Key Parameters

Substitute Part Grouping Explanation

Substitution for the MDF6-8DP-3.5DSA(05) is determined by strict equivalence across the following critical parameters:

• Connector type (Header)
• Number of positions (8) and row configuration (2 rows)
• Mating pitch (0.138" / 3.50mm) and row spacing (0.197" / 5.00mm)
• Mounting method (Through Hole)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Latch Holder)
• Voltage rating (300V)
• Operating temperature range (-30°C ~ 85°C)
• Material flammability compliance (UL94 V-0)

The substitute part MDF6-8DP-3.5DSA(23) maintains all these critical parameters while offering active product status and updated compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The MDF6-8DP-3.5DSA(23) is the direct active equivalent for the obsolete MDF6-8DP-3.5DSA(05). Both parts maintain identical mechanical and electrical specifications across all critical connector parameters. The substitute part offers the following advantages:

• Active product status ensures ongoing availability and manufacturing support
• ROHS3 compliance provides updated regulatory alignment compared to the original RoHS Compliant designation
• REACH Unaffected status confirms compliance with current chemical substance regulations
• Identical contact geometry, pitch, and row spacing ensure direct PCB compatibility
• Equivalent voltage rating (300VAC/DC) and operating temperature range (-30°C ~ 85°C) maintain electrical performance

The minor variation in contact finish mating surface (Tin versus Tin-Copper) and contact finish post thickness specification does not affect functional compatibility or performance in standard applications.

Frequently Asked Questions (FAQ)

Q: Can MDF6-8DP-3.5DSA(23) be used as a direct replacement for MDF6-8DP-3.5DSA(05)?

A: Yes. Both parts share identical connector type, position count, pitch, row spacing, mounting method, shrouding design, termination, and fastening specifications. PCB footprints and mating interface dimensions are equivalent.

Q: What is the difference between the contact finishes?

A: The original part specifies Tin-Copper contact finish on the mating surface, while the substitute specifies Tin. Both finishes provide equivalent electrical conductivity and corrosion resistance for standard applications within the specified voltage and temperature ranges.

Q: Are there packaging differences between these parts?

A: The MDF6-8DP-3.5DSA(05) is supplied without specified packaging, while MDF6-8DP-3.5DSA(23) is supplied in Bag packaging. This affects logistics and storage but does not alter component functionality or performance.

Q: Why is the original part obsolete?

A: The MDF6-8DP-3.5DSA(05) has been discontinued by the manufacturer. The MDF6-8DP-3.5DSA(23) represents the current active production equivalent within the MDF6 series.

Q: Are the voltage ratings identical?

A: Both parts are rated for 300V. The substitute specifies 300VAC/DC, providing explicit confirmation of both AC and DC voltage capability, while the original specification lists 300V without this distinction.

Q: What is the MSL rating for these connectors?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity limitations during storage or handling.
