RA1066ASX Equivalent & Substitute Parts

Part Overview

The RA1066ASX is a rocker switch manufactured by E-Switch, classified as SPST (Single Pole Single Throw) with a 10A AC rating at 125V. This panel mount, snap-in switch features a concave black actuator with solder lug termination and is designed for on-off switching applications. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the RA1066ASX is determined by the following critical parameters:

• Circuit Configuration: Must be SPST (Single Pole Single Throw)
• Switch Function: Must be On-Off
• Voltage Rating (AC): Must be rated for 125V AC minimum
• Current Rating (AC): Must be rated for 10A AC minimum
• Mounting Type: Must be Panel Mount, Snap-In
• Panel Cutout Dimensions: Must accommodate Rectangular 19.20mm x 13.00mm opening
• Actuator Type: Concave (Curved) preferred for form factor compatibility
• Termination Style: Solder Lug required for circuit board integration
• Actuator Color: Black for visual consistency

The substitute part PRASA1-16L-BB000 meets all critical substitution criteria. It maintains identical circuit configuration, mounting type, panel cutout dimensions, actuator type, color, and termination style. The substitute provides enhanced current rating (16A vs. 10A) and voltage compatibility at 125V AC, making it a direct functional replacement suitable for the RA1066ASX application.

Parameter Comparison

Engineering Selection Recommendations

The PRASA1-16L-BB000 is the manufacturer-recommended substitute for the obsolete RA1066ASX. Both parts carry UL and VDE certifications, meeting international safety standards for AC switching applications. The substitute maintains full mechanical and electrical compatibility through identical mounting geometry, actuator design, and termination method.

The PRASA1-16L-BB000 is currently in active production status with 1146 units in stock, ensuring availability for immediate deployment. The substitute's higher current rating (16A vs. 10A) and enhanced mechanical life (100,000 vs. 25,000 cycles) provide improved performance margins for the same 125V AC application. The addition of dust proof ingress protection and specified operating temperature range (-20°C ~ 85°C) extends environmental suitability.

Selection of the PRASA1-16L-BB000 is appropriate for all applications previously served by the RA1066ASX where 125V AC, 10A SPST on-off switching with panel mount snap-in installation is required.

Frequently Asked Questions (FAQ)

Q: Can the PRASA1-16L-BB000 directly replace the RA1066ASX without circuit modification?

A: Yes. The substitute maintains identical panel cutout dimensions (19.20mm x 13.00mm), solder lug termination, and SPST on-off switching function. No circuit board modifications are required for physical or electrical integration.

Q: What is the significance of the higher current rating on the substitute part?

A: The PRASA1-16L-BB000 is rated for 16A AC versus the RA1066ASX's 10A AC rating. This higher rating provides additional safety margin in applications operating at or near the original 10A specification and does not negatively impact compatibility.

Q: Are there differences in mechanical or electrical life between these parts?

A: The RA1066ASX specifies 25,000 mechanical cycles and 10,000 electrical cycles. The PRASA1-16L-BB000 specifies 100,000 mechanical cycles and 6,000 electrical cycles. The substitute offers significantly extended mechanical durability, though electrical cycle life is lower. Application requirements should determine which specification is critical.

Q: What certifications apply to the substitute part?

A: The PRASA1-16L-BB000 carries ENEC, UL, and VDE certifications. The original RA1066ASX carried CSA, DEMKO, FIMKO, NEMKO, SEMKO, UL, and VDE certifications. Both parts meet UL and VDE standards required for 125V AC switching applications in most markets.

Q: Is the substitute part available in the same packaging format?

A: The PRASA1-16L-BB000 is supplied in bulk packaging. Packaging format differences do not affect functional compatibility or installation characteristics.

Q: Can the substitute be used in applications requiring the original RoHS3 compliance status?

A: The PRASA1-16L-BB000 RoHS status is listed as not applicable. Applications with specific RoHS compliance requirements should be evaluated against the substitute's material composition and regulatory status in the target market.
