EL5420CS-T13 Equivalent & Substitute Parts

Part Overview

The EL5420CS-T13 is a voltage feedback operational amplifier featuring four independent circuits in a 14-SOIC surface mount package. Manufactured by Renesas Electronics Corporation, this device is classified as a linear amplifier with rail-to-rail output capability. The part is currently listed as obsolete, which necessitates identification of equivalent and substitute components for ongoing design support and production continuity. Active alternatives with identical or enhanced electrical characteristics are available from both Renesas and third-party manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the EL5420CS-T13 are classified into two categories based on electrical and mechanical compatibility:

Parametric Equivalents maintain identical electrical specifications across all critical parameters: amplifier type (voltage feedback), circuit count (4), output type (rail-to-rail), package format (14-SOIC), slew rate (10V/µs), gain bandwidth product (8 MHz), -3dB bandwidth (12 MHz), input bias current (2 nA), input offset voltage (2 mV), supply current (500µA per 4 channels), output current per channel (30 mA), supply voltage range (4.5V to 16.5V), and operating temperature range (-40°C to 125°C). These parts differ only in product status (active versus obsolete) and packaging format (tube versus tape & reel).

Similar Alternatives share the same physical package (14-SOIC), circuit count (4), output type (rail-to-rail), and operating temperature range, but employ different amplifier technology (CMOS versus voltage feedback) and exhibit enhanced electrical performance characteristics including higher slew rate, gain bandwidth product, and output current capability. These parts operate within a narrower supply voltage range and are suitable for applications where improved performance specifications are beneficial.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Parametric Equivalents):

The EL5420CSZ-T13 and EL5420CSZ-T7 are parametric equivalents of the EL5420CS-T13, maintaining identical electrical performance specifications. Both parts are manufactured by Renesas Electronics Corporation and are currently in active product status. The primary distinction between these equivalents is packaging format: EL5420CSZ-T13 is supplied in tape & reel format, while EL5420CSZ-T7 is also supplied in tape & reel format. Both equivalents are ROHS3 compliant, addressing regulatory requirements that the original obsolete part does not meet. The moisture sensitivity level increases from MSL 1 to MSL 3 (168 hours), which requires appropriate handling during storage and assembly operations.

For Enhanced Performance Applications:

The OPA4354AID and OPA4354AIDR, manufactured by Texas Instruments, are similar alternatives that provide enhanced electrical performance within the same 14-SOIC package footprint. These CMOS-based amplifiers deliver 15 times higher slew rate (150V/µs versus 10V/µs), 12.5 times higher gain bandwidth product (100 MHz versus 8 MHz), and 3.3 times higher output current per channel (100 mA versus 30 mA). Both parts are ROHS3 compliant and feature lower moisture sensitivity (MSL 2, 1 year). However, the supply voltage range is restricted to 2.5V to 5.5V, which is narrower than the original part's 4.5V to 16.5V range. Selection of these alternatives is appropriate only when the application supply voltage falls within the 2.5V to 5.5V window and when the enhanced performance characteristics provide functional benefit.

Frequently Asked Questions (FAQ)

Q: Can the EL5420CSZ-T13 be used as a direct replacement for the EL5420CS-T13?

A: Yes. The EL5420CSZ-T13 is a parametric equivalent with identical electrical specifications. The primary differences are product status (active versus obsolete), packaging format (tape & reel versus tube), and regulatory compliance (ROHS3 compliant versus non-compliant). Moisture sensitivity level increases from MSL 1 to MSL 3, requiring compliance with 168-hour storage and handling protocols.

Q: What is the difference between EL5420CSZ-T13 and EL5420CSZ-T7?

A: Both parts are parametric equivalents with identical electrical specifications and regulatory compliance. The designation difference (T13 versus T7) reflects different manufacturing date codes or tape reel specifications. Both are suitable for direct replacement of the EL5420CS-T13.

Q: Can the OPA4354AID replace the EL5420CS-T13 in all applications?

A: The OPA4354AID shares the same 14-SOIC package, circuit count, and operating temperature range, but operates within a narrower supply voltage range (2.5V to 5.5V versus 4.5V to 16.5V). Substitution is valid only when the application supply voltage falls within 2.5V to 5.5V. The OPA4354AID provides enhanced performance characteristics including higher slew rate, gain bandwidth product, and output current capability.

Q: What are the moisture sensitivity implications of switching from EL5420CS-T13 to EL5420CSZ-T13?

A: The EL5420CS-T13 has MSL 1 (unlimited shelf life), while the EL5420CSZ-T13 has MSL 3 (168 hours). MSL 3 classification requires that the component be stored in controlled humidity conditions and used within 168 hours of exposure to ambient conditions exceeding 30% relative humidity. Appropriate moisture barrier packaging and bake-out procedures must be implemented during assembly.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The EL5420CSZ-T13, EL5420CSZ-T7, OPA4354AID, and OPA4354AIDR are all ROHS3 compliant. The original EL5420CS-T13 is RoHS non-compliant, making the compliant alternatives necessary for applications subject to RoHS regulatory requirements.

Q: What is the impact of higher supply current in the OPA4354 series?

A: The OPA4354AID and OPA4354AIDR draw 4.9mA per four channels compared to 500µA per four channels in the EL5420 series. This represents approximately 10 times higher supply current consumption. Applications with strict power budget constraints should retain the EL5420 series equivalents (EL5420CSZ-T13 or EL5420CSZ-T7) rather than transitioning to the OPA4354 series.

Q: Can the EL5420CS-T13 be used in new designs?

A: No. The EL5420CS-T13 is classified as obsolete. New designs must utilize active alternatives: EL5420CSZ-T13, EL5420CSZ-T7 (for parametric equivalence), or OPA4354AID/OPA4354AIDR (for enhanced performance applications with compatible supply voltage ranges).
