Key Parameters

Substitute Part Grouping Explanation

Substitution of the MDF6-4DP-3.5DS(05) is determined by the following critical parameters that must remain constant:

• Connector Series: MDF6 (ensures mechanical and electrical compatibility)
• Number of Positions: 4 positions in 2 rows
• Pitch Spacing: 0.138" (3.50mm) mating pitch and 0.197" (5.00mm) row spacing
• Mounting Configuration: Through hole, right-angle orientation
• Shrouding Design: Shrouded with 4-wall protection
• Contact Type: Male pin with square contact shape
• Termination Method: Solder termination with latch holder fastening
• Voltage Rating: 300V minimum
• Flammability Rating: UL94 V-0
• Insulation Material: Polyamide (PA), Nylon

The substitute part MDF6-4DP-3.5DS(23) maintains all critical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The MDF6-4DP-3.5DS(23) is the direct active equivalent for the obsolete MDF6-4DP-3.5DS(05). Both parts maintain identical mechanical and electrical specifications within the MDF6 series, ensuring pin-for-pin compatibility in existing designs.

The substitute part offers the following advantages:

• Active Product Status: MDF6-4DP-3.5DS(23) is actively manufactured and supported by Hirose Electric Co Ltd, ensuring long-term availability and supply chain stability.
• Enhanced Compliance: ROHS3 compliance provides alignment with current regulatory requirements, compared to the RoHS Compliant status of the original part.
• Improved Availability: Current inventory of 1,021 pieces supports immediate procurement needs.
• Consistent Certifications: Both parts maintain UL94 V-0 flammability rating, MSL 1 moisture sensitivity, and EAR99 export classification.

The minor variation in contact finish mating surface (Tin-Copper versus Tin) and operating temperature lower limit (-30°C versus -35°C) do not affect functional compatibility for standard applications within the specified voltage and temperature operating ranges.

Frequently Asked Questions (FAQ)

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

A: Yes. Both connectors maintain identical pitch spacing (0.138" / 3.50mm), row spacing (0.197" / 5.00mm), mounting configuration (through-hole right-angle), and shrouding design (4-wall). They are direct mechanical substitutes.

Q: What is the difference between the contact finishes?

A: The original part features Tin-Copper contact finish on mating surfaces, while the substitute uses Tin finish. Both maintain 39.4µin (1.00µm) thickness and are suitable for the 300V rating. The Tin finish in the substitute part is standard for this connector series.

Q: Does the operating temperature range difference affect compatibility?

A: The substitute part operates from -30°C to 85°C, compared to -35°C to 85°C for the original. For applications requiring operation below -30°C, the original specification must be maintained. For standard industrial applications within -30°C to 85°C, the substitute is fully compatible.

Q: What packaging is provided with the substitute part?

A: The MDF6-4DP-3.5DS(23) is supplied in bag packaging, compared to unspecified packaging for the obsolete part. This does not affect connector functionality or performance.

Q: Are both parts RoHS compliant?

A: Yes. The original part is RoHS Compliant, and the substitute is ROHS3 Compliant. Both meet lead-free and hazardous substance restrictions. ROHS3 represents the current regulatory standard.

Q: Can I use the substitute part in existing PCB designs without modification?

A: Yes. The substitute maintains all critical mechanical and electrical parameters: 4-position configuration, 3.50mm pitch, 5.00mm row spacing, through-hole right-angle mounting, and 300V voltage rating. No PCB layout or design changes are required.
