Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF40C-80DP-0.4V(75) is determined by alignment across the following critical parameters:

Manufacturer Consistency: Both the main part and substitute are manufactured by Hirose Electric Co Ltd, ensuring design compatibility and quality standards.

Connector Series: Both components belong to the DF40 series, maintaining mechanical and electrical compatibility within the product family.

Position Count and Pitch: The substitute maintains the 80-position configuration with 0.4mm (0.016") pitch, ensuring pin-to-pin spacing and contact alignment compatibility.

Mounting Technology: Both components utilize surface mount technology (SMD), allowing direct substitution in PCB assembly processes.

Regulatory Compliance: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications, confirming equivalent trade and export status.

Moisture Sensitivity: Both components carry MSL 1 (Unlimited) rating, indicating no moisture absorption restrictions during storage or handling.

The primary distinction between the main part and substitute lies in connector type orientation and product status, with the substitute offering active availability and enhanced inventory levels.

Engineering Selection Recommendations

For Obsolete Part Replacement: The DF40C-80DP-0.4V(51) serves as the active equivalent for the obsolete DF40C-80DP-0.4V(75). This substitute maintains full mechanical and electrical compatibility through identical position count, pitch, row configuration, and mounting methodology.

For New Designs: The DF40C-80DP-0.4V(51) is the appropriate selection for new applications, as it carries Active product status and RoHS Compliant certification. This ensures long-term availability and compliance with current environmental regulations.

For Legacy System Support: The DF40C-80DP-0.4V(75) remains available in inventory (1138 Pcs) for direct replacement in existing systems where the original part number must be maintained. However, the substitute provides superior long-term supply chain security.

Regulatory Alignment: Both parts share identical ECCN and HTSUS classifications, confirming equivalent export control and tariff treatment. The substitute's RoHS Compliant status provides additional regulatory assurance for applications subject to environmental compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the DF40C-80DP-0.4V(51) directly replace the DF40C-80DP-0.4V(75) in existing assemblies?

A: Yes. Both components share identical position count (80), pitch (0.4mm), row configuration (2), and surface mount technology. The mechanical and electrical interfaces are fully compatible.

Q: What is the significance of the different part number suffixes (75 vs. 51)?

A: The suffix designates specific connector type variants within the DF40 series. The DF40C-80DP-0.4V(51) is a plug configuration with outer shroud contacts, while the DF40C-80DP-0.4V(75) is a receptacle configuration. Both maintain the same core electrical and mechanical specifications for mating applications.

Q: Why is the DF40C-80DP-0.4V(75) listed as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production. However, inventory remains available for legacy system support. For new designs or long-term applications, the active substitute DF40C-80DP-0.4V(51) is recommended.

Q: Are there packaging differences between these parts?

A: The DF40C-80DP-0.4V(75) packaging is not specified in available documentation. The DF40C-80DP-0.4V(51) is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing flexibility for both prototype and production volume requirements.

Q: What is the Moisture Sensitivity Level (MSL) significance for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture absorption restrictions. These components do not require special dry-pack storage or baking procedures prior to assembly, simplifying inventory management and reducing handling complexity.

Q: Does the RoHS Compliant status of the DF40C-80DP-0.4V(51) affect compatibility?

A: No. RoHS compliance indicates the substitute meets environmental restrictions on hazardous substances. This status enhances regulatory alignment for applications subject to environmental compliance requirements and does not impact electrical or mechanical compatibility with the obsolete part.

Q: What are the mated stacking heights available for the substitute part?

A: The DF40C-80DP-0.4V(51) supports mated stacking heights of 1.5mm, 2mm, 2.5mm, 3mm, 3.5mm, and 4mm, providing flexibility for applications requiring specific connector stack configurations.
