PBES16L2FR Equivalent & Substitute Parts

Part Overview

The PBES16L2FR is a panel-mounted illuminated pushbutton switch manufactured by TE Connectivity ALCOSWITCH Switches. This component features a 16mm circular panel cutout, dual-circuit configuration (SPST-NO + SPST-NC), and neon illumination at 110 VAC. The part is classified as obsolete, necessitating identification of active equivalent alternatives that maintain functional and mechanical compatibility for ongoing applications and new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the PBES16L2FR is based on strict equivalence of the following critical parameters:

Mechanical Compatibility:

• Series designation (PBES16)
• Panel mounting configuration (Panel Mount, Front)
• Panel cutout dimensions (Circular - 16.00mm Dia)
• Termination style (Solder, Quick Connect - 0.110" (2.8mm))

Electrical Compatibility:

• Circuit configuration (SPST-NO + SPST-NC)
• Switch function (On-Off, Off-On)
• Reset operation (Twist)
• Current rating (3A AC, 220mA DC)
• Voltage rating - AC (125 V)
• Ingress protection (IP65)
• Operating temperature range (-25°C ~ 55°C)

Functional Difference: The primary distinction between the main part and its substitute lies in the illumination system. The PBES16L2FR uses neon illumination at 110 VAC, while the substitute PBES16L2DR uses LED illumination at 12-24 VAC/DC. This difference does not affect the core switching functionality but impacts circuit design for the illumination circuit.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The PBES16L2DR is a direct mechanical and electrical substitute for the PBES16L2FR for the core switching function. All mechanical parameters, circuit configuration, current ratings, voltage ratings, and environmental specifications are identical. The components share the same panel cutout dimensions, termination style, and operational characteristics.

Compliance Considerations:

The PBES16L2DR is an active product with documented RoHS3 compliance and REACH unaffected status, whereas the PBES16L2FR is obsolete with no compliance documentation provided. For applications requiring regulatory compliance with modern environmental standards, the PBES16L2DR is the appropriate selection.

Illumination Circuit Redesign:

The substitution requires modification of the illumination circuit. The PBES16L2FR operates with 110 VAC neon illumination, while the PBES16L2DR requires 12-24 VAC/DC LED illumination. The switching contacts themselves remain functionally identical; only the illumination power supply circuit requires redesign to accommodate the different voltage and current requirements of the LED illumination system.

Inventory and Availability:

The PBES16L2DR is currently in active production with 714 units in stock, providing supply continuity for applications transitioning from the obsolete PBES16L2FR.

Frequently Asked Questions (FAQ)

Q: Can the PBES16L2DR be used as a direct drop-in replacement for the PBES16L2FR?

A: The PBES16L2DR is mechanically and electrically compatible for the switching function. However, the illumination circuit requires modification due to different voltage and illumination technology requirements (110 VAC neon versus 12-24 VAC/DC LED).

Q: What are the key mechanical compatibility factors?

A: Both parts share identical panel mounting configuration, 16mm circular cutout dimensions, twist reset operation, and 0.110" (2.8mm) quick connect termination. They are mechanically interchangeable in the panel assembly.

Q: Are the electrical switching characteristics identical?

A: Yes. Both parts feature SPST-NO + SPST-NC circuit configuration, 3A AC and 220mA DC current ratings, 125V AC voltage rating, and identical operating temperature range (-25°C ~ 55°C).

Q: What is the primary difference between these parts?

A: The illumination system differs. The PBES16L2FR uses neon illumination at 110 VAC, while the PBES16L2DR uses LED illumination at 12-24 VAC/DC. The switching contacts and mechanical structure are identical.

Q: Does the PBES16L2DR meet current regulatory requirements?

A: Yes. The PBES16L2DR is RoHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.

Q: What packaging is provided with the PBES16L2DR?

A: The PBES16L2DR is supplied in box packaging.

Q: Are both parts suitable for IP65 applications?

A: Yes. Both the PBES16L2FR and PBES16L2DR provide IP65 ingress protection (dust tight, water resistant).
