Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DF20F-20DP-1H(59) is determined by the following critical parameters:

• Connector type, contact type, and series (Header, Male Pin, DF20)
• Position count and row configuration (20 positions, 2 rows)
• Pitch and row spacing (0.039" / 1.00mm)
• Mounting style and orientation (Surface Mount, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Electrical ratings (1A current, 100V voltage)
• Operating temperature range (-35°C ~ 85°C)
• Flammability and compliance standards (UL94 V-0, RoHS)

The DF20F-20DP-1H(52) qualifies as a direct substitute based on matching all critical mechanical and electrical parameters while maintaining compatibility with the same DF20 series platform.

Parameter Comparison

Engineering Selection Recommendations

The DF20F-20DP-1H(52) is the active equivalent for the obsolete DF20F-20DP-1H(59). Both parts maintain identical mechanical and electrical specifications within the DF20 series platform. The primary distinction is product status: the DF20F-20DP-1H(59) is obsolete, while the DF20F-20DP-1H(52) is active and currently in production.

The DF20F-20DP-1H(52) carries ROHS3 compliance, representing current regulatory alignment. Packaging differs between the two parts, with the substitute supplied in Tape & Reel format versus bulk packaging for the original part. Both parts maintain UL94 V-0 flammability rating and unlimited moisture sensitivity level (MSL 1).

For new designs or ongoing procurement, the DF20F-20DP-1H(52) provides continuity of the DF20 connector platform with active manufacturing support and current compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can DF20F-20DP-1H(52) be used as a direct replacement for DF20F-20DP-1H(59)?

A: Yes. Both parts share identical connector type, position count, pitch, mounting configuration, and electrical ratings. The substitute maintains full mechanical and electrical compatibility within the DF20 series.

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

A: The primary difference is product status. The DF20F-20DP-1H(59) is obsolete, while the DF20F-20DP-1H(52) is active. The substitute also features updated ROHS3 compliance and is supplied in Tape & Reel packaging rather than bulk.

Q: Are there any electrical or thermal differences?

A: No. Both parts operate at identical voltage (100V), current (1A), and temperature ranges (-35°C ~ 85°C). Electrical performance and thermal characteristics are equivalent.

Q: Does packaging format affect compatibility?

A: Packaging format does not affect connector compatibility or performance. The DF20F-20DP-1H(52) is supplied in Tape & Reel format, which is standard for surface mount components and may offer advantages in automated assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. The DF20F-20DP-1H(59) is RoHS Compliant, and the DF20F-20DP-1H(52) is ROHS3 Compliant, representing current regulatory standards.
