TS3L301DGG Equivalent & Substitute Parts

Part Overview

The TS3L301DGG is an Ethernet switch IC manufactured by Texas Instruments, designed for networking applications requiring 8-channel multiplexing/demultiplexing functionality in a 48-TSSOP package. This device operates as a 2:1 SPDT switch with 8Ω on-state resistance and supports 10/100/1000 Base-T, LVDS, and LVPECL signaling standards. The TS3L301DGG is currently in Last Time Buy status, making identification of equivalent and substitute parts essential for design continuity and long-term component sourcing strategy.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TS3L301DGG are qualified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Multiplexer/Demultiplexer Circuit: 2:1
• Number of Channels: 8
• On-State Resistance (Max): 8Ω
• Voltage - Supply, Single (V+): 3V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C (TA)
• Package / Case: 48-TFSOP (0.240", 6.10mm Width)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

• -3dB Bandwidth: 900MHz or greater
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Parts meeting all primary criteria and secondary parameters are considered direct substitutes. Variations in bandwidth or feature sets (such as LVDS/LVPECL support) do not preclude substitution when core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

TS3L301DGGR (Texas Instruments): This part is the manufacturer-recommended substitute for the TS3L301DGG. It maintains identical electrical specifications, including 900MHz bandwidth and SPDT switch configuration, while offering Active product status and significantly higher inventory availability (22,808 pcs vs. 2,206 pcs). The primary difference is packaging format: TS3L301DGGR is supplied in Cut Tape (CT) & Digi-Reel® format, whereas the TS3L301DGG is supplied in Tube format. Both are ROHS3 compliant with MSL 1 rating. This substitute is preferred for new designs and ongoing production requiring assured long-term availability.

PI3L301DAEX (Diodes Incorporated): This part meets all primary substitution criteria with identical channel count, on-state resistance, supply voltage, and operating temperature range. However, the -3dB bandwidth is specified at 700MHz, which is 200MHz lower than the TS3L301DGG. The PI3L301DAEX is supplied in Tape & Reel (TR) format and carries Last Time Buy status. This substitute is suitable for applications where the 700MHz bandwidth specification is sufficient and where cross-manufacturer sourcing is acceptable. ROHS3 compliance and MSL 1 rating are maintained.

Both substitutes are electrically and mechanically compatible with the TS3L301DGG within the specified parameter tolerances. Selection should be based on application bandwidth requirements, packaging format compatibility with assembly processes, and long-term availability strategy.

Frequently Asked Questions (FAQ)

Q: Can TS3L301DGGR be used as a direct replacement for TS3L301DGG in existing designs?

A: Yes. The TS3L301DGGR is electrically and mechanically identical to the TS3L301DGG. Both devices feature 2:1 multiplexing, 8 channels, 8Ω on-state resistance, 3V–3.6V supply voltage, 900MHz bandwidth, and 48-TFSOP packaging. The primary difference is packaging format (Cut Tape & Digi-Reel® vs. Tube), which affects procurement and assembly handling but not electrical performance or PCB footprint.

Q: What is the bandwidth difference between TS3L301DGG and PI3L301DAEX?

A: The TS3L301DGG specifies 900MHz -3dB bandwidth, while the PI3L301DAEX specifies 700MHz. This 200MHz difference may be significant for high-speed Ethernet applications operating at or near the device bandwidth limits. Applications requiring full 900MHz performance should use TS3L301DGG or TS3L301DGGR.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 48-TFSOP package with identical pinout and footprint. PCB layout modifications are not required when substituting between these parts.

Q: What is the significance of Last Time Buy status for TS3L301DGG?

A: Last Time Buy status indicates that the manufacturer will no longer produce this part after a specified date. Existing inventory will be depleted, and no new production runs are planned. TS3L301DGGR (Active status) is the recommended long-term alternative for continued sourcing.

Q: Do all three parts meet RoHS3 compliance requirements?

A: Yes. TS3L301DGG, TS3L301DGGR, and PI3L301DAEX are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard PCB assembly and storage conditions.

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

A: TS3L301DGGR is recommended for new designs. It offers Active product status, higher inventory availability, and identical electrical specifications to the TS3L301DGG. PI3L301DAEX may be considered if bandwidth requirements do not exceed 700MHz and cross-manufacturer sourcing is acceptable.
