Engineering Selection Recommendations

All substitute parts listed maintain the core electrical and mechanical specifications required for direct replacement of the 3M 2316-6121-TP. Selection among substitutes should be based on the following criteria:

RoHS Compliance: The original 3M 2316-6121-TP is RoHS non-compliant. All listed substitutes from Molex and Amphenol ICC (FCI) are RoHS compliant, making them suitable for applications requiring RoHS certification.

Operating Temperature Range: The 3M part operates from -55°C to 105°C. Amphenol ICC (FCI) BERGSTIK® and BERGSTIK® II series parts extend the upper temperature limit to 125°C or 130°C, providing enhanced thermal performance for demanding applications.

Contact Material: The original part uses Copper Alloy contacts. Amphenol ICC (FCI) substitutes employ Phosphor Bronze, which offers improved durability and contact reliability. Molex C-Grid 70280 series maintains Copper Alloy contacts.

Contact Finish Options: Substitutes are available with Tin, Gold, or Gold GXT™ finishes. Gold-plated variants (0010897162, 67996-116HLF, 67996-216HLF, 67997-116HLF, 67997-216HLF, 68602-116HLF) provide enhanced corrosion resistance and are suitable for high-reliability applications. Tin-finished variants (67996-416HLF, 67997-416HLF) offer cost-effective alternatives.

Post Length Variations: Amphenol ICC (FCI) BERGSTIK® II series offers three post length options (0.095", 0.120", 0.150") to accommodate different PCB thicknesses and assembly requirements. The 68602-116HLF variant with 0.150" post length is suitable for thicker board assemblies.

Inventory Availability: Amphenol ICC (FCI) BERGSTIK® II series parts (67996-416HLF, 67997-116HLF, 67997-216HLF) have the highest inventory levels, supporting immediate procurement needs.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0010897161 or 0010897162 directly replace the 3M 2316-6121-TP?

A: Yes. Both Molex parts maintain the same 16-position, 2-row configuration at 0.100" pitch with identical mounting type, termination, and fastening specifications. The Molex C-Grid 70280 series is electrically and mechanically compatible. The primary differences are contact material (Copper Alloy vs. Copper Alloy), contact finish (Tin or Gold vs. Tin-Lead), and insulation material (LCP vs. Thermoplastic, Glass Filled). Both are RoHS3 compliant.

Q: What is the difference between the Amphenol ICC (FCI) 67996 and 67997 series?

A: Both are BERGSTIK® II headers with identical electrical and mechanical specifications. The primary difference is post length: 67996 series has 0.095" post length, while 67997 series has 0.120" post length. The 67997 series matches the original 3M part's post length and overall contact length (0.450"). Select based on PCB thickness and assembly requirements.

Q: Which substitute offers the best corrosion resistance?

A: Amphenol ICC (FCI) parts with Gold or Gold GXT™ contact finish (67996-116HLF, 67996-216HLF, 67997-116HLF, 67997-216HLF, 68602-116HLF) provide superior corrosion resistance compared to Tin or Tin-Lead finishes. Gold plating is recommended for applications exposed to moisture, salt spray, or harsh environmental conditions.

Q: Is the 68602-116HLF suitable for thick PCB assemblies?

A: Yes. The 68602-116HLF features a 0.150" post length (compared to 0.120" on the original part), making it suitable for PCB thicknesses up to approximately 0.150". This variant is ideal for applications requiring deeper board penetration or multi-layer PCB assemblies.

Q: Are all substitutes rated for 3A current?

A: Yes. All listed substitutes maintain the 3A current rating per contact, ensuring electrical compatibility with the original 3M 2316-6121-TP for standard applications.

Q: What is the difference between Tin and Gold contact finishes in terms of cost and performance?

A: Tin-finished contacts (67996-416HLF, 67997-416HLF) are cost-effective and suitable for general-purpose applications with standard environmental conditions. Gold-finished contacts provide enhanced corrosion resistance, lower contact resistance, and improved reliability in high-reliability, automotive, medical, and telecommunications applications. Gold finishes command a price premium but extend component lifespan in demanding environments.

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

A: All listed substitutes are mechanically and electrically compatible with each other due to identical pitch, position count, and connector geometry. However, for consistency and supply chain management, it is recommended to standardize on a single part number per assembly to ensure uniform performance and simplify inventory control.
