Substitute Part Grouping Explanation

Substitution eligibility for the PST 1,3/ 3-LV-5,0 C1,2 is determined by the following critical parameters:

Position Count & Pitch: 3 positions at 0.197" (5.00mm) spacing
Mounting Configuration: Vertical through-hole solder termination
Electrical Performance: Current and voltage ratings sufficient for the application
Physical Compatibility: Contact tail length (0.138" / 4.60mm) and insulation height must accommodate PCB layout
Shroud Type: Partial shroud design for mechanical stability
Material & Compliance: UL94 V-0 flammability rating and RoHS compliance

The TE Connectivity AMP Connectors 282822-3 meets these substitution criteria with equivalent position count, pitch, mounting type, and termination style. Differences in shroud configuration (2-side shrouded vs. partial shroud) and electrical ratings are noted in the parameter comparison.

Engineering Selection Recommendations

The TE Connectivity 282822-3 is a functionally equivalent substitute for the obsolete Phoenix Contact 1704479 based on the following engineering criteria:

Compatibility Factors:

Identical position count (3), pitch (5.00mm), and mounting configuration (vertical through-hole solder)
Matching contact tail length (4.60mm) ensures PCB footprint compatibility
Both components meet UL94 V-0 flammability requirements
Both utilize tin contact mating finish

Compliance & Availability:

The 282822-3 maintains active product status with 4010 units in stock, ensuring supply chain continuity
ROHS3 compliance exceeds the RoHS Compliant status of the obsolete part
Both components carry EAR99 ECCN classification

Design Considerations:

The 282822-3 features 2-side shrouding compared to the partial shroud of the original part, providing enhanced mechanical stability
Insulation height difference (0.472" vs. 0.441") is 0.031" (0.80mm), requiring PCB layout verification
UL voltage rating (300 V) is lower than the IEC rating (400 V) of the original; application voltage requirements must be confirmed
UL current rating (15 A) exceeds the IEC rating (14.6A) of the original part

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 282822-3 be used as a direct replacement for the Phoenix Contact 1704479?

A: The 282822-3 is functionally equivalent for applications requiring 3-position, 5.00mm pitch vertical through-hole terminal blocks. The primary design difference is the shroud configuration (2-side shrouded vs. partial shroud) and a 0.031" increase in insulation height. PCB layout and mechanical clearance must be verified before implementation.

Q: What are the key electrical differences between these parts?

A: The original part specifies IEC ratings (14.6A at 400V), while the substitute uses UL ratings (15A at 300V). Applications operating above 300V or requiring the specific IEC certification must evaluate whether UL ratings are acceptable for the intended use.

Q: Are there packaging differences between these components?

A: The Phoenix Contact 1704479 is listed with unspecified packaging, while the TE Connectivity 282822-3 is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Does the increased insulation height of the 282822-3 affect PCB compatibility?

A: The 282822-3 has an insulation height of 0.472" compared to 0.441" for the original part, a difference of 0.031" (0.80mm). This must be verified against PCB layout constraints, particularly for applications with height-restricted mounting areas or adjacent components.

Q: Are both parts RoHS compliant?

A: Yes. The original part is RoHS Compliant, and the substitute is ROHS3 Compliant, which represents an updated compliance standard. Both meet environmental and hazardous substance restrictions.
