PRASA1-16L-BB000 Equivalent & Substitute Parts

Part Overview

The PRASA1-16L-BB000 is a rocker switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a single-pole single-throw (SPST) on-off switch rated for 16A AC at 125V. The switch features panel mount snap-in installation with a concave black actuator and solder lug termination. The product is currently active in production with 1,146 pieces in stock.

Substitute parts are necessary when the original PRASA1-16L-BB000 becomes unavailable, when alternative electrical ratings are required for specific applications, or when design modifications necessitate different actuator markings or illumination options while maintaining compatible mechanical and electrical characteristics.

Substitute Part Grouping Explanation

Substitution of the PRASA1-16L-BB000 is determined by the following critical parameters:

Primary Compatibility Criteria:

Circuit configuration (SPST)
Switch function (On-Off)
Mounting type (Panel Mount, Snap-In)
Termination style (Solder Lug)
Panel cutout dimensions (Rectangular - 19.20mm x 13.00mm or compatible)
Actuator type (Concave/Curved)

Secondary Compatibility Criteria:

Current rating (16A AC or higher)
Voltage rating (125V AC or higher)
Operating temperature range (must encompass -20°C to 85°C or be compatible with application requirements)
Actuator color and marking (application-dependent)
Illumination requirements (if specified)

Substitute parts are grouped into two categories:

Category 1: Direct Electrical Equivalents – Parts with identical or superior electrical ratings (16A/125V or higher), matching mechanical form factor, and compatible panel cutout dimensions. These parts include E-Switch R1966 series variants with 15A/125V ratings and compatible panel cutout dimensions of 19.40mm x 13.00mm.

Category 2: Reduced Rating Alternatives – Parts with lower electrical ratings (6A/250V) that maintain SPST configuration and panel mount snap-in installation but are suitable only for applications with reduced current requirements. The APEM FMC12A2200000 falls into this category with obsolete product status.

Engineering Selection Recommendations

Primary Substitutes (E-Switch R1966 Series):

The E-Switch R1966 series variants (R1966ABLKBLKES, R1966ABLKBLKFS, R1966ABLKBLKGS, R1966ABLKBLKIS, R1966ABLKBLKESGRN, R1966ABLKBLKESRED, R1966ABLKBLKESYEL) are active products suitable for direct substitution in most applications. These parts maintain SPST configuration, panel mount snap-in installation, solder lug termination, and compatible panel cutout dimensions. The 15A AC rating at 125V is marginally lower than the PRASA1-16L-BB000 but remains within acceptable tolerance for most 16A-rated circuit applications. All R1966 variants are ROHS3 compliant and REACH unaffected.

Selection among R1966 variants depends on actuator marking and illumination requirements:

R1966ABLKBLKES: No marking, no illumination – closest functional equivalent
R1966ABLKBLKFS: "O" marking for power indication
R1966ABLKBLKGS: "O I" marking for on-off indication
R1966ABLKBLKIS: "ON OFF" vertical marking for explicit on-off labeling
R1966ABLKBLKESGRN, R1966ABLKBLKESRED, R1966ABLKBLKESYEL: LED-illuminated variants with green, red, or yellow indicators at 2.0-2.2 VDC

Operating temperature range for R1966 variants (-30°C to 65°C) is narrower than the PRASA1-16L-BB000 (-20°C to 85°C). Applications requiring operation above 65°C or below -30°C require the original PRASA1-16L-BB000.

Secondary Substitute (APEM FMC12A2200000):

The APEM FMC12A2200000 is an obsolete product with reduced electrical rating (6A AC at 250V). This part is suitable only for applications with current requirements not exceeding 6A. The obsolete product status makes this option unsuitable for new designs or long-term supply assurance. Use only when application current requirements are confirmed below 6A and existing inventory is available.

Compliance Considerations:

The PRASA1-16L-BB000 carries ENEC, UL, and VDE approvals. E-Switch R1966 variants do not specify approval agencies in the provided data. Applications requiring specific regulatory certifications (UL, VDE, ENEC) must confirm R1966 variant compliance with applicable standards before substitution.

Frequently Asked Questions (FAQ)

Q: Can R1966ABLKBLKES replace PRASA1-16L-BB000 in a 16A circuit?

A: The R1966ABLKBLKES is rated for 15A AC at 125V, which is 1A lower than the PRASA1-16L-BB000. For circuits operating continuously at or above 16A, the original part is required. For circuits operating below 15A, the R1966ABLKBLKES is electrically compatible. Circuit design margins and load characteristics determine suitability.

Q: What is the difference between R1966ABLKBLKIS and R1966ABLKBLKFS?

A: Both parts are identical except for actuator marking. R1966ABLKBLKIS features "ON OFF" vertical marking for explicit on-off indication. R1966ABLKBLKFS features "O" marking for power indication. Selection depends on user interface requirements and labeling standards for the application.

Q: Are the panel cutout dimensions compatible between PRASA1-16L-BB000 and R1966 variants?

A: The PRASA1-16L-BB000 requires a rectangular cutout of 19.20mm x 13.00mm. R1966 variants require 19.40mm x 13.00mm. The 0.20mm difference in width is within typical panel tolerance for snap-in switches but should be verified during mechanical design. Existing panel cutouts for PRASA1-16L-BB000 may require minor enlargement for R1966 installation.

Q: Can illuminated R1966 variants (with LED) replace the non-illuminated PRASA1-16L-BB000?

A: Illuminated variants (R1966ABLKBLKESGRN, R1966ABLKBLKESRED, R1966ABLKBLKESYEL) are mechanically and electrically compatible but require additional LED power supply connections. The illumination voltage ranges from 2.0 to 2.2 VDC. Use illuminated variants only when LED indication is required and power supply for illumination is available.

Q: What is the operating temperature limitation when substituting with R1966 variants?

A: R1966 variants operate from -30°C to 65°C, while PRASA1-16L-BB000 operates from -20°C to 85°C. Applications requiring operation above 65°C must use the original PRASA1-16L-BB000. Applications operating between -30°C and 65°C are compatible with R1966 variants.

Q: Is FMC12A2200000 suitable for general replacement of PRASA1-16L-BB000?

A: No. The FMC12A2200000 is rated for only 6A AC, compared to 16A AC for PRASA1-16L-BB000. Additionally, FMC12A2200000 is obsolete. Use this part only when application current requirements are confirmed below 6A and existing inventory is available for immediate use.

Q: Do all substitute parts have the same solder lug termination?

A: Yes. All substitute parts listed use solder lug termination, matching the PRASA1-16L-BB000. No termination style conversion is required.

Q: What regulatory approvals do E-Switch R1966 variants carry?

A: The provided data does not specify regulatory approvals for R1966 variants. Applications requiring UL, VDE, or ENEC certification must contact E-Switch directly to confirm compliance before substitution in regulated applications.
