TE Connectivity 1-746610-2 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-746610-2 is a 64-position ribbon cable DIP header connector with IDC termination for 26-28 AWG stranded and 26-30 AWG solid wire gauges. This connector is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design and procurement requirements. The connector features through-hole mounting, tin-lead contact finish, and feed-through capability in a 2-row configuration with 0.100" (2.54mm) board-side pitch and 0.050" (1.27mm) cable pitch.

Substitute Part Grouping Explanation

Substitution of the 1-746610-2 is determined by strict equivalence across the following critical parameters: connector type (ribbon cable DIP header), number of positions (64), number of rows (2), cable pitch (0.050"), board-side pitch (0.100"), row spacing (0.100"), mounting type (through hole), cable termination method (IDC), wire gauge compatibility (26-28 AWG stranded and 26-30 AWG solid), and feed-through feature presence.

Substitute parts are grouped into two categories:

Direct Equivalent: Parts that maintain identical electrical and mechanical specifications with the main part, differing only in product status or compliance certifications.

Functional Equivalent: Parts that maintain all critical dimensional and electrical parameters but may differ in contact finish composition, color, or packaging format while preserving full mechanical and electrical compatibility.

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 2-746610-5

The 2-746610-5 is the direct equivalent substitute for the obsolete 1-746610-2. Both parts are manufactured by TE Connectivity AMP Connectors within the same AMP-Latch series and maintain identical electrical and mechanical specifications. The 2-746610-5 is currently in active production status with ROHS3 compliance and REACH unaffected status, providing superior long-term availability and regulatory alignment compared to the obsolete main part. The contact finish differs only in composition (tin versus tin-lead), which does not affect mechanical or electrical compatibility. This part is the preferred choice for direct replacement in new designs and legacy system updates.

Secondary Recommendation: Amphenol ICC 69830-064LF

The 69830-064LF serves as a functional equivalent from an alternative manufacturer (Amphenol ICC, FCI Quickie™ series). This part maintains all critical dimensional and electrical parameters identical to the main part and offers active product status with RoHS compliance and REACH affected status. The contact finish thickness is increased to 150.0µin (3.81µm) compared to the main part's 100.0µin, providing enhanced durability in high-cycle applications. The connector color is blue rather than black. This part is suitable for applications where multi-source qualification is required or where Amphenol ICC components are preferred within the supply chain.

Tertiary Option: Amphenol ICC 69830-064

The 69830-064 is functionally equivalent but maintains RoHS non-compliant status and tin-lead contact finish identical to the main part. This part is suitable only for legacy systems or applications where RoHS compliance is not a requirement. The 69830-064LF is preferred over this part due to superior compliance status.

Frequently Asked Questions (FAQ)

Q: Can the 2-746610-5 be used as a direct replacement for the 1-746610-2 in existing designs?

A: Yes. The 2-746610-5 maintains identical connector type, position count, pitch specifications, mounting type, cable termination method, wire gauge compatibility, and feed-through features. The only differences are product status (active versus obsolete), RoHS compliance (ROHS3 versus non-compliant), and contact finish composition (tin versus tin-lead). These differences do not affect mechanical or electrical compatibility.

Q: What is the difference between the TE Connectivity and Amphenol ICC options?

A: Both manufacturers provide 64-position ribbon cable DIP header connectors with identical pitch and mounting specifications. The primary differences are manufacturer source, connector color (black for TE Connectivity, blue for Amphenol ICC), and compliance certifications. The Amphenol ICC 69830-064LF offers increased contact finish thickness (150.0µin versus 100.0µin), which may provide enhanced contact durability in high-cycle insertion applications.

Q: Are there any wire gauge limitations when substituting parts?

A: No. All substitute parts support 26-28 AWG stranded and 26-30 AWG solid wire gauges, matching the main part's specifications. The Amphenol ICC parts specify "26-28 AWG stranded or solid," which encompasses the main part's wire gauge range.

Q: Does the contact finish difference between tin and tin-lead affect compatibility?

A: No. Both tin and tin-lead finishes are compatible with standard soldering and IDC termination processes. The contact finish composition does not affect mechanical fit, electrical conductivity, or connector performance within the specified parameters.

Q: What is the significance of the contact finish thickness difference in the 69830-064LF?

A: The 69830-064LF features 150.0µin (3.81µm) contact finish thickness compared to 100.0µin (2.54µm) in the main part and other substitutes. This increased thickness provides additional material for wear resistance in applications involving repeated insertion and withdrawal cycles, though it does not affect initial electrical or mechanical compatibility.

Q: Are all substitute parts available in the same packaging format?

A: No. The 2-746610-5 is supplied in bulk packaging, while the Amphenol ICC parts (69830-064 and 69830-064LF) are supplied in tube packaging. Packaging format does not affect connector performance but may influence procurement and inventory management procedures.

Q: Which substitute part should be selected for new designs requiring RoHS compliance?

A: Both the TE Connectivity 2-746610-5 (ROHS3 compliant) and the Amphenol ICC 69830-064LF (RoHS compliant) meet RoHS requirements. The 2-746610-5 is recommended as the primary choice due to manufacturer continuity with the original part source.
