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

Part Overview

The C&K 7403SHZBE 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 a temperature range of -30°C to 85°C. The part is currently active in production with 736 units in stock. Equivalent and substitute parts are identified when mechanical compatibility, electrical circuit configuration, and operational parameters align within acceptable tolerances for the intended application.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7403SHZBE are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Compatibility Criteria:

• Circuit configuration: 4PDT
• Switch function: On-Off-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
• Electrical life: 40,000 Cycles

Electrical Rating Considerations: Substitute parts must maintain compatibility with the application's voltage and current requirements. The 7403SHZBE operates at 0.4VA/20V. Substitute parts with higher current and voltage ratings (such as the E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH rated at 5A/120V AC and 28V DC) are electrically compatible for applications designed for the lower-rated main part, as they provide superior electrical capacity.

Identified Substitutes:

• E-Switch 1004P3T1B1M1QE
• E-Switch 1004P3T1B1M1QEH

Both parts share identical mechanical specifications and circuit configuration with the main part, differing only in electrical ratings and REACH compliance status.

Parameter Comparison

Engineering Selection Recommendations

Primary Part - C&K 7403SHZBE: Select this part when the application requires exact electrical specifications of 0.4VA at 20V AC/DC. The part is active in production with established supply availability (736 units in stock). ROHS3 compliance and epoxy-sealed terminals support industrial and harsh environment applications.

Substitute Parts - E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH: Both E-Switch alternatives provide identical mechanical and circuit compatibility with superior electrical ratings (5A at 120V AC / 28V DC). These parts are suitable for applications where the 7403SHZBE is unavailable or when higher electrical capacity is required within the same mechanical footprint. The 1004P3T1B1M1QEH variant offers additional inventory availability (1991 units in stock) compared to the 1004P3T1B1M1QE (764 units in stock).

Compliance Considerations: All three parts maintain ROHS3 compliance and identical operating temperature ranges. The E-Switch variants carry REACH Unaffected status, whereas the C&K 7403SHZBE is REACH Affected. Applications subject to REACH regulations may benefit from E-Switch substitutes.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1004P3T1B1M1QE replace the C&K 7403SHZBE in my application?

A: Yes, provided your application operates at or below the C&K part's electrical specifications (0.4VA at 20V AC/DC). The E-Switch part shares identical mechanical specifications, circuit configuration (4PDT), switch function (On-Off-On), panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), and termination style (solder lug). The higher electrical rating of the E-Switch part does not create compatibility issues in lower-power applications.

Q: What is the difference between E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH?

A: Both parts are electrically and mechanically identical. The primary difference is REACH compliance status and inventory availability. The 1004P3T1B1M1QEH has higher stock levels (1991 units versus 764 units) and carries REACH Unaffected designation, making it preferable for applications with REACH regulatory requirements or when supply continuity is critical.

Q: Are there any mechanical differences between these parts?

A: Actuator length differs slightly: the C&K 7403SHZBE has a 10.67mm actuator length, while both E-Switch alternatives have 10.41mm actuators. This 0.26mm difference is negligible for standard panel-mount applications and does not affect functional compatibility or panel cutout requirements.

Q: What certifications do these parts carry?

A: All three parts are ROHS3 compliant. The C&K 7403SHZBE is REACH Affected, while the E-Switch 1004P3T1B1M1QE and 1004P3T1B1M1QEH are REACH Unaffected. All parts carry EAR99 ECCN classification and HTSUS code 8536.50.9065.

Q: Can I use these parts in applications exceeding 0.4VA at 20V?

A: The E-Switch substitutes (1004P3T1B1M1QE and 1004P3T1B1M1QEH) are rated for 5A at 120V AC and 28V DC, making them suitable for higher-power applications. The C&K 7403SHZBE is limited to its specified 0.4VA at 20V rating and should not be used in applications exceeding these parameters.
