Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7301SDZQI are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility 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

Electrical Rating Compatibility:

• Current rating: 5A (AC/DC) for full-rated substitutes
• Voltage rating - AC: 120V for full-rated substitutes
• Voltage rating - DC: 28V for full-rated substitutes

E-Switch 100 Series toggle switches meet these mechanical and functional requirements. Three substitute parts are identified:

1. 1003P1T1B1M1QEH - Full electrical rating match (5A, 120V AC, 28V DC)
2. 1003P1T2B1M1QE - Full electrical rating match (5A, 120V AC, 28V DC)
3. 1003P1T1B1M1RE - Reduced electrical rating (0.4VA, 20V AC/DC) - suitable only for lower-power applications

Engineering Selection Recommendations

Full-Rated Substitutes (Recommended for Direct Replacement):

E-Switch 1003P1T1B1M1QEH and E-Switch 1003P1T2B1M1QE are suitable direct substitutes for the C&K 7301SDZQI in applications requiring 5A at 120V AC or 28V DC. Both parts maintain identical electrical ratings, mechanical compatibility, and panel mounting specifications. The primary difference between these two E-Switch options is actuator length: 1003P1T1B1M1QEH provides 10.41mm length, while 1003P1T2B1M1QE provides 5.08mm length. Selection between these two should be based on panel depth and actuator accessibility requirements.

All substitute parts are ROHS3 compliant and active in production. The C&K 7301SDZQI offers higher electrical life (100,000 cycles) compared to E-Switch alternatives (40,000 cycles), which should be considered for high-cycle applications.

Reduced-Rating Substitute (Limited Application):

E-Switch 1003P1T1B1M1RE is electrically rated for 0.4VA at 20V AC/DC only and is suitable only for low-power signal switching applications. This part is not recommended as a substitute for the 7301SDZQI in standard 5A/120V applications.

Frequently Asked Questions (FAQ)

Q: Can E-Switch 1003P1T1B1M1QEH directly replace the C&K 7301SDZQI?

A: Yes. The 1003P1T1B1M1QEH matches all critical electrical and mechanical parameters: 3PDT circuit, 5A current rating, 120V AC / 28V DC voltage ratings, panel mount configuration with 6.35mm circular cutout, 1/4-40 bushing thread, and solder lug termination. The 10.41mm actuator length differs from the original 12.45mm; verify panel depth compatibility before installation.

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

A: Both parts have identical electrical ratings (5A, 120V AC, 28V DC) and mechanical compatibility. The primary difference is actuator length: 1003P1T1B1M1QEH has 10.41mm length, while 1003P1T2B1M1QE has 5.08mm length. Select based on available panel depth and required actuator reach.

Q: Can E-Switch 1003P1T1B1M1RE be used as a substitute?

A: No, not for standard applications. The 1003P1T1B1M1RE is rated for only 0.4VA at 20V AC/DC, significantly below the 7301SDZQI's 5A/120V rating. This part is suitable only for low-power signal switching and will not function properly in circuits designed for the original part's electrical specifications.

Q: Are all substitute parts RoHS compliant?

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

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

A: The C&K 7301SDZQI is rated for 100,000 electrical cycles, while E-Switch 100 Series substitutes are rated for 40,000 cycles. For applications with high switching frequency or extended service life requirements, the original C&K part may be preferable.

Q: Are panel cutout dimensions identical across all parts?

A: Yes. All parts use a circular 6.35mm diameter panel cutout with 1/4-40 bushing thread, ensuring mechanical interchangeability in panel-mount installations.
