LTC2852IMS Equivalent & Substitute Parts

Part Overview

The LTC2852IMS is an active RS422/RS485 transceiver manufactured by Analog Devices Inc., designed for full-duplex communication applications. This interface IC integrates one driver and one receiver pair in a compact 10-MSOP surface mount package. The device operates across a 3V to 3.6V supply range with a maximum data rate of 20Mbps and maintains performance across the industrial temperature range of -40°C to 85°C. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified to provide procurement flexibility, alternative packaging options, and inventory availability across different distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTC2852IMS is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications for protocol support (RS422/RS485), transceiver configuration (1 driver/1 receiver, full-duplex), data rate (20Mbps), supply voltage range (3V to 3.6V), operating temperature range (-40°C to 85°C), receiver hysteresis (25 mV), and physical package dimensions (10-MSOP, 0.118" width, 3.00mm).

The primary distinction between the main part and its substitute is the packaging format. The LTC2852IMS#PBF variant is supplied in tube packaging rather than the standard packaging of the base LTC2852IMS. Both parts share the identical base product number (LTC2852) and are manufactured by Analog Devices Inc. under the same product line.

Substitution is valid when:

• Protocol and transceiver configuration remain unchanged
• Electrical performance parameters are identical
• Physical package footprint is compatible
• Supply voltage and temperature operating ranges match
• RoHS and REACH compliance status is maintained

Parameter Comparison

Engineering Selection Recommendations

Both the LTC2852IMS and LTC2852IMS#PBF are active production parts manufactured by Analog Devices Inc. with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on packaging and inventory requirements rather than electrical or functional differences.

The LTC2852IMS is the standard packaging variant with 2,100 pieces currently in stock. The LTC2852IMS#PBF is supplied in tube packaging with significantly higher inventory availability at 22,522 pieces. Both parts are electrically and mechanically identical, with the same 10-MSOP package footprint suitable for surface mount assembly.

For applications requiring immediate availability or high-volume procurement, the LTC2852IMS#PBF tube-packaged variant provides greater stock depth. For standard procurement workflows, the LTC2852IMS standard packaging is appropriate. The choice between these parts does not affect circuit performance, thermal characteristics, or compliance requirements.

Frequently Asked Questions (FAQ)

Q: Are the LTC2852IMS and LTC2852IMS#PBF electrically identical?

A: Yes. Both parts are manufactured by Analog Devices Inc. and share identical electrical specifications, including protocol support (RS422/RS485), data rate (20Mbps), supply voltage (3V to 3.6V), operating temperature range (-40°C to 85°C), and receiver hysteresis (25 mV).

Q: What is the difference between these two part numbers?

A: The primary difference is packaging format. The LTC2852IMS uses standard packaging, while the LTC2852IMS#PBF is supplied in tube packaging. The physical footprint and pin configuration remain identical.

Q: Can I substitute the LTC2852IMS#PBF for the LTC2852IMS in my design?

A: Yes. The LTC2852IMS#PBF is a direct substitute for the LTC2852IMS. Both parts use the same 10-MSOP package with 0.118" width and 3.00mm dimensions, making them compatible for PCB assembly without design modifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the LTC2852IMS and LTC2852IMS#PBF are ROHS3 compliant and REACH unaffected, meeting environmental regulatory requirements.

Q: Which part should I select for high-volume production?

A: The LTC2852IMS#PBF offers greater inventory availability with 22,522 pieces in stock compared to 2,100 pieces for the standard LTC2852IMS. For high-volume applications, the tube-packaged variant provides better supply chain continuity.

Q: Do these parts have different moisture sensitivity ratings?

A: No. Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What is the operating temperature range for both parts?

A: Both the LTC2852IMS and LTC2852IMS#PBF operate across -40°C to 85°C, suitable for industrial and commercial temperature environments.
