Phoenix Contact 1776922 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1776922 is a 6-position vertical terminal block header with male pins, designed for solder termination and through-hole mounting. This component is part of the COMBICON MSTBV series and is actively manufactured. Terminal block headers are essential interconnection components in industrial control systems, power distribution panels, and modular electronic assemblies where reliable, field-replaceable connections are required. Equivalent parts may be necessary due to supply constraints, regional availability, or design standardization across manufacturing facilities.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1776922 is determined by the following critical parameters:

• Position Count: Must be 6 positions
• Pitch Tolerance: 0.197" (5.00mm) nominal, with 0.200" (5.08mm) acceptable within standard manufacturing tolerances for terminal block headers
• Connector Type: Header with male pins, shrouded (4 side) configuration
• Mounting Method: Through-hole solder termination
• Electrical Performance: Minimum 12 A current capacity and 300 V voltage rating (UL standard)
• Flammability Compliance: UL94 V-0 material rating
• Regulatory Status: ROHS3 compliance and EAR99 classification

The TE Connectivity AMP Connectors 796867-6 meets these substitution criteria. The pitch variance of 0.003" (0.08mm) between 5.00mm and 5.08mm is within acceptable tolerance for terminal block header applications and does not affect mechanical or electrical compatibility in standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both components are active products with ROHS3 compliance and EAR99 classification. The Phoenix Contact 1776922 and TE Connectivity 796867-6 are functionally equivalent for standard terminal block header applications.

Selection between these parts should be based on:

• Supply Availability: Both manufacturers maintain active production status with documented inventory
• Material Specification: If PBT housing is specifically required by design documentation, the Phoenix Contact part is the primary choice. If PA66/Nylon 6/6 housing is acceptable, the TE Connectivity part is suitable
• Electrical Margin: The TE Connectivity part provides 15 A current capacity versus the 12 A requirement, offering additional design margin
• Pitch Tolerance: The 0.003" (0.08mm) pitch difference is within standard PCB manufacturing tolerances and does not affect interchangeability in typical applications
• Contact Tail Length: The 0.016" (0.40mm) difference in contact tail length is negligible for standard through-hole solder applications

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 796867-6 be used as a direct replacement for the Phoenix Contact 1776922?

A: Yes. Both components share identical position count, orientation, termination method, mounting type, voltage rating, and flammability compliance. The pitch tolerance of 0.003" (0.08mm) and contact tail length variation of 0.016" (0.40mm) are within acceptable manufacturing tolerances for terminal block header applications.

Q: What is the significance of the pitch difference between 5.00mm and 5.08mm?

A: The 0.08mm difference represents approximately 1.6% variance and is within standard IEC and UL tolerance specifications for terminal block headers. This variance does not affect PCB pad spacing or mechanical fit in standard designs.

Q: Does the housing material difference affect electrical performance?

A: No. Both PBT and PA66/Nylon 6/6 materials meet UL94 V-0 flammability requirements and provide equivalent electrical insulation properties. Material selection is typically driven by specific environmental or mechanical requirements not specified in this comparison.

Q: Are both parts suitable for industrial control applications?

A: Yes. Both components are rated for 300 V UL voltage and meet ROHS3 compliance requirements. The TE Connectivity part provides additional current capacity (15 A versus 12 A), making it suitable for applications with higher current margins.

Q: What is the impact of the contact tail length difference?

A: The 0.016" (0.40mm) difference in contact tail length is negligible for standard through-hole solder applications. Both parts are designed for PCB mounting with standard solder reflow processes.

Q: Are there any packaging or inventory considerations?

A: Both parts are available in bulk packaging with active inventory. The Phoenix Contact 1776922 has 957 units in stock, while the TE Connectivity 796867-6 has 1155 units available.
