Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following critical parameters:

• Circuit Configuration: Must be 3PDT
• Switch Function: Must be On-On
• Mounting Type: Must be Panel Mount
• Panel Cutout Dimensions: Must be Circular - 6.35mm Dia
• Bushing Thread: Must be 1/4-40
• Termination Style: Must be Solder Lug
• Operating Temperature Range: Must support -30°C to 85°C minimum
• RoHS Status: Must be ROHS3 Compliant

Substitute parts are grouped based on electrical rating compatibility:

Group 1 - Full Electrical Equivalents (5A @ 120V AC / 28V DC):

• 1003P1T1B1M1QEH (E-Switch)
• 1003P1T2B1M1QE (E-Switch)

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

• 1003P1T1B1M1RE (E-Switch)

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Equivalence (5A @ 120V AC / 28V DC):

E-Switch 1003P1T1B1M1QEH and 1003P1T2B1M1QE are electrically equivalent to the C&K 7301SPCWZGE. Both parts maintain identical voltage and current ratings, panel cutout dimensions, bushing thread specifications, and termination style. Both are ROHS3 compliant and support the required operating temperature range. The primary differences are actuator type (standard round versus anti-rotation) and actuator length. The 1003P1T1B1M1QEH features a 10.41mm actuator length closely matching the original 10.67mm specification, while the 1003P1T2B1M1QE has a shorter 5.08mm actuator. Electrical life is reduced to 40,000 cycles compared to the original 100,000 cycles.

For Reduced Electrical Rating Applications (0.4VA @ 20V AC/DC):

E-Switch 1003P1T1B1M1RE is suitable only for applications with maximum voltage requirements of 20V AC/DC and current loads of 0.4VA or less. This part shares identical mechanical specifications and panel mounting characteristics but operates at significantly lower electrical ratings. Selection of this part requires confirmation that application voltage and current demands do not exceed these limits.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and support the -30°C to 85°C operating temperature range. The original C&K part specifies IP67 ingress protection; substitute parts do not provide this specification. Applications requiring IP67 protection should retain the original C&K 7301SPCWZGE.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1003P1T1B1M1QEH be used as a direct replacement for the C&K 7301SPCWZGE?

A: Yes, for applications requiring 5A at 120V AC or 28V DC. Both parts share identical electrical ratings, panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and solder lug termination. The primary difference is the actuator type (standard round versus anti-rotation) and reduced electrical life (40,000 versus 100,000 cycles). If IP67 ingress protection is required, the original C&K part should be retained.

Q: What is the difference between the 1003P1T1B1M1QEH and 1003P1T2B1M1QE?

A: Both E-Switch parts are electrically identical (5A @ 120V AC / 28V DC) and share the same panel mounting specifications. The primary difference is actuator length: the 1003P1T1B1M1QEH has a 10.41mm actuator length, while the 1003P1T2B1M1QE has a 5.08mm actuator length. Selection depends on panel thickness and actuator protrusion requirements.

Q: When should the E-Switch 1003P1T1B1M1RE be selected?

A: The 1003P1T1B1M1RE is suitable only for low-voltage, low-current applications with maximum requirements of 20V AC/DC and 0.4VA. It shares the same mechanical specifications and panel mounting characteristics as the other E-Switch alternatives but operates at significantly reduced electrical ratings. This part is not suitable for applications requiring 5A at 120V.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The C&K 7301SPCWZGE and all three E-Switch substitute parts (1003P1T1B1M1QEH, 1003P1T2B1M1QE, and 1003P1T1B1M1RE) are ROHS3 compliant.

Q: What is the impact of reduced electrical life in the E-Switch alternatives?

A: The E-Switch parts are rated for 40,000 electrical cycles compared to 100,000 cycles for the C&K original. For applications with high switching frequency or extended operational life requirements, the reduced cycle rating should be evaluated against expected service life demands.

Q: Does the absence of IP67 specification in E-Switch parts affect compatibility?

A: The C&K 7301SPCWZGE specifies IP67 (dust tight, waterproof) ingress protection. The E-Switch substitute parts do not provide this specification. Applications requiring sealed operation in harsh environments should retain the original C&K part or confirm that the E-Switch alternative meets environmental protection requirements through alternative means.
