Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the E103MD9AGE is determined by the following critical parameters:

• Circuit configuration must be SPDT
• Switch function must be On-Off-On
• Mounting type must be Through Hole, Right Angle
• Termination style must be PC Pin
• Actuator type must be Standard Round
• Operating temperature range must encompass -30°C to 85°C
• RoHS3 compliance status must be maintained
• Current and voltage ratings must meet or exceed application requirements

The identified substitute part 100SP3T2B4M6RE shares the core electrical and mechanical characteristics required for functional equivalence, though with reduced current and voltage ratings that limit its application scope.

Parameter Comparison

Engineering Selection Recommendations

Both the E103MD9AGE and 100SP3T2B4M6RE maintain active product status and ROHS3 compliance, meeting current regulatory requirements. Selection between these components must be based on application-specific electrical requirements.

The E103MD9AGE is suitable for applications requiring 7.5A at 125V AC or 28V DC operation. The 100SP3T2B4M6RE is limited to applications requiring 0.4VA at 20V AC/DC maximum. The actuator length difference (6.86mm versus 5.08mm) may affect panel mounting considerations and operator interface ergonomics.

Frequently Asked Questions (FAQ)

Q: Can the 100SP3T2B4M6RE directly replace the E103MD9AGE in all applications?

A: No. The 100SP3T2B4M6RE has significantly lower current (0.4VA versus 7.5A) and voltage ratings (20V versus 125V AC / 28V DC). Substitution is only valid for applications operating within the lower electrical specifications.

Q: What are the key compatibility criteria for these toggle switches?

A: Both components share SPDT circuit configuration, On-Off-On switching function, through-hole right-angle mounting, PC pin termination, standard round actuator type, identical operating temperature range, and equivalent electrical life ratings.

Q: Does the actuator length difference affect mechanical compatibility?

A: The 1.78mm difference in actuator length (6.86mm versus 5.08mm) may impact panel cutout alignment and operator feel. Panel mounting geometry must be verified for the specific application.

Q: Are both parts RoHS compliant?

A: Yes. Both the E103MD9AGE and 100SP3T2B4M6RE are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the inventory status for these components?

A: The E103MD9AGE has 1064 units in stock. The 100SP3T2B4M6RE has 8787 units in stock.
