Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011LS4W01-CH/AT507M is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom (Momentary)
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• AC voltage rating: 125V minimum
• AC current rating: 6A minimum
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation Parameters:

• DC current rating: Substitute must meet or exceed 3A
• DC voltage rating: Substitute must meet or exceed 30V
• Panel cutout diameter: Tolerance within mechanical design constraints
• Operating temperature range: Substitute may have narrower range if application requirements are met
• Electrical life: Substitute may exceed specified cycles
• Actuator type: May differ if mechanical interface compatibility is maintained

The substitute parts MPA106F and MPE106F from TE Connectivity ALCOSWITCH Switches meet all mandatory matching parameters and allowable variation criteria, qualifying them as direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

Both MPA106F and MPE106F are active production components from TE Connectivity ALCOSWITCH Switches and serve as functional equivalents to the obsolete MB2011LS4W01-CH/AT507M.

MPA106F Selection Criteria:

• Suitable for standard applications where ingress protection is not a design requirement
• Meets all electrical and mechanical specifications of the original component
• ROHS3 compliant; REACH status vendor undefined
• Higher electrical life rating (50,000 cycles) provides extended operational durability

MPE106F Selection Criteria:

• Recommended for applications requiring enhanced environmental protection
• Includes splash proof ingress protection rating
• ROHS3 compliant; REACH affected status
• Higher electrical life rating (50,000 cycles) provides extended operational durability

Panel Cutout Consideration: The substitute parts feature a 6.35mm panel cutout diameter compared to the original 6.50mm specification. Panel mounting compatibility must be evaluated based on existing mechanical tolerances and mounting hole dimensions in the target application.

Temperature Range Consideration: The substitute parts operate within -20°C to 80°C, which is narrower than the original -30°C to 85°C range. Applications requiring operation below -20°C or above 80°C must be assessed for compatibility.

Frequently Asked Questions (FAQ)

Q: Can MPA106F and MPE106F be used interchangeably with MB2011LS4W01-CH/AT507M?

A: Both substitute parts meet the mandatory electrical and mechanical parameters. The primary difference is ingress protection: MPE106F includes splash proof rating while MPA106F does not. Selection depends on environmental exposure requirements of the specific application.

Q: What is the impact of the 6.35mm versus 6.50mm panel cutout diameter difference?

A: The 0.15mm difference requires mechanical evaluation of the target panel mounting interface. If the original design includes tolerance allowance, the substitute parts are compatible. If the mounting hole is precisely machined to 6.50mm, panel modification may be necessary.

Q: Are the substitute parts suitable for DC applications?

A: Yes. Both MPA106F and MPE106F are rated for 4A DC at 28V, exceeding the original component's 3A DC at 30V specification. DC applications are supported within these electrical parameters.

Q: What is the significance of the higher electrical life rating in the substitute parts?

A: The substitute parts are rated for 50,000 electrical cycles compared to the original 25,000 cycles. This represents a 2x improvement in electrical endurance and indicates enhanced reliability for high-cycle applications.

Q: Does the narrower operating temperature range of the substitute parts affect compatibility?

A: The substitute parts operate from -20°C to 80°C versus the original -30°C to 85°C. Applications operating within the -20°C to 80°C window are fully compatible. Applications requiring extended temperature operation must be reassessed.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both MPA106F and MPE106F are ROHS3 compliant, matching the compliance status of the original component.

Q: What is the difference in REACH status between the two substitute parts?

A: MPA106F has vendor undefined REACH status, while MPE106F is REACH affected. Applications subject to REACH regulatory requirements should specify MPE106F or confirm MPA106F compliance with the supplier.
