Key Parameters

Substitute Part Grouping Explanation

The DF40C-24DP-0.4V(31) receptacle connector is substitutable with the DF40C-24DP-0.4V(51) based on the following critical parameters:

Matching Parameters:

• Manufacturer: Hirose Electric Co., Ltd.
• Series: DF40
• Number of Positions: 24
• Pitch: 0.4mm (0.016")
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8536.69.4040

The primary distinction between these components is the connector type designation: the DF40C-24DP-0.4V(31) functions as a receptacle, while the DF40C-24DP-0.4V(51) is configured as a plug with outer shroud contacts. Both components share identical electrical and mechanical specifications within the DF40 series architecture, enabling direct functional substitution in mating pair applications.

Parameter Comparison

Engineering Selection Recommendations

The DF40C-24DP-0.4V(51) serves as the active substitute for the obsolete DF40C-24DP-0.4V(31). Selection of the substitute component is supported by the following engineering considerations:

Product Status: The DF40C-24DP-0.4V(31) is classified as obsolete, whereas the DF40C-24DP-0.4V(51) maintains active product status with confirmed inventory availability (1753 units in stock). This status differential ensures continued supply chain access and manufacturing support for the substitute component.

Compliance and Certifications: Both components share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming regulatory equivalence. The DF40C-24DP-0.4V(51) carries explicit RoHS Compliant certification, providing additional environmental compliance documentation for applications requiring such verification.

Electrical and Mechanical Compatibility: Both connectors operate within the DF40 series framework with matching position count (24), pitch specification (0.4mm), and mounting methodology (surface mount). The MSL rating of 1 (Unlimited) is identical across both components, indicating equivalent moisture handling characteristics.

Packaging Consideration: The substitute component is supplied in Tape & Reel (TR) packaging format, which is standard for high-volume surface mount production environments.

Frequently Asked Questions (FAQ)

Q: Can the DF40C-24DP-0.4V(51) directly replace the DF40C-24DP-0.4V(31) in existing designs?

A: The DF40C-24DP-0.4V(51) is electrically and mechanically compatible with the DF40C-24DP-0.4V(31) within the DF40 series connector architecture. Both components share identical position count, pitch, mounting type, and MSL specifications. The primary functional difference is the connector type designation (plug versus receptacle), which is determined by the mating pair requirement in the application circuit.

Q: What is the significance of the different connector type designations between these parts?

A: The DF40C-24DP-0.4V(31) is configured as a receptacle connector, while the DF40C-24DP-0.4V(51) is a plug connector with outer shroud contacts. In a mating pair application, one component functions as the receptacle (female) and the other as the plug (male). Selection between these components depends on the specific role required in the circuit assembly.

Q: Are there any compliance or regulatory differences between these components?

A: Both components share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications. The DF40C-24DP-0.4V(51) carries explicit RoHS Compliant certification, whereas the DF40C-24DP-0.4V(31) does not specify this status. For applications requiring RoHS compliance documentation, the substitute component provides this certification.

Q: What packaging format is used for the substitute component?

A: The DF40C-24DP-0.4V(51) is supplied in Tape & Reel (TR) packaging, which is the standard format for surface mount component production and automated assembly processes.

Q: Why is the DF40C-24DP-0.4V(31) listed as obsolete?

A: The DF40C-24DP-0.4V(31) carries an obsolete product status designation. The DF40C-24DP-0.4V(51) maintains active status with confirmed inventory availability, making it the recommended component for new designs and ongoing production requirements.

Q: Are the electrical specifications identical between these components?

A: Both components operate within the DF40 series with matching position count (24), pitch specification (0.4mm), and moisture sensitivity level (MSL 1 - Unlimited). The substitute component specifies gold contact finish with 2.00µin (0.051µm) thickness and includes solder retention features. These specifications ensure electrical performance equivalence within the connector series.
