MB2411S2G40 Equivalent & Substitute Parts

Part Overview

The MB2411S2G40 is a pushbutton switch manufactured by NKK Switches, featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA current rating at 28V. This component is designed for through-hole mounting in right-angle vertical orientation with a plunger actuator and epoxy sealed terminals. The product is currently obsolete, making identification of equivalent substitute parts essential for legacy system maintenance and component sourcing.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MB2411S2G40 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary operation)
• Current rating: 0.4VA (AC/DC)
• Mounting type: Through hole, right angle, vertical orientation
• Termination style: PC Pin
• Actuator type compatibility: Plunger or button actuator

Secondary Compatibility Factors:

• Voltage rating (minimum 28V AC/DC for primary part; lower ratings acceptable only if application permits)
• Operating temperature range overlap
• Electrical and mechanical life specifications
• RoHS and regulatory compliance status

The identified substitutes maintain electrical and mechanical compatibility within the constraints of the specified parameters while accounting for differences in manufacturer, packaging, and product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

MB2411A2G40 (NKK Switches)

This substitute maintains complete electrical and mechanical equivalence to the MB2411S2G40. Both components share identical circuit configuration, current rating, voltage specifications, mounting orientation, and termination style. Operating temperature range and lifecycle specifications are identical. Both parts are ROHS3 compliant and carry the same regulatory status. The primary distinction is packaging format (bulk vs. standard). This substitute is recommended as the primary alternative when the MB2411S2G40 is unavailable, as it provides direct functional replacement with no design modifications required.

8168SH9AV2BE2 (C&K)

This substitute provides functional compatibility with the following considerations: voltage rating is reduced to 20V AC/DC compared to the 28V specification of the main part. Electrical life is specified at 50,000 cycles versus 100,000 cycles for the main part. Operating temperature range is narrower (-30°C to 65°C versus -30°C to 85°C). Mechanical life is not specified. The actuator type differs (round button versus plunger for cap). This component is currently active in production. Selection of this substitute is appropriate only when application voltage requirements do not exceed 20V and operating temperature remains within the -30°C to 65°C range. The reduced electrical life specification requires evaluation against application duty cycle requirements.

Frequently Asked Questions (FAQ)

Q: Can MB2411A2G40 be used as a direct replacement for MB2411S2G40?

A: Yes. Both components are manufactured by NKK Switches within the MB2400 series and share identical electrical ratings (0.4VA at 28V AC/DC), circuit configuration (SPDT), switch function (On-Mom), mounting type (through hole, right angle, vertical), and termination style (PC Pin). Operating temperature range and lifecycle specifications are identical. The only difference is packaging format.

Q: What are the voltage limitations when using 8168SH9AV2BE2 as a substitute?

A: The 8168SH9AV2BE2 is rated for 20V AC/DC maximum, compared to 28V for the MB2411S2G40. This substitute is suitable only for applications where the operating voltage does not exceed 20V. Applications requiring 28V operation must use MB2411A2G40 or equivalent 28V-rated components.

Q: How do electrical life specifications affect component selection?

A: The MB2411S2G40 and MB2411A2G40 are rated for 100,000 electrical cycles, while the 8168SH9AV2BE2 is rated for 50,000 cycles. Applications with high switching frequency or extended operational life requirements should prioritize components with higher electrical life ratings. Verify application duty cycle against the selected component's electrical life specification.

Q: Are all three components RoHS compliant?

A: Yes. MB2411S2G40, MB2411A2G40, and 8168SH9AV2BE2 are all ROHS3 compliant. All three components meet current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of product status (Obsolete vs. Active)?

A: MB2411S2G40 and MB2411A2G40 are obsolete products no longer in active production. The 8168SH9AV2BE2 is an active product currently manufactured. For new designs or long-term sourcing requirements, active products provide better availability and supply chain stability. For legacy system maintenance, obsolete components may be sourced from inventory while supplies remain available.

Q: Does the actuator type difference between components affect mechanical compatibility?

A: The MB2411S2G40 and MB2411A2G40 feature plunger actuators, while the 8168SH9AV2BE2 features a round button actuator. Physical panel cutout dimensions and actuator engagement characteristics may differ. Verify mechanical fit and actuator clearance within the application enclosure before selecting the C&K component as a substitute.
