Substitute Part Grouping Explanation

Substitution of the 68046-628 is determined by strict equivalence across the following critical parameters:

Connector type (Receptacle) and contact type (Female Socket)
Position count (56 positions) and row configuration (2 rows)
Mating pitch (0.100" / 2.54mm) and row spacing (0.100" / 2.54mm)
Mounting method (Surface Mount) and termination type (Solder)
Fastening mechanism (Push-Pull)
Contact finish specification (Gold or Gold, GXT™)
Operating temperature range (-65°C ~ 125°C)
Voltage rating (1000V)
Insulation material (Polyphenylene Sulfide, Glass Filled)
Flammability rating (UL94 V-0)

The substitute part 68046-628LF maintains identical electrical and mechanical specifications while differing in product status and RoHS compliance.

Engineering Selection Recommendations

The 68046-628LF serves as the direct functional equivalent to the obsolete 68046-628. Both parts share identical electrical and mechanical specifications across all critical parameters including connector geometry, contact configuration, termination method, and environmental ratings.

The primary distinction between these parts is product status and regulatory compliance. The 68046-628LF is an active product with RoHS compliance, whereas the 68046-628 is obsolete and RoHS non-compliant. For new designs or system updates, the 68046-628LF is the appropriate selection. For legacy system maintenance requiring exact part matching, the 68046-628 remains functionally equivalent where supply permits.

Both parts carry identical ECCN and HTSUS classifications and share the same base product number (68046), confirming their interchangeability within the Dubox™ series.

Frequently Asked Questions (FAQ)

Q: Can the 68046-628LF be used as a direct replacement for the 68046-628?

A: Yes. The 68046-628LF is electrically and mechanically equivalent to the 68046-628.
