SL330 Equivalent & Substitute Parts

Part Overview

The SL330 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole triple-throw (SP3T) switch with non-shorting contact timing. The switch is rated for 250mA AC at 125V and 150mA DC at 12V, featuring through-hole mounting with PC pin termination and epoxy sealed terminals. The SL330 is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure ongoing component availability for production and repair applications.

• 250mA AC current rating at 125V
• 150mA DC current rating at 12V
• On-On-On switch function

Mechanical Equivalence:

• Through-hole mounting with PC pin termination
• 14.00mm actuator length
• 4.00mm switch travel
• Standard actuator type with steel, zinc-plated construction
• Copper alloy contacts with silver finish
• Epoxy sealed terminals

Environmental Compatibility:

• Operating temperature range of -10°C to 60°C
• Mechanical life rating of 10,000 cycles
• Electrical life rating of 6,000 cycles
• Operating force range of 100 to 300gf

Engineering Selection Recommendations

The part number 1825073-2 is the direct active equivalent for the obsolete SL330. All electrical and mechanical parameters are identical across both components. The 1825073-2 maintains the same circuit configuration, current and voltage ratings, physical dimensions, contact materials, and environmental operating specifications as the SL330.

The primary distinction between the two parts is product status: the SL330 is classified as obsolete, while the 1825073-2 is actively manufactured and supported. Both parts share identical export control classifications (ECCN: EAR99) and tariff codes (HTSUS: 8536.50.9050).

For new designs and ongoing production requirements, the 1825073-2 is the appropriate selection. For legacy system maintenance where the SL330 is currently installed, the 1825073-2 provides direct functional and physical compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 1825073-2 be used as a direct replacement for the SL330 in existing designs?
