Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DF23C-30DP-0.5V(51) are identified based on the following critical parameters that determine functional compatibility:

Parametric Equivalents maintain identical electrical and mechanical specifications:

• Connector type: Plug, Outer Shroud Contacts
• Number of positions: 30
• Pitch: 0.50mm
• Number of rows: 2
• Mounting type: Surface Mount
• Contact finish: Gold
• Mated stacking height: 1.5mm
• Height above board: 1.20mm

Functional Substitutes share the same series platform and core electrical characteristics but differ in position count or contact configuration:

• Series: DF17 or DF23
• Pitch: 0.50mm
• Mounting type: Surface Mount
• Contact finish: Gold
• Moisture Sensitivity Level: 1 (Unlimited)

The DF23C-30DP-0.5V(92) is a parametric equivalent with identical specifications but active product status and RoHS compliance. The DF17(4.0)-50DS-0.5V(57) is a functional substitute offering higher position density (50 positions) with receptacle configuration, suitable for applications requiring expanded interconnection capacity within the same pitch and mounting platform.

Parameter Comparison

Engineering Selection Recommendations

DF23C-30DP-0.5V(92) is the primary substitute for direct replacement applications. This part maintains identical electrical and mechanical specifications to the obsolete DF23C-30DP-0.5V(51), including connector type, position count, pitch, mounting configuration, and stacking heights. The DF23C-30DP-0.5V(92) carries active product status and RoHS3 compliance, providing long-term availability and regulatory alignment for new designs and production continuity.

DF17(4.0)-50DS-0.5V(57) serves as a functional substitute for applications requiring expanded interconnection capacity. This receptacle connector operates at the same 0.50mm pitch and surface mount platform but provides 50 positions instead of 30, with increased mated stacking heights (6mm, 6.5mm, 8mm) and height above board (4.50mm). Selection of this substitute requires design accommodation for the larger form factor and receptacle configuration. This part is actively manufactured and REACH compliant.

Selection between these substitutes depends on application requirements: use DF23C-30DP-0.5V(92) for direct form-fit-function replacement; use DF17(4.0)-50DS-0.5V(57) only when design modifications to accommodate increased height and position density are feasible.

Frequently Asked Questions (FAQ)

Q: Can DF23C-30DP-0.5V(92) be used as a direct replacement for DF23C-30DP-0.5V(51)?

A: Yes. Both parts share identical specifications for connector type, position count (30), pitch (0.50mm), row configuration (2), mounting type (surface mount), contact finish (gold), and stacking heights. The primary difference is product status: DF23C-30DP-0.5V(51) is obsolete while DF23C-30DP-0.5V(92) is active and RoHS compliant.

Q: What is the key difference between DF23C-30DP-0.5V(92) and DF17(4.0)-50DS-0.5V(57)?

A: The DF23C-30DP-0.5V(92) is a plug connector with 30 positions and 1.5mm mated stacking height. The DF17(4.0)-50DS-0.5V(57) is a receptacle connector with 50 positions and variable mated stacking heights (6mm, 6.5mm, 8mm). Both operate at 0.50mm pitch and surface mount configuration. Selection depends on whether your application requires the plug configuration with 30 positions or can accommodate the receptacle with expanded capacity.

Q: Are packaging differences between DF23C-30DP-0.5V(51) and DF23C-30DP-0.5V(92) significant?

A: The original part DF23C-30DP-0.5V(51) was supplied in standard packaging. The DF23C-30DP-0.5V(92) is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly. This packaging format is compatible with automated pick-and-place equipment used in modern PCB manufacturing.

Q: Can DF17(4.0)-50DS-0.5V(57) be used in applications designed for DF23C-30DP-0.5V(51)?

A: Only if design modifications are implemented. The DF17(4.0)-50DS-0.5V(57) has significantly different physical dimensions: mated stacking heights of 6mm, 6.5mm, or 8mm compared to 1.5mm, and height above board of 4.50mm compared to 1.20mm. Additionally, it is a receptacle rather than a plug. Use this substitute only when your application can accommodate these dimensional changes and requires the additional 20 positions.

Q: What compliance certifications apply to these substitute parts?

A: DF23C-30DP-0.5V(92) is RoHS3 compliant. Both DF23C-30DP-0.5V(92) and DF17(4.0)-50DS-0.5V(57) are REACH unaffected and classified as EAR99 for export control purposes. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.
