Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7101MD9ASE is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration (SPDT)
• Switch function (On-On)
• Mounting type (Through Hole, Right Angle)
• Termination style (PC Pin)
• Actuator type (Standard Round)
• Operating temperature range (-30°C to 85°C)

Conditional Parameters (Application-Dependent):

• Current rating must meet or exceed application requirements
• Voltage ratings (AC and DC) must meet or exceed application requirements
• Electrical life must be sufficient for the intended duty cycle

The E-Switch 100SP1T2B4M6RE shares the same circuit configuration, mounting type, termination style, and operating temperature range as the 7101MD9ASE. However, this substitute has reduced current and voltage ratings, making it suitable only for applications with lower power requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the C&K 7101MD9ASE and E-Switch 100SP1T2B4M6RE are active production components with ROHS3 compliance. Selection between these parts must be based on application voltage and current requirements.

The C&K 7101MD9ASE is suitable for applications requiring 5A switching capacity at voltages up to 120V AC or 28V DC, with extended electrical life of 100,000 cycles.

The E-Switch 100SP1T2B4M6RE is limited to applications with maximum current of 0.4VA and maximum voltages of 20V AC/DC, with electrical life of 40,000 cycles. This substitute is appropriate only for low-power signal switching applications that do not exceed these electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T2B4M6RE replace the C&K 7101MD9ASE in all applications?

A: No. The E-Switch substitute has significantly lower current (0.4VA versus 5A) and voltage ratings (20V versus 120V AC/28V DC). Substitution is valid only for applications operating within the lower electrical specifications.

Q: What are the key compatibility factors between these switches?

A: Both switches share identical circuit configuration (SPDT), switch function (On-On), mounting type (Through Hole, Right Angle), termination style (PC Pin), and operating temperature range (-30°C to 85°C). These parameters ensure mechanical and electrical interface compatibility.

Q: How do the actuator lengths differ?

A: The C&K 7101MD9ASE has an actuator length of 6.86mm, while the E-Switch 100SP1T2B4M6RE has 5.08mm. This difference may affect panel mounting depth and operator feel, requiring mechanical verification in the target application.

Q: What is the difference in electrical life between these parts?

A: The C&K 7101MD9ASE is rated for 100,000 cycles, while the E-Switch 100SP1T2B4M6RE is rated for 40,000 cycles. Applications with high switching frequency should account for this difference in component selection.

Q: Are both parts RoHS compliant?

A: Yes, both the C&K 7101MD9ASE and E-Switch 100SP1T2B4M6RE are ROHS3 compliant and suitable for applications requiring RoHS certification.
