Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 1-104344-1 is based on strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 13
• Pitch - Mating: 0.100" (2.54mm)
• Contact Type: Male Pin
• Mounting Type: Through Hole
• Termination: Solder
• Current Rating: 3A
• Material Flammability Rating: UL94 V-0
• Contact Finish - Mating: Gold
• Operating Temperature Range: Minimum -65°C, Maximum ≥105°C

The substitute part 77311-103-13LF from Amphenol ICC (FCI) meets all mandatory parameters. This part is classified as active product status, ensuring ongoing availability and supply chain continuity. Both connectors maintain identical pitch spacing, position count, and electrical ratings, enabling direct functional replacement in applications previously designed for the 1-104344-1.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol ICC 77311-103-13LF is the qualified substitute for the obsolete TE Connectivity 1-104344-1 based on the following engineering criteria:

Product Status: The 77311-103-13LF maintains active product status with confirmed inventory availability (1081 pieces in stock), ensuring reliable procurement for both replacement and new design applications. The original 1-104344-1 is classified as obsolete, making the substitute essential for supply chain continuity.

Electrical and Mechanical Compatibility: Both connectors share identical specifications for the critical parameters governing substitution: 13-position configuration, 0.100" (2.54mm) pitch, male pin contact type, through-hole mounting, solder termination, 3A current rating, and UL94 V-0 flammability rating. Contact geometry and gold plating thickness on mating surfaces are equivalent.

Compliance Status: The substitute part 77311-103-13LF is RoHS compliant, whereas the original 1-104344-1 is RoHS non-compliant. Both parts are REACH affected and classified under ECCN EAR99. For applications requiring RoHS compliance, the substitute provides regulatory advantage.

Operating Temperature: The substitute part supports an extended operating temperature range of -65°C to 125°C, compared to the original -65°C to 105°C specification. This provides additional thermal margin for demanding applications.

Contact Material Difference: The substitute uses phosphor bronze contacts versus copper alloy in the original. Both materials are suitable for the specified current and voltage ratings, with phosphor bronze offering enhanced spring characteristics and durability in repeated mating cycles.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 77311-103-13LF directly replace the TE Connectivity 1-104344-1 in existing designs?

A: Yes. Both connectors share identical pitch spacing (0.100" / 2.54mm), position count (13), contact type (male pin), mounting method (through-hole), and electrical ratings (3A). The mating interface and board footprint are compatible. Physical dimensions of the contact mating length differ slightly (0.230" versus 0.225"), but this variation remains within acceptable tolerance for standard PCB receptacle designs.

Q: What is the significance of the contact material difference between the two parts?

A: The original 1-104344-1 uses copper alloy contacts, while the substitute 77311-103-13LF uses phosphor bronze. Both materials are suitable for the specified 3A current rating and 30VAC voltage requirement. Phosphor bronze provides superior spring properties and wear resistance in repeated mating applications, making it a functionally equivalent or superior choice.

Q: Does the RoHS compliance difference affect substitution?

A: The substitute part is RoHS compliant, whereas the original is RoHS non-compliant. For applications subject to RoHS regulations (EU Directive 2011/65/EU and amendments), the substitute provides regulatory compliance. For applications without RoHS requirements, both parts function identically.

Q: Are there packaging differences between these connectors?

A: The original 1-104344-1 packaging specification is not provided in the technical data. The substitute 77311-103-13LF is supplied in bulk packaging. Confirm packaging requirements with your procurement department to ensure compatibility with assembly processes.

Q: What is the impact of the extended operating temperature range of the substitute?

A: The substitute 77311-103-13LF operates from -65°C to 125°C, compared to the original -65°C to 105°C. This 20°C extension at the upper temperature limit provides additional thermal margin for applications operating in elevated ambient conditions or with high-current density scenarios.

Q: Are both connectors suitable for board-to-board applications?

A: Yes. Both the original 1-104344-1 and substitute 77311-103-13LF are specified for board-to-board or cable interconnection. The push-pull fastening mechanism is identical on both parts.

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

A: Both connectors are classified as MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These parts do not require special moisture control during storage, handling, or assembly.
