TE Connectivity 770968-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 770968-1 is a rectangular connector header manufactured under the Mini-Universal MATE-N-LOK series. This through-hole, right-angle connector features 4 positions arranged in 2 rows with 0.163" (4.14mm) pitch spacing, designed for board-to-cable/wire applications with solder termination and locking ramp fastening. The connector incorporates shrouded 4-wall construction with male pin contacts and operates across a temperature range of -20°C to 85°C at 600VAC rating.

The 770968-1 carries a Last Time Buy product status, indicating discontinued manufacturing. Identifying equivalent substitute parts is necessary to maintain design continuity and ensure component availability for ongoing production and field service requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 770968-1 is determined by strict equivalence across mechanical and electrical parameters. All substitute parts must maintain identical specifications for connector type, contact configuration, pitch spacing, mounting orientation, shrouding design, and termination method. These parameters establish physical and electrical compatibility with mating connectors and printed circuit board layouts.

The following parameters establish substitution boundaries:

• Connector Type: Header (male pin contact)
• Position Configuration: 4 positions in 2 rows
• Pitch Spacing: 0.163" (4.14mm) mating pitch and row spacing
• Mounting: Through-hole, right-angle orientation
• Shrouding: 4-wall shrouded construction
• Termination: Solder
• Fastening: Locking ramp mechanism
• Voltage Rating: 600VAC minimum
• Temperature Range: -20°C minimum to 85°C minimum

Variations in contact finish material, contact finish thickness, RoHS compliance status, and product lifecycle status do not preclude substitution when all mechanical and primary electrical parameters remain constant.

Engineering Selection Recommendations

1-770968-0 (Direct Substitute - Recommended)

The 1-770968-0 is the primary substitute for the 770968-1. This part maintains complete mechanical and electrical equivalence across all critical parameters including connector type, position configuration, pitch spacing, mounting orientation, and termination method. The 1-770968-0 carries Active product status, ensuring ongoing availability and supply chain continuity. The part is RoHS Compliant, meeting current environmental and regulatory requirements. Contact finish differs only in material composition (Tin versus Tin-Lead) and thickness remains equivalent at 150.0µin (3.81µm), maintaining electrical performance characteristics. Current inventory of 3,300 pieces supports immediate procurement requirements.

770968-2 (Similar Substitute - Conditional)

The 770968-2 provides mechanical and electrical equivalence with extended operating temperature capability to 105°C, compared to the 770968-1 specification of 85°C. This part is suitable for applications requiring elevated temperature performance. The 770968-2 features gold plating on mating contacts (30.0µin thickness) versus tin-lead plating on the main part, providing enhanced corrosion resistance in demanding environments. The part carries Last Time Buy status, indicating limited future availability. REACH Affected status requires compliance verification for specific end-use applications. Current inventory of 282,484 pieces provides substantial supply availability.

Selection Criteria:

• For standard applications with standard temperature requirements and RoHS compliance mandates: select 1-770968-0
• For applications requiring extended temperature operation or enhanced contact corrosion resistance: select 770968-2
• Verify REACH compliance requirements before selecting 770968-2 for regulated applications

Frequently Asked Questions (FAQ)

Q: Can the 1-770968-0 be used as a direct replacement for the 770968-1 in existing designs?

A: Yes. The 1-770968-0 maintains complete mechanical and electrical compatibility with the 770968-1. All critical parameters including connector type, position count, pitch spacing, mounting configuration, and termination method are identical. The contact finish material difference (Tin versus Tin-Lead) does not affect functional compatibility or electrical performance.

Q: What is the primary difference between the 770968-1 and 770968-2?

A: The 770968-2 extends the operating temperature range to 105°C compared to the 770968-1 specification of 85°C. Additionally, the 770968-2 features gold plating on mating contacts versus tin-lead plating on the 770968-1. Both parts are mechanically and electrically equivalent for all other parameters.

Q: Does the contact finish difference between these parts affect mating performance?

A: No. All substitute parts maintain equivalent contact finish thickness at 150.0µin (3.81µm) on the post termination. Variations in mating contact finish material (Tin-Lead, Tin, or Gold) do not affect mechanical mating or electrical continuity when used with compatible receptacle connectors from the same Mini-Universal MATE-N-LOK series.

Q: Which substitute part should be selected for new designs?

A: The 1-770968-0 is recommended for new designs. This part carries Active product status, ensuring long-term availability and supply chain stability. The 1-770968-0 is RoHS Compliant, meeting current environmental regulations. Both the 770968-1 and 770968-2 carry Last Time Buy status, indicating discontinued manufacturing.

Q: Are there any compliance differences between the substitute parts?

A: Yes. The 1-770968-0 is RoHS Compliant, while both the 770968-1 and 770968-2 are RoHS non-compliant. The 770968-2 carries REACH Affected status, requiring compliance verification for specific applications. The 1-770968-0 lists REACH status as Vendor Undefined. Applications subject to RoHS or REACH regulations should select the 1-770968-0.

Q: What is the significance of the Last Time Buy status on the 770968-1 and 770968-2?

A: Last Time Buy status indicates that the manufacturer has discontinued production of these parts. Existing inventory will be depleted without replenishment. The 1-770968-0 carries Active status, confirming ongoing production and availability. For long-term supply security, the 1-770968-0 is the appropriate selection.

Q: Can the 770968-2 be used in applications with standard temperature requirements?

A: Yes. The 770968-2 is fully compatible with applications operating within the standard -20°C to 85°C temperature range. The extended temperature capability to 105°C provides additional margin for thermal stress conditions but does not restrict use in standard temperature applications. Selection should be based on application requirements, compliance mandates, and supply availability.

Q: Are all substitute parts packaged identically?

A: Yes. All three parts (770968-1, 1-770968-0, and 770968-2) are packaged in Bulk format. Packaging configuration does not differ between the main part and substitute parts.

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

A: The 770968-1 has 442,216 pieces in stock. The 1-770968-0 has 3,300 pieces in stock. The 770968-2 has 282,484 pieces in stock. Inventory levels should be verified at time of procurement to confirm availability.
