PS2501L-1-F3-H-A Equivalent & Substitute Parts

Part Overview

The PS2501L-1-F3-H-A is a single-channel optoisolator with transistor output, rated for 5000Vrms isolation voltage. This component is designed for applications requiring galvanic isolation between input and output circuits in surface-mount configurations. The original manufacturer CEL has discontinued this part at DiGi Electronics, necessitating identification of functionally equivalent alternatives to maintain supply chain continuity and support ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2501L-1-F3-H-A is determined by strict equivalence across the following critical parameters:

Isolation and Electrical Performance:

• Voltage isolation rating of 5000Vrms
• Single-channel configuration
• Transistor output topology
• Current transfer ratio range: 80% to 160% @ 5mA
• Maximum output voltage of 80V
• Maximum output current of 50mA per channel

Timing and Input Characteristics:

• Rise/fall time specifications of 3µs and 5µs
• DC input type
• Forward voltage (Vf) of 1.17V typical
• Maximum forward current (If) of 80 mA
• Vce saturation maximum of 300mV

Physical and Environmental Requirements:

• 4-SMD, Gull Wing package configuration
• Surface mount mounting type
• Operating temperature range of -55°C to 100°C
• ROHS3 compliance
• MSL rating of 1 (Unlimited)

Parts meeting all these parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The PS2501L-1-F3-H-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL version. Both parts share identical electrical specifications, isolation ratings, timing characteristics, and package configurations.

Selection Basis:

The Renesas Electronics version is recommended for new procurement due to its active product status. The CEL variant, while currently in stock (924 units), carries discontinued status at DiGi Electronics, indicating limited future availability.

Both versions maintain ROHS3 compliance and identical MSL ratings, ensuring compatibility with standard manufacturing and storage protocols. The Renesas version is supplied in Cut Tape (CT) packaging format, which is standard for production environments.

Electrical performance is identical across all specified parameters, including isolation voltage, current transfer ratio, output voltage and current ratings, and operating temperature range. No circuit redesign or board layout modifications are required when transitioning between these two manufacturers.

Frequently Asked Questions (FAQ)

Q: Can the Renesas Electronics PS2501L-1-F3-H-A be used as a direct replacement for the CEL version?

A: Yes. Both parts are parametrically identical across all specified electrical, mechanical, and environmental parameters. No circuit modifications are required.

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

A: Substitution is determined by matching: 5000Vrms isolation voltage, single-channel configuration, transistor output type, 80-160% current transfer ratio @ 5mA, 80V maximum output voltage, 50mA maximum output current, 3µs/5µs rise/fall times, 1.17V forward voltage, 300mV Vce saturation, 4-SMD Gull Wing package, and -55°C to 100°C operating temperature range.

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

A: The Renesas version is supplied in Cut Tape (CT) format. The CEL version packaging format is not specified in the available data. Both use identical 4-SMD, Gull Wing package configurations suitable for surface mount assembly.

Q: Do both versions meet the same compliance standards?

A: Yes. Both the CEL and Renesas Electronics versions are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage requirements.

Q: Why is the CEL version discontinued if it is still in stock?

A: Discontinuation at DiGi Electronics indicates the manufacturer or distributor has ended active production and support. Existing inventory may remain available through current stock, but future replenishment is not guaranteed. The Renesas version maintains active product status with higher inventory levels (3150 units).
