RH110C2LBR Rocker Switch SPST 20A 125V - Equivalent & Substitute Parts

Part Overview

The RH110C2LBR is an illuminated rocker switch manufactured by APEM Inc., designed for panel-mount, snap-in applications requiring single-pole, single-throw (SPST) switching functionality. This switch operates at 20A (AC) 125V with a red neon illuminated concave actuator and quick-connect 0.250" (6.3mm) termination. The product is currently active in production with 888 units in stock.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits operation within relaxed electrical parameters while maintaining mechanical compatibility and functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RH110C2LBR with the TRG22F2BBRLN is permissible based on the following alignment of critical parameters:

Mechanical Compatibility:

• Both switches feature panel mount, snap-in installation
• Both utilize quick-connect 0.250" (6.3mm) termination
• Panel cutout dimensions are functionally equivalent (30.00mm x 11.00mm vs. 30.20mm x 11.00mm)
• Both employ concave (curved) illuminated red actuators with neon red illumination

Electrical Compatibility:

• Both operate at 125V AC
• Both are SPST on-off switches
• The TRG22F2BBRLN is rated for 16A AC, which is lower than the RH110C2LBR's 20A rating but remains suitable for applications not requiring the full 20A capacity

Regulatory Compliance:

• Both are ROHS3 compliant
• Both are REACH unaffected
• Both share identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications

Operational Differences:

• Operating temperature range differs: RH110C2LBR operates -20°C to 85°C; TRG22F2BBRLN operates -20°C to 65°C
• Electrical life differs: RH110C2LBR rated for 10,000 cycles; TRG22F2BBRLN rated for 6,000 cycles
• Mechanical life is specified only for TRG22F2BBRLN (10,000 cycles)

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (RH110C2LBR): The RH110C2LBR remains the preferred component for applications requiring the full 20A AC capacity and extended operating temperature range (-20°C to 85°C). This part is actively produced by APEM Inc. with current inventory availability and carries comprehensive regulatory approvals (CSA, DEMKO, FEMCO, NEMKO, SEMKO, SEV, UL, VDE).

Substitute Selection (TRG22F2BBRLN): The TRG22F2BBRLN manufactured by ZF Electronics is suitable as a substitute when:

• Application current requirements do not exceed 16A AC
• Operating environment remains within -20°C to 65°C
• Electrical cycle life requirements do not exceed 6,000 cycles
• Panel cutout tolerance accommodates the 30.20mm dimension

Both parts maintain identical mechanical interfaces, termination standards, and visual/illumination characteristics, ensuring functional equivalence within their respective electrical ratings.

Frequently Asked Questions (FAQ)

Q: Can the TRG22F2BBRLN directly replace the RH110C2LBR in all applications?

A: Direct replacement is permissible only when the application current requirement does not exceed 16A AC and the operating temperature remains within -20°C to 65°C. The TRG22F2BBRLN is not suitable for applications requiring the full 20A capacity or extended high-temperature operation of the RH110C2LBR.

Q: Are the panel cutout dimensions compatible between these two switches?

A: The panel cutout dimensions are functionally compatible. The RH110C2LBR requires 30.00mm x 11.00mm; the TRG22F2BBRLN requires 30.20mm x 11.00mm. The 0.20mm difference in width is within typical panel fabrication tolerances for snap-in mounting applications.

Q: What is the difference in electrical life between these switches?

A: The RH110C2LBR is rated for 10,000 electrical cycles, while the TRG22F2BBRLN is rated for 6,000 electrical cycles. Applications with high switching frequency should account for this difference in component selection.

Q: Do both switches have the same regulatory certifications?

A: Both switches are ROHS3 compliant and REACH unaffected. The RH110C2LBR carries approvals from CSA, DEMKO, FEMCO, NEMKO, SEMKO, SEV, UL, and VDE. Regulatory approvals for the TRG22F2BBRLN are not specified in the available documentation.

Q: What is the maximum operating temperature for each switch?

A: The RH110C2LBR operates from -20°C to 85°C. The TRG22F2BBRLN operates from -20°C to 65°C. Applications requiring operation above 65°C must use the RH110C2LBR.

Q: Are the termination connectors identical?

A: Yes. Both switches use quick-connect 0.250" (6.3mm) termination, ensuring compatibility with existing wiring harnesses and connector systems.
