APEM 5667AB Toggle Switch 4PDT 6A 125V Equivalent & Substitute Parts

Part Overview

The APEM 5667AB 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 operates in a Mom-Off-Mom (momentary-off-momentary) function and features epoxy-sealed solder lug terminals with a circular 6.50mm panel cutout. The product is currently active and available in bulk packaging with 1121 pieces in stock. Equivalent and substitute parts are identified when they maintain the same circuit topology, mounting configuration, and electrical performance within acceptable operational parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the APEM 5667AB is determined by the following critical parameters:

• Circuit configuration must be 4PDT
• Switch function must be Mom-Off-Mom
• Mounting type must be Panel Mount
• Termination style must be Solder Lug
• Current rating (AC) must be ≥5A at ≥120V
• Current rating (DC) must be ≥4A at ≥28V
• Panel cutout diameter must be compatible (6.35mm to 6.50mm)
• Bushing thread must be 1/4-40
• Operating temperature range must encompass or exceed -30°C to 85°C
• RoHS3 compliance required

The C&K 7405SYZQE meets these substitution criteria with equivalent electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the APEM 5667AB and C&K 7405SYZQE are active products with ROHS3 compliance. The APEM 5667AB provides a wider operating temperature range (-40°C to 85°C) compared to the C&K 7405SYZQE (-30°C to 85°C), making it suitable for applications requiring extended low-temperature performance. The C&K 7405SYZQE offers higher electrical life (40,000 cycles versus 30,000 cycles), providing extended service life in high-cycle applications. Both switches maintain equivalent circuit topology, mounting configuration, and termination style. Selection between these parts should be based on specific application requirements regarding temperature extremes and cycle life expectations.

Frequently Asked Questions (FAQ)

Q: Can the C&K 7405SYZQE directly replace the APEM 5667AB in existing designs?

A: Yes, the C&K 7405SYZQE is mechanically and electrically compatible as a substitute. Both switches feature identical 4PDT circuit configuration, Mom-Off-Mom function, panel mount design, 1/4-40 bushing thread, and solder lug termination. Panel cutout dimensions are within acceptable tolerance (6.35mm versus 6.50mm). Electrical ratings are compatible for standard applications operating within -30°C to 85°C.

Q: What are the key differences between these two switches?

A: The primary differences are: (1) Operating temperature range—APEM 5667AB operates to -40°C while C&K 7405SYZQE operates to -30°C; (2) Electrical life—C&K 7405SYZQE rated for 40,000 cycles versus APEM 5667AB at 30,000 cycles; (3) AC voltage rating—APEM 5667AB rated at 125V versus C&K 7405SYZQE at 120V; (4) Actuator material—APEM uses brass with nickel plating while C&K uses brass with chrome plating.

Q: Are both switches RoHS compliant?

A: Yes, both the APEM 5667AB and C&K 7405SYZQE are ROHS3 compliant.

Q: What panel cutout size is required for installation?

A: The APEM 5667AB requires a 6.50mm circular cutout, while the C&K 7405SYZQE requires a 6.35mm circular cutout. Both use 1/4-40 bushing thread for panel mounting. Existing panel cutouts designed for the APEM 5667AB may require slight modification to accommodate the C&K 7405SYZQE.

Q: Which switch should I select for low-temperature applications?

A: The APEM 5667AB is specified for operation down to -40°C, making it the appropriate choice for applications requiring extended low-temperature performance. The C&K 7405SYZQE is rated to -30°C.

Q: Which switch offers longer service life?

A: The C&K 7405SYZQE is rated for 40,000 electrical cycles compared to the APEM 5667AB at 30,000 cycles, providing approximately 33% longer operational life in high-cycle switching applications.
