C&K 7303SCWZGE Toggle Switch 3PDT Equivalent & Substitute Parts

Part Overview

The C&K 7303SCWZGE is an active-status toggle switch featuring 3PDT (three-pole, double-throw) circuitry with panel mount configuration. This non-illuminated switch is rated for 5A at 120V AC and 28V DC, designed for applications requiring reliable on-off-on switching functionality. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical compatibility, and circuit configuration to ensure direct functional replacement in target applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7303SCWZGE are qualified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Circuit configuration: 3PDT
• Switch function: On-Off-On
• Current rating: 5A minimum (AC/DC)
• Voltage rating: 120V AC minimum, 28V DC minimum
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Panel cutout dimensions: Circular 6.35mm diameter
• Bushing thread: 1/4-40
• Operating temperature range: -30°C to 85°C minimum
• Electrical life: 40,000 cycles minimum

Substitute Parts Identified:

1. E-Switch 1003P3T1B1M1QE – Meets all primary matching criteria with identical electrical ratings and mechanical compatibility.

2. E-Switch 1003P3T1B1M1QEH – Meets all primary matching criteria with identical electrical ratings and mechanical compatibility. Differs only in packaging (Bulk vs. Tray).

3. APEM Inc. 5659AB – Meets primary matching criteria with higher current rating (6A AC, 4A DC) and slightly elevated voltage rating (125V AC, 30V DC). Panel cutout diameter is 6.50mm, requiring minor mechanical adjustment.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active product status and ROHS3 compliance, ensuring regulatory alignment with the original 7303SCWZGE specification.

E-Switch 1003P3T1B1M1QE and 1003P3T1B1M1QEH provide direct electrical and mechanical equivalence. These parts are distinguished only by packaging format (Tray vs. Bulk). Selection between these two variants depends on procurement and inventory management requirements rather than functional performance.

APEM Inc. 5659AB offers higher electrical ratings (6A AC, 4A DC at 125V AC, 30V DC) and extended lower temperature operation (-40°C vs. -30°C). The panel cutout diameter of 6.50mm represents a 0.15mm increase from the 7303SCWZGE specification, requiring panel modification or use of a larger bushing. This part is suitable for applications requiring enhanced electrical margin or expanded temperature range, provided mechanical accommodation is feasible.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1003P3T1B1M1QE directly replace the C&K 7303SCWZGE without modification?

A: Yes. The 1003P3T1B1M1QE matches all critical electrical parameters (5A at 120V AC, 28V DC), circuit configuration (3PDT), mechanical mounting specifications (Panel Mount, 1/4-40 bushing thread, 6.35mm panel cutout), and termination style (Solder Lug). No panel modification is required.

Q: What is the difference between E-Switch 1003P3T1B1M1QE and 1003P3T1B1M1QEH?

A: Both parts are electrically and mechanically identical. The difference is packaging: 1003P3T1B1M1QE is supplied in Tray format, while 1003P3T1B1M1QEH is supplied in Bulk format. Selection depends on procurement quantity and inventory handling requirements.

Q: Can the APEM Inc. 5659AB be used as a substitute?

A: The 5659AB is functionally compatible but requires mechanical consideration. It features a 6.50mm panel cutout diameter compared to the 6.35mm specification of the 7303SCWZGE. Panel modification or a larger bushing is necessary for installation. The 5659AB offers higher electrical ratings (6A AC, 4A DC) and extended lower temperature operation (-40°C), making it suitable for demanding applications where these enhancements are beneficial.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The 7303SCWZGE and all identified substitute parts (1003P3T1B1M1QE, 1003P3T1B1M1QEH, and 5659AB) are ROHS3 compliant.

Q: What is the significance of the IP67 rating on the 7303SCWZGE?

A: The IP67 rating indicates dust-tight and waterproof ingress protection. The E-Switch and APEM substitute parts do not specify an ingress protection rating. If IP67 protection is a functional requirement, the 7303SCWZGE must be retained or equivalent IP67-rated alternatives must be sourced.

Q: Do the substitute parts have the same electrical life rating?

A: Yes. The 7303SCWZGE, 1003P3T1B1M1QE, 1003P3T1B1M1QEH, and 5659AB all specify 40,000 electrical life cycles.
