PI3L301DAEX Equivalent & Substitute Parts

Part Overview

The PI3L301DAEX is a telecommunications switch IC manufactured by Diodes Incorporated, designed for 8-channel multiplexing and demultiplexing applications. This 48-TSSOP surface mount device operates at 3V to 3.6V single supply with a maximum on-state resistance of 8 ohms and supports 10/100/1000 Base-T connectivity. The part is currently in Last Time Buy status, making identification of compatible substitutes essential for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PI3L301DAEX is determined by strict equivalence across the following critical parameters:

• Package compatibility: 48-TFSOP form factor with identical 0.240" width and 6.10mm dimensions
• Electrical performance: 2:1 multiplexer/demultiplexer configuration with 8 channels
• Supply voltage: 3V to 3.6V single supply operation
• On-state resistance: Maximum 8 ohms
• Operating temperature range: -40°C to 85°C
• Compliance standards: ROHS3 compliance and REACH unaffected status

The TS3L301DGGR from Texas Instruments meets all these substitution criteria. While it offers enhanced bandwidth (900 MHz versus 700 MHz) and additional feature support (LVDS, LVPECL), these represent functional improvements rather than deviations from the core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The TS3L301DGGR qualifies as a direct substitute for the PI3L301DAEX based on electrical and mechanical parameter equivalence. The PI3L301DAEX is designated Last Time Buy, indicating end-of-life status, while the TS3L301DGGR maintains Active product status with higher inventory availability (22,808 units versus 2,133 units). Both devices maintain identical compliance certifications: ROHS3 compliance, REACH unaffected status, and MSL Level 1 rating.

The TS3L301DGGR provides superior bandwidth performance (900 MHz versus 700 MHz) and extended feature support without compromising core electrical specifications. For new designs or long-term procurement strategies, the TS3L301DGGR is the appropriate selection. For existing designs currently using the PI3L301DAEX, the TS3L301DGGR provides a compatible upgrade path.

Frequently Asked Questions (FAQ)

Q: Can the TS3L301DGGR directly replace the PI3L301DAEX in existing PCB layouts?

A: Yes. Both devices use identical 48-TFSOP packaging with matching pin configurations, supply voltage requirements (3V to 3.6V), and on-state resistance specifications (8 ohms maximum). No PCB redesign is required.

Q: What is the significance of the bandwidth difference between these parts?

A: The TS3L301DGGR operates at 900 MHz -3dB bandwidth compared to 700 MHz for the PI3L301DAEX. This represents enhanced signal integrity performance and is not a limiting factor for substitution. Applications requiring 700 MHz performance will operate within specification on the TS3L301DGGR.

Q: Are there any compliance or certification differences between these parts?

A: No. Both devices are ROHS3 compliant, REACH unaffected, and carry identical MSL Level 1 (Unlimited) moisture sensitivity ratings. Regulatory and environmental compliance requirements are equivalent.

Q: Why is the PI3L301DAEX designated Last Time Buy?

A: Last Time Buy status indicates the manufacturer is discontinuing this product line. The TS3L301DGGR from Texas Instruments represents the active alternative for ongoing procurement and new design implementations.

Q: Are there packaging format alternatives available?

A: Both the PI3L301DAEX and TS3L301DGGR are supplied in 48-TSSOP packaging. The PI3L301DAEX is available in Tape & Reel format, while the TS3L301DGGR is available in Cut Tape and Digi-Reel formats. All formats are compatible with standard surface mount assembly processes.
