• Contact Type: Male Pin
• Number of Positions: 8
• Number of Rows: 2
• Pitch - Mating: 0.100" (2.54mm)
• Row Spacing - Mating: 0.100" (2.54mm)
• Shrouding: Shrouded - 4 Wall
• Mounting Type: Through Hole
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Shape: Square
• Contact Finish - Mating: Gold
• Contact Finish - Post: Tin
• Contact Material: Copper Alloy
• Material Flammability Rating: UL94 V-0
• Insulation Color: Black
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The 3M part maintains functional and physical compatibility with the Molex original, supporting identical mating and termination requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0878340819 and 3M N2508-6002-RB are Active status products with ROHS3 compliance and REACH Unaffected designation, meeting current regulatory requirements. The 3M N2508-6002-RB provides specified operating temperature range (-55°C ~ 105°C) and current rating (1.75A), whereas the Molex part does not specify these parameters. The 3M substitute features thicker contact finish plating on the post (200.0µin versus 74.8µin), which may provide enhanced durability in high-cycle mating applications. Insulation material differs between the two parts: the Molex uses PBT while the 3M uses PCT with glass filler, both meeting UL94 V-0 flammability requirements. Contact length variations are minor and within typical manufacturing tolerances for this connector class. Selection between these parts should be based on application-specific requirements for operating temperature, current handling, and packaging format (Tray versus Tube).

Frequently Asked Questions (FAQ)

Q: What makes the 3M N2508-6002-RB a valid substitute for the Molex 0878340819?

A: Both connectors share identical core specifications: 8-position, 2-row header with 2.54mm pitch, shrouded 4-wall design, through-hole solder termination, push-pull fastening, square gold-plated mating contacts, and tin-plated posts. Both are ROHS3 compliant with MSL 1 rating and UL94 V-0 flammability certification.

Q: Are there physical differences between these connectors?

A: Minor dimensional variations exist. The 3M part has a slightly longer mating contact (0.243" versus 0.240"), shorter post length (0.112" versus 0.135"), and greater insulation height (0.390" versus 0.365"). These differences are within acceptable tolerances for standard 2.54mm pitch header applications.

Q: What is the difference in insulation material?

A: The Molex uses polybutylene terephthalate (PBT), while the 3M uses polycyclohexylenedimethylene terephthalate (PCT) with glass filler. Both materials meet UL94 V-0 flammability standards and are suitable for the specified applications.

Q: Does the 3M part provide better contact durability?

A: The 3M N2508-6002-RB features thicker tin plating on the post (200.0µin versus 74.8µin), which may offer improved wear resistance in applications requiring frequent mating cycles.

Q: What are the packaging differences?

A: The Molex 0878340819 is supplied in Tray packaging, while the 3M N2508-6002-RB is supplied in Tube packaging. This affects handling and storage but does not impact electrical or mechanical compatibility.

Q: Is the 3M part rated for specific operating temperatures?

A: Yes, the 3M N2508-6002-RB is rated for -55°C to 105°C operation. The Molex part does not specify an operating temperature range in the provided data.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, both connectors are mechanically and electrically compatible for board-to-cable/wire applications with identical mating and termination requirements. PCB footprints and mating connector compatibility remain unchanged.
