Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34DWMSP13B4M2RT is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-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
• Illumination: Non-Illuminated
• Operating temperature range: -30°C to 85°C minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variation Parameters:

• Actuator length (within mechanical fit constraints)
• Ingress protection rating (IP57 or higher acceptable)
• Electrical life cycles (equal or greater acceptable)
• Manufacturer identity
• Inventory availability

The ET01MD1CBE from C&K qualifies as a substitute part based on matching all mandatory parameters while offering enhanced electrical life specifications and equivalent environmental protection.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (34DWMSP13B4M2RT): Select the 34DWMSP13B4M2RT when the original design specification requires the 8.70mm actuator length and IP67 ingress protection rating. This part is active in production with adequate inventory availability.

Substitute Part Selection (ET01MD1CBE): The ET01MD1CBE from C&K is electrically and functionally equivalent for applications where the 6.10mm actuator length accommodates panel mounting requirements. This substitute offers superior electrical life (60,000 cycles versus 30,000 cycles) and significantly higher inventory availability (3551 units in stock). The IP57 rating provides dust protection and waterproofing suitable for most industrial applications, though it does not achieve the full IP67 specification of the primary part.

Both parts maintain ROHS3 compliance and EAR99 export classification. Selection between these parts should be based on mechanical fit requirements (actuator length) and environmental protection specifications (IP67 versus IP57).

Frequently Asked Questions (FAQ)

Q: Can ET01MD1CBE replace 34DWMSP13B4M2RT in all applications?

A: ET01MD1CBE is electrically and functionally equivalent for SPDT switching applications at 0.4VA and 20V. The primary consideration is mechanical fit. The ET01MD1CBE has a 6.10mm actuator length compared to 8.70mm for the 34DWMSP13B4M2RT. Verify that your panel cutout and mechanical assembly accommodate the shorter actuator. Additionally, the ET01MD1CBE provides IP57 protection rather than IP67; confirm this meets your environmental requirements.

Q: What is the difference between IP67 and IP57 ratings?

A: IP67 provides complete dust protection and temporary immersion in water up to 1 meter for 30 minutes. IP57 provides dust protection (limited ingress) and water jet protection from any direction. For most industrial control applications, IP57 is sufficient. Select IP67 only if your application requires complete dust sealing or sustained water immersion.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant and classified as EAR99 for export purposes. The 34DWMSP13B4M2RT is REACH Unaffected, while the ET01MD1CBE is REACH Affected. Verify REACH compliance requirements for your specific application and end market.

Q: What does electrical life rating mean for these switches?

A: Electrical life is measured in switching cycles. The 34DWMSP13B4M2RT is rated for 30,000 cycles, while the ET01MD1CBE is rated for 60,000 cycles. This indicates the ET01MD1CBE has extended operational durability. For applications with frequent switching, the ET01MD1CBE provides longer service life.

Q: Can I use these switches interchangeably on the same PCB?

A: Both parts use PC Pin termination and through-hole mounting, making them mechanically compatible with standard PCB layouts. The primary consideration is the actuator length difference (8.70mm versus 6.10mm), which affects panel mounting fit. Verify your panel cutout dimensions before substitution.

Q: What inventory considerations should I account for?

A: The 34DWMSP13B4M2RT has 632 units in stock, while the ET01MD1CBE has 3551 units available. If supply chain continuity is a concern, the ET01MD1CBE offers significantly higher availability for sustained production requirements.
