Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 770974-1 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (16)
• Number of rows (2)
• Pitch - mating (0.163" / 4.14mm)
• Row spacing - mating (0.163" / 4.14mm)
• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Fastening type (Locking Ramp)

Electrical Compatibility Parameters:

• Operating temperature range (-20°C ~ 85°C)
• Voltage rating (600VAC)
• Material flammability rating (UL94 V-0)

Termination Parameters:

• Termination method (Solder)

Substitute parts must maintain identical specifications across all listed parameters to ensure direct interchangeability in board-to-cable/wire applications without design modification or re-qualification.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-770974-0 is a direct functional equivalent to the 770974-1 across all mechanical and electrical parameters. Both connectors maintain identical specifications for connector type, contact configuration, pitch, mounting orientation, and operating characteristics.

The primary distinction between these parts is the contact finish specification and regulatory compliance status. The 770974-1 features Tin-Lead contact finish and carries RoHS non-compliant status, reflecting its Last Time Buy designation. The 1-770974-0 features Tin contact finish and is RoHS Compliant, indicating current production status and alignment with modern environmental regulations.

For new designs and ongoing production requiring RoHS compliance, the 1-770974-0 is the appropriate selection. For legacy systems or applications where RoHS compliance is not a requirement, either part provides equivalent electrical and mechanical performance. The contact finish difference (Tin-Lead versus Tin) does not affect functional interchangeability in standard solder termination applications.

Frequently Asked Questions (FAQ)

Q: Can the 1-770974-0 be used as a direct replacement for the 770974-1 in existing designs?

A: Yes. The 1-770974-0 is mechanically and electrically equivalent to the 770974-1. Both connectors share identical specifications for position count, pitch, mounting type, shrouding, and operating parameters. Direct substitution is possible without design modification.

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

A: The 770974-1 uses Tin-Lead contact finish, while the 1-770974-0 uses Tin contact finish. Both finishes provide equivalent electrical conductivity and solder wettability for through-hole solder termination. The Tin finish on the 1-770974-0 reflects compliance with lead-free manufacturing standards.

Q: Why is the 770974-1 designated as Last Time Buy?

A: Last Time Buy status indicates that TE Connectivity has discontinued production of this part number. The 1-770974-0 represents the current production equivalent, ensuring continued availability for applications requiring this connector configuration.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both parts are from the same Mini-Universal MATE-N-LOK series and maintain identical mechanical interfaces, electrical ratings, and functional characteristics. Existing mated connectors and cable assemblies are compatible with either header variant.

Q: What is the difference between RoHS compliant and non-compliant status?

A: RoHS compliance indicates that the product meets Restriction of Hazardous Substances regulations, limiting the use of lead and other hazardous materials. The 1-770974-0 is RoHS Compliant, while the 770974-1 is RoHS non-compliant. For applications subject to RoHS requirements, the 1-770974-0 is the appropriate selection.

Q: Can both parts be used interchangeably in the same production batch?

A: Yes. Both parts are functionally equivalent and can be used interchangeably in the same application. However, documentation and traceability records should reflect which part number is used in specific assemblies for compliance and maintenance purposes.

Q: What is the current inventory status for these parts?

A: The 770974-1 has 303,093 pieces in stock but is Last Time Buy. The 1-770974-0 has 2,032 pieces in stock and is Active production status. For long-term procurement planning, the 1-770974-0 is the recommended selection due to its active production status.
