APEM 820KMZQ Equivalent & Substitute Parts

Part Overview

The APEM 820KMZQ is a pushbutton switch with DPDT (Double Pole Double Throw) circuit configuration, rated for 6A at 125V AC and 7A at 30V DC. This component is designed for standard panel mount, rear installation applications with a plunger actuator and white cap. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when equivalent electrical and mechanical parameters allow direct replacement in the same application context, maintaining circuit functionality and panel mounting compatibility.

Key Parameters

Substitute Part Grouping Explanation

The C&K 8221SHZGE is identified as a substitute based on the following matching parameters:

• Circuit Configuration: Both parts feature DPDT switching circuits
• Switch Function: Both operate in On-Mom (momentary) mode
• Mounting Type: Both are panel mount, rear installation
• Panel Cutout Dimensions: Both use 6.35mm circular cutout
• Actuator Type: Both feature plunger actuators with white caps
• Termination Style: Both use solder lug connections
• Electrical Life: Both rated for 60,000 cycles
• RoHS Compliance: Both are ROHS3 compliant
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The 8221SHZGE operates at reduced current and voltage ratings (1A at 120V AC, 28V DC) compared to the 820KMZQ, making it suitable for lower-power applications within the same mechanical and functional framework.

Parameter Comparison

Engineering Selection Recommendations

Both the APEM 820KMZQ and C&K 8221SHZGE are active production components with ROHS3 compliance. Selection between these parts depends on application current and voltage requirements. The 820KMZQ supports higher current loads (6A AC, 7A DC) and voltage ratings (125V AC, 30V DC), making it suitable for general-purpose industrial switching applications. The 8221SHZGE is rated for lower power applications (1A AC/DC, 120V AC, 28V DC) and includes tactile feedback as an additional feature. Both parts maintain identical mechanical compatibility through matching panel cutout dimensions and mounting configurations. The 820KMZQ operates across a wider temperature range (-30°C to 85°C) compared to the 8221SHZGE (-30°C to 75°C).

Frequently Asked Questions (FAQ)

Q: Can the C&K 8221SHZGE directly replace the APEM 820KMZQ in all applications?

A: Direct replacement is limited to applications where current and voltage requirements do not exceed the 8221SHZGE ratings (1A AC/DC, 120V AC, 28V DC). Both parts share identical DPDT circuit configuration, momentary function, panel mount geometry, and solder lug termination, ensuring mechanical and electrical compatibility within these power constraints.

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

A: The primary differences are current capacity (6A vs. 1A AC), voltage ratings (125V vs. 120V AC; 30V vs. 28V DC), operating temperature range (85°C vs. 75°C maximum), and the presence of tactile feedback in the 8221SHZGE. Both maintain identical DPDT functionality, panel cutout dimensions, and electrical life ratings.

Q: Are both parts suitable for the same panel mounting applications?

A: Yes. Both parts feature identical 6.35mm circular panel cutout dimensions and rear panel mount configuration, allowing mechanical interchangeability in the same panel layout.

Q: What compliance certifications apply to both parts?

A: Both the APEM 820KMZQ and C&K 8221SHZGE are ROHS3 compliant. The 820KMZQ is REACH Unaffected, while the 8221SHZGE is REACH Affected. Both carry EAR99 ECCN classification.

Q: How do the electrical life ratings compare?

A: Both parts are rated for 60,000 electrical cycles, providing equivalent operational durability in momentary switching applications.
