Key Parameters

Substitute Part Grouping Explanation

The MHS233 can be substituted with part number 1825289-8 from TE Connectivity ALCOSWITCH Switches based on the following matching parameters:

• Circuit configuration: Both are DP3T switches
• Current rating: Both support 300mA
• Switch function: Both provide On-On-On operation
• Actuator type and length: Both feature standard actuators at 4.50mm
• Mounting and termination: Both use through-hole mounting with PC pin termination
• Contact material and finish: Both use silver-finished contacts
• Operating temperature range: Both operate from -20°C to 85°C
• Compliance: Both are ROHS3 compliant and REACH unaffected

The primary difference is voltage rating: MHS233 is rated for 30V DC, while 1825289-8 is rated for 125V AC. This difference allows 1825289-8 to function in the MHS233 application, as the substitute part exceeds the original voltage specification.

Parameter Comparison

Engineering Selection Recommendations

The 1825289-8 is a direct functional substitute for the obsolete MHS233. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment. The substitute part is currently in active production status with higher inventory availability (2211 pcs vs. 782 pcs), providing supply chain stability.

The 1825289-8 offers enhanced electrical life (15,000 cycles vs. 10,000 cycles) and higher mechanical life rating (15,000 cycles), making it suitable for applications requiring extended operational durability. The voltage rating increase from 30V DC to 125V AC provides additional design margin for applications operating within the original specification.

Frequently Asked Questions (FAQ)

Q: Can 1825289-8 directly replace MHS233 in existing designs?

A: Yes. Both parts share identical circuit configuration (DP3T), current rating (300mA), switch function (On-On-On), actuator specifications (4.50mm standard type), mounting method (through-hole), and termination style (PC pin). Physical and electrical compatibility is maintained.

Q: What is the significance of the voltage rating difference?

A: The MHS233 is rated for 30V DC operation, while 1825289-8 is rated for 125V AC. In DC applications at 30V or below, the 1825289-8 operates within safe margins. The higher voltage rating of the substitute does not create compatibility issues in lower-voltage applications.

Q: Are there packaging differences between these parts?

A: MHS233 is packaged as individual units (packaging not specified), while 1825289-8 is supplied in bulk packaging. Both use identical through-hole PC pin termination suitable for PCB assembly.

Q: How do the electrical life ratings compare?

A: MHS233 is rated for 10,000 electrical cycles, while 1825289-8 is rated for 15,000 electrical cycles. The substitute part provides 50% additional cycle life, beneficial for high-frequency switching applications.

Q: Are both parts compliant with current regulations?

A: Yes. Both MHS233 and 1825289-8 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component procurement.
