Substitute Part Grouping Explanation

Substitute parts for the 7301MPY1ZQE are grouped based on strict electrical and mechanical compatibility criteria:

Primary Substitution Criteria:

• Circuit configuration: 3PDT
• Switch function: On-On
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: Solder Lug
• Operating temperature range: -30°C ~ 85°C
• Actuator material: Brass, Chrome Plated
• Features: Epoxy Sealed Terminals

Electrical Rating Compatibility: Substitutes must maintain equivalent or superior current and voltage ratings. Parts with reduced electrical ratings (lower current or voltage) are listed separately as limited-use alternatives.

Actuator Differences: The main part features an anti-rotation actuator at 5.08mm length. Substitute parts may feature standard round actuators with varying lengths (5.08mm or 10.41mm), which affects panel presentation but not electrical function.

Parameter Comparison

Engineering Selection Recommendations

Full Electrical Rating Match: The E-Switch 1003P1T2B1M1QE provides complete electrical equivalence to the 7301MPY1ZQE with identical 5A/120V AC and 28V DC ratings. This part features a matching 5.08mm actuator length and maintains all mechanical mounting specifications. Both parts are ROHS3 compliant and Active status. The primary difference is actuator type (standard round vs. anti-rotation) and reduced electrical life (40,000 vs. 100,000 cycles).

Extended Actuator Length Alternative: The E-Switch 1003P1T1B1M1QEH maintains full electrical equivalence (5A/120V AC, 28V DC) with identical mounting and termination specifications. The extended 10.41mm actuator length accommodates panel thicknesses or aesthetic requirements where additional actuator projection is needed. ROHS3 compliant and Active status.

Reduced Electrical Rating Alternative: The E-Switch 1003P1T1B1M1RE is suitable only for applications requiring lower electrical performance (0.4VA at 20V AC/DC). This part shares identical mechanical mounting and panel cutout specifications but is restricted to low-voltage, low-current applications. Not suitable as a direct replacement for 5A/120V applications.

All substitute parts maintain ROHS3 compliance and Active product status, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1003P1T2B1M1QE directly replace the C&K 7301MPY1ZQE? A: Yes, for electrical and mechanical compatibility. Both parts feature 3PDT On-On configuration, 5A/120V AC and 28V DC ratings, identical panel cutout dimensions (6.35mm circular), 1/4-40 bushing thread, and solder lug termination. The primary difference is the actuator type (standard round vs. anti-rotation) and electrical life rating (40,000 vs. 100,000 cycles).

Q: What is the significance of the actuator type difference? A: The C&K 7301MPY1ZQE features an anti-rotation actuator, which prevents unintended rotation of the switch handle. E-Switch substitutes use standard round actuators. This affects only the mechanical feel and panel presentation; electrical function remains identical.

Q: Can the 1003P1T1B1M1RE substitute for the 7301MPY1ZQE? A: No. The 1003P1T1B1M1RE is rated for only 0.4VA at 20V AC/DC, significantly below the 7301MPY1ZQE's 5A/120V AC and 28V DC ratings. This part is suitable only for low-voltage, low-current applications and cannot handle the electrical load of the original component.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All listed substitute parts (1003P1T2B1M1QE, 1003P1T1B1M1QEH, and 1003P1T1B1M1RE) are ROHS3 compliant, matching the regulatory status of the C&K 7301MPY1ZQE.

Q: What is the difference between the 1003P1T2B1M1QE and 1003P1T1B1M1QEH? A: Both parts are electrically identical (5A/120V AC, 28V DC, 3PDT On-On). The primary difference is actuator length: the 1003P1T2B1M1QE has a 5.08mm actuator (matching the original), while the 1003P1T1B1M1QEH has a 10.41mm actuator for applications requiring extended panel projection.

Q: Does the reduced electrical life of E-Switch parts affect compatibility? A: Electrical life (100,000 cycles for C&K vs. 40,000 cycles for E-Switch) indicates the number of switching operations before performance degradation. For applications with lower cycle counts, the E-Switch parts are suitable. High-cycle applications may require the C&K part to meet operational longevity requirements.

Q: Are the panel mounting dimensions identical across all parts? A: Yes. All parts feature a circular 6.35mm panel cutout diameter and 1/4-40 bushing thread, ensuring mechanical interchangeability in panel-mount installations.
