FSAV430MTC Equivalent & Substitute Parts

Part Overview

The FSAV430MTC is a quad 2:1 video switch IC manufactured by onsemi in a 16-TSSOP package. This component functions as a bi-directional video multiplexer/demultiplexer with RGB capability, designed for video signal routing applications. The part is currently obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Substitute parts must maintain functional compatibility across switching architecture, channel configuration, and electrical performance within specified operating ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory criteria:

Core Functional Requirements:

• Switch circuit type: SPDT (Single-Pole Double-Throw)
• Multiplexer/Demultiplexer configuration: 2:1
• Number of channels: 4
• Operating temperature range: -40°C ~ 85°C (TA)
• Mounting type: Surface Mount

Electrical Compatibility Criteria:

• Supply voltage range must encompass or overlap with 3V ~ 3.6V
• On-state resistance must not exceed 6Ω maximum
• -3dB bandwidth must meet or exceed 1.1GHz for video applications

Package Compatibility:

• 16-pin package variants (16-TSSOP, 16-SSOP, 16-QSOP) are mechanically compatible with appropriate PCB layout adjustments

Substitutes are grouped by product status (Active vs. Last Time Buy) and packaging format to facilitate procurement decisions.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: TS3A5018PWR

TS3A5018PWR is the preferred substitute for FSAV430MTC. It maintains identical 16-TSSOP packaging, matching PCB footprint without layout modification. Product status is Active with full manufacturing support and ROHS3 compliance. Supply voltage range (1.65V ~ 3.6V) encompasses the original 3V ~ 3.6V specification. On-state resistance of 10Ω exceeds the original 6Ω specification but remains within acceptable limits for video switching applications. Bandwidth of 300MHz supports video signal integrity, though lower than the original 1.1GHz specification.

Secondary Recommendation: TS3L110PWR

TS3L110PWR provides Active product status with identical 16-TSSOP packaging. Supply voltage range (3V ~ 3.6V) matches the original specification exactly. On-state resistance of 8Ω is closer to the original 6Ω specification. Bandwidth of 500MHz provides improved performance margin for video applications. This part is optimized for networking applications (10/100 Base-T) and maintains full ROHS3 compliance.

Alternative for Cost-Sensitive Applications: PI5A100QEX

PI5A100QEX offers Active product status with highest inventory availability (17,142 pcs). Packaging is 16-QSOP, requiring PCB layout adjustment. Supply voltage range (2V ~ 6V) provides broader operating margin. On-state resistance of 10Ω and bandwidth of 230MHz are functional but represent lower performance margins compared to primary recommendations.

End-of-Life Consideration: TS3A5018PW

TS3A5018PW maintains identical 16-TSSOP packaging and electrical specifications matching TS3A5018PWR but carries Last Time Buy status. This part should be selected only when existing inventory commitments require it.

Frequently Asked Questions (FAQ)

Q: Can PI5A100QEX be used as a direct replacement without PCB modification?

A: No. PI5A100QEX uses 16-QSOP packaging versus the original 16-TSSOP. While both are 16-pin packages, pin pitch and body dimensions differ. PCB layout modification is required. TS3A5018PWR and TS3L110PWR maintain identical 16-TSSOP packaging for direct substitution.

Q: Why does TS3A5018PWR have higher on-state resistance (10Ω) than FSAV430MTC (6Ω)?

A: On-state resistance variation reflects different semiconductor process technology between manufacturers. The 10Ω specification remains within acceptable limits for video switching applications where signal integrity is maintained through proper impedance matching and signal conditioning.

Q: Is the 300MHz bandwidth of TS3A5018PWR sufficient for video applications?

A: Yes. The 300MHz bandwidth of TS3A5018PWR supports standard video signal frequencies including composite video, component video, and RGB signals. The original 1.1GHz specification provides additional margin but is not required for typical video switching applications.

Q: What is the difference between TS3A5018PWR and TS3A5018PW?

A: Both parts are electrically identical with 16-TSSOP packaging. TS3A5018PWR is Active status with Cut Tape & Digi-Reel packaging (109,400 pcs inventory). TS3A5018PW is Last Time Buy status with Tube packaging (1,220 pcs inventory). TS3A5018PWR is recommended for new designs.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All active substitute parts (PI5A100QEX, TS3A5018DBQR, TS3A5018PWR, TS3L110PWR) carry ROHS3 compliance certification. The original FSAV430MTC does not specify RoHS status due to obsolete product classification.

Q: Can TS3L110PWR be used in general video applications or only networking?

A: TS3L110PWR is optimized for networking applications (10/100 Base-T) but functions as a general-purpose 4-channel 2:1 switch. It meets all core switching requirements and can be used in video applications. The networking optimization provides additional performance margin for high-frequency signal integrity.
