Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2733-1-V-F3-A is determined by three critical parameter categories:

Electrical Compatibility: Isolation voltage (2500Vrms), output type (Darlington), and voltage/current ratings must remain unchanged or exceed the original specifications.

Package Compatibility: The 4-SMD, Gull Wing package is the primary consideration. Parts in alternative packages (4-SSOP) represent functional equivalents but require PCB layout modifications.

Performance Parameters: The Current Transfer Ratio minimum of 1500% @ 1mA and rise/fall time of 100µs, 100µs are core performance characteristics that define the substitution class.

Qualifying substitute parts maintain identical isolation voltage, output type, and thermal operating range. Parts within the PS2733 series with identical electrical characteristics but different packaging variants (PS2733-1-F3-A) are classified as parametric equivalents. Parts from the PS2833 series represent functional alternatives, as they differ in Current Transfer Ratio (400%-4500% range) and output current ratings (60mA versus 150mA).

Parameter Comparison

Engineering Selection Recommendations

PS2733-1-F3-A serves as the direct parametric equivalent when Tape & Reel packaging is acceptable. This part maintains identical electrical specifications and package form factor, differing only in the packaging delivery method (Tape & Reel versus standard packaging). Both parts are active in production and ROHS3 compliant.

PS2833-1-V-A and PS2833-1-V-F3-A represent functional alternatives when output current requirements can be reduced from 150mA to 60mA and faster switching speeds (20µs, 5µs rise/fall time) are acceptable. The Current Transfer Ratio range (400%-4500%) is broader than the PS2733 series (1500% fixed), providing greater operating margin in certain applications. These parts utilize 4-SSOP packaging, requiring printed circuit board layout modifications. Both alternatives are active and ROHS3 compliant.

Selection should prioritize active production status parts and compliance certifications. Where package pin-out compatibility is critical, PS2733-1-F3-A ensures drop-in replacement without layout redesign.

Frequently Asked Questions (FAQ)

Q: Can PS2833-1-V-A replace PS2733-1-V-F3-A directly on the circuit board?

A: No. The PS2833 series uses 4-SSOP packaging instead of 4-SMD Gull Wing, requiring PCB footprint and trace layout modifications.

Q: What is the primary difference between PS2733-1-F3-A and PS2733-1-V-F3-A?

A: Both parts maintain identical electrical and mechanical specifications. The difference is packaging format: PS2733-1-F3-A uses Tape & Reel delivery, while PS2733-1-V-F3-A uses standard packaging.

Q: Are PS2833 parts suitable if the application requires 150mA output current?

A: No. PS2833 parts are rated for 60mA maximum output current per channel, which is insufficient for designs requiring 150mA.

Q: What compliance certifications apply to all substitute parts listed?

A: All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control. All carry MSL 1 (Unlimited) moisture sensitivity designation.

Q: Can switching speed differences affect compatibility?

A: Yes. PS2733 parts specify 100µs rise/fall time, while PS2833 parts specify 20µs, 5µs. Applications with timing-critical circuits may require design validation when switching to PS2833 alternatives.
