Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LS1G02 is determined by strict equivalence across the following critical parameters:

Circuit configuration: SPDT
Current rating: 0.4VA (AC/DC)
Voltage rating: 28V AC and 28V DC
Mounting type: Panel Mount, Rear
Actuator type: Plunger for Cap
Switch function: On-Mom
Mechanical life: 100,000 Cycles
Electrical life: 50,000 Cycles
RoHS compliance: ROHS3 Compliant

The EB2011G qualifies as a substitute part based on matching all critical electrical and mechanical parameters. Variations in termination style (Quick Connect vs. Solder Lug), panel cutout dimensions (6.50mm vs. 6.35mm), and operating temperature range represent design trade-offs that must be evaluated within specific application contexts.

Engineering Selection Recommendations

The EB2011G represents the primary substitute for the obsolete MB2011LS1G02, offering active product status with full ROHS3 compliance. Both components share identical electrical specifications (0.4VA at 28V AC/DC) and mechanical performance characteristics (100,000 mechanical cycles, 50,000 electrical cycles).

Selection of EB2011G requires evaluation of three design considerations:

Termination compatibility: The EB2011G uses Solder Lug termination versus Quick Connect on the original part. Circuit board layout and assembly processes must accommodate this difference.
Panel cutout tolerance: The EB2011G panel cutout dimension (6.35mm) is 0.15mm smaller than the MB2011LS1G02 (6.50mm). Existing panel mounting holes may require verification or modification.
Operating temperature envelope: The EB2011G operates within -10°C to 70°C versus the original -30°C to 85°C range. Applications requiring extended temperature operation must confirm compatibility with the reduced envelope.

The active product status of EB2011G ensures ongoing availability and supply chain continuity compared to the obsolete MB2011LS1G02.

Frequently Asked Questions (FAQ)

Q: Can EB2011G be used as a direct replacement for MB2011LS1G02 in all applications?

A: EB2011G matches all critical electrical and mechanical parameters. However, termination style differences (Solder Lug vs. Quick Connect) and panel cutout dimensions require circuit design and mechanical layout verification before implementation.

Q: What is the primary difference between MB2011LS1G02 and EB2011G?

A: The primary differences are termination style, panel cutout diameter, and operating temperature range. Both components provide identical electrical performance at 0.4VA, 28V AC/DC with SPDT switching function.

Q: Why is the operating temperature range different between these parts?

A: The EB2011G operates within -10°C to 70°C while the MB2011LS1G02 operates within -30°C to 85°C. Applications requiring operation outside the EB2011G temperature envelope must identify alternative solutions.

Q: Are both parts RoHS compliant?

A: Yes, both MB2011LS1G02 and EB2011G are ROHS3 compliant and REACH unaffected.

Q: What packaging is available for EB2011G?

A: EB2011G is supplied in Bulk packaging, whereas MB2011LS1G02 was supplied with standard packaging.

Q: How do the panel cutout dimensions affect installation?

A: The EB2011G requires a 6.35mm circular cutout versus 6.50mm for the MB2011LS1G02. Existing panel holes designed for the original part may require enlargement or modification for proper fit.
