Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34DWMSP32B4M2RT is determined by strict equivalence across the following parameters:

Critical Parameters (Must Match Exactly):

• Circuit configuration: SPDT
• Switch function: On-Off-On
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Through Hole
• Termination style: PC Pin

Important Parameters (Must Match or Exceed):

• Operating temperature range: -30°C to 85°C minimum
• Electrical life: 30,000 cycles minimum
• RoHS compliance status

Non-Critical Parameters (May Vary):

• Actuator length
• Actuator material finish (brass chrome-plated vs. brass nickel-plated)
• Ingress protection rating (if application does not require IP67)
• Packaging format (bulk vs. standard)
• Manufacturer identity

The substitute part TL39P005000 meets all critical and important parameters and is therefore qualified as an equivalent component.

Engineering Selection Recommendations

Primary Part Selection (34DWMSP32B4M2RT): Select the Grayhill 34DWMSP32B4M2RT when IP67 ingress protection is a design requirement or when the 6.10mm actuator length is specified in the mechanical layout. This part carries RoHS Compliant certification and is actively produced with adequate inventory.

Substitute Part Selection (TL39P005000): The APEM TL39P005000 is electrically and functionally equivalent and qualifies as a direct substitute when:

• IP67 protection is not required by the application
• The 5.30mm actuator length accommodates the mechanical design
• ROHS3 compliance satisfies regulatory requirements
• Bulk packaging is acceptable for procurement

Both parts meet identical electrical specifications (SPDT, 0.4VA, 20V AC/DC, 30,000 cycle life) and share the same termination style (PC Pin through-hole). Both are RoHS compliant and REACH unaffected. Selection between these parts should be based on mechanical fit (actuator length), environmental protection requirements (IP67), and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can TL39P005000 replace 34DWMSP32B4M2RT in all applications?

A: TL39P005000 is electrically and functionally equivalent for SPDT on-off-on switching at 0.4VA and 20V. However, verify that the 5.30mm actuator length fits your mechanical design (versus 6.10mm on the original part) and confirm whether IP67 ingress protection is required. If IP67 is mandatory, the 34DWMSP32B4M2RT is the specified choice.

Q: What are the key electrical parameters that must match for substitution?

A: The following parameters must be identical: circuit configuration (SPDT), switch function (On-Off-On), current rating (0.4VA AC/DC), voltage rating (20V AC and DC), mounting type (Through Hole), and termination style (PC Pin). These parameters define functional compatibility.

Q: Are there differences in reliability between these parts?

A: Both parts specify 30,000 electrical cycles and operate across -30°C to 85°C. The primary difference is actuator material finish (chrome-plated versus nickel-plated brass), which does not affect electrical performance. Both use epoxy sealed terminals.

Q: Does packaging format affect part compatibility?

A: No. Packaging format (standard versus bulk) affects procurement and handling but does not affect electrical or mechanical compatibility. The TL39P005000 is supplied in bulk packaging, while 34DWMSP32B4M2RT uses standard packaging.

Q: Are both parts RoHS compliant?

A: Yes. The 34DWMSP32B4M2RT is RoHS Compliant, and the TL39P005000 is ROHS3 Compliant. Both meet RoHS requirements and are REACH unaffected.

Q: What is the significance of the 0.8mm actuator length difference?

A: The 0.8mm difference (6.10mm versus 5.30mm) may affect panel cutout clearance and actuator engagement depth. Verify mechanical fit in your specific application before substitution. If the original 6.10mm length is critical to your design, use the 34DWMSP32B4M2RT.
