PS2703-1-F3-A Equivalent & Substitute Parts

Part Overview

The PS2703-1-F3-A is an optoisolator with transistor output designed for galvanic isolation in electronic circuits. This component provides 3750Vrms isolation voltage with single-channel transistor switching capability in a compact 4-SOP surface mount package. The main part (CEL manufacturer) is discontinued at DiGi Electronics, necessitating the identification of active alternative sources. Substitute parts from Renesas Electronics Corporation remain in active production status with identical electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution for the PS2703-1-F3-A is based on matching the following critical parameters:

Isolation Voltage: 3750Vrms (no derating permitted)
Channel Configuration: Single channel transistor output
Current Transfer Ratio Range: 50% to 400% @ 5mA
Output Specifications: 120V maximum, 30mA per channel
Switching Performance: 10µs rise and fall times
Operating Temperature: -55°C to 100°C
Package: 4-SOP surface mount (Gull Wing)
Compliance: ROHS3 compliant, REACH unaffected

The substitute parts PS2703-1-F3-A and PS2703-1-V-F3-A (both from Renesas Electronics Corporation) maintain identical electrical and mechanical specifications to the original part, differing only in packaging format (Tape & Reel) and product status (Active vs. Discontinued).

Engineering Selection Recommendations

Both Renesas Electronics Corporation alternatives are suitable direct substitutes for the discontinued CEL PS2703-1-F3-A. Selection between the two active parts should be based on the following factors:

PS2703-1-F3-A (Renesas): Preferred for high-volume applications with standard packaging requirements. Maintains larger inventory availability (25305 units in stock) and active production status ensures long-term supply continuity.

PS2703-1-V-F3-A (Renesas): Suitable for applications where alternate packaging or device variant is acceptable. Active product status guarantees ongoing manufacturing support, though inventory levels are lower (8280 units in stock).

Both parts maintain identical electrical performance across isolation voltage, switching speed, current transfer ratio specifications, and operating temperature range. ROHS3 compliance and REACH unaffected status are equivalent across all variants. Package specifications remain consistent (4-SOP, Gull Wing, surface mount).

Frequently Asked Questions (FAQ)

Q: Can PS2703-1-V-F3-A be used in place of PS2703-1-F3-A? A: Yes. Both parts are parametric equivalents with identical electrical and mechanical specifications. The difference lies in the device variant designation (indicated by the "-V-" suffix) and Tape & Reel packaging format.

Q: What determines substitutability for this optoisolator? A: Substitutability is determined by matching isolation voltage (3750Vrms), channel configuration (single transistor output), current transfer ratio range (50-400% @ 5mA), output voltage/current ratings (120V, 30mA), switching performance (10µs rise/fall times), operating temperature range (-55°C to 100°C), and package type (4-SOP surface mount).

Q: Are there pin-to-pin compatibility concerns? A: No. All three parts use identical 4-SOP Gull Wing package geometry with equivalent pinout and physical dimensions.

Q: What is the difference between the CEL and Renesas versions? A: The CEL version is discontinued from DiGi Electronics. The Renesas versions are active production parts with identical specifications. Renesas is the current qualified manufacturer for ongoing supply.

Q: Are moisture sensitivity and storage requirements different? A: No. All variants maintain MSL 1 (Unlimited) moisture sensitivity level, indicating no special dry-pack requirements or storage restrictions.

Q: Does RoHS or REACH compliance differ between substitutes? A: No. All parts maintain ROHS3 compliance and REACH unaffected status, suitable for equivalent regulatory environments.
