Substitute Part Grouping Explanation

Substitution of the MDF6-10DP-3.5DSA(05) is determined by strict equivalence across the following critical parameters:

• Connector series and family: MDF6
• Number of positions and row configuration: 10 positions in 2 rows
• Mating pitch and row spacing: 0.138" (3.50mm) pitch with 0.197" (5.00mm) row spacing
• Mounting method: Through hole solder termination
• Shrouding configuration: Shrouded 4-wall design
• Contact type and material: Male pin, brass with tin or tin-copper finish
• Electrical ratings: 300V minimum voltage rating
• Temperature range: -30°C to 85°C minimum operating range
• Flammability compliance: UL94 V-0 rating

The substitute part MDF6-10DP-3.5DSA(23) maintains full equivalence across all critical parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The MDF6-10DP-3.5DSA(23) is the direct substitute for the obsolete MDF6-10DP-3.5DSA(05). Both parts maintain identical mechanical and electrical specifications across all critical parameters including connector geometry, pitch, row spacing, mounting configuration, and thermal/voltage ratings.

The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• ROHS3 compliance provides enhanced regulatory alignment compared to RoHS Compliant status
• REACH Unaffected designation confirms compliance with chemical substance regulations
• Significantly higher inventory availability (1177 pcs vs 653 pcs) supports procurement timelines

The contact finish difference (Tin-Copper vs Tin) and contact length mating specification variance (5.60mm vs 5.59mm) fall within acceptable manufacturing tolerances and do not affect functional compatibility or performance in board-to-cable/wire applications.

Frequently Asked Questions (FAQ)

Q: Can MDF6-10DP-3.5DSA(23) be used as a direct replacement for MDF6-10DP-3.5DSA(05)?

A: Yes. Both connectors share identical pitch (3.50mm), row spacing (5.00mm), position count (10 in 2 rows), mounting method (through hole), shrouding design (4-wall), and electrical ratings (300V, -30°C to 85°C). The parts are mechanically and electrically interchangeable.

Q: What is the significance of the contact finish difference between these parts?

A: The original part features Tin-Copper finish while the substitute uses Tin finish. Both finishes provide equivalent corrosion resistance and electrical performance for board-to-cable/wire applications. The finish difference does not affect mating compatibility or signal integrity.

Q: Are there any packaging differences between these parts?

A: The original part has no specified packaging designation, while the substitute is packaged in bags. This difference affects only storage and handling procedures and does not impact connector functionality or performance.

Q: Why is the substitute part recommended despite the obsolete status of the original?

A: The original MDF6-10DP-3.5DSA(05) is obsolete, meaning it is no longer manufactured and inventory is limited. The substitute MDF6-10DP-3.5DSA(23) is an active product with full manufacturing support and significantly higher availability, ensuring long-term supply chain reliability for new designs and ongoing maintenance applications.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts meet UL94 V-0 flammability requirements, EAR99 export classification, and HTSUS 8536.69.4040 tariff codes. The substitute offers enhanced compliance with ROHS3 and REACH Unaffected designations, providing superior regulatory alignment for current applications.
