Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

Molex C-Grid 70280 series (0010897060, 0010897061, 0010897062, 0010977066) and Molex C-Grid 87914 series (0879140613, 0879140616) are direct functional equivalents. These parts maintain identical pitch, position count, row configuration, and mounting specifications. All are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 classification. Contact finish variations (gold or tin) are acceptable for electrical performance. Molex parts feature Liquid Crystal Polymer insulation with glass fill, providing enhanced mechanical and thermal properties compared to thermoplastic insulation. These substitutes are suitable for applications where the main part is unavailable.

Secondary Substitutes (Acceptable with Design Verification):

TE Connectivity AMPMODU Mod II series (1-87215-2, 5-146250-3) maintains all critical electrical and mechanical parameters. These parts feature phosphor bronze or copper alloy contacts with equivalent current ratings (3A). Operating temperature range for TE parts extends to -65°C minimum but is limited to 105°C maximum, which is acceptable for most applications but does not match the 130°C upper limit of the main part. Contact shape differs (circular vs. square), but this does not affect electrical interchangeability. RoHS compliance is confirmed. These substitutes are suitable for general purpose, automotive, medical, and telecommunications applications.

Limited Substitutes (Application-Specific Considerations):

3M 2300 series (2306-6221-TG) is electrically equivalent but carries RoHS non-compliant status, making it unsuitable for applications requiring RoHS compliance. Operating temperature range (-55°C ~ 105°C) does not meet the -65°C minimum requirement of the main part. This substitute is acceptable only for legacy systems or applications without RoHS mandates and with operating temperatures above -55°C.

Inventory Availability:

TE Connectivity 5-146250-3 offers the highest inventory availability (50020 units), followed by Molex 0879140616 (22155 units) and Molex 0010977066 (11708 units). These options provide supply chain flexibility for high-volume production requirements.

Frequently Asked Questions (FAQ)

Q: Can I use a Molex C-Grid 70280 connector in place of the Amphenol ICC 77313-124R06LF?

A: Yes. Molex C-Grid 70280 series connectors (0010897060, 0010897061, 0010897062, 0010977066) are direct functional equivalents. All critical parameters match: 6-position, 2-row configuration with 0.100" (2.54mm) pitch, through-hole mounting, male pin contacts, push-pull fastening, and UL94 V-0 flammability rating. Contact finish and material variations are acceptable for electrical performance.

Q: What is the difference between kinked pin and straight solder termination?

A: Kinked pin termination provides mechanical retention during PCB assembly, reducing the risk of pin migration during soldering. Straight solder termination relies solely on solder joint integrity. Both termination methods are acceptable for this connector category provided proper soldering techniques are employed. The main part features kinked pin termination, while most substitutes use straight solder termination.

Q: Are Molex and TE Connectivity connectors interchangeable with the Amphenol ICC part?

A: Yes, within the specified parameter ranges. Molex C-Grid and TE Connectivity AMPMODU Mod II series maintain identical pitch, position count, row spacing, and mounting type. Contact material and insulation material variations do not affect electrical interchangeability. Physical dimensions may vary slightly; verify contact length and insulation height for specific PCB designs.

Q: Does the operating temperature range affect substitution?

A: The main part operates from -65°C to 130°C. Molex substitutes do not specify operating temperature but are rated for industrial applications. TE Connectivity parts are rated -65°C to 105°C, which covers most applications but does not reach the 130°C upper limit. For applications requiring operation above 105°C, the main part or Molex alternatives are recommended. For applications below 105°C, TE Connectivity substitutes are acceptable.

Q: Can I use the 3M 2300 series connector as a substitute?

A: The 3M 2306-6221-TG is electrically equivalent but has two limitations: RoHS non-compliant status and operating temperature range of -55°C to 105°C. Use this substitute only for legacy systems without RoHS requirements and where operating temperatures remain above -55°C.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. RoHS Compliant refers to the original 2006 directive, while ROHS3 Compliant refers to the 2011 recast directive with expanded substance restrictions. ROHS3 compliance is more stringent and is preferred for new designs. All Molex substitutes carry ROHS3 designation, providing enhanced environmental compliance.

Q: Which substitute offers the best inventory availability?

A: TE Connectivity 5-146250-3 provides the highest inventory (50020 units), followed by Molex 0879140616 (22155 units). For immediate availability with minimal lead time, these options are recommended.

Q: Are contact finish variations (gold vs. tin) significant for substitution?

A: Contact finish variations do not affect electrical interchangeability for this connector category. Gold finish provides superior corrosion resistance and is preferred for high-reliability applications. Tin finish is acceptable for general purpose applications. Both finishes maintain equivalent contact resistance and current-carrying capacity at the specified 3A rating.
