MR210C2LBR Equivalent & Substitute Parts

Part Overview

The MR210C2LBR is a DPST rocker switch manufactured by APEM Inc., rated for 10A at 125V AC with panel mount, snap-in installation. The switch features a concave red illuminated actuator with neon red illumination and quick connect 0.187" termination. This component is Active status and ROHS3 compliant with 10,000 electrical life cycles.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the allowed parameter ranges for this product category. The E-Switch R1973 series provides functionally compatible alternatives with comparable panel cutout dimensions, termination style, and circuit configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

• Circuit Configuration: All substitutes maintain DPST configuration
• Voltage Rating: All substitutes rated for 125V AC operation
• Mounting Type: All substitutes use panel mount, snap-in installation
• Termination Style: All substitutes use quick connect 0.187" (4.7mm) terminals
• Panel Cutout Dimensions: Substitute parts use 19.20mm x 12.80mm (0.10mm variance in height is within mechanical tolerance)
• Current Rating: Substitute parts rated at 9A AC (1A reduction from main part)
• Compliance: All substitutes are ROHS3 compliant with MSL 1 rating

The E-Switch R1973 series substitutes are grouped by actuator color and illumination type, as these are cosmetic and functional variations that do not affect electrical compatibility within the 125V AC, DPST circuit topology.

Parameter Comparison

Engineering Selection Recommendations

All listed E-Switch R1973 series parts maintain Active product status and ROHS3 compliance equivalent to the MR210C2LBR. The primary electrical difference is the 9A current rating versus the 10A rating of the main part. Selection of substitute parts should account for actual circuit load requirements.

Substitute parts without illumination (R1973BBLKBLKAF0, R1973BBLKBLKEF0, R1973BBLKBLKFF0, R1973BBLKBLKGF0) are suitable for applications where indicator function is not required. These parts provide the lowest cost alternative while maintaining full electrical and mechanical compatibility.

Illuminated variants (R1973BBLKGILFF1, R1973BBLKGILIF1, R1973BBLKGILIF2, R1973BBLKRILFF3, R1973BBLKYILEF3) are available with different illumination types and voltages. Selection depends on control circuit voltage availability: neon illumination variants operate at 125 VAC or 250 VAC, while incandescent variants require 12 VDC supply.

The operating temperature range of substitute parts (-30°C ~ 65°C) is narrower than the main part (-20°C ~ 80°C). Applications requiring operation above 65°C or below -30°C should retain the MR210C2LBR.

Frequently Asked Questions (FAQ)

Q: Can R1973 series switches directly replace the MR210C2LBR in all applications?

A: R1973 series switches are mechanically and electrically compatible for DPST 125V AC circuits. The 9A current rating is the primary consideration. If your circuit load exceeds 9A, the MR210C2LBR must be retained. Panel cutout dimensions are within mechanical tolerance (0.10mm variance).

Q: What is the difference between illuminated and non-illuminated R1973 variants?

A: Non-illuminated variants (BLKBLK series) contain no indicator function and require no external illumination voltage. Illuminated variants include neon (GIL series at 125 VAC or 250 VAC) or incandescent (RIL or YIL series at 12 VDC) light sources. Selection depends on whether status indication is required and what voltage is available in your control circuit.

Q: Are there temperature limitations when using R1973 substitutes?

A: Yes. R1973 series parts operate from -30°C to 65°C, while the MR210C2LBR operates from -20°C to 80°C. If your application requires operation above 65°C or below -30°C, the MR210C2LBR is required.

Q: What does the 0.10mm difference in panel cutout height mean for installation?

A: The MR210C2LBR requires a 19.20mm x 12.90mm rectangular cutout, while R1973 parts require 19.20mm x 12.80mm. This 0.10mm difference in the vertical dimension is within standard mechanical tolerance for panel fabrication and does not affect snap-in installation.

Q: Do all substitute parts have the same electrical life rating?

A: Yes. All listed substitutes maintain 10,000 electrical life cycles, matching the MR210C2LBR specification. However, R1973 series parts specify 30,000 mechanical life cycles, which exceeds the main part specification.

Q: What packaging is available for substitute parts?

A: All E-Switch R1973 series substitutes are supplied in Bulk packaging. The MR210C2LBR is supplied with standard packaging notation.
