The substitute part 1825222-3 maintains full equivalence across all critical electrical, mechanical, and environmental parameters. The primary distinction is product status: the substitute is active and available, whereas the original part is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The TT13D2T is classified as obsolete and no longer in active production. The substitute part 1825222-3 is the manufacturer-recommended equivalent and is currently active in the product portfolio.

Selection Basis:

1. Electrical Equivalence: The substitute part maintains identical electrical specifications across all parameters: SPDT circuit, On-On function, 3A current rating, and 125V AC / 28V DC voltage ratings.

2. Mechanical Compatibility: Panel mount configuration, actuator dimensions, termination style, and panel cutout specifications are identical, ensuring direct mechanical interchangeability without design modification.

3. Environmental Compliance: Both parts are ROHS3 compliant. The substitute part carries REACH Affected status, indicating full regulatory compliance documentation, whereas the original part status is vendor undefined.

4. Product Lifecycle: The substitute part is active and available with established supply chain support. The original part is obsolete and subject to inventory depletion.

5. Enhanced Performance: The substitute part provides extended electrical life (80,000 cycles versus 20,000 cycles), offering improved reliability and longevity in field applications.

For new designs and production applications, the 1825222-3 is the appropriate selection. For field replacements of existing TT13D2T installations, the 1825222-3 provides direct functional and mechanical substitution.
