MSS4200 Equivalent & Substitute Parts

Part Overview

The MSS4200 is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a 4PDT (four-pole double-throw) switch rated for 300mA at 125V AC. This component features through-hole mounting with PC pin termination and epoxy sealed terminals. The MSS4200 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 MSS4200 is determined by electrical and mechanical parameter equivalence. The substitute part must maintain identical specifications across the following critical parameters: 4PDT circuit configuration, 300mA AC current rating, 125V AC voltage rating, shorting contact timing (MBB), on-on switch function, standard actuator type with 8.00mm length, copper alloy contact material with silver finish, through-hole mounting with PC pin termination, -20°C to 85°C operating temperature range, 2.00mm switch travel, 15,000 cycle mechanical and electrical life ratings, and 600gf operating force.

The substitute part 1825264-1 satisfies all these electrical and mechanical requirements and is manufactured by the same supplier (TE Connectivity ALCOSWITCH Switches) within the same MSS series family.

Engineering Selection Recommendations

The MSS4200 is obsolete and should be replaced with the 1825264-1 for new designs and ongoing production requirements. The 1825264-1 maintains complete electrical and mechanical equivalence across all specified parameters while offering active product status and ROHS3 compliance. The MSS4200 is RoHS non-compliant, whereas the 1825264-1 meets ROHS3 requirements, providing enhanced regulatory alignment for applications subject to RoHS directives.

Both parts share identical electrical ratings (300mA at 125V AC), circuit configuration (4PDT with shorting contact timing), mechanical specifications (8.00mm actuator length, 2.00mm travel, 600gf operating force), and lifecycle ratings (15,000 cycles for both mechanical and electrical life). The through-hole mounting with PC pin termination and epoxy sealed terminals are preserved in the substitute part, ensuring direct compatibility with existing PCB layouts and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 1825264-1 directly replace the MSS4200 in existing designs?

A: Yes. The 1825264-1 is electrically and mechanically equivalent to the MSS4200 across all specified parameters, including circuit configuration, current and voltage ratings, actuator dimensions, contact materials, and lifecycle ratings. Through-hole mounting and PC pin termination are identical, enabling direct PCB substitution.

Q: What is the primary difference between the MSS4200 and 1825264-1?

A: The MSS4200 is obsolete with RoHS non-compliant status, while the 1825264-1 is an active product with ROHS3 compliance. All electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: The MSS4200 is supplied in standard packaging, while the 1825264-1 is supplied in bulk packaging. This difference does not affect component functionality or compatibility.

Q: What are the critical parameters for substitution of 4PDT slide switches?

A: Critical parameters include circuit configuration (4PDT), current rating (300mA AC), voltage rating (125V AC), contact timing (shorting/MBB), switch function (on-on), actuator type and length (standard, 8.00mm), contact material and finish (copper alloy with silver), mounting type (through hole), termination style (PC pin), operating temperature range (-20°C to 85°C), switch travel (2.00mm), and lifecycle ratings (15,000 cycles mechanical and electrical).

Q: Is the 1825264-1 suitable for applications requiring RoHS compliance?

A: Yes. The 1825264-1 is ROHS3 compliant, making it suitable for applications subject to RoHS directives. The MSS4200 is RoHS non-compliant and should not be used in RoHS-regulated applications.

Q: Do both parts have the same operating temperature range?

A: Yes. Both the MSS4200 and 1825264-1 operate across the identical temperature range of -20°C to 85°C.

Q: Are the contact materials and finishes identical?

A: Yes. Both parts feature copper alloy contact material with silver finish, ensuring equivalent electrical performance and contact reliability.
