Key Parameters

Substitute Part Grouping Explanation

The MDF6-4DP-3.5DSA(23) qualifies as a direct substitute based on the following critical parameters:

• Identical series designation (MDF6)
• Matching connector type (Header) and contact type (Male Pin)
• Identical number of positions (4) and row configuration (2 rows)
• Identical pitch spacing (0.138" / 3.50mm) and row spacing (0.197" / 5.00mm)
• Identical mounting method (Through Hole) and shrouding design (Shrouded - 4 Wall)
• Matching insulation material (Polyamide/Nylon) and color (White)
• Identical voltage rating (300V) and operating temperature range (-30°C ~ 85°C)
• Equivalent flammability rating (UL94 V-0)
• Active product status with improved availability

Minor variations in contact finish specifications and post finish do not affect functional compatibility within the specified electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The MDF6-4DP-3.5DSA(23) is the direct active equivalent for the obsolete MDF6-4DP-3.5DSA(05). Selection of the substitute part is based on:

• Active product status ensuring long-term availability and supply chain continuity
• Identical electrical and mechanical specifications across all critical parameters
• Enhanced compliance certification (ROHS3 vs. RoHS Compliant)
• Improved inventory availability (1020 Pcs vs. 712 Pcs)
• Maintained UL94 V-0 flammability rating and MSL 1 classification
• Equivalent ECCN and HTSUS classifications for regulatory consistency

The contact finish specification change from Tin-Copper to Tin does not affect functional performance within the specified voltage and temperature operating ranges.

Frequently Asked Questions (FAQ)

Q: Are the MDF6-4DP-3.5DSA(05) and MDF6-4DP-3.5DSA(23) mechanically interchangeable?

A: Yes. Both connectors share identical pitch spacing (3.50mm), row spacing (5.00mm), mounting configuration (through-hole), and shrouding design (4-wall). Physical dimensions and board footprints are equivalent.

Q: What is the difference between the contact finish specifications?

A: The MDF6-4DP-3.5DSA(05) features Tin-Copper mating contact finish, while the MDF6-4DP-3.5DSA(23) uses Tin finish. Both meet the 300V voltage rating and UL94 V-0 flammability requirement. The contact finish thickness remains 39.4µin (1.00µm) for mating surfaces in both versions.

Q: Why is the original part marked as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The MDF6-4DP-3.5DSA(23) represents the active continuation within the MDF6 series, maintaining full electrical and mechanical compatibility.

Q: Are there packaging differences between these parts?

A: The MDF6-4DP-3.5DSA(05) packaging is not specified in available data. The MDF6-4DP-3.5DSA(23) is supplied in bag packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts meet current RoHS requirements?

A: The MDF6-4DP-3.5DSA(05) is RoHS Compliant. The MDF6-4DP-3.5DSA(23) meets ROHS3 Compliant status, representing the current regulatory standard. Both parts are REACH Unaffected or equivalent in compliance standing.

Q: What is the current rating for these connectors?

A: The MDF6-4DP-3.5DSA(05) current rating is not specified. The MDF6-4DP-3.5DSA(23) current rating varies by wire gauge. Consult the connector datasheet for specific current capacity based on your wire gauge selection.
