Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1776309-1 terminal block is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Parameters:

• Terminal Block Type: Eurostyle Terminal Strip
• Number of Circuits: 1
• Number of Wire Entries: 2
• Number of Rows: 2
• Voltage Rating: 400V
• Top Termination: Screws
• Bottom Termination: Closed
• Barrier Type: Enclosed
• Mounting Type: Chassis, Panel
• Material - Insulation: Polyamide (PA66), Nylon 6/6
• Operating Temperature Range: -35°C ~ 100°C

Parameters Permitting Variation:

• Current Rating (Amps): Substitutes with lower current ratings are acceptable for applications not requiring the full 34A capacity
• Wire Gauge: Substitutes with narrower wire gauge ranges are acceptable provided the application wire gauge falls within the substitute's specified range
• Terminal Screw Finish: Variations in chromate treatment (clear chromate versus non-hexavalent chromate) are acceptable
• Series Designation: Different series within the Buchanan product line are acceptable

The substitute part 1776301-6 meets all critical substitution parameters while operating at a reduced current rating of 16A and accommodating wire gauges 12-22 AWG.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity 1776301-6

The 1776301-6 serves as a functional equivalent for applications where the current requirement does not exceed 16A. Both parts maintain identical mechanical form factors, mounting configurations, and environmental operating ranges. Both components are ROHS3 compliant with MSL rating of 1 (Unlimited), ensuring compatibility with standard manufacturing and storage protocols.

The primary distinction between the main part and substitute is the current rating differential (34A versus 16A) and wire gauge accommodation (10-24 AWG versus 12-22 AWG). Selection of the 1776301-6 is appropriate for circuits operating at or below 16A with wire gauges within the 12-22 AWG range.

The 1776301-6 includes integrated fuse functionality, which represents an additional feature not present in the main part. This feature does not preclude substitution but should be evaluated within the context of the application's circuit protection requirements.

Both parts are manufactured by TE Connectivity AMP Connectors, ensuring consistent quality standards and manufacturing processes. The 1776301-6 maintains availability with 1039 pieces in stock, providing supply continuity for the obsolete 1776309-1.

Frequently Asked Questions (FAQ)

Q: Can the 1776301-6 substitute for the 1776309-1 in all applications?

A: The 1776301-6 substitutes for the 1776309-1 only in applications where the circuit current does not exceed 16A and the wire gauge falls within the 12-22 AWG range. Applications requiring the full 34A current capacity of the original part require alternative solutions.

Q: What is the significance of the wire gauge difference between the two parts?

A: The main part accommodates wire gauges from 10-24 AWG, while the substitute accommodates 12-22 AWG. The substitute cannot accept wire gauges smaller than 12 AWG (10 AWG and 11 AWG) or larger than 22 AWG (23 AWG and 24 AWG). Wire gauge selection must fall within the substitute's specified range for proper mechanical and electrical connection.

Q: Are both parts RoHS compliant?

A: Both the 1776309-1 and 1776301-6 are ROHS3 compliant, meeting current environmental and hazardous substance restrictions applicable to electronic components.

Q: What is the difference between the terminal screw finishes?

A: The main part features zinc with clear chromate finish, while the substitute features zinc with non-hexavalent chromate finish. Both finishes provide corrosion protection; the non-hexavalent chromate represents a more environmentally compliant alternative to hexavalent chromate.

Q: Does the integrated fuse in the 1776301-6 affect substitution compatibility?

A: The integrated fuse in the 1776301-6 is an additional feature. Substitution compatibility depends on whether the application circuit design accommodates or requires this fuse functionality. Applications not requiring fuse protection can still utilize the 1776301-6 without functional impact.

Q: What is the moisture sensitivity level, and why is it important?

A: Both parts carry an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions. These components can be stored and handled under standard environmental conditions without special moisture control measures.

Q: Are the mounting configurations identical between the two parts?

A: Both parts support identical mounting types: Chassis and Panel mounting. Physical form factors and mounting hole patterns are consistent, enabling direct mechanical substitution in existing installations.

Q: What is the operating temperature range for both parts?

A: Both the 1776309-1 and 1776301-6 operate across the temperature range of -35°C to 100°C, ensuring compatibility across standard industrial and commercial environmental conditions.
