R1966AWHTWHTFF Equivalent & Substitute Parts

Part Overview

The R1966AWHTWHTFF is an E-Switch rocker switch with SPST (Single Pole Single Throw) configuration, rated for 15A at 125V AC. This panel-mount, snap-in switch features a white concave actuator with O/- marking and quick connect 0.187" termination. The product is active and ROHS3 compliant with unlimited moisture sensitivity rating. Alternative models may be required due to inventory constraints, application-specific requirements, or regional availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the R1966AWHTWHTFF is determined by the following critical parameters:

• Circuit configuration must remain SPST
• Voltage rating must be 125V AC minimum
• Mounting type must be panel mount, snap-in
• Termination style must be quick connect 0.187" (4.7mm)
• Panel cutout dimensions must be compatible within mechanical tolerance
• RoHS3 compliance required

The substitute part SRB22A2BBBNN from ZF Electronics meets these core requirements. However, the current rating differs: the substitute is rated for 10A AC versus the original 15A AC specification. This represents a reduction in maximum current capacity and must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the R1966AWHTWHTFF and SRB22A2BBBNN are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts must be based on application current requirements:

• Use R1966AWHTWHTFF for applications requiring 15A AC switching capacity
• Use SRB22A2BBBNN only for applications with maximum current draw of 10A AC or less

The SRB22A2BBBNN offers superior mechanical life (100,000 cycles versus 30,000 cycles) but reduced electrical life (6,000 cycles versus 10,000 cycles). Panel cutout dimensions are nominally compatible with minor dimensional variance (19.10mm x 12.90mm versus 19.40mm x 13.00mm). Operating temperature range is narrower on the substitute (-20°C minimum versus -30°C minimum).

Frequently Asked Questions (FAQ)

Q: Can SRB22A2BBBNN replace R1966AWHTWHTFF in all applications?

A: No. The substitute part is rated for 10A AC maximum, while the original is rated for 15A AC. Substitution is valid only for applications with current requirements of 10A AC or less.

Q: Are the panel cutout dimensions compatible?

A: The dimensions are nominally compatible. R1966AWHTWHTFF requires 19.40mm x 13.00mm; SRB22A2BBBNN requires 19.10mm x 12.90mm. Mechanical tolerance must be verified for the specific panel application.

Q: What is the difference in operating temperature range?

A: R1966AWHTWHTFF operates from -30°C to 65°C. SRB22A2BBBNN operates from -20°C to 65°C. For applications below -20°C, only the original part is suitable.

Q: Do both parts use the same termination?

A: Yes. Both parts use quick connect 0.187" (4.7mm) termination, ensuring electrical compatibility.

Q: Which part has longer mechanical life?

A: SRB22A2BBBNN has 100,000 mechanical cycles versus 30,000 cycles for R1966AWHTWHTFF. However, electrical life is lower on the substitute (6,000 cycles versus 10,000 cycles).

Q: Are both parts RoHS compliant?

A: Yes. Both R1966AWHTWHTFF and SRB22A2BBBNN are ROHS3 compliant and REACH unaffected.
