MSS4350RG Equivalent & Substitute Parts

Part Overview

The MSS4350RG is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a 4-pole 3-throw (4P3T) through-hole, right-angle mounted component. This switch is rated for 0.4VA at 20V AC/DC operation with gold-plated copper alloy contacts and epoxy-sealed terminals. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSS4350RG is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications for circuit configuration (4P3T), contact timing (shorting MBB), current and voltage ratings (0.4VA at 20V AC/DC), mounting configuration (through-hole right-angle), termination style (PC pin), contact material and finish (copper alloy with gold plating), actuator dimensions (14.00mm length, 2.00mm travel), operating force (600gf), and lifecycle ratings (15,000 mechanical and electrical cycles). The operating temperature range (-20°C to 85°C) and epoxy-sealed terminal feature must also be maintained. Substitution is valid only when all parameters match exactly across both parts.

Parameter Comparison

Engineering Selection Recommendations

The MSS4350RG and 1825270-2 are electrically and mechanically equivalent across all functional parameters. Both parts are classified as obsolete and manufactured by TE Connectivity ALCOSWITCH Switches with identical circuit configurations, electrical ratings, mechanical specifications, and physical dimensions.

A key distinction exists in regulatory compliance status. The 1825270-2 is ROHS3 compliant, whereas the MSS4350RG is RoHS non-compliant. For applications subject to RoHS directives or requiring compliance with current environmental regulations, the 1825270-2 is the appropriate selection. The MSS4350RG remains suitable for applications where RoHS compliance is not mandated.

Both parts share identical ECCN (EAR99) and HTSUS (8536.50.9050) classifications, indicating equivalent export control and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 1825270-2 be used as a direct replacement for the MSS4350RG in existing designs?

A: Yes. The 1825270-2 is electrically and mechanically equivalent to the MSS4350RG. All functional parameters, including circuit configuration, voltage and current ratings, mounting type, termination style, and lifecycle specifications, are identical. Direct substitution is valid from a technical standpoint.

Q: What is the difference between these two parts?

A: The primary difference is regulatory compliance status. The 1825270-2 is ROHS3 compliant, while the MSS4350RG is RoHS non-compliant. Both parts are obsolete and share identical electrical and mechanical specifications.

Q: Are there any physical dimension differences between MSS4350RG and 1825270-2?

A: No. Both parts have identical actuator length (14.00mm), switch travel (2.00mm), and mounting configuration (through-hole, right-angle). Physical compatibility is maintained.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, the 1825270-2 is the appropriate choice. Both parts are obsolete, so long-term availability should be evaluated independently.

Q: Are the contact materials and finishes the same?

A: Yes. Both parts use copper alloy contacts with gold plating, ensuring identical electrical performance and contact reliability.

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

A: Yes. Both the MSS4350RG and 1825270-2 operate across the temperature range of -20°C to 85°C.

Q: What is the mechanical and electrical life expectancy for both parts?

A: Both parts are rated for 15,000 mechanical cycles and 15,000 electrical cycles, providing identical lifecycle performance.
