Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PI3C3125WE is determined by strict alignment across the following critical parameters:

• Circuit Configuration: 1 x 1:1 topology with 4 independent circuits
• Voltage Supply Range: 2.3V ~ 3.6V single supply operation
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 14-SOIC (0.154", 3.90mm Width) surface mount
• Compliance Standards: ROHS3 Compliant, REACH Unaffected, MSL 1

The substitute parts identified—SN74CBTLV3125D and SN74CBTLV3126D from Texas Instruments—meet all these parameters identically. Both are Last Time Buy components, ensuring equivalent lifecycle status and supply considerations.

Parameter Comparison

Engineering Selection Recommendations

Both SN74CBTLV3125D and SN74CBTLV3126D are direct parametric equivalents to the PI3C3125WE. Selection between these alternatives should be based on:

Availability and Inventory: SN74CBTLV3125D maintains 2200 units in stock, while SN74CBTLV3126D has 1373 units available. The original PI3C3125WE has 2677 units in current inventory.

Compliance Alignment: All three parts carry identical ROHS3 compliance, REACH unaffected status, and MSL 1 ratings, ensuring regulatory and environmental compatibility across designs.

Last Time Buy Status: All parts share Last Time Buy product status, indicating equivalent supply lifecycle considerations. Long-term design strategies should account for this status across all three options.

Manufacturer Sourcing: Texas Instruments components (SN74CBTLV series) provide an alternative sourcing channel from Diodes Incorporated, supporting supply chain diversification.

Frequently Asked Questions (FAQ)

Q: Can SN74CBTLV3125D and SN74CBTLV3126D be used interchangeably with PI3C3125WE?

A: Yes. Both Texas Instruments parts meet all electrical and mechanical parameters specified for the PI3C3125WE, including voltage supply range (2.3V ~ 3.6V), operating temperature (-40°C ~ 85°C), circuit configuration (1 x 1:1 with 4 independent circuits), and 14-SOIC packaging. Pin-to-pin compatibility is maintained.

Q: What is the difference between SN74CBTLV3125D and SN74CBTLV3126D?

A: Both parts are functionally equivalent bus switches with identical electrical specifications and packaging. The difference lies in their base product numbers (74CBTLV3125 vs. 74CBTLV3126), but they share the same circuit topology, voltage range, temperature range, and physical form factor.

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

A: No. All three parts—PI3C3125WE, SN74CBTLV3125D, and SN74CBTLV3126D—carry identical ROHS3 compliance, REACH unaffected status, and MSL 1 ratings. They are equivalent from a regulatory and environmental standpoint.

Q: What should be considered when transitioning from PI3C3125WE to a substitute?

A: Since all parts share Last Time Buy status, transition planning should account for supply lifecycle. Verify PCB layout compatibility with the 14-SOIC package dimensions (0.154" width, 3.90mm). Confirm voltage supply capability (2.3V ~ 3.6V) and operating temperature requirements (-40°C ~ 85°C) match your application.

Q: Which substitute offers the best inventory availability?

A: SN74CBTLV3125D currently has 2200 units in stock, compared to 1373 units for SN74CBTLV3126D. The original PI3C3125WE maintains 2677 units. Inventory levels should be verified at time of procurement.
