C&K 7403P3DZBE Toggle Switch 4PDT Equivalent & Substitute Parts

Part Overview

The C&K 7403P3DZBE is a panel-mount toggle switch with 4PDT (four-pole double-throw) circuit configuration, rated for 0.4VA at 20V AC/DC. This switch is designed for On-Off-On applications requiring epoxy-sealed terminals and operates across -30°C to 85°C. The part is currently active in production with 800 units in stock.

Equivalent and substitute parts are identified when applications require higher current ratings, increased voltage capacity, or alternative sourcing while maintaining core mechanical and electrical compatibility within the 4PDT toggle switch category.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7403P3DZBE are qualified based on the following criteria:

Mechanical Compatibility:

• 4PDT circuit configuration (required)
• Panel mount installation method (required)
• Circular 6.35mm diameter panel cutout (required)
• 1/4-40 bushing thread (required)
• Solder lug termination (required)
• On-Off-On switch function (required)

Electrical Compatibility:

• Current rating equal to or greater than 0.4VA
• Voltage rating (AC and DC) equal to or greater than 20V
• Operating temperature range encompassing -30°C to 85°C
• Electrical life rating of 40,000 cycles or greater

Compliance & Status:

• Active product status
• ROHS3 compliance
• Epoxy-sealed terminals

The E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH meet all mechanical requirements and exceed electrical specifications with 5A current rating at 120V AC and 28V DC, making them suitable substitutes for applications requiring higher power handling capacity.

Parameter Comparison

Engineering Selection Recommendations

Both E-Switch substitute parts (1004P3T1B1M1QE and 1004P3T1B1M1QEH) are qualified alternatives to the C&K 7403P3DZBE based on active product status and ROHS3 compliance. The substitutes provide enhanced electrical performance with 5A current capacity and 120V AC rating, exceeding the original part's 0.4VA and 20V specifications.

Selection between the two E-Switch variants should be based on inventory availability and application requirements. The 1004P3T1B1M1QEH offers higher stock levels (1991 units) compared to 1004P3T1B1M1QE (764 units). Both parts maintain identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1004P3T1B1M1QE or 1004P3T1B1M1QEH be used as direct replacements for the C&K 7403P3DZBE?

A: Yes. Both E-Switch parts maintain identical mechanical interfaces (6.35mm panel cutout, 1/4-40 bushing thread, solder lug termination) and identical circuit configuration (4PDT On-Off-On). The substitutes exceed the original part's electrical ratings and operate within the same temperature range.

Q: What are the key differences between the substitute parts and the original?

A: The primary difference is current and voltage capacity. The E-Switch substitutes are rated for 5A at 120V AC and 28V DC, compared to the C&K original at 0.4VA and 20V. All other mechanical and functional parameters remain equivalent.

Q: Are there differences between the two E-Switch substitute part numbers?

A: The 1004P3T1B1M1QE and 1004P3T1B1M1QEH are electrically and mechanically identical. The difference is inventory availability, with 1004P3T1B1M1QEH offering higher stock levels.

Q: What compliance certifications apply to these substitute parts?

A: All parts listed are ROHS3 compliant and feature epoxy-sealed terminals. The C&K original is REACH Affected; the E-Switch substitutes are REACH Unaffected.

Q: Are the panel mounting dimensions identical across all three parts?

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