CWSC11JDADS Equivalent & Substitute Parts

Part Overview

The CWSC11JDADS is a rocker switch manufactured by NKK Switches, classified as SPST (Single Pole Single Throw) with a 9A AC rating at 125V. This illuminated panel-mount switch features a concave actuator with amber LED illumination and quick-connect termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and design continuity in applications requiring compatible rocker switch solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CWSC11JDADS is determined by the following critical parameters:

• Circuit Configuration (SPST): The switch must maintain single-pole, single-throw functionality for direct replacement in on-off control applications.
• Current Rating: Substitute parts must support minimum 9A AC current to ensure adequate load-handling capacity.
• Voltage Rating: Substitute parts must support 125V AC minimum to maintain compatibility with the original application voltage.
• Mounting Type: Panel mount, snap-in configuration is required for mechanical fit within existing panel cutouts.
• Panel Cutout Dimensions: The rectangular 19.20mm x 12.90mm cutout dimension is a hard constraint for physical installation.
• Illumination: LED amber illumination at 2VDC is preferred but not mandatory for functional substitution.
• Termination Style: Quick-connect termination is preferred for ease of installation but alternative termination methods may be acceptable depending on application requirements.

Two substitute parts are identified based on these parameters, with varying degrees of compatibility:

JWS11RAAD: Maintains SPST circuit configuration, 125V AC voltage, and panel cutout dimensions. Current rating is reduced to 6A AC, representing a downgrade in electrical capacity. Termination includes both solder and quick-connect options. Product status is active.

CWSB21DADF: Shares panel cutout dimensions and 125V AC voltage rating but differs in circuit configuration (DPST instead of SPST), representing a functional change rather than a direct equivalent. Current rating remains at 9A AC. Product status is active.

Parameter Comparison

Engineering Selection Recommendations

JWS11RAAD is the preferred substitute for direct replacement applications. It maintains SPST circuit configuration and 125V AC voltage compatibility. The 6A AC current rating represents a reduction from the original 9A specification; this substitute is suitable only for applications where the actual load current does not exceed 6A AC. The JWS11RAAD offers expanded regulatory approvals (CSA, UL, VDE) compared to the original part's UL-only certification, and an extended operating temperature range (-25°C to 50°C). The product is currently active in production, ensuring availability for procurement.

CWSB21DADF is not a direct functional equivalent due to its DPST (Double Pole Single Throw) circuit configuration, which differs fundamentally from the original SPST design. This part is suitable only for applications requiring dual-pole switching capability. The CWSB21DADF maintains the 9A AC current rating and offers an extended operating temperature range (-20°C to 85°C). Neon illumination replaces the original LED illumination, with illumination voltage at 125 VAC rather than 2 VDC. The product is currently active in production.

Both substitute parts share identical panel cutout dimensions with the original part, ensuring mechanical compatibility with existing panel installations. All three parts are ROHS3 compliant and carry unlimited moisture sensitivity level (MSL 1) ratings.

Frequently Asked Questions (FAQ)

Q: Can JWS11RAAD be used as a direct replacement for CWSC11JDADS?

A: JWS11RAAD is mechanically and electrically compatible for applications where the load current does not exceed 6A AC. The original CWSC11JDADS is rated for 9A AC; if your application requires the full 9A capacity, JWS11RAAD is not suitable. Both parts maintain SPST circuit configuration, 125V AC voltage rating, and identical panel cutout dimensions.

Q: What is the difference between SPST and DPST circuit configurations?

A: SPST (Single Pole Single Throw) controls a single circuit with one on-off switch. DPST (Double Pole Single Throw) controls two independent circuits simultaneously with a single actuator. CWSB21DADF's DPST configuration is not functionally equivalent to the original SPST design unless your application specifically requires dual-circuit control.

Q: Are the panel cutout dimensions identical across all three parts?

A: Yes. All three parts—CWSC11JDADS, JWS11RAAD, and CWSB21DADF—share the same rectangular panel cutout dimensions of 19.20mm x 12.90mm, ensuring mechanical compatibility with existing panel installations.

Q: What is the difference between LED and Neon illumination?

A: The original CWSC11JDADS uses LED illumination requiring 2 VDC. CWSB21DADF uses Neon illumination requiring 125 VAC. These illumination types have different electrical requirements and cannot be directly interchanged without circuit modifications.

Q: Why is the CWSC11JDADS marked as obsolete?

A: The CWSC11JDADS is no longer in active production by NKK Switches. Both identified substitutes (JWS11RAAD and CWSB21DADF) are currently active products, ensuring long-term availability for new designs and replacement applications.

Q: Are all three parts RoHS compliant?

A: Yes. CWSC11JDADS, JWS11RAAD, and CWSB21DADF are all ROHS3 compliant, meeting environmental and hazardous substance restrictions for electronic components.

Q: What regulatory approvals do the substitute parts carry?

A: JWS11RAAD carries CSA, UL, and VDE approvals. CWSB21DADF carries cULus approval. The original CWSC11JDADS carries UL approval. Verify that the substitute part's regulatory certifications meet your application's compliance requirements.
