Key Parameters

Substitute Part Grouping Explanation

The DF12NB(4.0)-32DP-0.5V(51) qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Number of Positions: 32 (identical)
• Pitch: 0.020" (0.50mm) (identical)
• Number of Rows: 2 (identical)
• Connector Type: Header, Outer Shroud Contacts (identical)
• Mounting Type: Surface Mount (identical)
• Contact Finish: Gold (identical)
• Contact Finish Thickness: 8.00µin (0.203µm) (identical)
• Mated Stacking Height: 4mm (identical)
• Height Above Board: 0.130" (3.30mm) (identical)
• RoHS Status: RoHS Compliant (identical)
• Moisture Sensitivity Level: 1 (Unlimited) (identical)

The substitute part maintains all critical electrical and mechanical parameters required for direct replacement. The primary distinction is product status: the substitute is active production, whereas the main part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The DF12NB(4.0)-32DP-0.5V(51) is the appropriate selection for applications currently specified for the DF12(4.0)-32DP-0.5V(86).

Frequently Asked Questions (FAQ)

Q: Are the DF12(4.0)-32DP-0.5V(86) and DF12NB(4.0)-32DP-0.5V(51) mechanically interchangeable?

A: Yes. Both connectors share identical mounting footprints, pitch spacing (0.50mm), row configuration (2 rows), and height above board (0.130"). PCB layout modifications are not required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are RoHS compliant and carry identical moisture sensitivity level ratings (MSL 1, Unlimited). They satisfy equivalent regulatory requirements for industrial and commercial applications.

Q: What is the significance of the packaging difference?

A: The main part is supplied in bulk packaging, while the substitute is supplied in Tape & Reel format. This reflects standard production practices for active components and does not affect electrical or mechanical performance. Tape & Reel packaging is standard for surface mount components in high-volume manufacturing environments.

Q: Are the contact finishes identical?

A: Yes. Both parts feature gold contact finish with identical thickness specifications (8.00µin / 0.203µm), ensuring equivalent electrical conductivity and corrosion resistance.

Q: Why is the original part classified as obsolete?

A: Product obsolescence reflects manufacturing lifecycle decisions by Hirose Electric Co Ltd. The DF12NB variant represents the current production equivalent, maintaining all functional specifications while ensuring ongoing supply chain availability.
