Frequently Asked Questions (FAQ)

Q: What determines compatibility between the TE Connectivity 1-281523-6 and HARTING SEK series substitutes?

A: Compatibility is established through identical specifications for connector type (header), contact type (male pin), number of positions (16), pitch (2.54mm), row spacing (2.54mm), mounting type (through hole, right angle), shrouding (4-wall), termination (solder), mating contact length (6.10mm), insulation height (8.51mm), insulation material (PBT glass-filled), mating contact finish (gold), and flammability rating (UL94 V-0).

Q: Can I substitute any HARTING SEK part for the original TE Connectivity connector?

A: All listed HARTING SEK parts maintain functional compatibility at the mating interface. Selection depends on post-contact length requirements and fastening hook configuration for your specific application. Verify post-contact length and hook type match your board design requirements.

Q: What is the difference between long and short fastening hooks?

A: Fastening hook length affects the mechanical engagement depth with the mating connector. Long hooks provide extended engagement, while short hooks provide reduced engagement depth. Selection depends on your cable connector design and retention requirements.

Q: How do post-contact lengths of 0.114" and 0.177" affect board design?

A: Post-contact length determines the depth of solder joint penetration into the printed circuit board. The original part specifies 0.122" (3.10mm). HARTING substitutes offer 0.114" (2.90mm) for shallow board penetration or 0.177" (4.50mm) for deeper penetration. Verify your PCB design accommodates the selected post length.

Q: Are HARTING SEK parts available in different packaging formats?

A: Yes. HARTING 09185166903 and 09185166913 are supplied in tray packaging. All other listed HARTING SEK parts are supplied in bulk packaging. Packaging selection affects inventory management and component handling procedures.

Q: What compliance improvements do HARTING substitutes provide?

A: HARTING SEK series parts are ROHS3 compliant and REACH unaffected, addressing current regulatory requirements. All parts maintain UL94 V-0 flammability rating and MSL 1 (unlimited) moisture sensitivity level. Operating temperature range of -55°C to 125°C is specified for all HARTING parts.

Q: Can I mix different HARTING SEK variants in the same assembly?

A: All listed HARTING SEK variants maintain identical mating interface specifications. However, verify that post-contact length and fastening hook configuration are consistent across your assembly to ensure uniform board design and cable connector compatibility.

Q: What is the contact shape difference between the original and substitutes?

A: The original TE Connectivity part features circular contact shape. All HARTING SEK substitutes feature square contact shape. Both geometries are compatible with standard 2.54mm pitch mating connectors and do not affect functional performance.
