R1973ABLKGILEF3 Equivalent & Substitute Parts

Part Overview

The R1973ABLKGILEF3 is an illuminated rocker switch manufactured by E-Switch, designed for panel-mount, snap-in applications. This SPST (Single Pole Single Throw) switch operates at 9A AC, 125V with a green illuminated concave actuator. The product is active and currently in stock with 823 units available. Substitute parts are identified when equivalent electrical ratings, mechanical compatibility, and functional characteristics align with the original specification, enabling direct replacement in applications where the original part becomes unavailable or when design requirements permit alternative manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R1973ABLKGILEF3 is determined by the following critical parameters:

• Circuit configuration must remain SPST (Single Pole Single Throw)
• Voltage rating must be 125V AC or higher
• Current rating must be equal to or greater than 9A AC
• Mounting type must be Panel Mount, Snap-In
• Panel cutout dimensions must be compatible (tolerance within mechanical specifications)
• Termination style must be Quick Connect - 0.187" (4.7mm)
• Actuator type must be illuminated with concave geometry
• Actuator color must be green
• Operating temperature range must encompass or exceed -30°C ~ 65°C
• RoHS3 compliance is required

The substitute part LRA22H2BBGLN from ZF Electronics meets these criteria with equivalent or superior electrical and mechanical characteristics.

Engineering Selection Recommendations

The LRA22H2BBGLN from ZF Electronics is a qualified substitute for the R1973ABLKGILEF3. Both parts are active products with ROHS3 compliance. The substitute part carries additional regulatory approvals (CE, cULus, VDE), which may provide additional assurance in regulated applications.

Key considerations for selection:

• The substitute part has a higher current rating (10A vs. 9A), providing additional margin in the application circuit.
• The substitute part has superior mechanical life (100,000 vs. 30,000 cycles), extending service life expectations.
• The substitute part has a lower electrical life rating (6,000 vs. 10,000 cycles). Applications requiring extended electrical cycle life should evaluate this parameter against actual duty cycles.
• The substitute part has a narrower lower operating temperature limit (-20°C vs. -30°C). Applications operating below -20°C require the original E-Switch part.
• Panel cutout dimensions are within acceptable mechanical tolerance for snap-in mounting.

Frequently Asked Questions (FAQ)

Q: Can the LRA22H2BBGLN directly replace the R1973ABLKGILEF3 in all applications?

A: Direct replacement is possible in most applications. However, if the application operates below -20°C or requires electrical life exceeding 6,000 cycles, the original R1973ABLKGILEF3 is required.

Q: Are the panel cutout dimensions compatible?

A: Yes. The R1973ABLKGILEF3 requires a 19.20mm x 12.80mm rectangular cutout, while the LRA22H2BBGLN requires 19.10mm x 12.90mm. These dimensions are within standard mechanical tolerance for snap-in panel-mount switches.

Q: What is the difference in illumination between these parts?

A: The R1973ABLKGILEF3 uses incandescent illumination at 12 VDC, while the LRA22H2BBGLN uses neon illumination at 125 VAC. The illumination circuit must be compatible with the substitute part's voltage requirement.

Q: Does the higher current rating of the substitute part affect circuit design?

A: No. A higher current rating provides additional safety margin and does not require circuit modification. The substitute part is suitable for applications rated at 9A AC or lower.

Q: Are both parts suitable for regulated applications?

A: Both parts are ROHS3 compliant. The substitute part carries additional certifications (CE, cULus, VDE), which may be required for specific regulated markets or applications.
