Substitute Part Grouping Explanation

Substitute parts for the 7201L2YCQE are grouped based on the following substitution criteria:

Primary Compatibility Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• 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
• Actuator material: Brass with plating

Electrical Parameter Ranges: Substitutes must operate within the voltage and current specifications of the application. The 7201L2YCQE operates at 5A/120V AC and 28V DC. Substitute parts may have different electrical ratings; selection depends on application requirements.

Substitute Categories:

Group 1 - Full Electrical Equivalence (5A/120V AC):

• 100DP1T1B1M2QEH (E-Switch): Matches primary electrical ratings (5A/120V AC, 28V DC) with identical mechanical interface. Differs in actuator length (10.41mm vs 13.97mm) and electrical life (40,000 vs 100,000 cycles).

Group 2 - Reduced Electrical Rating (0.4VA/20V AC/DC):

• 100DP1T6B15M2RE (E-Switch): Lower electrical rating suitable for low-power applications. Flat anti-rotation actuator type differs from standard round.
• 2-1825138-4 (TE Connectivity ALCOSWITCH): Reduced electrical rating with significantly lower electrical life (6,000 cycles). Nickel-plated actuator material differs from chrome plating.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring 5A/120V AC operation: The 100DP1T1B1M2QEH (E-Switch) provides electrical equivalence to the 7201L2YCQE. Both parts are ROHS3 compliant and share identical voltage and current ratings. The primary differences are reduced electrical life (40,000 vs 100,000 cycles) and shorter actuator length (10.41mm vs 13.97mm). The E-Switch part is REACH unaffected, which may be advantageous in certain supply chain contexts. Mechanical fit must be verified for the shorter actuator length in panel-mount applications.

For applications requiring reduced electrical ratings (0.4VA/20V AC/DC): Both 100DP1T6B15M2RE (E-Switch) and 2-1825138-4 (TE Connectivity) are suitable for low-power switching. The E-Switch part features a flat anti-rotation actuator and maintains 40,000 electrical cycles. The TE Connectivity part operates at significantly reduced electrical life (6,000 cycles) and uses nickel plating instead of chrome. Both are ROHS3 compliant. The E-Switch option is REACH unaffected.

Compliance Considerations: All substitute parts maintain ROHS3 compliance. The 100DP1T1B1M2QEH and 100DP1T6B15M2RE are REACH unaffected, while 2-1825138-4 is REACH affected, matching the original part status.

Frequently Asked Questions (FAQ)

Q: Can the 100DP1T1B1M2QEH directly replace the 7201L2YCQE in all applications? A: The 100DP1T1B1M2QEH provides electrical equivalence for 5A/120V AC applications and shares the same mechanical interface (panel cutout, bushing thread, termination). However, the actuator length is 4.66mm shorter (10.41mm vs 13.97mm), which may affect panel clearance or operator feel. Mechanical fit must be verified for the specific application.

Q: What is the difference between the two E-Switch substitute parts? A: The 100DP1T1B1M2QEH is rated for 5A/120V AC (matching the original part), while the 100DP1T6B15M2RE is rated for 0.4VA/20V AC/DC (reduced power). The 100DP1T6B15M2RE also features a flat anti-rotation actuator instead of a standard round actuator. Selection depends on application electrical requirements.

Q: Why does the 2-1825138-4 have significantly lower electrical life? A: The 2-1825138-4 is rated for only 6,000 electrical cycles compared to 100,000 cycles for the original part and 40,000 cycles for the E-Switch alternatives. This part is suitable only for low-cycle-count applications. Applications requiring frequent switching should use alternatives with higher electrical life ratings.

Q: Are all substitute parts ROHS3 compliant? A: Yes, all substitute parts listed are ROHS3 compliant. However, REACH status differs: the E-Switch parts (100DP1T1B1M2QEH and 100DP1T6B15M2RE) are REACH unaffected, while the TE Connectivity part (2-1825138-4) is REACH affected, matching the original C&K part.

Q: What packaging is available for substitute parts? A: The 100DP1T1B1M2QEH and 100DP1T6B15M2RE are available in bulk packaging. The 2-1825138-4 is also available in bulk packaging. The original 7201L2YCQE is supplied in tray packaging.

Q: Can reduced-rating parts be used in higher-power applications? A: No. The 100DP1T6B15M2RE and 2-1825138-4 are rated for 0.4VA/20V AC/DC and must not be used in applications exceeding these electrical specifications. Use only parts with electrical ratings equal to or greater than application requirements.
