Molex 0879140416 Rectangular Connector Header - Equivalent & Substitute Parts

Part Overview

The Molex 0879140416 is a through-hole rectangular connector header with 4 positions arranged in 2 rows at 0.100" (2.54mm) pitch. This connector is classified as a board-to-board or cable interface component with male pin contacts, solder termination, and push-pull fastening. The part maintains Active product status with 1,093 units in current inventory.

Substitute parts become necessary when the primary part experiences supply constraints, when design revisions require alternative contact materials or finishes, or when system requirements demand different electrical or mechanical specifications within the allowable parameter range for this connector category.

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0879140416 is determined by strict alignment of the following core parameters:

Mating pitch: 0.100" (2.54mm) - exact match required
Number of positions: 4 - exact match required
Row configuration: 2 rows at 0.100" (2.54mm) spacing - exact match required
Contact type: Male pin - exact match required
Mounting method: Through hole solder termination - exact match required
Connector style: Board-to-board or cable interface - exact match required
Fastening mechanism: Push-pull - exact match required
Shrouding: Unshrouded - exact match required

Variations permitted within substitution scope include contact material composition, contact finish type and thickness, insulation material formulation, overall contact length tolerances, and operating temperature range, provided all other parameters remain constant.

Engineering Selection Recommendations

Amphenol ICC 77313-101-04LF is the primary substitute for the Molex 0879140416. Both parts maintain Active product status, ensuring continued availability and manufacturing support. The 77313-101-04LF carries RoHS Compliant certification and meets the same moisture sensitivity classification. The contact finish differs (gold versus tin), which may provide enhanced corrosion resistance in specific environmental applications. Current inventory for this substitute is 1,542 units.

Amphenol ICC 68692-404H is classified as Obsolete and should not be selected for new designs or long-term production requirements. While this part meets the core mechanical and electrical substitution criteria, its discontinued status creates supply risk and limits future availability. This part is suitable only for legacy system maintenance or repair applications where the original specification must be maintained.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol ICC 77313-101-04LF replace the Molex 0879140416 in existing designs?

A: Yes. Both parts share identical mating pitch (0.100"), position count (4), row configuration (2 rows), contact type (male pin), mounting method (through-hole solder), and fastening mechanism (push-pull). The gold contact finish on the 77313-101-04LF provides an alternative to the tin finish on the original part. Both maintain UL94 V-0 flammability rating and MSL 1 classification.

Q: What is the difference between the contact finishes on these parts?

A: The Molex 0879140416 uses tin contact finish at 100.0µin (2.54µm) thickness. The Amphenol ICC 77313-101-04LF uses gold or gold GXT™ finish at 30.0µin (0.76µm) thickness. Gold finishes typically offer superior corrosion resistance and lower contact resistance over extended service life, particularly in high-humidity or corrosive environments.

Q: Why is the Amphenol ICC 68692-404H listed as Obsolete?

A: The 68692-404H has been discontinued by the manufacturer. While it meets the core substitution parameters, its obsolete status means manufacturing has ceased and inventory is limited. This part should only be used for repair or maintenance of existing systems already using this component.

Q: Are there any differences in contact material between these parts?

A: The Molex 0879140416 uses copper alloy contacts, while both Amphenol ICC substitutes use phosphor bronze. Phosphor bronze provides improved spring characteristics and wear resistance compared to copper alloy, contributing to longer contact life and more reliable mating cycles.

Q: Do all three parts meet RoHS compliance requirements?

A: The Molex 0879140416 is ROHS3 Compliant. Both Amphenol ICC parts are RoHS Compliant. All three parts meet RoHS requirements and are suitable for applications with RoHS mandates.
