Key Parameters

Substitute Part Grouping Explanation

Substitution for the RabbitCore RCM2200 (20-101-0454) is based on the following critical parameters that must remain consistent:

• Core Processor: Rabbit 2000
• Processor Speed: 22.1MHz
• Connector Type: 2 IDC Headers 2x13
• Physical Dimensions: 1.600" L x 2.300" W (41.00mm x 58.00mm)
• Operating Temperature Range: 0°C ~ 70°C
• RoHS Compliance: Required

The identified substitute part (20-101-0494) maintains all core electrical and mechanical compatibility parameters. The primary difference is increased memory capacity (Flash: 512KB, RAM: 512KB versus the original 256KB Flash and 128KB RAM), which represents an enhancement rather than a functional deviation. Both parts share identical processor architecture, clock speed, physical form factor, and connector configuration.

Parameter Comparison

Engineering Selection Recommendations

The RabbitCore RCM2200 (20-101-0454) is classified as Obsolete. The substitute part 20-101-0494 is classified as Not For New Designs, indicating both parts have reached end-of-life status within Digi's product portfolio.

For applications currently using 20-101-0454, the 20-101-0494 provides direct electrical and mechanical compatibility with enhanced memory resources. Both parts maintain RoHS compliance and identical operating temperature specifications. The increased Flash and RAM capacity in the substitute part does not introduce incompatibility; rather, it provides additional headroom for application code and data storage.

Selection between these parts should be based on inventory availability and specific application memory requirements. Both parts share identical processor architecture, clock frequency, and physical form factor, ensuring pin-level and mechanical compatibility in existing designs.

Frequently Asked Questions (FAQ)

Q: Can 20-101-0494 directly replace 20-101-0454 in existing designs?

A: Yes. Both parts use the Rabbit 2000 processor at 22.1MHz, feature identical 2 IDC Headers 2x13 connectors, and share the same physical dimensions (1.600" L x 2.300" W). The increased memory in 20-101-0494 (512KB Flash and RAM versus 256KB Flash and 128KB RAM) does not create incompatibility.

Q: What is the primary difference between these two parts?

A: The main difference is memory capacity. The 20-101-0494 provides 512KB Flash and 512KB RAM compared to the 20-101-0454's 256KB Flash and 128KB RAM. All other electrical and mechanical parameters remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both 20-101-0454 and 20-101-0494 are RoHS Compliant and REACH Unaffected.

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

A: Both parts operate within the range of 0°C to 70°C.

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

A: 20-101-0454 is Obsolete, and 20-101-0494 is Not For New Designs. This indicates Digi has discontinued active production and support for the RabbitCore RCM2200 series. Existing inventory may be available through authorized distributors.

Q: Are the connector types identical?

A: Yes. Both parts use 2 IDC Headers 2x13 connectors, ensuring mechanical and electrical compatibility.
