RA1066ASG Equivalent & Substitute Parts

Part Overview

The RA1066ASG 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 O/I marking and solder lug termination. The product is currently obsolete, making identification of compatible substitute parts essential for ongoing maintenance, repair, and design continuity in applications requiring equivalent switching functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RA1066ASG is determined by strict alignment of the following electrical and mechanical parameters:

Critical Substitution Criteria:

• Circuit configuration: SPST (maintained)
• Switch function: On-Off (maintained)
• Voltage rating: 125V AC (maintained)
• Mounting type: Panel Mount, Snap-In (maintained)
• Panel cutout dimensions: Rectangular 19.20mm x 13.00mm (maintained)
• Actuator type: Concave (Curved) (maintained)
• Actuator color: Black (maintained)
• Termination style: Solder Lug (maintained)

Allowable Variation:

• Current rating: The substitute part may have a higher current rating (16A) while maintaining all other electrical and mechanical specifications. A higher current rating does not compromise compatibility in applications designed for 10A operation.

The PRASA1-16L-BB0CW from TE Connectivity ALCOSWITCH Switches meets all critical substitution criteria and is classified as an equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The PRASA1-16L-BB0CW is a direct substitute for the obsolete RA1066ASG based on electrical and mechanical parameter alignment. Both parts maintain identical circuit configuration, voltage rating, mounting specifications, and physical panel cutout dimensions.

The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain continuity
• Higher current rating (16A vs. 10A) provides additional operational margin in existing 10A applications
• Extended mechanical life (100,000 cycles vs. 25,000 cycles) improves long-term reliability
• Compliance with UL and VDE standards is maintained; ENEC certification provides additional European market validation
• ROHS3 compliance is retained

Both parts carry identical RoHS and REACH compliance status. The substitute part includes dust proof ingress protection and specified operating temperature range (-20°C to 85°C), providing enhanced environmental performance.

Frequently Asked Questions (FAQ)

Q: Can the PRASA1-16L-BB0CW directly replace the RA1066ASG in existing applications?

A: Yes. Both parts share identical SPST circuit configuration, 125V AC voltage rating, panel mount snap-in mounting type, 19.20mm x 13.00mm panel cutout dimensions, concave black actuator, and solder lug termination. The higher 16A current rating of the substitute does not affect compatibility in applications designed for 10A operation.

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

A: The PRASA1-16L-BB0CW is rated for 16A AC, compared to the original 10A AC rating. This higher rating provides additional operational margin and does not create compatibility issues when used in 10A applications. The switch will function identically within the original design parameters.

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

A: The substitute part offers 100,000 mechanical cycles compared to 25,000 cycles on the original, indicating improved durability. Electrical life is rated at 6,000 cycles for the substitute versus 10,000 cycles for the original. Both ratings are suitable for typical on-off switching applications.

Q: What certifications apply to the substitute part?

A: The PRASA1-16L-BB0CW carries UL, VDE, and ENEC approvals. The original RA1066ASG carried CSA, DEMKO, FIMKO, NEMKO, SEMKO, UL, and VDE approvals. UL and VDE certifications are common to both parts, ensuring compliance in most regulatory environments.

Q: Is the packaging format compatible?

A: The substitute part is supplied in bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: Are both parts RoHS compliant?

A: Yes. Both the RA1066ASG and PRASA1-16L-BB0CW are ROHS3 compliant and REACH unaffected.
