HARTING 09185205909 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The HARTING 09185205909 is a through-hole rectangular connector header with 20 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and procurement continuity. The connector features shrouded 4-wall construction with press-fit and solder termination options, gold-plated mating contacts, and latch lock/eject hook fastening.

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09185205909 is determined by strict alignment of the following critical parameters:

• Connector Type & Contact Configuration: Header with male pins
• Position Count & Row Arrangement: 20 positions in 2 rows
• Pitch Specification: 0.100" (2.54mm) mating pitch and row spacing
• Shrouding & Mechanical Form Factor: Shrouded 4-wall construction
• Mounting Method: Through-hole PCB mounting
• Contact Interface: Gold-plated mating surface
• Fastening Mechanism: Latch lock/eject hooks, long style

Two substitute parts meet these criteria:

1. HARTING 09185205902 - Same manufacturer, active product status, identical electrical and mechanical specifications with simplified termination (solder only)
2. 3M N3428-630T02RB - Cross-manufacturer equivalent from 3M's 3000 series, maintains all critical parameters with documented current rating specification

Parameter Comparison

Engineering Selection Recommendations

HARTING 09185205902 is the primary substitute for the obsolete 09185205909. Both components are from the same manufacturer's SEK series, share identical electrical and mechanical specifications, and maintain full ROHS3 compliance. The 09185205902 holds active product status with 1052 units in stock, ensuring procurement availability. The primary difference is termination method: the substitute offers solder termination only, whereas the original supported both press-fit and solder options. This represents a functional simplification suitable for standard PCB assembly processes.

3M N3428-630T02RB serves as a cross-manufacturer alternative from the 3000 series. This component maintains all critical dimensional and electrical parameters with documented operating temperature range (-55°C ~ 105°C) and current rating (1.75A). The N3428-630T02RB supports both press-fit and solder termination, matching the original part's flexibility. Insulation color differs (black versus gray), and operating temperature maximum is 20°C lower than the HARTING substitute. This option is appropriate when cross-manufacturer qualification is acceptable and press-fit termination capability is required.

Both substitutes carry ROHS3 compliance, unlimited moisture sensitivity rating, and identical contact pitch and position configuration. Selection between them depends on termination method requirements and manufacturer preference within design qualification parameters.

Frequently Asked Questions (FAQ)

Q: Can HARTING 09185205902 directly replace the obsolete 09185205909 in existing designs?

A: Yes. The 09185205902 maintains identical mating pitch (0.100"), position count (20 in 2 rows), shrouding configuration (4-wall), contact geometry, and gold-plated mating surface. The primary design consideration is termination method: the substitute uses solder termination only, eliminating press-fit capability. If your PCB assembly process relies exclusively on solder attachment, direct substitution is valid. If press-fit termination is required, the 3M N3428-630T02RB preserves this option.

Q: What are the dimensional differences between the three parts?

A: Contact post length varies slightly: the main part specifies 0.177" (4.50mm), the HARTING substitute maintains this specification, while the 3M part measures 0.175" (4.45mm). Overall contact length differences are similarly minimal (0.713" to 0.715"). Insulation height ranges from 0.680" to 0.690". These variations fall within standard manufacturing tolerances and do not affect mating compatibility or PCB footprint requirements.

Q: Are there compliance or certification differences?

A: All three parts are ROHS3 compliant with unlimited moisture sensitivity (MSL 1). The HARTING 09185205902 and 3M N3428-630T02RB both specify UL94 V-0 material flammability rating, whereas the original part does not document this specification. Both substitutes provide documented operating temperature ranges; the original does not. The 3M part includes a documented current rating of 1.75A.

Q: Which substitute should I select for new designs?

A: For new designs, HARTING 09185205902 is recommended as the primary choice due to same-manufacturer continuity, active product status, and identical specifications to the original. If your design requires press-fit termination capability or cross-manufacturer qualification, the 3M N3428-630T02RB is functionally equivalent with documented electrical ratings.

Q: Does insulation color affect electrical performance or compatibility?

A: No. Insulation color (gray for HARTING parts, black for 3M) is a visual identifier only and does not affect electrical performance, mating compatibility, or PCB assembly. Selection based on color preference is valid for design documentation or assembly traceability purposes.

Q: What is the inventory status for these substitutes?

A: HARTING 09185205902 has 1052 units in stock. 3M N3428-630T02RB has 908 units in stock. Both are actively manufactured and available for procurement.
