Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101MPDCQE2 are grouped based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

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

Substitute Classification:

Group 1 - Full Electrical & Mechanical Match (100SP1T1B3M2QEH, 100SP1T2B3M2QEH): These E-Switch parts maintain identical electrical ratings (5A, 120V AC, 28V DC), circuit configuration (SPDT), and mechanical interface specifications. Differences in actuator length (10.41mm or 5.08mm versus 6.86mm) do not affect electrical substitution but may require panel design verification for actuator protrusion clearance.

Group 2 - Reduced Electrical Rating (100SP1T1B1M2REH): This E-Switch part operates at 0.4VA with 20V maximum rating, representing a lower-power alternative suitable only for applications where the 7101MPDCQE2's 5A/120V capability exceeds actual circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Equivalence (100SP1T1B3M2QEH or 100SP1T2B3M2QEH):

Select either E-Switch 100SP1T1B3M2QEH or 100SP1T2B3M2QEH when full electrical and mechanical compatibility is required. Both parts maintain the 5A/120V AC and 28V DC ratings, SPDT circuit configuration, and identical mechanical interface (panel cutout, bushing thread, termination). The primary distinction is actuator length: 100SP1T1B3M2QEH provides 10.41mm length while 100SP1T2B3M2QEH provides 5.08mm length. Verify panel design accommodates the selected actuator protrusion. Both parts are active production items with ROHS3 compliance and unlimited moisture sensitivity rating.

For Reduced-Power Applications (100SP1T1B1M2REH):

The E-Switch 100SP1T1B1M2REH is suitable only for applications where circuit requirements do not exceed 0.4VA at 20V maximum. This part maintains mechanical compatibility but operates at significantly reduced electrical ratings. Selection of this part requires confirmation that actual circuit loads are substantially below the 7101MPDCQE2 specifications.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original part's environmental certifications. Electrical life differs: the 7101MPDCQE2 is rated for 100,000 cycles while E-Switch substitutes are rated for 40,000 cycles. Applications requiring extended cycle life should account for this difference.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T1B3M2QEH directly replace the C&K 7101MPDCQE2?

A: Yes, for electrical and mechanical functionality. Both parts feature identical SPDT circuit configuration, 5A current rating, 120V AC and 28V DC voltage ratings, and matching mechanical interfaces (6.35mm panel cutout, 1/4-40 bushing thread, PC pin termination). The actuator length differs (10.41mm versus 6.86mm), requiring verification that panel design accommodates this difference.

Q: What is the difference between 100SP1T1B3M2QEH and 100SP1T2B3M2QEH?

A: Both parts are electrically identical with 5A/120V AC and 28V DC ratings. The difference is actuator length: 100SP1T1B3M2QEH has 10.41mm length while 100SP1T2B3M2QEH has 5.08mm length. Select based on panel design requirements for actuator protrusion clearance.

Q: Can the 100SP1T1B1M2REH substitute for the 7101MPDCQE2?

A: Only if circuit requirements do not exceed 0.4VA at 20V maximum. This part has significantly reduced electrical ratings and is not suitable for applications requiring the full 5A/120V capability of the original part.

Q: Are all substitute parts RoHS compliant?

A: Yes, all listed substitute parts are ROHS3 compliant, matching the original 7101MPDCQE2 certification status.

Q: What is the electrical life difference between the main part and substitutes?

A: The C&K 7101MPDCQE2 is rated for 100,000 electrical cycles, while all E-Switch substitutes are rated for 40,000 cycles. Applications with high cycle count requirements should account for this difference in component selection.

Q: Do all parts use the same termination style?

A: Yes, all parts use PC pin termination, ensuring compatibility with existing PCB designs and connector interfaces.
