MSS2250 Equivalent & Substitute Parts

Part Overview

The MSS2250 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 through-hole mounting with PC pin termination and is designed for applications requiring reliable switching with epoxy sealed terminals.

The MSS2250 is classified as obsolete. Locating active production alternatives is necessary to ensure continued component availability, supply chain reliability, and access to current manufacturing compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS2250 is based on electrical and mechanical parameter equivalence. The substitute part 1825263-1 maintains identical specifications across all critical switching parameters: DPDT circuit configuration, 300mA AC current rating, 125V AC voltage rating, shorting contact timing, on-on switch function, 11.00mm actuator length, through-hole mounting, PC pin termination, copper alloy contacts with silver finish, and identical mechanical and electrical life ratings of 15,000 cycles.

The key parameters determining substitution eligibility are:

• Circuit configuration (DPDT)
• Current and voltage ratings (300mA AC / 125V AC)
• Contact timing and switch function (Shorting MBB / On-On)
• Physical dimensions (11.00mm actuator length, 2.00mm switch travel)
• Mounting and termination compatibility (Through Hole / PC Pin)
• Contact material and finish specifications
• Operating temperature range (-20°C to 85°C)
• Mechanical and electrical life (15,000 cycles each)

Parameter Comparison

Engineering Selection Recommendations

The part 1825263-1 is a direct functional equivalent to the MSS2250 across all electrical and mechanical parameters. Both components are manufactured by TE Connectivity ALCOSWITCH Switches within the MSS series and share identical switching characteristics, ratings, and physical specifications.

The primary distinction between these parts is product status and regulatory compliance. The MSS2250 is obsolete and carries RoHS non-compliant status. The 1825263-1 is an active production component with ROHS3 compliance certification, making it the appropriate selection for new designs and ongoing production requirements.

For applications where the MSS2250 is currently deployed, the 1825263-1 provides direct substitution without circuit redesign or board layout modification. The identical actuator length, switch travel, mounting configuration, and termination style ensure mechanical and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can 1825263-1 directly replace MSS2250 in existing circuit designs?

A: Yes. The 1825263-1 maintains identical electrical ratings (300mA AC at 125V), circuit configuration (DPDT), contact timing (Shorting MBB), and physical dimensions (11.00mm actuator, 2.00mm travel). Through-hole mounting and PC pin termination are identical. No circuit modification is required.

Q: What is the difference in packaging between MSS2250 and 1825263-1?

A: The MSS2250 is supplied in standard packaging, while 1825263-1 is supplied in bulk packaging. Both components are identical in form, fit, and function. Packaging selection depends on procurement volume and inventory management requirements.

Q: Why is the MSS2250 classified as obsolete?

A: The MSS2250 has been discontinued by TE Connectivity ALCOSWITCH Switches. The 1825263-1 is the active production equivalent and is the recommended component for new applications and ongoing supply.

Q: Does the RoHS3 compliance of 1825263-1 affect compatibility with MSS2250 designs?

A: No. RoHS3 compliance indicates adherence to current environmental and material restriction standards. The 1825263-1 is electrically and mechanically identical to the MSS2250 and functions identically in all applications. RoHS3 compliance is an advantage for regulatory requirements and environmental standards.

Q: Are the mechanical life and electrical life ratings identical?

A: Yes. Both the MSS2250 and 1825263-1 are rated for 15,000 mechanical cycles and 15,000 electrical cycles, with identical operating force of 600gf and operating temperature range of -20°C to 85°C.

Q: Can 1825263-1 be used in applications originally designed for MSS2250?

A: Yes. The 1825263-1 is a direct substitute. All electrical parameters, mechanical dimensions, mounting specifications, and contact characteristics are identical. No design changes are necessary.
