TE Connectivity 103168-7 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 103168-7 is a shrouded rectangular connector header designed for through-hole mounting applications. This component is a vertical 18-position connector with 2.54mm pitch spacing, configured as a 2-row board-to-board or cable interface. The part operates within the AMPMODU Mod II series and features male pin contacts with gold-plated mating surfaces and tin-lead post finishes.

The 103168-7 carries an obsolete product status, which necessitates identification of equivalent substitute components for ongoing design support and procurement continuity. The substitute part 5-103168-7 provides functional equivalence while offering active product status and improved regulatory compliance.

Substitute Part Grouping Explanation

Substitution between the main part 103168-7 and the equivalent part 5-103168-7 is based on strict electrical and mechanical parameter matching. Both components share identical specifications across all critical functional parameters:

Matching Parameters:

• Connector type, contact type, and pin configuration (18-position, 2-row header)
• Pitch spacing (0.100" mating pitch and row spacing)
• Mounting methodology (through-hole solder termination)
• Physical dimensions (contact lengths, insulation height, overall contact length)
• Contact material and mating surface finish (gold-plated mating surfaces)
• Electrical performance (3A current rating, -65°C to 105°C operating range)
• Safety certification (UL94 V-0 flammability rating)

Distinguishing Characteristics: The primary differences between these parts are product status (obsolete versus active), packaging format (unspecified versus tray), post contact finish composition (tin-lead versus tin), and regulatory compliance status (RoHS non-compliant versus RoHS compliant; REACH affected versus REACH unaffected).

Parameter Comparison

Engineering Selection Recommendations

The 5-103168-7 serves as the direct functional equivalent to the obsolete 103168-7 within the AMPMODU Mod II connector series. Both parts maintain identical electrical and mechanical specifications, ensuring direct interchangeability in applications requiring 18-position, 2-row through-hole headers with 2.54mm pitch spacing and 3A current capacity.

Selection of the 5-103168-7 is supported by its active product status, which ensures ongoing availability and manufacturing support. The substitute part incorporates RoHS compliance and REACH unaffected status, providing regulatory advantages for applications subject to environmental and hazardous substance restrictions. The transition from tin-lead to tin post contact finish in the substitute part aligns with contemporary lead-free manufacturing standards while maintaining equivalent electrical performance and contact reliability.

For applications where legacy tin-lead post finishes are specifically required, the obsolete 103168-7 remains functionally equivalent; however, procurement of this part is subject to availability constraints due to its discontinued status.

Frequently Asked Questions (FAQ)

Q: Are the 103168-7 and 5-103168-7 directly interchangeable?

A: Yes. Both parts share identical connector type, pin configuration, pitch spacing, mounting methodology, and electrical ratings. The parts are mechanically and electrically compatible for direct substitution in board-to-board and cable interface applications.

Q: What is the significance of the product status difference between these parts?

A: The 103168-7 is classified as obsolete, indicating discontinued manufacturing and limited procurement availability. The 5-103168-7 maintains active product status, ensuring continued manufacturing support, availability, and compliance with current regulatory standards.

Q: How does the post contact finish difference affect performance?

A: The 103168-7 features tin-lead post finish, while the 5-103168-7 uses tin post finish. Both finishes provide equivalent solder joint reliability and electrical performance. The tin finish in the substitute part reflects alignment with lead-free manufacturing practices.

Q: Are there packaging differences between these parts?

A: The 103168-7 packaging is unspecified in available documentation. The 5-103168-7 is supplied in tray packaging. Packaging format does not affect functional performance or interchangeability.

Q: What are the RoHS and REACH compliance implications?

A: The 103168-7 is RoHS non-compliant and REACH affected. The 5-103168-7 is RoHS compliant and REACH unaffected. For applications subject to RoHS or REACH regulatory requirements, the 5-103168-7 is the appropriate selection.

Q: Can the 103168-7 be used in new designs?

A: The obsolete status of the 103168-7 makes it unsuitable for new design implementations. The 5-103168-7 is the recommended selection for all new applications requiring this connector type and configuration.

Q: Are the electrical and thermal specifications identical?

A: Yes. Both parts operate across the identical temperature range (-65°C to 105°C), carry the same 3A current rating, and maintain equivalent contact material composition and surface finishes on mating surfaces.

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

A: Both parts carry MSL 1 (Unlimited) classification, indicating no moisture sensitivity constraints for storage, handling, or assembly processes.
