Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101MPDCQE are grouped based on strict electrical and mechanical parameter matching:

Primary Substitution Criteria:

• Circuit configuration: SPDT (Single Pole Double Throw)
• Switch function: On-On
• Current rating: 5A (AC/DC)
• Voltage rating: 120V AC / 28V DC
• Mounting type: Panel Mount
• Panel cutout diameter: 6.35mm (Circular)
• Bushing thread: 1/4-40
• Termination style: PC Pin
• Operating temperature: -30°C to 85°C
• RoHS3 compliance

Identified Substitutes:

• E-Switch 100SP1T1B3M2QEH
• E-Switch 100SP1T2B3M2QEH

Non-Equivalent Part (Excluded):

• E-Switch 100SP1T1B1M2REH is not a direct substitute due to reduced current rating (0.4VA vs. 5A) and voltage rating (20V vs. 120V AC/28V DC).

Parameter Comparison

Engineering Selection Recommendations

Both E-Switch 100SP1T1B3M2QEH and 100SP1T2B3M2QEH meet the core electrical and mechanical requirements for substitution with the C&K 7101MPDCQE. All three parts are active production items with ROHS3 compliance and identical voltage/current ratings.

Electrical Equivalence: The substitute parts maintain identical AC/DC voltage and current ratings (120V AC, 28V DC, 5A), ensuring functional compatibility in the same circuit applications.

Mechanical Compatibility: Panel cutout diameter (6.35mm), bushing thread (1/4-40), and termination style (PC Pin) are identical across all three parts, enabling direct mechanical interchange in existing panel installations.

Operational Differences: The C&K 7101MPDCQE features a longer electrical life rating (100,000 cycles vs. 40,000 cycles) and anti-rotation actuator design. The E-Switch substitutes feature standard round actuators with different lengths (10.41mm for 100SP1T1B3M2QEH; 5.08mm for 100SP1T2B3M2QEH), which may affect panel aesthetics and operator feel but do not impact electrical function.

Compliance: All parts maintain ROHS3 compliance and are suitable for applications requiring regulatory adherence.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 100SP1T1B3M2QEH and 100SP1T2B3M2QEH be used interchangeably with the C&K 7101MPDCQE?

A: Yes, both E-Switch parts are electrically and mechanically equivalent. They share identical voltage ratings (120V AC, 28V DC), current rating (5A), circuit configuration (SPDT), panel cutout dimensions (6.35mm), and bushing thread (1/4-40). The primary difference is actuator length, which affects panel protrusion but not electrical function.

Q: What is the difference between the two E-Switch substitute parts?

A: E-Switch 100SP1T1B3M2QEH has an actuator length of 10.41mm, while 100SP1T2B3M2QEH has an actuator length of 5.08mm. Both maintain identical electrical ratings and mechanical mounting specifications. Selection depends on panel depth requirements and operator preference.

Q: Why is E-Switch 100SP1T1B1M2REH not listed as a substitute?

A: The 100SP1T1B1M2REH has a reduced current rating (0.4VA) and voltage rating (20V AC/DC), which do not meet the 5A at 120V AC / 28V DC requirement of the 7101MPDCQE. This part is not electrically equivalent for applications requiring the higher power rating.

Q: Are there any compliance or certification differences between the main part and substitutes?

A: All three parts are ROHS3 compliant and active production items. The C&K 7101MPDCQE is REACH Affected, while the E-Switch substitutes are REACH Unaffected. Both statuses are compliant with current regulations.

Q: What is the impact of the different electrical life ratings?

A: The C&K 7101MPDCQE is rated for 100,000 cycles, while the E-Switch substitutes are rated for 40,000 cycles. For applications with high switching frequency, the C&K part offers extended service life. For standard industrial applications, both ratings are adequate.
