HARTING 09185346911 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The HARTING 09185346911 is a shrouded right-angle rectangular connector header with 34 positions at 2.54mm pitch, designed for through-hole solder termination in board-to-cable/wire applications. This SEK series component features male pins with gold-plated mating contacts and tin-plated posts, operating across -55°C to 125°C. The part is active and ROHS3 compliant with 1,116 units in current inventory.

Equivalent and substitute parts are identified when design requirements permit tolerance of minor variations in contact post length, insulation height, contact finish specifications, or operating temperature ranges, while maintaining core electrical and mechanical compatibility across the 34-position, 2.54mm pitch, shrouded header configuration.

Engineering Selection Recommendations

ROHS3 Compliant Substitutes: Parts 5102322-8, 5499141-8, 5499786-8, 5499913-8, D3431-5202-AR, D3431-5302-AR, N3431-5202RB, and N3431-5302RB all meet ROHS3 compliance matching the original HARTING 09185346911. Part 499141-8 is RoHS non-compliant and should be selected only where legacy or non-regulated applications permit.

Temperature Operating Range: The HARTING 09185346911 operates to 125°C. All TE Connectivity and 3M substitutes operate to 105°C maximum. Selection of substitutes is appropriate for applications with maximum operating temperatures at or below 105°C.

Contact Post Length Variation: The original part features 0.177" post length. Substitutes range from 0.110" to 0.155". Post length affects board-level clearance and solder joint geometry. Verify PCB design accommodates the shorter post lengths of substitute parts before selection.

Fastening Mechanism: The original part uses short latch hooks. Substitutes with long latch hooks (5102322-8, 5499141-8, 5499786-8, D3431-5302-AR, N3431-5302RB) provide enhanced mating force retention. Short hook variants (5499913-8, D3431-5202-AR, N3431-5202RB) match the original fastening behavior.

Packaging Format: Bulk packaging (original, 499141-8, 5499786-8, 5499913-8, N3431-5202RB, N3431-5302RB) and Tray packaging (5102322-8, 5499141-8, D3431-5202-AR, D3431-5302-AR) are available. Tray packaging is standard for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can I substitute a part with shorter contact post length? A: Yes, if your PCB design accommodates the reduced post length. The original 09185346911 has 0.177" posts; most substitutes have 0.110" to 0.155" posts. Verify clearance to adjacent components and solder joint formation before substitution.

Q: What is the difference between short and long latch hooks? A: Short latch hooks (original part) provide standard mating retention force. Long latch hooks (available on most substitutes) provide enhanced retention and are preferred for high-vibration or high-shock applications. Both are mechanically compatible with standard 34-position 2.54mm pitch receptacles.

Q: Are all substitutes RoHS compliant? A: Most substitutes are ROHS3 compliant. Part 499141-8 is RoHS non-compliant. Verify compliance requirements for your application before selection.

Q: Can I use a substitute rated for 105°C maximum in a 125°C application? A: No. The original HARTING part is rated to 125°C. If your application requires operation above 105°C, the original part or equivalent high-temperature rated alternatives must be used. All listed substitutes are limited to 105°C maximum.

Q: What is the difference between TE Connectivity AMP-Latch and 3M D3000 series? A: Both are 34-position 2.54mm pitch shrouded headers with equivalent electrical and mechanical function. AMP-Latch parts use brass contacts; D3000 and 3000 series use brass or copper alloy contacts. Contact finish specifications and insulation material differ slightly. Both are industry-standard alternatives suitable for board-to-cable applications.

Q: Does packaging (Bulk vs. Tray) affect electrical performance? A: No. Bulk and Tray packaging formats contain identical connector components. Packaging selection is driven by assembly process requirements and inventory management. Tray packaging is standard for automated pick-and-place assembly; Bulk packaging is suitable for manual assembly or reel-based processes.

Q: Can I mix fastening types (short and long hooks) in the same assembly? A: Yes, if the mating receptacle design accommodates both hook lengths. However, for consistency and predictable mating force across all connectors in a system, use uniform fastening types throughout the assembly.
