TLV4313IPWR Equivalent & Substitute Parts
Part Overview
The TLV4313IPWR is a general-purpose operational amplifier manufactured by Texas Instruments, configured as a 4-circuit rail-to-rail amplifier in a 14-TSSOP surface-mount package. This device is classified as Active product status and is designed for low-voltage, low-power applications requiring multiple amplifier channels in a compact form factor.
Substitute parts are necessary when the TLV4313IPWR becomes unavailable, when alternative performance characteristics better suit specific application requirements, or when supply chain optimization requires component standardization across product lines. All substitute parts listed maintain the same package type (14-TSSOP), circuit count (4 channels), and output configuration (rail-to-rail) as the primary device.

Engineering Selection Recommendations
Direct Substitutes (Minimum Performance Impact):
The NCS20084DTBR2G (onsemi) and MCP6L04T-E/ST (Microchip) provide the closest electrical alignment to the TLV4313IPWR. Both devices maintain the 1 pA input bias current specification, operate within the 1.8 V to 5.5 V supply range, and deliver comparable slew rate and bandwidth characteristics. The NCS20084DTBR2G carries AEC-Q100 automotive qualification, while the MCP6L04T-E/ST offers extended supply voltage tolerance to 6 V maximum.
Performance-Enhanced Substitutes:
The MCP6274-E/ST and MCP6274T-E/ST (Microchip) provide increased gain bandwidth product (2 MHz versus 1 MHz) and improved slew rate (0.9 V/µs versus 0.5 V/µs), suitable for applications requiring higher frequency response. These devices maintain 1 pA input bias current and operate across the full -40°C to 125°C temperature range.
The TS1874IPT and TS1874IYPT (STMicroelectronics) deliver enhanced output current capability (80 mA per channel versus 15 mA) and higher gain bandwidth product (1.8 MHz), with the IYPT variant offering AEC-Q100 automotive qualification.
Lower-Performance Alternatives:
The TS1854IPT (STMicroelectronics) operates with reduced gain bandwidth product (630 kHz) and slew rate (0.25 V/µs), suitable only for applications with relaxed frequency response requirements.
Compliance Considerations:
All substitute parts maintain ROHS3 compliance and REACH unaffected status. Automotive applications requiring AEC-Q100 qualification should select NCS20084DTBR2G, LMV324IYPT, or TS1874IYPT.
Frequently Asked Questions (FAQ)
Q: Can the TLV4313IPWR be directly replaced with any of these substitute parts on the PCB?
A: Yes. All substitute parts are housed in the 14-TSSOP surface-mount package with identical pin configuration and rail-to-rail 4-channel architecture. Direct PCB substitution is mechanically and electrically feasible. However, application-specific performance requirements must be evaluated against the electrical parameter differences listed in the comparison table.

Q: Which substitute part has the lowest input offset voltage?
A: The LMV324IPT and LMV324IYPT specify 100 µV input offset voltage, compared to 750 µV for the TLV4313IPWR. These devices are suitable for precision analog applications requiring minimal offset drift.
Q: Can the TLV4313IPWR be used in applications requiring higher bandwidth?
A: The MCP6274-E/ST and MCP6274T-E/ST provide 2 MHz gain bandwidth product (versus 1 MHz for the TLV4313IPWR) and 0.9 V/µs slew rate, supporting higher-frequency signal processing requirements.
Q: What is the moisture sensitivity level (MSL) difference between the main part and substitutes?
A: The TLV4313IPWR specifies MSL 2 (1 Year shelf life). All substitute parts specify MSL 1 (Unlimited shelf life), providing extended storage capability and reduced moisture-related handling requirements.
Q: Are all substitute parts available in the same packaging options as the TLV4313IPWR?
A: All substitute parts are available in 14-TSSOP surface-mount packaging. Packaging format variations (Cut Tape, Tape & Reel, Tube) differ by manufacturer and part number suffix but do not affect electrical or mechanical compatibility.
