TE Connectivity 746610-6 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 746610-6 is a 26-position ribbon cable DIP header connector designed for through-hole mounting applications. This connector features IDC (Insulation Displacement Contact) termination, accommodating 26-28 AWG stranded or 26-30 AWG solid wire gauges. The connector is classified as Active product status and operates within Moisture Sensitivity Level 1 (unlimited shelf life). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained while offering improved compliance status or enhanced inventory availability.

Substitute Part Grouping Explanation

Substitution eligibility for the 746610-6 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part 1-746610-6 maintains identical specifications in the following areas: connector type (Ribbon Cable, DIP Header), position count (26), cable pitch (0.050"), board-side pitch (0.100"), row configuration (2 rows at 0.100" spacing), mounting method (through hole), termination type (IDC), wire gauge compatibility (26-28 AWG stranded; 26-30 AWG solid), feed-through feature, contact finish thickness (100.0µin), color (black), and moisture sensitivity level (MSL 1).

The primary distinction between the main part and its substitute relates to contact finish composition and RoHS compliance status. These differences do not affect electrical or mechanical interchangeability within the specified parameter set.

Engineering Selection Recommendations

Both the 746610-6 and 1-746610-6 are electrically and mechanically interchangeable based on the provided specifications. Selection between these parts should be based on the following criteria:

RoHS Compliance Requirements: The 1-746610-6 is ROHS3 compliant, while the 746610-6 is RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must utilize the 1-746610-6.

Contact Finish Specification: The 746610-6 features Tin-Lead contact finish, while the 1-746610-6 features Tin contact finish. Both maintain identical contact finish thickness (100.0µin). Applications with specific contact material requirements should reference design documentation.

Inventory Availability: The 1-746610-6 offers significantly higher inventory availability (2440 pcs) compared to the 746610-6 (878 pcs), supporting extended production schedules and supply chain continuity.

Product Status: Both parts maintain Active product status, ensuring continued manufacturer support and availability.

Frequently Asked Questions (FAQ)

Q: Are the 746610-6 and 1-746610-6 electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 26-position configuration, 0.050" cable pitch, 0.100" board-side pitch, IDC termination, and wire gauge compatibility (26-28 AWG stranded; 26-30 AWG solid).

Q: What is the primary difference between these two parts?

A: The primary differences are contact finish composition (Tin-Lead versus Tin) and RoHS compliance status (non-compliant versus ROHS3 compliant). Both maintain identical contact finish thickness and all mechanical parameters.

Q: Can I substitute the 746610-6 with the 1-746610-6 in existing designs?

A: Substitution is mechanically and electrically valid. However, designs requiring RoHS non-compliant components must retain the 746610-6. Designs with RoHS compliance requirements must use the 1-746610-6.

Q: Do these connectors support the same wire gauges?

A: Yes. Both connectors accommodate 26-28 AWG stranded wire and 26-30 AWG solid wire through IDC termination.

Q: What is the pitch configuration for these connectors?

A: Both connectors feature a 0.050" (1.27mm) cable pitch and 0.100" (2.54mm) board-side pitch with 2 rows spaced 0.100" apart.

Q: Are these connectors suitable for through-hole PCB mounting?

A: Yes. Both parts are designed for through-hole mounting applications with feed-through capability.

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

A: Both parts are classified as Moisture Sensitivity Level 1 (MSL 1), indicating unlimited shelf life without special storage requirements.
