PS2503L-1-M-A Equivalent & Substitute Parts

Part Overview

The PS2503L-1-M-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 main part (CEL manufacturer) is discontinued at DiGi Electronics, necessitating identification of active equivalent alternatives to maintain supply chain continuity and support ongoing production requirements.

• Output voltage maximum: 40V
• Output current per channel: 30mA
• Vce saturation: 250mV maximum

Switching Characteristics:

• Rise time: 20µs
• Fall time: 30µs
• Input type: DC
• Output type: Transistor

Physical and Environmental Specifications:

• Number of channels: 1
• Mounting type: Surface Mount
• Package type: 4-SMD, Gull Wing
• Operating temperature range: -55°C to 100°C

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

Parameter Comparison

Engineering Selection Recommendations

The PS2503L-1-M-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL version. Both parts share identical electrical specifications, switching characteristics, and physical packaging.

Selection Basis:

The Renesas Electronics version is recommended for new procurement due to active product status and confirmed availability (1111 pcs in stock). The part maintains full compliance with ROHS3 and REACH requirements, matching the regulatory profile of the original component.

Both versions are supplied in 4-SMD, Gull Wing packages with identical pin configurations and electrical performance across the specified operating temperature range of -55°C to 100°C.

The packaging difference (CEL: unspecified; Renesas: Tube) does not affect functional compatibility or circuit performance.

Frequently Asked Questions (FAQ)

Q: Can the Renesas PS2503L-1-M-A directly replace the CEL PS2503L-1-M-A in existing designs?

A: Yes. Both parts are identical in electrical performance, isolation voltage (5000Vrms), current transfer ratio (100-200% @ 1mA), output specifications (40V max, 30mA per channel), and physical package (4-SMD, Gull Wing). No circuit modifications are required.

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

A: Substitution is determined by matching: isolation voltage (5000Vrms), current transfer ratio range (100-200% @ 1mA), output voltage and current ratings (40V, 30mA), Vce saturation (250mV max), switching times (20µs rise, 30µs fall), single-channel configuration, and 4-SMD surface mount package with gull wing leads.

Q: Are there any compliance or regulatory differences between the two versions?

A: No. Both versions are ROHS3 compliant, REACH affected, and classified under ECCN EAR99 with HTSUS code 8541.49.8000. Moisture sensitivity level is identical (MSL 1, Unlimited).

Q: What is the difference in packaging between the two parts?

A: The CEL version packaging is unspecified in available documentation. The Renesas version is supplied in Tube packaging. This difference affects logistics and handling but does not impact electrical performance or circuit compatibility.

Q: Is the Renesas part actively manufactured and available?

A: Yes. The Renesas PS2503L-1-M-A is listed as Active product status with 1111 pcs confirmed in stock, providing supply chain continuity for the discontinued CEL version.
