Engineering Selection Recommendations

All listed substitute parts meet the electrical and mechanical requirements for direct replacement of the SCHURTER 4430.2908. Selection among these equivalents should be based on:

Regulatory Certification: Parts 4430.2908, 4430.0572, 4430.1067, 4430.1068, and 4430.161 carry documented approval agency certifications (CSA C22.2 No 235, EN 60934, GB 17701, IEC 60934, UL1077). These parts are preferred for applications requiring specific regional compliance documentation.

Moisture Sensitivity: Parts with "Not Applicable" MSL designation (4430.2908, 4430.0572, 4430.1067, 4430.1068, 4430.161) are suitable for standard storage and handling conditions. Parts with "Vendor Undefined" MSL (4430.0038, 4430.0988, 4430.1629, 4430.1789) require verification of storage requirements with the supplier.

Inventory Availability: All parts maintain adequate stock levels ranging from 673 to 1098 units, supporting production and replacement requirements.

Frequently Asked Questions (FAQ)

Q: Can any of these substitute parts replace the SCHURTER 4430.2908 in my application?

A: Yes. All listed parts are parametric equivalents with identical current rating (20A), voltage ratings (240V AC / 60V DC), mounting configuration (panel mount), actuator type (rocker), and pole count (2). They are direct functional replacements within the TA45 series.

Q: What is the difference between parts with and without approval agency certifications?

A: Parts 4430.2908, 4430.0572, 4430.1067, 4430.1068, and 4430.161 carry documented certifications from CSA, EN, GB, IEC, and UL standards bodies. These certifications provide third-party validation of compliance. Parts without listed certifications may still meet equivalent standards but lack documented approval agency validation. Selection depends on your application's regulatory requirements.

Q: Are there any differences in moisture sensitivity between substitute parts?

A: Parts designated "Not Applicable" for MSL (4430.2908, 4430.0572, 4430.1067, 4430.1068, 4430.161) do not require special moisture-controlled storage. Parts with "Vendor Undefined" MSL (4430.0038, 4430.0988, 4430.1629, 4430.1789) should be confirmed with the supplier regarding storage conditions, though this does not affect electrical or mechanical compatibility.

Q: Do all substitute parts use the same packaging?

A: Yes. All parts are supplied in Bulk packaging, consistent with the main part number 4430.2908.

Q: Which substitute part has the highest inventory availability?

A: Part 4430.1629 has the highest inventory at 1098 units, followed by 4430.0988 at 1097 units. Both are suitable for high-volume production requirements.
