Engineering Selection Recommendations

Molex KK254 Series (0022284022, 0022284024, 0022284027, 0022284028, 0022285024, 0022285027): These Molex KK254 and 42375 series headers provide direct functional equivalence to the 3M 2302-6211-TP. All variants are ROHS3 compliant, addressing regulatory requirements where RoHS compliance is mandated. Contact finish options include tin and gold plating at varying thicknesses. The KK254 series maintains the required 2.54mm pitch, 2-position, unshrouded configuration with square male pins and solder termination. Insulation height is 0.090" (2.29mm), slightly lower than the original part. These connectors are suitable for general purpose, automotive, medical, and telecommunications applications.

Molex C-Grid III 90120 Series (0901200122, 0901200762, 0901200922): The C-Grid III 90120 series offers extended operating temperature range (-55°C to 125°C) compared to the 3M original (-55°C to 105°C). These headers maintain the 2.54mm pitch and 2-position configuration with unshrouded, square male pin design. Contact finish options include tin and gold plating. The insulation height is 0.098" (2.50mm). All variants are ROHS3 compliant. This series is suitable for automotive and general purpose applications requiring enhanced thermal performance.

Amphenol ICC (FCI) BERGSTIK® 75160-327-02LF: The BERGSTIK® series provides an alternative from a different manufacturer with RoHS compliance. This part features tin contact finish, maintains the 2.54mm pitch and 2-position configuration, and offers an extended operating temperature range (-65°C to 130°C). The insulation height matches the original at 0.100" (2.54mm). This connector is currently obsolete in production status. The contact length is 0.260" (6.60mm), representing the shortest mating contact length among available substitutes.

Selection Criteria:

For RoHS3 compliance requirements: Select from Molex KK254, C-Grid III 90120, or Amphenol ICC BERGSTIK® series
For extended temperature operation: Select Molex C-Grid III 90120 or Amphenol ICC BERGSTIK® series
For gold contact finish: Select Molex variants with gold plating (0022284024, 0022284027, 0022284028, 0022285024, 0022285027, 0901200762, 0901200922)
For tin contact finish: Select Molex 0022284022, 0901200122, or Amphenol ICC 75160-327-02LF
For highest inventory availability: Molex 0022285027 (118,616 units)

Frequently Asked Questions (FAQ)

Q: Can I substitute the 3M 2302-6211-TP with any of the listed Molex KK254 series connectors?

A: Yes. All Molex KK254 series variants (0022284022, 0022284024, 0022284027, 0022284028, 0022285024, 0022285027) are electrically and mechanically compatible. They maintain the required 2.54mm pitch, 2-position configuration, unshrouded design, and solder termination. Differences exist in contact finish (tin or gold) and contact length specifications, which fall within allowable variation parameters.

Q: What is the difference between tin and gold contact finishes?

A: Tin contact finish provides standard electrical conductivity and is suitable for general applications. Gold contact finish offers superior corrosion resistance and lower contact resistance, making it preferable for applications requiring enhanced reliability or exposure to corrosive environments. Gold-plated variants are available at 15.0µin (0.38µm) and 30.0µin (0.76µm) thicknesses.

Q: Does the Molex C-Grid III 90120 series offer better performance than the KK254 series?

A: The C-Grid III 90120 series extends the operating temperature range to -55°C to 125°C, compared to the KK254 series which does not specify an operating temperature range. Both series maintain the same pitch, position count, and termination method. Selection depends on thermal requirements of the application.

Q: Is the Amphenol ICC BERGSTIK® 75160-327-02LF still available for new designs?

A: The BERGSTIK® series is listed as obsolete in production status. While 1,161 units are currently in inventory, this part should not be selected for new designs. Molex KK254 or C-Grid III 90120 series are recommended for ongoing production.

Q: What does RoHS compliance mean for connector selection?

A: RoHS (Restriction of Hazardous Substances) compliance indicates the connector meets regulatory requirements restricting lead, cadmium, mercury, and other hazardous materials. The original 3M 2302-6211-TP is RoHS non-compliant. All Molex and Amphenol ICC substitutes listed are RoHS compliant (ROHS3 or RoHS Compliant), making them suitable for applications requiring regulatory compliance.

Q: Are there differences in insulation material between substitute options?

A: Yes. The 3M original uses thermoplastic glass-filled insulation. Molex KK254 and C-Grid III 90120 series use polyamide (PA) nylon glass-filled or polyester glass-filled insulation. Amphenol ICC BERGSTIK® uses thermoplastic insulation. All materials meet UL94 V-0 flammability requirements and are functionally equivalent for the specified application.

Q: Can I mix different substitute parts in the same assembly?

A: All listed substitutes maintain the same 2.54mm pitch and 2-position configuration, allowing them to mate with the same receptacle connectors. However, for consistency in manufacturing and quality control, it is recommended to standardize on a single substitute part number within an assembly or product line.

Q: What is the significance of contact length variations?

A: Contact length variations (0.260" to 0.320" mating contact length) affect the depth of insertion and mating force characteristics. These variations fall within acceptable parameters for the 2.54mm pitch header category. Selection should be based on the corresponding receptacle connector specifications to ensure proper mating depth and contact engagement.
