TE Connectivity AMP Connectors 552740-1 D-Sub Receptacle Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 552740-1 is a 24-position D-Sub receptacle connector configured for panel mount, through-hole, right-angle solder termination. This connector belongs to the CHAMP .085 series and features outer shroud contacts with gold-plated contact finish. The 552740-1 is classified as obsolete, making identification of active equivalent parts essential for ongoing procurement and system maintenance. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or board modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 552740-1 is determined by strict equivalence across all electrical and mechanical parameters. The primary substitute part 5552740-1 qualifies as a direct equivalent based on the following criteria:

Matching Parameters:

• Connector type: Receptacle
• Position count: 24 positions in 2-row configuration
• Mounting configuration: Panel mount, through-hole, right-angle orientation
• Termination method: Solder
• Connector style: Outer shroud contacts
• Series designation: CHAMP .085
• Contact finish specification: Gold at 30.0µin (0.76µm) thickness
• Flange feature: Housing/Shell (4-40)

The 5552740-1 maintains complete functional and mechanical compatibility with the obsolete 552740-1, differing only in product status (active versus obsolete) and packaging format (tray versus unspecified).

Parameter Comparison

Engineering Selection Recommendations

The 5552740-1 serves as the direct active equivalent for the obsolete 552740-1. Selection of the 5552740-1 is supported by the following factors:

Product Status: The 5552740-1 maintains active product status with TE Connectivity AMP Connectors, ensuring ongoing availability and supply chain continuity. The 552740-1 is classified as obsolete, creating procurement risk for new applications and production runs.

Regulatory Compliance: The 5552740-1 is ROHS3 compliant, meeting current environmental and hazardous substance restrictions. The 552740-1 is RoHS non-compliant, which may present regulatory barriers in applications subject to RoHS directives.

Electrical and Mechanical Equivalence: Both parts maintain identical specifications across all functional parameters, including connector type, position count, mounting configuration, termination method, contact finish, and flange features. No circuit redesign or mechanical modification is required for substitution.

Inventory Availability: The 5552740-1 is available in higher inventory quantities (985 pieces) compared to the 552740-1 (704 pieces), supporting both immediate procurement and long-term supply planning.

Frequently Asked Questions (FAQ)

Q: Can the 5552740-1 be used as a direct replacement for the 552740-1 in existing designs?

A: Yes. The 5552740-1 is electrically and mechanically equivalent to the 552740-1 across all specified parameters. No circuit modifications, board redesign, or connector interface changes are required. The parts are interchangeable at the component level.

Q: What is the primary difference between the 552740-1 and 5552740-1?

A: The primary differences are product status and regulatory compliance. The 552740-1 is obsolete and RoHS non-compliant, while the 5552740-1 is active and ROHS3 compliant. Both parts are functionally identical in electrical and mechanical specifications.

Q: Does the packaging format difference affect compatibility?

A: No. The 552740-1 is supplied in unspecified packaging, while the 5552740-1 is supplied in tray packaging. Packaging format does not affect connector performance, electrical characteristics, or mechanical fit. The difference is logistical only.

Q: Are there any restrictions on using the 5552740-1 in applications previously designed for the 552740-1?

A: No restrictions exist based on the provided specifications. Both parts share identical connector type, position count, mounting configuration, termination method, contact finish, and flange features. The 5552740-1 is suitable for all applications previously using the 552740-1.

Q: What is the significance of the ROHS3 compliance on the 5552740-1?

A: ROHS3 compliance indicates that the 5552740-1 meets current European Union Restriction of Hazardous Substances directives. This compliance status is required for many commercial and industrial applications, particularly in markets subject to EU regulations. The obsolete 552740-1 does not carry this certification.

Q: Are the moisture sensitivity levels identical between both parts?

A: Yes. Both the 552740-1 and 5552740-1 are rated at MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage, handling, or assembly processes.

Q: Can the 5552740-1 be used in new product designs?

A: Yes. The 5552740-1 is classified as active and is the recommended choice for new designs. Its active status ensures long-term availability, supply chain support, and regulatory compliance alignment with current standards.
