Omron A165L-ARM-5-2 Pushbutton Switch - Equivalent & Substitute Parts

Part Overview

The Omron A165L-ARM-5-2 is a DPDT illuminated pushbutton switch rated for 5A at 125V AC, designed for panel-mount front installation. This component features an incandescent red illumination system and is classified as obsolete. Due to its obsolete status, identifying functionally equivalent active alternatives is necessary for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

The A165L-ARM-5D-2 qualifies as a direct substitute based on the following critical parameters:

Electrical Compatibility:

• Identical circuit configuration (DPDT)
• Identical current rating (5A AC)
• Identical voltage rating (125V AC)
• Identical switch function (On-Mom)

Mechanical Compatibility:

• Identical mounting type (Panel Mount, Front)
• Identical panel cutout dimensions (Circular - 16.00mm Dia)
• Identical actuator type (Square, Button)
• Identical termination style (Solder, Quick Connect - 0.110")

Environmental Compatibility:

• Identical ingress protection rating (IP66)
• Identical operating temperature range (-10°C to 55°C)
• Identical mechanical life rating (2,000,000 Cycles)
• Identical electrical life rating (100,000 Cycles)

Key Difference: The primary distinction between the main part and substitute is the illumination technology: the A165L-ARM-5-2 uses incandescent illumination at 5 VAC/DC, while the A165L-ARM-5D-2 uses LED illumination at 5 VDC. Both maintain identical color output (red) and are compatible with the same panel cutout and termination interfaces.

Parameter Comparison

Engineering Selection Recommendations

The A165L-ARM-5D-2 is the appropriate substitute for the obsolete A165L-ARM-5-2 based on the following factors:

Product Status: The A165L-ARM-5D-2 maintains active product status, ensuring continued availability and manufacturer support, whereas the A165L-ARM-5-2 is classified as obsolete.

Regulatory Compliance: The A165L-ARM-5D-2 meets ROHS3 compliance requirements, representing current regulatory standards. The main part meets RoHS compliance but does not specify ROHS3 status.

Functional Equivalence: All critical electrical, mechanical, and environmental parameters are identical between the two parts. The substitution maintains full compatibility with existing panel cutouts, termination interfaces, and circuit requirements.

Illumination Technology Consideration: The transition from incandescent to LED illumination in the substitute part represents a technology upgrade. LED illumination operates at 5 VDC (versus the original 5 VAC/DC), which may require circuit verification if the illumination supply is AC-only. LED technology provides extended operational life and reduced power consumption compared to incandescent systems.

Frequently Asked Questions (FAQ)

Q: Can the A165L-ARM-5D-2 be used as a direct replacement for the A165L-ARM-5-2 in existing installations?

A: Yes, the A165L-ARM-5D-2 is mechanically and electrically compatible. The panel cutout diameter, termination style, and all electrical ratings are identical. However, the illumination voltage requirement differs: the substitute requires 5 VDC, while the original accepts 5 VAC/DC. Verify that your illumination supply can provide 5 VDC before installation.

Q: What is the primary difference between these two parts?

A: The illumination technology differs. The A165L-ARM-5-2 uses incandescent illumination compatible with 5 VAC/DC supplies. The A165L-ARM-5D-2 uses LED illumination requiring 5 VDC. Both provide red illumination and are otherwise functionally equivalent.

Q: Are the panel mounting dimensions identical?

A: Yes. Both parts feature a circular 16.00mm diameter panel cutout and identical front-mount installation requirements. No mechanical modifications to the panel are necessary when substituting.

Q: Do both parts have the same electrical ratings?

A: Yes. Both are rated for 5A AC at 125V AC with DPDT circuit configuration and On-Mom switch function. Electrical performance in the circuit is equivalent.

Q: What is the significance of the product status difference?

A: The A165L-ARM-5-2 is obsolete, meaning Omron no longer manufactures or supports this part. The A165L-ARM-5D-2 is active, ensuring ongoing availability and manufacturer technical support. For new designs or long-term system maintenance, the active substitute is the appropriate choice.

Q: Are the termination styles compatible?

A: Yes. Both parts use identical termination: Solder and Quick Connect - 0.110" (2.8mm). Existing wiring and connector interfaces are compatible without modification.

Q: What are the environmental operating conditions for both parts?

A: Both parts operate identically across -10°C to 55°C temperature range with IP66 ingress protection (dust tight, oil and water resistant). Environmental specifications are equivalent.
