Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7103MD9AGE are identified based on the following critical parameters that determine functional equivalence:

Electrical Compatibility Criteria:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Current and voltage ratings within application tolerance
• Operating temperature range (-30°C to 85°C)
• Electrical life (40,000 cycles minimum)

Mechanical Compatibility Criteria:

• Mounting type (Through Hole, Right Angle)
• Actuator type (Standard Round)
• Termination style (PC Pin)
• Bushing thread specification (Unthreaded)

Compliance Criteria:

• RoHS3 compliance
• ECCN classification (EAR99)
• HTSUS code alignment (8536.50.9065)

The E-Switch 100SP3T2B4M6RE meets the core mechanical and functional requirements as an SPDT toggle switch with through-hole, right-angle mounting and PC pin termination. However, this substitute operates at reduced electrical ratings (0.4VA at 20V AC/DC), making it suitable only for applications where the lower voltage and current specifications are acceptable.

Parameter Comparison

Engineering Selection Recommendations

C&K 7103MD9AGE is the primary selection for applications requiring 5A switching capacity at 120V AC or 28V DC. This part maintains active product status with ROHS3 compliance and REACH affected designation, confirming current manufacturing support and regulatory alignment for industrial and commercial applications.

E-Switch 100SP3T2B4M6RE serves as a substitute only in applications where electrical requirements do not exceed 0.4VA at 20V AC/DC. This part is ROHS3 compliant and REACH unaffected, indicating simplified regulatory status. The reduced actuator length (5.08mm versus 6.86mm) may require panel cutout verification. Selection of this substitute is contingent upon circuit voltage and current demands remaining within its specified ratings.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP3T2B4M6RE directly replace the C&K 7103MD9AGE in all applications?

A: No. The E-Switch substitute operates at significantly lower electrical ratings (0.4VA at 20V versus 5A at 120V AC). Direct substitution is only valid for applications where circuit voltage does not exceed 20V and current demand does not exceed 0.4VA.

Q: What are the critical parameters that must match for toggle switch substitution?

A: Circuit configuration (SPDT), switch function (On-Off-On), mounting type (Through Hole, Right Angle), termination style (PC Pin), and operating temperature range (-30°C to 85°C) must align. Electrical ratings (current and voltage) must meet or exceed application requirements.

Q: Does the difference in actuator length affect mechanical compatibility?

A: Actuator length difference (6.86mm versus 5.08mm) may impact panel cutout clearance and user interface feel. Verify panel mounting dimensions and actuator engagement depth before substitution.

Q: Are both parts compliant with current regulations?

A: Both parts are ROHS3 compliant and classified as EAR99 for export control. The C&K part is REACH affected; the E-Switch part is REACH unaffected. Confirm regulatory requirements for your specific application and region.

Q: What is the electrical life expectancy for both parts?

A: Both the C&K 7103MD9AGE and E-Switch 100SP3T2B4M6RE are rated for 40,000 electrical cycles, providing equivalent operational longevity under their respective electrical specifications.
