TE Connectivity AMP Connectors 557102-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 557102-5 is a 40 Position Plug Connector featuring through-hole solder termination and center strip contacts. This connector is part of the CHAMP .050 I series and includes board lock features with gold-plated contacts. The 557102-5 is classified as obsolete, making identification of suitable substitute components necessary for ongoing design support, maintenance, and production continuity. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 557102-5 is based on strict alignment of the following critical parameters:

Electrical Compatibility Parameters:

• Number of Positions: 40
• Number of Rows: 2
• Connector Type: Plug
• Termination Method: Solder
• Contact Finish: Gold

Mechanical Compatibility Parameters:

• Connector Style: Center Strip Contacts
• Mounting Type: Through Hole
• Series: CHAMP .050 I
• Features: Board Lock

Environmental & Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8536.69.4040

The substitute part 1734100-4 maintains all critical electrical and mechanical parameters required for functional equivalence. The primary distinction is the connector application type (Board to Board versus standard plug configuration) and compliance status upgrade (ROHS3 Compliant versus RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The 557102-5 is classified as obsolete, while the substitute part 1734100-4 maintains active product status with 2460 units in current inventory compared to 715 units of the obsolete part. Active status ensures continued availability and manufacturing support.

Compliance Status: The 1734100-4 is ROHS3 Compliant, whereas the 557102-5 is RoHS non-compliant. For applications subject to RoHS regulations or requiring compliance with current environmental standards, the 1734100-4 provides regulatory alignment.

Functional Equivalence: Both parts share identical electrical and mechanical specifications across all critical parameters: 40-position configuration, 2-row arrangement, center strip contact style, through-hole solder termination, CHAMP .050 I series designation, gold contact finish, and board lock features. The connector type designation difference (Board to Board for 1734100-4 versus standard plug for 557102-5) does not preclude functional substitution in applications where the 557102-5 was originally specified.

Contact Finish Specification: The 557102-5 specifies 30.0µin (0.76µm) contact finish thickness, while the 1734100-4 specifies flash thickness. Both gold finishes meet the electrical and environmental protection requirements of the CHAMP .050 I series.

Frequently Asked Questions (FAQ)

Q: Can the 1734100-4 directly replace the 557102-5 in existing designs?

A: The 1734100-4 maintains all critical electrical and mechanical parameters required for functional equivalence: 40 positions, 2 rows, center strip contacts, through-hole solder termination, CHAMP .050 I series compatibility, gold plating, and board lock features. Direct substitution is supported from a connector specification standpoint.

Q: What is the difference between the connector type designations (Plug versus Board to Board Plug)?

A: Both parts are classified as plug connectors. The 1734100-4 designation as "Board to Board" indicates its intended application for board-to-board interconnection, while the 557102-5 is designated as a standard plug. This distinction reflects application context rather than fundamental connector architecture differences. Both maintain identical contact arrangements and termination methods.

Q: How does the contact finish thickness difference affect compatibility?

A: The 557102-5 specifies 30.0µin (0.76µm) gold plating, while the 1734100-4 specifies flash gold plating. Both finishes provide electrical conductivity and environmental protection appropriate to the CHAMP .050 I series specification. The flash finish on the 1734100-4 is standard for current production and meets all functional requirements.

Q: Why is RoHS compliance status different between these parts?

A: The 557102-5 predates current RoHS regulations and is classified as non-compliant. The 1734100-4 is manufactured to ROHS3 standards, reflecting current environmental and regulatory requirements. For applications requiring RoHS compliance, the 1734100-4 is the appropriate selection.

Q: Are there packaging differences between these parts?

A: The 557102-5 packaging is not specified in available documentation. The 1734100-4 is supplied in bag packaging. Packaging format does not affect connector functionality or electrical performance.

Q: What is the inventory status for each part?

A: The 557102-5 has 715 units in stock as new original inventory. The 1734100-4 has 2460 units in stock as new original inventory. The higher inventory level for the active part supports longer-term availability assurance.
