TE Connectivity 770973-1 Rectangular Connector Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity 770973-1 is a right-angle rectangular connector header from the Mini-Universal MATE-N-LOK series. This through-hole, shrouded 14-position connector is designed for board-to-cable/wire applications with solder termination and locking ramp fastening. The part is classified as obsolete, making identification of active equivalent components essential for ongoing production and maintenance applications. Substitute parts must maintain identical electrical and mechanical specifications to ensure direct interchangeability without circuit redesign or board modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 770973-1 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility:

• Contact type (Male Pin)
• Number of positions (14)
• Number of rows (2)
• Pitch specifications (0.163" mating pitch and row spacing)
• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 85°C)

Mechanical Compatibility:

• Connector type (Header)
• Mounting configuration (Through Hole, Right Angle)
• Shrouding design (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening mechanism (Locking Ramp)

Regulatory Compliance:

• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The substitute part 1-770973-0 maintains all critical electrical and mechanical parameters. The primary distinction is product status: 770973-1 is obsolete while 1-770973-0 is active, with improved inventory availability and ongoing manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1-770973-0 is the direct active equivalent for the obsolete 770973-1 connector header. Both parts are manufactured by TE Connectivity within the Mini-Universal MATE-N-LOK series and maintain identical electrical, mechanical, and dimensional specifications.

Product Status Consideration: The 770973-1 is classified as obsolete, while 1-770973-0 maintains active status with TE Connectivity. Active product status ensures ongoing manufacturer support, documented specifications, and supply chain availability. For new designs and production continuity, 1-770973-0 is the appropriate selection.

Compliance and Certification: Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.69.4040). No compliance gaps exist between the main part and substitute.

Contact Finish Specification: The primary technical distinction is contact finish composition. The 770973-1 specifies Tin-Lead finish, while 1-770973-0 specifies Tin finish. Both finishes maintain the identical 150.0µin (3.81µm) thickness specification and provide equivalent electrical performance and solder joint reliability for board-to-cable/wire applications.

Packaging and Inventory: The 1-770973-0 is available in bulk packaging with 2028 pieces in stock, compared to 1310 pieces of the obsolete 770973-1. Bulk packaging and higher inventory levels support production requirements and reduce lead time risk.

Frequently Asked Questions (FAQ)

Q: Can 1-770973-0 be used as a direct replacement for 770973-1 in existing assemblies?

A: Yes. The 1-770973-0 maintains identical electrical and mechanical specifications across all critical parameters: 14-position, 2-row configuration; 0.163" (4.14mm) pitch; through-hole right-angle mounting; shrouded 4-wall design; solder termination; and locking ramp fastening. No circuit redesign or board modification is required.

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

A: The 770973-1 specifies Tin-Lead finish while 1-770973-0 specifies Tin finish. Both finishes are applied at identical thickness (150.0µin / 3.81µm) and provide equivalent electrical conductivity and solder joint reliability. Tin finish represents a lead-free alternative consistent with ROHS3 compliance requirements.

Q: Are both parts ROHS3 compliant?

A: Yes. Both 770973-1 and 1-770973-0 are ROHS3 compliant. The contact finish difference (Tin-Lead versus Tin) does not affect overall ROHS compliance status for either part.

Q: Why is 770973-1 classified as obsolete?

A: Product obsolescence is determined by manufacturer discontinuation decisions. The 1-770973-0 represents the active equivalent within the same series and maintains all functional specifications. For ongoing production and new designs, 1-770973-0 is the appropriate selection.

Q: What is the voltage and temperature rating for these connectors?

A: Both parts are rated for 600VAC operation across an operating temperature range of -20°C to 85°C. These specifications are identical and support general-purpose board-to-cable/wire applications.

Q: Does packaging type affect connector performance?

A: No. The 770973-1 is supplied in standard packaging while 1-770973-0 is supplied in bulk packaging. Packaging type does not affect electrical performance, mechanical fit, or functional compatibility. Bulk packaging provides cost and logistics advantages for production environments.

Q: What is the moisture sensitivity level (MSL) for these parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. These connectors do not require special moisture control during storage, handling, or assembly.

Q: Are these connectors suitable for high-current applications?

A: Current rating varies by wire gauge. The connector specifications do not define a fixed current limit; current capacity is determined by the wire gauge and termination method used in the specific application. Consult wire gauge specifications and application requirements for current capacity determination.
