PI3C3126LE Equivalent & Substitute Parts

Part Overview

The PI3C3126LE is a bus switch IC manufactured by Diodes Incorporated, configured as a 1 x 1:1 logic switch in a 14-TSSOP surface mount package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement.

The PI3C3126LE operates with a single supply voltage ranging from 2.3V to 3.6V and provides four independent circuits for signal switching applications. Its obsolete status requires designers to evaluate available alternatives that maintain functional and electrical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI3C3126LE are evaluated based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Package / Case: 14-TSSOP form factor (0.173", 4.40mm Width)
• Mounting Type: Surface Mount
• Voltage Supply Source: Single Supply
• Bus Switch Type: Logic switching functionality
• RoHS Status: ROHS3 Compliant

Substitute Categories:

Direct Equivalent (Same Manufacturer): PI3C3126LEX maintains identical electrical specifications and circuit configuration (1 x 1:1, 4 independent circuits) with the same voltage supply range (2.3V ~ 3.6V). The primary difference is packaging format (Tape & Reel vs. standard packaging) and product status (Last Time Buy vs. Obsolete).

Cross-Manufacturer Substitute: TC7MBL3126CFT(EL) from Toshiba Semiconductor and Storage provides bus switch functionality in the same 14-TSSOP package. While the circuit configuration differs (4 x 1:1 vs. 1 x 1:1), it maintains the same independent circuit count (4 circuits) and package compatibility. The voltage supply range is broader (1.65V ~ 3.6V), and the part is currently Active in production status.

Parameter Comparison

Engineering Selection Recommendations

PI3C3126LEX (Direct Equivalent): This part is the primary substitute for the PI3C3126LE. It maintains identical electrical specifications and circuit configuration while offering the same ROHS3 compliance and MSL rating. The Last Time Buy status indicates limited availability, making this a transitional solution rather than a long-term alternative.

TC7MBL3126CFT(EL) (Cross-Manufacturer Substitute): This Toshiba part provides the most sustainable long-term alternative due to its Active product status. It maintains the same 14-TSSOP package footprint and surface mount compatibility. The broader voltage supply range (1.65V ~ 3.6V) provides additional operational flexibility compared to the PI3C3126LE. ROHS3 compliance and MSL rating 1 ensure regulatory and environmental compatibility. The circuit configuration difference (4 x 1:1 vs. 1 x 1:1) requires application-level evaluation to confirm functional suitability.

Frequently Asked Questions (FAQ)

Q: Can PI3C3126LEX be used as a direct replacement for PI3C3126LE?

A: Yes. PI3C3126LEX maintains identical electrical specifications, circuit configuration (1 x 1:1), independent circuit count (4), voltage supply range (2.3V ~ 3.6V), and package form factor (14-TSSOP). The primary difference is packaging format (Tape & Reel) and product status (Last Time Buy). PCB layout and design remain unchanged.

Q: What is the key difference between PI3C3126LE and TC7MBL3126CFT(EL)?

A: The circuit configuration differs: PI3C3126LE is 1 x 1:1 while TC7MBL3126CFT(EL) is 4 x 1:1. Both maintain 4 independent circuits and the same 14-TSSOP package. TC7MBL3126CFT(EL) offers a broader voltage supply range (1.65V ~ 3.6V) and Active product status. Application-level verification is required to confirm functional compatibility.

Q: Are all substitute parts in the same package?

A: Yes. All parts listed (PI3C3126LE, PI3C3126LEX, and TC7MBL3126CFT(EL)) use the 14-TSSOP surface mount package with identical physical dimensions (0.173", 4.40mm Width). PCB footprints are compatible.

Q: Do all parts meet RoHS and MSL requirements?

A: Yes. All parts are ROHS3 compliant with MSL rating 1 (Unlimited), ensuring regulatory compliance and environmental compatibility across all substitutes.

Q: Why is TC7MBL3126CFT(EL) recommended for new designs?

A: TC7MBL3126CFT(EL) has Active product status, ensuring long-term availability and supply chain stability. PI3C3126LE is Obsolete and PI3C3126LEX is Last Time Buy, both indicating limited future procurement options.
