Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DC-ME-01T-PC is determined by the following critical parameters:

• Processor Architecture: ARM7TDMI, NS7520 core at 55MHz
• Memory Configuration: 8MB RAM minimum
• Physical Form Factor: 1.450" L x 0.750" W dimensions
• Connector Interface: RJ45 network connectivity
• Operating Temperature Range: -40°C to 85°C capability
• Compliance Standards: RoHS compliance and MSL rating

The DC-ME4-01T-C qualifies as a direct substitute based on matching processor, speed, RAM capacity, physical dimensions, connector type, temperature range, and compliance certifications. The primary difference is increased Flash memory (4MB versus 2MB), which represents an enhancement rather than a limitation for compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DC-ME4-01T-C is the designated manufacturer substitute for the obsolete DC-ME-01T-PC. Selection of the substitute part is justified by:

• Product Status Alignment: The substitute maintains active product status, ensuring continued availability and manufacturer support
• Functional Equivalence: Identical processor architecture, clock speed, RAM capacity, physical form factor, and connector interface ensure drop-in compatibility
• Compliance Continuity: Both parts maintain RoHS compliance and MSL rating 1, preserving regulatory and environmental requirements
• Enhanced Specification: The increased Flash memory (4MB) in the substitute provides additional storage capacity without introducing incompatibility

Frequently Asked Questions (FAQ)

Q: Can DC-ME4-01T-C directly replace DC-ME-01T-PC in existing designs?

A: Yes. Both modules share identical processor architecture, speed, RAM capacity, physical dimensions, and connector type. The increased Flash memory in the substitute represents a specification enhancement.

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

A: Flash memory capacity differs: DC-ME-01T-PC provides 2MB while DC-ME4-01T-C provides 4MB. All other electrical and mechanical parameters are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain RoHS compliance and MSL rating 1 (Unlimited), ensuring equivalent regulatory and environmental performance.

Q: Does the physical form factor remain the same?

A: Yes. Both modules maintain identical dimensions of 1.450" L x 0.750" W (36.70mm x 19.10mm) and use RJ45 connectors, ensuring mechanical compatibility.

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

A: Both the DC-ME-01T-PC and DC-ME4-01T-C operate across -40°C to 85°C, supporting industrial temperature applications.
