Key Parameters

Substitute Part Grouping Explanation

The Phoenix Contact 2906231 qualifies as a direct substitute for the 2906233 based on the following critical parameters:

• Current Rating: Both rated for 4000 A
• Frequency Range: Both operate 16Hz ~ 1kHz
• Transformer Type: Both are non-invasive split core designs
• Mounting Configuration: Both mount on DIN rail
• Termination: Both use terminal block connections
• Physical Dimensions: Identical footprint (4.744" L x 0.244" W, height 4.350")
• Compliance: Both meet RoHS requirements

The primary distinction is product status: the 2906233 is obsolete while the 2906231 is active, with improved compliance documentation (ROHS3 and REACH Affected status).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2906231 is the direct active replacement for the obsolete 2906233. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in 4000 A current sensing applications. The 2906231 provides enhanced compliance documentation with ROHS3 certification and explicit REACH status declaration, meeting current regulatory requirements for industrial component procurement. Selection of the 2906231 eliminates obsolescence risk while maintaining full compatibility with existing DIN rail mounting infrastructure and terminal block connections.

Frequently Asked Questions (FAQ)

Q: Can the 2906231 directly replace the 2906233 in existing installations?

A: Yes. Both transformers share identical current ratings (4000 A), frequency response (16Hz ~ 1kHz), mounting type (DIN rail), physical dimensions, and termination style (terminal block). No circuit modifications or mechanical adjustments are required.

Q: What is the primary reason for substitution?

A: The 2906233 is classified as obsolete. The 2906231 is the active equivalent part from Phoenix Contact, ensuring continued availability and supply chain reliability.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant. The 2906231 carries ROHS3 certification and explicit REACH Affected status, providing more current regulatory documentation suitable for modern procurement requirements.

Q: Do the physical dimensions match exactly?

A: Yes. Both parts have identical dimensions: 4.744" L x 0.244" W (120.50mm x 6.20mm) with a maximum seated height of 4.350" (110.50mm). DIN rail mounting compatibility is identical.

Q: What is the moisture sensitivity level for both parts?

A: Both the 2906233 and 2906231 have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
