Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 770170-1 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Connector type (Header)
• Number of positions (3)
• Pitch - mating (0.163" / 4.14mm)
• Mounting type (Through Hole)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Locking Ramp)

Electrical Compatibility:

• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 85°C)
• Contact material (Brass)
• Contact shape (Circular)

Material & Regulatory Compliance:

• Insulation material (Polyamide PA, Nylon)
• Flammability rating (UL94 V-0)
• Contact finish thickness (150.0µin / 3.81µm)

The substitute part 1-770170-0 maintains full equivalence across all mechanical and electrical parameters. Differences in contact finish composition (Tin-Lead versus Tin) and regulatory compliance status (RoHS and REACH) are noted but do not affect functional interchangeability in the specified application envelope.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-770170-0 serves as the direct functional equivalent to the 770170-1. Both parts share identical mechanical and electrical specifications within the Mini-Universal MATE-N-LOK series, ensuring pin-for-pin and footprint compatibility.

Product Status Consideration: The 770170-1 carries Last Time Buy status, indicating end-of-life production. The 1-770170-0 maintains Active product status with current manufacturing availability, making it the appropriate selection for new designs and ongoing procurement requirements.

Regulatory Compliance: The 1-770170-0 is RoHS Compliant, whereas the 770170-1 is RoHS non-compliant. For applications subject to RoHS directives or customer requirements mandating RoHS compliance, the 1-770170-0 is the required selection. The contact finish composition differs (Tin versus Tin-Lead), which aligns with RoHS compliance requirements while maintaining electrical and mechanical performance equivalence.

Inventory and Availability: The 1-770170-0 is currently in active production with 2990 pieces in stock, compared to the 770170-1 Last Time Buy status with 12679 pieces remaining. For long-term supply chain continuity, transition to the 1-770170-0 is recommended.

Frequently Asked Questions (FAQ)

Q: Are the 770170-1 and 1-770170-0 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including 3-position configuration, 0.163" (4.14mm) pitch, through-hole mounting, shrouded 4-wall design, and locking ramp fastening. PCB footprints and mating interface dimensions are identical.

Q: What is the difference between Tin-Lead and Tin contact finishes?

A: The 770170-1 uses Tin-Lead contact finish, while the 1-770170-0 uses Tin contact finish. Both finishes provide equivalent electrical conductivity and contact resistance performance. The Tin finish on the 1-770170-0 reflects RoHS compliance requirements. Contact finish thickness remains 150.0µin (3.81µm) on both parts.

Q: Can I use the 1-770170-0 as a direct replacement for the 770170-1 in existing designs?

A: Yes. The 1-770170-0 is electrically and mechanically equivalent to the 770170-1 across all specified parameters. No design modifications are required for substitution. The parts are functionally interchangeable in all applications within the -20°C to 85°C operating temperature range and 600VAC voltage rating.

Q: Why is the 770170-1 designated as Last Time Buy?

A: Last Time Buy status indicates that TE Connectivity has discontinued production of this part number. The 1-770170-0 represents the current production equivalent. Existing inventory of the 770170-1 will be depleted, and future procurement must transition to the 1-770170-0.

Q: What is the significance of RoHS compliance for the 1-770170-0?

A: RoHS (Restriction of Hazardous Substances) compliance indicates that the 1-770170-0 meets EU Directive 2011/65/EU requirements, restricting the use of lead and other hazardous substances. The 1-770170-0 is RoHS Compliant, while the 770170-1 is RoHS non-compliant. For applications subject to RoHS regulations or customer specifications, the 1-770170-0 is the required selection.

Q: Are there any performance differences between these two connectors?

A: No performance differences exist. Both connectors operate within the same temperature range (-20°C to 85°C), voltage rating (600VAC), and current capacity (varies by wire gauge). Contact material, insulation material, flammability rating, and all mechanical dimensions are identical.

Q: What is the current inventory status for each part?

A: The 770170-1 has 12679 pieces in stock but is Last Time Buy. The 1-770170-0 has 2990 pieces in stock and is in Active production status. For new projects and long-term supply assurance, the 1-770170-0 is the recommended selection.

Q: Can I mix 770170-1 and 1-770170-0 connectors in the same assembly?

A: Yes. Both connectors are mechanically and electrically equivalent and can be used interchangeably within the same assembly or system without functional impact.
