Substitute Part Grouping Explanation

The DF40C-50DP-0.4V(51) qualifies as a substitute for the DF40C-50DP-0.4V(68) based on the following critical parameters:

Matching Parameters:

• Manufacturer: Hirose Electric Co Ltd
• Base Product Series: DF40
• Number of Positions: 50
• Pitch: 0.4mm (0.016")
• Mounting Type: Surface Mount
• Moisture Sensitivity Level: 1 (Unlimited)
• ECCN Classification: EAR99
• HTSUS Code: 8536.69.4040

Substitution Basis: The DF40C-50DP-0.4V(51) maintains identical electrical and mechanical specifications within the DF40 connector family. Both parts share the same pitch, position count, and mounting methodology. The primary distinction lies in the connector type designation (receptacle versus plug configuration) and the active product status of the substitute, which ensures ongoing availability and manufacturing support.

Parameter Comparison

Engineering Selection Recommendations

The DF40C-50DP-0.4V(51) is the designated substitute for the obsolete DF40C-50DP-0.4V(68). Selection of the active substitute part is based on the following engineering criteria:

Product Status Alignment: The DF40C-50DP-0.4V(51) maintains active product status with Hirose Electric Co Ltd, ensuring continued manufacturing support, quality assurance, and component availability. The original part's obsolete classification creates supply chain risk and limits access to new inventory.

Compliance and Certification: The substitute part carries ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Both parts share identical ECCN and HTSUS classifications, confirming equivalent trade and export compliance profiles.

Electrical and Mechanical Compatibility: Both connectors operate within the DF40 series framework with identical pitch (0.4mm), position count (50), and surface mount configuration. The MSL rating of 1 (Unlimited) for both parts indicates equivalent moisture handling characteristics suitable for standard manufacturing and storage environments.

Frequently Asked Questions (FAQ)

Q: What is the primary reason for substituting the DF40C-50DP-0.4V(68)?

A: The DF40C-50DP-0.4V(68) is classified as obsolete. The DF40C-50DP-0.4V(51) provides an active alternative within the same DF40 connector family, ensuring continued component availability and manufacturing support.

Q: Are the electrical specifications identical between these two parts?

A: Both parts share identical core electrical specifications: 50 positions, 0.4mm pitch, surface mount configuration, and MSL 1 rating. These parameters define the functional equivalence within the DF40 series.

Q: What is the difference between the DF40C-50DP-0.4V(68) and DF40C-50DP-0.4V(51)?

A: The primary distinction is the connector type designation within the part number suffix. The DF40C-50DP-0.4V(51) is specified as a plug configuration with outer shroud contacts and gold contact finish, while the DF40C-50DP-0.4V(68) is designated as a receptacle. Both maintain the same pitch and position count.

Q: Does the DF40C-50DP-0.4V(51) meet current regulatory requirements?

A: Yes. The DF40C-50DP-0.4V(51) is ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.

Q: What is the packaging format for the substitute part?

A: The DF40C-50DP-0.4V(51) is supplied in Tape & Reel (TR) packaging, standard for surface mount connector components.

Q: Are there any differences in moisture sensitivity between these parts?

A: No. Both the DF40C-50DP-0.4V(68) and DF40C-50DP-0.4V(51) carry an MSL rating of 1 (Unlimited), indicating identical moisture handling and storage requirements.

Q: What is the mated stacking height range for the substitute part?

A: The DF40C-50DP-0.4V(51) supports mated stacking heights of 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm, with a height above board of 0.045" (1.14mm).
