Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 770967-1 is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (3)
• Pitch spacing (0.163" / 4.14mm)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Fastening mechanism (Locking Ramp)

Electrical Compatibility Parameters:

• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 85°C)
• Contact material (Brass)
• Insulation material (Polyamide/Nylon)

Termination Parameters:

• Solder termination method
• Contact post length (0.145" / 3.68mm)
• Insulation height (0.225" / 5.72mm)

The substitute part 1-770967-0 maintains full equivalence across all mechanical, electrical, and termination parameters. The primary distinction is the contact finish specification and product status transition from obsolete to active.

Engineering Selection Recommendations

The TE Connectivity 1-770967-0 is the direct functional equivalent and recommended substitute for the obsolete 770967-1. Selection of the substitute part is justified on the following engineering and compliance grounds:

Product Status Transition: The 770967-1 is classified as obsolete, creating supply chain risk for ongoing production and field service requirements. The 1-770967-0 maintains active product status with significantly higher inventory availability (22,500 units versus 1,313 units), ensuring long-term supply continuity.

Regulatory Compliance: The substitute part achieves ROHS3 compliance, whereas the main part is RoHS non-compliant. This compliance improvement aligns with current regulatory requirements for electronic components in most markets and eliminates potential restrictions on future procurement and deployment.

Electrical and Mechanical Equivalence: All critical electrical parameters (600VAC voltage rating, -20°C to 85°C operating temperature range) and mechanical specifications (3-position, 4.14mm pitch, through-hole right-angle mounting, shrouded 4-wall design, locking ramp fastening) are identical between the two parts.

Contact Finish Specification: The substitute part specifies pure tin contact finish in place of the tin-lead finish on the main part. Both finishes maintain the identical 150.0µin (3.81µm) thickness specification and provide equivalent electrical performance and reliability for the 600VAC, general-purpose application profile.

Functional Compatibility: The substitute part is fully compatible with existing mating connectors, cable assemblies, and printed circuit board layouts designed for the 770967-1, requiring no design modifications or re-qualification of interconnect systems.

Frequently Asked Questions (FAQ)

Q: Can the 1-770967-0 be used as a direct replacement for the 770967-1 without PCB layout modifications?

A: Yes. The 1-770967-0 maintains identical mechanical dimensions, mounting configuration (through-hole right-angle), pitch spacing (0.163" / 4.14mm), and shrouding design. No PCB layout changes are required for substitution.

Q: What is the difference between the tin-lead finish on the 770967-1 and the tin finish on the 1-770967-0?

A: Both finishes provide equivalent electrical conductivity and contact reliability at the specified 600VAC rating. The tin finish on the substitute part eliminates lead content, supporting RoHS3 compliance. Both maintain the same 150.0µin (3.81µm) thickness specification.

Q: Are the mating connectors and cable assemblies compatible between the two parts?

A: Yes. Both parts are from the same Mini-Universal MATE-N-LOK series with identical contact type (male pin), number of positions (3), and pitch spacing (0.163" / 4.14mm). Existing mating connectors and cable assemblies are fully compatible with the substitute part.

Q: What is the significance of the RoHS3 compliance on the 1-770967-0?

A: RoHS3 compliance indicates the substitute part meets current Restriction of Hazardous Substances regulations, eliminating restrictions on procurement and deployment in regulated markets. The obsolete 770967-1 is RoHS non-compliant and may face restrictions in future applications.

Q: Is the operating temperature range identical between the two parts?

A: Yes. Both parts operate across the identical temperature range of -20°C to 85°C, with identical UL94 V-0 flammability rating and insulation material composition (Polyamide/Nylon).

Q: What is the difference in packaging between the two parts?

A: The 770967-1 packaging is not specified in available documentation. The 1-770967-0 is supplied in bulk packaging, which is standard for this connector category and supports efficient inventory management and assembly operations.

Q: Why is inventory availability significantly higher for the 1-770967-0?

A: The 1-770967-0 is an active product with ongoing production and distribution, whereas the 770967-1 is obsolete with limited remaining stock. The higher inventory level (22,500 units) for the substitute part reflects its active market status and ensures supply continuity for new designs and field service applications.

Q: Are there any electrical performance differences between the two parts?

A: No. Both parts maintain identical voltage rating (600VAC), current rating (varies by wire gauge), and operating temperature range (-20°C to 85°C). Electrical performance is equivalent for all general-purpose applications.

Q: Can the 1-770967-0 be used in existing designs without re-qualification?

A: Yes. The substitute part is mechanically and electrically equivalent to the main part across all critical parameters. Existing designs require no modification or re-qualification for substitution.
