Parameter Comparison

Engineering Selection Recommendations

The 1182G18 serves as the direct substitute for the obsolete 182G18. Both components maintain identical electrical specifications across all critical parameters: 225VA power rating, dual primary and secondary winding configurations, 117V/234V primary voltage support, 18V/36V secondary voltage capability, and 4000Vrms isolation voltage.

The 1182G18 offers the advantage of active product status, ensuring continued availability and supply chain reliability. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the 1182G18 directly replace the 182G18 in existing applications?

A: Yes. The 1182G18 provides complete electrical and functional equivalence. All voltage ratings, current capacities, winding configurations, isolation specifications, and mounting characteristics are identical.

Q: What are the key differences between these two parts?

A: The primary differences are product status and packaging. The 182G18 is obsolete, while the 1182G18 is active. The 1182G18 is supplied in box packaging, whereas the 182G18 uses standard packaging. Electrically and mechanically, both parts are equivalent.

Q: Are there any physical dimension variations that would affect installation?

A: Both transformers are chassis mount toroidal units with wire lead termination. The 1182G18 has a diameter of 114.30mm and height of 47.75mm. The 182G18 height is specified as 48.26mm maximum. These minor dimensional differences do not affect compatibility in standard chassis mount applications.

Q: Do both parts meet current compliance standards?

A: Yes. Both the 182G18 and 1182G18 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use.

Q: Which part should be selected for new designs?

A: The 1182G18 should be selected for new designs due to its active product status and assured long-term availability.
