PS2502-4-A Equivalent & Substitute Parts

Part Overview

The PS2502-4-A is a 4-channel optoisolator with Darlington output, designed for high-voltage isolation applications requiring 5000Vrms isolation capability. This component is discontinued at DiGi Electronics (CEL manufacturer) and marked as "Not For New Designs" by Renesas Electronics Corporation, making identification of functionally equivalent alternatives essential for ongoing system support and new designs requiring this isolation specification.

Substitute Part Grouping Explanation

Substitute relationships for the PS2502-4-A are established based on the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Number of Channels: 4 (exact match required)
• Voltage - Isolation: 5000Vrms (exact match required)
• Output Type: Darlington (exact match required)
• Current Transfer Ratio (Min): 200% @ 1mA (exact match required)
• Voltage - Output (Max): 40V (exact match required)
• Current - Output / Channel: 160mA (exact match required)
• Operating Temperature Range: -55°C ~ 100°C (exact match required)

Mechanical Equivalence Criteria:

• Package / Case: 16-DIP (0.300", 7.62mm) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Input Type: DC (exact match required)

The PS2502-4-A from CEL and the PS2502-4-A from Renesas Electronics Corporation represent the same parametric equivalent, differing only in manufacturer and product status designation.

Parameter Comparison

Engineering Selection Recommendations

The PS2502-4-A from Renesas Electronics Corporation provides parametric equivalence to the CEL PS2502-4-A across all specified electrical and mechanical parameters. Both variants maintain ROHS3 compliance and identical performance specifications for isolation voltage, channel configuration, output characteristics, and package form factor.

The Renesas variant is designated as "Not For New Designs," indicating long-term availability constraints. For systems currently using the discontinued CEL variant, direct substitution with the Renesas PS2502-4-A is electrically and mechanically valid based on matching isolation specification (5000Vrms), output configuration (4-channel Darlington), and physical package format (16-DIP through-hole).

Frequently Asked Questions (FAQ)

Q: Can the Renesas PS2502-4-A directly replace the CEL PS2502-4-A in existing designs? A: Yes. The Renesas variant is parametrically equivalent across all specified electrical and mechanical parameters, including isolation voltage (5000Vrms), channel count (4), output type (Darlington), current handling (160mA per channel), and package format (16-DIP through-hole).

Q: What parameters define substitution eligibility for this optoisolator? A: Substitution requires matching on: isolation voltage (5000Vrms), number of channels (4), output type (Darlington), current transfer ratio (200% @ 1mA), maximum output voltage (40V), output current per channel (160mA), package (16-DIP 0.300" spacing), and operating temperature range (-55°C to 100°C).

Q: Are there any compliance differences between the CEL and Renesas variants? A: Both variants are ROHS3 compliant, REACH affected, and classified under ECCN EAR99. No compliance differentiation exists between the two manufacturers for this part number.

Q: Why is the Renesas variant marked "Not For New Designs"? A: This designation indicates that Renesas has determined long-term product availability constraints. For systems requiring this specific optoisolator specification where the CEL variant is unavailable, the Renesas equivalent remains the parametric substitute.

Q: What is the significance of the 16-DIP package format for substitution? A: The 16-DIP (0.300" pitch, 7.62mm) through-hole package is a critical mechanical specification. Any substitute must use identical package geometry for direct PCB compatibility without layout modifications.
