Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-103149-0 is determined by strict alignment of the following critical parameters:

• Connector Type & Series: Header, Breakaway configuration within AMPMODU Mod II series
• Position Count & Row Configuration: 20 positions arranged in 2 rows
• Pitch Specifications: 0.100" (2.54mm) mating pitch and 0.100" (2.54mm) row spacing
• Mounting Configuration: Through-hole, right-angle mounting
• Contact Specifications: Male pin contacts with matching contact length (mating: 0.230", post: 0.120")
• Electrical Performance: 3A current rating and -65°C ~ 105°C operating temperature range
• Mechanical & Material Standards: UL94 V-0 flammability rating, thermoplastic insulation, square contact shape

The substitute part 6-146308-0 meets all these critical parameters while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The 6-146308-0 serves as the direct active equivalent to the obsolete 1-103149-0. Both parts maintain identical electrical and mechanical specifications across all critical parameters including position count, pitch, mounting configuration, contact geometry, and thermal operating range.

The substitute part offers two significant advantages:

Product Status: The 6-146308-0 is classified as Active, ensuring continued availability and supply chain support, whereas the 1-103149-0 is obsolete.

Regulatory Compliance: The 6-146308-0 is ROHS3 compliant, meeting current environmental and material restriction requirements. The original part is RoHS non-compliant.

Material Enhancement: The 6-146308-0 features glass-filled thermoplastic insulation compared to standard thermoplastic in the original part, providing improved mechanical and thermal stability.

Contact Finish Modification: The post contact finish transitions from tin-lead to tin, eliminating lead content while maintaining solderability and electrical performance.

These characteristics make 6-146308-0 the appropriate selection for new designs and replacement applications requiring current regulatory compliance and supply continuity.

Frequently Asked Questions (FAQ)

Q: Are the 1-103149-0 and 6-146308-0 mechanically interchangeable?

A: Yes. Both connectors share identical mounting configurations (through-hole, right-angle), position counts (20 positions in 2 rows), pitch specifications (0.100" mating and row spacing), and contact geometries (0.230" mating length, 0.120" post length). They are direct mechanical replacements.

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

A: The 1-103149-0 uses tin-lead plating on the post contacts, while the 6-146308-0 uses tin plating. Both finishes provide equivalent solderability and electrical performance. The tin finish in the substitute part eliminates lead content, aligning with RoHS3 compliance requirements.

Q: Does the glass-filled thermoplastic insulation in the 6-146308-0 affect compatibility?

A: No. The glass-filled thermoplastic provides enhanced mechanical and thermal properties while maintaining the same insulation height (0.238"), color (black), and electrical characteristics. It is fully compatible with existing PCB layouts and mating connectors.

Q: Why is the original part obsolete?

A: The 1-103149-0 is classified as obsolete due to its RoHS non-compliant status and the availability of the improved 6-146308-0 variant. TE Connectivity has transitioned production to the active equivalent to meet current regulatory standards.

Q: Can I use the 6-146308-0 in applications originally designed for the 1-103149-0?

A: Yes. The 6-146308-0 is a direct functional and mechanical equivalent with identical electrical ratings (3A current, -65°C ~ 105°C operating range) and contact specifications. It is suitable for all applications previously using the 1-103149-0.

Q: What is the packaging difference between these parts?

A: The 1-103149-0 packaging specification is not provided. The 6-146308-0 is supplied in Tray packaging. Confirm packaging requirements with your procurement specifications.

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

A: Yes. Both connectors are rated for 3A current and operate across the -65°C ~ 105°C temperature range. They meet identical UL94 V-0 flammability standards and have unlimited moisture sensitivity level (MSL 1).
