FSAV430MTCX Equivalent & Substitute Parts

Part Overview

The FSAV430MTCX is a quad 2:1 video switch IC manufactured by onsemi in 16-TSSOP packaging. This component functions as a bidirectional RGB video multiplexer/demultiplexer with four independent SPDT switch circuits. The device is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing production support. Alternative components must maintain functional compatibility across video switching applications while meeting the same electrical and mechanical specifications.

Engineering Selection Recommendations

Preferred Substitutes (Active Product Status):

TS3A5018PWR is the primary recommended substitute. This Texas Instruments component maintains the 16-TSSOP package format, active product status, unlimited MSL rating, and meets all functional requirements for quad 2:1 SPDT switching. The device operates within the 1.65V ~ 3.6V supply range, encompassing the FSAV430MTCX specification of 3V ~ 3.6V.

PI5A100QEX from Diodes Incorporated provides an active alternative with extended supply voltage range (2V ~ 6V) and higher inventory availability. The 16-QSOP package requires PCB layout modification but maintains electrical compatibility.

TS3L110PWR offers active status with 500MHz bandwidth suitable for networking applications. The 3V ~ 3.6V supply range matches the original specification exactly.

Secondary Substitutes (Last Time Buy Status):

TS3A5018PW and TS5V330PW are available but classified as Last Time Buy, indicating limited future availability. These components are suitable for immediate replacement but not recommended for long-term production planning.

Package Considerations:

Direct 16-TSSOP package compatibility exists with TS3A5018PWR, TS3A5018PW, TS3L110PWR, TS3L110PW, and TS5V330PW. Alternative packages (16-QSOP for PI5A100QEX, 16-SSOP for TS3A5018DBQR) require PCB redesign and are recommended only when 16-TSSOP alternatives are unavailable.

Compliance Status:

All substitute parts maintain ROHS3 compliance and EAR99 ECCN classification, matching the original component's regulatory status.

Frequently Asked Questions (FAQ)

Q: Can TS3A5018PWR directly replace FSAV430MTCX without PCB modification?

A: Yes. Both components use 16-TSSOP packaging with identical pin counts and functional configuration (quad 2:1 SPDT switches). The supply voltage range of TS3A5018PWR (1.65V ~ 3.6V) encompasses the FSAV430MTCX requirement (3V ~ 3.6V). No PCB layout changes are required.

Q: What is the difference between TS3A5018PWR and TS3A5018PW?

A: Both are Texas Instruments TS3A5018 variants in 16-TSSOP packaging with identical electrical specifications. TS3A5018PWR is Active status with Cut Tape & Digi-Reel packaging (109,400 units in stock). TS3A5018PW is Last Time Buy status with Tube packaging (1,220 units in stock). TS3A5018PWR is recommended for new designs.

Q: Why does PI5A100QEX have lower -3dB bandwidth (230MHz) compared to FSAV430MTCX (1.1GHz)?

A: PI5A100QEX is specified for general-purpose switching applications with 230MHz bandwidth, while FSAV430MTCX targets high-speed video applications requiring 1.1GHz bandwidth. PI5A100QEX is suitable for standard video switching but not for high-frequency video formats. Bandwidth selection depends on application requirements.

Q: Can I use TS3L110PWR as a substitute for video applications?

A: TS3L110PWR is designed for networking (10/100 Base-T Ethernet) applications with 500MHz bandwidth. While it meets the 2:1 SPDT quad switch configuration, it is optimized for Ethernet switching rather than RGB video. Use TS3A5018PWR or TS5V330PW for video applications.

Q: What does MSL 2 (1 Year) on TS3A5018DBQR mean for handling?

A: MSL 2 indicates the component requires reflow soldering within one year of package opening. FSAV430MTCX and most substitutes have MSL 1 (Unlimited), allowing indefinite shelf life after opening. TS3A5018DBQR requires stricter moisture control and storage protocols.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original FSAV430MTCX specification. All components are REACH Unaffected and classified as EAR99 for export purposes.

Q: Which substitute has the best inventory availability?

A: TS3A5018PWR has the highest inventory (109,400 units) with Active product status. PI5A100QEX is also well-stocked (17,142 units). Both are suitable for immediate procurement.
