MAX3100EPD Equivalent & Substitute Parts

Part Overview

The MAX3100EPD is a UART SPI Microwire-compatible interface controller manufactured by Analog Devices Inc./Maxim Integrated. This device integrates RS232 and RS485 protocol support with dual interface capability (SPI and UART), housed in a 14-pin DIP package. The MAX3100EPD is classified as obsolete, making equivalent substitute parts necessary for new designs and ongoing system support. Identifying compatible alternatives ensures design continuity and supply chain reliability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MAX3100EPD is determined by strict equivalence across the following critical parameters:

• Base Product Number: Both parts share the MAX3100 base designation, confirming functional equivalence
• Package / Case: Identical 14-DIP (0.300", 7.62mm) physical form factor ensures mechanical compatibility
• Supplier Device Package: Both use 14-PDIP, confirming pinout and footprint compatibility
• Protocol Support: Both support RS232 and RS485 protocols
• Interface Type: Both provide SPI and UART interfaces
• Electrical Specifications: Voltage supply range (2.7V ~ 5.5V), supply current (150µA), and operating temperature range (-40°C ~ 85°C) are identical
• Regulatory Compliance: Both maintain REACH Unaffected status and EAR99 ECCN classification

The MAX3100EPD+ is a direct substitute, differentiated only by active product status and RoHS3 compliance, with packaging in tube format versus the original specification.

Parameter Comparison

Engineering Selection Recommendations

The MAX3100EPD+ is the direct substitute for the MAX3100EPD. Selection between these parts is determined by product lifecycle and regulatory requirements:

MAX3100EPD+ is the preferred choice for new designs and ongoing procurement. This part maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring continued availability and manufacturer support. The MAX3100EPD+ achieves RoHS3 compliance, meeting current environmental and regulatory standards for electronic components. All electrical and functional parameters remain identical to the original MAX3100EPD, ensuring drop-in compatibility at the circuit level.

MAX3100EPD (original) is obsolete and should be replaced in active designs. Existing inventory may be available through authorized distributors, but long-term supply cannot be assured. The RoHS non-compliant status may present regulatory barriers in certain markets and applications.

Both parts share identical pinout, package dimensions, electrical specifications, and functional capabilities, enabling direct substitution without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can MAX3100EPD+ be used as a direct replacement for MAX3100EPD in existing designs?

A: Yes. The MAX3100EPD+ is a direct substitute. Both parts share identical package (14-DIP), pinout (14-PDIP), electrical specifications (2.7V ~ 5.5V supply, 150µA current, -40°C ~ 85°C operating range), and functional capabilities (RS232/RS485 protocols, SPI/UART interfaces). No circuit modifications are required.

Q: What is the primary difference between MAX3100EPD and MAX3100EPD+?

A: The MAX3100EPD+ is the active production variant with RoHS3 compliance and tube packaging. The original MAX3100EPD is obsolete and RoHS non-compliant. All functional and electrical parameters are identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 14-DIP (0.300", 7.62mm) package with 14-PDIP pinout. PCB footprints and mechanical mounting are identical.

Q: Does the RoHS3 compliance of MAX3100EPD+ affect electrical performance?

A: No. RoHS3 compliance relates to material composition and environmental standards, not electrical performance. The MAX3100EPD+ maintains identical voltage supply range, current consumption, and operating temperature specifications.

Q: What is the MSL (Moisture Sensitivity Level) for these parts?

A: Both MAX3100EPD and MAX3100EPD+ have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are these parts subject to export restrictions?

A: Both parts are classified as EAR99 under ECCN, indicating general commercial availability without specific export licensing requirements for most destinations.
