DF12B(3.0)-40DP-0.5V(86) Equivalent & Substitute Parts

Part Overview

The DF12B(3.0)-40DP-0.5V(86) is a 40-position rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount applications with outer shroud contacts and gold plating. This part is classified as obsolete, making identification of equivalent and substitute components essential for ongoing production support, design updates, and inventory management. Active alternatives within the DF12 series and cross-manufacturer options provide functional equivalence while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF12B(3.0)-40DP-0.5V(86) is determined by strict alignment of the following critical parameters:

• Connector Type: Header with outer shroud contacts (mechanical and electrical interface requirement)
• Position Count: 40 positions (signal routing and PCB footprint compatibility)
• Pitch: 0.020" (0.50mm) (contact spacing and mating interface standard)
• Row Configuration: 2 rows (physical layout and contact arrangement)
• Mounting Method: Surface mount (assembly process and PCB integration)
• Contact Finish: Gold (electrical performance and corrosion resistance)
• Stacking Height: 3mm mated height (mechanical clearance and connector stack compatibility)
• RoHS Compliance: RoHS3 or equivalent (regulatory and supply chain requirement)
• Moisture Sensitivity: MSL 1 (storage and handling compatibility)

Two substitute parts meet these criteria: DF12NB(3.0)-40DP-0.5V(51) from Hirose Electric Co Ltd (same manufacturer, active product status) and AXK640347YG from Panasonic Electric Works (cross-manufacturer equivalent, active product status).

Parameter Comparison

Engineering Selection Recommendations

DF12NB(3.0)-40DP-0.5V(51) is the primary substitute for the obsolete DF12B(3.0)-40DP-0.5V(86). Both parts are manufactured by Hirose Electric Co Ltd within the DF12 series, ensuring design continuity and supply chain alignment. The DF12NB variant is active in production with ROHS3 compliance and REACH unaffected status, providing regulatory assurance for new designs and ongoing production. Inventory availability of 939 units supports near-term procurement requirements.

AXK640347YG from Panasonic Electric Works serves as a cross-manufacturer equivalent when Hirose supply is constrained. This part maintains all critical electrical and mechanical parameters, including 40-position configuration, 0.50mm pitch, 2-row layout, surface mount assembly, gold contact finish, and 3mm stacking height. ROHS3 compliance and REACH unaffected status align with current regulatory requirements. Significantly higher inventory availability (90200 units) provides supply security for high-volume applications. The height above board specification of 0.094" (2.40mm) represents a 0.003" (0.10mm) variance from the original part; this minor difference is within typical PCB design tolerances for connector applications.

Frequently Asked Questions (FAQ)

Q: Can DF12NB(3.0)-40DP-0.5V(51) be used as a direct replacement for DF12B(3.0)-40DP-0.5V(86)?

A: Yes. Both parts share identical electrical and mechanical specifications: 40-position header configuration, 0.50mm pitch, 2-row layout, surface mount assembly, gold contact finish, 3mm stacking height, and MSL 1 moisture sensitivity. The DF12NB variant is the active production equivalent within the Hirose DF12 series.

Q: What is the significance of the height above board difference between DF12B and AXK640347YG?

A: The AXK640347YG specifies 0.094" (2.40mm) height above board compared to 0.091" (2.30mm) for the DF12B. This 0.003" (0.10mm) difference is within standard PCB design tolerances for connector clearance and does not affect electrical performance or mating interface compatibility.

Q: Are both substitute parts RoHS compliant?

A: Yes. DF12NB(3.0)-40DP-0.5V(51) and AXK640347YG both carry ROHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing and supply.

Q: Which substitute part should be selected for maximum inventory availability?

A: AXK640347YG from Panasonic Electric Works provides the highest inventory availability at 90200 units, compared to 939 units for DF12NB(3.0)-40DP-0.5V(51). Selection depends on supply chain strategy and design continuity requirements.

Q: Are there packaging differences between the substitute parts?

A: DF12NB(3.0)-40DP-0.5V(51) is supplied in Tape & Reel (TR) packaging. AXK640347YG is supplied in Cut Tape (CT) and Digi-Reel® packaging. Packaging selection should align with assembly process requirements and inventory management procedures.

Q: Do both substitute parts support solder retention?

A: DF12NB(3.0)-40DP-0.5V(51) explicitly specifies solder retention features. AXK640347YG does not specify this feature in the provided data. Verification of solder retention capability for the Panasonic part is recommended during design validation if this feature is critical to the application.
