Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2281733 has one identified equivalent substitute: part number 2315146. This substitution is valid based on the following matching parameters:

• Positions / Poles: Both parts provide 37-position connectivity
• Process Side Connection: Both use terminal blocks with screw connection
• Control Side Connection: Both interface to D-Sub male connectors
• Wire Gauge: Both accept 12-24 AWG conductors
• Voltage Rating: Both are rated for 125V operation
• Control Side Cable Retainer: Both feature jackscrew socket retention

The 2315146 represents an active product within the VARIOFACE series evolution, specifically the VIP variant, providing functional continuity for applications currently using the obsolete 2281733.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 2315146 directly replace the 2281733 in existing installations?

A: Yes. Both parts provide identical 37-position D-Sub male to screw terminal block interface functionality. The 2315146 maintains the same electrical ratings (125V, 12-24 AWG) and connection types required for direct substitution.

Q: What are the physical differences between these parts?

A: The 2315146 has reduced overall dimensions compared to the 2281733. The 2315146 measures 2.862" × 2.717" versus the 2281733 at 3.110" × 3.031". This dimensional reduction reflects design optimization within the VARIOFACE series evolution from FLKMS to VIP variants.

Q: Is there a current rating difference between these parts?

A: Yes. The 2281733 is rated at 2.5 A per contact, while the 2315146 is rated at 2 A per contact. Applications requiring the full 2.5 A per contact capacity must verify that the 2315146's 2 A rating is sufficient for their specific current requirements.

Q: Are both parts RoHS compliant?

A: Yes. The 2281733 is RoHS Compliant, and the 2315146 meets the current ROHS3 standard, confirming environmental compliance for both parts.

Q: What is the packaging difference?

A: The 2281733 packaging is not specified in available documentation. The 2315146 is supplied in box packaging, which is standard for active production inventory.
