PS2501L-1-F3-A Equivalent & Substitute Parts

Part Overview

The PS2501L-1-F3-A is a single-channel optoisolator with transistor output, rated for 5000Vrms isolation voltage. Manufactured by CEL, this component is designed for applications requiring galvanic isolation in low-speed switching circuits. The part is discontinued at DiGi Electronics, necessitating identification of functionally equivalent alternatives from active manufacturers. Substitute parts must maintain identical electrical characteristics and mechanical compatibility to ensure direct replacement capability in existing designs.

Substitute Part Grouping Explanation

Substitute parts for the PS2501L-1-F3-A are identified based on strict electrical and mechanical parameter matching within the optoisolator transistor output category. Substitution validity is determined by equivalence in the following critical parameters:

  • Single-channel configuration
  • 5000Vrms isolation voltage rating
  • Current transfer ratio range: 80% to 600% @ 5mA
  • Transistor output stage with 50mA maximum output current
  • 80V maximum output voltage
  • 4-SMD surface mount package with gull wing leads
  • Operating temperature range: -55°C to 100°C
  • DC input type

All identified substitutes maintain identical electrical performance specifications and mechanical compatibility, enabling direct board-level replacement without circuit redesign.

Engineering Selection Recommendations

Both Renesas Electronics Corporation alternatives—PS2501L-1-A and PS2501L-1-F3-A—provide complete electrical and mechanical equivalence to the discontinued CEL PS2501L-1-F3-A. Selection between these substitutes is determined by packaging and regulatory requirements:

PS2501L-1-A (Tube Packaging): Suitable for applications where tube packaging is acceptable. Carries REACH Affected status, requiring compliance verification in regulated markets.

PS2501L-1-F3-A (Cut Tape & Digi-Reel® Packaging): Recommended for automated assembly processes requiring tape-and-reel format. Maintains REACH Unaffected status, simplifying regulatory compliance in international applications.

Both substitutes are classified as "Not For New Designs" by Renesas, indicating mature product status. For new design initiatives, consultation with Renesas regarding long-term availability and alternative optoisolator families is advised.

Frequently Asked Questions (FAQ)

Q: Can PS2501L-1-A be used as a direct replacement for PS2501L-1-F3-A?

A: Yes. Both parts share identical electrical specifications across all critical parameters: 5000Vrms isolation, 1-channel transistor output, 50mA output current, and 4-SMD gull wing package. The primary difference is packaging format (tube versus cut tape). Direct board-level substitution is electrically valid.

Q: What is the difference between the two Renesas substitutes?

A: PS2501L-1-A is supplied in tube packaging, while PS2501L-1-F3-A is supplied in cut tape and Digi-Reel® format. Electrical performance is identical. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Are there compliance differences between the substitutes?

A: Yes. PS2501L-1-A carries REACH Affected status, while PS2501L-1-F3-A is REACH Unaffected. Both are ROHS3 compliant. Applications subject to REACH regulations should prioritize PS2501L-1-F3-A to minimize compliance documentation requirements.

Q: What does "Not For New Designs" status mean?

A: This designation indicates the product is in mature/end-of-life phase. Renesas continues to support existing applications but does not recommend these parts for new circuit designs. For new projects, alternative optoisolator solutions from Renesas should be evaluated.

Q: Is the 4-SMD gull wing package compatible with standard PCB assembly equipment?

A: Yes. The 4-SMD gull wing package is a standard surface mount configuration compatible with conventional pick-and-place and reflow soldering processes. No specialized assembly procedures are required.

Q: Can inventory from different packaging formats be mixed in production?

A: Electrically, yes. However, mixing tube and tape-and-reel formats in a single production run may complicate inventory tracking and assembly logistics. Standardizing on a single packaging format per production batch is recommended for process control.
