Substitute Part Grouping Explanation

Substitute parts for the PS2501-1-M-A are identified based on strict parametric equivalence. The following criteria determine substitutability:

Critical Parameters for Substitution:

• Isolation voltage: 5000Vrms
• Number of channels: 1
• Output configuration: Transistor output
• Current transfer ratio range: 80% to 240% @ 5mA
• Maximum output voltage: 80V
• Maximum output current: 50mA
• Package type: 4-DIP (0.300", 7.62mm)
• Mounting type: Through Hole
• Operating temperature range: -55°C to 100°C

Parts matching all critical parameters are classified as parametric equivalents and direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

The PS2501-1-M-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL PS2501-1-M-A. Both components share identical electrical specifications, package configuration, and compliance certifications.

Selection Basis:

The Renesas Electronics version maintains active product status, ensuring ongoing availability and supply chain continuity. Both versions comply with ROHS3 and REACH requirements, with identical moisture sensitivity levels and export classifications (ECCN EAR99).

The parametric equivalence across all critical isolation voltage, channel configuration, output characteristics, and thermal specifications supports direct substitution in existing circuit designs without modification to PCB layout or component footprint.

Frequently Asked Questions (FAQ)

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