APEM Inc. 5636AB Toggle Switch SPDT 6A 125V Equivalent & Substitute Parts

Part Overview

The APEM Inc. 5636AB is a panel-mount toggle switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 6A at 125V AC and 4A at 30V DC. This switch features a standard round actuator with solder lug termination and epoxy-sealed terminals for environmental protection. The part is currently active in production status with 1115 units in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative sourcing is required for supply chain optimization, or when design flexibility permits selection from multiple qualified manufacturers while maintaining electrical and mechanical compatibility.

Primary Compatibility Criteria:

Circuit configuration: SPDT
Switch function: On-On
Mounting type: Panel Mount
Termination style: Solder Lug
Bushing thread: 1/4-40
Actuator type: Standard Round

Electrical Compatibility Criteria:

Current rating must meet or exceed 6A AC / 4A DC
Voltage rating must meet or exceed 125V AC / 30V DC
Operating temperature range must encompass -40°C to 85°C minimum

Mechanical Compatibility Criteria:

Panel cutout diameter: 6.50mm (allows 6.35mm alternatives with standard panel tolerances)

Engineering Selection Recommendations

Direct Electrical and Mechanical Equivalents (Preferred for Drop-In Replacement):

The NKK Switches M2012SD series (M2012SD1W01, M2012SD3A01, M2012SD3W01) provide identical electrical ratings (6A AC / 4A DC, 125V AC / 30V DC) and mechanical specifications (10.50mm actuator length, 6.50mm panel cutout, 1/4-40 bushing thread). However, these parts carry obsolete product status. All three variants are ROHS3 compliant and REACH unaffected, matching the primary part's compliance profile. Electrical life is reduced to 25,000 cycles compared to the 5636AB's 50,000 cycles.

Functional Equivalents with Reduced Current Rating (Conditional Substitution):

The E-Switch 100SP1T1B1M1QEH and 100SP1T1B9M1QEH, Carling Technologies 2M1-SP1-T1-B1-M1QE, TE Connectivity 4-1825136-9, and C&K 7101SHZQE, 7101SYZGE, and 7101SYZQE all provide SPDT on-on configuration with panel mount solder lug termination. These parts are rated for 5A AC/DC at 120V AC (or 125V AC for Carling), which is below the 5636AB's 6A AC rating. All substitute parts are active in production status and ROHS3 compliant.

The C&K 7000 series (7101SHZQE, 7101SYZGE, 7101SYZQE) offer extended electrical life of 100,000 cycles and are available in high inventory quantities (949 to 22,654 units). The Carling Technologies 2M1-SP1-T1-B1-M1QE matches the 5636AB's 50,000-cycle electrical life and provides IP67 ingress protection.

Compliance Considerations:

All active substitute parts maintain ROHS3 compliance and EAR99 ECCN classification. The C&K parts carry REACH Affected status, while the primary part and most other substitutes are REACH Unaffected. The TE Connectivity part shows Vendor Undefined REACH status.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100SP1T1B1M1QEH be used as a direct replacement for the 5636AB?

A: The E-Switch part provides functional equivalence for SPDT on-on switching with panel mount solder lug termination and matching bushing thread (1/4-40). However, it is rated for 5A AC/DC at 120V AC, which is below the 5636AB's 6A AC / 125V AC rating. Substitution is acceptable only if the application circuit does not require the full 6A capacity or 125V rating.

Q: What is the significance of the panel cutout diameter difference between 6.50mm and 6.35mm?

A: The 5636AB specifies a 6.50mm circular panel cutout, while most substitute parts specify 6.35mm. Standard panel tolerances typically accommodate this 0.15mm difference. Physical verification with the target panel is recommended for applications with tight mechanical tolerances.

Q: Why are the NKK Switches M2012SD parts listed as obsolete?

A: Obsolete product status indicates these parts are no longer in active production. While 1,059 to 5,271 units remain in inventory, long-term availability cannot be guaranteed. These parts should be selected only when active alternatives do not meet application requirements.

Q: How does electrical life affect part selection?

A: Electrical life specifies the number of on-off cycles the switch can withstand before performance degradation. The 5636AB is rated for 50,000 cycles. Substitutes range from 6,000 cycles (TE Connectivity) to 100,000 cycles (C&K 7000 series). Selection should align with the application's expected cycle count over its operational lifetime.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts carry ROHS3 compliance certification, matching the primary part's environmental compliance status.

Q: What is the operating temperature range consideration for substitution?

A: The 5636AB operates from -40°C to 85°C. Most substitute parts operate from -30°C to 85°C, which is a 10°C reduction at the lower temperature limit. Substitution is acceptable for applications that do not require operation below -30°C.
