• Row spacing: 0.100" (2.54mm)
• Mounting type: Through Hole
• Connector orientation: Vertical

Electrical Compatibility:

• Cable termination method: IDC
• Wire gauge acceptance: 26-30 AWG solid; 26-28 AWG stranded
• Contact finish thickness: 100.0µin (2.54µm)
• Series classification: AMP-Latch

Environmental & Regulatory:

• Moisture sensitivity level: 1 (Unlimited)
• ECCN classification: EAR99
• HTSUS code: 8536.69.4040

The substitute part 746610-6 meets all mechanical, electrical, and environmental criteria for direct substitution. The primary distinction is product status: 746610-6 is active, whereas 111770-6 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity AMP Connectors 746610-6

The 746610-6 is the direct active equivalent to the obsolete 111770-6. Both connectors share identical mechanical dimensions, pitch specifications, mounting configuration, and electrical termination characteristics. The substitute maintains full compatibility with existing PCB layouts and ribbon cable assemblies designed for the 111770-6.

Compliance Considerations:

Both the main part and substitute carry identical RoHS non-compliant and REACH Vendor Undefined designations. Organizations operating under RoHS or REACH regulatory frameworks should evaluate compliance requirements independently of substitution eligibility.

Contact Finish Distinction:

The 111770-6 features a tin contact finish, while the 746610-6 employs a tin-lead contact finish. Both maintain the same 100.0µin (2.54µm) thickness specification. This distinction does not affect mechanical or electrical substitution compatibility but may influence solderability characteristics in specific assembly processes.

Wire Gauge Compatibility:

The 111770-6 accepts 28 AWG stranded or 26-30 AWG solid wire. The 746610-6 accepts 26-28 AWG stranded or 26-30 AWG solid wire. The overlap in solid wire gauge (26-30 AWG) and partial overlap in stranded wire gauge (26-28 AWG) ensures compatibility for standard ribbon cable applications.

Product Status Impact:

The transition from obsolete (111770-6) to active (746610-6) status ensures long-term availability and supply chain continuity. The 746610-6 is currently stocked with 878 pieces in inventory, supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 746610-6 be used as a direct replacement for the 111770-6 in existing assemblies?

A: Yes. The 746610-6 is mechanically and electrically equivalent to the 111770-6. Both connectors feature identical 26-position configuration, 0.050" cable pitch, 0.100" board-side pitch, 2-row layout with 0.100" row spacing, through-hole mounting, and IDC termination. No PCB redesign or cable reconfiguration is required.

Q: What is the difference between the tin and tin-lead contact finishes?

A: The 111770-6 uses tin plating, while the 746610-6 uses tin-lead plating. Both maintain 100.0µin (2.54µm) thickness. The contact finish affects solderability and corrosion resistance characteristics but does not impact mechanical fit or electrical performance in standard applications.

Q: Are there wire gauge compatibility concerns when substituting?

A: The 111770-6 specifies 28 AWG stranded or 26-30 AWG solid wire. The 746610-6 specifies 26-28 AWG stranded or 26-30 AWG solid wire. Both connectors accept 26-30 AWG solid wire without restriction. For stranded wire, the 746610-6 accepts 26-28 AWG, which covers the 28 AWG stranded specification of the 111770-6. Substitution is compatible for standard ribbon cable applications.

Q: Does the packaging difference affect substitution eligibility?

A: The 111770-6 packaging is listed as unspecified, while the 746610-6 is supplied in bulk packaging. Packaging designation does not affect connector form, fit, or function. The bulk packaging of the 746610-6 supports standard procurement workflows.

Q: Are both parts subject to the same regulatory classifications?

A: Yes. Both the 111770-6 and 746610-6 share identical ECCN (EAR99), HTSUS (8536.69.4040), RoHS non-compliant status, and REACH Vendor Undefined designation. Regulatory treatment is equivalent for both parts.

Q: Why is the 111770-6 marked as obsolete?

A: Product obsolescence reflects TE Connectivity's discontinuation of the 111770-6 line. The 746610-6 represents the active continuation of this connector family, ensuring ongoing availability and support for new and replacement applications.

Q: What is the MSL rating significance for these connectors?

A: Both connectors carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints. These connectors do not require special moisture-controlled storage, handling, or pre-soldering baking procedures.
