MSSA2350R Equivalent & Substitute Parts

Part Overview

The MSSA2350R is a slide switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a DP3T (Double Pole Triple Throw) through-hole, right-angle mounted component. This switch is rated for 300mA AC at 125V and features epoxy sealed terminals with a mechanical and electrical life of 15,000 cycles. The MSSA2350R is classified as obsolete, making identification of equivalent substitute parts necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MSSA2350R is based on electrical and mechanical parameter equivalence. The primary substitute part 1825199-1 maintains identical electrical specifications: DP3T circuit configuration, 300mA AC current rating, and 125V AC voltage rating. Both parts feature the same switch function (On-On-On), contact timing (Shorting MBB), mounting type (Through Hole, Right Angle), and termination style (PC Pin). Operating temperature range, mechanical life, and electrical life specifications are identical across both parts.

The key parameters determining substitution eligibility are:

• Circuit configuration (DP3T)
• Current and voltage ratings (300mA AC / 125V AC)
• Switch function and contact timing
• Mounting and termination compatibility
• Operating temperature range
• Mechanical and electrical life ratings

Parameter Comparison

Engineering Selection Recommendations

The MSSA2350R is an obsolete product, and the 1825199-1 serves as the active equivalent substitute. Both parts are manufactured by TE Connectivity ALCOSWITCH Switches and maintain identical electrical and mechanical specifications for circuit configuration, current rating, voltage rating, switch function, and operating temperature range.

The 1825199-1 offers the advantage of active product status, ensuring ongoing availability and manufacturer support. Additionally, the 1825199-1 is ROHS3 compliant, whereas the MSSA2350R is non-compliant. For applications requiring RoHS compliance, the 1825199-1 is the appropriate selection.

Minor differences exist in actuator length (9.02mm versus 8.89mm), actuator material (Polyester versus Polyamide PA66), and operating force (470gf versus 600gf). These differences do not affect electrical performance or circuit compatibility. Mechanical clearance and actuation force requirements must be evaluated within the specific application context.

Frequently Asked Questions (FAQ)

Q: Can the 1825199-1 directly replace the MSSA2350R in existing designs?

A: The 1825199-1 is electrically and functionally equivalent to the MSSA2350R. Both parts share identical circuit configuration (DP3T), current rating (300mA AC), voltage rating (125V AC), switch function (On-On-On), and operating temperature range (-20°C to 85°C). Physical mounting and termination are compatible. Mechanical clearance and actuator force differences (actuator length 8.89mm versus 9.02mm; operating force 600gf versus 470gf) must be evaluated for the specific application.

Q: What is the primary reason for substituting the MSSA2350R?

A: The MSSA2350R is classified as obsolete. The 1825199-1 is the active equivalent part from the same manufacturer, ensuring continued availability and manufacturer support.

Q: Are there compliance differences between these parts?

A: Yes. The MSSA2350R is RoHS non-compliant, while the 1825199-1 is ROHS3 compliant. For applications subject to RoHS requirements, the 1825199-1 is the required selection.

Q: What are the packaging differences?

A: The MSSA2350R is supplied in bulk packaging, while the 1825199-1 is supplied in tray packaging. This difference affects handling and storage but does not impact electrical or mechanical performance.

Q: Do the actuator material differences affect performance?

A: The MSSA2350R uses polyester actuator material, while the 1825199-1 uses polyamide (PA66) nylon 6/6. Both materials are suitable for the specified operating temperature range (-20°C to 85°C). The actuator material change does not affect electrical performance or circuit compatibility.

Q: What is the significance of the operating force difference?

A: The MSSA2350R has an operating force of 470gf, while the 1825199-1 has an operating force of 600gf. This difference affects the force required to actuate the switch. Applications with specific actuation force requirements must evaluate this parameter within their mechanical design constraints.
