Engineering Selection Recommendations

The Phoenix Contact 3031393 is a direct functional equivalent to the 3037355. Both components share identical electrical ratings, mechanical dimensions, and termination characteristics within the CLIPLINE ST series. The 3031393 is the recommended selection for new designs and ongoing production due to its active product status, ensuring sustained availability and manufacturer support. The 3031393 maintains RoHS3 compliance, meeting current regulatory requirements. Color differentiation (gray versus orange) is a cosmetic distinction and does not impact electrical performance or mechanical compatibility. For applications currently utilizing the obsolete 3037355, transition to the 3031393 presents no functional risk when electrical and mechanical parameters remain within specified limits.

Frequently Asked Questions (FAQ)

Q: Can the 3031393 directly replace the 3037355 in existing installations?

A: Yes. Both components are electrically and mechanically equivalent. They share identical current ratings (32 A IEC / 30 A UL), voltage ratings (800 V IEC / 600 V UL), wire gauge compatibility (10-28 AWG), and termination methodology. The only differences are product status and color designation.

Q: Does the color difference between orange (3037355) and gray (3031393) affect functionality?

A: No. Color is a cosmetic attribute and does not influence electrical performance, mechanical fit, or operational characteristics. Selection between colors is based on application requirements or system design preferences only.

Q: What is the significance of the product status change from obsolete to active?

A: Obsolete status indicates the manufacturer no longer produces the 3037355. The active status of the 3031393 ensures continued availability, technical support, and compliance with current manufacturing standards. For long-term supply chain reliability, the active part is preferred.

Q: Are there any compliance differences between the two parts?

A: Both parts are RoHS compliant. The 3031393 carries ROHS3 certification, representing the current regulatory standard. Both maintain UL94 V-0 flammability ratings and are suitable for applications requiring these certifications.

Q: What packaging options are available?

A: The 3037355 is supplied in standard packaging. The 3031393 is available in bulk packaging, which may affect procurement quantities and logistics considerations.

Q: Can these parts be used interchangeably in PCB designs or panel-mount applications?

A: Yes. Identical terminal width (6.2 mm), position count (3), and level configuration (1) ensure mechanical interchangeability in both PCB and panel-mount installations. No design modifications are required.
