MB2065LS1W01 Equivalent & Substitute Parts

Part Overview

The MB2065LS1W01 is an obsolete SPDT pushbutton switch manufactured by NKK Switches, rated for 6A at 125V AC and 3A at 30V DC. This component features a plunger actuator with solder lug termination and panel mount rear configuration. Due to its obsolete product status, equivalent substitute parts from active manufacturers are necessary for new designs and ongoing production requirements. The substitute parts listed maintain functional compatibility through equivalent electrical ratings, circuit configuration, and mechanical mounting specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters: SPDT circuit configuration, On-On switch function, 6A AC current rating, 125V AC voltage rating, panel mount rear configuration, solder lug termination, and circular panel cutout dimensions. All substitute parts meet these core electrical and mechanical requirements. Variations in DC voltage ratings (28V-30V range), operating temperature ranges, and electrical life cycles are within acceptable tolerance for equivalent functionality. The 8161SHZQE1 operates at 120V AC (within 5V tolerance of 125V specification) and maintains 6A AC rating. The MPA106D and MPE106D both meet 125V AC and 6A AC specifications with equivalent DC ratings of 28V. All substitutes maintain ROHS3 compliance and solder lug termination required for direct circuit board integration.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance, providing long-term supply chain availability compared to the obsolete MB2065LS1W01. The MPA106D and MPE106D from TE Connectivity ALCOSWITCH Switches offer exact voltage matching at 125V AC and improved electrical life ratings of 50,000 cycles versus the original 25,000 cycles. The MPE106D provides additional splash proof ingress protection, suitable for applications requiring environmental resistance. The 8161SHZQE1 from C&K operates at 120V AC, which is within standard tolerance for 125V AC rated circuits, and maintains the original -30°C lower temperature limit. Panel cutout diameter differences (6.50mm original versus 6.35mm substitutes) require verification for mechanical fit in existing panel designs. All substitutes maintain solder lug termination for direct PCB integration without connector modifications.

Frequently Asked Questions (FAQ)

Q: Can the 8161SHZQE1 operate safely in a 125V AC circuit? A: Yes. The 8161SHZQE1 is rated for 120V AC operation. Standard industrial practice accepts 120V-rated components in 125V AC circuits, as the 5V difference falls within normal supply voltage tolerance bands.

Q: What is the impact of the 6.35mm versus 6.50mm panel cutout diameter? A: The 0.15mm difference is minimal but requires mechanical verification. If the original panel has a 6.50mm hole, the 6.35mm cutout diameter of substitute parts may result in slight lateral play. Panel modification or custom mounting brackets may be necessary for applications requiring precise mechanical alignment.

Q: Are the substitute parts suitable for DC applications? A: The original MB2065LS1W01 is rated for 3A at 30V DC. The 8161SHZQE1, MPA106D, and MPE106D are all rated for DC operation at 28V, with current ratings of 6A, 4A, and 4A respectively. These ratings exceed the original 3A DC specification, providing improved DC performance margins.

Q: What is the difference between MPA106D and MPE106D? A: Both parts are electrically identical with matching voltage, current, and temperature ratings. The primary distinction is that MPE106D includes splash proof ingress protection, making it suitable for applications exposed to moisture or liquid spray. MPA106D lacks this environmental protection feature.

Q: Do all substitutes maintain ROHS3 compliance? A: Yes. All three substitute parts—8161SHZQE1, MPA106D, and MPE106D—are ROHS3 compliant, ensuring compatibility with environmental and regulatory requirements equivalent to the original component.

Q: What is the electrical life improvement of substitute parts? A: The original MB2065LS1W01 has an electrical life of 25,000 cycles. All three substitutes offer 50,000 cycles, representing a 100% improvement in rated operational life under specified electrical conditions.
