ADM3310EARU Equivalent & Substitute Parts

Part Overview

The ADM3310EARU is a full-duplex RS232 transceiver interface IC manufactured by Analog Devices Inc., configured with 3 drivers and 5 receivers in a 28-TSSOP surface mount package. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ADM3310EARU is determined by strict equivalence across the following parameters:

• RS232 protocol implementation
• 3 driver / 5 receiver configuration
• Full-duplex operation capability
• 460 Kbps data rate support
• 2.7V to 3.6V supply voltage range
• -40°C to 85°C operating temperature range
• 140 mV receiver hysteresis specification
• 28-TSSOP package and surface mount compatibility
• MSL 1 moisture sensitivity rating

The ADM3310EARUZ and ADM3311EARUZ meet all electrical and mechanical substitution criteria. Both parts are manufactured by Analog Devices Inc. and maintain identical functional specifications. The primary distinction is product status: ADM3310EARUZ shares the same base product number as the obsolete ADM3310EARU, while ADM3311EARUZ represents an alternative base product line with equivalent performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both ADM3310EARUZ and ADM3311EARUZ are qualified substitutes for the obsolete ADM3310EARU based on complete electrical and mechanical parameter equivalence. Selection between the two active alternatives should be based on the following factors:

ADM3310EARUZ maintains the same base product number (ADM3310) as the original obsolete part, providing direct lineage continuity for design documentation and supply chain traceability.

ADM3311EARUZ represents an alternative base product line (ADM3311) with identical functional specifications and compliance certifications. This option may offer superior long-term availability and supply stability.

Both substitute parts carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Both are supplied in tube packaging and maintain MSL 1 moisture sensitivity rating, ensuring compatibility with standard handling and storage procedures.

Frequently Asked Questions (FAQ)

Q: Can ADM3310EARUZ and ADM3311EARUZ be used interchangeably with ADM3310EARU?

A: Yes. Both parts maintain identical electrical specifications including RS232 protocol, 3/5 driver/receiver configuration, 460 Kbps data rate, 2.7V to 3.6V supply voltage range, and -40°C to 85°C operating temperature. Both are packaged in 28-TSSOP surface mount configuration with matching pin assignments and functional behavior.

Q: What is the primary difference between ADM3310EARUZ and ADM3311EARUZ?

A: The base product number differs (ADM3310 versus ADM3311), but all electrical and mechanical specifications are identical. Both are active products with ROHS3 compliance and REACH unaffected status. Selection may be based on supply availability and long-term sourcing strategy.

Q: Are there any compliance or certification differences between the substitute parts and the original?

A: The substitute parts (ADM3310EARUZ and ADM3311EARUZ) carry explicit ROHS3 compliance and REACH unaffected certifications. The original ADM3310EARU does not specify these certifications in the provided data. Both substitutes meet current regulatory requirements for electronic component manufacturing and distribution.

Q: Is the 28-TSSOP package identical across all three parts?

A: Yes. All three parts use the 28-TSSOP package with 0.173" width and 4.40mm body dimension. Surface mount compatibility and PCB footprint requirements are identical, enabling direct board-level substitution without layout modifications.

Q: What is the moisture sensitivity level for these parts?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage procedures apply without special environmental controls.
