Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRASD1-16F-BB0EW is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT
• Switch function: On-On
• Voltage rating: 125V AC
• Mounting type: Panel Mount, Snap-In
• Actuator type: Concave (Curved)
• Actuator color: Black
• Termination style: Quick Connect - 0.187" (4.7mm)
• Panel cutout dimensions: Rectangular format within tolerance

Allowable Variation Parameters:

• Current rating: Substitute parts may have lower current ratings (15A, 10A) provided the application does not exceed the substitute's rating
• Operating temperature range: Substitute parts may have narrower ranges
• Mechanical and electrical life cycles: Substitute parts may have different cycle ratings
• Panel cutout dimensions: Minor dimensional variations within standard tolerance

The identified substitute parts (R1966CBLKBLKFF and SRB23A2BBBNN) maintain all mandatory compatibility parameters while varying in current rating and operational characteristics.

Parameter Comparison

Engineering Selection Recommendations

PRASD1-16F-BB0EW (Primary Selection)

The PRASD1-16F-BB0EW is the primary component specification. This part is actively produced by TE Connectivity ALCOSWITCH Switches and carries full RoHS3 compliance. It provides the highest current rating (16A AC) and the widest operating temperature range (-20°C to 85°C) among the three options. The mechanical life rating of 100,000 cycles supports extended service life applications. This part is suitable for all applications within its specified electrical and mechanical parameters.

R1966CBLKBLKFF (E-Switch Substitute)

The R1966CBLKBLKFF is an active substitute from E-Switch. This part maintains full electrical and mechanical compatibility with the main part, including SPDT circuit configuration, 125V AC rating, and identical termination style. The current rating is reduced to 15A AC, making this substitute suitable for applications not exceeding 15A. The operating temperature range is narrower (-30°C to 65°C), with lower mechanical life (30,000 cycles) but higher electrical life (10,000 cycles). Panel cutout dimensions are 19.40mm x 13.00mm, representing a 0.20mm increase in width. This part is RoHS3 compliant and actively produced.

SRB23A2BBBNN (ZF Electronics Substitute)

The SRB23A2BBBNN is an active substitute from ZF Electronics. This part maintains full electrical and mechanical compatibility with the main part, including SPDT circuit configuration, 125V AC rating, and identical termination style. The current rating is reduced to 10A AC, making this substitute suitable for applications not exceeding 10A. The operating temperature range is -20°C to 65°C, with mechanical life matching the main part (100,000 cycles) and electrical life at 6,000 cycles. Panel cutout dimensions are 19.10mm x 12.90mm, representing a 0.10mm decrease in width and 0.10mm decrease in height. This part is RoHS3 compliant and actively produced.

Frequently Asked Questions (FAQ)

Q: Can R1966CBLKBLKFF replace PRASD1-16F-BB0EW in all applications?

A: R1966CBLKBLKFF is compatible with PRASD1-16F-BB0EW for applications requiring 15A AC or less. The reduced current rating is the limiting factor. All other electrical and mechanical parameters are compatible. Panel cutout dimensions differ by 0.20mm in width.

Q: What is the primary limitation of SRB23A2BBBNN as a substitute?

A: The primary limitation is the reduced current rating of 10A AC. SRB23A2BBBNN is suitable only for applications not exceeding 10A. The operating temperature range is also narrower (maximum 65°C versus 85°C for the main part).

Q: Are all three parts panel mount, snap-in compatible?

A: Yes. All three parts feature panel mount, snap-in installation with Quick Connect 0.187" (4.7mm) termination. Panel cutout dimensions are within 0.20mm tolerance across all three parts.

Q: Do all substitute parts meet RoHS3 compliance?

A: Yes. Both R1966CBLKBLKFF and SRB23A2BBBNN are RoHS3 compliant, matching the compliance status of PRASD1-16F-BB0EW.

Q: Which substitute part has the longest mechanical life?

A: Both PRASD1-16F-BB0EW and SRB23A2BBBNN are rated for 100,000 mechanical cycles. R1966CBLKBLKFF is rated for 30,000 cycles.

Q: Can these parts be used interchangeably in existing designs?

A: Interchangeability depends on the application's current requirement. If the application requires 16A, only PRASD1-16F-BB0EW is suitable. If the application requires 15A or less, R1966CBLKBLKFF is compatible. If the application requires 10A or less, SRB23A2BBBNN is compatible. Panel cutout dimensions must be verified for each application.

Q: What is the difference in operating temperature ranges?

A: PRASD1-16F-BB0EW operates from -20°C to 85°C. R1966CBLKBLKFF operates from -30°C to 65°C (lower maximum). SRB23A2BBBNN operates from -20°C to 65°C (lower maximum). Applications requiring operation above 65°C require the main part.

Q: Are all parts actively produced?

A: Yes. PRASD1-16F-BB0EW, R1966CBLKBLKFF, and SRB23A2BBBNN are all listed as active products with current inventory availability.
