DF20F-10DP-1H(59) Equivalent & Substitute Parts

Part Overview

The DF20F-10DP-1H(59) is a rectangular connector header manufactured by Hirose Electric Co Ltd, designed for surface mount, right-angle applications with 10 positions at 1.00mm pitch. This connector is classified as obsolete, which necessitates identification of active equivalent parts to maintain design continuity and ensure long-term component availability for new production runs and field replacements.

Substitute Part Grouping Explanation

Substitution of the DF20F-10DP-1H(59) is determined by strict equivalence across the following critical parameters:

• Connector series: DF20
• Number of positions: 10
• Number of rows: 2
• Pitch - mating: 0.039" (1.00mm)
• Row spacing - mating: 0.039" (1.00mm)
• Connector type: Header
• Contact type: Male Pin
• Mounting type: Surface Mount, Right Angle
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Push-Pull
• Operating temperature range: -35°C ~ 85°C
• Voltage rating: 100V
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The DF20F-10DP-1H(52) meets all these criteria and is classified as an active product, making it a direct functional equivalent for the obsolete DF20F-10DP-1H(59).

Parameter Comparison

Engineering Selection Recommendations

The DF20F-10DP-1H(52) is the direct substitute for the obsolete DF20F-10DP-1H(59). Both parts maintain identical mechanical and electrical specifications across all critical parameters including pitch, position count, mounting configuration, and operating range.

The DF20F-10DP-1H(52) carries active product status, ensuring ongoing availability and manufacturing support. It meets ROHS3 compliance, which supersedes the RoHS compliance of the original part, providing enhanced regulatory alignment for current production environments. The contact finish differs between the two parts—the original uses tin plating while the substitute uses gold plating—both of which are acceptable for the specified 100V/1A application within the DF20 series design envelope.

Frequently Asked Questions (FAQ)

Q: Can the DF20F-10DP-1H(52) be used as a direct replacement for DF20F-10DP-1H(59)?

A: Yes. Both parts share identical mechanical dimensions, electrical ratings, and functional specifications. The DF20F-10DP-1H(52) is the active equivalent and is suitable for direct substitution in new designs and field replacements.

Q: What is the difference between the tin and gold contact finishes?

A: The original DF20F-10DP-1H(59) uses tin plating on mating and post contacts. The substitute DF20F-10DP-1H(52) uses gold plating. Both finishes are compatible with the 100V/1A electrical specification and the DF20 series connector design. Gold plating provides enhanced corrosion resistance and contact reliability in demanding environments.

Q: Are there any dimensional differences between these parts?

A: Insulation height measurements are nominally equivalent: 0.217" (5.51mm) for the original and 0.217" (5.50mm) for the substitute. This 0.01mm variance is within standard manufacturing tolerance and does not affect mechanical or electrical compatibility.

Q: Does the ROHS3 compliance of the substitute affect compatibility?

A: No. ROHS3 compliance is a regulatory enhancement that supersedes RoHS compliance. The DF20F-10DP-1H(52) meets all material restrictions required for current production standards while maintaining full electrical and mechanical compatibility with the original part.

Q: What is the packaging format for the substitute part?

A: The DF20F-10DP-1H(52) is supplied in Tape & Reel (TR) format, consistent with the original part's packaging specification for automated assembly processes.
