3M 2304-6111-TG Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The 3M 2304-6111-TG is a through-hole rectangular connector header with 4 positions at 0.100" (2.54mm) pitch. This unshrouded, single-row header is designed for board-to-board or cable connections with solder termination and push-pull fastening. The part is currently active in production with 849 units in stock.

Equivalent and substitute parts are necessary when the original 3M 2304-6111-TG becomes unavailable, when design requirements demand alternative compliance certifications (such as RoHS3 compliance), or when sourcing from multiple manufacturers is required for supply chain resilience.

Substitute Part Grouping Explanation

Substitution eligibility for the 3M 2304-6111-TG is determined by the following mandatory parameters:

Pitch - Mating: 0.100" (2.54mm)
Number of Positions: 4
Number of Rows: 1
Connector Type: Header
Contact Type: Male Pin
Mounting Type: Through Hole
Termination: Solder
Fastening Type: Push-Pull

Parts meeting these core electrical and mechanical parameters are functionally equivalent. Secondary parameters such as contact finish, contact material, insulation material, and operating temperature range may vary within acceptable tolerances for the 2.54mm pitch header category. Compliance status (RoHS, REACH) and product status (Active, Obsolete) are documented but do not disqualify functional equivalence.

Engineering Selection Recommendations

For Active Production Designs:

Select from Molex 0022284040, Molex 0022284046, Mill-Max 350-10-104-00-006000, Amphenol ICC 68000-204HLF, Amphenol ICC 68000-404HLF, Amphenol ICC 68001-104HLF, Amphenol ICC 68001-204HLF, or Amphenol ICC 77311-101-04LF. All are currently active in production and meet the core 2.54mm pitch, 4-position header specification.

For RoHS3 Compliance Requirements:

If RoHS3 compliance is mandatory, select from Molex 0022284040, Molex 0022284046, Mill-Max 350-10-104-00-006000, Amphenol ICC 68000-204HLF, Amphenol ICC 68000-404HLF, Amphenol ICC 68001-104HLF, Amphenol ICC 68001-204HLF, or Amphenol ICC 69190-404. The original 3M 2304-6111-TG is RoHS non-compliant.

For Extended Temperature Range:

Amphenol ICC BERGSTIK® II and BERGSTIK® series parts (68000-204HLF, 68000-404HLF, 68001-104HLF, 68001-204HLF, 69190-404, 77311-101-04LF) support -65°C to 125°C or -65°C to 130°C operating ranges, exceeding the original part's -55°C to 105°C specification.

For Gold Mating Contact Finish:

Molex 0022284046, Mill-Max 350-10-104-00-006000, Amphenol ICC 68000-204HLF, Amphenol ICC 68001-104HLF, Amphenol ICC 68001-204HLF, and Amphenol ICC 77311-101-04LF provide gold mating contact finish matching the original 3M part.

For Tin Mating Contact Finish:

Molex 0022284040, Amphenol ICC 68000-404HLF, and Amphenol ICC 69190-404 provide tin mating contact finish as an alternative.

Avoid for New Designs:

TE Connectivity 4-103185-0-04 and Amphenol ICC 69190-404 are obsolete and should not be selected for new production designs.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 3M 2304-6111-TG with any of these parts directly?

A: Yes, all listed parts are functionally equivalent for the core application of a 4-position, 2.54mm pitch through-hole header with solder termination and push-pull fastening. Physical board layout and mating connector compatibility must be verified, as contact length and insulation height may vary slightly between manufacturers.

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

A: Gold provides superior corrosion resistance and lower contact resistance over extended storage and environmental exposure. Tin is a cost-effective alternative suitable for controlled indoor environments. The original 3M part uses gold; equivalent performance is available from Molex 0022284046 and Amphenol ICC parts with gold finish.

Q: Why is the original 3M 2304-6111-TG RoHS non-compliant?

A: The part contains tin-lead solder on the post termination, which exceeds RoHS lead content limits. RoHS3-compliant alternatives such as Molex 0022284040 and 0022284046 use lead-free termination materials.

Q: Does contact material (copper alloy vs. phosphor bronze vs. brass alloy) affect compatibility?

A: Contact material affects electrical conductivity, spring characteristics, and long-term reliability but does not prevent mechanical or electrical mating. Phosphor bronze (used in Amphenol ICC parts) and copper alloy (used in 3M and TE Connectivity parts) are both suitable for 3A current ratings at 2.54mm pitch. Brass alloy (Mill-Max) is also acceptable for this application class.

Q: Can I use the TE Connectivity 4-103185-0-04 or Amphenol ICC 69190-404 in new designs?

A: Both parts are obsolete and should not be selected for new production designs. Use active parts such as Molex, Mill-Max, or current Amphenol ICC BERGSTIK® II series instead.

Q: What is the significance of the operating temperature range difference?

A: The original 3M part operates from -55°C to 105°C. Amphenol ICC BERGSTIK® series parts extend this to -65°C to 125°C or -65°C to 130°C. If your application requires operation below -55°C or above 105°C, select an Amphenol ICC part with the extended range.

Q: Are there packaging differences I should consider?

A: Yes. The original 3M part is supplied in bulk packaging. Molex parts are bulk, Mill-Max is tube, Amphenol ICC BERGSTIK® II parts are bag, and Amphenol ICC BERGSTIK® parts are bulk. Packaging does not affect electrical or mechanical performance but may impact procurement, handling, and inventory management.

Q: Which substitute offers the best inventory availability?

A: Amphenol ICC 68001-204HLF has 15,008 units in stock, Molex 0022284046 has 18,133 units, and Molex 0022284040 has 15,263 units. These three parts offer the highest stock levels for immediate availability.
