Key Parameters

Substitute Part Grouping Explanation

Substitution of the 770973-2 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Number of positions (14)
• Number of rows (2)
• Pitch spacing (0.163" / 4.14mm)
• Row spacing (0.163" / 4.14mm)
• Voltage rating (600VAC)
• Operating temperature range (-20°C ~ 105°C)

Mechanical Parameters:

• Mounting type (Through Hole, Right Angle)
• Shrouding configuration (Shrouded - 4 Wall)
• Termination method (Solder)
• Fastening type (Locking Ramp)
• Insulation material (Polyamide/Nylon)
• Contact material (Brass)
• Insulation color (White)

Compliance Parameters:

• Material flammability rating (UL94 V-0)
• Series compatibility (Mini-Universal MATE-N-LOK)

Parts meeting all these criteria are classified as direct substitutes. Variations in contact finish specifications or RoHS compliance status do not preclude substitution when all electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

The 1-770973-1 is a direct functional equivalent to the 770973-2 across all critical electrical and mechanical parameters. Both connectors share identical specifications for connector type, contact configuration, pitch spacing, mounting orientation, shrouding, and termination method.

The primary distinction between these parts is product status and regulatory compliance:

770973-2 (Main Part): Obsolete status with RoHS non-compliant designation. This part is no longer in active production.

1-770973-1 (Substitute): Active product status with RoHS Compliant certification. This part is currently manufactured and available for new designs and ongoing production.

The contact finish on the post differs slightly (Tin-Lead versus Tin), reflecting modern manufacturing standards. This variation does not affect electrical performance or mechanical compatibility within the specified operating parameters.

For applications requiring continued supply, design updates, or new implementations, the 1-770973-1 is the appropriate selection. The active product status ensures ongoing availability and support from TE Connectivity AMP Connectors.

Frequently Asked Questions (FAQ)

Q: Can the 1-770973-1 be used as a direct replacement for the 770973-2 in existing designs?

A: Yes. The 1-770973-1 meets all electrical and mechanical specifications of the 770973-2. Pin configuration, pitch spacing, voltage rating, operating temperature range, and mounting characteristics are identical. The connector will function equivalently in board-to-cable/wire applications.

Q: What is the significance of the RoHS compliance difference between these parts?

A: The 770973-2 is RoHS non-compliant, while the 1-770973-1 is RoHS Compliant. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the 1-770973-1 is the required selection. The compliance difference reflects manufacturing process updates rather than functional capability changes.

Q: Are there packaging differences between the 770973-2 and 1-770973-1?

A: The 770973-2 packaging specification is not provided in the available data. The 1-770973-1 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Does the contact finish variation (Tin-Lead versus Tin) affect performance?

A: No. Both contact finishes meet the specified electrical and mechanical requirements. The Tin finish on the 1-770973-1 reflects current manufacturing standards and RoHS compliance. Solder joint reliability and electrical conductivity remain equivalent.

Q: Why is the 770973-2 listed as obsolete?

A: The 770973-2 has been superseded by the 1-770973-1 in TE Connectivity's product line. The 1-770973-1 offers identical functionality with active production status and modern compliance certifications.

Q: Can I mix 770973-2 and 1-770973-1 connectors in the same assembly?

A: Yes. Both connectors are mechanically and electrically compatible within the Mini-Universal MATE-N-LOK series. They share identical mating interfaces and contact configurations.

Q: What inventory status should I expect for each part?

A: The 770973-2 has 1048 pieces in stock (obsolete status). The 1-770973-1 has 1076 pieces in stock (active status). For long-term supply planning, prioritize the 1-770973-1 due to its active product designation.
