Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1781027 is determined by the following critical parameters:

• 6-position configuration with 0.200" (5.08mm) pitch spacing
• Female socket plug type with free-hanging in-line mounting
• Screw termination technology
• Wire gauge compatibility within 12-30 AWG range
• UL94 V-0 flammability rating
• Tin contact mating finish
• Retention latches on non-wire side
• RoHS3 and REACH compliance status

The identified substitute parts meet these core electrical and mechanical requirements. Variations in secondary parameters such as operating temperature range, specific torque values, or housing material composition do not preclude substitution when primary functional parameters align.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and full compliance with RoHS3 and REACH regulations. Selection between the Phoenix Contact 1781027 and its substitutes is based on availability, wire gauge requirements, and current rating specifications.

The On Shore Technology OSTTJ065153 supports the full 15A UL current rating and accommodates wire gauges from 12-24 AWG. This part is suitable for applications requiring standard wire gauge ranges and is available in higher inventory quantities (6901 units).

The Amphenol Anytek TJ0651560000G maintains the 180° plug wire entry orientation and rising cage clamp termination identical to the original Phoenix Contact design. This part is rated for 12A UL current and supports wire gauges from 12-24 AWG. It is available in moderate inventory (2269 units).

Selection should prioritize the specific wire gauge and current requirements of the target application, along with connector orientation and termination method compatibility.

Frequently Asked Questions (FAQ)

Q: Can the On Shore Technology OSTTJ065153 be used as a direct replacement for the Phoenix Contact 1781027?

A: The OSTTJ065153 is mechanically and electrically compatible for applications requiring 6-position, 5.08mm pitch female socket plugs with screw termination. Both parts support 15A UL current rating and 300V UL voltage rating. Wire gauge compatibility is 12-24 AWG for the OSTTJ065153 versus 12-30 AWG for the original part. Verify that your application wire gauges fall within the 12-24 AWG range before substitution.

Q: What is the difference between the Amphenol Anytek TJ0651560000G and the Phoenix Contact 1781027?

A: Both parts feature identical 180° plug wire entry orientation and screw rising cage clamp termination. The primary difference is the UL current rating: the Amphenol part is rated for 12A versus 15A for the Phoenix Contact. Both support 300V UL voltage and accommodate 12-24 AWG wire gauges. Select the Amphenol part only if your application current requirements do not exceed 12A.

Q: Are all three parts RoHS3 and REACH compliant?

A: Yes. The Phoenix Contact 1781027, On Shore Technology OSTTJ065153, and Amphenol Anytek TJ0651560000G are all RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What wire gauge range should I verify before selecting a substitute?

A: The Phoenix Contact 1781027 supports 12-30 AWG (0.2-2.5mm²). The On Shore Technology OSTTJ065153 and Amphenol Anytek TJ0651560000G both support 12-24 AWG. If your application requires wire gauges smaller than 0.34mm² or larger than 2.5mm², the original Phoenix Contact part may be necessary.

Q: Do all three parts have retention latches?

A: Yes. All three parts feature retention latches on the non-wire side, providing consistent mechanical retention across substitution options.

Q: What is the screw torque specification for each part?

A: The Phoenix Contact 1781027 specifies 0.5-0.6 Nm (4.4-5.3 Lb-In). Both the On Shore Technology OSTTJ065153 and Amphenol Anytek TJ0651560000G specify 0.56 Nm (5.0 Lb-In). These values are within compatible ranges for M3 screw termination.
