Substitute Part Grouping Explanation

Substitute parts for the PS2514L-1Y-A optoisolator are identified based on strict parametric equivalence. The following criteria determine substitutability:

Critical Matching Parameters:

• Voltage - Isolation: 5000Vrms
• Number of Channels: 1
• Output Type: Darlington
• Current Transfer Ratio range: 50% to 200% @ 5mA
• Rise / Fall Time: 15µs, 15µs
• Voltage - Output (Max): 40V
• Current - Output / Channel: 20mA
• Vce Saturation (Max): 350mV
• Operating Temperature range: -55°C ~ 100°C
• Package / Case: 4-SMD, Gull Wing
• Input Type: DC

All substitute parts must match these parameters exactly to ensure functional and electrical compatibility within the original application circuit.

The Renesas Electronics PS2514L-1Y-A maintains active product status with higher inventory availability (5493 pcs vs. 1154 pcs). Both parts comply with ROHS3 and REACH requirements, ensuring regulatory compliance in target applications. The identical package configuration (4-SMD, Gull Wing) and electrical parameters enable direct substitution without circuit redesign.

The Renesas part is supplied in Tube packaging, whereas the original CEL part packaging is not specified. Verify packaging requirements for your procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the Renesas PS2514L-1Y-A replace the CEL PS2514L-1Y-A in existing designs?

A: Yes. Both parts are parametrically identical across all critical electrical specifications including isolation voltage (5000Vrms), output type (Darlington), current transfer ratio (50-200% @ 5mA), and package configuration (4-SMD, Gull Wing). Direct substitution is supported without circuit modification.

Q: What are the key parameters that determine substitutability for this optoisolator?

A: Substitutability is determined by matching: isolation voltage (5000Vrms), number of channels (1), output type (Darlington), current transfer ratio range (50-200% @ 5mA), rise/fall time (15µs each), maximum output voltage (40V), output current per channel (20mA), Vce saturation (350mV maximum), operating temperature range (-55°C to 100°C), and package type (4-SMD, Gull Wing).

Q: Are there compliance or certification differences between the two parts?

A: No. Both the CEL and Renesas Electronics PS2514L-1Y-A parts are ROHS3 compliant, REACH affected, and classified under ECCN EAR99. Moisture sensitivity level is identical (MSL 1 - Unlimited) for both parts.

Q: What is the difference in packaging between these parts?

A: The Renesas Electronics PS2514L-1Y-A is supplied in Tube packaging. The original CEL part packaging specification is not provided. Confirm packaging compatibility with your assembly and storage requirements.

Q: Why is the original CEL part discontinued?

A: The CEL PS2514L-1Y-A is discontinued at DiGi Electronics. The Renesas Electronics equivalent maintains active product status with established supply chain availability.
