TE Connectivity AMP Connectors 103185-5 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103185-5 is a rectangular connector header from the AMPMODU Mod II series, designed for through-hole board-to-board or cable applications with 5 positions at 0.100" (2.54mm) pitch. This connector features male pins with gold-plated mating contacts and tin-lead plated posts, rated for 3A current and operating temperatures from -65°C to 105°C.

The 103185-5 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or maintenance requirements for legacy systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 103185-5 is determined by strict alignment with the following critical parameters:

• Connector type: Header, Breakaway configuration
• Contact type: Male Pin
• Number of positions: 5
• Mating pitch: 0.100" (2.54mm)
• Mounting method: Through Hole
• Termination method: Solder
• Current rating: 3A minimum
• Operating temperature range: -65°C ~ 105°C minimum
• Contact finish (mating surface): Gold plating
• Flammability rating: UL94 V-0

The substitute part 5-146280-5 meets all these criteria. Both connectors share identical mechanical and electrical specifications for mating interface, pin configuration, and environmental performance. The primary differences are product status (active vs. obsolete) and insulation material composition (Liquid Crystal Polymer vs. Thermoplastic), which do not affect functional compatibility in the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

The 5-146280-5 is the direct substitute for the obsolete 103185-5. Both connectors maintain identical electrical and mechanical specifications across all critical mating parameters, ensuring functional interchangeability in applications requiring 5-position, 0.100" pitch through-hole headers with 3A current capacity and -65°C to 105°C operating range.

The 5-146280-5 offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. Additionally, the substitute part achieves RoHS compliance and REACH unaffected status, providing regulatory advantages for new designs and production environments subject to these compliance frameworks. The insulation material change from Thermoplastic to Liquid Crystal Polymer (LCP) provides improved thermal and mechanical stability without affecting connector performance within the specified operating envelope.

The post contact finish change from Tin-Lead to Tin reflects current manufacturing standards and environmental compliance trends, with no impact on solder joint reliability or electrical performance.

Frequently Asked Questions (FAQ)

Q: Are the 103185-5 and 5-146280-5 mechanically interchangeable?

A: Yes. Both connectors share identical pitch (0.100"), position count (5), contact geometry, and mounting footprint. They are mechanically interchangeable in through-hole PCB applications.

Q: What is the difference in insulation material, and does it affect performance?

A: The 103185-5 uses Thermoplastic insulation, while the 5-146280-5 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements and operate across the identical temperature range (-65°C ~ 105°C). LCP provides enhanced thermal stability and dimensional consistency, but this does not alter electrical or mechanical compatibility.

Q: Why does the post contact finish differ between the two parts?

A: The 103185-5 features Tin-Lead plating on posts, while the 5-146280-5 uses Tin plating. This reflects the transition to lead-free manufacturing standards. Both finishes provide equivalent solder joint reliability and electrical performance at the 3A current rating.

Q: Is the 5-146280-5 suitable for applications originally designed for the 103185-5?

A: Yes. The substitute part meets all electrical and mechanical requirements of the original design. The active product status and improved compliance profile (RoHS compliant, REACH unaffected) make it suitable for both legacy system maintenance and new production.

Q: What is the packaging difference between these parts?

A: The 103185-5 packaging specification is not provided. The 5-146280-5 is supplied in Bulk packaging. Confirm packaging requirements with your procurement or supply chain team if specific packaging formats are required.

Q: Are there any soldering or assembly considerations when switching to the 5-146280-5?

A: No. Both connectors use identical solder termination methods and post dimensions (0.120" length, 100.0µin plating thickness). Standard through-hole soldering processes apply to both parts without modification.
