PS2506L-1-A Optoisolator Equivalent & Substitute Parts

Part Overview

The PS2506L-1-A is a 5000Vrms optoisolator with Darlington output configuration in a 4-SMD package. This component provides galvanic isolation for AC and DC input signals with a maximum isolation voltage of 5000Vrms. The main part (PS2506L-1-A from CEL) is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active suppliers to maintain supply chain continuity and support ongoing design requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PS2506L-1-A is based on matching the following critical electrical and mechanical parameters:

• Voltage - Isolation: 5000Vrms isolation voltage is the primary requirement for galvanic separation
• Output Configuration: Darlington output type and current characteristics (200% CTR @ 1mA)
• Output Ratings: Maximum output voltage (40V) and channel current (200mA)
• Package Type: 4-SMD, Gull Wing surface mount configuration
• Input Flexibility: AC and DC input signal compatibility
• Operating Temperature Range: -55°C to 100°C continuous operation
• Series Standard: NEPOC series designation ensures design compatibility

All identified substitutes maintain 100% parameter equivalence across these dimensions. Parts are grouped by product availability status and packaging configuration.

Engineering Selection Recommendations

Primary Substitute: PS2506L-1-F3-A (Renesas Electronics Corporation)

The PS2506L-1-F3-A is the recommended primary substitute. It maintains full parametric equivalence to the original PS2506L-1-A (CEL) across all critical electrical and mechanical specifications. This part carries Active product status from Renesas and offers superior supply chain availability with 8889 units in current inventory. The Tape & Reel (TR) packaging format provides optimal support for automated assembly operations in high-volume production environments. REACH Unaffected status provides additional regulatory advantage for international distribution and export applications.

Secondary Substitute: PS2506L-1-A (Renesas Electronics Corporation)

The Renesas-manufactured PS2506L-1-A (base product number PS2506) provides a secondary substitution option with identical parametric specifications. This variant is supplied in Tube packaging and maintains Active product status with 3788 units in inventory. This configuration supports both manual and semi-automated assembly workflows. REACH Affected status aligns with the original part designation.

Cross-manufacturer compatibility: Both Renesas alternatives meet the PS2506 base product number specification and NEPOC series standard, confirming full design compatibility and functional interchangeability with the discontinued CEL part.

Frequently Asked Questions (FAQ)

Q: Can PS2506L-1-F3-A and PS2506L-1-A (Renesas variants) be used interchangeably with the original PS2506L-1-A (CEL)?

A: Yes. Both Renesas parts maintain 100% electrical and mechanical parameter equivalence to the original CEL component. Isolation voltage (5000Vrms), Darlington output configuration, current transfer ratio (200% @ 1mA), output ratings (40V max, 200mA per channel), and packaging (4-SMD, Gull Wing) are identical. Both parts operate across the same temperature range (-55°C to 100°C) and support AC/DC input signals with equivalent rise/fall times (100µs).

Q: What is the difference between PS2506L-1-F3-A and PS2506L-1-A from Renesas?

A: The primary difference is packaging configuration. PS2506L-1-F3-A ships in Tape & Reel (TR) format, optimized for high-speed automated pick-and-place assembly. PS2506L-1-A ships in Tube packaging, suitable for manual and semi-automated assembly processes. Both parts are electrically identical and carry the same NEPOC series designation. Inventory availability differs (8889 vs. 3788 units), with PS2506L-1-F3-A offering greater supply depth.

Q: Are there regulatory compliance differences between the substitute parts?

A: All three parts (CEL and both Renesas variants) are ROHS3 Compliant, MSL Level 1 (Unlimited), and classified as EAR99 export control category. The distinction exists in REACH status: PS2506L-1-F3-A (Renesas) is REACH Unaffected, while the original CEL part and Renesas PS2506L-1-A variant are REACH Affected. For applications requiring REACH Unaffected status, PS2506L-1-F3-A is the appropriate selection.

Q: Does the 5000Vrms isolation voltage specification apply to both continuous and transient overvoltage conditions?

A: The parameter value (5000Vrms) represents the rated isolation voltage for this optoisolator. All substitute parts maintain this specification without variation.

Q: Can these parts be used in designs requiring greater than 200mA output current per channel?

A: No. All three parts are rated for 200mA maximum continuous output current per channel. Designs requiring higher output current must specify alternative optoisolator models with higher current ratings.

Q: What is the significance of the 200% Current Transfer Ratio (CTR) minimum specification?

A: The 200% CTR @ 1mA minimum specification indicates the output current will be at least 2.0 times the input current when driven with 1mA forward current. This ratio remains consistent across all three substitute parts and represents a critical parameter for input signal-to-output current transfer calculation in circuit design.
