TE Connectivity AMP Connectors 553811-3 D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 553811-3 is a 24-position D-Sub receptacle connector designed for panel mount, through-hole, right-angle solder termination applications. This connector features an outer shroud contact design with gold-plated contacts and shielding for signal integrity in industrial and commercial electronic assemblies.

The 553811-3 carries an obsolete product status, making identification of functionally equivalent alternatives necessary for ongoing production support, maintenance, and design continuity. Substitute parts must maintain identical electrical and mechanical specifications while offering active product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 553811-3 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Mandatory Matching Parameters:

• Connector type: Receptacle
• Position count: 24 positions
• Row configuration: 2 rows
• Mounting configuration: Panel mount, through-hole, right-angle orientation
• Termination method: Solder
• Connector style: Outer shroud contacts
• Shielding: Present
• Contact finish material: Gold
• Contact finish thickness: 30.0µin (0.76µm)
• Series designation: CHAMP .085
• Moisture sensitivity level: 1 (Unlimited)

The 5553811-3 meets all mandatory equivalence criteria and qualifies as a direct substitute. Differences in packaging format (tray versus bulk), product status (active versus obsolete), compliance certifications (RoHS3 compliant versus non-compliant), and flange feature design (housing/shell versus board side) do not affect functional interchangeability in the connector interface itself.

Parameter Comparison

Engineering Selection Recommendations

The 5553811-3 is the direct functional equivalent to the obsolete 553811-3 and is suitable for substitution in new designs and production applications.

Product Status Consideration: The 553811-3 is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The 5553811-3 maintains active product status, ensuring supply chain continuity and manufacturing support.

Compliance Advantage: The 5553811-3 achieves RoHS3 compliance and REACH unaffected status, compared to the non-compliant and vendor-undefined status of the 553811-3. This compliance improvement aligns with current regulatory requirements for electronic component procurement in regulated industries.

Packaging Difference: The 5553811-3 is supplied in tray packaging, whereas the 553811-3 is supplied in bulk format. Packaging format does not affect connector performance or interchangeability; selection depends on inventory management and assembly process requirements.

Flange Feature Difference: The 5553811-3 incorporates a housing/shell flange feature, while the 553811-3 uses a board-side flange feature. Both configurations maintain the 4-40 mounting specification and panel-mount through-hole installation method. Flange design differences do not compromise electrical or mechanical interface compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 5553811-3 be used as a direct replacement for the 553811-3 in existing assemblies?

A: Yes. The 5553811-3 maintains identical electrical and mechanical specifications across all critical connector parameters, including position count, row configuration, mounting type, termination method, contact finish, and shielding. The connector interface is fully compatible.

Q: What is the significance of the flange feature difference between board side and housing/shell?

A: Both flange configurations support panel-mount, through-hole installation with 4-40 mounting specifications. The flange feature difference relates to the internal structural design of the connector housing and does not affect the connector's electrical performance or mating interface.

Q: Does the packaging difference (tray versus bulk) affect connector performance?

A: No. Packaging format is a logistics and inventory management consideration only. Tray packaging and bulk packaging contain identical connectors with no functional differences.

Q: Why is RoHS3 compliance important for the 5553811-3 substitute?

A: RoHS3 compliance ensures the connector meets current regulatory requirements for restricted hazardous substances in electronic components. This certification is required for many commercial and industrial applications and simplifies procurement compliance documentation.

Q: Are there any installation or soldering differences between the 553811-3 and 5553811-3?

A: No. Both connectors use identical solder termination methods and panel-mount through-hole installation procedures. Assembly processes and soldering parameters remain unchanged.

Q: What is the moisture sensitivity level, and why is it relevant?

A: Both connectors carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture-controlled storage or handling procedures and can be stored and handled under standard environmental conditions.
