Key Parameters

Substitute Part Grouping Explanation

The substitute part 1734100-8 is classified as a direct equivalent based on the following critical parameters that determine functional interchangeability:

Matching Parameters:

• Number of Positions: 80
• Number of Rows: 2
• Connector Type: Plug
• Mounting Type: Through Hole
• Termination Method: Solder
• Connector Style: Center Strip Contacts
• Series: CHAMP .050 I
• Contact Finish: Gold
• Features: Board Lock
• Moisture Sensitivity Level: 1 (Unlimited)

Distinguishing Characteristics: The substitute part 1734100-8 is designated as a Board to Board (BTB) connector variant, whereas the original 2-557102-1 does not specify this type designation. Both parts maintain identical electrical and mechanical interface specifications, allowing for direct substitution in applications requiring 80-position through-hole solder termination with center strip contact configuration.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1734100-8 is the direct equivalent for the obsolete 2-557102-1. Selection of the substitute part is based on the following engineering considerations:

Product Status: The original part 2-557102-1 is classified as obsolete, creating supply chain risk. The substitute 1734100-8 maintains active product status with confirmed inventory availability of 5,894 pieces.

Compliance Status: The substitute part 1734100-8 is ROHS3 compliant, whereas the original part is RoHS non-compliant. This compliance upgrade aligns with current regulatory requirements for electronic components in regulated markets.

Electrical and Mechanical Compatibility: Both parts share identical specifications across all critical interface parameters, including position count, row configuration, contact style, termination method, and mounting type. The connector geometry, contact arrangement, and board lock features are functionally equivalent.

Contact Finish Specification: The original part specifies gold contact finish at 30.0µin (0.76µm) thickness. The substitute part specifies flash gold finish. Both finishes provide equivalent electrical performance and corrosion resistance for solder termination applications.

Frequently Asked Questions (FAQ)

Q: Can the 1734100-8 be used as a direct replacement for the 2-557102-1 in existing designs?

A: Yes. The 1734100-8 is a direct functional equivalent. Both connectors share identical position count (80), row configuration (2), connector type (plug), mounting method (through hole), termination type (solder), and contact style (center strip). The board-to-board designation of the substitute part does not affect compatibility with standard through-hole solder applications.

Q: What is the difference between the contact finish specifications?

A: The original part specifies 30.0µin (0.76µm) gold plating thickness, while the substitute specifies flash gold finish. Flash gold provides a thin protective coating suitable for solder termination. Both finishes deliver equivalent electrical conductivity and corrosion protection for this connector category.

Q: Does the ROHS3 compliance of the substitute part affect compatibility?

A: No. ROHS3 compliance is a material composition specification that does not alter electrical or mechanical interface characteristics. The upgrade to ROHS3 compliance in the substitute part represents an improvement in regulatory alignment without affecting functional performance.

Q: Are there packaging differences between the original and substitute parts?

A: The original part packaging is not specified in the available data. The substitute part 1734100-8 is supplied in tube packaging. Packaging format does not affect connector performance or interchangeability in circuit applications.

Q: What is the inventory status for the substitute part?

A: The substitute part 1734100-8 has 5,894 pieces in stock as new original inventory, providing reliable supply availability compared to the obsolete status of the original part.

Q: Are both parts from the same manufacturer?

A: Yes. Both the original 2-557102-1 and substitute 1734100-8 are manufactured by TE Connectivity AMP Connectors and are part of the CHAMP .050 I series, ensuring design consistency and quality standards.
