Substitute Part Grouping Explanation

Substitution of the PS2801C-1-P-A is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Single-channel configuration (1 channel)
• Isolation voltage rating of 2500Vrms
• Current transfer ratio range: 150% to 300% @ 5mA
• DC input type with transistor output
• Maximum output voltage of 80V
• Maximum output current of 30mA per channel
• Switching time characteristics: 10µs turn-on, 7µs turn-off (typical)
• Rise/fall time: 5µs rise, 7µs fall (typical)
• Vce saturation maximum of 300mV
• Operating temperature range: -55°C to 100°C

Mechanical Equivalence Criteria:

• 4-SOIC package (0.173" width, 4.40mm)
• Surface mount configuration
• 4-SSOP supplier device package

Compliance Equivalence Criteria:

• ROHS3 compliance
• Moisture sensitivity level 1 (unlimited)
• REACH unaffected status

Parts meeting all these parameters are classified as direct parametric equivalents and may be substituted without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

The PS2801C-1-P-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL PS2801C-1-P-A. Both parts share identical electrical specifications, mechanical packaging, and compliance certifications.

Selection Basis:

The Renesas Electronics PS2801C-1-P-A maintains active product status with confirmed inventory availability (6446 pcs), whereas the CEL variant is discontinued. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL Level 1 (unlimited moisture sensitivity).

The electrical parameters are identical across all measured specifications: isolation voltage, current transfer ratio, switching times, output voltage/current ratings, and operating temperature range. The 4-SOIC package and surface mount configuration are identical, ensuring PCB layout compatibility without modification.

For applications currently using the CEL PS2801C-1-P-A, direct substitution with the Renesas Electronics variant is supported by parametric equivalence and compliance alignment.

Frequently Asked Questions (FAQ)

Q: Can the Renesas Electronics PS2801C-1-P-A replace the CEL PS2801C-1-P-A without circuit modification?

A: Yes. Both parts are parametrically equivalent across all electrical specifications, including isolation voltage (2500Vrms), current transfer ratio (150-300% @ 5mA), switching times, output ratings, and operating temperature range. The 4-SOIC package dimensions and surface mount configuration are identical, requiring no PCB layout changes.

Q: What are the critical parameters that define substitution eligibility for this optoisolator?

A: Substitution eligibility is determined by: single-channel configuration, 2500Vrms isolation voltage, 150-300% current transfer ratio @ 5mA, DC input with transistor output, 80V maximum output voltage, 30mA maximum output current, 10µs/7µs turn-on/turn-off times, 4-SOIC package, and -55°C to 100°C operating temperature range.

Q: Are there packaging differences between the CEL and Renesas Electronics versions?

A: No. Both versions use the 4-SOIC package (0.173" width, 4.40mm) with 4-SSOP supplier device package designation. Surface mount configuration and pin assignments are identical.

Q: What is the compliance status of the substitute part?

A: The Renesas Electronics PS2801C-1-P-A is ROHS3 compliant, REACH unaffected, and carries MSL Level 1 (unlimited moisture sensitivity), matching the compliance profile of the original CEL part.

Q: Why is the CEL PS2801C-1-P-A discontinued?

A: Product discontinuation information is not provided in the technical specifications. Discontinuation status is confirmed at DiGi Electronics. The Renesas Electronics equivalent maintains active production status.

Q: Are there inventory considerations when selecting the substitute?

A: The Renesas Electronics PS2801C-1-P-A has confirmed inventory of 6446 pcs in stock, providing supply continuity for production and maintenance applications.
