Substitute Part Grouping Explanation

Substitution of the obsolete 1825160-1 is based on electrical and mechanical compatibility within the SPDT slide switch category. The substitute part 1825256-1 maintains functional equivalence through identical electrical specifications: SPDT circuit configuration, 300mA AC current rating, and 125V AC voltage rating. Both parts feature shorting contact timing (MBB), On-On switch function, through-hole right-angle mounting, and PC pin termination with epoxy sealed terminals.

The 1825256-1 qualifies as a direct substitute based on the following key parameters:

• Identical circuit configuration (SPDT)
• Identical current rating (300mA AC)
• Identical voltage rating (125V AC)
• Identical contact timing (Shorting/MBB)
• Identical switch function (On-On)
• Identical mounting type (Through Hole, Right Angle)
• Identical termination style (PC Pin)
• Identical contact material and finish (Copper Alloy with Silver finish)
• Identical actuator material (Polyoxymethylene/Acetal)

The 1825256-1 is part of the MHS series and carries Active product status, providing long-term availability and support compared to the obsolete 1825160-1.

Parameter Comparison

Engineering Selection Recommendations

The 1825256-1 serves as the direct electrical and functional substitute for the obsolete 1825160-1. Both parts maintain identical electrical specifications (SPDT, 300mA AC, 125V AC) and identical mechanical mounting characteristics (through-hole, right-angle, PC pin termination).

The 1825256-1 provides enhanced performance characteristics compared to the 1825160-1:

• Extended mechanical life rating (15,000 cycles versus 10,000 cycles)
• Wider operating temperature range (-20°C to 85°C versus -10°C to 60°C)
• ROHS3 compliance certification
• Active product status ensuring continued availability and supply chain support

Physical differences exist in actuator length (4.50mm versus 4.00mm), switch travel (4.00mm versus 2.50mm), and operating force (600gf versus 250gf). These dimensional and force variations require mechanical design review to confirm fit within the target application's physical constraints and user interface requirements.

The 1825256-1 is suitable for applications requiring the same electrical switching performance as the 1825160-1 where mechanical envelope and actuation force compatibility can be accommodated.

Frequently Asked Questions (FAQ)

Q: Can the 1825256-1 directly replace the 1825160-1 in all applications?

A: The 1825256-1 provides electrical and functional equivalence for SPDT switching at 300mA and 125V AC. However, mechanical differences in actuator length, switch travel, and operating force require verification that the substitute part fits the physical mounting space and meets the user interface actuation requirements of the original design.

Q: What are the key electrical parameters that make these parts equivalent?

A: Both parts share identical SPDT circuit configuration, 300mA AC current rating, 125V AC voltage rating, shorting contact timing (MBB), On-On switch function, and PC pin termination with epoxy sealed terminals. These parameters define electrical and functional equivalence.

Q: How do the mechanical differences affect substitution?

A: The 1825256-1 has a longer actuator (4.50mm versus 4.00mm), greater switch travel (4.00mm versus 2.50mm), and higher operating force (600gf versus 250gf). These differences may impact panel cutout dimensions, actuator clearance, and the force required to operate the switch. Physical design review is necessary to confirm compatibility with the target application.

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

A: The 1825160-1 is classified as obsolete, indicating discontinued manufacturing and limited long-term availability. The 1825256-1 carries Active status, ensuring ongoing production, supply chain availability, and manufacturer support for the foreseeable future.

Q: Does the 1825256-1 offer any performance advantages?

A: The 1825256-1 provides extended mechanical life (15,000 cycles versus 10,000 cycles), a wider operating temperature range (-20°C to 85°C versus -10°C to 60°C), and ROHS3 compliance certification. These enhancements support applications with more demanding environmental or cycle-life requirements.

Q: Are there packaging differences between these parts?

A: The 1825160-1 packaging is listed as unspecified in the provided data. The 1825256-1 is supplied in Bulk packaging. Packaging format should be confirmed with the supplier based on production volume and handling requirements.

Q: What compliance certifications apply to the 1825256-1?

A: The 1825256-1 is ROHS3 compliant. Both parts carry EAR99 export classification and share the same HTSUS code (8536.50.9050). Moisture Sensitivity Level (MSL) is Not Applicable for both parts.
