Substitute Part Grouping Explanation

Substitution of the MAX4123EUA is determined by equivalence in the following critical parameters: amplifier type (general purpose), number of circuits (1), output type (rail-to-rail), supply voltage range compatibility, operating temperature range, and surface mount package compatibility.

Primary Substitution Criteria:

Amplifier Type: General Purpose
Number of Circuits: 1
Output Type: Rail-to-Rail
Voltage - Supply Span (Min): ≥ 2.7 V
Voltage - Supply Span (Max): ≤ 6.5 V
Mounting Type: Surface Mount
Package compatibility: 8-pin surface mount configurations

The substitute parts are grouped into two categories: direct manufacturer variants and cross-manufacturer alternatives. Direct variants maintain identical electrical specifications and base product lineage. Cross-manufacturer alternatives provide equivalent functional performance within the specified parameter ranges.

Engineering Selection Recommendations

MAX4123EUA+ (Direct Manufacturer Variant)

The MAX4123EUA+ is the active production equivalent of the obsolete MAX4123EUA, manufactured by Analog Devices Inc./Maxim Integrated. This part maintains identical electrical specifications and package configuration while offering ROHS3 compliance. Selection of MAX4123EUA+ is appropriate for applications requiring direct functional equivalence with improved regulatory compliance. Packaging is supplied in Tube format.

TLV2460AQPWRG4Q1 (Cross-Manufacturer Alternative)

The TLV2460AQPWRG4Q1, manufactured by Texas Instruments, provides cross-manufacturer substitution with enhanced performance characteristics. This part features higher gain bandwidth product (6.4 MHz versus 5 MHz), lower input bias current (1.3 nA versus 50 nA), higher output current capability (80 mA versus 50 mA), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). The device carries Automotive grade qualification and AEC-Q100 certification. Package width differs (4.40mm versus 3.00mm), requiring PCB layout verification. Packaging is supplied in Tape & Reel format. Product status is Active.

TLV2460QPWRG4Q1 (Cross-Manufacturer Alternative)

The TLV2460QPWRG4Q1, manufactured by Texas Instruments, provides equivalent cross-manufacturer substitution with identical electrical specifications to TLV2460AQPWRG4Q1. This part carries Automotive grade qualification and AEC-Q100 certification. Product status is Active. Package width differs (4.40mm versus 3.00mm), requiring PCB layout verification.

Frequently Asked Questions (FAQ)

Q: Can MAX4123EUA+ be used as a direct replacement for MAX4123EUA?

A: Yes. MAX4123EUA+ maintains identical electrical specifications, circuit configuration, and pin assignment. The primary difference is product status (Active versus Obsolete) and RoHS compliance (ROHS3 Compliant versus RoHS non-compliant). Packaging format differs (Tube versus unspecified), which may affect procurement and assembly processes.

Q: What are the key differences between MAX4123EUA and TLV2460 series parts?

A: The TLV2460 series offers higher gain bandwidth product (6.4 MHz versus 5 MHz), significantly lower input bias current (1.3 nA versus 50 nA), higher output current per channel (80 mA versus 50 mA), and extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). Maximum supply voltage is reduced from 6.5 V to 6 V. Package width increases from 3.00mm to 4.40mm, requiring PCB layout verification.

Q: Are TLV2460 parts suitable for automotive applications?

A: TLV2460AQPWRG4Q1 and TLV2460QPWRG4Q1 carry Automotive grade designation and AEC-Q100 qualification. TLV2460QPWG4 does not carry automotive qualification. Verify application requirements before selection.

Q: What is the impact of package width difference between MAX4123EUA and TLV2460 series?

A: MAX4123EUA uses 8-TSSOP/8-MSOP with 3.00mm width. TLV2460 series uses 8-TSSOP with 4.40mm width. This difference requires PCB footprint modification and layout verification. Pin pitch and electrical connections remain compatible.

Q: Which substitute part offers the best long-term availability?

A: MAX4123EUA+ and TLV2460AQPWRG4Q1 and TLV2460QPWRG4Q1 all carry Active product status. TLV2460QPWG4 is Discontinued at DiGi Electronics and should not be selected for new designs requiring long-term supply assurance.

Q: Are all substitute parts RoHS compliant?

A: MAX4123EUA is RoHS non-compliant. MAX4123EUA+, TLV2460AQPWRG4Q1, TLV2460QPWG4, and TLV2460QPWRG4Q1 are all ROHS3 Compliant.

Q: What supply voltage range must be verified when substituting with TLV2460 series?

A: MAX4123EUA operates from 2.7 V to 6.5 V. TLV2460 series operates from 2.7 V to 6 V. Applications requiring supply voltages above 6 V are not compatible with TLV2460 substitutes.
