Key Parameters

Substitute Part Grouping Explanation

The DF23C-40DP-0.5V(92) qualifies as a parametric equivalent based on the following critical substitution criteria:

• Identical connector series (DF23) and base product number (DF23C)
• Matching position count (40 positions) and row configuration (2 rows)
• Identical pitch specification (0.020" / 0.50mm)
• Identical connector type (Plug, Outer Shroud Contacts)
• Identical mounting technology (Surface Mount)
• Identical contact finish (Gold)
• Identical mated stacking height (1.5mm) and height above board (0.047" / 1.20mm)
• Identical MSL rating (1 - Unlimited)

The primary distinction between these parts is packaging format and product lifecycle status. The DF23C-40DP-0.5V(92) is supplied in Tape & Reel (TR) packaging and maintains active product status, whereas the DF23C-40DP-0.5V(51) is obsolete.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the DF23C-40DP-0.5V(92) be used as a direct replacement for the DF23C-40DP-0.5V(51)?

A: Yes. Both parts are identical in all electrical and mechanical specifications, including position count, pitch, connector type, mounting method, contact finish, and dimensional characteristics. The primary difference is product lifecycle status and packaging format.

Q: What is the significance of the packaging difference between these parts?

A: The DF23C-40DP-0.5V(51) uses unspecified packaging, while the DF23C-40DP-0.5V(92) is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for high-volume surface mount production and is compatible with automated assembly equipment.

Q: Does the DF23C-40DP-0.5V(92) meet current compliance standards?

A: Yes. The DF23C-40DP-0.5V(92) is ROHS3 compliant and carries REACH Unaffected status, meeting current regulatory requirements for electronic components.

Q: Are there any dimensional or electrical differences between these parts?

A: No. Both parts maintain identical mated stacking height (1.5mm), height above board (0.047" / 1.20mm), pitch (0.020" / 0.50mm), and all other specified parameters.

Q: Why is the DF23C-40DP-0.5V(51) classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The DF23C-40DP-0.5V(92) represents the active continuation of this connector family and should be used for all new designs and ongoing production.
