Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 770875-2 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (6)
• Number of rows (2)
• Mating pitch (0.163" / 4.14mm)
• Row spacing (0.163" / 4.14mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Locking Ramp)
• Insulation height (0.531" / 13.50mm)

Electrical Compatibility Parameters:

• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 105°C)
• Contact material (Brass)
• Insulation material (Polyamide/Nylon)
• Flammability rating (UL94 V-0)

Termination Parameters:

• Solder termination method
• Contact post length (0.175" / 4.45mm)
• Contact post finish thickness (150.0µin / 3.81µm)

The substitute part 1-770875-1 maintains full equivalence across all mechanical, electrical, and termination parameters. Differences exist only in product status and post-contact finish composition, which do not affect functional interchangeability in the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-770875-1 is the direct substitute for the 770875-2 connector header. Both components share identical mechanical, electrical, and termination specifications within the Mini-Universal MATE-N-LOK series.

Product Status Consideration: The 770875-2 carries Last Time Buy status, indicating end-of-life manufacturing. The 1-770875-1 maintains Active product status with higher current inventory availability (3328 pieces versus 2590 pieces), ensuring supply continuity for new production and field service applications.

Compliance Advantage: The 1-770875-1 achieves RoHS Compliance, whereas the 770875-2 is RoHS non-compliant. This distinction becomes significant for applications subject to RoHS regulatory requirements or customer specifications mandating RoHS-compliant components.

Contact Finish Specification: The primary technical difference is the post-contact finish composition. The 770875-2 specifies Tin-Lead finish, while the 1-770875-1 specifies Tin finish.
