Key Parameters

Substitute Part Grouping Explanation

Substitution of the 3-557102-7 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 160
• Number of Rows: 2
• Connector Type: Plug
• Connector Style: Center Strip Contacts
• Mounting Type: Through Hole
• Termination: Solder
• Series: CHAMP .050 I
• Contact Finish: Gold
• Features: Board Lock

The substitute part 1-1734100-6 satisfies all mandatory matching parameters. The primary distinction between the main part and the substitute is the connector application type: the main part is a standard vertical plug connector, while the substitute is a board-to-board (BTB) vertical plug connector. Both maintain identical electrical and mechanical interface specifications within the CHAMP .050 I series architecture.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1-1734100-6 is an active product with ROHS3 compliance, addressing the obsolescence status of the main part 3-557102-7. Both parts maintain identical electrical and mechanical specifications within the CHAMP .050 I series, including 160-position configuration, center strip contact architecture, through-hole solder termination, and board lock features.

The primary distinction is the connector application designation: the substitute is specified as a board-to-board (BTB) connector, whereas the main part is a standard plug connector. Both parts share identical contact geometry, pitch, and interface specifications. The substitute's active product status and ROHS3 compliance provide advantages for new designs and manufacturing environments with regulatory requirements.

Selection between these parts depends on application requirements: the main part is suitable for legacy systems already in production, while the substitute is appropriate for new designs, production continuity, and compliance-driven applications.

Frequently Asked Questions (FAQ)

Q: Can the 1-1734100-6 substitute directly replace the 3-557102-7 in existing designs?

A: Both parts share identical electrical and mechanical interface specifications within the CHAMP .050 I series. The 160-position configuration, center strip contact architecture, through-hole solder termination, and board lock features are identical. The primary difference is the connector application type designation (board-to-board versus standard plug). Physical compatibility depends on the specific mounting and mating interface requirements of the application.

Q: What is the significance of the board-to-board (BTB) designation on the substitute part?

A: The BTB designation indicates the connector is designed for board-to-board applications. However, both the main part and substitute maintain the same contact geometry, pitch, and interface specifications within the CHAMP .050 I series. The designation reflects intended application context rather than fundamental electrical or mechanical differences.

Q: Are there compliance differences between the main part and substitute?

A: Yes. The main part 3-557102-7 is RoHS non-compliant and obsolete. The substitute part 1-1734100-6 is ROHS3 compliant and active. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The substitute's compliance status is advantageous for manufacturing environments with regulatory requirements.

Q: What is the contact finish specification for both parts?

A: Both parts feature gold contact finish. The main part specifies 30.0µin (0.76µm) contact finish thickness. The substitute specifies flash contact finish. Both maintain gold plating for electrical conductivity and corrosion resistance.

Q: Are both parts available in the same packaging?

A: The main part packaging is not specified in the provided data. The substitute part 1-1734100-6 is packaged in boxes. Inventory availability differs: the main part has 969 pieces in stock, while the substitute has 1466 pieces in stock.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or use.
