AMK-0221 Equivalent & Substitute Parts Reference

Part Overview

The AMK-0221 is a D-Sub 25 Pin Male to Modular Female Jack adapter connector (6p6c configuration compatible with RJ11, RJ12, RJ14, RJ25 standards) manufactured by CUI Devices. This adapter enables connection between legacy D-Sub 25 pin equipment and modern modular jack interfaces. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this connector type is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AMK-0221 is determined by the following critical parameters:

• Connector Configuration: Input connector must be D-Sub 25 Pin Male; output connector must be Modular Female Jack 6p6c (RJ11, RJ12, RJ14, RJ25 compatible)
• Environmental Compliance: RoHS compliance status and Moisture Sensitivity Level (MSL) rating
• Functional Equivalence: Adapter must perform identical signal conversion between the two connector types

The substitute part AT-23052 maintains identical connector specifications and environmental compliance ratings. The only variance is color (Beige vs. Black) and product status (Active vs. Obsolete), neither of which affects electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: AT-23052 is a direct functional equivalent to AMK-0221. Both parts share identical connector specifications, environmental ratings, and regulatory classifications. The AT-23052 is preferred for new designs and ongoing procurement due to its Active product status, ensuring long-term availability and supply chain stability. The ROHS3 compliance of AT-23052 exceeds the RoHS Compliant rating of the obsolete AMK-0221, providing enhanced regulatory alignment with current standards.

Color Consideration: The color difference (Black vs. Beige) is cosmetic and does not affect electrical or mechanical performance. Selection should be based on system integration requirements and visual identification standards within the application.

Frequently Asked Questions (FAQ)

Q: Can AT-23052 be used as a direct replacement for AMK-0221? A: Yes. Both adapters feature identical D-Sub 25 Pin Male input and Modular 6p6c Female Jack output configurations. Electrical and mechanical compatibility is complete.

Q: Does the color difference affect compatibility? A: No. Color is a cosmetic attribute only and does not impact connector function, signal integrity, or mechanical fit.

Q: Why is AMK-0221 listed as obsolete? A: Obsolete status indicates the part is no longer manufactured by CUI Devices. AT-23052 from Assmann WSW Components provides equivalent functionality with active production status.

Q: Are the RoHS compliance ratings equivalent? A: Both parts meet RoHS requirements. AT-23052 carries ROHS3 certification, which represents the current standard iteration and is fully compatible with systems requiring RoHS Compliant components.

Q: What is the Moisture Sensitivity Level significance? A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special handling or storage conditions. Both parts share this rating.

Q: Are there any regulatory or export restrictions? A: Both parts are classified as EAR99 under ECCN and share identical HTSUS codes (8536.69.8000), indicating equivalent regulatory treatment for export and import purposes.
