Substitute Part Grouping Explanation

Substitution of the DF1EC-8P-2.5DSA(01) is based on strict electrical and mechanical parameter matching within the DF1E series. The substitute part DF1EC-8P-2.5DSA(36) maintains identical specifications across all critical parameters: 8-position configuration, 2.5mm pitch, male pin contact type, through-hole mounting, shrouded 4-wall design, 3A current rating, and -35°C to 85°C operating temperature range. Both parts share the same contact geometry, insulation material (Polyamide/Nylon), gold-plated brass contacts, and UL94 V-0 flammability rating. The primary distinction is product status: the (01) variant is obsolete while the (36) variant is active, with the latter available in bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

The DF1EC-8P-2.5DSA(36) is the direct active equivalent for the obsolete DF1EC-8P-2.5DSA(01). Both parts are electrically and mechanically identical across all specified parameters. The (36) variant offers the advantage of active product status, ensuring continued availability and supply chain support. Additionally, the (36) variant carries RoHS Compliant certification, providing compliance assurance for applications subject to RoHS requirements. For new designs or component replacement in existing applications, the DF1EC-8P-2.5DSA(36) is the appropriate selection.
