DF12(4.0)-36DP-0.5V(86) Equivalent & Substitute Parts

Part Overview

The DF12(4.0)-36DP-0.5V(86) is a 36-position rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount applications with outer shroud contacts and gold plating. This connector is classified as obsolete, making identification of active equivalent parts essential for ongoing production and design continuity. The substitute part DF12NB(4.0)-36DP-0.5V(51) maintains functional compatibility while offering active product status and improved availability.

Substitute Part Grouping Explanation

Substitution of the DF12(4.0)-36DP-0.5V(86) with DF12NB(4.0)-36DP-0.5V(51) is based on the following critical parameters that remain identical between both parts:

• Number of positions: 36
• Pitch: 0.020" (0.50mm)
• Number of rows: 2
• Connector type: Header, Outer Shroud Contacts
• Mounting type: Surface Mount
• Contact finish: Gold
• Contact finish thickness: 8.00µin (0.203µm)
• Mated stacking height: 4mm
• Height above board: 0.130" (3.30mm)
• RoHS compliance: Yes
• Moisture sensitivity level: 1 (Unlimited)

The substitute part belongs to the DF12 series and maintains full electrical and mechanical compatibility. The primary difference is product status: the original part is obsolete, while the substitute is active with higher inventory availability.

Parameter Comparison
