M2T18TXG13-EB Equivalent & Substitute Parts

Part Overview

The M2T18TXG13-EB is a rocker switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with Mom-Off-Mom switch function. This through-hole mounted component is rated for 0.4VA at 28V AC/DC operation with a white paddle actuator. The product is currently obsolete, necessitating identification of equivalent alternatives for ongoing applications and new designs requiring similar electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the M2T18TXG13-EB are identified based on the following critical parameters that determine functional equivalence:

Primary Substitution Criteria:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current rating (0.4VA AC/DC)
• Mounting type (Through Hole)
• Actuator type (Paddle)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)

Voltage Compatibility Consideration: The M2T18TXG13-EB operates at 28V. Substitute parts must meet or exceed this voltage rating to ensure safe operation in the original application circuit.

Identified Substitute Categories:

1. Direct Manufacturer Equivalent: M2018TXG13-EB (NKK Switches) - Same manufacturer, active product status
2. Cross-Manufacturer Alternative: 300AWSP4J2WHTVS2RE (E-Switch) - Functionally equivalent with voltage derating consideration

Parameter Comparison

Engineering Selection Recommendations

M2018TXG13-EB (NKK Switches): This part represents the primary substitute option as it is manufactured by the same supplier as the obsolete M2T18TXG13-EB. Active product status ensures ongoing availability and supply chain continuity. ROHS3 compliance and identical termination specifications support direct integration into existing PCB designs. This option is preferred for applications where manufacturer consistency and supply reliability are critical factors.

300AWSP4J2WHTVS2RE (E-Switch): This cross-manufacturer alternative provides functional equivalence in circuit configuration, switch function, current rating, and mechanical characteristics. Active product status and ROHS3 compliance support regulatory requirements. The IP67 ingress protection rating provides enhanced environmental sealing compared to the original part. However, the voltage rating of 20V AC/DC is lower than the original 28V specification, and electrical life is rated at 30,000 cycles versus 50,000 cycles. This part is suitable for applications operating at or below 20V where the enhanced environmental protection is beneficial.

Frequently Asked Questions (FAQ)

Q: Can the M2018TXG13-EB directly replace the M2T18TXG13-EB? A: Yes. Both parts are manufactured by NKK Switches and share identical circuit configuration (SPDT), switch function (Mom-Off-Mom), mounting type (Through Hole), actuator type and color (White Paddle), and termination style (PC Pin). The M2018TXG13-EB is the active product equivalent.

Q: What is the key limitation of the 300AWSP4J2WHTVS2RE substitute? A: The voltage rating is 20V AC/DC, which is lower than the original M2T18TXG13-EB specification of 28V. This part is suitable only for applications operating at 20V or below. Additionally, electrical life is rated at 30,000 cycles compared to 50,000 cycles for the original part.

Q: Are all substitute parts through-hole mounted with PC pin termination? A: Yes. All identified substitutes maintain through-hole mounting and PC pin termination, ensuring compatibility with existing PCB designs without layout modifications.

Q: Do the substitute parts meet RoHS compliance? A: Yes. Both M2018TXG13-EB and 300AWSP4J2WHTVS2RE are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range for substitute parts? A: The M2018TXG13-EB specifications do not explicitly state the operating temperature range. The 300AWSP4J2WHTVS2RE operates across -30°C to 85°C, matching the original part's temperature range.

Q: Does the 300AWSP4J2WHTVS2RE offer any advantages over the M2018TXG13-EB? A: The 300AWSP4J2WHTVS2RE provides IP67 ingress protection (dust tight and waterproof), offering enhanced environmental sealing. This feature is beneficial for applications requiring moisture or dust resistance. However, this advantage is offset by lower voltage and electrical life ratings.
