Substitute Part Grouping Explanation

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

Critical Parameters for Substitution:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Transistor
• Current Transfer Ratio: 80% (Min) @ 5mA and 160% (Max) @ 5mA
• Voltage - Output (Max): 80V
• Current - Output / Channel: 50mA
• Vce Saturation (Max): 300mV
• Package / Case: 4-DIP (0.300", 7.62mm)
• Operating Temperature Range: -55°C ~ 100°C

All substitute parts must match these parameters exactly. Deviations in isolation voltage, channel count, output current rating, or package configuration disqualify a part from substitution.

Parameter Comparison

Engineering Selection Recommendations

The PS2501-1-H-A manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL PS2501-1-H-A. Both parts share identical electrical specifications, isolation ratings, and package configurations.

Selection Basis:

The Renesas Electronics version maintains active product status, ensuring ongoing availability and supply chain continuity. Both versions comply with ROHS3 standards and carry REACH compliance designations, meeting regulatory requirements for industrial and commercial applications.

The parametric equivalence across all critical electrical parameters—isolation voltage, current transfer ratio, output voltage and current ratings, and saturation characteristics—establishes functional interchangeability in circuit applications. The identical 4-DIP through-hole package configuration permits direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

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

A: Yes. The Renesas Electronics version is a parametric equivalent with identical electrical specifications, isolation voltage, current transfer ratio, output ratings, and package configuration. Direct substitution is supported without circuit redesign.

Q: Are there differences in packaging between the two manufacturers?

A: The CEL version packaging is not specified in available documentation. The Renesas Electronics version is supplied in Tube packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What are the critical parameters that must match for substitution?

A: Substitution requires matching of isolation voltage (5000Vrms), channel count (1), output type (Transistor), current transfer ratio (80-160% @ 5mA), maximum output voltage (80V), output current (50mA), saturation voltage (300mV), and package configuration (4-DIP through-hole). Deviations in any of these parameters disqualify substitution.

Q: Are both versions compliant with environmental and regulatory standards?

A: Yes. Both the CEL and Renesas Electronics versions are ROHS3 compliant and REACH affected, meeting current environmental and regulatory requirements for industrial component applications.

Q: What is the operating temperature range for this optoisolator?

A: Both versions operate across -55°C to 100°C, supporting industrial and extended temperature applications.
