Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2T18SA5A13 is determined by strict alignment with the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: SPDT
• Switch function: Mom-Off-Mom
• Mounting type: Through Hole
• Termination style: PC Pin
• Actuator type: Standard Round
• Actuator length: 12.70mm
• Operating temperature range: -30°C to 85°C minimum

Electrical Compatibility Parameters:

• AC current rating: minimum 5A (M2T18SA5A13 rated 6A AC)
• AC voltage rating: minimum 120V (M2T18SA5A13 rated 125V AC)
• DC current rating: minimum 3A (M2T18SA5A13 rated 3A DC)
• DC voltage rating: minimum 28V (M2T18SA5A13 rated 30V DC)

The substitute part 100AWSP4T1B4VS2QE meets all critical matching parameters and electrical compatibility thresholds, making it a valid functional equivalent for the obsolete M2T18SA5A13.

Engineering Selection Recommendations

The 100AWSP4T1B4VS2QE from E-Switch is the qualified substitute for the obsolete M2T18SA5A13. Selection rationale is based on the following factors:

Electrical Compatibility: The substitute meets or exceeds all electrical parameters of the original component. AC voltage and current ratings are within acceptable tolerance (120V AC vs. 125V AC; 5A AC vs. 6A AC). DC ratings are superior (5A DC vs. 3A DC; 28V DC vs. 30V DC).

Mechanical Compatibility: Identical mounting configuration, actuator geometry, and termination style ensure direct PCB compatibility without mechanical redesign.

Regulatory Compliance: Both components are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Product Status: The substitute is active in production, ensuring long-term availability and supply chain stability compared to the obsolete original component.

Enhanced Performance: The substitute offers extended electrical life (30,000 cycles vs. 25,000 cycles) and improved ingress protection (IP67 rating), providing operational advantages over the original design.

Frequently Asked Questions (FAQ)

Q: Can the 100AWSP4T1B4VS2QE directly replace the M2T18SA5A13 without PCB modifications?

A: Yes. Both components share identical mounting type (through hole), actuator type (standard round), actuator length (12.70mm), and termination style (PC pin). Direct PCB compatibility is confirmed.

Q: Are there electrical derating considerations when substituting?

A: No derating is required. The substitute meets or exceeds all electrical specifications of the original component across AC and DC operating ranges.

Q: What is the difference in sealing between these components?

A: The M2T18SA5A13 features process sealing. The 100AWSP4T1B4VS2QE provides enhanced environmental protection with IP67 rating (dust tight, waterproof) and epoxy sealed terminals, offering superior ingress protection.

Q: Are both components RoHS compliant?

A: Yes. Both the M2T18SA5A13 and 100AWSP4T1B4VS2QE are ROHS3 compliant and REACH unaffected.

Q: What is the packaging difference?

A: The original M2T18SA5A13 is supplied in standard packaging. The 100AWSP4T1B4VS2QE is supplied in bulk packaging. Verify packaging requirements for your procurement process.

Q: Does the substitute have a longer operational life?

A: Yes. The 100AWSP4T1B4VS2QE is rated for 30,000 electrical cycles compared to 25,000 cycles for the M2T18SA5A13, providing extended component longevity.
