Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-557089-2 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Receptacle
• Position count: 68 positions
• Row configuration: 2 rows
• Mounting configuration: Free hanging (in-line)
• Termination technology: IDC
• Connector style: Outer shroud contacts
• Contact finish material: Gold
• Series designation: CHAMP .050 I
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 1734098-7 satisfies all mandatory matching parameters, establishing direct functional equivalence with the obsolete 1-557089-2. The primary distinction between these parts relates to product status, packaging format, contact finish thickness specification, and RoHS compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1734098-7 serves as the direct active equivalent for the obsolete 1-557089-2. Both connectors maintain identical electrical and mechanical specifications across all critical parameters including position count, row configuration, mounting style, and termination technology.

Product Status Consideration: The 1-557089-2 is classified as obsolete, while 1734098-7 maintains active product status with confirmed inventory availability (3300 pieces in stock). This status differential establishes 1734098-7 as the appropriate selection for new designs and ongoing production requirements.

Compliance Differentiation: The 1734098-7 achieves ROHS3 compliance, whereas the 1-557089-2 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, 1734098-7 is the mandated selection. Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Contact Finish Specification: The 1-557089-2 specifies gold contact finish at 30.0µin (0.76µm) thickness, while 1734098-7 designates flash gold plating. Both maintain gold contact finish material composition, with thickness variation reflecting manufacturing process differences.

Packaging Format: The 1734098-7 is supplied in tube packaging, providing standardized handling and storage configuration suitable for production environments.

Frequently Asked Questions (FAQ)

Q: Can 1734098-7 directly replace 1-557089-2 in existing applications?

A: Yes. The 1734098-7 maintains identical electrical and mechanical specifications across all critical parameters: 68 positions, 2 rows, free hanging in-line mounting, IDC termination, outer shroud contacts, gold finish, and CHAMP .050 I series designation. Functional compatibility is established.

Q: What is the primary reason for substitution?

A: The 1-557089-2 is classified as obsolete. The 1734098-7 is the active equivalent part with confirmed ongoing availability, making it the appropriate selection for new designs and production continuity.

Q: Does the contact finish thickness difference affect compatibility?

A: Both parts utilize gold contact finish material. The 1-557089-2 specifies 30.0µin (0.76µm) thickness, while 1734098-7 designates flash plating. Both finishes satisfy the functional requirements of the CHAMP .050 I series receptacle connector.
