Substitute Part Grouping Explanation

Substitution of the DF23C-18DP-0.5V(73) is determined by the following critical parameters:

• Manufacturer and Series: Both the main part and substitute must be from Hirose Electric Co Ltd, DF23 series
• Number of Positions: Exact match at 18 positions
• Pitch: Exact match at 0.020" (0.50mm)
• Connector Type: Both are plug connectors with outer shroud contacts
• Base Product Number: Both share DF23C as the base product number

The substitute part DF23C-18DP-0.5V(91) meets all these criteria and represents the active production equivalent within the same connector family.

Parameter Comparison

Engineering Selection Recommendations

• Regulatory Compliance: The substitute carries RoHS Compliant certification and standard ECCN classification (EAR99), meeting current environmental and export requirements
• Functional Equivalence: Both parts share identical connector architecture within the DF23 series, with matching position count and pitch specifications
• Packaging Availability: The substitute is available in standard Tape & Reel packaging suitable for automated assembly processes

Frequently Asked Questions (FAQ)

Q: Can DF23C-18DP-0.5V(91) be used as a direct replacement for DF23C-18DP-0.5V(73)?

A: Yes. Both connectors share the same base product number (DF23C), identical position count (18), and pitch specification (0.020" / 0.50mm). The substitute is the active production equivalent within the DF23 rectangular connector family.

Q: What is the significance of the different suffix designations (73 vs. 91)?

A: The suffix designations indicate different production variants or manufacturing dates within the same connector family. The DF23C-18DP-0.5V(91) represents the current active production variant.

Q: Are there any compliance differences between the two parts?

A: The substitute DF23C-18DP-0.5V(91) is RoHS Compliant with MSL rating of 1 (Unlimited), meeting current environmental standards. The obsolete variant carries legacy classification codes.

Q: What packaging options are available for the substitute part?

A: The DF23C-18DP-0.5V(91) is supplied in Tape & Reel (TR) packaging, standard for surface mount connector applications.

Q: Are there any mechanical or electrical differences in connector performance?

A: Both parts maintain identical electrical and mechanical specifications within the DF23 series architecture. The mated stacking height is 1.5mm with a height above board of 0.047" (1.20mm).
