Phoenix Contact 1991367 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1991367 is a 9-position terminal block plug designed for unshrouded headers with 0.197" (5.00mm) pitch spacing. This component features 90° wire entry, screw-type rising cage clamp termination, and free-hanging in-line mounting. The part is actively produced and RoHS compliant, making it suitable for industrial control and power distribution applications requiring reliable electrical connections.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when system design requires components from alternative manufacturers while maintaining equivalent electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity AMP Connectors 1546018-9 qualifies as a functional equivalent based on the following critical parameters:

• Position Count & Pitch: Both parts provide 9 positions at 0.197" (5.00mm) pitch, ensuring mechanical compatibility with corresponding unshrouded headers
• Wire Entry Angle: Both feature 90° plug wire entry, maintaining identical installation geometry
• Termination Method: Both use screw-type rising cage clamp termination, providing equivalent wire retention and electrical contact
• Mounting Configuration: Both are free-hanging in-line plugs with identical form factors
• Electrical Performance: The substitute part meets or exceeds the main part's current and voltage requirements (12A UL rating vs. 12A IEC; 300V UL vs. 250V IEC)
• Wire Compatibility: The substitute accepts 14-30 AWG (0.05-2mm²), which encompasses the main part's 12-26 AWG range within the critical 0.2-2.5mm² cross-section
• Compliance: Both parts are RoHS compliant and carry MSL 1 rating

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1991367 and TE Connectivity 1546018-9 are active production components with current RoHS compliance certifications. The TE Connectivity substitute provides equivalent electrical performance with higher voltage rating (300V vs. 250V) and maintains mechanical compatibility through identical pitch, position count, and wire entry geometry.

The primary design consideration is screw size variance: the Phoenix Contact uses M2.6 fasteners while the TE Connectivity uses M3. This difference requires verification that the mating header accommodates the larger M3 screw without mechanical interference. Wire gauge compatibility is maintained within the critical 0.2-2.5mm² range specified for the main part.

Selection between these parts should be based on availability, supply chain requirements, and confirmation that the mating connector housing accepts the substitute's M3 screw specification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 1546018-9 directly replace the Phoenix Contact 1991367 in existing assemblies?

A: Mechanical and electrical compatibility is confirmed for the 9-position, 5mm pitch configuration. However, the M3 screw size on the substitute differs from the M2.6 on the main part. Verify that the mating unshrouded header is designed to accept M3 fasteners before substitution.

Q: Are there wire gauge limitations when using the substitute part?

A: The TE Connectivity part accepts 14-30 AWG (0.05-2mm²). For applications using the Phoenix Contact's full 12-26 AWG range, confirm that wire gauges remain within the 0.2-2.5mm² cross-section to maintain equivalent current-carrying capacity.

Q: What is the difference in wire strip length between these parts?

A: The Phoenix Contact requires exactly 5mm wire strip length. The TE Connectivity allows 4-6mm, providing a tolerance range. Ensure wire preparation procedures accommodate this specification when switching parts.

Q: Do both parts meet the same compliance standards?

A: Both parts are RoHS compliant and carry MSL 1 ratings. The Phoenix Contact is RoHS compliant, while the TE Connectivity is ROHS3 compliant. Both carry EAR99 ECCN classification and identical HTSUS codes (8536.90.4000).

Q: What is the voltage and current rating difference?

A: The Phoenix Contact is rated 12A at 250V (IEC standard). The TE Connectivity is rated 12A at 300V (UL standard). The substitute provides higher voltage margin while maintaining equivalent current capacity.
