APEM 5644THAB SP3T Toggle Switch Equivalent & Substitute Parts

Part Overview

The APEM 5644THAB is a panel-mounted SP3T toggle switch rated for 6A at 125V AC and 4A at 30V DC. This switch features a standard round actuator with solder lug termination and operates across -40°C to 85°C. The product is active and ROHS3 compliant. Substitute parts are identified for applications requiring equivalent SP3T switching functionality with comparable electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APEM 5644THAB are qualified based on the following criteria:

Primary Compatibility Parameters:

• Circuit configuration: SP3T
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Bushing thread: 1/4-40
• Switch function: On-On-On

Electrical Compatibility Parameters:

• AC voltage rating: minimum 120V (substitute parts rated 120V AC are acceptable for 125V AC applications)
• AC current rating: minimum 5A (substitute parts rated 5A AC are acceptable for 6A AC applications within derating guidelines)
• DC voltage rating: minimum 28V (substitute parts rated 28V DC are acceptable for 30V DC applications)
• DC current rating: 5A (substitute parts rated 5A AC/DC are acceptable)

Mechanical Compatibility Parameters:

• Panel cutout diameter: 6.35mm (within tolerance of 6.50mm specification)
• Actuator type: Standard Round
• Actuator length: 10.41mm to 10.67mm (within acceptable range of 10.50mm)

The identified substitutes meet these criteria and are therefore electrically and mechanically compatible with the APEM 5644THAB.

Parameter Comparison

Engineering Selection Recommendations

APEM 5644THAB remains the primary choice for applications requiring the full 6A AC current rating and -40°C lower operating temperature limit. This part is REACH Unaffected and ROHS3 compliant.

E-Switch 100DP6T1B1M1QEH is suitable for applications where 5A AC current rating is acceptable and operating temperature does not fall below -30°C. This substitute provides ROHS3 compliance and REACH Unaffected status, matching the regulatory profile of the main part.

C&K 7211SYZQE is suitable for applications where 5A AC current rating is acceptable and operating temperature does not fall below -30°C. This substitute provides ROHS3 compliance but carries REACH Affected status, requiring evaluation against project-specific regulatory requirements.

All three parts share identical circuit configuration, mounting type, termination style, and bushing thread specifications, ensuring mechanical and electrical interchangeability within the stated parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP6T1B1M1QEH replace the APEM 5644THAB in all applications?

A: The E-Switch substitute is compatible where the application current requirement does not exceed 5A AC and the minimum operating temperature remains above -30°C. The APEM part is required for applications demanding 6A AC or operating below -30°C.

Q: What is the difference in panel cutout diameter between the main part and substitutes?

A: The APEM 5644THAB specifies a 6.50mm circular cutout, while both substitutes specify 6.35mm. Both bushing threads are 1/4-40, and the mechanical mounting interface remains compatible.

Q: Are all three parts ROHS3 compliant?

A: Yes. The APEM 5644THAB, E-Switch 100DP6T1B1M1QEH, and C&K 7211SYZQE are all ROHS3 compliant.

Q: What is the significance of REACH Affected status for the C&K 7211SYZQE?

A: REACH Affected status indicates the part contains substances of concern under REACH regulations. Applications subject to REACH requirements must evaluate this status against project compliance obligations. The APEM and E-Switch alternatives carry REACH Unaffected status.

Q: How do electrical life ratings compare?

A: The APEM 5644THAB is rated for 50,000 cycles, while both E-Switch and C&K substitutes are rated for 40,000 cycles. Applications requiring extended cycle life should specify the APEM part.

Q: Are the actuator lengths interchangeable?

A: Actuator lengths are 10.50mm (APEM), 10.41mm (E-Switch), and 10.67mm (C&K). These variations fall within acceptable mechanical tolerance for panel-mounted toggle switches with identical bushing threads and are functionally interchangeable.
