ALD2301ASAL Equivalent & Substitute Parts

Part Overview

The ALD2301ASAL is a dual-channel general-purpose comparator manufactured by Advanced Linear Devices Inc., available in 8-SOIC surface-mount packaging. This active product features CMOS, NMOS, and open-drain TTL output configurations, supporting supply voltages from 3V to 10V (single supply) or ±1.5V to ±5V (dual supply). The device is designed for general-purpose comparison applications requiring low input offset voltage and moderate output current capability. Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical parameter ranges for this comparator category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ALD2301ASAL are qualified based on the following criteria:

• Dual-channel configuration: Both substitute parts contain 2 comparator elements
• Package compatibility: All parts use 8-SOIC surface-mount packaging with identical 0.154" (3.90mm) width
• Output type compatibility: Substitute parts feature open-drain output capability, which is compatible with the ALD2301ASAL's multi-output configuration
• Supply voltage overlap: Substitute parts support voltage ranges that encompass or extend the ALD2301ASAL operating range
• Electrical performance: Input offset voltage, input bias current, and output current specifications fall within acceptable ranges for general-purpose comparator applications
• Compliance alignment: All parts maintain ROHS3 compliance and EAR99 classification

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and ROHS3 compliance, qualifying them for equivalent substitution in general-purpose comparator applications. Selection between NCS3402DR2G and TS393IDT depends on specific application requirements:

The NCS3402DR2G provides extended supply voltage range (2.5V ~ 16V) and operates across industrial temperature range (-40°C ~ 125°C), with minimal quiescent current (640nA) suitable for battery-powered or low-power applications.

The TS393IDT offers superior input bias current performance (1pA @ 5V) and extended dual-supply voltage range (±1.35V ~ 8V), with CMOS output capability matching the ALD2301ASAL's multi-output configuration.

Both substitute parts are available in higher inventory quantities and support extended operating temperature ranges beyond the ALD2301ASAL specification.

Frequently Asked Questions (FAQ)

Q: Can NCS3402DR2G directly replace ALD2301ASAL in all applications?

A: NCS3402DR2G is mechanically and electrically compatible for applications operating within the overlapping supply voltage range (3V ~ 10V). The open-drain output is compatible with the ALD2301ASAL's multi-output configuration. Verify that the reduced typical output current (10mA vs. 60mA) meets application requirements.

Q: What are the key differences between TS393IDT and NCS3402DR2G?

A: TS393IDT provides superior input bias current (1pA @ 5V) and includes CMOS output capability. NCS3402DR2G offers lower quiescent current (640nA) and extended supply voltage range. Both use identical 8-SOIC packaging and support extended temperature operation.

Q: Are all substitute parts available in the same packaging options?

A: All three parts use 8-SOIC surface-mount packaging with identical dimensions (0.154", 3.90mm width). Packaging format differs: ALD2301ASAL is supplied in Tube, NCS3402DR2G in Tape & Reel, and TS393IDT in Cut Tape & Digi-Reel. These differences do not affect electrical compatibility.

Q: Do substitute parts maintain the same compliance certifications?

A: All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. Moisture sensitivity level is 1 (Unlimited) for all three parts, ensuring equivalent handling and storage requirements.

Q: What supply voltage range is common to all three parts?

A: The overlapping single-supply range is 3V ~ 10V. For dual-supply applications, the ALD2301ASAL range (±1.5V ~ ±5V) is supported by TS393IDT (±1.35V ~ ±8V) but not by NCS3402DR2G, which operates single-supply only.
