MSS4300 Equivalent & Substitute Parts

Part Overview

The MSS4300 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a 4-pole 3-throw (4P3T) through-hole component rated for 300mA AC at 125V. This switch features shorting contact timing (MBB), an acetal actuator with 5.50mm length, and silver-plated copper alloy contacts. The MSS4300 is classified as obsolete, making identification of equivalent active alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS4300 is determined by electrical and mechanical parameter equivalence within the TE Connectivity ALCOSWITCH Switches product family. The substitute part must maintain identical specifications across the following critical parameters:

• Circuit configuration (4P3T)
• Current rating (300mA AC)
• Voltage rating (125V AC)
• Contact timing behavior (Shorting/MBB)
• Switch function (On-On-On)
• Mounting type (Through Hole)
• Termination style (PC Pin)
• Actuator length (5.50mm)
• Contact material and finish (Copper Alloy with Silver plating)
• Operating temperature range (-20°C to 85°C)
• Mechanical and electrical life (15,000 Cycles)
• Operating force (600gf)

The substitute part 1825267-1 satisfies all these parameters and represents an active product status alternative to the obsolete MSS4300.

Parameter Comparison

Engineering Selection Recommendations

The part 1825267-1 is a direct functional equivalent to the obsolete MSS4300. Both components are manufactured by TE Connectivity ALCOSWITCH Switches and share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product status: MSS4300 is obsolete while 1825267-1 is active.

Selection of 1825267-1 is supported by the following factors:

• Complete parameter equivalence with MSS4300 across circuit configuration, current and voltage ratings, contact timing, and mechanical characteristics
• Active product status ensuring ongoing availability and manufacturing support
• RoHS3 compliance certification for 1825267-1, providing regulatory alignment for modern applications
• Identical ECCN and HTSUS classifications, confirming trade and export compliance consistency
• Through-hole mounting and PC pin termination compatibility with existing PCB designs specified for MSS4300

Frequently Asked Questions (FAQ)

Q: Can 1825267-1 be used as a direct replacement for MSS4300 in existing designs?

A: Yes. The 1825267-1 is electrically and mechanically equivalent to MSS4300 across all specified parameters, including circuit configuration (4P3T), current rating (300mA AC), voltage rating (125V AC), actuator dimensions (5.50mm length), contact materials, and operating characteristics.
