Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RabbitCore RCM2000 20-101-0383 is determined by the following critical parameters:

Core Compatibility Requirements:

• Same processor family (Rabbit 2000)
• Identical connector type (2 IDC Headers 2x20)
• Matching physical dimensions (1.900" L x 2.300" W)
• Compatible operating temperature range (-40°C to 85°C)

Performance Considerations:

• Operating speed may vary (18.432MHz baseline)
• Flash and RAM memory configurations may differ
• Substitutes must maintain or exceed memory capacity for functional equivalence

Compliance & Certification:

• RoHS Compliant status required
• Moisture Sensitivity Level 1 maintained
• REACH Unaffected status preserved

The identified substitute part 20-101-0404 meets all core compatibility requirements while offering enhanced performance specifications in speed and memory capacity within the same RabbitCore RCM2000 series.

Parameter Comparison

Engineering Selection Recommendations

The RabbitCore RCM2000 20-101-0404 serves as a direct substitute for 20-101-0383 based on identical core processor architecture, connector configuration, physical form factor, and thermal operating range. Both modules maintain RoHS compliance and MSL 1 rating, ensuring compatibility with existing assembly and storage protocols.

The 20-101-0404 provides enhanced performance through increased operating speed (25.8MHz versus 18.432MHz) and expanded RAM capacity (512KB versus 128KB), while maintaining identical Flash memory (256KB) and physical dimensions. These improvements support legacy system maintenance without requiring mechanical or electrical redesign of host interfaces.

Both parts carry end-of-life status classifications (Obsolete and Not For New Designs respectively), indicating limited future availability. Selection between these parts should prioritize inventory availability and application-specific performance requirements within the constraint of identical mechanical and electrical interfaces.

Frequently Asked Questions (FAQ)

Q: Can the 20-101-0404 directly replace the 20-101-0383 in existing designs?

A: Yes. Both modules share identical connector types (2 IDC Headers 2x20), physical dimensions (1.900" L x 2.300" W), operating temperature range (-40°C to 85°C), and core processor family (Rabbit 2000). Direct mechanical and electrical substitution is supported without host board modification.

Q: What are the key differences between these two modules?

A: The 20-101-0404 operates at 25.8MHz compared to 18.432MHz on the 20-101-0383, and provides 512KB RAM versus 128KB. Flash memory remains 256KB on both modules. These differences represent performance enhancements within the same product family.

Q: Are there compliance or certification differences between the parts?

A: Both modules maintain RoHS Compliant status, MSL 1 (Unlimited) rating, and REACH Unaffected classification. Compliance profiles are equivalent for assembly, storage, and deployment environments.

Q: What is the significance of the product status classifications?

A: The 20-101-0383 is classified as Obsolete, indicating end-of-life with no further production. The 20-101-0404 is classified as Not For New Designs, indicating limited availability and unsuitability for new product development. Both statuses reflect the legacy nature of the RabbitCore RCM2000 series.

Q: Are there any packaging differences?

A: The 20-101-0383 packaging is unspecified in available documentation. The 20-101-0404 is packaged in Box format. Packaging differences do not affect functional compatibility or electrical performance.
