ISL43L210IH-T Equivalent & Substitute Parts

Part Overview

The ISL43L210IH-T is a single-circuit SPDT (Single Pole Double Throw) analog switch manufactured by Renesas Electronics Corporation, housed in a 6-pin SC-70 package. This component features a 360mOhm typical on-state resistance and operates across a 1.1V to 4.5V single supply voltage range, making it suitable for low-voltage signal routing and multiplexing applications.

The ISL43L210IH-T carries an Obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and access components with improved specifications or active manufacturing status.

Substitute Part Grouping Explanation

Substitution eligibility for the ISL43L210IH-T is determined by the following critical parameters:

Mandatory Compatibility Criteria:

Switch circuit type: SPDT
Multiplexer configuration: 2:1
Number of circuits: 1
Package compatibility: 6-TSSOP, SC-88, SOT-363
Operating temperature range: -40°C ~ 85°C minimum

Performance Tolerance Parameters:

On-state resistance must not exceed application requirements
Supply voltage range must encompass the design operating point
Switch timing (Ton, Toff) must meet signal routing speed requirements
Leakage current specifications must satisfy low-power constraints

Substitute parts are grouped into three categories:

Direct Equivalents (Packaging Variants): Parts with identical electrical specifications but different packaging or tape/reel configurations. These are interchangeable at the functional level.

Parametric Equivalents (Enhanced Specifications): Parts with superior or equivalent electrical performance within the same functional class. These offer improved characteristics such as lower on-state resistance, faster switching, or lower leakage current.

Similar Alternatives (Performance Trade-offs): Parts with different on-state resistance or other parameter variations that may require circuit re-evaluation but maintain core SPDT 2:1 functionality.

Engineering Selection Recommendations

Primary Recommendation: ISL43L210IHZ-T or ISL43L210IHZ-T7A

These Renesas parts are direct electrical equivalents to the ISL43L210IH-T with identical specifications. Both are in Active product status and ROHS3 compliant, addressing the obsolescence and compliance limitations of the original part. ISL43L210IHZ-T is available in Cut Tape and Digi-Reel packaging, while ISL43L210IHZ-T7A is supplied in Tape & Reel format. Selection between these variants depends on procurement and assembly requirements.

Secondary Recommendation: TS5A9411DCKR (Texas Instruments)

This part offers superior performance characteristics including significantly lower on-state resistance (9Ohm vs. 360mOhm), faster switching times, and lower leakage current (500pA vs. 30nA). It maintains Active product status and ROHS3 compliance. The supply voltage range (2.25V ~ 5.5V) is compatible with most applications using the ISL43L210IH-T. This option is suitable for designs where improved signal integrity and lower power consumption are beneficial.

Alternative Consideration: NC7SB3157P6X (onsemi)

This part provides low on-state resistance (15Ohm) and fast switching performance with Active product status and ROHS3 compliance. The wider supply voltage range (1.65V ~ 5.5V) accommodates extended operating conditions. This option is appropriate for applications requiring improved analog signal fidelity.

Not Recommended: NLASTV4599DFT2G, TS5A4624DCKT, TS5A9411DCKT, PI5A4599BCEX

These parts carry Obsolete or Last Time Buy product status, which does not resolve the supply continuity issue presented by the ISL43L210IH-T obsolescence.

Frequently Asked Questions (FAQ)

Q: Can I directly replace ISL43L210IH-T with ISL43L210IHZ-T?

A: Yes. Both parts are electrically identical with matching on-state resistance (360mOhm), supply voltage range (1.1V ~ 4.5V), switching times, and leakage specifications. The primary difference is packaging format and compliance status. ISL43L210IHZ-T is ROHS3 compliant and in Active production status.

Q: What is the difference between ISL43L210IHZ-T and ISL43L210IHZ-T7A?

A: Both parts have identical electrical specifications. The difference is packaging: ISL43L210IHZ-T is supplied in Cut Tape and Digi-Reel format, while ISL43L210IHZ-T7A is supplied in Tape & Reel format. Selection depends on your assembly process and procurement preferences.

Q: Can I use TS5A9411DCKR as a drop-in replacement?

A: TS5A9411DCKR is functionally compatible as a SPDT 2:1 switch in the same SC-70-6 package. However, it has significantly different electrical characteristics: 9Ohm on-state resistance versus 360mOhm, and a higher minimum supply voltage (2.25V vs. 1.1V). Circuit re-evaluation is required to confirm compatibility with your specific application, particularly regarding signal attenuation and power supply constraints.

Q: Why do some substitute parts have lower on-state resistance?

A: Lower on-state resistance reduces signal attenuation and power dissipation in analog switching applications. Parts like TS5A9411DCKR (9Ohm) and NC7SB3157P6X (15Ohm) represent newer technology generations with improved performance. If your application can tolerate the higher minimum supply voltage, these parts offer superior signal integrity.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts (ISL43L210IHZ-T, ISL43L210IHZ-T7A, TS5A9411DCKR, NC7SB3157P6X) are ROHS3 compliant. The original ISL43L210IH-T is RoHS non-compliant. If RoHS compliance is a design requirement, the Renesas direct equivalents or Texas Instruments alternatives are appropriate selections.

Q: What is the impact of different leakage current specifications?

A: Leakage current affects power consumption in low-power or battery-operated designs. The ISL43L210IH-T specifies 30nA maximum leakage. TS5A9411DCKR offers superior performance at 500pA, while NC7SB3157P6X and NLASTV4599DFT2G specify 100nA. For applications with strict power budgets, lower leakage specifications are advantageous.

Q: Can I use parts with different supply voltage ranges?

A: Substitute parts must support your design's operating supply voltage. The ISL43L210IH-T operates from 1.1V to 4.5V. TS5A9411DCKR requires a minimum of 2.25V, which may not be suitable for ultra-low-voltage applications. NC7SB3157P6X (1.65V ~ 5.5V) and PI5A4599BCEX (1.6V ~ 6V) offer broader compatibility. Verify that the substitute part's voltage range encompasses your application's operating point.

Q: What packaging options are available?

A: All substitute parts are available in 6-pin surface-mount packages compatible with SC-70-6, SC-88, or SOT-363 footprints. Packaging variants (Cut Tape, Digi-Reel, Tape & Reel) affect procurement and assembly processes but do not impact electrical performance. Confirm your assembly equipment compatibility with the selected packaging format.
