AMK-0224 D-Sub to RJ45 Adapter Equivalent & Substitute Parts

Part Overview

The AMK-0224 is a D-Sub 25 Pin Female to Modular Female Jack (8p8c/RJ45) adapter connector manufactured by CUI Devices. This adapter enables conversion between legacy D-Sub serial interfaces and modern modular RJ45 connectors. The product is currently obsolete, making equivalent substitute parts necessary for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AMK-0224 are qualified based on the following critical parameters:

• Connector Interface Compatibility: Convert From must be D-Sub, 25 Pin Female; Convert To must be Modular, Female Jack, 8p8c (RJ45)
• Color Match: Black finish for direct replacement without visual distinction
• Environmental Rating: MSL 1 (Unlimited) for unrestricted storage and handling
• Regulatory Compliance: RoHS compliance status for regulatory alignment
• Export Classification: ECCN EAR99 for consistent trade compliance

Two substitute parts meet these criteria: RJADK25S7080811 (black) and RJADK25S7080831 (gray). The black variant (RJADK25S7080811) provides direct functional and aesthetic equivalence to the AMK-0224.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: RJADK25S7080811

This NorComp Inc. part provides complete functional and aesthetic equivalence to the obsolete AMK-0224. Both parts share identical connector specifications (D-Sub 25 Pin Female to RJ45 8p8c), black color finish, and environmental ratings. The RJADK25S7080811 carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

Alternative Substitute: RJADK25S7080831

This gray variant maintains all functional parameters and compliance certifications of the primary substitute. Selection of this part is appropriate when color distinction is not a system requirement or when gray finish is preferred for visual identification purposes.

Frequently Asked Questions (FAQ)

Q: Can RJADK25S7080811 directly replace AMK-0224 in existing installations?

A: Yes. Both parts convert D-Sub 25 Pin Female connectors to RJ45 8p8c Female Jack connectors with identical electrical and mechanical specifications. The black color finish ensures visual consistency with the original component.

Q: What is the difference between RJADK25S7080811 and RJADK25S7080831?

A: The parts are functionally identical. The primary difference is color: RJADK25S7080811 is black, while RJADK25S7080831 is gray. Both meet all electrical, mechanical, and compliance requirements for substitution.

Q: Are there any compliance differences between the original and substitute parts?

A: The original AMK-0224 is RoHS Compliant. The substitute parts (RJADK25S7080811 and RJADK25S7080831) are ROHS3 Compliant, representing an updated compliance standard. Both meet current regulatory requirements.

Q: Does packaging affect compatibility?

A: No. The AMK-0224 and substitute parts are functionally identical regardless of packaging format. Packaging differences (bag vs. other formats) do not affect electrical or mechanical performance.

Q: Why is the AMK-0224 listed as obsolete?

A: Product obsolescence indicates the manufacturer has discontinued production. The substitute parts from NorComp Inc. are Active products with current manufacturing support, making them suitable for ongoing component sourcing.
