MSS2220 Equivalent & Substitute Parts

Part Overview

The MSS2220 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Double Pole Double Throw (DPDT) switch with a 300mA AC current rating at 125V. This component features a through-hole mounting design with epoxy sealed terminals and polyoxymethylene actuator material. The MSS2220 is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure ongoing component availability for production and repair applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS2220 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Circuit configuration must be DPDT
• Current rating must support minimum 300mA AC
• Voltage rating must support minimum 125V AC
• Contact timing must be Shorting (MBB)
• Switch function must be On-On

Mechanical Compatibility Criteria:

• Mounting type must be Through Hole
• Termination style must be PC Pin
• Contact material must be Copper Alloy with Silver finish
• Operating temperature range must encompass -20°C to 85°C
• Mechanical and electrical life must meet or exceed 15,000 cycles
• Operating force must be 600gf
• Switch travel must be 2.00mm

The substitute part 1825261-1 satisfies all electrical and mechanical compatibility requirements, with the distinction that it maintains active product status and RoHS3 compliance, addressing the obsolescence of the original MSS2220.

Parameter Comparison

Engineering Selection Recommendations

The part 1825261-1 is the direct functional equivalent to the MSS2220. Selection of 1825261-1 is supported by the following engineering factors:

Product Status: The MSS2220 is classified as obsolete, while 1825261-1 maintains active product status. Active status ensures continued manufacturing support, quality assurance, and component availability.

Compliance Certifications: The 1825261-1 carries RoHS3 compliance certification, meeting current regulatory requirements for electronic component manufacturing. This compliance status addresses environmental and hazardous substance restrictions applicable to modern production environments.

Electrical and Mechanical Equivalence: All critical electrical parameters (circuit configuration, current rating, voltage rating, contact timing, and switch function) are identical between the two parts. All mechanical parameters (mounting type, termination style, contact material and finish, operating temperature range, mechanical and electrical life, operating force, and switch travel) are identical.

Actuator Dimension Variance: The 1825261-1 features an actuator length of 2.30mm compared to the MSS2220 actuator length of 5.00mm. This dimensional difference requires mechanical design verification to ensure compatibility with existing actuator access and clearance requirements in the application.

Frequently Asked Questions (FAQ)

Q: Can the 1825261-1 directly replace the MSS2220 in all applications?

A: The 1825261-1 is electrically and mechanically equivalent to the MSS2220 across all specified parameters. However, the actuator length differs (2.30mm versus 5.00mm). Mechanical design verification is required to confirm that the shorter actuator length is compatible with the application's actuator access and clearance requirements.

Q: What is the significance of the MSS2220 being classified as obsolete?

A: Obsolete status indicates that the MSS2220 is no longer in active production. This classification necessitates transition to an active equivalent part to ensure continued component availability, manufacturing support, and quality assurance for ongoing production and field repair applications.

Q: Does the 1825261-1 meet current regulatory requirements?

A: Yes. The 1825261-1 carries RoHS3 compliance certification, meeting current environmental and hazardous substance restrictions. Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications.

Q: Are the electrical specifications identical between the MSS2220 and 1825261-1?

A: Yes. Both parts are DPDT switches with 300mA AC current rating at 125V, Shorting (MBB) contact timing, and On-On switch function. Contact material (Copper Alloy), contact finish (Silver), and all electrical life parameters are identical.

Q: Are the mechanical specifications identical between the MSS2220 and 1825261-1?

A: All mechanical specifications are identical except for actuator length. Both parts feature through-hole mounting, PC pin termination, 15,000 cycle mechanical and electrical life, 600gf operating force, 2.00mm switch travel, and -20°C to 85°C operating temperature range. The 1825261-1 has a 2.30mm actuator length compared to the MSS2220's 5.00mm actuator length.

Q: What packaging differences exist between these parts?

A: The MSS2220 is supplied in standard packaging, while the 1825261-1 is supplied in bulk packaging. Packaging selection should be based on procurement volume and inventory management requirements.

Q: Are both parts from the same manufacturer?

A: Yes. Both the MSS2220 and 1825261-1 are manufactured by TE Connectivity ALCOSWITCH Switches and share the same base product series (MSS and 1825261 respectively).
