PS2501L-4-A Equivalent & Substitute Parts

Part Overview

The PS2501L-4-A is a 4-channel optoisolator with transistor output, rated for 5000Vrms isolation voltage. This component is designed for applications requiring galvanic isolation between input and output circuits with moderate current switching capability. The main part (CEL manufacturer) is discontinued at DiGi Electronics, necessitating identification of equivalent alternatives to maintain design continuity and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2501L-4-A is determined by strict equivalence across the following critical parameters:

Isolation and Switching Characteristics:

• Voltage isolation rating of 5000Vrms
• 4-channel configuration
• Transistor output topology
• Current transfer ratio range: 80% to 600% @ 5mA

Electrical Performance:

• Maximum output voltage: 80V
• Output current per channel: 50mA
• Vce saturation: 300mV maximum
• Rise and fall times: 3µs and 5µs respectively

Physical and Environmental Specifications:

• 16-SMD surface mount package with gull wing leads
• Operating temperature range: -55°C to 100°C
• Moisture sensitivity level 1 (unlimited shelf life)
• ROHS3 compliance and REACH applicability

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

Parameter Comparison

Engineering Selection Recommendations

The PS2501L-4-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL PS2501L-4-A. Both parts share identical electrical specifications, package configuration, and compliance certifications.

Compliance and Regulatory Status: Both variants maintain ROHS3 compliance and REACH applicability, satisfying environmental and regulatory requirements for current manufacturing standards. The Renesas variant carries a "Not For New Designs" status, indicating it remains available for existing production but is not recommended for new product development.

Availability and Supply Chain: The CEL variant is discontinued at DiGi Electronics. The Renesas equivalent provides continuity for existing designs requiring the PS2501L-4-A specification. Inventory availability should be verified with authorized distributors prior to procurement.

Packaging and Handling: The Renesas variant is supplied in tube packaging, whereas the CEL variant packaging is unspecified. Both employ identical 16-SMD gull wing surface mount packages with MSL 1 rating, requiring no special moisture control during storage or handling.

Frequently Asked Questions (FAQ)

Q: Can the Renesas PS2501L-4-A replace the discontinued CEL PS2501L-4-A in existing designs?

A: Yes. Both parts are parametrically identical across all specified electrical, thermal, and mechanical characteristics. No circuit modifications are required for substitution.

Q: Are there differences in package handling or storage between the two manufacturers?

A: Both parts carry MSL 1 (Unlimited) moisture sensitivity rating, eliminating special moisture control requirements. The Renesas variant is supplied in tube packaging. Standard surface mount handling procedures apply to both variants.

Q: What is the significance of the "Not For New Designs" status on the Renesas part?

A: This designation indicates the part remains available for production support of existing designs but is not recommended for incorporation into new product development. For new designs, consultation with the manufacturer regarding current-generation alternatives is appropriate.

Q: Are the electrical performance characteristics identical between manufacturers?

A: Yes. Current transfer ratio, isolation voltage, output current, switching times, and all other specified electrical parameters are identical. Both parts meet the same performance envelope.

Q: What compliance certifications apply to both variants?

A: Both the CEL and Renesas PS2501L-4-A variants are ROHS3 compliant and REACH affected. Both carry EAR99 export classification and HTSUS code 8541.49.8000.
