Engineering Selection Recommendations

All four substitute parts maintain active product status and meet the core electrical and mechanical requirements of the HARTING 09185347922. Selection among these equivalents depends on application-specific constraints:

71918-034LF (Amphenol ICC / FCI): RoHS compliant with GXT™ gold plating on mating contacts. Mating contact length is 0.228" (5.80mm), which is 0.012" shorter than the main part. Supplied in tube packaging. Operating temperature range not specified in available data.

D3431-6002-AR (3M D3000): ROHS3 compliant with 1.75A current rating specified. Operating temperature range is -55°C to 105°C, which is 20°C lower than the main part's upper limit. Supplied in tray packaging. Contact material is brass rather than copper alloy.

N3431-6002RB (3M 3000): ROHS3 compliant with 1.75A current rating and copper alloy contact material. Operating temperature range is -55°C to 105°C. Post contact length is 0.112" (2.84mm), significantly shorter than the main part's 0.177" (4.50mm). Supplied in tray packaging.

N3431-6003RB (3M 3000): ROHS3 compliant with 1.75A current rating and copper alloy contact material. Operating temperature range is -55°C to 105°C. Post contact length is 0.155" (3.94mm), closer to the main part specification. Supplied in bulk packaging, matching the main part's packaging format.

Frequently Asked Questions (FAQ)

Q: Can I use 71918-034LF as a direct replacement for HARTING 09185347922?

A: 71918-034LF meets all critical substitution parameters including position count, pitch, shrouding, and contact finishes. However, the mating contact length differs by 0.012" (0.30mm). Compatibility depends on your specific PCB and mating connector design. Verify contact engagement depth in your application.

Q: What is the difference between the 3M 3000 series parts (N3431-6002RB and N3431-6003RB)?

A: Both are ROHS3 compliant 3M 3000 series headers with identical electrical specifications. The primary difference is post contact length: N3431-6002RB has 0.112" (2.84mm) posts, while N3431-6003RB has 0.155" (3.94mm) posts. Select based on your PCB thickness and solder joint requirements.

Q: Does the operating temperature difference affect substitution?

A: The HARTING part operates to 125°C, while 3M and Amphenol parts are specified to 105°C or unspecified. If your application requires operation above 105°C, the HARTING 09185347922 is the appropriate choice. For applications below 105°C, substitutes are suitable.

Q: Are there packaging considerations when selecting a substitute?

A: Yes. HARTING 09185347922 and N3431-6003RB are supplied in bulk packaging. 71918-034LF comes in tube packaging, while D3431-6002-AR and N3431-6002RB are supplied in trays. Packaging affects handling, storage, and integration into assembly processes.

Q: What is the significance of contact material differences?

A: All parts use gold-plated mating contacts and tin-plated posts. The underlying contact material varies: HARTING and N3431 series use copper alloy, 71918-034LF uses phosphor bronze, and D3431-6002-AR uses brass. These materials provide equivalent electrical performance and corrosion resistance for standard applications.

Q: Is the insulation color difference (gray vs. black) functionally significant?

A: No. Insulation color is a visual identifier only and does not affect electrical or mechanical performance. HARTING uses gray insulation, while 3M parts use black. This is a cosmetic distinction.
