Substitute Part Grouping Explanation
Substitution eligibility for the 20-101-0674 is determined by strict equivalence across the following critical parameters:
- Core Processor: Rabbit 3000
- Operating Speed: 22.1MHz
- Internal Flash Memory: 512KB
- External Flash Memory: 1MB
- RAM Capacity: 512kB
- Connector Interface: IDC Header 2x20

Engineering Selection Recommendations
The substitute part 20-101-1305 provides complete functional equivalence to the main part 20-101-0674 across all critical electrical and mechanical parameters. Both parts are discontinued from active production; however, the 20-101-1305 carries RoHS Compliant certification, offering improved environmental compliance for applications subject to RoHS regulations.
Selection between these parts should be based on:
- Availability: Current inventory levels (2100 units for 20-101-0674 versus 981 units for 20-101-1305)
- Regulatory Requirements: If RoHS compliance is mandated, the 20-101-1305 is the appropriate choice
- System Integration: Both parts maintain identical connector interfaces and physical dimensions, ensuring direct mechanical and electrical compatibility
For new system designs, neither part is recommended due to discontinued status. However, for maintenance and replacement of existing systems currently deployed with the 20-101-0674, the 20-101-1305 serves as a direct functional substitute.
Frequently Asked Questions (FAQ)
Q: Can the 20-101-1305 be used as a direct replacement for the 20-101-0674?
A: Yes. Both parts feature identical core processors (Rabbit 3000), operating speeds (22.1MHz), memory configurations (512KB internal flash, 1MB external flash, 512kB RAM), connector types (IDC Header 2x20), physical dimensions, and operating temperature ranges. Direct substitution is supported without circuit modifications.
Q: What is the difference between these two parts?
A: The primary differences are product status and compliance certifications. The 20-101-0674 is marked Obsolete, while the 20-101-1305 is marked Not For New Designs. The 20-101-1305 carries RoHS Compliant certification, whereas RoHS status is not specified for the 20-101-0674. Both maintain REACH Unaffected status.
Q: Are there any packaging differences?
A: Packaging specifications differ slightly. The 20-101-0674 packaging is not specified in available documentation, while the 20-101-1305 is supplied in Bulk packaging. This does not affect electrical or mechanical compatibility.
Q: Which part should I select for a new design?
A: Neither part is recommended for new designs, as both carry discontinued product status. Consult Digi for current-generation RabbitCore embedded modules suitable for new system development.
Q: Are both parts compliant with environmental regulations?
A: Both parts maintain REACH Unaffected status. The 20-101-1305 additionally carries RoHS Compliant certification. If RoHS compliance is a system requirement, the 20-101-1305 is the appropriate selection.
