• Connector Interface: 8 positions, 4.6mm pitch, 90° right-angle orientation, male pins with 4-side shrouding
• Electrical Performance: UL voltage rating of 300V and current capacity sufficient for the application
• Mounting Configuration: Through-hole solder termination on PCB
• Compliance: RoHS3 compliance and UL94 V-0 flammability rating
• Contact System: Tin-plated mating finish for corrosion resistance

All substitute parts listed maintain these core specifications, ensuring mechanical and electrical interchangeability within the specified operating parameters.

Parameter Comparison

Engineering Selection Recommendations

14120814002000 (HARTING har-flexicon®): This substitute provides higher current capacity (11A UL) and extended operating temperature range (-40°C to 110°C). It maintains UL94 V-0 compliance and RoHS3 certification. Housing material differs (Polyamide/Nylon vs. PBT), but electrical and mechanical interfaces remain compatible.

691322110008 (Würth Elektronik WR-TBL Series 3221): This option offers 10A UL current rating and operates across -40°C to 105°C. It is RoHS3 compliant with UL94 V-0 rating. Note that REACH status is listed as affected, requiring compliance verification for specific applications. Housing material is Polyamide (PA66).

OQ0812510000G (Amphenol Anytek 06-350): This substitute delivers 10A UL current capacity and the widest operating temperature range (-40°C to 115°C). It maintains RoHS3 compliance and UL94 V-0 flammability rating. Housing material is thermoplastic resin, compatible with the original specification.

OSTOQ081251 (On Shore Technology OSTOQ): This part meets the 300V UL voltage requirement and operates from -30°C to 105°C. RoHS3 compliance is confirmed. Flammability rating and current capacity are not specified in available data, requiring datasheet verification before selection for current-critical applications.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably with the 1843855?

A: Yes, all listed substitutes maintain the same 8-position, 4.6mm pitch, 90° right-angle connector interface with male pins and 4-side shrouding. They are electrically and mechanically compatible for through-hole solder mounting applications operating at 300V UL.

Q: What is the significance of the current rating differences?

A: The 1843855 is rated at 8A (UL). Substitute parts with higher current ratings (10A or 11A) provide additional design margin and are suitable for applications requiring the original 8A specification. Lower current ratings would not be acceptable substitutes.

Q: Are there differences in operating temperature ranges?

A: Yes. The 1843855 does not specify an operating temperature range. Substitutes range from -30°C to 115°C depending on manufacturer. Selection should be based on the specific thermal requirements of the application.

Q: What does RoHS3 compliance mean for these parts?

A: RoHS3 compliance indicates that the parts meet Restriction of Hazardous Substances Directive requirements, restricting the use of specific hazardous materials. All listed substitutes are RoHS3 compliant, ensuring regulatory alignment.

Q: Does housing material affect compatibility?

A: Housing material differences (PBT, Polyamide, Thermoplastic Resin) do not affect electrical or mechanical interface compatibility. Material selection may influence thermal performance and mechanical durability in specific environmental conditions.

Q: What is the Moisture Sensitivity Level (MSL)?

A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special handling or storage conditions. The 691322110008 lists MSL as Not Applicable, indicating similar unrestricted handling.

Q: Should I verify REACH compliance before selection?

A: The 691322110008 is listed as REACH Affected. If your application or region requires REACH compliance verification, consult the manufacturer's documentation or compliance statement before final part selection.
