Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 810KMZB are qualified based on strict alignment with the following critical parameters:

Electrical Compatibility: Circuit configuration (SPDT), switch function (On-Momentary), current rating (0.4VA AC/DC), and voltage ratings (20V AC/DC) must match exactly.

Mechanical Compatibility: Mounting type (Panel Mount, Rear), panel cutout dimensions (Circular 6.35mm Dia), termination style (Solder Lug), and actuator type (plunger-based) must be identical.

Environmental & Regulatory: Operating temperature range, RoHS compliance status, and MSL rating determine functional equivalence in specified environments.

Lifecycle Parameters: Electrical life rating (60,000 cycles minimum) ensures equivalent operational durability.

The identified substitutes—E-Switch 700SP7B10M1REH and C&K 8125SHZBE—meet all mandatory electrical and mechanical criteria, enabling direct functional replacement in applications designed for the 810KMZB.

Parameter Comparison

Engineering Selection Recommendations

APEM Inc. 810KMZB: Primary selection for applications requiring the specified electrical and mechanical parameters. Active product status with established supply chain. ROHS3 compliant and REACH unaffected. Operating temperature range extends to 85°C with 60,000 cycle electrical life rating.

E-Switch 700SP7B10M1REH: Direct functional substitute with identical electrical ratings and mechanical interface. ROHS3 compliant and REACH unaffected. Operating temperature range matches primary part at -30°C to 85°C. Electrical life rated at 50,000 cycles, which is lower than the primary part. Higher current inventory availability (1280 units) supports supply continuity.

C&K 8125SHZBE: Direct functional substitute with identical electrical ratings and mechanical interface. ROHS3 compliant with REACH affected status. Operating temperature range limited to -30°C to 75°C, restricting use in applications requiring operation above 75°C. Electrical life rated at 60,000 cycles matches primary part. Includes tactile feedback feature. Highest inventory availability (1578 units).

Selection between substitutes depends on application temperature requirements and electrical life cycle demands. The C&K 8125SHZBE is unsuitable for applications requiring sustained operation above 75°C.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 700SP7B10M1REH replace the APEM 810KMZB in all applications?

A: The E-Switch 700SP7B10M1REH provides electrical and mechanical equivalence for most applications. However, the electrical life rating of 50,000 cycles is lower than the APEM part's 60,000 cycles. Applications requiring extended cycle life should account for this difference in component selection.

Q: What is the primary difference between the C&K 8125SHZBE and the APEM 810KMZB?

A: The C&K 8125SHZBE has an operating temperature maximum of 75°C compared to the APEM part's 85°C. Applications requiring operation above 75°C must use the APEM 810KMZB or E-Switch 700SP7B10M1REH. The C&K part includes tactile feedback as an additional feature.

Q: Are all three parts panel-mount compatible with the same cutout dimensions?

A: Yes. All three parts feature identical panel cutout dimensions (Circular 6.35mm Dia) and rear panel-mount configuration, enabling direct mechanical interchange without panel modification.

Q: Do all substitute parts meet the same regulatory compliance standards?

A: All three parts are ROHS3 compliant and rated MSL 1 (Unlimited). The C&K 8125SHZBE is REACH affected, while the APEM 810KMZB and E-Switch 700SP7B10M1REH are REACH unaffected. Applications subject to REACH restrictions should confirm compliance requirements before selection.

Q: What is the solder lug termination compatibility across all three parts?

A: All three parts use identical solder lug termination style, ensuring direct electrical connection compatibility without adapter requirements or circuit board redesign.

Q: Which substitute offers the best inventory availability?

A: The C&K 8125SHZBE provides the highest current inventory at 1578 units, followed by the E-Switch 700SP7B10M1REH at 1280 units. The APEM 810KMZB maintains 846 units in stock.
