PBES16L2ER Equivalent & Substitute Parts

Part Overview

The PBES16L2ER is a panel-mount illuminated pushbutton switch manufactured by TE Connectivity ALCOSWITCH Switches. This switch features a 16mm circular panel cutout, dual-circuit configuration (SPST-NO + SPST-NC), twist reset operation, and 120 VAC LED illumination. The part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete PBES16L2ER is determined by strict equivalence across the following critical parameters:

Mechanical Compatibility:

• Panel cutout dimensions (16.00mm circular)
• Mounting type (Panel Mount, Front)
• Termination style (Solder, Quick Connect - 0.110")

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 voltage specification. The PBES16L2ER operates at 120 VAC illumination, while the substitute operates at 12-24 VAC/DC illumination. This difference requires circuit-level evaluation during integration.

Engineering Selection Recommendations

The PBES16L2DR is the active equivalent substitute for the obsolete PBES16L2ER. Both parts share identical mechanical and electrical specifications across all critical parameters including panel cutout dimensions, circuit configuration, current and voltage ratings, termination style, ingress protection, and operating temperature range.

The PBES16L2DR offers the following advantages for new designs and production continuity:

Product Status: The PBES16L2DR maintains active product status with confirmed inventory availability (714 Pcs), ensuring supply chain continuity and long-term availability compared to the obsolete PBES16L2ER.

Regulatory Compliance: The PBES16L2DR is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The ECCN classification (EAR99) provides clear export control status for international applications.

Illumination Voltage Consideration: The primary design consideration is the illumination voltage difference. The PBES16L2ER operates at 120 VAC illumination, while the PBES16L2DR operates at 12-24 VAC/DC illumination. This requires verification that the control circuit can supply the appropriate illumination voltage for the substitute part.

Frequently Asked Questions (FAQ)

Q: Can the PBES16L2DR directly replace the PBES16L2ER in existing assemblies?

A: Mechanical and electrical switch specifications are identical. Direct physical replacement is possible. However, the illumination voltage requirement differs (120 VAC versus 12-24 VAC/DC), requiring verification that the control circuit can supply the appropriate illumination voltage for the substitute part.

Q: What are the key compatibility criteria for substitution?

A: Substitution is based on equivalence across mechanical dimensions (16mm circular panel cutout), circuit configuration (SPST-NO + SPST-NC), electrical ratings (3A AC, 220mA DC, 125V AC), termination style (Solder, Quick Connect - 0.110"), ingress protection (IP65), and operating temperature range (-25°C ~ 55°C).

Q: Are there packaging differences between the main part and substitute?

A: The PBES16L2ER packaging is not specified in the available data. The PBES16L2DR is supplied in Box packaging.

Q: What is the inventory status for the substitute part?

A: The PBES16L2DR has 714 Pcs of new original stock available, providing adequate supply for production requirements.

Q: Does the PBES16L2DR meet current environmental standards?

A: Yes, the PBES16L2DR is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

Q: What is the primary design consideration when substituting these parts?

A: The illumination voltage specification is the primary design consideration. Verify that the control circuit can supply 12-24 VAC/DC for the PBES16L2DR, as opposed to 120 VAC required for the PBES16L2ER.
