PBS8MZRES Equivalent & Substitute Parts

Part Overview

The PBS8MZRES is a pushbutton switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Standard Surface Mount, Right Angle SPDT (Single Pole Double Throw) device with On-Momentary switch function. This component is rated for 0.4VA at 20V AC/DC and features IP67 ingress protection with process sealing. The PBS8MZRES is classified as obsolete, necessitating identification of equivalent substitute components for ongoing design requirements and procurement needs.

Substitute Part Grouping Explanation

Substitution of the PBS8MZRES is based on electrical and mechanical compatibility within the TE Connectivity ALCOSWITCH Switches product family. The primary substitute identified is the PBS9MZRES, which maintains compatibility across the following critical parameters:

Electrical Compatibility Parameters:

• Current Rating: 0.4VA (AC/DC)
• Voltage Rating - AC: 20 V
• Voltage Rating - DC: 20 V

Mechanical Compatibility Parameters:

• Mounting Type: Surface Mount, Right Angle
• Actuator Type: Round, Plunger
• Termination Style: SMD (SMT) Tab
• Ingress Protection: IP67 - Dust Tight, Waterproof
• Operating Temperature Range: -30°C ~ 85°C
• Mechanical Life: 50,000 Cycles

Functional Difference: The PBS9MZRES operates as SPST-NO (Single Pole Single Throw - Normally Open) with Off-Momentary switch function, whereas the PBS8MZRES is SPDT with On-Momentary function. This circuit configuration difference requires circuit-level evaluation for application compatibility.

Parameter Comparison

Engineering Selection Recommendations

The PBS9MZRES serves as the active substitute for the obsolete PBS8MZRES within the TE Connectivity ALCOSWITCH Switches product line. Selection of the PBS9MZRES is supported by the following factors:

Product Status: The PBS9MZRES maintains Active product status, ensuring ongoing availability and manufacturing support, whereas the PBS8MZRES is classified as Obsolete.

Compliance Certifications: The PBS9MZRES achieves ROHS3 Compliant status and is REACH Affected, representing current regulatory compliance standards. The PBS8MZRES meets RoHS Compliant requirements but lacks REACH designation.

Electrical and Mechanical Equivalence: Both components share identical current ratings (0.4VA AC/DC), voltage ratings (20V AC/DC), operating temperature ranges (-30°C ~ 85°C), mechanical life (50,000 cycles), ingress protection (IP67), and termination style (SMD Tab).

Circuit Configuration Consideration: The primary functional difference between these components is the circuit configuration: PBS8MZRES operates as SPDT with On-Momentary function, while PBS9MZRES operates as SPST-NO with Off-Momentary function. Circuit-level compatibility must be evaluated based on specific application requirements.

Packaging Availability: The PBS9MZRES is supplied in Tape & Reel (TR) packaging, whereas the PBS8MZRES was supplied in Cut Tape (CT) packaging. This difference affects procurement and assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the PBS9MZRES directly replace the PBS8MZRES in all applications?

A: Direct replacement depends on circuit configuration requirements. The PBS8MZRES is SPDT with On-Momentary function, while the PBS9MZRES is SPST-NO with Off-Momentary function. Applications requiring SPDT switching logic cannot use the PBS9MZRES without circuit redesign. Applications requiring only SPST-NO switching with Off-Momentary function are compatible.

Q: What are the electrical compatibility parameters between these components?

A: Both components share identical electrical specifications: 0.4VA current rating at 20V AC/DC, operating temperature range of -30°C to 85°C, and 50,000 mechanical life cycles. These parameters establish electrical equivalence for applications where circuit configuration is compatible.

Q: How do the packaging formats differ between PBS8MZRES and PBS9MZRES?

A: The PBS8MZRES is supplied in Cut Tape (CT) packaging, while the PBS9MZRES is supplied in Tape & Reel (TR) packaging. Cut Tape packaging is suitable for lower-volume applications and manual assembly, whereas Tape & Reel packaging is optimized for automated pick-and-place assembly processes.

Q: What is the significance of the ROHS3 compliance on the PBS9MZRES?

A: ROHS3 Compliant status on the PBS9MZRES indicates compliance with the current Restriction of Hazardous Substances Directive, representing updated regulatory requirements. The PBS8MZRES meets RoHS Compliant requirements but does not carry ROHS3 designation.

Q: Are the mechanical and environmental specifications identical between these components?

A: Yes. Both components feature identical mechanical specifications: 50,000 cycle mechanical life, Round Plunger actuator type, SMD Tab termination, and IP67 ingress protection (Dust Tight, Waterproof) with process sealing. Operating temperature ranges are identical at -30°C to 85°C.

Q: What is the base product number relationship between PBS8MZRES and PBS9MZRES?

A: The PBS8MZRES is based on the PBS8M product line, while the PBS9MZRES is based on the PBS9M product line. These represent distinct product families within the TE Connectivity ALCOSWITCH Switches portfolio, with the PBS9M series representing the current active generation.
