Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 770874-2 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

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

Electrical Compatibility Parameters:

• Contact finish at mating surface (Gold)
• Operating temperature range (-20°C ~ 105°C)
• Voltage rating (600VAC)
• Material flammability rating (UL94 V-0)

Series Designation:

• Mini-Universal MATE-N-LOK series

Substitute parts must maintain identical specifications across all listed parameters. Variations in post-side contact finish (Tin-Lead versus Tin) do not preclude substitution, as this parameter does not affect mating interface compatibility or electrical performance in the application circuit.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-770874-1 is a direct functional equivalent to the 770874-2 across all critical mechanical and electrical parameters. Both components share identical connector architecture, pitch spacing, shrouding configuration, and electrical ratings within the Mini-Universal MATE-N-LOK series.

Product Status Consideration: The 770874-2 carries Last Time Buy status, indicating end-of-life production. The 1-770874-1 maintains Active product status, ensuring continued availability and supply chain stability for new procurement and design continuity.

Compliance Advantage: The 1-770874-1 achieves ROHS3 compliance, whereas the 770874-2 is RoHS non-compliant. For applications subject to RoHS regulatory requirements or customer specifications mandating RoHS compliance, the 1-770874-1 provides superior regulatory alignment.

Contact Finish Variation: The post-side contact finish differs between parts (Tin-Lead on 770874-2 versus Tin on 1-770874-1). This variation does not affect mating interface performance or electrical circuit operation, as the mating surface finish remains identical (Gold, 30.0µin thickness) on both components.

Selection of the 1-770874-1 is appropriate for all applications currently specified for the 770874-2, with the added benefit of active product status and improved regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the 1-770874-1 be used as a direct replacement for the 770874-2 in existing designs?

A: Yes. The 1-770874-1 is mechanically and electrically equivalent to the 770874-2 across all critical parameters. Both components feature identical 4-position, 2-row configuration with 0.163" (4.14mm) pitch spacing, shrouded 4-wall design, through-hole solder termination, and locking ramp fastening. Mating interface specifications, operating temperature range, and voltage ratings are identical.

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

A: The mating surface finish is identical on both parts (Gold, 30.0µin thickness). The difference exists only on the post-side termination finish: the 770874-2 uses Tin-Lead, while the 1-770874-1 uses Tin. This variation does not affect connector mating performance or electrical circuit operation.

Q: Why is the 770874-2 marked as Last Time Buy?

A: Last Time Buy status indicates that the manufacturer has discontinued production of this part number. The 1-770874-1 is the active equivalent part, ensuring continued supply availability and supporting long-term design continuity.

Q: Does the 1-770874-1 meet RoHS requirements?

A: Yes. The 1-770874-1 is ROHS3 compliant. The 770874-2 is RoHS non-compliant. For applications requiring RoHS compliance, the 1-770874-1 is the appropriate selection.

Q: Are the connector housings and pin configurations identical?

A: Yes. Both parts share identical shrouded 4-wall housing design, 4-position male pin configuration, and 0.163" (4.14mm) pitch spacing in a 2-row arrangement. PCB footprints and mating interface dimensions are identical.

Q: What is the current rating for these connectors?

A: Current rating varies by wire gauge. Both the 770874-2 and 1-770874-1 share identical current rating specifications based on the wire gauge used in the application.

Q: Can these connectors be used interchangeably in high-temperature applications?

A: Yes. Both parts maintain identical operating temperature range specifications of -20°C to 105°C and UL94 V-0 material flammability rating, supporting equivalent thermal performance in specified temperature environments.
