TE Connectivity AMP Connectors 1-104345-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-104345-1 is a rectangular connector header designed for through-hole mounting applications. This connector features 13 vertical positions with 0.100" (2.54mm) pitch spacing and is part of the AMPMODU Mod II series. The part is classified as obsolete, making identification of equivalent substitute components necessary for ongoing design support, maintenance, and production continuity. Substitute parts must maintain functional compatibility across critical electrical and mechanical parameters including pitch, position count, current rating, voltage rating, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1-104345-1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Pitch - Mating: 0.100" (2.54mm)
• Number of Positions: 13
• Number of Rows: 1
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Current Rating: 3A minimum
• Voltage Rating: 30VAC minimum
• Operating Temperature Range: Must encompass -65°C to 105°C
• Material Flammability Rating: UL94 V-0

Acceptable Variation Parameters:

• Connector Type: Header variants (breakaway or standard)
• Contact Finish: Gold or equivalent conductive finish on mating surface
• Insulation Material: Thermoplastic
• Shrouding: Unshrouded
• Contact Shape: Square

The substitute part 77311-103-13LF from Amphenol ICC (FCI) meets all mandatory matching parameters and is classified as an active product, providing superior long-term availability compared to the obsolete main part.

Engineering Selection Recommendations

Primary Substitute: Amphenol ICC 77311-103-13LF

The 77311-103-13LF is the qualified substitute for the obsolete TE Connectivity 1-104345-1. Selection of this substitute is supported by the following engineering factors:

Product Status Advantage: The substitute part is classified as active product status, ensuring continued availability and supply chain reliability. The main part is obsolete, creating long-term sourcing risk.

Compliance Enhancement: The substitute part is RoHS compliant, whereas the main part is RoHS non-compliant. This provides regulatory advantage for applications subject to RoHS directives.

Electrical and Mechanical Compatibility: All critical parameters align between the main part and substitute, including pitch (0.100"), position count (13), contact type (male pin), current rating (3A), and flammability rating (UL94 V-0).

Operating Temperature: The substitute part operates across -65°C to 125°C, which exceeds the main part's -65°C to 105°C range, providing additional thermal margin.

Certification Alignment: Both parts carry UL94 V-0 flammability rating and are REACH affected, maintaining consistent regulatory framework.

Frequently Asked Questions (FAQ)

Q: What makes the 77311-103-13LF a valid substitute for the 1-104345-1?

A: The substitute part matches all critical parameters: 13-position, 0.100" pitch, male pin header, through-hole mounting, 3A current rating, UL94 V-0 flammability, and operating temperature range that encompasses the original part's specifications. Both are unshrouded, single-row rectangular connectors with square contacts and thermoplastic insulation.

Q: Does the substitute part fit the same PCB footprint?

A: Yes. Both parts share identical pitch (0.100"), position count (13), and single-row configuration. Through-hole mounting dimensions are compatible for standard PCB layouts designed for the original part.

Q: What is the difference in contact length between these parts?

A: The main part has an overall contact length of 0.440" (11.18mm), while the substitute has 0.525" (13.34mm). This difference reflects design variations between manufacturers but does not affect functional compatibility in standard through-hole applications.

Q: Is the substitute part RoHS compliant?

A: Yes. The 77311-103-13LF is RoHS compliant, whereas the original 1-104345-1 is RoHS non-compliant. This provides regulatory advantage for new designs and applications subject to RoHS requirements.

Q: Can I use the substitute part in existing designs without modification?

A: Yes. The substitute part maintains electrical and mechanical compatibility with the original part across all critical parameters. No PCB redesign or circuit modification is required.

Q: What is the operating temperature range of the substitute part?

A: The substitute part operates from -65°C to 125°C, which exceeds the original part's -65°C to 105°C range. This provides additional thermal margin for demanding applications.

Q: Are both parts available in the same packaging?

A: The original part packaging is not specified. The substitute part is available in bulk packaging. Consult with the supplier for specific packaging options and quantities.

Q: What contact finish is used on the substitute part?

A: The substitute part features gold or gold GXT™ finish on the mating surface, matching the gold finish of the original part. The post finish is tin, compared to tin-lead on the original part.
