Substitute Part Grouping Explanation

Substitution of the DF5A-4DP-5DSA(05) is determined by strict equivalence across the following critical parameters:

Connector type, contact type, and mating interface (Header, Male Pin)
Position count and row configuration (4 positions, 2 rows)
Pitch specifications (0.197" / 5.00mm mating pitch and row spacing)
Mounting method (Through Hole)
Shrouding design (Shrouded - 4 Wall)
Fastening mechanism (Locking Ramp)
Contact geometry and material (Square, Brass with Tin finish)
Insulation specifications (Polyamide/Nylon, UL94 V-0)
Thermal operating range (-35°C ~ 85°C)
Mated stacking height (22.5mm)

The substitute part DF5A-4DP-5DSA(35) maintains identical electrical and mechanical specifications across all these parameters, differing only in packaging configuration and product status.

Engineering Selection Recommendations

The DF5A-4DP-5DSA(35) is a direct functional equivalent to the DF5A-4DP-5DSA(05). Both parts are manufactured by Hirose Electric Co Ltd within the DF5 series and maintain identical electrical and mechanical specifications.

The primary distinction is product status: the DF5A-4DP-5DSA(05) is obsolete, while the DF5A-4DP-5DSA(35) maintains active status. The substitute part is supplied in bulk packaging and carries RoHS compliance certification, providing additional regulatory alignment for modern applications.

All critical parameters—connector geometry, contact configuration, pitch spacing, mounting method, fastening mechanism, material composition, thermal range, and flammability rating—are identical between the two parts. Selection of the DF5A-4DP-5DSA(35) eliminates obsolescence risk while maintaining full compatibility with existing board designs and mating connectors.

Frequently Asked Questions (FAQ)

Q: Are the DF5A-4DP-5DSA(05) and DF5A-4DP-5DSA(35) mechanically interchangeable?

A: Yes. Both parts share identical mechanical specifications including pitch (5.00mm), position count (4), row configuration (2 rows), shrouding design (4 Wall), fastening type (Locking Ramp), and all contact dimensions. They are fully interchangeable in board-level applications.

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

A: The primary differences are product status and packaging. The DF5A-4DP-5DSA(05) is obsolete, while the DF5A-4DP-5DSA(35) is active. The substitute part is supplied in bulk packaging and includes RoHS compliance certification. All electrical and mechanical specifications are identical.

Q: Can I use the DF5A-4DP-5DSA(35) as a direct replacement in existing designs?

A: Yes. The substitute part maintains full compatibility with existing PCB layouts, mating connectors, and system requirements. No design modifications are necessary.

Q: Are there any thermal or environmental differences between these parts?

A: No. Both parts operate across the identical temperature range (-35°C ~ 85°C), maintain the same moisture sensitivity level (MSL 1 - Unlimited), and carry the same flammability rating (UL94 V-0).

Q: What is the significance of the packaging difference?

A: The DF5A-4DP-5DSA(05) packaging is not specified in available data, while the DF5A-4DP-5DSA(35) is supplied in bulk packaging. This affects procurement and handling but does not impact component performance or compatibility.

Q: Does the RoHS compliance of the DF5A-4DP-5DSA(35) affect compatibility?

A: No. RoHS compliance is an additional regulatory certification that does not alter the electrical or mechanical function of the component. It ensures the part meets environmental standards for hazardous substance restrictions.
