Digi Connect EM® DC-EM-02T-C Equivalent & Substitute Parts

Part Overview

The DC-EM-02T-C is an embedded module featuring an ARM7TDMI processor running at 55MHz with 8MB RAM and 4MB Flash memory. This module is classified as Obsolete, indicating it has reached end-of-life status and is no longer recommended for new designs. Organizations currently using this component in active systems or requiring replacement units for maintenance and repair operations must identify functionally equivalent alternatives that maintain compatibility with existing hardware and software implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DC-EM-02T-C is determined by the following critical parameters:

Core Technical Specifications: The substitute part must maintain identical processor architecture (ARM7TDMI, NS7520), clock speed (55MHz), RAM capacity (8MB), and Flash memory capacity (4MB). These parameters ensure functional equivalence at the system level.

Physical Interface: The connector type (RJ45) must remain consistent to ensure mechanical compatibility with existing PCB layouts and interconnect systems.

Environmental Compliance: Operating temperature range (-40°C ~ 85°C) and regulatory certifications (RoHS Compliant, REACH Unaffected) must be maintained or exceeded.

Regulatory & Compliance Alignment: Both parts must maintain equivalent ECCN classification and RoHS compliance status to ensure regulatory consistency in deployment environments.

The DC-ME4-01T-S-UPW qualifies as a manufacturer-recommended substitute based on these criteria, despite differences in physical dimensions and product status classification.

Parameter Comparison

Engineering Selection Recommendations

The DC-ME4-01T-S-UPW is designated as the manufacturer-recommended substitute for the obsolete DC-EM-02T-C. Both components share identical core processor architecture, clock frequency, memory configuration, and environmental operating parameters. Regulatory compliance classifications (RoHS, REACH, ECCN) are equivalent between the two parts.

The primary design consideration is the dimensional difference: the substitute part measures 1.450" L x 0.750" W compared to the original 1.940" L x 1.580" W. This reduction in physical footprint requires evaluation of mechanical mounting and interconnect routing within the target application.

Both parts carry product status designations indicating they are no longer in active production. The substitute part status (Not For New Designs) represents a less restrictive classification than the original part (Obsolete), indicating broader availability and continued support from the manufacturer for existing system maintenance.

Frequently Asked Questions (FAQ)

Q: What makes DC-ME4-01T-S-UPW a valid substitute for DC-EM-02T-C?

A: Both parts utilize identical ARM7TDMI, NS7520 processor cores operating at 55MHz with 8MB RAM and 4MB Flash memory. They maintain the same RJ45 connector interface, operating temperature range, and regulatory compliance certifications. These parameters define functional equivalence for embedded module applications.

Q: Are there physical compatibility concerns when substituting these parts?

A: Yes. The substitute part is physically smaller (1.450" L x 0.750" W versus 1.940" L x 1.580" W). PCB layout modifications may be required to accommodate the reduced dimensions. The RJ45 connector remains consistent, but mounting hole patterns and clearance zones must be evaluated for the specific application.

Q: Do both parts meet the same regulatory requirements?

A: Both parts are RoHS Compliant and REACH Unaffected with identical ECCN classification (5A992C). Regulatory compliance is maintained across the substitution.

Q: What is the difference between "Obsolete" and "Not For New Designs" product status?

A: Obsolete indicates the part has reached end-of-life with limited or no availability. Not For New Designs indicates the part is no longer recommended for new applications but may have continued availability for legacy system support. The substitute part's status reflects broader ongoing availability compared to the original part.

Q: Can I use DC-ME4-01T-S-UPW as a direct drop-in replacement?

A: Functional compatibility is established through identical processor, memory, speed, and connector specifications. Physical compatibility requires evaluation of the dimensional differences and PCB layout constraints specific to your application.
