TE Connectivity 1-103327-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1-103327-1 is an 11-position AMPMODU Mod II rectangular connector header designed for through-hole mounting with 0.100" (2.54mm) pitch. This connector features male pins, unshrouded design, and push-pull fastening, rated for 3A continuous current across an operating temperature range of -65°C to 105°C.

The 1-103327-1 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support legacy system maintenance where this connector type remains in use.

Substitute Part Grouping Explanation

Substitution of the 1-103327-1 is determined by strict equivalence across the following critical parameters:

Connector geometry: 11-position, single-row, 0.100" pitch header with male pins
Mechanical interface: Through-hole solder termination with push-pull fastening
Electrical performance: 3A current rating and -65°C to 105°C operating temperature range
Physical dimensions: Contact length, insulation height, and overall form factor
Reliability standards: UL94 V-0 flammability rating

The substitute part 6-146278-1 maintains full equivalence across all critical parameters. Differences in contact finish material (Tin-Lead vs. Tin) and insulation material (Thermoplastic vs. Liquid Crystal Polymer) do not affect functional compatibility within the specified electrical and thermal operating envelope.

Engineering Selection Recommendations

The 6-146278-1 is the direct substitute for the obsolete 1-103327-1. Both parts belong to the AMPMODU Mod II series and maintain identical mechanical and electrical specifications across all critical parameters.

The primary distinction is product status: the 1-103327-1 is obsolete, while the 6-146278-1 is active and currently manufactured. For new designs or ongoing production requiring this connector type, the 6-146278-1 is the appropriate selection to ensure supply chain continuity and long-term availability.

The contact finish difference (Tin-Lead vs. Tin) reflects manufacturing evolution and does not impact functional compatibility. Both finishes meet the same electrical conductivity and corrosion resistance requirements within the specified operating conditions. The insulation material upgrade from Thermoplastic to Liquid Crystal Polymer (LCP) in the substitute part provides enhanced thermal and mechanical stability without altering the connector's electrical or mechanical interface.

Frequently Asked Questions (FAQ)

Q: Can the 6-146278-1 be used as a direct replacement for the 1-103327-1 in existing designs?

A: Yes. The 6-146278-1 maintains full mechanical and electrical compatibility with the 1-103327-1. All critical parameters—pitch, position count, contact geometry, current rating, and operating temperature range—are identical. The connector will function identically in existing PCB layouts and mating applications.

Q: What is the significance of the contact finish change from Tin-Lead to Tin?

A: Both finishes provide equivalent electrical performance and corrosion resistance within the specified operating environment. The change reflects industry-wide transition toward lead-free manufacturing practices. No functional difference exists for applications operating within the -65°C to 105°C temperature range at 3A current levels.

Q: Does the insulation material change from Thermoplastic to Liquid Crystal Polymer affect compatibility?

A: No. The insulation material change does not affect the connector's mechanical interface, mating dimensions, or electrical performance. Liquid Crystal Polymer offers improved thermal stability and dimensional consistency, representing a material enhancement rather than a functional change.

Q: Why is the 1-103327-1 marked as obsolete?

A: Obsolete status indicates the part is no longer manufactured by TE Connectivity. The 6-146278-1 represents the current production equivalent within the AMPMODU Mod II series, ensuring ongoing availability and supply chain support.

Q: Are there any compliance or certification differences between these parts?

A: Both parts carry identical compliance designations: UL94 V-0 flammability rating, EAR99 export classification, and HTSUS code 8536.69.4040. No compliance or certification differences exist.
