Key Parameters

Substitute Part Grouping Explanation

The TE Connectivity ALCOSWITCH 1825255-1 qualifies as a substitute based on the following matching parameters:

• Circuit configuration: SPDT (identical)
• Current rating: 300mA (identical)
• Mounting type: Through hole (identical)
• Termination style: PC pin (identical)
• Actuator length: 4.50mm (identical)
• Switch travel: 4.00mm (identical)
• Operating temperature range: -20°C to 85°C (identical)
• Contact finish: Silver (identical)
• Features: Epoxy sealed terminals (identical)
• RoHS compliance: ROHS3 compliant (identical)

The primary difference is voltage rating: the MHS122 operates at 30V DC, while the 1825255-1 operates at 125V AC. The 1825255-1 also demonstrates superior mechanical and electrical life ratings (15,000 cycles versus 10,000 cycles) and higher operating force (600gf versus 250gf).

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity 1825255-1 is an active product with ROHS3 compliance and established supply chain availability. Selection of this substitute requires verification that the application voltage specification can accommodate 125V AC operation. The substitute provides extended mechanical and electrical life cycles, supporting long-term reliability in production environments. Both components share identical physical form factors and termination methods, enabling direct mechanical and electrical integration without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the 1825255-1 directly replace the MHS122 in all applications?

A: Direct replacement is possible only in applications where the circuit voltage specification does not exceed 125V AC. The MHS122 is rated for 30V DC operation, while the 1825255-1 is rated for 125V AC. Verify your application voltage requirements before substitution.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both components share identical actuator length (4.50mm), switch travel (4.00mm), and through-hole PC pin termination, enabling direct mechanical substitution without PCB modification.

Q: What is the significance of the product status difference?

A: The MHS122 is obsolete, meaning APEM Inc. no longer manufactures or supports this component. The 1825255-1 is active, ensuring ongoing availability, technical support, and supply chain continuity for new designs and production runs.

Q: How do the electrical life ratings compare?

A: The MHS122 is rated for 10,000 electrical cycles, while the 1825255-1 is rated for 15,000 electrical cycles. The substitute provides 50% extended cycle life, supporting applications requiring higher switching frequency or longer operational lifespan.

Q: Are both components RoHS compliant?

A: Yes. Both the MHS122 and 1825255-1 are ROHS3 compliant, meeting environmental and regulatory requirements for electronic component manufacturing and distribution.
