HARTING 09185066321 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The HARTING 09185066321 is an active-status rectangular connector header designed for through-hole, right-angle board-to-cable/wire applications. This 6-position, 2-row connector operates across -55°C to 125°C and features shrouded 4-wall construction with solder termination and latch holder fastening. The part is ROHS3 compliant with UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1). Equivalent substitute parts are necessary to address supply chain flexibility, inventory optimization, and design standardization across manufacturing environments while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the HARTING 09185066321 is determined by strict alignment of the following critical parameters:

Connector Type: Header
Contact Type: Male Pin
Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 6
Number of Rows: 2
Row Spacing - Mating: 0.100" (2.54mm)
Shrouding: Shrouded - 4 Wall
Termination: Solder
Contact Finish - Mating: Gold
Material Flammability Rating: UL94 V-0
RoHS Status: ROHS3 Compliant or RoHS Compliant
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All four substitute parts meet these core electrical and mechanical compatibility criteria. Variations in secondary parameters such as fastening type (latch holder vs. push-pull), contact material composition, post contact length, and insulation height do not preclude functional substitution in standard through-hole applications where the mating interface and board footprint remain identical.

Engineering Selection Recommendations

All four substitute parts maintain active product status and meet the core compliance requirements of the HARTING 09185066321. Selection among these equivalents should be based on the following factors:

TE Connectivity 2-1761605-1 (AMP-Latch Series): Right-angle mounting configuration with push-pull fastening. Rated for 1A per contact at 250VAC. Operating temperature range of -65°C to 105°C provides lower maximum temperature than the original part. ROHS3 compliant with defined electrical ratings.

TE Connectivity 2-1761679-1 (AMP-Latch Series): Vertical through-hole mounting configuration differs from the right-angle requirement of the original part. This substitute is suitable only for applications where vertical orientation is acceptable. ROHS3 compliant with push-pull fastening.

3M 30306-5002HB (303 Series): Right-angle mounting with push-pull fastening. Rated for 1A current. Operating temperature range of -55°C to 105°C aligns with the lower end of the original specification. RoHS compliant (non-ROHS3). Brass contact material provides alternative to copper alloy composition.

Amphenol ICC 75867-131LF (Quickie™ Series): Right-angle mounting with push-pull fastening. Features GXT™ gold finish on mating contacts. RoHS compliant with REACH affected status. Operating temperature range not specified. Thermoplastic insulation material differs from PBT composition.

All parts are MSL 1 (unlimited) and carry UL94 V-0 flammability certification, supporting use in standard industrial and consumer electronics applications.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 2-1761679-1 be used as a direct replacement for HARTING 09185066321?

A: The TE Connectivity 2-1761679-1 features vertical through-hole mounting, whereas the HARTING 09185066321 requires right-angle mounting. Direct PCB footprint substitution is not possible without board redesign. This part is suitable only for applications where vertical connector orientation is acceptable.

Q: What is the primary difference between the fastening mechanisms?

A: The HARTING 09185066321 uses latch holder fastening, while all substitute parts employ push-pull fastening. Both mechanisms provide secure mating and demating. Push-pull fastening is more common in modern connector designs and may offer improved ergonomics in high-cycle applications.

Q: Are there temperature rating differences that affect application suitability?

A: The HARTING 09185066321 operates from -55°C to 125°C. TE Connectivity 2-1761605-1 and 3M 30306-5002HB operate to 105°C maximum, representing a 20°C reduction in upper temperature limit. Amphenol ICC 75867-131LF and TE Connectivity 2-1761679-1 do not specify operating temperature ranges. Applications requiring sustained operation above 105°C should retain the original HARTING part.

Q: Do all substitute parts meet RoHS compliance requirements?

A: TE Connectivity parts are ROHS3 compliant. 3M 30306-5002HB and Amphenol ICC 75867-131LF are RoHS compliant but not specifically ROHS3 certified. For applications requiring ROHS3 certification, TE Connectivity substitutes are preferred.

Q: What contact material differences exist among the substitutes?

A: HARTING uses copper alloy; TE Connectivity and Amphenol ICC use phosphor bronze; 3M uses brass. All materials support gold mating surface finish and are suitable for standard signal and low-power applications. Contact material selection does not affect electrical compatibility for typical PCB interconnect applications.

Q: Are all parts available in equivalent packaging quantities?

A: All parts are supplied in bulk packaging. Inventory levels vary: HARTING 09185066321 (1016 pcs), TE Connectivity 2-1761605-1 (2172 pcs), TE Connectivity 2-1761679-1 (2727 pcs), 3M 30306-5002HB (2430 pcs), and Amphenol ICC 75867-131LF (1417 pcs). Bulk packaging ensures consistent handling and storage across all alternatives.

Q: Can these parts be intermixed on the same PCB assembly?

A: Yes, all parts share identical mating pitch (0.100" / 2.54mm), position count (6), row configuration (2 rows), and shrouded 4-wall construction. PCB footprints are interchangeable for right-angle variants (all except TE Connectivity 2-1761679-1). Mixed-part assemblies are electrically and mechanically compatible.
