Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the MB2011SB3G03-CE is determined by the following critical electrical and mechanical parameters:

• Circuit configuration (SPDT)
• Switch function (On-Momentary)
• Current and voltage ratings (0.4VA at 28V AC/DC)
• Mounting type (Panel Mount, Rear)
• Actuator type and color (Round Button, Yellow)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular 12.50mm Dia)
• Environmental rating (IP67)
• Operating temperature range (-30°C to 85°C)
• Mechanical and electrical life (50,000 cycles minimum)

The identified substitute part MBN15SB3G03-CE is classified as a Large Bushing Miniature Pushbutton Switch from NKK Switches with Active product status. Substitution eligibility is based on matching the above parameters within acceptable engineering tolerances for the application.

Parameter Comparison

Engineering Selection Recommendations

The MB2011SB3G03-CE is an obsolete component. The substitute part MBN15SB3G03-CE is manufactured by the same supplier (NKK Switches) and carries Active product status, indicating current availability and ongoing manufacturer support.

Selection of MBN15SB3G03-CE as a substitute should be based on verification that the unspecified electrical and mechanical parameters match the requirements of the original application. The main part is ROHS3 compliant; compliance status of the substitute part should be confirmed with the manufacturer or distributor before final selection.

Frequently Asked Questions (FAQ)

Q: Why is the MB2011SB3G03-CE being phased out? A: The MB2011SB3G03-CE is classified as obsolete. NKK Switches has discontinued this model, making substitute parts necessary for ongoing system support and component replacement.

Q: What makes MBN15SB3G03-CE a valid substitute? A: Both parts are manufactured by NKK Switches and share the same base designation suffix (SB3G03-CE). The substitute is currently in Active status with documented inventory availability.

Q: Are the electrical ratings identical between the main part and substitute? A: The main part is rated for 0.4VA at 28V AC/DC with SPDT configuration and On-Momentary function. Complete electrical specifications for the substitute part should be obtained from the manufacturer datasheet to confirm compatibility with your specific application requirements.

Q: What is the significance of the panel cutout dimension (12.50mm Dia)? A: This circular dimension specifies the mechanical mounting hole required for panel installation. Any substitute part must accommodate this same cutout size to ensure proper mechanical fit in existing enclosures.

Q: Does the substitute part maintain the same environmental rating? A: The main part features IP67 ingress protection (dust tight, waterproof). Environmental specifications for the substitute should be verified against application requirements.

Q: Are both parts RoHS compliant? A: The MB2011SB3G03-CE is ROHS3 compliant. RoHS compliance status for MBN15SB3G03-CE should be confirmed with the manufacturer or distributor.
