OP-XR3 Equivalent & Substitute Parts Reference

Part Overview

The OP-XR3 is a snap action SPDT (Single Pole Double Throw) switch manufactured by Honeywell Sensing and Productivity Solutions. This chassis mount switch is rated for 15A AC at 125V and 500mA DC at 125V, featuring a side rotary roller actuator with steel roller construction. The OP-XR3 is classified as obsolete, making identification of equivalent substitute parts essential for system maintenance, repair, and component sourcing. The availability of active alternative models ensures continued access to functionally compatible switching solutions.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OP-XR3 is based on strict electrical and mechanical parameter matching within the Honeywell snap action switch product line. The substitute part EX-XR3 maintains functional equivalence through identical specifications in the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: SPDT
• Switch function: On-On
• Current rating: 15A (AC), 500mA (DC)
• Voltage rating: 125V (AC and DC)

Mechanical Equivalence Criteria:

• Actuator type: Side Rotary, Roller
• Mounting type: Chassis Mount
• Termination style: Wire Leads
• Operating force: 340gf
• Pretravel: 0.219" (5.6mm)
• Overtravel: 90°

Compliance Equivalence:

• RoHS Compliant status
• MSL rating: 1 (Unlimited)
• ECCN classification: EAR99
• HTSUS code: 8536.50.9055

The EX-XR3 represents an active product alternative within the same manufacturer's portfolio, differing primarily in series designation (EX versus OP) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The EX-XR3 serves as a direct functional equivalent to the obsolete OP-XR3 based on complete electrical and mechanical parameter alignment. Selection of the EX-XR3 is supported by the following engineering factors:

Product Status Consideration: The OP-XR3 is classified as obsolete, limiting long-term availability and supply chain reliability. The EX-XR3 maintains active product status, ensuring continued manufacturing support and component availability.

Compliance Alignment: Both parts maintain identical RoHS compliance status and MSL ratings, confirming suitability for equivalent environmental and regulatory applications. ECCN and HTSUS classifications are identical, indicating no change in export control or tariff treatment.

Electrical and Mechanical Compatibility: All specified electrical parameters (current and voltage ratings, circuit configuration) and mechanical parameters (actuator type, mounting configuration, operating force, travel specifications) are identical between the two parts. This ensures direct functional substitution without circuit redesign or mechanical modification.

Series Differentiation: The transition from OP series to EX series reflects manufacturer product line evolution. The EX-XR3 incorporates explosion-proof features as indicated in its detailed description, providing enhanced capability while maintaining all baseline specifications of the OP-XR3.

Frequently Asked Questions (FAQ)

Q: Can the EX-XR3 directly replace the OP-XR3 in existing applications?

A: Yes. The EX-XR3 maintains identical electrical ratings (15A AC at 125V, 500mA DC at 125V), circuit configuration (SPDT), and mechanical specifications (side rotary roller actuator, chassis mount, wire leads). All operating parameters including force, travel, and overtravel are identical. Direct substitution is supported by complete parameter equivalence.

Q: What is the primary difference between the OP-XR3 and EX-XR3?

A: The primary differences are product status and series designation. The OP-XR3 is obsolete, while the EX-XR3 is active. The EX-XR3 series incorporates explosion-proof design features. All electrical and mechanical specifications remain identical.

Q: Are there packaging differences between these parts?

A: The OP-XR3 packaging is not specified in available documentation. The EX-XR3 is supplied in bulk packaging. Packaging differences do not affect electrical or mechanical compatibility; they relate only to order quantity and handling considerations.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the OP-XR3 and EX-XR3 are RoHS Compliant with MSL rating of 1 (Unlimited). Both carry identical ECCN (EAR99) and HTSUS (8536.50.9055) classifications, confirming equivalent regulatory and trade treatment.

Q: What parameters must remain identical for substitution to be valid?

A: Substitution validity is determined by matching: circuit configuration (SPDT), switch function (On-On), current ratings (15A AC / 500mA DC), voltage ratings (125V AC/DC), actuator type (side rotary roller), mounting type (chassis mount), termination style (wire leads), operating force (340gf), pretravel (0.219" / 5.6mm), and overtravel (90°). All these parameters are identical between the OP-XR3 and EX-XR3.

Q: Is the EX-XR3 suitable for applications requiring explosion-proof certification?

A: The EX-XR3 is identified as incorporating explosion-proof features. Applications requiring explosion-proof certification should reference the complete technical documentation and certification records for the EX-XR3 to confirm suitability for specific hazardous area classifications.
