Key Parameters

Substitute Part Grouping Explanation

Substitution of the 104426-4 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header, Breakaway)
• Contact type (Male Pin)
• Number of positions (6)
• Number of rows (1)
• Pitch - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Contact dimensions (mating length, post length, overall length)
• Insulation height
• Contact shape (Square)

Electrical Compatibility:

• Contact finish - mating (Gold)
• Contact material (Copper Alloy)
• Operating temperature range (-65°C ~ 105°C)
• Current rating (3A)
• Material flammability rating (UL94 V-0)
• Fastening type (Push-Pull)

Series Compatibility:

• AMPMODU Mod II series designation

The substitute part 5-146277-6 maintains full equivalence across all mechanical and electrical parameters. Variations in insulation material (Thermoplastic vs. Liquid Crystal Polymer), contact finish post composition (Tin-Lead vs. Tin), and product status (Obsolete vs. Active) do not affect functional interchangeability within the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 5-146277-6 is the manufacturer-recommended equivalent for the obsolete 104426-4. Both connectors maintain identical mechanical and electrical specifications across all critical parameters, ensuring direct functional interchangeability in existing circuit designs.

Product Status Consideration: The 104426-4 is classified as obsolete, while 5-146277-6 is an active product with significantly higher inventory availability (15,240 pieces versus 1,080 pieces). Selection of the active substitute part ensures long-term supply chain continuity and supports future production requirements.

Regulatory Compliance: The substitute part 5-146277-6 achieves RoHS compliance and REACH unaffected status, compared to the non-compliant status of the original part. This improvement aligns with current regulatory requirements for electronic components in most markets.

Material Specification: The substitute part utilizes Liquid Crystal Polymer (LCP) insulation material in place of Thermoplastic, providing enhanced thermal and mechanical properties. The contact finish post composition changes from Tin-Lead to Tin, reflecting current manufacturing standards and regulatory trends away from lead-containing materials.

Packaging: The substitute part is supplied in bulk packaging, suitable for production environments requiring component quantities. The original part packaging specification was not provided.

Selection of 5-146277-6 is supported by identical electrical performance, mechanical compatibility, improved product status, and enhanced regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Are the 104426-4 and 5-146277-6 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including connector type, contact configuration, pitch, mounting type, contact dimensions, and insulation height. Direct substitution is supported without circuit board redesign or mechanical modification.

Q: What is the difference in insulation material between these parts?

A: The 104426-4 uses Thermoplastic insulation, while the 5-146277-6 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range (-65°C to 105°C). LCP provides enhanced thermal stability and mechanical rigidity.

Q: Does the change from Tin-Lead to Tin contact finish affect performance?

A: No. Both contact finish specifications maintain identical thickness (100.0µin / 2.54µm) on the post. The change from Tin-Lead to Tin reflects current manufacturing standards and regulatory compliance with lead reduction initiatives. Electrical and mechanical performance remain equivalent.

Q: Why is the 104426-4 listed as obsolete?

A: The 104426-4 has been discontinued by the manufacturer. The 5-146277-6 is the active replacement part within the AMPMODU Mod II series, offering identical functionality with improved availability and regulatory compliance.

Q: Can I use 5-146277-6 in existing designs specified for 104426-4?

A: Yes. The substitute part maintains full electrical and mechanical compatibility. No circuit design changes, PCB modifications, or mating connector updates are required. Direct component replacement is supported.

Q: What is the inventory status of these parts?

A: The 104426-4 has 1,080 pieces in stock. The 5-146277-6 has 15,240 pieces in stock, providing significantly greater availability for current and future production requirements.

Q: Are both parts RoHS compliant?

A: The 104426-4 is RoHS non-compliant. The 5-146277-6 is RoHS compliant. If RoHS compliance is required for your application, the substitute part 5-146277-6 is the appropriate selection.

Q: What is the current rating for both connectors?

A: Both the 104426-4 and 5-146277-6 are rated for 3A per contact, supporting identical electrical load specifications.

Q: Are there any packaging differences between these parts?

A: The 104426-4 packaging specification was not provided. The 5-146277-6 is supplied in bulk packaging suitable for production environments.
