Key Parameters

Substitute Part Grouping Explanation

Substitution is determined by strict adherence to the following critical parameters:

• Voltage - Isolation: 5000Vrms (required match)
• Number of Channels: 1 (required match)
• Output Type: Transistor (required match)
• Current Transfer Ratio: 80% @ 5mA minimum, 160% @ 5mA maximum (required match)
• Voltage - Output (Max): 70V (required match)
• Current - Output / Channel: 30mA (required match)
• Rise / Fall Time (Typ): 3µs, 5µs (required match)
• Vce Saturation (Max): 300mV (required match)
• Operating Temperature: -55°C ~ 100°C (required match)
• Package / Case: 4-SMD, Gull Wing (required match)
• Mounting Type: Surface Mount (required match)

All listed substitutes maintain these parameters identically. Substitution grouping reflects variations in packaging format (Cut Tape vs. Tape & Reel), base product number designation (PS2501 vs. PS2561 series), and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: PS2501AL-1-F3-H-A (Renesas Electronics Corporation) provides direct manufacturer substitution with identical part number base (PS2501) and active product status. This part maintains full parametric equivalence while offering RoHS3 compliance and REACH compliance status unaffected by regulatory restrictions.

Secondary Recommendation: PS2561AL2-1-E3-H-A (CEL) supplies the highest inventory availability (71,808 units) while maintaining Tape & Reel packaging consistent with the original part. This parametric equivalent shares the same manufacturer and packaging format as the original PS2501AL-1-E3-H-A.

Alternative Options: PS2561AL-1-F3-H-A, PS2561AL-1-V-F3-H-A, and PS2561AL2-1-V-F3-H-A all maintain identical electrical parameters and active product status. Selection among these alternatives depends on packaging format requirements and procurement availability.

All substitute parts listed carry RoHS3 compliance and REACH compliance status superior to or equivalent with the original component, supporting modern regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can PS2561 series parts directly replace PS2501 series parts? A: Yes. The PS2561 series parts listed maintain identical electrical parameters including isolation voltage (5000Vrms), channel configuration (1 channel), current transfer ratio (80–160% @ 5mA), output voltage (70V maximum), output current (30mA), and switching characteristics (3µs, 5µs rise/fall time). These are parametric equivalents suitable for direct substitution.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging? A: Both packaging formats contain identical components in identical 4-SMD, Gull Wing configuration. Tape & Reel packaging supplies continuous tape suitable for high-volume automated assembly. Cut Tape packaging provides individual tape segments cut to specified lengths. Selection depends on procurement volume and assembly equipment compatibility.

Q: Why is the original PS2501AL-1-E3-H-A listed as obsolete? A: Obsolete designation indicates the manufacturer has discontinued production. Substitute parts maintain all electrical and mechanical specifications while offering active product status and current availability, ensuring continuity of supply and design compatibility.

Q: Are all substitute parts RoHS3 compliant? A: PS2501AL-1-F3-H-A, PS2561AL-1-F3-H-A, PS2561AL-1-V-F3-H-A, and PS2561AL2-1-V-F3-H-A all carry RoHS3 compliance certification. PS2561AL2-1-E3-H-A does not specify RoHS status in the available data.

Q: Which substitute part has the highest inventory availability? A: PS2561AL2-1-E3-H-A (CEL manufacturer) shows 71,808 units in stock, significantly exceeding availability of other substitutes.

Q: Do substitutes maintain the same operating temperature range? A: Yes. All listed substitutes operate across -55°C to 100°C, matching the original specification.

Q: Is the 4-SMD gull wing package identical across all parts? A: Yes. All parts use identical 4-SMD, Gull Wing surface mount packaging suitable for SMT assembly processes without requiring changes to board layouts or equipment.
