Engineering Selection Recommendations

PS2801-1-F3-Y-A (Parametric Equivalent - Recommended Primary Choice)

The PS2801-1-F3-Y-A manufactured by Renesas Electronics Corporation is the parametric equivalent for the discontinued PS2801-1-V-F3-A. This part maintains identical electrical specifications including 2500Vrms isolation voltage, 80% to 600% current transfer ratio range, 80V maximum output voltage, and 300mV Vce saturation. The component shares the same operating temperature range (-55°C to 100°C) and switching characteristics (6µs turn-on, 5µs turn-off). Both parts are housed in 4-SOIC packaging with 0.173" width and are ROHS3 compliant. The PS2801-1-F3-Y-A is currently in active production status with 674 pieces available in inventory, providing immediate design continuity for applications previously using the CEL part.

TCMT1106 (Functional Substitute - Enhanced Isolation)

The TCMT1106 manufactured by Vishay Semiconductor Opto Division functions as a substitute for applications where enhanced isolation performance is acceptable. This part provides 3750Vrms isolation voltage, exceeding the 2500Vrms requirement of the original part. The TCMT1106 maintains the same single-channel transistor output configuration, 50mA output current capability, and 300mV Vce saturation. The 4-SOIC package footprint is identical. Key differences include a higher minimum current transfer ratio (100% versus 80%), lower maximum current transfer ratio (300% versus 600%), and slightly reduced maximum output voltage (70V versus 80V). Operating temperature range is -40°C to 100°C, which is narrower at the lower end. Switching times are slower (9.5µs turn-on, 8.5µs turn-off versus 6µs and 5µs). The TCMT1106 is in active production with 4108 pieces in inventory and is ROHS3 compliant.

Selection Criteria:

For direct replacement with identical electrical performance, select PS2801-1-F3-Y-A. For applications requiring higher isolation voltage margins or where the enhanced 3750Vrms rating provides system-level benefits, TCMT1106 is suitable provided the lower maximum output voltage (70V) and slower switching times are compatible with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the PS2801-1-F3-Y-A be used as a direct replacement for the PS2801-1-V-F3-A?

A: Yes. The PS2801-1-F3-Y-A is a parametric equivalent with identical isolation voltage (2500Vrms), current transfer ratio range (80% to 600% @ 5mA), maximum output voltage (80V), output current (50mA), Vce saturation (300mV), operating temperature range (-55°C to 100°C), and switching characteristics. Both parts use 4-SOIC packaging with 0.173" width. Pin configuration and electrical performance are equivalent.

Q: What are the key differences between the PS2801-1-F3-Y-A and TCMT1106?

A: The primary differences are isolation voltage (2500Vrms versus 3750Vrms), current transfer ratio range (80-600% versus 100-300%), maximum output voltage (80V versus 70V), operating temperature range (-55°C to 100°C versus -40°C to 100°C), and switching times (6µs/5µs versus 9.5µs/8.5µs). Both maintain 50mA output current and 300mV Vce saturation. Package footprints are identical.

Q: Is the TCMT1106 compatible with the original PS2801-1-V-F3-A application?

A: Compatibility depends on specific circuit requirements. The TCMT1106 provides higher isolation voltage (3750Vrms), which is beneficial for isolation margin. However, the lower maximum output voltage (70V versus 80V) and slower switching times must be evaluated against circuit design specifications. The narrower operating temperature range (-40°C to 100°C) may be limiting for applications requiring -55°C operation.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The PS2801-1-F3-Y-A and TCMT1106 are both ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited), matching the compliance profile of the original PS2801-1-V-F3-A.

Q: What is the package compatibility between these parts?

A: All three parts (PS2801-1-V-F3-A, PS2801-1-F3-Y-A, and TCMT1106) use 4-SOIC surface mount packaging with 0.173" width (4.40mm). PCB footprints are mechanically compatible.

Q: Which substitute should be selected for new designs?

A: For new designs requiring 2500Vrms isolation with the specified electrical characteristics, the PS2801-1-F3-Y-A is the recommended choice due to parametric equivalence and active production status. The TCMT1106 is suitable for designs where 3750Vrms isolation voltage provides system-level advantages and where the lower maximum output voltage and slower switching times are acceptable.
