Substitute Part Grouping Explanation

Substitution for the DF20F-10DP-1H(90) is determined by strict equivalence across the following critical parameters:

Connector type, contact type, and series (Header, Male Pin, DF20)
Position count and row configuration (10 positions, 2 rows)
Pitch and row spacing (0.039" / 1.00mm)
Mounting style and orientation (Surface Mount, Right Angle)
Shrouding design (Shrouded - 4 Wall)
Termination method (Solder)
Contact material and finish specifications (Phosphor Bronze, Gold plating)
Insulation material (Polyamide/Nylon)
Electrical ratings (100VAC, -35°C ~ 85°C)
Compliance certifications (RoHS, UL94 V-0)

The identified substitute maintains all these parameters while transitioning from obsolete to active product status, ensuring functional and mechanical compatibility without design modification.

Engineering Selection Recommendations

The DF20F-10DP-1H(91) is the direct equivalent substitute for the obsolete DF20F-10DP-1H(90). Both components are manufactured by Hirose Electric Co Ltd within the DF20 series and maintain identical electrical, mechanical, and material specifications. The primary distinction is product status: the DF20F-10DP-1H(90) is obsolete, while the DF20F-10DP-1H(91) is active and currently available in production quantities.

Both parts satisfy RoHS compliance requirements and UL94 V-0 flammability certification. The MSL rating of 1 (Unlimited) applies to both variants, indicating no moisture sensitivity constraints during storage or handling. The DF20F-10DP-1H(91) is supplied in Tape & Reel packaging, which is standard for high-volume surface mount assembly operations.

For new designs or production continuity, the DF20F-10DP-1H(91) is the appropriate selection. For existing assemblies using the DF20F-10DP-1H(90), direct substitution with the DF20F-10DP-1H(91) is functionally and mechanically equivalent without requiring PCB or assembly process modifications.

Frequently Asked Questions (FAQ)

Q: Are the DF20F-10DP-1H(90) and DF20F-10DP-1H(91) mechanically interchangeable?

A: Yes. Both components share identical mechanical dimensions, pitch specifications (0.039" / 1.00mm), row spacing, shrouding design, and mounting orientation (surface mount, right angle). PCB footprints and assembly processes require no modification.

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

A: The DF20F-10DP-1H(90) is classified as obsolete, while the DF20F-10DP-1H(91) is active. All electrical, mechanical, and material specifications are identical. The packaging differs: the DF20F-10DP-1H(91) is supplied in Tape & Reel format.

Q: Can I use the DF20F-10DP-1H(91) as a direct replacement in existing designs?

A: Yes. The DF20F-10DP-1H(91) is a direct substitute with no design modifications required. Electrical ratings, operating temperature range, voltage specifications, and contact configurations are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both the DF20F-10DP-1H(90) and DF20F-10DP-1H(91) are RoHS compliant and carry UL94 V-0 flammability certification.

Q: What is the MSL rating for these connectors?

A: Both parts have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints. Standard storage and handling practices are sufficient.

Q: Why is the DF20F-10DP-1H(90) obsolete?

A: Product obsolescence is determined by the manufacturer. The DF20F-10DP-1H(91) is the active equivalent and is the recommended selection for all applications.
