PST 1,3/ 3-LV-5,0 C2 (1704466) Equivalent & Substitute Parts

Part Overview

The Phoenix Contact PST 1,3/ 3-LV-5,0 C2 (1704466) is a 3-position terminal block header with male pins and partial shroud, designed for vertical through-hole mounting with 0.197" (5.00mm) pitch spacing. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for terminal block headers is determined by strict alignment of electrical and mechanical parameters. The primary criteria for the PST 1,3/ 3-LV-5,0 C2 are:

• Number of positions: 3
• Pitch spacing: 0.197" (5.00mm)
• Header orientation: Vertical
• Mounting type: Through hole with solder termination
• Contact tail length: 0.138" (4.60mm)
• Electrical ratings: Current and voltage specifications per IEC or UL standards
• Flammability compliance: UL94 V-0

The substitute part TE Connectivity 282822-3 meets these core mechanical and electrical requirements. Differences in shroud configuration (partial versus 2-side shrouded) and housing material composition do not prevent functional substitution when PCB layout and connector mating requirements are compatible.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 282822-3 is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for applications currently using the obsolete Phoenix Contact 1704466. Both components share identical pitch spacing, contact tail length, and UL voltage rating of 300V. The TE Connectivity substitute provides higher UL current rating (15A versus 10A), which represents improved electrical capacity for the same form factor.

The 0.031" (0.80mm) difference in insulation height and the transition from partial shroud to 2-side shrouded configuration require PCB layout verification to ensure mechanical clearance and connector mating compatibility. Housing material composition differs (Polyamide PA versus PA66), but both maintain UL94 V-0 flammability compliance.

Selection of the TE Connectivity 282822-3 is appropriate for new designs and legacy system updates where supply of the original Phoenix Contact component is no longer available.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 282822-3 be used as a direct replacement for the Phoenix Contact 1704466?

A: Functional substitution is possible when pitch spacing, contact tail length, and electrical ratings are compatible with the application. The identical 5.00mm pitch and 4.60mm contact tail length ensure mechanical fit on standard PCB layouts. Verify that the increased insulation height (0.472" versus 0.441") and 2-side shroud configuration do not conflict with adjacent components or connector mating requirements.

Q: What is the difference between partial shroud and 2-side shrouded configurations?

A: Partial shroud provides insulation on limited surfaces, while 2-side shrouded offers protection on two opposing sides. This affects mechanical stability and EMI shielding characteristics. PCB layout and connector design must accommodate the different shroud geometry.

Q: Are both parts RoHS compliant?

A: Yes. The Phoenix Contact 1704466 is RoHS Compliant. The TE Connectivity 282822-3 is ROHS3 Compliant, representing a more recent compliance standard. Both meet RoHS requirements for hazardous substance restrictions.

Q: What is the current rating difference between these parts?

A: The Phoenix Contact 1704466 is rated for 10A (UL), while the TE Connectivity 282822-3 is rated for 15A (UL). Both maintain 300V voltage rating. The higher current capacity of the substitute part does not create compatibility issues in applications designed for the lower rating.

Q: How do the housing materials differ?

A: Phoenix Contact uses Polyamide (PA), while TE Connectivity uses Polyamide (PA66), also known as Nylon 6/6. Both materials maintain UL94 V-0 flammability rating. PA66 offers slightly different mechanical and thermal properties but is functionally equivalent for this application category.

Q: Is the insulation height difference significant?

A: The 0.031" (0.80mm) increase in insulation height on the TE Connectivity part requires verification against PCB layout constraints and adjacent component clearances. This difference may affect board-level assembly in space-constrained designs.
