APEM Inc. 5642AB Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The APEM Inc. 5642AB 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 features a standard round actuator with solder lug termination and is designed for On-Momentary operation. The product is Active status with ROHS3 compliance and unlimited moisture sensitivity rating. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical mounting specifications, and functional circuit configuration to support component sourcing flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5642AB are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Circuit configuration: DPDT
• Switch function: On-Momentary operation
• Mounting type: Panel Mount with 1/4-40 bushing thread
• Termination style: Solder Lug
• Electrical ratings: Minimum 5A AC at 120V and 4A DC at 28V
• Actuator type: Standard Round
• Epoxy sealed terminals for environmental protection

The 5642AB operates at higher AC voltage (125V) and DC voltage (30V) compared to substitute options. Substitutes rated at 120V AC and 28V DC remain compatible for applications within these lower voltage specifications. Panel cutout diameter tolerance (6.35mm to 6.50mm) and actuator length variation (10.41mm to 10.67mm) fall within acceptable mechanical mounting ranges for panel-mounted toggle switches.

Parameter Comparison

Engineering Selection Recommendations

5642AB (APEM Inc.) - Primary specification. Highest voltage and current ratings (6A @ 125V AC, 4A @ 30V DC). Extended operating temperature range (-40°C to 85°C). Highest electrical life rating (50,000 cycles). ROHS3 compliant with REACH Unaffected status. Recommended for applications requiring maximum electrical performance and extended temperature operation.

100DP2T1B1M1QEH (E-Switch) - Substitute option with reduced electrical ratings (5A @ 120V AC, 5A @ 28V DC). Operating temperature range -30°C to 85°C. Electrical life 40,000 cycles. ROHS3 compliant with REACH Unaffected status. Suitable for applications operating within 120V AC and 28V DC specifications with standard temperature requirements.

7208SYZQE (C&K) - Substitute option with electrical ratings matching E-Switch (5A @ 120V AC, 5A @ 28V DC). Operating temperature range -30°C to 85°C. Electrical life 40,000 cycles. ROHS3 compliant. REACH Affected status requires regulatory consideration in applications subject to REACH compliance requirements.

Frequently Asked Questions (FAQ)

Q: Can the 100DP2T1B1M1QEH or 7208SYZQE be used as direct replacements for the 5642AB?

A: Both parts are functionally compatible for applications operating at or below 120V AC and 28V DC. The 5642AB's higher voltage ratings (125V AC, 30V DC) provide additional margin. If your application operates within the lower voltage specifications, either substitute is mechanically and electrically compatible based on matching DPDT circuit, On-Momentary function, panel mount configuration, and solder lug termination.

Q: What are the mechanical compatibility considerations?

A: All three parts share identical bushing thread specifications (1/4-40) and panel cutout diameter tolerance (6.35mm to 6.50mm). Actuator length variation ranges from 10.41mm to 10.67mm, which is within acceptable tolerance for standard panel-mounted toggle switch installations. No mechanical modification is required for substitution.

Q: How do electrical life ratings affect component selection?

A: The 5642AB is rated for 50,000 electrical cycles, while both substitute parts are rated for 40,000 cycles. For applications with high switching frequency or extended operational life requirements, the 5642AB provides additional cycle margin. For standard-duty applications, the 40,000-cycle rating of substitute parts is sufficient.

Q: What is the significance of REACH status differences?

A: The 5642AB and 100DP2T1B1M1QEH are REACH Unaffected, indicating no regulatory restriction under REACH regulations. The 7208SYZQE is REACH Affected, requiring compliance verification for applications subject to REACH requirements. All three parts are ROHS3 compliant.

Q: Are there temperature range limitations for substitution?

A: The 5642AB operates from -40°C to 85°C, while both substitute parts operate from -30°C to 85°C. For applications requiring operation below -30°C, the 5642AB is the only option. For standard temperature range applications (-30°C to 85°C), all three parts are compatible.
