Phoenix Contact 1776883 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1776883 is a 2-position terminal block header with male pins, shrouded on 4 sides, designed for vertical through-hole mounting with 5.00mm pitch. This component is part of the COMBICON MSTBV series and is currently in active production status. The device supports IEC ratings of 12A at 400V and UL ratings of 12A at 300V, making it suitable for industrial control and power distribution applications. Identifying equivalent substitute parts becomes necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility is required across manufacturing locations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1776883 is determined by the following critical parameters:

Primary Substitution Criteria:

• 2-position configuration with male pins
• Shrouded (4-side) design
• Vertical through-hole mounting orientation
• 5.00mm pitch spacing (±0.08mm tolerance acceptable for mechanical fit)
• Solder termination style
• UL94 V-0 flammability rating
• ROHS3 compliance
• Tin contact mating finish

Electrical Compatibility Threshold:

• Minimum UL current rating: 12A
• Minimum UL voltage rating: 300V
• IEC ratings may vary based on regional application requirements

The TE Connectivity AMP Connectors part 796867-2 qualifies as a substitute based on matching the core mechanical and electrical parameters within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors 796867-2 is qualified as a direct substitute for the Phoenix Contact 1776883 based on the following engineering factors:

Compliance and Certification Alignment: Both parts maintain ROHS3 compliance and UL94 V-0 flammability ratings, meeting regulatory requirements for industrial applications. Both components are in active production status, ensuring continued availability and supply chain stability.

Electrical Performance: The TE Connectivity part exceeds the electrical requirements of the Phoenix Contact original, providing 15A UL current capacity versus the 12A requirement. Voltage ratings are identical at 300V UL. This performance margin provides additional design flexibility without compromising application safety.

Mechanical Compatibility: Pitch spacing differs by 0.08mm (5.00mm versus 5.08mm), which falls within standard PCB manufacturing tolerances for through-hole component placement. Insulation height, mounting orientation, and shroud configuration are identical. Contact tail length variation (3.90mm versus 4.60mm) is minor and accommodates standard solder joint formation on PCB designs.

Material Consideration: Housing material differs (PBT versus PA66 Nylon 6/6), but both materials achieve identical flammability ratings. Selection between these materials should be based on specific application environmental conditions, such as chemical exposure or temperature cycling requirements.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 796867-2 be used as a direct replacement on existing PCB designs?

A: Yes. The mechanical footprint is compatible within standard PCB manufacturing tolerances. The 0.08mm pitch variation and 0.40mm contact tail length difference do not prevent proper solder joint formation or mating with standard connectors. PCB layout verification is recommended for high-density designs.

Q: Are there electrical performance differences between these parts?

A: The TE Connectivity part provides higher current capacity (15A versus 12A at UL ratings). Voltage ratings are identical. For applications operating at or near the 12A limit, the substitute part provides additional thermal margin and design safety.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant and carry UL94 V-0 flammability ratings. Both are in active production status with established supply chains.

Q: What is the significance of the housing material difference?

A: The Phoenix Contact uses PBT while the TE Connectivity uses PA66 Nylon 6/6. Both materials achieve the same flammability rating. Material selection should consider application-specific factors such as chemical resistance, moisture absorption, and operating temperature range. The TE Connectivity part specifies an operating temperature range of -40°C to 110°C.

Q: Are there any packaging or inventory considerations?

A: The Phoenix Contact 1776883 is available in bulk packaging with 950 pieces in stock. The TE Connectivity 796867-2 is available in bulk packaging with 2857 pieces in stock, providing greater availability for high-volume requirements.

Q: What should be verified before implementing this substitution in production?

A: Confirm PCB layout compatibility with the minor pitch and contact tail length variations. Verify mating connector compatibility with both parts. Validate solder joint quality and electrical continuity in prototype builds. Confirm environmental and chemical compatibility with the PA66 housing material if the application involves exposure to specific solvents or elevated temperatures.
