Phoenix Contact 1727081 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1727081 is a 9-position wire-to-board terminal block with side entry, 3.81mm pitch, and through-hole mounting. This component is designed for horizontal board orientation with screw-based wire termination using a rising cage clamp mechanism. The part is currently active in production with 935 units in stock. Alternative equivalent parts may be required due to supply constraints, design standardization across manufacturing facilities, or specific application requirements for interchangeable terminal block solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1727081 is determined by the following critical parameters:

• Position Count & Pitch: Must be 9 positions at 0.150" (3.81mm) pitch for PCB footprint compatibility
• Mating Orientation: Must be horizontal with board configuration
• Mounting Method: Must be through-hole mounting
• Wire Termination: Must use screw-based rising cage clamp mechanism
• Electrical Ratings: Voltage rating of 300 V is mandatory; current rating must meet or exceed 14.6 A
• Wire Gauge Compatibility: Must accommodate 16-30 AWG wire range minimum
• Mechanical Interface: Screw thread specification and torque range must be compatible with assembly procedures

The TE Connectivity AMP Connectors part 284392-9 meets these substitution criteria with the following considerations: identical position count, pitch, orientation, mounting type, and termination method; equivalent voltage rating; and compatible wire gauge range with minor variation in current specification.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1727081 and TE Connectivity 284392-9 are active products with ROHS3 compliance. Selection between these parts should be based on the following factors:

Phoenix Contact 1727081: Select when the application requires the specified 14.6 A current rating, M2 screw thread specification, or when standardization on the COMBICON MKDS series is required. This part is the primary choice for designs validated against Phoenix Contact specifications.

TE Connectivity 284392-9: Select as an equivalent substitute when supply of the primary part is constrained. The 12 A current rating is suitable for applications not requiring the full 14.6 A capacity. The M3 screw thread and slightly different housing material (PA66 vs. PA) represent minor mechanical variations that do not affect electrical performance or PCB footprint compatibility. The wider wire gauge acceptance (14-30 AWG vs. 16-30 AWG) provides additional flexibility for wire termination.

Both parts carry identical voltage ratings, position counts, pitch specifications, and mounting configurations, ensuring direct PCB footprint compatibility and functional interchangeability within the specified electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 284392-9 be used as a direct replacement for the Phoenix Contact 1727081 on existing PCBs?

A: Yes, for PCB footprint compatibility. Both parts have identical position counts (9), pitch (3.81mm), through-hole mounting, and horizontal board orientation. However, the M3 screw thread on the TE part differs from the M2 thread on the Phoenix Contact part, requiring verification that assembly equipment and torque specifications are compatible with M3 fasteners.

Q: What is the significance of the current rating difference (14.6 A vs. 12 A)?

A: The Phoenix Contact part is rated for 14.6 A while the TE part is rated for 12 A. Applications requiring continuous current above 12 A must use the Phoenix Contact part. For applications operating at or below 12 A, the TE part is electrically equivalent.

Q: Are the housing materials functionally equivalent?

A: Both use polyamide nylon materials. The Phoenix Contact part specifies PA (polyamide) while the TE part specifies PA66 (polyamide 6/6). Both materials provide equivalent electrical insulation and mechanical properties for this terminal block application. Material selection does not affect electrical performance or interchangeability.

Q: Does the wire gauge range difference affect compatibility?

A: The TE part accepts 14-30 AWG while the Phoenix Contact part accepts 16-30 AWG. The TE part's wider range provides additional flexibility. If your application uses 14-15 AWG wire, only the TE part is suitable. For 16-30 AWG applications, both parts are compatible.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both the Phoenix Contact 1727081 and TE Connectivity 284392-9 are ROHS3 compliant and actively manufactured. Both carry EAR99 ECCN classification and identical HTSUS codes, confirming regulatory equivalence for procurement and deployment.
