RabbitCore RCM4000 Embedded Module 20-101-1094 Equivalent & Substitute Parts

Part Overview

The RabbitCore RCM4000 (Digi part number 20-101-1094) is an embedded module featuring a Rabbit 4000 processor operating at 58.98MHz with 512KB internal flash memory and 32MB external flash memory. This module is classified as obsolete and is no longer recommended for new designs. Due to its discontinued status, identifying compatible substitute parts is essential for ongoing system maintenance, legacy system support, and component procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RabbitCore RCM4000 is determined by strict alignment of the following critical parameters:

• Core processor type and speed (Rabbit 4000 at 58.98MHz)
• Internal flash memory capacity (512KB)
• RAM capacity (512kB)
• Connector type and pinout (IDC Header 2x25, 2x5)
• Physical dimensions (1.840" L x 2.420" W / 47.00mm x 61.00mm)
• Operating temperature range (0°C ~ 70°C)
• Compliance certifications (RoHS, REACH)

The RabbitCore RCM4010 (part number 20-101-1112) meets these substitution criteria as a functionally equivalent alternative. While the RCM4010 has reduced external flash memory (not specified in substitute data versus 32MB in the original), it maintains identical core processor specifications, memory architecture, connector configuration, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

The RabbitCore RCM4010 (20-101-1112) is the designated substitute for the obsolete RCM4000. Both modules are classified as legacy products: the RCM4000 is obsolete, while the RCM4010 is marked "Not For New Designs." Both maintain full RoHS compliance and REACH unaffected status, ensuring regulatory alignment for existing applications.

Selection between these parts should be based on inventory availability and application requirements. The RCM4010 is currently available in higher stock quantities (1218 units versus 712 units for the RCM4000), making it the preferred choice for procurement of replacement modules in legacy system support scenarios.

Frequently Asked Questions (FAQ)

Q: Can the RCM4010 directly replace the RCM4000 in existing designs?

A: Yes. Both modules share identical core processor specifications (Rabbit 4000 at 58.98MHz), memory configuration (512KB internal flash, 512kB RAM), connector type (IDC Header 2x25, 2x5), physical dimensions, and operating temperature range. Pin-level compatibility is maintained.

Q: What is the difference in external flash memory between these modules?

A: The RCM4000 specifies 32MB external flash memory. The RCM4010 specification does not include external flash memory data in the provided parameters. Applications requiring specific external memory capacity should be evaluated against actual system requirements.

Q: Are both modules RoHS compliant?

A: Yes. Both the RCM4000 and RCM4010 are RoHS compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the RCM4000 marked as obsolete?

A: The RCM4000 has reached end-of-life status and is no longer manufactured. The RCM4010, while marked "Not For New Designs," remains available for legacy system support and replacement applications.

Q: What packaging options are available?

A: The RCM4000 is supplied in standard packaging. The RCM4010 is available in bulk packaging, which may affect procurement quantities and handling requirements.
