Substitute Part Grouping Explanation

Substitution eligibility for the DF20F-20DP-1V(56) is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type: Header
• Contact type: Male Pin
• Number of positions: 20
• Number of rows: 2
• Pitch - mating: 0.039" (1.00mm)
• Row spacing - mating: 0.039" (1.00mm)
• Mounting type: Surface Mount
• Shrouding: Shrouded - 4 Wall
• Termination: Solder
• Fastening type: Push-Pull
• Insulation height: 0.181" (4.60mm)
• Contact shape: Square
• Contact finish - mating: Gold
• Contact material: Phosphor Bronze
• Insulation material: Polyamide (PA), Nylon
• Operating temperature range: -35°C ~ 85°C
• Voltage rating: 100V
• Mated stacking height: 5.8mm
• Material flammability rating: UL94 V-0
• Moisture sensitivity level: 1 (Unlimited)

The DF20EF-20DP-1V(52) qualifies as a direct substitute based on full alignment with all mandatory parameters. The primary distinction is product status: the substitute is active and available in higher inventory quantities with improved packaging (Tape & Reel format).

Parameter Comparison

Engineering Selection Recommendations

The DF20EF-20DP-1V(52) is the direct substitute for the obsolete DF20F-20DP-1V(56). Both components are manufactured by Hirose Electric Co Ltd within the DF20 series and maintain identical electrical and mechanical specifications across all critical parameters.

Compliance Status: The substitute part carries ROHS3 compliance, which supersedes the RoHS compliance of the original part, ensuring alignment with current regulatory requirements. Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Availability Advantage: The substitute is currently in active production status with significantly higher inventory availability (30,400 units versus 2,100 units), reducing supply chain risk for new designs and production runs.

Packaging Consideration: The substitute is supplied in Tape & Reel format, which is standard for automated assembly processes and provides cost efficiency for high-volume manufacturing operations.

Frequently Asked Questions (FAQ)

Q: Are the DF20F-20DP-1V(56) and DF20EF-20DP-1V(52) mechanically interchangeable?

A: Yes. Both connectors share identical mechanical dimensions, including pitch (1.00mm), row spacing (1.00mm), insulation height (4.60mm), and mated stacking height (5.8mm). They are fully interchangeable in board-level applications.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging. The DF20F-20DP-1V(56) is obsolete with limited inventory, while the DF20EF-20DP-1V(52) is active production with Tape & Reel packaging. All electrical and mechanical specifications are identical.

Q: Can I use the substitute in existing designs without modification?

A: Yes. The substitute maintains all critical electrical parameters: 1A current rating, 100V voltage rating, -35°C to 85°C operating temperature range, and identical contact materials and finishes. No design modifications are required.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The DF20EF-20DP-1V(52) carries ROHS3 compliance, which is the current regulatory standard. Both parts maintain UL94 V-0 flammability rating and MSL 1 moisture sensitivity classification.

Q: What is the advantage of Tape & Reel packaging?

A: Tape & Reel format is optimized for automated pick-and-place assembly processes, reducing manual handling and improving production efficiency for high-volume manufacturing.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts maintain identical electrical specifications: 1A current rating, 100V voltage rating, gold-plated phosphor bronze contacts, and identical operating temperature range (-35°C to 85°C).
