Parameter Comparison

Engineering Selection Recommendations

The PS2913-1-M-AX manufactured by Renesas Electronics Corporation is a direct parametric equivalent to the discontinued CEL PS2913-1-M-AX. Both components share identical electrical specifications, timing characteristics, and physical packaging.

Selection Basis:

The Renesas Electronics version maintains active product status, ensuring ongoing availability and supply chain continuity. Both variants comply with ROHS3 requirements and carry REACH Unaffected designation, meeting current regulatory standards for electronic component procurement.

The identical parameter set across isolation voltage, current transfer ratio, switching timing, output characteristics, and operating temperature range ensures functional interchangeability in existing circuit designs without modification to PCB layout, component footprint, or electrical interface requirements.

Frequently Asked Questions (FAQ)

Q: Can the Renesas Electronics PS2913-1-M-AX directly replace the discontinued CEL PS2913-1-M-AX?

A: Yes. Both components are parametrically identical across all specified electrical, timing, and physical characteristics. No circuit redesign or PCB modification is required.

Q: Are there any differences in packaging between the two manufacturers?

A: No. Both use 4-SMD surface mount packaging with flat leads. Moisture sensitivity level (MSL 1) and handling requirements are identical.

Q: What is the significance of the identical part number across manufacturers?

A: The PS2913-1-M-AX designation indicates a standardized component specification. Renesas Electronics manufactures this part to the same electrical and mechanical standards as the original CEL version.
