Frequently Asked Questions (FAQ)

Q: Can the Molex C-Grid 70280 series parts directly replace the TE Connectivity 1-146220-2?

A: Yes. The Molex C-Grid 70280 series (parts 0010897060, 0010897061, 0010897062) meet all critical mating parameters: 0.100" (2.54mm) pitch, 6 positions in 2 rows, square male pin contacts, through-hole solder termination, and push-pull fastening. All positions are loaded in the Molex variants, whereas the original TE part has 5 of 6 positions loaded. Electrical ratings (3A current, UL94 V-0 flammability) are equivalent or superior.

Q: What is the difference between the Molex C-Grid 70280 and C-Grid 70287 series?

A: The primary difference is termination style. C-Grid 70280 series (0010897060, 0010897061, 0010897062) features standard solder posts. C-Grid 70287 series (0702871001, 0702871099) features kinked pin termination, which provides enhanced mechanical retention during PCB assembly and wave soldering processes. Both series maintain identical mating interface dimensions and electrical specifications.

Q: Are there RoHS compliance differences between substitute options?

A: Yes. Molex C-Grid series (0010897060, 0010897061, 0010897062, 0702871001, 0702871099) and Amphenol ICC 67996-106HLF are ROHS3 or RoHS compliant. The 3M 2300 series (2306-6121-TB, 2306-6121-TG, 2306-6121-TP) and original TE part are RoHS non-compliant. For applications subject to RoHS regulations, Molex or Amphenol ICC alternatives are required.

Q: What is the significance of contact finish thickness variations?

A: Contact finish thickness affects durability and corrosion resistance but does not impact electrical compatibility. Gold-plated contacts with 30.0µin (0.76µm) thickness (Molex 0010897060) provide superior corrosion resistance compared to 15.0µin (0.38µm) thickness (Molex 0010897062). Tin-plated contacts (150.0µin / 3.81µm) offer cost reduction with acceptable performance for non-corrosive environments. Selection depends on application environment and cost constraints.

Q: Can parts with different insulation materials be substituted?

A: Yes, provided electrical and mechanical specifications remain equivalent. The original TE part uses thermoplastic insulation. Molex C-Grid series use liquid crystal polymer (LCP) glass-filled insulation, which provides superior dimensional stability and temperature performance. The 3M 2300 series uses thermoplastic glass-filled insulation, maintaining material consistency with the original part. All materials meet UL94 V-0 flammability requirements.

Q: What is the impact of post length variations on PCB assembly?

A: Post length affects solder joint formation and PCB penetration depth. The original TE part has 0.090" (2.29mm) posts. Molex C-Grid 70280 series has 0.107" (2.71mm) posts, and C-Grid 70287 series has 0.125" (3.18mm) posts. Extended post length (0702800591 at 0.175" / 4.45mm) accommodates thicker PCBs or provides enhanced mechanical retention. Standard post lengths (0.107" to 0.125") are suitable for typical PCB thicknesses (0.062" to 0.093").

Q: Is the Amphenol ICC 67996-106HLF suitable for high-temperature applications?

A: Yes. The Amphenol ICC 67996-106HLF operates across -65°C ~ 125°C, exceeding the original TE part specification (-65°C ~ 105°C) and most Molex alternatives. Phosphor bronze contact material provides superior corrosion resistance and maintains contact force stability across the extended temperature range. This part is recommended for applications requiring enhanced thermal performance.

Q: What inventory considerations should guide part selection?

A: Amphenol ICC 67996-106HLF has the highest inventory availability (9,309 units), followed by Molex 0010897062 (5,278 units) and Molex 0702871001 (2,362 units). For applications requiring immediate availability, these parts are preferred. Molex 0702800591 (745 units) and 3M variants (649-1,118 units) have lower inventory levels and longer lead times.
