of the TLP785(GRL-TP6,F. Both substitute parts carry ROHS3 compliance certification. VOL617A-3X001T offers higher inventory availability (35400 units) compared to VOL617A-3T (1637 units) and carries explicit REACH Unaffected status. Selection between these substitutes should be based on packaging requirements: VOL617A-3T is supplied in Tape & Reel format, while VOL617A-3X001T is available in Cut Tape and Digi-Reel® formats.
Frequently Asked Questions (FAQ)
Q: What makes VOL617A-3T and VOL617A-3X001T suitable substitutes for TLP785(GRL-TP6,F?
A: Both parts maintain identical isolation voltage (5000Vrms), channel count (1), current transfer ratio range (100-200% @ 5mA), output voltage rating (80V), output current (50mA), saturation voltage (400mV), and operating temperature range (-55°C ~ 110°C). All three parts use 4-SMD surface mount packages with gull wing leads and MSL 1 rating.
Q: Are there differences in switching performance between the main part and substitutes?
A: The TLP785(GRL-TP6,F specifies Turn On / Turn Off Time of 3µs / 3µs and Rise / Fall Time of 2µs / 3µs. The Vishay substitutes specify 6µs / 5.5µs and 4.6µs / 5µs respectively. These differences remain within acceptable operational margins for optoisolator applications in this category.
Q: What is the difference between VOL617A-3T and VOL617A-3X001T?
A: Both parts are electrically and mechanically identical. The primary differences are packaging format (Tape & Reel versus Cut Tape & Digi-Reel®) and inventory availability. VOL617A-3X001T carries explicit REACH Unaffected status, while VOL617A-3T shows Vendor Undefined REACH status.
Q: Can these substitutes be used in existing PCB designs without modification?
A: Yes. All three parts share identical 4-SMD gull wing package geometry and pin configuration, enabling direct substitution on existing printed circuit boards without layout changes.
Q: What compliance certifications apply to the substitute parts?
A: Both VOL617A-3T and VOL617A-3X001T are ROHS3 compliant. VOL617A-3X001T additionally carries REACH Unaffected status. Both parts carry ECCN EAR99 and HTSUS 8541.49.8000 classifications.
