M2019SS1G01 Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The M2019SS1G01 is a panel-mount toggle switch manufactured by NKK Switches with SPDT (Single Pole Double Throw) circuit configuration. This component operates at 0.4VA across 28V AC/DC with a standard round actuator and solder lug termination. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M2019SS1G01 is determined by the following critical parameters:

• Circuit Configuration: SPDT (mandatory match)
• Switch Function: On-Off-Mom (mandatory match)
• Mounting Type: Panel Mount (mandatory match)
• Termination Style: Solder Lug (mandatory match)
• Bushing Thread: 1/4-40 (mandatory match)
• Operating Temperature Range: -30°C to 85°C (mandatory match)
• Voltage Rating - DC: 28V minimum (mandatory match or exceed)
• Panel Cutout Diameter: 6.35mm or 6.50mm (compatible mechanical fit)

The substitute parts are grouped into two categories based on electrical rating compatibility:

Category A - Low Current Rating (0.4VA): 7107P3HZBE22 matches the original electrical specifications with reduced voltage rating (20V AC/DC vs. 28V AC/DC).

Category B - High Current Rating (5A): 100SP5T6B11M1QEH, 7107P4Y1ZQE, and 7107SPHZQE exceed the original current capacity (5A vs. 0.4VA) while maintaining 28V DC compatibility and all mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Equivalence (0.4VA Rating)

7107P3HZBE22 from C&K provides the closest electrical match with identical 0.4VA current rating and On-Off-Mom function. This part operates at 20V AC/DC, which is lower than the original 28V specification. Selection of this part is appropriate only when the application circuit operates at or below 20V DC. The part is ROHS3 compliant and currently in active production status with 1,119 units in stock.

For Enhanced Current Capacity (5A Rating)

100SP5T6B11M1QEH (E-Switch), 7107P4Y1ZQE (C&K), and 7107SPHZQE (C&K) all provide 5A current capacity, representing a 12.5x increase over the original specification. These parts maintain 28V DC compatibility and are suitable for applications requiring higher switching capacity.

• 100SP5T6B11M1QEH is ROHS3 compliant with active product status and 761 units in stock.
• 7107SPHZQE is ROHS3 compliant with active product status and 985 units in stock.
• 7107P4Y1ZQE is RoHS non-compliant and should be avoided in applications requiring regulatory compliance.

All substitute parts maintain the required 1/4-40 bushing thread and solder lug termination. Panel cutout diameter differences (6.35mm vs. 6.50mm) are mechanically compatible within standard panel mounting tolerances.

Frequently Asked Questions (FAQ)

Q: Can I use a 5A-rated substitute in place of the 0.4VA original part?

A: Yes. The 5A-rated substitutes (100SP5T6B11M1QEH, 7107SPHZQE, 7107P4Y1ZQE) are electrically backward-compatible with the original 0.4VA application. Higher current capacity does not degrade performance in lower-current circuits. However, verify that the application circuit operates at 28V DC or lower to ensure voltage compatibility.

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

A: The 0.15mm difference is within standard mechanical tolerances for panel-mount switches. Existing panel cutouts designed for the M2019SS1G01 (6.50mm) will accommodate substitute parts with 6.35mm diameter specifications. No panel modification is required.

Q: Why does 7107P3HZBE22 have a lower voltage rating (20V) than the original?

A: The 7107P3HZBE22 is rated for 20V AC/DC maximum, compared to the original 28V specification. This part is suitable only for applications operating at 20V or below. For applications requiring 28V operation, select 100SP5T6B11M1QEH, 7107P4Y1ZQE, or 7107SPHZQE.

Q: What is the significance of RoHS compliance status in substitute selection?

A: ROHS3 compliance indicates the part meets European Union Restriction of Hazardous Substances regulations. For applications subject to regulatory requirements or customer specifications mandating RoHS compliance, select 100SP5T6B11M1QEH, 7107P3HZBE22, or 7107SPHZQE. Avoid 7107P4Y1ZQE in regulated applications.

Q: How do electrical life ratings compare between the original and substitutes?

A: The M2019SS1G01 is rated for 50,000 electrical cycles, while all substitute parts are rated for 40,000 cycles. For applications requiring extended cycle life, the original part specification is superior. However, 40,000 cycles remains suitable for most industrial control applications.

Q: Are all substitutes available in the same packaging as the original?

A: No. The original M2019SS1G01 is packaged in standard format. Substitute parts are available in Bulk (100SP5T6B11M1QEH, 7107P3HZBE22, 7107P4Y1ZQE) or Tray (7107SPHZQE) packaging. Verify packaging requirements for your procurement and assembly processes.
