Key Parameters

Substitute Part Grouping Explanation

Substitution for the 101-0434 is based on matching the following critical parameters:

• Core Processor: Rabbit 2000
• Speed: 22.1MHz
• Flash Size: 512KB
• RAM Size: 512kB
• Connector Type: 2 IDC Headers 2x20
• Module/Board Type: MPU Core

The substitute part 20-101-0434 maintains identical processor architecture, clock speed, and memory configuration. Both parts use the same connector interface and form factor, ensuring mechanical and electrical compatibility in existing designs.

Parameter Comparison

Engineering Selection Recommendations

The 20-101-0434 serves as a direct substitute for the 101-0434 based on identical core processor, clock frequency, memory configuration, and connector interface. Both parts are classified as end-of-life products (Obsolete and Not For New Designs respectively), indicating limited future availability.

The 20-101-0434 offers improved compliance status with RoHS Compliant certification, whereas the 101-0434 is RoHS non-compliant. However, the 20-101-0434 has a reduced operating temperature range (0°C ~ 70°C versus -40°C ~ 70°C), which may impact suitability for applications requiring extended low-temperature operation.

Selection between these parts should be based on specific application temperature requirements and regulatory compliance needs.

Frequently Asked Questions (FAQ)

Q: Can the 20-101-0434 directly replace the 101-0434 in existing designs?

A: Yes, the 20-101-0434 is electrically and mechanically compatible with the 101-0434. Both modules use identical Rabbit 2000 processors, operate at 22.1MHz, and feature the same 512KB Flash/512KB RAM configuration with 2 IDC Headers 2x20 connectors.

Q: What is the difference in operating temperature range between these parts?

A: The 101-0434 operates from -40°C to 70°C, while the 20-101-0434 operates from 0°C to 70°C. Applications requiring operation below 0°C must use the 101-0434.

Q: Are there compliance differences between the two parts?

A: Yes. The 20-101-0434 is RoHS Compliant, while the 101-0434 is RoHS non-compliant. Both are REACH Unaffected. Applications subject to RoHS regulations should use the 20-101-0434.

Q: Why are both parts classified as end-of-life?

A: The 101-0434 is Obsolete, and the 20-101-0434 is Not For New Designs. Both represent legacy Rabbit 2000 embedded modules. New designs should evaluate current-generation embedded module offerings from Digi.

Q: Are the physical dimensions identical?

A: Yes, both parts measure 2.000" L x 4.600" W (51.00mm x 89.00mm) and use the same connector interface, ensuring identical form factor compatibility.
