AMK-0223 Equivalent & Substitute Parts

Part Overview

The AMK-0223 is a D-Sub 25 Pin Male to Modular Female Jack (8p8c/RJ45) adapter connector manufactured by CUI Devices. This adapter enables conversion between legacy D-Sub serial interfaces and modern RJ45 modular connections. The part is currently obsolete, making equivalent substitutes necessary for ongoing system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMK-0223 is determined by the following critical parameters:

• Connector Interface Conversion: D-Sub 25 Pin Male input and Modular Female Jack 8p8c (RJ45) output
• Physical Color: Black housing
• Environmental Compliance: RoHS compliance status
• Moisture Sensitivity: MSL 1 rating (unlimited moisture exposure tolerance)
• Export Classification: EAR99 designation

The substitute part RJADK25P7080811 meets all these criteria, establishing direct functional equivalence for applications requiring D-Sub to RJ45 adapter functionality.

Parameter Comparison

Engineering Selection Recommendations

The RJADK25P7080811 from NorComp Inc. is the direct equivalent substitute for the obsolete AMK-0223. Selection is based on:

• Identical Connector Configuration: Both parts provide D-Sub 25 Pin Male to RJ45 Female Jack conversion
• Matching Environmental Ratings: Both maintain MSL 1 and EAR99 compliance
• Enhanced RoHS Compliance: The substitute meets ROHS3 requirements, exceeding the original RoHS Compliant specification
• Active Product Status: The substitute is currently in active production with confirmed inventory availability (1240 units), ensuring long-term sourcing reliability

No functional or mechanical differences exist between these parts for standard D-Sub to RJ45 adapter applications.

Frequently Asked Questions (FAQ)

Q: Can RJADK25P7080811 directly replace AMK-0223 in existing installations?

A: Yes. Both parts provide identical D-Sub 25 Pin Male to Modular Female Jack 8p8c (RJ45) conversion with matching environmental ratings and compliance certifications.

Q: What is the significance of the MSL 1 rating for both parts?

A: MSL 1 indicates unlimited moisture exposure tolerance, meaning these adapters require no special moisture control during storage, handling, or installation.

Q: Are there packaging differences between these parts?

A: The AMK-0223 uses standard packaging, while RJADK25P7080811 is supplied in bag packaging. This does not affect functional performance or compatibility.

Q: Why is the original AMK-0223 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by CUI Devices. The RJADK25P7080811 remains in active production and serves the same functional purpose.

Q: Do both parts meet current RoHS requirements?

A: Yes. The AMK-0223 is RoHS Compliant, and the RJADK25P7080811 meets the more stringent ROHS3 standard, ensuring compliance with current environmental regulations.
