R1966ABLKREDFG Equivalent & Substitute Parts

Part Overview

The R1966ABLKREDFG is an E-Switch rocker switch with SPST (Single Pole Single Throw) circuit configuration, rated for 15A AC at 125V. This panel mount, snap-in switch features a red concave actuator with on-off functionality and quick connect 0.187" termination. The product is active and maintains 740 units in current inventory stock.

Substitute parts become necessary when the primary part experiences extended lead times, inventory constraints, or when design requirements permit operation within expanded electrical or mechanical performance parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R1966ABLKREDFG is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST
• Switch function: On-Off
• Voltage rating: 125V AC
• Mounting type: Panel Mount, Snap-In
• Termination style: Quick Connect - 0.187" (4.7mm)
• Actuator color: Red
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Current rating: 15A or higher
• Panel cutout dimensions: Within tolerance of 19.40mm x 13.00mm ± acceptable mechanical fit
• Operating temperature range: Equal to or broader than -30°C to 65°C
• Mechanical and electrical life: Equal to or exceeding specified cycles

The substitute parts GRL-4011-1600 and GRS-4011-0040 (both CW Industries) meet all mandatory matching criteria and exceed allowable variation thresholds, qualifying them as direct substitutes.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain active product status and full ROHS3 compliance with REACH unaffected designation, meeting regulatory requirements equivalent to the primary part.

GRS-4011-0040 Selection Criteria: This substitute provides non-illuminated operation matching the R1966ABLKREDFG functional profile. Current rating elevation to 16A and extended mechanical/electrical life cycles provide enhanced performance margin. Panel cutout dimensions (19.20mm x 12.90mm) are mechanically compatible within standard tolerance ranges. Operating temperature expansion to -20°C to 105°C accommodates broader environmental applications.

GRL-4011-1600 Selection Criteria: This substitute incorporates integrated neon red illumination at 125VAC, introducing functional enhancement beyond the primary part specification. Identical electrical ratings, mounting configuration, and termination style ensure direct circuit compatibility. Mechanical and electrical life specifications exceed primary part performance. Panel cutout dimensions remain mechanically compatible. Operating temperature range expansion matches GRS-4011-0040 capability.

Selection between GRS-4011-0040 and GRL-4011-1600 depends on illumination requirement: GRS-4011-0040 for non-illuminated applications; GRL-4011-1600 for illuminated panel indication.

Frequently Asked Questions (FAQ)

Q: Can GRS-4011-0040 or GRL-4011-1600 directly replace R1966ABLKREDFG in existing designs?

A: Both parts share identical circuit configuration (SPST), voltage rating (125V AC), mounting type (panel mount, snap-in), and termination style (quick connect 0.187"). Panel cutout dimensions are mechanically compatible. Direct substitution is supported without circuit redesign.

Q: What is the difference between GRS-4011-0040 and GRL-4011-1600?

A: GRS-4011-0040 operates without illumination, maintaining functional equivalence to R1966ABLKREDFG. GRL-4011-1600 includes integrated neon red illumination powered at 125VAC, providing visual panel indication. Both share identical electrical ratings and mechanical specifications.

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

A: R1966ABLKREDFG specifies 19.40mm x 13.00mm; both CW Industries substitutes specify 19.20mm x 12.90mm. These dimensions are mechanically compatible within standard panel mounting tolerances. Verify panel cutout dimensions in your specific application to confirm fit.

Q: Do the substitute parts support the same current and voltage ratings?

A: R1966ABLKREDFG is rated 15A AC at 125V. Both substitutes are rated 16A AC at 125V, providing 1A additional current capacity. Voltage rating remains identical at 125V AC. Substitutes are suitable for applications requiring 15A or less.

Q: What compliance certifications apply to all three parts?

A: All three parts maintain ROHS3 compliance and REACH unaffected status. ECCN classification is EAR99 for all parts. Moisture sensitivity level is 1 (unlimited) across all variants.

Q: How do mechanical and electrical life cycles compare?

A: R1966ABLKREDFG specifies 30,000 mechanical cycles and 10,000 electrical cycles. Both substitutes specify 100,000 mechanical cycles and 25,000 electrical cycles, providing extended operational life margins.

Q: What is the operating temperature range for each part?

A: R1966ABLKREDFG operates from -30°C to 65°C. Both substitutes operate from -20°C to 105°C, providing expanded temperature capability. Verify application temperature requirements to confirm suitability.
