Engineering Selection Recommendations

The TE Connectivity 2-281523-0 is classified as obsolete. All listed HARTING SEK series alternatives are active products with current manufacturing status, ensuring long-term availability and supply chain continuity.

Compliance Advantages of HARTING Substitutes:

All HARTING alternatives provide ROHS3 compliance and REACH Unaffected status, compared to the main part's undefined compliance posture. This positions substitute parts favorably for applications subject to environmental regulations.

Selection Criteria by Contact Post Length:

0.177" (4.50mm) Post Length: HARTING 09185205901, 09185205911, 09185206901, 09185206911, 09185207901. These variants accommodate deeper PCB penetration and are suitable for applications requiring extended solder joint engagement.
0.114" (2.90mm) Post Length: HARTING 09185205913, 09185206903, 09185206903001, 09185206913, 09185207903. These variants provide reduced post length for applications with shallow PCB thickness or space constraints.

Fastening Type Variants:

Latch Lock/Eject Hooks (Long): 09185205901, 09185206901, 09185207901
Latch Lock/Eject Hooks (Short): 09185205911, 09185205913, 09185206911, 09185206913, 09185207903
Latch Holder: 09185206903001

Packaging Considerations:

Bulk Packaging: Most HARTING alternatives available in bulk format for high-volume applications
Tray Packaging: HARTING 09185206903 supplied in tray format for automated assembly processes

Inventory Availability:

HARTING 09185206913 offers the highest inventory level at 2,332 pieces, followed by 09185206901 at 1,004 pieces, providing optimal lead-time assurance for immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can HARTING SEK series connectors directly replace the TE Connectivity 2-281523-0?

A: Yes. All listed HARTING alternatives maintain full electrical and mechanical compatibility across critical parameters: 20-position, 2-row configuration with 2.54mm pitch spacing, through-hole right-angle mounting, shrouded 4-wall construction, solder termination, and UL94 V-0 flammability rating. The contact shape difference (circular to square) does not affect mating compatibility with standard 0.100" (2.54mm) pitch receptacles.

Q: What is the significance of contact post length variation?

A: Contact post length determines solder joint depth and PCB penetration. The main part specifies 0.122" (3.10mm), while substitutes offer 0.177" (4.50mm) or 0.114" (2.90mm). Selection depends on PCB thickness and solder joint requirements. Longer posts (0.177") provide greater mechanical engagement; shorter posts (0.114") suit thin PCB applications.

Q: How do fastening type variants affect application compatibility?

A: Fastening type (Long hooks, Short hooks, or Latch Holder) determines connector retention force and mating/unmating cycles. All variants maintain the same electrical interface and are interchangeable from a functional standpoint. Selection is based on mechanical assembly requirements and cable retention specifications.

Q: Are HARTING alternatives suitable for legacy equipment using the TE Connectivity part?

A: Yes. The electrical and mechanical parameters are equivalent. However, insulation color differs (HARTING parts are gray versus black on the main part). This is a cosmetic distinction with no functional impact. HARTING 09185206903001 is available in black insulation for color-matched applications.

Q: What compliance advantages do HARTING substitutes provide?

A: All HARTING alternatives are ROHS3 compliant and REACH Unaffected, compared to the main part's undefined compliance status. This ensures regulatory compliance for applications subject to environmental directives in EU and other regulated markets.

Q: Which HARTING part offers the best inventory availability?

A: HARTING 09185206913 provides the highest stock level at 2,332 pieces, ensuring immediate availability for high-volume orders. HARTING 09185206901 offers 1,004 pieces as a secondary option.

Q: Can packaging format affect substitution decisions?

A: Yes. HARTING 09185206903 is supplied in tray packaging, suitable for automated pick-and-place assembly. Bulk-packaged alternatives are appropriate for manual assembly or reel-fed processes. Packaging selection depends on manufacturing process requirements.

Q: Is operating temperature specification critical for substitution?

A: The main part does not specify operating temperature. All HARTING alternatives specify -55°C to 125°C operation, providing defined thermal performance. This specification is advantageous for applications requiring temperature-rated component documentation.
