Key Parameters

Substitute Part Grouping Explanation

Substitution of the FSAV330MTCX is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Multiplexer/Demultiplexer Circuit: 2:1
• Switch Circuit: SPDT
• Number of Channels: 4
• Operating Temperature: -40°C ~ 85°C (TA)
• Mounting Type: Surface Mount
• RoHS Status: ROHS3 Compliant

Voltage Supply Compatibility: The FSAV330MTCX operates at 4V ~ 5.5V single supply. Substitutes are grouped into two voltage classes:

• 5V Class (Direct Voltage Match): TS5V330CPWR, TS5V330DBQR, TS5V330PW — operate at 4V ~ 5.5V
• 3V Class (Voltage Incompatible): TS3V330DBQR, TS3V330DGVR, TS3V330PW, TS3V330PWR, TS3V340DBQR, TS3V340PW, TS3V340PWR — operate at 3V ~ 3.6V and are not suitable for direct replacement in 5V circuits

Package Compatibility:

• 16-TSSOP (0.173", 4.40mm Width): TS3V330PW, TS3V330PWR, TS3V340PW, TS3V340PWR, TS5V330CPWR, TS5V330PW
• 16-TVSOP (0.173", 4.40mm Width): TS3V330DGVR
• 16-SSOP (0.154", 3.90mm Width): TS3V330DBQR, TS3V340DBQR, TS5V330DBQR

Bandwidth and On-State Resistance:

• 300MHz bandwidth with 10Ohm on-state resistance: TS5V330CPWR, TS5V330DBQR, TS5V330PW
• 300MHz bandwidth with 10Ohm on-state resistance: TS3V330DBQR, TS3V330DGVR, TS3V330PW, TS3V330PWR
• 500MHz bandwidth with 6Ohm on-state resistance: TS3V340DBQR, TS3V340PW, TS3V340PWR (enhanced performance)

Parameter Comparison

Engineering Selection Recommendations

For Direct Voltage-Compatible Substitution (4V ~ 5.5V Supply):

TS5V330CPWR is the primary active substitute. It maintains identical voltage supply range (4V ~ 5.5V), on-state resistance (10Ohm), and operating temperature specifications. The 16-TSSOP package matches the original footprint. Product status is Active, ensuring long-term availability and supply chain stability.

TS5V330DBQR provides equivalent electrical performance with 300MHz minimum bandwidth specification. However, the 16-SSOP package (0.154" width) differs from the original 16-TSSOP (0.173" width), requiring PCB layout modification. Product status is Last Time Buy, indicating limited future availability.

TS5V330PW offers identical package and electrical specifications but carries Last Time Buy status, restricting its use to legacy production or short-term applications.

For 3V Supply Circuits (Not Compatible with Original 5V Specification):

TS3V330PWR and TS3V330DGVR are active components with matching 300MHz bandwidth and 10Ohm on-state resistance. These operate at 3V ~ 3.6V and are suitable only for circuits redesigned for lower voltage operation. TS3V330PWR uses the 16-TSSOP package; TS3V330DGVR uses 16-TVSOP.

TS3V340PWR and TS3V340DBQR provide enhanced performance with 500MHz bandwidth and 6Ohm on-state resistance, also at 3V ~ 3.6V supply. These are applicable to designs requiring higher bandwidth specifications.

Compliance and Certification:

All listed substitutes maintain ROHS3 compliance and EAR99 export classification, matching the original part's regulatory status. Moisture sensitivity levels vary between MSL 1 (Unlimited) and MSL 2 (1 Year), affecting storage and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can TS3V330PWR or TS3V340PWR directly replace FSAV330MTCX in a 5V circuit?

A: No. The TS3V330 and TS3V340 series operate at 3V ~ 3.6V supply voltage, while FSAV330MTCX requires 4V ~ 5.5V. Direct substitution will result in circuit malfunction or component damage. These parts are suitable only for circuits redesigned for 3V operation.

Q: What is the difference between TS5V330CPWR and TS5V330DBQR?

A: Both operate at 4V ~ 5.5V with 10Ohm on-state resistance. TS5V330CPWR uses 16-TSSOP packaging (0.173" width) matching the original footprint and is Active status. TS5V330DBQR uses 16-SSOP packaging (0.154" width), requiring PCB modification, and carries Last Time Buy status. For new designs, TS5V330CPWR is preferred.

Q: Why do TS3V340 parts have lower on-state resistance (6Ohm vs 10Ohm)?

A: The TS3V340 series represents an enhanced performance variant with 500MHz bandwidth compared to 300MHz in TS3V330 series. The reduced on-state resistance is a characteristic of this higher-performance design. These parts are not interchangeable with FSAV330MTCX due to voltage incompatibility.

Q: Are there package compatibility concerns when substituting FSAV330MTCX?

A: Yes. The original part uses 16-TSSOP (0.173", 4.40mm width). Substitutes using 16-SSOP (0.154", 3.90mm width) require PCB layout changes. For minimal redesign, select substitutes in matching 16-TSSOP packaging: TS5V330CPWR, TS5V330PW, TS3V330PW, TS3V330PWR, TS3V340PW, or TS3V340PWR.

Q: What does "Last Time Buy" product status mean for component selection?

A: Last Time Buy indicates the manufacturer will cease production after a specified date. Parts with this status (TS3V330PW, TS5V330DBQR, TS5V330PW) should be avoided for new designs requiring long-term supply. Select Active status components (TS5V330CPWR, TS3V330PWR, TS3V340PWR) for ongoing production.

Q: How do moisture sensitivity levels affect handling?

A: FSAV330MTCX and most substitutes carry MSL 1 (Unlimited), allowing indefinite shelf life under controlled conditions. TS3V330DBQR and TS3V340DBQR carry MSL 2 (1 Year), requiring reflow within one year of moisture exposure. Storage in dry conditions or desiccant packaging is mandatory for MSL 2 components.
