• Number of Channels: 1
• Output Type: Darlington
• Current Transfer Ratio (Min): 2000% @ 1mA
• Package / Case: 4-SMD, Gull Wing
• Operating Temperature Range: -55°C ~ 100°C
• Voltage - Output (Max): 40V
• Current - Output / Channel: 200mA

Both identified substitutes meet all mandatory electrical and mechanical parameters, ensuring pin-for-pin compatibility and functional equivalence in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: PS2502L-1-K-A (Renesas Electronics Corporation)

The PS2502L-1-K-A manufactured by Renesas Electronics Corporation is the direct equivalent to the discontinued CEL version. Both parts carry identical electrical specifications and package configurations. The Renesas version holds Active product status with higher inventory availability (1431 units), ensuring supply continuity.

Alternative Substitute: PS2562L2-1-K-A (Renesas Electronics Corporation)

The PS2562L2-1-K-A serves as an alternative substitute with identical electrical parameters and package specifications. This part is manufactured by Renesas Electronics Corporation with Active product status and maintains full parametric compatibility (948 units in stock).

Compliance Considerations

All three parts maintain ROHS3 compliance and REACH Affected status. Selection between active substitutes should prioritize availability and lead time based on current inventory levels and supply chain requirements.

Frequently Asked Questions (FAQ)

Q: Can PS2502L-1-K-A (Renesas) directly replace the discontinued CEL PS2502L-1-K-A?

A: Yes. Both parts share identical electrical parameters, isolation voltage ratings (5000Vrms), output characteristics (Darlington, 200mA, 40V max), and 4-SMD Gull Wing packaging. Direct pin-for-pin substitution is supported.

Q: What is the difference between PS2502L-1-K-A and PS2562L2-1-K-A?

A: Both parts are functionally equivalent with matching electrical specifications (5000Vrms isolation, 2000% minimum CTR, 100µs rise/fall times, 200mA output current). The primary difference is the manufacturer base product designation (PS2502 vs PS2562). Both are suitable for direct substitution.

Q: Are the substitute parts compatible with the original circuit design?

A: Yes. The substitutes maintain all critical parameters: isolation voltage (5000Vrms), current transfer ratio (2000% @ 1mA), output voltage limits (40V), saturation voltage (1V), and temperature operating range (-55°C ~ 100°C). Surface mount 4-SMD Gull Wing packaging ensures mechanical and electrical compatibility.

Q: Does the switch to a Renesas substitute affect compliance requirements?

A: No. Both substitute parts maintain ROHS3 compliance and REACH Affected status equivalent to the original CEL part. Environmental and regulatory requirements remain unchanged.

Q: Should I prioritize based on inventory availability?

A: Inventory levels reflect current stock (CEL: 727 units, Renesas PS2502L-1-K-A: 1431 units, Renesas PS2562L2-1-K-A: 948 units). Selection based on availability is appropriate when lead times or procurement timelines are critical factors.
