Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the 34CMSP41B2M7RT is based on the following critical parameters:

Electrical Compatibility Requirements:

• Circuit type must be SPDT
• Switch function must be Mom-Off-Mom
• Current rating must be 0.4VA or greater (AC/DC)
• Voltage ratings must support minimum 20V AC and 20V DC operation

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole, Right Angle, Vertical
• Termination style must be PC Pin
• Actuator type must be Standard Round
• Bushing must be Unthreaded

Environmental & Compliance Requirements:

• Operating temperature range must encompass -30°C ~ 85°C
• Electrical life must be 30,000 cycles or greater
• RoHS3 compliance must be maintained
• Termination must feature epoxy-sealed design

Two substitute parts meet these criteria with varying performance enhancements:

1. T105LH9AVBE (C&K) - Electrical and mechanical equivalent with identical voltage and current ratings
2. 200AWMSP4T1A1M7QE (E-Switch) - Enhanced performance substitute with higher current and voltage ratings

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Substitution:

The T105LH9AVBE from C&K provides direct electrical and mechanical equivalence to the 34CMSP41B2M7RT. Both parts share identical SPDT circuit configuration, Mom-Off-Mom function, 0.4VA current rating, and 20V AC/DC voltage specifications. Operating temperature ranges, electrical life ratings, and epoxy-sealed terminal construction are identical. Both maintain ROHS3 compliance. The primary difference is actuator length (7.37mm versus 9.40mm), which may affect panel mounting geometry. This part is suitable for direct replacement in applications where the shorter actuator length is compatible with panel cutout dimensions.

Enhanced Performance Substitution:

The 200AWMSP4T1A1M7QE from E-Switch provides superior electrical performance with 3A current capacity and 120V AC / 28V DC voltage ratings, while maintaining identical mechanical mounting and termination specifications. This part includes IP67 ingress protection and extended electrical life of 50,000 cycles. This substitute is appropriate for applications requiring higher current handling or voltage margins, provided that panel cutout dimensions accommodate the 10.16mm actuator length.

Compliance Status:

All three parts maintain ROHS3 compliance and are rated for -30°C ~ 85°C operation. The T105LH9AVBE carries REACH Affected status, while the 34CMSP41B2M7RT and 200AWMSP4T1A1M7QE are REACH Unaffected. All parts are classified under ECCN EAR99 and HTSUS 8536.50.9065.

Frequently Asked Questions (FAQ)

Q: Can the T105LH9AVBE replace the 34CMSP41B2M7RT in all applications?

A: The T105LH9AVBE is electrically and functionally equivalent with identical voltage and current ratings. Substitution is valid provided that the shorter actuator length (7.37mm versus 9.40mm) is compatible with the panel cutout and mechanical assembly. Verify panel geometry before implementation.

Q: What is the primary advantage of the 200AWMSP4T1A1M7QE substitute?

A: The 200AWMSP4T1A1M7QE provides higher current capacity (3A versus 0.4VA) and higher voltage ratings (120V AC / 28V DC versus 20V AC/DC). It also offers extended electrical life (50,000 cycles versus 30,000 cycles) and IP67 ingress protection. This part is suitable for applications requiring enhanced electrical performance or environmental protection.

Q: Are there packaging differences between these parts?

A: Yes. The 34CMSP41B2M7RT and 200AWMSP4T1A1M7QE are supplied in Bulk packaging, while the T105LH9AVBE is supplied in Tray packaging. Packaging selection may affect procurement logistics and handling procedures.

Q: Do all substitute parts maintain the same operating temperature range?

A: Yes. All three parts operate across the identical temperature range of -30°C ~ 85°C, ensuring thermal compatibility across applications.

Q: What is the significance of the different actuator lengths?

A: Actuator length affects the physical engagement depth with the panel cutout. The 34CMSP41B2M7RT has a 9.40mm actuator, the T105LH9AVBE has 7.37mm, and the 200AWMSP4T1A1M7QE has 10.16mm. Panel cutout dimensions must accommodate the selected actuator length to ensure proper mechanical fit and operational function.

Q: Are all parts RoHS3 compliant?

A: Yes. The 34CMSP41B2M7RT, T105LH9AVBE, and 200AWMSP4T1A1M7QE are all ROHS3 Compliant. However, the T105LH9AVBE is REACH Affected, while the other two parts are REACH Unaffected. Verify REACH compliance requirements for your specific application and regulatory jurisdiction.

Q: What does the Mom-Off-Mom function mean?

A: Mom-Off-Mom indicates momentary-off-momentary operation. The switch returns to the center off position when released from either the up or down position. This function is maintained across all three parts.

Q: Can the 200AWMSP4T1A1M7QE be used in low-voltage applications rated for 20V?

A: Yes. The 200AWMSP4T1A1M7QE supports 28V DC and 120V AC operation, which exceeds the 20V requirement. The part is rated for operation at lower voltages within its specified range. However, verify that the higher current capacity (3A) does not introduce unintended circuit behavior in applications designed for 0.4VA operation.
