MMS22R Equivalent & Substitute Parts

Part Overview

The MMS22R is an active-status slide switch manufactured by TE Connectivity ALCOSWITCH Switches. This DPDT (Double Pole Double Throw) switch is designed for through-hole, right-angle mounting applications requiring 100mA DC switching at 30V. The switch operates with shorting contact timing (MBB) and is rated for 10,000 mechanical and electrical cycles. Substitute parts are identified when equivalent functional performance is required due to inventory constraints, application redesign, or end-of-life considerations for the primary component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the MMS22R with the EG2214 is permissible based on the following alignment of critical electrical and mechanical parameters:

Matching Parameters:

• Circuit configuration: Both DPDT
• Switch function: Both On-On
• Voltage rating: Both 30V DC
• Mounting type: Both through-hole, right-angle
• Termination style: Both PC Pin
• Contact material: Both copper alloy with silver finish
• Switch travel: Both 2.00mm
• Operating force: Both 200gf
• RoHS compliance: Both ROHS3 compliant

Differing Parameters:

• Current rating: MMS22R rated 100mA; EG2214 rated 300mA
• Contact timing: MMS22R uses shorting (MBB); EG2214 uses non-shorting (BBM)
• Operating temperature: MMS22R -20°C to 60°C; EG2214 -20°C to 70°C
• Actuator length: MMS22R 4.29mm; EG2214 4.20mm

The EG2214 provides higher current capacity and extended temperature range, making it suitable for applications where the MMS22R specifications are met or exceeded.

Engineering Selection Recommendations

MMS22R Selection Criteria: The MMS22R is the primary component choice when shorting contact timing (MBB) is a functional requirement and current draw does not exceed 100mA. This part maintains active product status with full ROHS3 compliance and is suitable for applications operating within the -20°C to 60°C temperature envelope.

EG2214 Selection Criteria: The EG2214 serves as a functional substitute when higher current capacity (300mA) is required or when extended operating temperature range (-20°C to 70°C) is specified. The non-shorting contact timing (BBM) of the EG2214 differs from the MMS22R; circuit design must accommodate this timing difference. Both parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment.

Substitution Feasibility: Substitution is electrically and mechanically feasible when the application current requirement does not exceed 300mA and the non-shorting contact timing of the EG2214 is compatible with circuit operation. Physical footprint compatibility is confirmed through matching mounting type, termination style, and switch travel specifications.

Frequently Asked Questions (FAQ)

Q: Can the EG2214 directly replace the MMS22R in all applications?

A: Direct replacement is feasible when the application current does not exceed 300mA and the circuit design accommodates non-shorting (BBM) contact timing. The MMS22R uses shorting (MBB) timing; the EG2214 does not. Circuit topology must be evaluated to confirm compatibility with the contact timing difference.

Q: What is the significance of contact timing differences between these parts?

A: Contact timing refers to the sequence in which switch contacts engage and disengage. Shorting (MBB) timing means the new contact closes before the old contact opens, creating a momentary bridge. Non-shorting (BBM) timing means the old contact opens before the new contact closes, creating a momentary break. Applications sensitive to signal continuity or requiring break-before-make operation must use the EG2214; applications requiring make-before-break operation must use the MMS22R.

Q: Are there physical mounting differences between MMS22R and EG2214?

A: Both parts use through-hole, right-angle mounting with PC pin termination. Actuator length differs slightly (MMS22R 4.29mm versus EG2214 4.20mm); this difference does not affect PCB footprint compatibility. Switch travel and operating force are identical.

Q: What is the current capacity difference, and when does it matter?

A: The MMS22R is rated for 100mA DC; the EG2214 is rated for 300mA DC. The higher rating of the EG2214 provides design margin for applications approaching 100mA. If application current exceeds 100mA, the EG2214 is required. If application current is below 100mA, either part is electrically suitable.

Q: Do both parts meet the same regulatory compliance standards?

A: Both the MMS22R and EG2214 are ROHS3 compliant. Both carry active product status. Regulatory compliance is equivalent between the two parts.

Q: What is the operating temperature consideration for substitution?

A: The MMS22R operates from -20°C to 60°C; the EG2214 operates from -20°C to 70°C. If the application requires operation above 60°C, the EG2214 is required. If operation remains within -20°C to 60°C, both parts are suitable.
