DF23C-10DP-0.5V(73) Equivalent & Substitute Parts

Part Overview

The DF23C-10DP-0.5V(73) is a 10-position rectangular connector plug manufactured by Hirose Electric Co Ltd. This component is classified as obsolete and is no longer in active production. Due to its obsolete status, sourcing original units becomes increasingly difficult. The DF23C-10DP-0.5V(91) serves as the direct manufacturer-recommended substitute, offering equivalent electrical and mechanical functionality with the advantage of active production status and significantly higher inventory availability.

Key Parameters

Substitute Part Grouping Explanation

The DF23C-10DP-0.5V(91) is designated as the manufacturer-recommended substitute for DF23C-10DP-0.5V(73). Substitution eligibility is determined by the following critical parameters:

• Base product number match (DF23C series)
• Connector type and position count (10-position plug)
• Contact pitch (0.50mm / 0.020")
• Electrical and mechanical interface compatibility
• Manufacturer designation as approved substitute

The primary distinction between these parts is packaging format and product lifecycle status. The substitute maintains full functional equivalence while offering active production status and improved supply chain availability.

Parameter Comparison

Engineering Selection Recommendations

Selection between the original part and its substitute should be based on the following criteria:

DF23C-10DP-0.5V(73) - Original Part:

• Use only when existing inventory is available and project timeline permits sourcing
• Obsolete status limits future availability and supply chain reliability
• No active production support from manufacturer

DF23C-10DP-0.5V(91) - Recommended Substitute:

• Active production status ensures long-term availability and supply chain continuity
• ROHS3 compliance and REACH unaffected status meet current regulatory requirements
• Moisture Sensitivity Level 1 (Unlimited) provides superior handling flexibility
• Significantly higher inventory levels reduce procurement lead times
• Tape & Reel packaging supports automated assembly processes
• Manufacturer-designated substitute ensures functional and mechanical equivalence

For new designs or production runs, the DF23C-10DP-0.5V(91) is the appropriate selection. For legacy system maintenance where original part specifications are critical, the DF23C-10DP-0.5V(73) may be sourced from existing inventory while supplies remain available.

Frequently Asked Questions (FAQ)

Q: Are DF23C-10DP-0.5V(73) and DF23C-10DP-0.5V(91) electrically equivalent?

A: Yes. Both parts share the same base product number (DF23C), connector type, position count (10), and contact pitch (0.50mm), ensuring electrical equivalence for mating and signal integrity.

Q: What is the significance of the different part number suffixes (73 vs 91)?

A: The suffix designates the packaging and production variant. The (73) variant is obsolete, while the (91) variant is in active production with Tape & Reel packaging suitable for automated assembly.

Q: Can DF23C-10DP-0.5V(91) be used as a direct replacement in existing assemblies?

A: Yes. The substitute maintains identical electrical and mechanical interfaces. Surface mount mounting type and gold contact finish are standard specifications for this connector series.

Q: What are the compliance advantages of the substitute part?

A: DF23C-10DP-0.5V(91) is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original part's obsolete status limits compliance documentation availability.

Q: How does packaging affect component selection?

A: DF23C-10DP-0.5V(91) is supplied in Tape & Reel format, optimized for high-volume automated assembly. This packaging format reduces handling costs and improves production efficiency compared to alternative packaging methods.

Q: Is the Moisture Sensitivity Level difference significant?

A: DF23C-10DP-0.5V(91) has MSL 1 (Unlimited), meaning no moisture precautions are required during storage and handling. This simplifies logistics and reduces component damage risk during supply chain operations.
