ALD2301SAIL Equivalent & Substitute Parts

Part Overview

The ALD2301SAIL is a general-purpose dual comparator IC manufactured by Advanced Linear Devices Inc., housed in an 8-SOIC surface-mount package. This device features CMOS, NMOS, open-drain, and TTL output configurations, supporting supply voltages from 3V to 12V (single supply) or ±1.5V to ±6V (dual supply). The part is currently active in production with 1007 units in stock and maintains ROHS3 compliance and REACH unaffected status.

Substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required while maintaining functional equivalence within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ALD2301SAIL is determined by the following criteria:

Primary Compatibility Requirements:

• Dual comparator configuration (2 elements)
• General-purpose comparator type
• 8-pin surface-mount package (8-SOIC or 8-TSSOP)
• Supply voltage range overlap with 3V ~ 12V single supply or ±1.5V ~ 6V dual supply
• Output type compatibility (CMOS, open-drain, or TTL capable)
• Active product status
• ROHS3 compliance

Identified Substitute Parts:

Group 1 - Same Manufacturer, Same Package (8-SOIC):

• ALD2301ASAL (Advanced Linear Devices Inc.) - Direct variant with specified electrical characteristics and 0°C ~ 70°C operating temperature

Group 2 - Alternative Manufacturer, Same Package (8-SOIC):

• TS393CDT (STMicroelectronics) - Dual comparator in 8-SOIC with extended supply voltage range (2.7V ~ 16V) and 0°C ~ 70°C operating temperature

Group 3 - Alternative Manufacturer, Alternative Package (8-TSSOP):

• TS393IPT (STMicroelectronics) - Dual comparator in 8-TSSOP with extended supply voltage range (2.7V ~ 16V) and extended operating temperature range (-40°C ~ 125°C)

Parameter Comparison

Engineering Selection Recommendations

ALD2301ASAL Selection Criteria:

• Preferred when maintaining single-manufacturer sourcing from Advanced Linear Devices Inc. is required
• Suitable for applications operating within 0°C to 70°C temperature range
• Identical 8-SOIC package footprint ensures direct PCB compatibility
• Supply voltage range (3V ~ 10V single, ±1.5V ~ 5V dual) is narrower than the main part; verify application requirements fall within this range
• All parts maintain ROHS3 compliance and MSL 1 rating

TS393CDT Selection Criteria:

• Preferred when extended supply voltage range (2.7V ~ 16V) is beneficial
• Maintains identical 8-SOIC package footprint for direct PCB substitution
• Operating temperature range (0°C ~ 70°C) matches ALD2301ASAL
• Output type limited to CMOS and open-drain (no NMOS or TTL); verify application compatibility
• Lower quiescent current (25µA vs. 180µA) may provide power efficiency benefits

TS393IPT Selection Criteria:

• Preferred when extended operating temperature range (-40°C ~ 125°C) is required
• Extended supply voltage range (2.7V ~ 16V) provides design flexibility
• Package change from 8-SOIC to 8-TSSOP requires PCB layout modification; pin-to-pin compatibility must be verified
• Output type limited to CMOS and open-drain; verify application compatibility
• Lower quiescent current (25µA) and input bias current (1pA) support low-power applications

All substitute parts maintain active product status, ROHS3 compliance, and REACH unaffected status, ensuring regulatory and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can ALD2301ASAL be used as a direct replacement for ALD2301SAIL?

A: ALD2301ASAL is compatible within the overlapping supply voltage range (3V ~ 10V single supply, ±1.5V ~ 5V dual supply). The main part specification does not define maximum operating temperature, while ALD2301ASAL is rated 0°C ~ 70°C. Verify your application's temperature requirements and supply voltage range before substitution.

Q: What are the key differences between TS393CDT and TS393IPT?

A: Both are STMicroelectronics TS393 comparators with identical electrical specifications. The primary difference is packaging: TS393CDT uses 8-SOIC while TS393IPT uses 8-TSSOP. TS393IPT also specifies an extended operating temperature range (-40°C ~ 125°C) compared to TS393CDT (0°C ~ 70°C). Package selection depends on PCB layout requirements and temperature environment.

Q: Are there output type compatibility concerns when substituting with TS393 parts?

A: Yes. The ALD2301SAIL supports CMOS, NMOS, open-drain, and TTL outputs. TS393CDT and TS393IPT support only CMOS and open-drain outputs. If your application requires NMOS or TTL output specifically, TS393 parts are not suitable. Verify your circuit's output type requirements before selection.

Q: Can TS393IPT be used in place of TS393CDT?

A: TS393IPT and TS393CDT have identical electrical specifications and both use 8-pin surface-mount packages. TS393IPT offers extended operating temperature range (-40°C ~ 125°C vs. 0°C ~ 70°C). Package footprints differ (8-TSSOP vs. 8-SOIC), requiring PCB layout verification. If temperature range and package compatibility are acceptable, TS393IPT provides broader environmental operating capability.

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

A: The overlapping single-supply voltage range across all parts is 3V ~ 10V. For dual-supply operation, the common range is ±1.5V ~ 5V. Applications requiring supply voltages outside these ranges must use parts with extended specifications (TS393 series supports 2.7V ~ 16V).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. ALD2301ASAL, TS393CDT, and TS393IPT all maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the main part's regulatory status.
