Substitute Part Grouping Explanation

Substitution eligibility for toggle switches is determined by strict equivalence across electrical and mechanical parameters. The following criteria establish whether a part qualifies as a direct substitute for the 34DWMSP33B4M2RT:

Mandatory Matching Parameters:

• 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
• Actuator type: Standard Round
• Operating temperature range: -30°C to 85°C minimum
• Electrical life: 30,000 cycles minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Actuator length (mechanical dimension affecting panel interface)
• Actuator material finish (brass chrome-plated vs. brass nickel-plated)
• Ingress protection rating (IP67 vs. unspecified)
• Manufacturer identity and series designation

The substitute part TL39P005000 (APEM Inc.) meets all mandatory electrical and mechanical criteria, confirming functional interchangeability in the 34DWMSP33B4M2RT application.

Engineering Selection Recommendations

Primary Part: 34DWMSP33B4M2RT

The 34DWMSP33B4M2RT remains the specified component when the following conditions apply:

• Actuator length of 8.70mm is required for panel interface geometry
• IP67 ingress protection specification is mandatory
• Chrome-plated actuator material is required for corrosion resistance in specific environments
• Grayhill Inc. supply chain or qualification requirements are in effect

Substitute Part: TL39P005000

The TL39P005000 (APEM Inc.) is functionally equivalent and may be selected when:

• Actuator length of 5.30mm is compatible with panel cutout and mechanical assembly
• Nickel-plated brass actuator material meets application requirements
• Ingress protection specification is not explicitly required beyond sealed terminal design
• APEM Inc. component availability or supply chain advantages are present
• ROHS3 compliance and MSL 1 rating satisfy regulatory and storage requirements

Both parts share identical electrical performance, circuit topology, and thermal operating range. Selection between them is determined by mechanical fit and material finish requirements specific to the end application.

Frequently Asked Questions (FAQ)

Q: Can TL39P005000 directly replace 34DWMSP33B4M2RT in all applications?

A: Electrical and functional replacement is direct. Mechanical compatibility depends on panel cutout dimensions and actuator length tolerance. The TL39P005000 has a shorter actuator (5.30mm vs. 8.70mm), which may affect panel interface geometry. Verify mechanical fit before substitution.

Q: What is the significance of the actuator material difference (chrome-plated vs. nickel-plated)?

A: Both materials provide corrosion resistance on brass substrates. Chrome plating offers enhanced hardness and wear resistance; nickel plating provides cost efficiency and adequate corrosion protection. Selection depends on environmental exposure and durability requirements specific to the application.

Q: Does the absence of IP67 specification on TL39P005000 affect substitution eligibility?

A: Both parts feature epoxy sealed terminals, providing sealed switching functionality. The 34DWMSP33B4M2RT explicitly rates IP67 (dust tight, waterproof). If IP67 certification is a design requirement, the 34DWMSP33B4M2RT is the specified choice. If sealed terminal design alone is sufficient, TL39P005000 is acceptable.

Q: Are electrical ratings identical between the two parts?

A: Yes. Both parts are rated 0.4VA at 20V AC/DC with SPDT On-Off-On configuration, 30,000 electrical cycle life, and -30°C to 85°C operating temperature range.

Q: What packaging considerations apply to these parts?

A: Both parts are supplied in Bulk packaging. Inventory availability: 34DWMSP33B4M2RT (795 Pcs), TL39P005000 (809 Pcs). Moisture Sensitivity Level 1 (Unlimited) applies to both, requiring standard handling without special desiccant storage.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 34DWMSP33B4M2RT and TL39P005000 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components.
