Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2561-1-V-H-A is based on strict parametric equivalence in the following critical categories:

Electrical Specifications: Isolation voltage (5000Vrms), number of channels (1), output type (Transistor), current transfer ratio range (80% - 160% @ 5mA), maximum output voltage (80V), output current per channel (50mA), and saturation voltage (300mV maximum).

Mechanical Compatibility: Package type (4-DIP), package dimensions (0.300", 7.62mm), and through-hole mounting configuration.

Environmental & Compliance: Operating temperature range (-55°C ~ 100°C), RoHS3 compliance, and REACH applicability.

The PS2501-1-H-A from Renesas Electronics Corporation meets all specified parameters and qualifies as a direct parametric equivalent.

Frequently Asked Questions (FAQ)

Q: What makes the PS2501-1-H-A a suitable replacement for the PS2561-1-V-H-A?

A: Both parts are parametrically identical across all critical specifications: 5000Vrms isolation voltage, single-channel transistor output, identical current transfer ratio (80%-160% @ 5mA), matching output voltage and current ratings, identical saturation voltage, and equivalent operating temperature range. Both use identical 4-DIP through-hole packaging with 0.300" (7.62mm) dimensions and maintain equivalent RoHS3 and REACH compliance.

Q: Are there any package or pinout differences between these parts?

A: No. Both the PS2561-1-V-H-A and PS2501-1-H-A use 4-DIP (0.300", 7.62mm) through-hole packaging with identical physical dimensions and mounting requirements. Direct board-level substitution is applicable without layout modifications.

Q: What is the impact of the product status change?

A: The PS2561-1-V-H-A is discontinued at DiGi Electronics, which impacts long-term availability and procurement reliability. The PS2501-1-H-A maintains active product status from Renesas Electronics Corporation, ensuring supply continuity and ongoing manufacturer support.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the PS2561-1-V-H-A and PS2501-1-H-A are ROHS3 compliant and REACH affected, satisfying identical environmental and regulatory requirements for applications requiring these certifications.
