Engineering Selection Recommendations

The Phoenix Contact 3213604 is a direct substitute for the 3031665 based on electrical and mechanical parameter equivalence. Both components maintain identical IEC and UL current and voltage ratings, terminal geometry, and material specifications. The 3213604 operates within the CLIPLINE PTS series with Active product status, ensuring continued availability and supply chain stability compared to the Last Time Buy status of the original part.

The wire gauge range difference (10-24 AWG for 3213604 versus 10-28 AWG for 3031665) represents a subset accommodation. Applications utilizing wire gauges 10-24 AWG experience full compatibility. Applications requiring 26-28 AWG wire support must verify alternative solutions.

Both components carry ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements. The stripping length variation (12 mm versus 10 mm) reflects design optimization within the CLIPLINE PTS series and does not affect functional substitution for standard installation practices.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 3213604 replace the 3031665 in all applications?

A: The 3213604 provides functional equivalence for applications using wire gauges 10-24 AWG. Applications requiring 26-28 AWG wire support must evaluate alternative components, as the 3213604 wire gauge range does not extend to these sizes.

Q: What is the significance of the series change from CLIPLINE STS to CLIPLINE PTS?

A: The series designation reflects internal Phoenix Contact product line organization. Both series maintain identical electrical ratings, mechanical dimensions, and termination characteristics relevant to component selection and substitution.

Q: Are there compliance differences between the two parts?

A: Both the 3031665 and 3213604 maintain ROHS3 compliance and REACH Unaffected status. No compliance barriers exist for substitution.

Q: How does the stripping length difference affect installation?

A: The 3213604 requires 12 mm stripping length compared to 10 mm for the 3031665. This variation reflects design optimization within the CLIPLINE PTS series. Standard installation practices accommodate this difference without affecting terminal block performance.

Q: Why is the 3031665 marked as Last Time Buy?

A: Last Time Buy status indicates Phoenix Contact has discontinued production of this part number. The 3213604 with Active status provides continued product availability and supply chain continuity.

Q: Are the electrical ratings identical between both parts?

A: Yes. Both components operate at 32 A IEC / 30 A UL current ratings and 800 V IEC / 600 V UL voltage ratings. Electrical performance is equivalent.
