APEM Inc. 810KMZG Pushbutton Switch SPDT Equivalent & Substitute Parts

Part Overview

The APEM Inc. 810KMZG is a panel-mount pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 6A at 125V AC and 7A at 30V DC. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations. The 810KMZG operates with an on-momentary switch function and features a white plunger actuator with solder lug termination, suitable for standard industrial control applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 810KMZG is determined by the following critical parameters: circuit configuration (SPDT), switch function (On-Mom), mounting type (Panel Mount, Rear), panel cutout dimensions (Circular 6.35mm), termination style (Solder Lug), and electrical ratings (current and voltage). Substitute parts must maintain compatibility across these core mechanical and electrical specifications.

The identified substitute parts fall into two categories based on electrical rating alignment:

Direct Electrical Equivalent (6A Rating): The C&K 8168SHZGE2 maintains the 6A current rating and comparable voltage specifications, making it suitable for applications requiring full electrical equivalence to the 810KMZG.

Reduced Rating Substitutes: The APEM Inc. 810KMZB and C&K 8121SDZGE offer lower current and voltage ratings (0.4VA and 1A respectively) and are applicable only in applications where the load requirements do not exceed their specified electrical limits.

All substitute candidates share the same SPDT circuit, on-momentary function, panel mount configuration, 6.35mm circular cutout, and solder lug termination.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Full Electrical Equivalence): The C&K 8168SHZGE2 is the primary substitute for the obsolete 810KMZG. Both components maintain 6A current ratings and comparable AC/DC voltage specifications (120V AC / 28V DC versus 125V AC / 30V DC). The 8168SHZGE2 is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating. The operating temperature range of the 8168SHZGE2 (-30°C to 65°C) is narrower than the 810KMZG (-30°C to 85°C), requiring verification that application requirements fall within this range. Electrical life is rated at 50,000 cycles compared to 60,000 cycles for the original part.

For Reduced-Load Applications: The APEM Inc. 810KMZB and C&K 8121SDZGE are suitable only for applications where electrical load requirements do not exceed their respective ratings (0.4VA and 1A). These parts maintain the same mechanical interface and SPDT on-momentary function but are not suitable for applications requiring the full 6A capacity of the 810KMZG. The 810KMZB offers the same operating temperature range as the original part (-30°C to 85°C), while the 8121SDZGE is limited to -30°C to 75°C.

All substitute candidates maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory alignment with the original component.

Frequently Asked Questions (FAQ)

Q: Can the C&K 8168SHZGE2 be used as a direct replacement for the APEM 810KMZG? A: The 8168SHZGE2 is mechanically and electrically compatible for most applications. Both components share identical SPDT circuit configuration, on-momentary function, 6.35mm panel cutout, and solder lug termination. Electrical ratings are comparable (6A at 120V AC / 28V DC versus 6A at 125V AC / 30V DC). The primary consideration is the narrower operating temperature range of the 8168SHZGE2 (-30°C to 65°C versus -30°C to 85°C) and slightly lower electrical life rating (50,000 versus 60,000 cycles).

Q: What is the difference between the APEM 810KMZB and the C&K 8121SDZGE substitutes? A: Both parts offer reduced electrical ratings compared to the 810KMZG. The 810KMZB is rated for 0.4VA at 20V, while the 8121SDZGE is rated for 1A at 120V DC. The 810KMZB maintains the same operating temperature range as the original part (-30°C to 85°C), whereas the 8121SDZGE is limited to -30°C to 75°C. Both are suitable only for low-power applications where load requirements do not exceed their specified ratings.

Q: Are all substitute parts RoHS compliant? A: Yes, all identified substitute parts (8168SHZGE2, 810KMZB, and 8121SDZGE) are ROHS3 compliant, matching the compliance status of the original 810KMZG.

Q: What are the mechanical compatibility requirements for substitution? A: All substitute parts maintain identical mechanical specifications: panel mount rear configuration, 6.35mm circular panel cutout, and solder lug termination. These parameters ensure direct mechanical interchangeability without modification to the mounting interface or PCB layout.

Q: How do the actuator types differ among the substitute options? A: The 810KMZG features a white plunger actuator for cap mounting. The C&K 8168SHZGE2 uses a black round button actuator, the APEM 810KMZB uses a white plunger actuator, and the C&K 8121SDZGE uses a white round plunger actuator. Actuator type differences may affect user interface feel and visual appearance but do not impact electrical function or mechanical mounting.

Q: What inventory availability exists for these substitute parts? A: The C&K 8168SHZGE2 has 1,446 units in stock, the APEM 810KMZB has 846 units, and the C&K 8121SDZGE has 1,039 units available. The original 810KMZG has 783 units in stock but is classified as obsolete.
