Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PS2502L-4-A is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Channels: 4
• Voltage - Isolation: 5000Vrms
• Current Transfer Ratio (Min): 200% @ 1mA
• Output Type: Darlington
• Voltage - Output (Max): 40V
• Current - Output / Channel: 160mA
• Rise / Fall Time (Typ): 100µs, 100µs
• Vce Saturation (Max): 1V
• Operating Temperature: -55°C ~ 100°C
• Package / Case: 16-SMD, Gull Wing
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

The PS2502L-4-A manufactured by Renesas Electronics Corporation meets all mandatory parameters and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The PS2502L-4-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the CEL version. Both parts share identical electrical specifications, mechanical packaging, and compliance certifications (ROHS3, REACH, EAR99).

Selection Basis:

• Both versions maintain full parameter equivalence across all critical isolation, output, and thermal specifications
• Both comply with ROHS3 and REACH regulatory requirements
• Both are rated for identical operating temperature ranges and isolation voltages
• Packaging format (16-SMD, Gull Wing) is identical, ensuring PCB layout compatibility
• Moisture sensitivity level (MSL 1) is equivalent, requiring no additional handling precautions

The Renesas version carries a "Not For New Designs" status, indicating it remains available but is not recommended for new product development. The CEL version is discontinued, making the Renesas equivalent the appropriate substitution path for existing designs requiring component replacement or supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the Renesas PS2502L-4-A directly replace the CEL PS2502L-4-A in existing designs?

A: Yes. Both parts are parametrically identical across all electrical, thermal, and mechanical specifications. No circuit modifications are required. PCB footprint compatibility is confirmed through identical 16-SMD, Gull Wing packaging.

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

A: Substitution requires matching: 4-channel configuration, 5000Vrms isolation voltage, 200% minimum current transfer ratio, Darlington output type, 40V maximum output voltage, 160mA per-channel output current, 100µs rise/fall times, 1V maximum Vce saturation, -55°C to 100°C operating range, and 16-SMD Gull Wing surface mount package.

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

A: The component package and case format (16-SMD, Gull Wing) are identical. The Renesas version is supplied in Tube packaging, while the CEL version packaging specification was not provided. This does not affect electrical or mechanical compatibility.

Q: Do both versions meet the same regulatory and compliance standards?

A: Yes. Both the CEL and Renesas PS2502L-4-A versions are ROHS3 compliant, REACH affected, and classified under ECCN EAR99 with HTSUS code 8541.49.8000.

Q: What is the moisture sensitivity level for this component?

A: Both versions are rated MSL 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.

Q: Why is the Renesas version marked "Not For New Designs"?

A: This status indicates the part remains available for replacement and repair applications but is not recommended for new product development. For existing designs requiring component substitution, the Renesas version remains a valid equivalent.
