Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RCM3220 is determined by the following critical parameters: Rabbit 3000 core processor architecture, 2 IDC Headers 2x17 connector compatibility, RoHS compliance, and physical dimensions (1.850" L x 2.730" W). Substitute parts must maintain the same connector interface and processor family to ensure mechanical and functional compatibility.

Two substitute parts are identified:

MFR Recommended Substitute (20-101-0520): Maintains identical processor speed (44.2MHz), RAM (768KB), Flash (512KB), connector type, and physical dimensions. Extended operating temperature range (-40°C ~ 70°C) provides broader environmental capability. Product status is Not For New Designs.

Parametric Equivalent (20-101-0507): Shares the same Rabbit 3000 processor, connector configuration, and physical dimensions. Operates at reduced speed (30MHz) with lower RAM (512KB) and identical Flash (512KB). Product status is Not For New Designs.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: The RabbitCore RCM3200 (20-101-0520) provides the closest functional equivalence to the RCM3220, maintaining identical processor speed, memory configuration, and connector interface. The extended operating temperature range (-40°C ~ 70°C) offers improved environmental tolerance compared to the original specification (0°C ~ 70°C). Both parts maintain RoHS compliance and identical physical dimensions.

For Performance-Constrained Applications: The RabbitCore RCM3000 (20-101-0507) operates at reduced clock speed (30MHz) and lower RAM capacity (512KB versus 768KB). This substitute is suitable only for applications where the performance reduction and memory constraints are acceptable within system requirements. Connector compatibility and physical form factor remain unchanged.

Both substitute parts carry Not For New Designs status, indicating limited future availability. Compliance certifications (RoHS, REACH Unaffected) are maintained across all three modules.

Frequently Asked Questions (FAQ)

Q: Can the RCM3200 (20-101-0520) directly replace the RCM3220 (20-101-0522)?

A: Yes. The RCM3200 maintains identical processor speed (44.2MHz), RAM (768KB), Flash (512KB), connector type (2 IDC Headers 2x17), and physical dimensions. The extended operating temperature range provides additional environmental capability.

Q: What are the limitations of using the RCM3000 (20-101-0507) as a substitute?

A: The RCM3000 operates at 30MHz (versus 44.2MHz) and provides 512KB RAM (versus 768KB). These reductions may impact application performance and memory availability. Connector interface and physical dimensions remain compatible.

Q: Are all substitute parts RoHS compliant?

A: Yes. The RCM3220, RCM3200, and RCM3000 are all RoHS Compliant with REACH Unaffected status.

Q: Do the substitute parts use the same connector configuration?

A: Yes. All three modules utilize 2 IDC Headers 2x17 connectors, ensuring mechanical compatibility with existing carrier boards and interconnect systems.

Q: What is the significance of the "Not For New Designs" status on substitute parts?

A: This designation indicates that while the parts remain available in current inventory, they are not recommended for new product development. Existing systems may continue to use these components for maintenance and support purposes.
