PS2501AL-1-F3-H-A Equivalent & Substitute Parts

Part Overview

The PS2501AL-1-F3-H-A is a 5000Vrms optoisolator with transistor output in a 4-SMD surface mount package. This component provides electrical isolation for low-speed switching and signal transmission applications. The main part (CEL manufacturer) is discontinued at DiGi Electronics, necessitating evaluation of available substitutes to maintain supply chain continuity and ensure design compatibility with production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of optoisolators is determined by matching the following critical electrical and mechanical parameters:

Electrical Parameters:

• Voltage - Isolation: 5000Vrms (mandatory match)
• Number of Channels: 1 (mandatory match)
• Output Type: Transistor (mandatory match)
• Current Transfer Ratio range: 80-160% @ 5mA (mandatory match)
• Voltage - Output (Max): 70V (mandatory match)
• Current - Output / Channel: 30mA (mandatory match)
• Vce Saturation (Max): 300mV (mandatory match)
• Operating Temperature Range: -55°C ~ 100°C (mandatory match)

Mechanical Parameters:

• Package / Case: 4-SMD, Gull Wing (mandatory match for PCB compatibility)
• Mounting Type: Surface Mount (mandatory match)

Compliance:

• RoHS Status: ROHS3 Compliant (mandatory match)

Two substitute parts match all critical parameters and are identified as parametric equivalents. Differences exist only in manufacturer attribution, product status, packaging format, and inventory availability.

Parameter Comparison

Engineering Selection Recommendations

PS2501AL-1-F3-H-A (Renesas Electronics Corporation): This is the primary recommended substitute. It is manufactured by Renesas Electronics Corporation with Active product status, ensuring ongoing support and supply availability. All electrical and mechanical specifications are identical to the discontinued CEL part. It is supplied in Cut Tape (CT) format and carries full ROHS3 compliance and EAR99 ECCN status.

PS2561AL2-1-E3-H-A (CEL): This part is also a parametric equivalent with identical electrical performance and identical 4-SMD, Gull Wing package configuration. It maintains Active product status from the same manufacturer as the original part. It is available in higher inventory quantities (71,808 pcs) supplied in Tape & Reel (TR) format. It carries ROHS3 compliance and EAR99 ECCN status, with the exception that MSL rating is not provided in available documentation.

Both substitutes are suitable for direct replacement in designs currently specified with PS2501AL-1-F3-H-A. Selection between the two substitutes depends on packaging format requirements (Cut Tape versus Tape & Reel), inventory availability, and lead-time needs.

Frequently Asked Questions (FAQ)

Q: Can I directly replace PS2501AL-1-F3-H-A with either of the listed substitutes? A: Yes. Both substitutes (PS2501AL-1-F3-H-A from Renesas and PS2561AL2-1-E3-H-A from CEL) match all critical electrical and mechanical parameters, including isolation voltage, output type, current handling, temperature range, and physical package configuration. No design modifications are required.

Q: What are the key differences between the available substitutes? A: The primary differences are manufacturer attribution, product status, packaging format, and inventory levels. The Renesas part is supplied in Cut Tape format with higher inventory (9,828 pcs). The CEL part PS2561AL2-1-E3-H-A is supplied in Tape & Reel format with substantially higher inventory (71,808 pcs). Both are electrically and mechanically equivalent.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect PCB assembly compatibility? A: Packaging format affects supply chain handling and feeder compatibility in pick-and-place equipment. Both Cut Tape (CT) and Tape & Reel (TR) formats are standard surface mount supply formats. Confirm your assembly process supports the selected packaging format before procurement.

Q: Are all substitutes RoHS compliant? A: Yes. Both substitute parts carry ROHS3 Compliant status, maintaining environmental and regulatory compliance equivalent to the original part.

Q: What is the operating temperature range for these parts? A: All parts, including both substitutes, operate across the temperature range of -55°C to 100°C, providing identical thermal performance for application design.

Q: Can I mix parts from different substitutes in the same design or production run? A: Yes. Since all substitutes are parametric equivalents with identical electrical specifications and package configurations, they are functionally interchangeable. However, procurement and inventory management practices should determine whether multiple part numbers are used.
