Engineering Selection Recommendations

All substitute parts listed are active products from Amphenol ICC (FCI) and maintain full RoHS compliance and MSL 1 rating, matching the environmental and regulatory requirements of the original Molex 0879110411.

Amphenol 68021-104HLF, 68021-204HLF, and 68021-404HLF (BERGSTIK® II Series): These parts differ primarily in contact finish composition and thickness. The 68021-104HLF and 68021-204HLF feature gold or gold GXT™ mating contact finish, while the 68021-404HLF uses tin finish on both mating and post contacts. All three maintain identical pitch, position count, row spacing, and mounting configuration. The 68021-404HLF offers the highest inventory availability at 6448 pieces.

Amphenol 77317-104-04LF and 77317-112-04LF (BERGSTIK® Series): These parts feature breakaway connector type matching the original Molex design. The 77317-112-04LF has a longer mating contact length of 0.268" (6.80mm) compared to 0.230" (5.84mm) in the 77317-104-04LF. Both use gold GXT™ mating contact finish and tin post finish. Operating temperature range extends to 130°C.

Selection among these substitutes depends on specific application requirements regarding contact finish durability, inventory availability, and operating temperature range. All parts are functionally compatible with the Molex 0879110411 in standard board-to-board connector applications.

Frequently Asked Questions (FAQ)

Q: What makes these parts equivalent to the Molex 0879110411?

A: All substitute parts share the critical specifications that determine connector compatibility: 0.100" (2.54mm) pitch, 4 positions in 2 rows with 0.100" row spacing, male pin contacts, square contact shape, through-hole right-angle mounting, solder termination, and UL94 V-0 flammability rating. These parameters ensure mechanical and electrical interchangeability in board-to-board applications.

Q: Are there differences in contact finish between the substitute parts?

A: Yes. The Molex 0879110411 uses gold mating contact finish with copper alloy material. Amphenol substitutes vary: 68021-104HLF and 68021-204HLF offer gold or gold GXT™ finish; 68021-404HLF uses tin finish. The 77317 series uses gold GXT™ mating finish with tin post finish. Contact finish differences do not affect functional compatibility but may influence corrosion resistance in specific environments.

Q: What is the difference between BERGSTIK® II and BERGSTIK® series?

A: Both are Amphenol connector series meeting the same electrical and mechanical specifications for this application. BERGSTIK® II (68021 series) and BERGSTIK® (77317 series) differ in internal design and material composition but maintain identical mating pitch, position count, and mounting configuration. Selection between series depends on inventory availability and specific application requirements.

Q: Can I use the 77317-112-04LF with its longer mating contact length?

A: The 77317-112-04LF has a mating contact length of 0.268" (6.80mm) compared to 0.240" (6.10mm) on the original Molex part. This longer contact length does not prevent functional compatibility in standard board-to-board applications but may affect mating force and insertion depth. Verify mechanical clearance in your specific circuit board design before substitution.

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts are RoHS Compliant with MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance of the original Molex 0879110411.

Q: Which substitute part has the best inventory availability?

A: The Amphenol 68021-404HLF offers the highest inventory with 6448 pieces in stock, followed by 68021-104HLF with 4250 pieces. The original Molex 0879110411 has 897 pieces available.
