APEM 5662AB Toggle Switch 4PDT 6A 125V Equivalent & Substitute Parts

Part Overview

The APEM 5662AB is a panel-mounted toggle switch with 4PDT (four-pole double-throw) circuit configuration, rated for 6A AC at 125V and 4A DC at 30V. This switch is designed for applications requiring momentary-on operation with epoxy-sealed solder lug terminations. The part is currently active in production with 870 units in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component substitution within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the APEM 5662AB are identified based on the following critical parameters that must align for functional equivalence:

Primary Matching Criteria:

• Circuit configuration: 4PDT
• Switch function: On-Mom (momentary operation)
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Panel cutout diameter: Within mechanical tolerance (6.35mm to 6.50mm acceptable for standard 1/4-40 bushing)
• Bushing thread: 1/4-40

Electrical Compatibility Parameters:

• AC voltage rating: Minimum 120V (5662AB rated 125V)
• AC current rating: Minimum 5A (5662AB rated 6A)
• DC voltage rating: Minimum 28V (5662AB rated 30V)
• DC current rating: Minimum 4A (5662AB rated 4A)

Environmental & Compliance Parameters:

• Operating temperature range: Must encompass or match -40°C to 85°C
• RoHS compliance: ROHS3 Compliant
• Electrical life: Minimum 30,000 cycles

The C&K 7408SYZQE meets all primary matching criteria and electrical compatibility thresholds, qualifying it as a direct substitute for the APEM 5662AB.

Parameter Comparison

Engineering Selection Recommendations

APEM 5662AB Selection Criteria:

• Applications requiring AC operation at 6A and 125V
• Operating environments with temperatures below -30°C
• Primary sourcing when inventory is available

C&K 7408SYZQE Selection Criteria:

• Applications with AC current requirements ≤5A at 120V or higher
• Applications with DC current requirements up to 5A at 28V or higher
• Operating environments with temperatures ≥-30°C
• Extended electrical life requirement (40,000 cycles vs. 30,000 cycles)
• Alternative sourcing when APEM 5662AB is unavailable

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard PCB assembly and storage protocols. The C&K 7408SYZQE is REACH Affected, while the APEM 5662AB is REACH Unaffected; this distinction may impact supply chain documentation requirements depending on end-use application and regional regulations.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7408SYZQE directly replace the APEM 5662AB in all applications?

A: The C&K 7408SYZQE is a functional substitute for applications where AC current does not exceed 5A and operating temperature remains above -30°C. Applications requiring 6A AC operation or temperatures below -30°C must use the APEM 5662AB or verify that the C&K part meets specific design margins.

Q: What is the significance of the panel cutout diameter difference (6.50mm vs. 6.35mm)?

A: Both parts use the same 1/4-40 bushing thread. The cutout diameter difference of 0.15mm falls within standard mechanical tolerance for panel-mounted switches and does not affect interchangeability in typical panel designs.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and carry MSL 1 (unlimited) moisture sensitivity ratings. The C&K 7408SYZQE is REACH Affected, while the APEM 5662AB is REACH Unaffected. Applications subject to REACH regulations should verify compliance requirements with their supply chain or regulatory team.

Q: How do the electrical life ratings compare?

A: The APEM 5662AB is rated for 30,000 electrical cycles, while the C&K 7408SYZQE is rated for 40,000 cycles. Both exceed typical industrial application requirements; the C&K part provides additional margin for high-cycle-count applications.

Q: What is the impact of the operating temperature range difference?

A: The APEM 5662AB operates from -40°C to 85°C, while the C&K 7408SYZQE operates from -30°C to 85°C. Applications requiring operation below -30°C must use the APEM 5662AB. Applications operating within -30°C to 85°C may use either part.
