PS2501-1-W-A Equivalent & Substitute Parts

Part Overview

The PS2501-1-W-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 industrial control, power management, and signal conditioning systems.

The original PS2501-1-W-A manufactured by CEL is discontinued at DiGi Electronics. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this optoisolator topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2501-1-W-A is determined by strict equivalence across the following critical parameters:

Isolation and Safety Specifications: Isolation voltage must equal 5000Vrms; channel count must equal 1; output configuration must be transistor type.

Electrical Performance: Current transfer ratio range (130% to 260% @ 5mA), rise/fall time (3µs, 5µs), maximum output voltage (80V), maximum output current (50mA), and Vce saturation (300mV) must match exactly.

Physical and Environmental Compatibility: Package type must be 4-DIP (0.300", 7.62mm); mounting type must be through hole; operating temperature range must span -55°C to 100°C.

Regulatory Compliance: RoHS3 compliance and REACH affected status must be maintained.

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

Parameter Comparison

Engineering Selection Recommendations

The PS2501-1-W-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL version. Both parts share identical electrical specifications, package configuration, and regulatory compliance status.

Supply Availability: The Renesas Electronics version maintains active product status with 1020 pieces in stock, compared to the CEL version which is discontinued. This makes the Renesas variant the appropriate selection for new procurement and ongoing production support.

Compliance Continuity: Both versions maintain RoHS3 compliance, REACH affected status, and EAR99 ECCN classification, ensuring regulatory requirements are preserved in system designs.

Physical Compatibility: Identical 4-DIP through-hole package specifications ensure direct PCB compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the Renesas Electronics PS2501-1-W-A replace the CEL PS2501-1-W-A in existing designs?

A: Yes. Both parts are parametrically identical across all electrical specifications, isolation voltage, output characteristics, and package configuration. Direct substitution is supported without circuit modification.

Q: Are there any differences in isolation voltage or safety ratings between these parts?

A: No. Both versions are rated for 5000Vrms isolation voltage and maintain identical electrical performance across current transfer ratio, output voltage, and saturation characteristics.

Q: What is the significance of the 4-DIP package specification?

A: The 4-DIP (0.300", 7.62mm) package is a through-hole configuration with standardized pin spacing. Both substitute parts use this identical package, ensuring mechanical and electrical compatibility with existing PCB designs without layout changes.

Q: Why is the CEL version discontinued?

A: Product discontinuation decisions are made by manufacturers based on market demand and production strategies. The Renesas Electronics equivalent remains in active production and provides equivalent functionality.

Q: Are there any temperature or environmental operating differences?

A: No. Both parts operate across the identical temperature range of -55°C to 100°C and maintain the same moisture sensitivity level (MSL 1 - Unlimited).

Q: What inventory considerations should be evaluated?

A: The Renesas Electronics version has 1020 pieces in stock, providing immediate availability. The CEL version is discontinued. For new designs and production continuity, the Renesas variant is the recommended selection.
