Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TS321IDR are identified based on strict electrical and mechanical compatibility criteria. The primary substitution logic is governed by the following parameters:

Package Compatibility: The substitute part must use the 8-SOIC surface mount package with 0.154" (3.90mm) width to ensure mechanical fit on existing PCB layouts.

Supply Voltage Range: The substitute must operate within or encompass the TS321IDR supply voltage range of 3V to 30V. Devices with wider or equivalent supply ranges are acceptable.

Output Current Capability: The substitute must deliver at least 40 mA per output channel to maintain functional equivalence in driving loads.

Compliance Requirements: Both the main part and substitute must maintain ROHS3 compliance and MSL Level 1 rating to ensure environmental and manufacturing process compatibility.

Product Status: Active product status ensures long-term availability and supply chain reliability.

The LT1252CS8#PBF from Analog Devices Inc. meets these substitution criteria through equivalent package geometry, compatible supply voltage specifications, and superior output current capability.

Parameter Comparison

Engineering Selection Recommendations

Mechanical Compatibility: Both the TS321IDR and LT1252CS8#PBF utilize identical 8-SOIC package geometry (0.154" width, 3.90mm), ensuring direct PCB footprint compatibility without layout modifications.

Electrical Compatibility: The LT1252CS8#PBF operates within the TS321IDR supply voltage envelope and exceeds minimum output current requirements (55 mA versus 40 mA specified). The substitute part supports both single supply (4V to 28V) and dual supply (±2V to ±14V) configurations, providing operational flexibility.

Regulatory Compliance: Both parts maintain ROHS3 compliance and MSL Level 1 rating, satisfying environmental and manufacturing process requirements. Both devices carry EAR99 ECCN classification and REACH Unaffected status.

Product Availability: Both the TS321IDR and LT1252CS8#PBF maintain active product status, ensuring continued supply chain access and technical support.

Supply Current Consideration: The LT1252CS8#PBF exhibits higher supply current consumption (8.5 mA versus 600 µA). Circuit designs must accommodate this increased power draw in power budget calculations.

Frequently Asked Questions (FAQ)

Q: Can the LT1252CS8#PBF directly replace the TS321IDR without PCB modifications?

A: Yes. Both devices use identical 8-SOIC package geometry with 0.154" (3.90mm) width. Pin-to-pin footprint compatibility is maintained, allowing direct substitution on existing PCB layouts without physical modifications.

Q: What are the key electrical differences between these parts?

A: The LT1252CS8#PBF provides significantly higher slew rate (125 V/µs versus 0.4 V/µs) and greater output current capability (55 mA versus 40 mA). The substitute part consumes higher supply current (8.5 mA versus 600 µA). These differences reflect the LT1252CS8#PBF's design for video and current feedback applications versus the TS321IDR's general-purpose amplifier architecture.

Q: Are both parts compliant with environmental and regulatory standards?

A: Yes. Both the TS321IDR and LT1252CS8#PBF are ROHS3 compliant, carry MSL Level 1 rating, and are REACH Unaffected. Both devices are classified as EAR99 for export control purposes.

Q: What supply voltage configurations are supported?

A: The TS321IDR operates with single supply from 3V to 30V. The LT1252CS8#PBF supports single supply (4V to 28V) and dual supply (±2V to ±14V) configurations. The substitute part's minimum single supply voltage is 4V, which is above the TS321IDR's 3V minimum.

Q: How do the packaging options differ?

A: The TS321IDR is supplied in Tape & Reel (TR) packaging. The LT1252CS8#PBF is supplied in Tube packaging. Both use identical 8-SOIC case geometry. Packaging format does not affect electrical or mechanical compatibility.

Q: What is the operating temperature range for each part?

A: The TS321IDR operates from -40°C to 125°C. Operating temperature specifications for the LT1252CS8#PBF were not provided in the available technical parameters.
