Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MB2011SS1W01-CH is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary operation)
• Current rating: Minimum 6A AC capability
• Voltage rating: Minimum 125V AC and 30V DC
• Mounting type: Panel Mount, Rear
• Termination style: Solder Lug
• Panel cutout dimensions: Circular configuration compatible with 6.50mm nominal diameter

Substitute parts identified:

MBN15SS1W01-CH (NKK Switches) - Manufacturer recommended equivalent with active product status.

MPA106F and MPE106F (TE Connectivity ALCOSWITCH Switches) - Similar SPDT pushbutton switches meeting core electrical and mechanical parameters. Both parts feature active product status and maintain SPDT circuit configuration with On-Mom function, 6A AC current rating, and 125V AC voltage rating. Panel cutout dimensions are 6.35mm, representing a minor dimensional variation from the original 6.50mm specification.

Parameter Comparison

Engineering Selection Recommendations

MBN15SS1W01-CH is the primary recommended substitute. This part is manufactured by NKK Switches, the original equipment manufacturer, and carries active product status. It maintains electrical and mechanical compatibility with the MB2011SS1W01-CH and is ROHS3 compliant.

MPA106F and MPE106F are secondary alternatives from TE Connectivity ALCOSWITCH Switches. Both parts are active products with ROHS3 compliance. These switches meet the core electrical requirements (6A AC, 125V AC) and maintain SPDT On-Mom functionality. The panel cutout dimension of 6.35mm represents a 0.15mm reduction from the original 6.50mm specification and must be evaluated for mechanical fit in existing panel designs. MPE106F provides splash proof ingress protection, which may offer additional environmental robustness depending on application requirements.

All substitute parts maintain solder lug termination and panel mount rear configuration, ensuring compatibility with existing PCB and panel assembly designs.

Frequently Asked Questions (FAQ)

Q: Can MPA106F or MPE106F be used as direct replacements for MB2011SS1W01-CH?

A: Both parts meet the core electrical specifications (SPDT circuit, 6A AC, 125V AC, On-Mom function, solder lug termination). The panel cutout dimension difference (6.35mm vs. 6.50mm) requires mechanical evaluation. If the original panel cutout is 6.50mm, the 6.35mm diameter of the substitute parts will fit with clearance. Verify panel mounting compatibility before implementation.

Q: What is the difference between MPA106F and MPE106F?

A: Both parts share identical electrical ratings and circuit configuration. MPE106F includes splash proof ingress protection, while MPA106F does not specify ingress protection. Selection depends on environmental exposure requirements of the application.

Q: Why is MBN15SS1W01-CH recommended over the TE Connectivity alternatives?

A: MBN15SS1W01-CH is the manufacturer-recommended equivalent from NKK Switches, the original equipment manufacturer. This ensures design continuity and maintains consistency with the original component family. The TE Connectivity parts are viable alternatives when MBN15SS1W01-CH is unavailable.

Q: Are there temperature range differences between the original part and substitutes?

A: The MB2011SS1W01-CH operates from -30°C to 85°C. MPA106F and MPE106F operate from -20°C to 80°C. If the application requires operation below -20°C or above 80°C, the original part or MBN15SS1W01-CH must be used.

Q: What is the electrical life difference between these parts?

A: MB2011SS1W01-CH is rated for 25,000 electrical cycles. MPA106F and MPE106F are rated for 50,000 electrical cycles, providing extended operational life in high-cycle applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. MB2011SS1W01-CH, MBN15SS1W01-CH, MPA106F, and MPE106F are all ROHS3 compliant.
