Substitute Part Grouping Explanation

The substitute part 86840-146HLF is classified as a direct equivalent based on the following critical parameters that determine substitutability:

Connector Type & Series: Both are BERGSTIK® II series headers with identical male pin contact type
Position Configuration: Both feature 46 positions in a 2-row arrangement
Pitch Specifications: Identical mating pitch of 0.100" (2.54mm) and row spacing of 0.100" (2.54mm)
Mounting & Termination: Both are through-hole, right-angle connectors with solder termination and push-pull fastening
Contact Specifications: Identical contact material (Phosphor Bronze), contact shape (Square), contact finish (Gold or Gold, GXT™), and finish thickness (30.0µin / 0.76µm)
Insulation Properties: Identical insulation height (0.190" / 4.83mm), color (Black), and flammability rating (UL94 V-0)
Environmental Rating: Both have MSL 1 (Unlimited) moisture sensitivity level

The primary distinction is that 86840-146HLF is an active product with current availability, whereas 79258-146HLF is obsolete.

Engineering Selection Recommendations

The 86840-146HLF is the direct substitute for the obsolete 79258-146HLF. Both connectors share identical electrical and mechanical specifications across all critical mating and mounting parameters. The substitute part is currently in active production status with documented inventory availability.

The 86840-146HLF provides additional compliance documentation, including RoHS Compliant status and REACH Affected designation, which may be required for new designs or regulatory compliance in certain markets. The substitute also specifies electrical ratings (5A at 110V) not documented for the original part.

A notable dimensional difference exists in the contact post length: the substitute features a longer post (0.230" / 5.84mm) compared to the original (0.120" / 3.05mm). This difference must be evaluated against PCB design specifications and solder joint requirements for the specific application.

Frequently Asked Questions (FAQ)

Q: Can 86840-146HLF be used as a direct replacement for 79258-146HLF in existing designs?

A: Yes, the parts are electrically and mechanically equivalent across all mating and mounting parameters. The longer contact post on the substitute may require PCB design verification to ensure adequate solder joint formation and clearance.

Q: What is the significance of the contact post length difference?

A: The substitute part has a contact post length of 0.230" (5.84mm) versus 0.120" (3.05mm) on the original. This affects solder joint geometry and PCB hole depth requirements. Verify that your PCB design accommodates the longer post length.

Q: Are there any compliance differences between the two parts?

A: The substitute 86840-146HLF is documented as RoHS Compliant and REACH Affected, with specified electrical ratings (5A, 110V). The original part does not have these specifications documented. Both parts meet UL94 V-0 flammability requirements.

Q: What is the packaging difference?

A: The substitute is supplied in Bag packaging, whereas the original part packaging is not specified.

Q: Are both parts from the same manufacturer?

A: Yes, both are manufactured by Amphenol ICC (FCI) and are part of the BERGSTIK® II series.

Q: What is the inventory status of these parts?

A: The original 79258-146HLF is obsolete with 917 pieces in stock. The substitute 86840-146HLF is active with 1105 pieces in stock.
