PS2514-1Y-A Equivalent & Substitute Parts

Part Overview

The PS2514-1Y-A is a 5000Vrms optoisolator with transistor output in a 4-DIP package, designed for DC input applications requiring galvanic isolation in Through Hole mounting configurations. The original manufacturer CEL has discontinued this part at DiGi Electronics, creating the necessity to identify active equivalent sources from alternative manufacturers. Renesas Electronics Corporation currently offers parametric equivalents in active product status, ensuring continued supply chain availability for this isolation component category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2514-1Y-A is determined by strict electrical and mechanical parameter matching across the optoisolator category. The following parameters establish substitution validity:

Critical Matching Parameters:

• Voltage - Isolation: 5000Vrms (mandatory for galvanic isolation performance)
• Number of Channels: 1 (functional requirement)
• Output Type: Transistor (circuit topology requirement)
• Current Transfer Ratio range: 50% @ 5mA minimum, 200% @ 5mA maximum
• Voltage - Output (Max): 40V
• Current - Output / Channel: 20mA
• Package / Case: 4-DIP (0.300", 7.62mm) mechanical form factor
• Mounting Type: Through Hole

Compliance Parameters:

• RoHS3 Compliant
• MSL: 1 (Unlimited)
• ECCN: EAR99
• HTSUS: 8541.49.8000

All substitute parts must match these parameters precisely. Minor variations in non-critical specification fields (such as Turn On/Turn Off Time versus Rise/Fall Time documentation) do not affect substitution validity when core electrical characteristics are identical.

Parameter Comparison

Engineering Selection Recommendations

PS2514-1Y-A (Renesas Electronics Corporation) is the direct equivalent offering from an active manufacturer with identical electrical specifications and active product status. This part is the primary substitute for the discontinued CEL version, providing complete functional interchangeability without design modifications.

PS2514-1Y-V-A (Renesas Electronics Corporation) is a parametric equivalent sharing all critical electrical characteristics and mechanical form factor. This part is currently in active production status with higher inventory availability. The REACH compliance status differs (Unaffected versus Affected), which may be relevant for specific regulatory requirements. All electrical parameters meet or exceed the original specification requirements.

Both Renesas optoisolators are ROHS3 Compliant with EAR99 export classification and unlimited moisture sensitivity rating, maintaining full regulatory compliance for the optoisolator category. Selection between the two Renesas options should be based on supply chain availability, regulatory requirements regarding REACH status, and project-specific compliance mandates.

Frequently Asked Questions (FAQ)

Q: Can PS2514-1Y-A (Renesas) directly replace the discontinued PS2514-1Y-A (CEL) without design modifications?

A: Yes. The Renesas PS2514-1Y-A maintains identical electrical parameters, current transfer ratios, isolation voltage, output voltage/current ratings, and 4-DIP through-hole package configuration. Direct socket substitution is supported.

Q: What is the difference between PS2514-1Y-A and PS2514-1Y-V-A from Renesas?

A: Both parts are parametric equivalents with identical isolation voltage, current transfer ratios, output specifications, and 4-DIP packaging. The primary differences are REACH compliance status (Affected versus Unaffected) and potential variations in timing specification documentation (Turn On/Turn Off Time versus Rise/Fall Time). All electrical performance parameters are identical.

Q: Are the 4-DIP packages mechanically interchangeable?

A: Yes. Both substitute parts use the 4-DIP (0.300", 7.62mm) standard package format with Through Hole mounting compatibility. PCB layouts designed for the original PS2514-1Y-A require no modification.

Q: What supply chain considerations apply to these substitutes?

A: The PS2514-1Y-A (Renesas) carries the same series designation (NEPOC) as the original CEL part. The PS2514-1Y-V-A (Renesas) demonstrates higher inventory availability (4631 Pcs versus 1479 Pcs). Both are currently in active production status.

Q: Do these substitutes maintain RoHS3 compliance?

A: Yes. Both Renesas substitute parts are ROHS3 Compliant with MSL rating of 1 (Unlimited) and EAR99 export classification, matching the environmental and regulatory profile of the discontinued CEL original.
