APEM 5248AB Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The APEM 5248AB is an active production toggle switch featuring DPDT (Double Pole Double Throw) circuitry with panel mount configuration. This component is designed for On-Off-Mom switching applications requiring 6A AC at 125V or 4A DC at 30V. The part is actively manufactured and stocked, with 694 units available in bulk packaging. Equivalent and substitute parts are identified when electrical ratings, mechanical interfaces, and functional characteristics align within acceptable tolerances for the intended application.

Key Parameters

Substitute Part Grouping Explanation

The C&K 7207SYCQE qualifies as a substitute for the APEM 5248AB based on the following alignment of critical parameters:

Matching Criteria:

• Circuit configuration: Both DPDT
• Switch function: Both On-Off-Mom
• Mounting interface: Both panel mount with 1/4-40 bushing thread
• Termination: Both PC Pin
• Panel cutout diameter: 6.35mm (C&K) vs 6.50mm (APEM) — within mechanical tolerance for standard panel cutout sizing
• Electrical life: 40,000 cycles (C&K) vs 50,000 cycles (APEM) — acceptable for equivalent duty applications
• Compliance: Both ROHS3 compliant and EAR99 classified

Functional Equivalence: The 7207SYCQE operates at 5A AC/DC at 120V AC and 28V DC, which represents a marginal reduction in current capacity (5A vs 6A AC) and voltage rating (120V vs 125V AC; 28V vs 30V DC). This substitution is valid for applications where the load does not exceed the C&K part's electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (APEM 5248AB): Select the APEM 5248AB for applications requiring the full specified current capacity of 6A AC at 125V or 4A DC at 30V. This part is actively produced, ROHS3 compliant, and rated for 50,000 electrical cycles. The extended operating temperature range (-40°C to 85°C) accommodates wider environmental conditions.

Substitute Selection (C&K 7207SYCQE): The C&K 7207SYCQE is suitable as a substitute when application requirements do not exceed 5A AC at 120V or 5A DC at 28V. Both parts are ROHS3 compliant and EAR99 classified. The C&K part operates within a narrower temperature range (-30°C to 85°C) and provides 40,000 electrical cycles. Packaging differs: APEM is supplied in bulk; C&K is supplied in trays.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7207SYCQE directly replace the APEM 5248AB in all applications?

A: No. The C&K part has lower current and voltage ratings (5A AC @ 120V vs 6A AC @ 125V). Substitution is valid only when the application load does not exceed the C&K specifications. Panel cutout diameter tolerance (6.35mm vs 6.50mm) must be verified for the specific panel design.

Q: What is the impact of the 10,000-cycle difference in electrical life?

A: The APEM part is rated for 50,000 cycles; the C&K part for 40,000 cycles. For applications with high switching frequency, the APEM part provides extended service life. For standard-duty applications, the C&K part meets functional requirements.

Q: Are both parts RoHS compliant?

A: Yes. Both the APEM 5248AB and C&K 7207SYCQE are ROHS3 compliant. The C&K part is REACH Affected; the APEM part is REACH Unaffected.

Q: Does packaging affect substitution eligibility?

A: Packaging (bulk vs tray) does not affect electrical or mechanical compatibility. It impacts procurement, storage, and handling logistics only.

Q: What is the temperature operating range difference?

A: The APEM 5248AB operates from -40°C to 85°C; the C&K 7207SYCQE from -30°C to 85°C. For applications below -30°C, only the APEM part is suitable.

Q: Are the panel mount interfaces identical?

A: Both parts use 1/4-40 bushing thread and PC Pin termination. Panel cutout diameter differs slightly (6.50mm APEM vs 6.35mm C&K). Standard panel cutout tolerances typically accommodate both sizes, but verification is required for precision panel designs.
