ST23T2M5ZBE Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The ST23T2M5ZBE is a panel-mount toggle switch manufactured by APEM Inc., configured as a DPDT (Double Pole Double Throw) momentary-off-momentary switch rated for 0.4VA at 20V AC/DC. This component features a non-illuminated standard round actuator with solder lug termination and epoxy-sealed terminals for environmental protection.

The ST23T2M5ZBE is classified as obsolete. Locating equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this switch configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ST23T2M5ZBE are identified based on strict electrical and mechanical parameter alignment. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Circuit configuration: DPDT
• Switch function: Mom-Off-Mom
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Bushing thread: 15/32-32
• Operating temperature range: -30°C ~ 85°C
• Electrical life: 40,000 Cycles

Allowable Variations:

• Panel cutout diameter: 11.89mm to 11.91mm (within mechanical tolerance)
• Actuator type: Standard Round or Anti-Rotation (both compatible with panel mount)
• Actuator material finish: Nickel Plated or Chrome Plated (both provide corrosion resistance)
• Ingress protection rating: May vary (IP67 provides enhanced environmental sealing)
• REACH status: May differ based on manufacturer compliance framework

The substitute parts 7205TCWZBE and 7205TPZBE, both manufactured by C&K, meet all critical electrical and mechanical parameters and are therefore direct substitutes for the obsolete ST23T2M5ZBE.

Parameter Comparison

Engineering Selection Recommendations

Both C&K substitute parts (7205TCWZBE and 7205TPZBE) are active products with current manufacturing support, providing supply chain continuity for the obsolete ST23T2M5ZBE. Both substitutes maintain full ROHS3 compliance and identical electrical ratings.

7205TCWZBE Selection Criteria:

• Identical actuator type (Standard Round) to the original ST23T2M5ZBE
• Enhanced ingress protection rating (IP67) for applications requiring dust and moisture sealing
• Active product status ensures long-term availability
• ROHS3 compliant

7205TPZBE Selection Criteria:

• Anti-Rotation actuator type provides mechanical stability in high-vibration environments
• Active product status ensures long-term availability
• ROHS3 compliant
• Suitable for applications where actuator rotation prevention is beneficial

Both parts are electrically and mechanically interchangeable with the ST23T2M5ZBE within the specified operating parameters. Selection between the two C&K alternatives depends on actuator type preference and environmental sealing requirements.

Frequently Asked Questions (FAQ)

Q: Can 7205TCWZBE and 7205TPZBE be used interchangeably with ST23T2M5ZBE?

A: Yes. Both C&K parts meet all critical electrical parameters (DPDT, Mom-Off-Mom, 0.4VA, 20V AC/DC) and mechanical specifications (panel mount, solder lug termination, 15/32-32 bushing thread). The primary difference is actuator type: 7205TCWZBE uses a standard round actuator matching the original, while 7205TPZBE uses an anti-rotation actuator.

Q: What is the difference between the two substitute parts?

A: The 7205TCWZBE features a standard round actuator and includes IP67 ingress protection. The 7205TPZBE features an anti-rotation actuator without specified ingress protection. Both maintain identical electrical ratings and operating temperature ranges.

Q: Are there panel cutout dimension differences?

A: The ST23T2M5ZBE specifies an 11.89mm diameter circular cutout, while both C&K substitutes specify 11.91mm. This 0.02mm difference falls within standard mechanical tolerances for panel-mount switch installations.

Q: Do the substitute parts maintain RoHS compliance?

A: Yes. Both 7205TCWZBE and 7205TPZBE are ROHS3 compliant, matching the compliance status of the original ST23T2M5ZBE.

Q: Which substitute should be selected for environmentally sealed applications?

A: The 7205TCWZBE is rated IP67 (dust tight, waterproof), providing enhanced environmental protection compared to the original part and the 7205TPZBE alternative.

Q: Are both substitutes currently available?

A: Yes. Both 7205TCWZBE and 7205TPZBE are active products with current manufacturing status, ensuring supply chain availability and long-term support.
