Key Parameters

Substitute Part Grouping Explanation

Substitution of the 7101MD9AV2BES is permissible when the following core parameters align with application requirements:

• Circuit Configuration: Both main and substitute parts must maintain SPDT topology
• Switch Function: On-On operation must be preserved
• Mounting Type: Through hole, right-angle vertical orientation is required
• Termination Style: PC pin termination must be maintained
• Operating Temperature Range: -30°C to 85°C compatibility
• Actuator Type: Standard round actuator configuration

The substitute part 100SP1T2B4M7QE from E-Switch satisfies these core mechanical and functional requirements. Electrical ratings (current and voltage) may exceed application requirements, provided the circuit design accommodates the substitute's specifications without adverse effects.

Parameter Comparison

Engineering Selection Recommendations

Both the 7101MD9AV2BES and 100SP1T2B4M7QE are ROHS3 compliant and carry active product status. Selection between these parts should be based on the following criteria:

Primary Part (7101MD9AV2BES): Select when electrical life requirements exceed 40,000 cycles or when the 6.86mm actuator length is specified for panel integration. This part provides 100,000 cycle electrical life rating.

Substitute Part (100SP1T2B4M7QE): Select when higher current (5A) and voltage (120V AC / 28V DC) ratings are required for future design margin, or when inventory availability of the primary part is constrained. Verify that the 5.08mm actuator length accommodates the mechanical design and panel cutout dimensions. The substitute provides 40,000 cycle electrical life rating.

Both parts maintain identical circuit topology, mounting configuration, and operating temperature range, ensuring functional compatibility in SPDT On-On switching applications.

Frequently Asked Questions (FAQ)

Q: Can the 100SP1T2B4M7QE directly replace the 7101MD9AV2BES in existing designs?

A: Yes, provided the mechanical design accommodates the 5.08mm actuator length (versus 6.86mm on the original part) and the application does not require electrical life exceeding 40,000 cycles. Both parts share identical circuit topology, mounting type, and operating temperature specifications.

Q: What is the significance of the higher current and voltage ratings on the substitute part?

A: The 100SP1T2B4M7QE is rated for 5A at 120V AC and 28V DC, compared to 0.4VA at 20V on the 7101MD9AV2BES. Higher ratings indicate the substitute can handle more demanding electrical loads. For applications operating below these thresholds, the substitute performs identically to the primary part.

Q: Are there packaging or termination differences between these parts?

A: Both parts use PC pin termination and are supplied in bulk packaging. No termination or packaging incompatibilities exist.

Q: What is the impact of the 60,000-cycle difference in electrical life ratings?

A: The 7101MD9AV2BES is rated for 100,000 cycles versus 40,000 cycles for the 100SP1T2B4M7QE. For applications requiring frequent switching operations over extended product lifespans, the primary part provides higher reliability margin. For moderate-duty applications, the substitute meets functional requirements.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both the 7101MD9AV2BES and 100SP1T2B4M7QE are ROHS3 compliant and carry active product status, confirming current manufacturing and regulatory compliance.
