TE Connectivity AMP Connectors 554381-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 554381-2 is a 64 Position Receptacle Connector with free hanging (in-line) mounting and IDC termination. This D-Sub, D-shaped connector belongs to the CHAMP .085 series and features outer shroud contacts with latch lock functionality. The part is currently active in production with 652 pieces available in new original stock condition.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across connector position count, row configuration, termination method, mounting style, and contact specifications. Alternative part numbers may be required due to packaging availability, inventory levels, or compliance requirement differences between manufacturing batches.

Substitute Part Grouping Explanation

Substitution eligibility for the 554381-2 is determined by strict equivalence across the following critical parameters:

• Connector Position Count: 64 positions required
• Row Configuration: 2 rows required
• Termination Technology: IDC (Insulation Displacement Contact) required
• Mounting Configuration: Free hanging (in-line) required
• Contact Material and Finish: Gold plating at 30.0µin (0.76µm) thickness required
• Connector Style: Outer shroud contacts required
• Series Classification: CHAMP .085 series required
• Mechanical Interface: Housing/Shell with 4-40 flange feature required
• Locking Mechanism: Latch lock feature required

The substitute part 5554381-2 maintains full equivalence across all electrical and mechanical parameters. The primary difference between the main part and its substitute is the packaging format and associated compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the 554381-2 and 5554381-2 are active production parts manufactured by TE Connectivity AMP Connectors with identical electrical and mechanical specifications. Selection between these parts is determined by application requirements and compliance mandates.

554381-2 is suitable for applications where RoHS compliance is not a requirement or where bulk packaging is preferred. This part maintains full functional equivalence with the substitute.

5554381-2 is the appropriate selection for applications requiring ROHS3 compliance certification. This part is supplied in tray packaging and has higher inventory availability (1429 pieces versus 652 pieces). The substitute maintains complete electrical and mechanical compatibility with the main part number.

Both parts share identical contact finish specifications, termination technology, connector geometry, and mechanical interface characteristics. The choice between them depends solely on packaging format preference and regulatory compliance requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Are the 554381-2 and 5554381-2 electrically interchangeable?

A: Yes. Both parts are 64-position receptacle connectors with IDC termination, identical contact finish specifications (gold plating at 30.0µin thickness), and equivalent electrical performance characteristics. They are fully interchangeable from an electrical standpoint.

Q: What is the primary difference between these two part numbers?

A: The primary differences are packaging format and RoHS compliance status. The 554381-2 is supplied in bulk packaging with RoHS status listed as not applicable. The 5554381-2 is supplied in tray packaging and carries ROHS3 compliance certification.

Q: Can I use 5554381-2 as a direct replacement for 554381-2?

A: Yes. The 5554381-2 maintains complete mechanical and electrical equivalence with the 554381-2. All connector parameters including position count, row configuration, termination method, mounting style, contact finish, and mechanical interface are identical.

Q: Does the tray packaging of 5554381-2 affect connector performance?

A: No. Packaging format does not affect connector electrical or mechanical performance. Tray packaging is a logistics and handling consideration only. The connector specifications and functionality remain unchanged.

Q: Which part should I specify for new designs?

A: Selection depends on regulatory requirements. If ROHS3 compliance is required, specify 5554381-2. If RoHS compliance is not a design requirement, either part number is acceptable. Both parts are active in production.

Q: Are there any compatibility issues between these connectors and existing mating components?

A: No compatibility issues exist. Both connectors share identical mechanical interfaces, flange features (Housing/Shell 4-40), and connector geometry. They mate with identical plug connectors and cable assemblies.

Q: What is the moisture sensitivity level for both parts?

A: Both the 554381-2 and 5554381-2 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
