Honeywell EX-AR230 Snap Action Switch: Equivalent & Substitute Parts

Part Overview

The Honeywell EX-AR230 is a snap action switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 15A AC at 125V and 500mA DC at 125V. This component features a side rotary actuator without lever, chassis mount configuration, and screw terminal termination. The EX-AR230 is classified as obsolete, making identification of active equivalent parts essential for ongoing system maintenance and new design implementations.

The EX-AR230 incorporates explosion-proof design features and operates across a temperature range of -40°C to 71°C. Its on-momentary switch function and specified mechanical characteristics (9.001–23gfm operating force, 0.219" pretravel, 90° overtravel) define its functional performance envelope.

Substitute Part Grouping Explanation

Substitution of the EX-AR230 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom
• Current rating: 15A AC / 500mA DC
• Voltage rating: 125V AC / 125V DC

Mechanical Equivalence Criteria:

• Actuator type: Side Rotary - No Lever
• Mounting type: Chassis Mount
• Termination style: Screw Terminal
• Operating force range: 9.001–23gfm
• Release force: 4.500gfm
• Pretravel: 0.219" (5.6mm)
• Differential travel: 0.007" (0.18mm)
• Overtravel: 90°

Environmental & Compliance Criteria:

• Operating temperature range: -40°C to 71°C
• Explosion-proof design
• RoHS compliance
• MSL rating: 1 (Unlimited)

The EX-AR20 qualifies as a direct substitute based on identical electrical ratings, mechanical specifications, actuator configuration, mounting method, and termination style. The primary distinction is product status: EX-AR20 is active, whereas EX-AR230 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The EX-AR20 is the direct functional and mechanical equivalent of the obsolete EX-AR230. Both components share identical electrical specifications, mechanical characteristics, actuator design, mounting configuration, and termination method. All critical parameters that determine switch performance and circuit compatibility are equivalent.

The EX-AR20 is classified as an active product, ensuring ongoing availability and manufacturer support. Both parts maintain RoHS compliance and identical MSL ratings, confirming equivalent environmental and regulatory standing.

The EX-AR20 is supplied in bulk packaging, whereas the EX-AR230 packaging specification is not provided. Packaging format does not affect electrical or mechanical compatibility; it reflects only distribution and inventory management differences.

For applications currently using the EX-AR230, direct substitution with the EX-AR20 is supported by complete parameter equivalence across all electrical, mechanical, and environmental criteria.

Frequently Asked Questions (FAQ)
