Key Parameters

Substitute Part Grouping Explanation

Substitution for the WR18AF/V is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Switch function (Mom-Off-Mom)
• Current rating (15A AC/DC)
• Voltage ratings (125V AC, 30V DC)
• Mounting type (Panel Mount, Snap-In)
• Actuator type and color (Concave, Black)
• Termination style (Quick Connect - 0.250")
• Panel cutout dimensions (Rectangular - 34.20mm x 17.20mm)
• Ingress protection rating (IP67)
• Operating temperature range (-25°C to 85°C)
• Mechanical and electrical life specifications

The substitute part WR18AF meets all these criteria and is classified as an active product, providing a direct functional and mechanical equivalent to the obsolete WR18AF/V.

Parameter Comparison

Engineering Selection Recommendations

The WR18AF serves as the direct equivalent to the obsolete WR18AF/V. Both parts are manufactured by NKK Switches within the WR series and maintain identical electrical and mechanical specifications. The WR18AF is currently in active production status, ensuring availability for new designs and replacement applications.

The WR18AF carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Both parts hold EN and UL approvals, confirming compliance with international safety standards. The transition from WR18AF/V to WR18AF involves no functional compromise and is suitable for direct substitution in applications requiring SPDT momentary-off-momentary rocker switches rated for 15A at 125V AC.

Frequently Asked Questions (FAQ)

Q: Can WR18AF directly replace WR18AF/V in existing applications?

A: Yes. The WR18AF is a direct functional and mechanical equivalent. All electrical ratings, switching characteristics, mounting dimensions, and termination styles are identical. The primary difference is product status: WR18AF/V is obsolete while WR18AF is active production.

Q: What are the critical parameters for substitution compatibility?

A: Substitution requires matching circuit configuration (SPDT), switch function (Mom-Off-Mom), current and voltage ratings (15A at 125V AC / 30V DC), mounting type (Panel Mount, Snap-In), actuator specifications (Concave, Black), termination style (Quick Connect - 0.250"), and panel cutout dimensions (34.20mm x 17.20mm).

Q: Are there packaging differences between WR18AF/V and WR18AF?

A: The WR18AF/V was supplied with specific packaging (indicated as "-" in available data), while WR18AF is supplied in bulk packaging. This distinction does not affect component functionality or mechanical compatibility.

Q: What compliance certifications apply to the substitute part?

A: The WR18AF holds ROHS3 compliance and REACH unaffected status. Both WR18AF/V and WR18AF carry EN and UL approvals, confirming compliance with international electrical safety standards.

Q: Are the mechanical and electrical life ratings identical?

A: Yes. Both parts specify 30,000 mechanical cycles and 10,000 electrical cycles, ensuring equivalent operational durability and reliability.
