Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 104346-5 is based on strict equivalence of the following critical parameters:

Electrical Compatibility Parameters:

• Contact Type: Male Pin
• Number of Positions: 7
• Pitch - Mating: 0.100" (2.54mm)
• Current Rating: 3A
• Operating Temperature Range: -65°C ~ 105°C

Mechanical Compatibility Parameters:

• Connector Type: Header, Breakaway
• Mounting Type: Through Hole
• Contact Shape: Square
• Insulation Height: 0.090" (2.29mm)
• Overall Contact Length: 0.440" (11.18mm)

Compliance Parameters:

• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 5-146278-7 maintains all critical electrical and mechanical parameters while transitioning from obsolete to active product status. Variations in contact finish material (Tin-Lead to Tin) and insulation material (Thermoplastic to Liquid Crystal Polymer) do not affect functional compatibility within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 5-146278-7 is the direct functional equivalent of the obsolete 104346-5. Both components are members of the AMPMODU Mod II series and maintain identical electrical and mechanical specifications across all critical parameters including pitch, position count, current rating, and operating temperature range.

Product Status Consideration: The 104346-5 is classified as obsolete. The 5-146278-7 maintains active product status, ensuring continued availability and manufacturing support for new designs and production continuity.

Compliance Advantage: The substitute part 5-146278-7 is RoHS Compliant, whereas the main part 104346-5 is RoHS non-compliant. This transition aligns with current regulatory requirements for electronic components in regulated markets.

Material Improvements: The substitute incorporates Liquid Crystal Polymer (LCP) insulation material in place of thermoplastic, providing enhanced thermal and mechanical stability. Copper Alloy contact material replaces phosphor bronze while maintaining electrical performance. Tin contact finish replaces tin-lead, supporting lead-free manufacturing initiatives.

Functional Interchangeability: Both parts are through-hole mounted, 7-position headers with 0.100" (2.54mm) pitch, identical contact geometries, and equivalent current and voltage ratings. Direct substitution is supported for all applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the 5-146278-7 be used as a direct replacement for the 104346-5 in existing designs?

A: Yes. The 5-146278-7 maintains identical electrical and mechanical specifications including pitch, position count, contact geometry, current rating, and operating temperature range. Direct substitution is supported without design modification.

Q: What is the difference between the contact finishes (Tin-Lead vs. Tin)?

A: The main part 104346-5 uses Tin-Lead contact finish, while the substitute 5-146278-7 uses Tin finish. Both finishes provide equivalent electrical conductivity and corrosion resistance within the specified operating parameters. The Tin finish in the substitute aligns with lead-free manufacturing standards.

Q: Does the change from Thermoplastic to Liquid Crystal Polymer (LCP) insulation affect compatibility?

A: No. Both insulation materials meet UL94 V-0 flammability requirements and maintain the same insulation height and electrical properties. LCP provides enhanced thermal stability and mechanical strength, representing a material improvement.

Q: Why is the 104346-5 listed as obsolete?

A: The 104346-5 has been discontinued by TE Connectivity. The 5-146278-7 is the active equivalent that replaces it in the product line, ensuring continued availability and support for new applications.

Q: Are there any packaging differences between these parts?

A: The main part 104346-5 packaging is not specified in the available data. The substitute 5-146278-7 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: What is the RoHS compliance status, and does it matter for my application?

A: The 104346-5 is RoHS non-compliant, while the 5-146278-7 is RoHS Compliant. If your application or market requires RoHS compliance, the substitute part is the appropriate selection.

Q: Are both parts rated for the same current and voltage?

A: Both parts are rated for 3A current. The main part 104346-5 is rated for 30VAC. The substitute 5-146278-7 does not specify a voltage rating in the available data. Confirm voltage requirements with application specifications.

Q: Can these connectors be used in high-temperature applications?

A: Yes. Both parts operate across the temperature range of -65°C to 105°C, supporting applications requiring extended thermal performance within this range.
