Substitute Part Grouping Explanation

Substitution of the PS2801-1-L-A is determined by strict equivalence across the following critical parameters:

Isolation Voltage: 2500Vrms isolation rating is the primary functional requirement. Substitute parts must maintain this voltage specification.

Channel Configuration: Single-channel (1 channel) output is mandatory for direct substitution.

Output Type: Transistor output configuration must be preserved.

Electrical Performance: Current transfer ratio range (100% to 300% @ 5mA), switching times (6µs turn-on, 5µs turn-off), and output current capability (50mA per channel) define functional compatibility.

Package Compatibility: 4-SSOP surface mount package with 4.40mm width ensures mechanical and thermal compatibility with existing PCB layouts.

Input Type: DC input specification must be maintained.

Operating Temperature Range: -55°C to 100°C operating range defines environmental suitability.

Substitute parts meeting all these parameters are electrically and mechanically interchangeable with the original PS2801-1-L-A component.

Frequently Asked Questions (FAQ)

Q: Can the Renesas Electronics PS2801-1-L-A directly replace the discontinued CEL PS2801-1-L-A?

A: Yes. Both components are parametrically identical across all critical specifications: 2500Vrms isolation voltage, single-channel transistor output, 50mA output current, 4-SSOP package, and -55°C to 100°C operating temperature range. Electrical performance, switching characteristics, and compliance certifications are equivalent.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution eligibility is determined by: isolation voltage (2500Vrms), number of channels (1), output type (transistor), current transfer ratio range (100% to 300% @ 5mA), switching times (6µs turn-on, 5µs turn-off), maximum output current (50mA), package type (4-SSOP), and operating temperature range (-55°C to 100°C).

Q: Are there any package or pinout differences between the CEL and Renesas versions?

A: No. Both versions use the 4-SSOP package with 4.40mm width (4-SOIC form factor). Pinout and mechanical dimensions are identical, ensuring direct PCB compatibility without layout modifications.

Q: What is the difference between the CEL and Renesas versions?

A: The primary difference is manufacturer and product status. The CEL version is discontinued; the Renesas Electronics version is active with higher inventory availability. All electrical and mechanical specifications are identical.

Q: Are both versions RoHS and REACH compliant?

A: Yes. Both the CEL and Renesas Electronics PS2801-1-L-A are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements.

Q: What packaging format is the Renesas version supplied in?

A: The Renesas Electronics version is supplied in Strip packaging, which is standard for surface mount components and compatible with automated pick-and-place assembly equipment.
