APEM Inc. 5647AB9 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The APEM Inc. 5647AB9 is a panel-mounted toggle switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 6A AC at 125V and 4A DC at 30V. This switch operates in a Mom-Off-Mom (momentary-off-momentary) function and features non-illuminated, epoxy-sealed solder lug terminals. The part is currently active in production with 894 units in stock inventory.

Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable, when supply chain optimization is required, or when design flexibility permits component interchange within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5647AB9 are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Circuit configuration: DPDT
• Switch function: Mom-Off-Mom
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Current rating: Minimum 5A AC, minimum 28V DC
• Voltage rating: Minimum 120V AC, minimum 28V DC
• Panel cutout diameter: 6.35mm to 6.50mm (within mechanical tolerance)
• Actuator length: 11.40mm to 11.43mm (within mechanical tolerance)
• Operating temperature range: Overlap with -30°C to +85°C minimum

The C&K 7205P3 series parts (7205P3CWZGE22 and 7205P3YZQE) meet these criteria with equivalent DPDT Mom-Off-Mom functionality, panel-mount configuration, and solder lug termination. Both substitute parts operate within the required voltage and current parameters for this application category.

Parameter Comparison

Engineering Selection Recommendations

5647AB9 (APEM Inc.): Primary selection for applications requiring 6A AC at 125V or 4A DC at 30V with extended operating temperature range (-40°C to +85°C). Rated for 50,000 electrical cycles. ROHS3 compliant. REACH unaffected status. Suitable for environments with lower temperature extremes.

7205P3CWZGE22 (C&K): Substitute option rated for 5A AC at 120V and 5A DC at 28V. Includes IP67 ingress protection (dust tight, waterproof). Operating temperature range -30°C to +85°C. ROHS3 compliant. REACH affected status. Rated for 40,000 electrical cycles. Suitable for applications requiring environmental sealing.

7205P3YZQE (C&K): Substitute option rated for 5A AC at 120V and 5A DC at 28V. Features epoxy-sealed terminals. Operating temperature range -30°C to +85°C. ROHS3 compliant. REACH affected status. Rated for 40,000 electrical cycles. Higher inventory availability (3,391 units in stock).

All three parts maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating. Selection between substitute parts depends on specific application requirements for environmental protection and inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7205P3 series parts directly replace the APEM 5647AB9?

A: The C&K 7205P3CWZGE22 and 7205P3YZQE are functionally equivalent for DPDT Mom-Off-Mom panel-mount toggle switch applications. Both maintain the same circuit configuration, switch function, mounting type, and termination style. However, the substitute parts are rated for 5A AC at 120V (versus 6A AC at 125V) and 5A DC at 28V (versus 4A DC at 30V). Applications operating at or below 5A AC at 120V and 5A DC at 28V can use these substitutes. Applications requiring the full 6A AC or 4A DC ratings must use the 5647AB9.

Q: What are the mechanical compatibility considerations?

A: The panel cutout diameter differs slightly: 5647AB9 requires 6.50mm, while both C&K substitutes require 6.35mm. Actuator lengths are within 0.03mm tolerance (5647AB9 at 11.40mm, C&K parts at 11.43mm). Panel mounting holes and cutout dimensions must be verified for the specific application before substitution.

Q: Are there temperature range limitations with the substitute parts?

A: The 5647AB9 operates from -40°C to +85°C, while both C&K substitutes operate from -30°C to +85°C. Applications requiring operation below -30°C must use the 5647AB9. Applications within the -30°C to +85°C range can use either substitute.

Q: What is the difference between the two C&K substitute parts?

A: Both 7205P3CWZGE22 and 7205P3YZQE share identical electrical ratings and operating parameters. The 7205P3CWZGE22 includes IP67 ingress protection (dust tight, waterproof). The 7205P3YZQE features epoxy-sealed terminals and has significantly higher inventory availability (3,391 units versus 772 units). Selection depends on environmental sealing requirements and supply chain needs.

Q: Are all parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant. The 5647AB9 has REACH unaffected status, while both C&K substitutes have REACH affected status. Applications subject to REACH regulations should verify compliance requirements with the specific substitute part selected.

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

A: The 5647AB9 is rated for 50,000 electrical cycles, while both C&K substitutes are rated for 40,000 electrical cycles. Applications requiring extended cycle life should use the 5647AB9.
