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

Part Overview

The APEM Inc. 810KMZQ 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 operates in On-Momentary function with a white plunger actuator and solder lug termination. The 810KMZQ is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance, repairs, and new designs requiring compatible functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 810KMZQ is determined by the following critical parameters:

• Circuit Configuration: SPDT (mandatory match)
• Switch Function: On-Momentary (mandatory match)
• Mounting Type: Panel Mount, Rear (mandatory match)
• Termination Style: Solder Lug (mandatory match)
• Actuator Type: Plunger configuration (mandatory match)
• Actuator Color: White (mandatory match)
• Panel Cutout Dimensions: Circular - 6.35mm Dia (mandatory match for mechanical compatibility)
• Operating Temperature Range: -30°C to 85°C (mandatory match or better)
• RoHS Status: ROHS3 Compliant (mandatory match)
• Moisture Sensitivity Level: 1 (Unlimited) (mandatory match)

Current and voltage ratings may vary within acceptable operational limits provided the substitute part meets or exceeds the minimum requirements of the application. Electrical life specifications must be documented for each substitute.

Parameter Comparison

Engineering Selection Recommendations

700SP7B10M1QEH (E-Switch) is the primary substitute for the 810KMZQ. This part maintains full mechanical compatibility with matching panel cutout dimensions (Circular - 6.35mm Dia), identical operating temperature range (-30°C to 85°C), and equivalent electrical life (50,000 cycles). The 3A AC/DC current rating provides adequate capacity for most applications previously served by the 810KMZQ, with voltage ratings of 120V AC and 28V DC meeting standard industrial requirements. Active product status ensures ongoing availability and supply chain continuity.

8121SHZGE (C&K) serves as a secondary substitute with matching mechanical specifications and electrical life (60,000 cycles). This part is active and ROHS3 compliant. The operating temperature range extends to 75°C maximum, which is 10°C lower than the 810KMZQ specification. The 1A current rating is suitable only for low-current applications. REACH status is affected, requiring compliance verification for regulated markets.

3MN-SP7-P1-B11-M1GE (Carling Technologies) is not recommended as a direct substitute. Panel cutout dimensions are not specified, creating mechanical compatibility uncertainty. The 1A current rating significantly limits application scope compared to the 810KMZQ's 6A rating.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, ensuring regulatory and environmental compatibility with the original component.

Frequently Asked Questions (FAQ)

Q: Can the 700SP7B10M1QEH replace the 810KMZQ in all applications?

A: The 700SP7B10M1QEH is mechanically and functionally compatible with the 810KMZQ. However, the current rating difference (3A versus 6A) requires verification that the application does not exceed 3A. Voltage ratings (120V AC, 28V DC) are within acceptable industrial standards. Mechanical compatibility is confirmed by matching panel cutout dimensions.

Q: Why is the 3MN-SP7-P1-B11-M1GE not recommended?

A: The panel cutout dimensions for the 3MN-SP7-P1-B11-M1GE are not specified in the technical data. This creates uncertainty regarding mechanical fit in existing panel installations designed for the 810KMZQ's 6.35mm circular cutout. Additionally, the 1A current rating is insufficient for applications requiring the 810KMZQ's 6A capacity.

Q: What is the impact of the 8121SHZGE's lower maximum operating temperature?

A: The 8121SHZGE operates to 75°C maximum, compared to the 810KMZQ's 85°C specification. Applications operating near or above 75°C require the 700SP7B10M1QEH or continued use of the 810KMZQ if available. The 8121SHZGE is suitable for applications with maximum operating temperatures at or below 75°C.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The 700SP7B10M1QEH, 3MN-SP7-P1-B11-M1GE, and 8121SHZGE are all ROHS3 compliant, matching the 810KMZQ's regulatory status.

Q: What is the difference in electrical life between these parts?

A: The 810KMZQ and 8121SHZGE both specify 60,000 electrical cycles. The 700SP7B10M1QEH and 3MN-SP7-P1-B11-M1GE specify 50,000 cycles. For applications requiring extended cycle life, the 810KMZQ or 8121SHZGE are preferred.

Q: Does REACH status affect substitute part selection?

A: The 8121SHZGE is REACH Affected, while the 810KMZQ, 700SP7B10M1QEH, and 3MN-SP7-P1-B11-M1GE are REACH Unaffected. For applications in regulated markets requiring REACH compliance, the 700SP7B10M1QEH is the recommended substitute.
