• Voltage rating: 125V AC
• Operating temperature range: -10°C to 55°C
• Mechanical life: 2,000,000 cycles
• Electrical life: 100,000 cycles

Mechanical Parameters (Identical):

• Mounting type: Panel Mount, Front
• Panel cutout dimensions: Circular 16.00mm diameter
• Actuator type: Square button
• Actuator color: Red
• Termination style: Solder, Quick Connect 0.110" (2.8mm)
• Ingress protection: IP66

Illumination Variation:

• Main part: Incandescent illumination, 12 VAC/DC
• Substitute part: LED illumination, 12 VDC

The substitute part maintains all electrical and mechanical specifications while incorporating LED illumination technology in place of incandescent. The substitute is currently in active production status, ensuring availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The A165L-ARM-12D-1 is the appropriate substitute for the obsolete A165L-ARM-12-1. Both parts maintain identical electrical and mechanical specifications, ensuring direct functional compatibility in existing applications. The substitute part is currently in active production status, providing assured supply chain availability compared to the obsolete main part.

Both parts are RoHS compliant and carry identical regulatory classifications (ECCN: EAR99, HTSUS: 8536.50.9031), supporting equivalent use in regulated applications.

The primary difference between the parts is the illumination technology: the substitute employs LED illumination at 12 VDC, whereas the original uses incandescent illumination at 12 VAC/DC. This change does not affect electrical or mechanical performance and represents a technology upgrade with improved reliability and reduced power consumption.

Frequently Asked Questions (FAQ)

Q: Can the A165L-ARM-12D-1 be used as a direct replacement for the A165L-ARM-12-1?

A: Yes. Both parts share identical circuit configuration (SPDT), current rating (5A AC), voltage rating (125V AC), mounting specifications, panel cutout dimensions, and ingress protection (IP66). All electrical and mechanical parameters are equivalent.

Q: What is the difference between the illumination specifications?

A: The original part uses incandescent illumination operating at 12 VAC/DC. The substitute uses LED illumination operating at 12 VDC. Both provide red illumination and operate at the same nominal voltage level. LED technology offers improved reliability and lower power consumption.

Q: Are there any compatibility concerns with the illumination voltage change?

A: The substitute part operates on 12 VDC, whereas the original accepts 12 VAC/DC. If the application circuit supplies 12 VAC only, the substitute illumination will not function. Verify that the illumination supply in your application provides 12 VDC or can be modified to do so.

Q: What is the packaging difference between these parts?

A: The original part (A165L-ARM-12-1) is supplied in standard packaging. The substitute part (A165L-ARM-12D-1) is supplied in bulk packaging. Both parts are identical in form, fit, and function.

Q: Are both parts RoHS compliant?

A: Yes. Both the A165L-ARM-12-1 and A165L-ARM-12D-1 are RoHS compliant and carry identical regulatory classifications.

Q: Why is the original part listed as obsolete?

A: The A165L-ARM-12-1 has been discontinued by the manufacturer. The A165L-ARM-12D-1 represents the current production equivalent, incorporating LED illumination technology while maintaining all electrical and mechanical specifications.
