PI3L301DKE Equivalent & Substitute Parts

Part Overview

The PI3L301DKE is an 8-channel telecommunications switch IC manufactured by Diodes Incorporated in a 48-TFSOP package. This component is classified as Obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design requirements and production continuity. The part operates within the 3V to 3.6V supply range and supports 10/100/1000 Base-T Ethernet switching applications with a maximum on-state resistance of 8Ohm and -3dB bandwidth of 700MHz.

Substitute Part Grouping Explanation

Substitution of the PI3L301DKE is determined by strict equivalence across the following critical parameters:

Number of Channels: 8 channels (mandatory match)
Multiplexer/Demultiplexer Circuit: 2:1 configuration (mandatory match)
On-State Resistance (Max): 8Ohm (mandatory match)
Voltage - Supply, Single (V+): 3V ~ 3.6V (mandatory match)
Operating Temperature: -40°C ~ 85°C (TA) (mandatory match)
Mounting Type: Surface Mount (mandatory match)
RoHS Status: ROHS3 Compliant (mandatory match)
Moisture Sensitivity Level (MSL): 1 (Unlimited) (mandatory match)

The substitute parts identified—TS3L301DGG, TS3L301DGGR, and TS3L301DGVR—all meet these electrical and mechanical requirements. Variations in packaging format (Tube, Cut Tape & Digi-Reel, or Tape & Reel) and package case dimensions do not affect functional equivalence when the supplier device package remains 48-TSSOP or 48-TVSOP.

Engineering Selection Recommendations

TS3L301DGGR is the primary recommended substitute. This part carries Active product status with the highest inventory availability (22,808 pcs), ensuring long-term supply continuity. It meets all mandatory electrical and mechanical parameters and is supplied in Cut Tape & Digi-Reel format, suitable for both manual and automated assembly operations.

TS3L301DGVR serves as an alternative when the 48-TVSOP package variant is required. This part maintains Active status and provides equivalent electrical performance with inventory of 2,715 pcs.

TS3L301DGG is available as a Last Time Buy option with 2,206 pcs in stock. This part is suitable for applications where Tube packaging is acceptable.

All three substitutes exceed the original -3dB bandwidth specification (900MHz versus 700MHz), providing enhanced performance margin for high-speed Ethernet switching applications.

Frequently Asked Questions (FAQ)

Q: Can TS3L301DGGR directly replace PI3L301DKE in existing designs?

A: Yes. TS3L301DGGR meets all mandatory electrical parameters: 8-channel configuration, 2:1 multiplexer/demultiplexer circuit, 8Ohm maximum on-state resistance, 3V to 3.6V supply voltage, and -40°C to 85°C operating temperature range. Surface mount mounting type and ROHS3 compliance are identical.

Q: What is the difference between TS3L301DGG, TS3L301DGGR, and TS3L301DGVR?

A: The three parts are electrically identical. Differences exist only in packaging format and product status. TS3L301DGG uses Tube packaging and carries Last Time Buy status. TS3L301DGGR uses Cut Tape & Digi-Reel packaging with Active status. TS3L301DGVR uses Tape & Reel packaging with Active status and a 48-TVSOP supplier device package variant.

Q: Does the increased -3dB bandwidth (900MHz vs. 700MHz) of the substitute parts affect circuit design?

A: No. The substitute parts' higher bandwidth specification is a performance enhancement that maintains backward compatibility. Circuits designed for 700MHz operation will function correctly with components rated for 900MHz.

Q: Are there package compatibility considerations when selecting between the three substitutes?

A: Yes. TS3L301DGGR and TS3L301DGG use 48-TSSOP supplier device package with different physical case dimensions (0.240" vs. 0.173" width). TS3L301DGVR uses 48-TVSOP package matching the original PI3L301DKE case width of 0.173". Verify PCB footprint compatibility before selection.

Q: Which substitute should be selected for new production designs?

A: TS3L301DGGR is recommended for new designs due to Active product status, highest inventory availability, and standard Cut Tape & Digi-Reel packaging suitable for high-volume manufacturing.
