Substitute Part Grouping Explanation
Substitution of the PI5A124TEX-1413 is determined by strict equivalence across the following critical parameters:
Primary Substitution Criteria:
- Switch circuit configuration: SPDT topology
- Multiplexer ratio: 2:1
- On-state resistance: 10Ohm maximum
- Supply voltage compatibility: 2V ~ 6V single supply
- Package type: SOT-23-6 surface mount
- Operating temperature range: -40°C ~ 85°C minimum
Secondary Compatibility Factors:
- Channel-to-channel matching (ΔRon): 200mOhm
- Switching speed performance (Ton/Toff): 15ns / 7ns
- Bandwidth capability: 326MHz or greater
- Leakage current specifications: 200pA or lower
The PI5A124TEX variant (Cut Tape & Digi-Reel packaging) is a direct parametric equivalent to the PI5A124TEX-1413, differing only in packaging format and product lifecycle status. Cross-manufacturer alternatives (ADG819BRTZ-REEL7, ADG819BRTZ-REEL, MAX4599EUT+T, MAX4561EUT+T, ADG719SRJZ-EP-RL7) are listed as available substitutes and must be verified for identical electrical performance and package compatibility before implementation.

Engineering Selection Recommendations
PI5A124TEX-1413 (Primary Selection): The PI5A124TEX-1413 is recommended for new designs and ongoing production due to its Active product status and established supply availability (968 units in stock). This part maintains full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for commercial and industrial applications.
PI5A124TEX (Alternative Packaging): The PI5A124TEX variant is electrically identical to the main part but carries Last Time Buy status, indicating limited future availability. This option is suitable only for existing designs requiring Cut Tape or Digi-Reel packaging formats where inventory can be secured immediately. Designers should transition to the PI5A124TEX-1413 for long-term production continuity.
Cross-Manufacturer Alternatives: Cross-manufacturer substitutes (ADG series from Analog Devices, MAX series from Maxim Integrated) are listed as available options but require independent verification of electrical performance, package pinout compatibility, and compliance certifications before implementation in production designs.
Frequently Asked Questions (FAQ)
Q: Can the PI5A124TEX-1413 be replaced with the PI5A124TEX?
A: Yes, the PI5A124TEX is a parametric equivalent with identical electrical specifications. The difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel) and product lifecycle status. The PI5A124TEX-1413 is preferred for new designs due to Active status.
Q: What determines compatibility between the PI5A124TEX-1413 and cross-manufacturer alternatives?
A: Compatibility is determined by matching the SPDT 2:1 switch configuration, 10Ohm on-state resistance, 2V to 6V supply voltage range, SOT-23-6 package type, and operating temperature range of -40°C to 85°C. All electrical parameters including switching speed, bandwidth, and leakage current must meet or exceed the specified values.
Q: Are there any package pinout differences between substitute parts?
A: The PI5A124TEX maintains identical SOT-23-6 pinout to the PI5A124TEX-1413. Cross-manufacturer alternatives must be individually verified for pinout compatibility, as different manufacturers may assign pins differently despite equivalent functionality.
Q: What is the significance of the Last Time Buy status for the PI5A124TEX?
A: Last Time Buy status indicates that the manufacturer will discontinue production after a specified date. Existing inventory may be available, but future orders cannot be guaranteed. For production designs requiring long-term component availability, the Active status PI5A124TEX-1413 is the appropriate choice.
Q: Does the PI5A124TEX-1413 meet current environmental and regulatory compliance requirements?
A: Yes, the PI5A124TEX-1413 is ROHS3 compliant and REACH unaffected, meeting current environmental regulations for commercial and industrial applications in regulated markets.
