C&K 7301SPHZGI Toggle Switch 3PDT Equivalent & Substitute Parts

Part Overview

The C&K 7301SPHZGI is a panel-mount toggle switch with 3PDT (three-pole, double-throw) configuration, rated for 5A at 120V AC and 28V DC. This switch is designed for on-on applications with anti-rotation actuator and epoxy potting for environmental protection. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when applications require alternative sourcing due to inventory constraints, lead time considerations, or design flexibility within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

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

Mandatory Matching Parameters:

• 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 to 85°C
• Actuator material: Brass, Chrome Plated

Electrical Performance Parameters:

• Current rating: 5A (AC/DC) minimum
• Voltage rating - AC: 120V minimum
• Voltage rating - DC: 28V minimum

Three E-Switch parts from the 100 Series meet these substitution criteria with variations in actuator type and length:

1. 1003P1T1B1M1QEH - Matches all mandatory parameters with standard round actuator (10.41mm length)
2. 1003P1T2B1M1QE - Matches all mandatory parameters with standard round actuator (5.08mm length, shorter profile)
3. 1003P1T1B1M1RE - Matches mechanical and environmental parameters but operates at reduced electrical ratings (0.4VA at 20V AC/DC)

Parameter Comparison

Engineering Selection Recommendations

Full Electrical Rating Substitutes (1003P1T1B1M1QEH and 1003P1T2B1M1QE):

E-Switch 1003P1T1B1M1QEH and 1003P1T2B1M1QE are direct substitutes for applications requiring 5A at 120V AC and 28V DC operation. Both parts maintain identical electrical specifications, panel mounting geometry, and environmental compliance. Selection between these two depends on actuator length requirements: 1003P1T1B1M1QEH provides 10.41mm actuator length (comparable to the original 10.67mm), while 1003P1T2B1M1QE offers a shorter 5.08mm profile for space-constrained panel designs. Both are ROHS3 compliant and active in production.

Reduced Rating Substitute (1003P1T1B1M1RE):

E-Switch 1003P1T1B1M1RE is suitable only for applications operating at 0.4VA maximum at 20V AC/DC or lower. This part shares identical mechanical and environmental specifications but operates at significantly reduced electrical capacity. Use this substitute only when application requirements do not exceed 0.4VA at 20V.

All three E-Switch alternatives are ROHS3 compliant, active products with unlimited moisture sensitivity rating (MSL 1).

Frequently Asked Questions (FAQ)

Q: Can 1003P1T1B1M1QEH directly replace 7301SPHZGI in my application?

A: Yes, if your application requires 5A at 120V AC or 28V DC operation. The 1003P1T1B1M1QEH maintains identical electrical ratings, 3PDT circuit configuration, panel cutout dimensions (6.35mm circular), and 1/4-40 bushing thread. The primary difference is actuator type (standard round versus anti-rotation) and slightly shorter actuator length (10.41mm versus 10.67mm). Verify panel clearance for the actuator profile.

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

A: Both parts are electrically identical (5A at 120V AC, 28V DC) with matching 3PDT configuration and panel mounting specifications. The difference is actuator length: 1003P1T1B1M1QEH has a 10.41mm actuator, while 1003P1T2B1M1QE has a 5.08mm actuator. Choose based on available panel depth and actuator engagement requirements.

Q: Can I use 1003P1T1B1M1RE as a substitute?

A: Only if your application operates at 0.4VA maximum at 20V AC/DC or lower. This part has reduced electrical ratings compared to the original 7301SPHZGI (5A at 120V AC). Do not use this substitute in applications requiring higher voltage or current specifications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The C&K 7301SPHZGI and all three E-Switch alternatives (1003P1T1B1M1QEH, 1003P1T2B1M1QE, and 1003P1T1B1M1RE) are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity).

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

A: The C&K 7301SPHZGI is rated for 100,000 electrical cycles. The E-Switch alternatives are rated for 40,000 cycles. For applications with high cycle count requirements, verify that 40,000 cycles meets your operational life expectancy.

Q: Do the substitute parts have the same panel cutout and bushing specifications?

A: Yes. All substitute parts use identical panel cutout dimensions (circular 6.35mm diameter) and bushing thread (1/4-40), ensuring mechanical compatibility with existing panel designs.
