Engineering Selection Recommendations

The DF20F-20DP-1H(91) is the direct substitute for the obsolete DF20F-20DP-1H(90). Both components are manufactured by Hirose Electric Co Ltd and maintain identical electrical and mechanical specifications across all critical parameters including connector type, position count, pitch, mounting configuration, and environmental ratings.

The primary distinction between these parts is product status and packaging format. The DF20F-20DP-1H(90) is classified as obsolete, while the DF20F-20DP-1H(91) maintains active production status. The substitute part is supplied in Tape & Reel (TR) packaging, which is standard for high-volume manufacturing and automated assembly processes.

Both components carry RoHS compliance certification and identical MSL ratings, confirming compatibility for applications requiring regulatory adherence and controlled moisture exposure handling. The active status of the DF20F-20DP-1H(91) ensures ongoing availability and supply chain continuity for new designs and legacy system support.

Frequently Asked Questions (FAQ)

Q: Are the DF20F-20DP-1H(90) and DF20F-20DP-1H(91) electrically and mechanically interchangeable?

A: Yes. Both components share identical specifications for connector type, position count, pitch, mounting orientation, shrouding design, termination method, and contact materials. They are direct functional equivalents.

Q: What is the significance of the different packaging formats?

A: The DF20F-20DP-1H(90) uses standard packaging, while the DF20F-20DP-1H(91) is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly and high-volume production. Component selection should align with manufacturing process requirements and assembly equipment capabilities.

Q: Why is the DF20F-20DP-1H(90) classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this specific part number variant. The DF20F-20DP-1H(91) represents the current production equivalent and should be specified for new designs and ongoing procurement.

Q: Are there any compliance or certification differences between these parts?

A: No. Both components carry identical RoHS compliance status, UL94 V-0 flammability rating, and MSL classification. Environmental and regulatory specifications are equivalent.

Q: What inventory considerations apply to these parts?

A: The DF20F-20DP-1H(90) has limited inventory availability due to obsolete status. The DF20F-20DP-1H(91) maintains active production with standard supply chain availability. For new procurement, the active part number is recommended to ensure supply continuity.
