Key Parameters

Substitute Part Grouping Explanation

Substitution of the DF17(2.0)-100DP-0.5V(57) is based on the following critical parameters that determine functional compatibility:

Position Count: Both the main part and substitute maintain 100 positions, ensuring equivalent signal routing capacity.

Connector Configuration: Both components feature outer shroud contacts in a 2-row arrangement, maintaining the same physical contact layout.

Mounting Technology: Both are surface mount components, compatible with standard SMD assembly processes.

Contact Material & Finish: Both utilize gold-plated contacts, ensuring equivalent electrical performance and corrosion resistance.

Manufacturer Continuity: Both components are manufactured by Hirose Electric Co Ltd, ensuring design consistency and supply chain alignment.

The substitute part DF40C-100DP-0.4V(51) represents the active production equivalent within the Hirose connector portfolio. While pitch and height specifications differ, these parameters do not prevent functional substitution when the mating connector is also updated to the DF40 series specification.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The DF17(2.0)-100DP-0.5V(57) is classified as obsolete. The DF40C-100DP-0.4V(51) maintains active production status, ensuring long-term availability and supply chain stability for new designs and production continuity.

Compliance & Certification: Both components meet RoHS requirements. The substitute part carries ROHS3 Compliant status and REACH Unaffected designation, providing enhanced regulatory alignment for current manufacturing standards.

Moisture Sensitivity: Both components carry MSL 1 rating (Unlimited), indicating equivalent handling and storage requirements with no moisture sensitivity constraints.

Connector Pairing Requirement: Substitution of the header component requires corresponding substitution of the mating connector to the DF40 series. Direct mechanical mating between DF17 and DF40 series is not possible due to pitch and height differences.

Frequently Asked Questions (FAQ)

Q: Can the DF40C-100DP-0.4V(51) directly replace the DF17(2.0)-100DP-0.5V(57) in existing assemblies?

A: Direct mechanical replacement is not possible. The DF40C features a 0.016" (0.40mm) pitch compared to the DF17's 0.020" (0.50mm) pitch, and a significantly reduced height above board (0.045" vs 0.169"). Substitution requires updating the mating connector to the corresponding DF40 series component.

Q: What is the primary reason for substituting this obsolete connector?

A: The DF17(2.0)-100DP-0.5V(57) is obsolete. The DF40C-100DP-0.4V(51) represents the active production equivalent within Hirose's connector portfolio, ensuring supply availability and manufacturing support for ongoing production requirements.

Q: Are there packaging differences between these components?

A: Yes. The DF17(2.0)-100DP-0.5V(57) packaging is not specified in available documentation. The DF40C-100DP-0.4V(51) is available in Cut Tape (CT) and Digi-Reel® packaging formats, providing standard SMD assembly compatibility.

Q: Do both connectors meet current RoHS requirements?

A: Both components are RoHS compliant. The substitute part carries ROHS3 Compliant designation, representing the current regulatory standard. Both components are unaffected by REACH restrictions.

Q: What are the mated stacking height options for each component?

A: The DF17(2.0)-100DP-0.5V(57) supports mated stacking heights of 5mm and 6mm. The DF40C-100DP-0.4V(51) supports multiple stacking heights: 1.5mm, 2mm, 2.5mm, 3mm, 4.6mm, and 4mm, providing greater flexibility for compact interconnect designs.
