APEM Inc. 5669AB Toggle Switch 4PDT Equivalent & Substitute Parts

Part Overview

The APEM Inc. 5669AB is a 4PDT panel mount 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 epoxy sealed terminals for enhanced durability. The product is active and ROHS3 compliant, designed for applications requiring reliable on-off-on switching functionality. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit component flexibility within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 5669AB are identified based on the following critical parameters that determine functional compatibility:

Primary Compatibility Criteria:

• Circuit configuration: 4PDT
• Switch function: On-Off-On
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Bushing thread: 1/4-40
• Panel cutout diameter: Circular configuration

Electrical Parameter Tolerance: Substitute parts must maintain current and voltage ratings sufficient for the application. The 5669AB operates at 6A/125V AC and 4A/30V DC. Substitute parts rated at 5A/120V AC and 5A/28V DC represent acceptable alternatives for applications operating within these lower specifications.

Mechanical Parameter Tolerance: Actuator length variation (10.50mm nominal) within ±0.26mm and panel cutout diameter variation (6.35mm to 6.50mm) are acceptable for panel mount applications with standard bushing configurations.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing and storage requirements.

Parameter Comparison

Engineering Selection Recommendations

E-Switch 1004P3T1B1M1QEH: This substitute maintains full compatibility with the 5669AB across all mechanical parameters and circuit configuration. The part is ROHS3 compliant and REACH unaffected, matching the regulatory status of the primary part. The 5A/120V AC rating is suitable for applications operating below the 5669AB maximum specification. Electrical life of 40,000 cycles exceeds the primary part specification. Operating temperature range of -30°C to 85°C is acceptable for applications not requiring the extended -40°C lower limit.

C&K 7403SYZQE: This substitute provides identical circuit configuration and mechanical compatibility with the 5669AB. The part is ROHS3 compliant but carries REACH affected status, requiring verification against specific application regulatory requirements. The 5A/120V AC rating and 40,000 cycle electrical life match the E-Switch alternative. Operating temperature range of -30°C to 85°C applies the same limitation as the E-Switch option.

Both substitute parts are suitable for applications where the 5669AB is unavailable, provided that operating conditions remain within the specified electrical and temperature parameters of the substitute part selected.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1004P3T1B1M1QEH directly replace the APEM 5669AB? A: Yes, for applications operating at or below 5A/120V AC. The 4PDT circuit configuration, on-off-on function, panel mount design, solder lug termination, and 1/4-40 bushing thread are identical. Panel cutout diameter difference (6.35mm vs 6.50mm) is within acceptable tolerance for standard panel mount applications.

Q: What is the impact of the lower current rating on the substitute parts? A: The substitute parts are rated at 5A AC/DC compared to the 5669AB at 6A AC/4A DC. Applications requiring the full 6A AC specification must use the primary part. Applications operating at 5A or below can use either substitute without derating.

Q: Are there temperature range limitations with the substitute parts? A: Both substitute parts operate from -30°C to 85°C, compared to the 5669AB range of -40°C to 85°C. Applications requiring operation below -30°C must use the primary part.

Q: What is the difference in REACH compliance status? A: The APEM 5669AB and E-Switch 1004P3T1B1M1QEH are REACH unaffected. The C&K 7403SYZQE is REACH affected. Applications subject to REACH regulations should verify compliance requirements before selecting the C&K part.

Q: Do the substitute parts have longer electrical life? A: Yes. Both substitute parts are rated for 40,000 cycles compared to 30,000 cycles for the 5669AB, providing extended operational life in high-cycle applications.

Q: Are panel cutout modifications required for installation? A: The 5669AB requires a 6.50mm diameter cutout. The substitute parts require 6.35mm diameter cutouts. Existing panels designed for the 5669AB may require modification for substitute part installation.
