Engineering Selection Recommendations
All substitute parts listed are active products with current manufacturer support, addressing the obsolescence of the M2015SS1W01.
For applications requiring exact AC current rating match (6A at 125V AC), select either A126S1YZQ or MTA106F. Both maintain the 6A AC specification and are actively manufactured.
For applications where 5A AC rating is acceptable, 100SP2T1B1M1QEH, 2M1-SP2-T1-B1-M1QE, and 7108SYZQE provide viable alternatives with enhanced electrical life ratings (40,000 to 50,000 cycles versus 25,000 cycles for the original part).
The 2M1-SP2-T1-B1-M1QE offers IP67 ingress protection, providing additional environmental sealing not present in the original M2015SS1W01.
For solder lug termination compatibility, avoid A126S1YZQ, which uses wire wrap termination. All other substitutes use solder lug termination matching the original part.
Panel cutout diameter varies slightly across substitutes (6.35mm to 6.50mm). Verify panel hole dimensions before final selection.
MTA106F operates within a narrower temperature range (-20°C to 80°C) compared to the original specification (-30°C to 85°C). Confirm application temperature requirements before selection.
Frequently Asked Questions (FAQ)
Q: Can I use a substitute part with 5A AC rating in place of the 6A AC rated M2015SS1W01?
A: Substitution depends on actual circuit current requirements. If the application draws ≤5A AC, a 5A-rated substitute is acceptable. If the application requires 6A AC capability, select A126S1YZQ or MTA106F to maintain the original current rating.
Q: What is the significance of the panel cutout diameter difference?
A: The M2015SS1W01 requires a 6.50mm diameter hole. Most substitutes require 6.35mm or 6.40mm holes. Existing panel cutouts may require modification or use of adapter bushings for proper fit.
Q: Does the termination style affect substitution eligibility?
A: Yes. The M2015SS1W01 uses solder lug termination. A126S1YZQ uses wire wrap termination, requiring different circuit board connection methods. For direct replacement without rework, select substitutes with solder lug termination.
Q: Why do substitute parts have higher electrical life ratings?
A: Substitute parts represent current manufacturing technology with improved mechanical design and materials. Higher electrical life ratings (40,000 to 60,000 cycles) reflect modern switch durability standards compared to the obsolete M2015SS1W01 (25,000 cycles).
Q: Is RoHS compliance maintained across all substitutes?
A: All substitutes maintain RoHS3 compliance or equivalent RoHS compliance status, ensuring regulatory alignment with the original part.
Q: Can I use MTA106F if my application operates below -20°C?
A: No. MTA106F operates from -20°C to 80°C. If the application requires operation at -30°C, select 100SP2T1B1M1QEH, 2M1-SP2-T1-B1-M1QE, or 7108SYZQE, which all support -30°C minimum temperature.
Q: What advantage does the 2M1-SP2-T1-B1-M1QE offer over other substitutes?
A: The 2M1-SP2-T1-B1-M1QE provides IP67 ingress protection (dust tight, waterproof), making it suitable for applications requiring environmental sealing. Other substitutes do not specify ingress protection ratings.
