The substitute part 1825255-1 maintains full electrical and mechanical equivalence while offering alternative actuator design and packaging options.

Parameter Comparison

Engineering Selection Recommendations

Part 1825255-3 Selection Criteria:

• Applications requiring baton-style actuators with extended 10.00mm length
• Designs utilizing aluminum actuator material for specific mechanical properties
• Tape & Box packaging for automated assembly processes
• Environments where RoHS applicability is not a constraint

Part 1825255-1 Selection Criteria:

• Applications compatible with standard actuator form factor and 4.50mm length
• Designs utilizing polyoxymethylene (acetal) actuator material
• Bulk packaging for manual assembly or stock management
• Applications requiring ROHS3 compliance certification
• Inventory availability of 999 units in stock

Both parts maintain identical electrical performance (300mA at 125V AC SPDT configuration) and mechanical durability (15,000 cycle life). Selection between these variants depends on actuator geometry requirements, packaging format preferences, and regulatory compliance needs specific to the application.

Frequently Asked Questions (FAQ)

Q: Can 1825255-1 be used as a direct replacement for 1825255-3 in existing designs?

A: Electrical and mechanical substitution is valid. However, the actuator length differs (4.50mm vs. 10.00mm) and actuator material differs (Acetal vs. Aluminum). Physical space constraints and mechanical interface requirements must be evaluated for the specific application.

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

A: There are no electrical differences. Both parts are SPDT switches rated for 300mA at 125V AC with identical contact timing (Shorting/MBB), contact material (Copper Alloy with Silver finish), and electrical life (15,000 cycles).

Q: Does the actuator material change affect performance?

A: The actuator material change from Aluminum (1825255-3) to Polyoxymethylene/Acetal (1825255-1) does not affect electrical performance or switching characteristics. Operating force remains 600gf for both variants. Material selection impacts mechanical properties and environmental resistance specific to the actuator.

Q: What is the significance of the packaging difference?

A: 1825255-3 is supplied in Tape & Box (TB) format, suitable for automated pick-and-place assembly. 1825255-1 is supplied in Bulk packaging, suitable for manual assembly or alternative handling processes. Packaging does not affect component performance.

Q: Are there compliance differences between these parts?

A: 1825255-1 carries ROHS3 compliance certification. 1825255-3 has RoHS status listed as "Not applicable." Applications requiring RoHS3 compliance should specify 1825255-1.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -20°C to 85°C. This identical temperature range ensures thermal compatibility in equivalent applications.

Q: How do the actuator lengths affect PCB layout?

A: 1825255-3 features a 10.00mm baton actuator, while 1825255-1 features a 4.50mm standard actuator. PCB clearance and user interface accessibility must accommodate the selected actuator length. Panel cutout dimensions and surrounding component placement require verification for each variant.

Q: Are the mechanical life ratings identical?

A: Yes. Both parts are rated for 15,000 mechanical cycles and 15,000 electrical cycles, providing equivalent durability and expected service life.
