Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TE Connectivity 1393546-1 is determined by alignment of the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPST (Single Pole Single Throw)
• Number of positions: 1
• Mounting type: Through Hole
• Termination style: PC Pin
• Pitch spacing: 0.100" (2.54mm), Full
• Actuator level: Raised

Functional Parameters:

• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• ECCN classification: EAR99
• HTSUS code: 8536.50.9065

The Würth Elektronik 418117270901 satisfies all mandatory compatibility parameters and maintains equivalent MSL, ECCN, and HTSUS classifications. This part is classified as active and available in production quantities.

Parameter Comparison

Engineering Selection Recommendations

The Würth Elektronik 418117270901 is a suitable substitute for the obsolete TE Connectivity 1393546-1 based on the following engineering criteria:

Product Status Alignment: The substitute part is classified as active and available in production quantities (6,746 pieces in stock), ensuring long-term supply continuity compared to the obsolete status of the original part.

Functional Compatibility: Both parts share identical circuit configuration (SPST), position count (1), mounting type (through hole), termination style (PC pin), and pitch spacing (0.100" / 2.54mm). These parameters ensure direct functional equivalence in PCB layouts and electrical circuits.

Regulatory and Compliance Alignment: Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9065) classifications, ensuring equivalent export control and tariff treatment. The substitute part carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements.

Physical Considerations: The substitute part exhibits a reduced height above board (0.189" versus 0.319"), which may require mechanical clearance verification in existing enclosure designs. The actuator type differs (slide standard versus unspecified), which may affect user interface feel but does not impact electrical function.

Electrical Specifications: The substitute part provides defined electrical ratings (25mA at 24VDC) and operational temperature range (-40°C to 85°C), offering greater specification transparency than the original part. Mechanical life (5,000 cycles) and electrical life (2,000 cycles) are documented for reliability assessment.

Frequently Asked Questions (FAQ)

Q: Can the Würth Elektronik 418117270901 be used as a direct replacement for the TE Connectivity 1393546-1 in existing PCB designs?

A: Yes, the substitute part is electrically and mechanically compatible for PCB integration. Both parts share identical pitch spacing (0.100" / 2.54mm), mounting type (through hole), termination style (PC pin), and circuit configuration (SPST, 1 position). Physical clearance must be verified due to the reduced height above board (0.189" versus 0.319").

Q: What is the primary reason for substitution?

A: The TE Connectivity 1393546-1 is classified as obsolete. The Würth Elektronik 418117270901 is an active product with documented production availability, ensuring supply continuity for new production and field repairs.

Q: Are there differences in electrical performance between these parts?

A: The substitute part provides defined electrical specifications (25mA at 24VDC) and operating temperature range (-40°C to 85°C). The original part does not specify these parameters. Both parts maintain equivalent ECCN and HTSUS classifications.

Q: Does the substitute part meet current environmental regulations?

A: Yes, the Würth Elektronik 418117270901 is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original part does not specify these certifications.

Q: What is the difference in actuator type between these parts?

A: The substitute part features a slide (standard) actuator, while the original part does not specify actuator type. Both maintain a raised actuator level. The actuator type difference affects user interface feel but does not impact electrical function or circuit behavior.

Q: Are there packaging differences?

A: The substitute part is supplied in tube packaging. Original packaging specifications for the TE Connectivity part are not provided. Packaging format may affect handling and assembly processes.

Q: What is the mechanical life expectancy of the substitute part?

A: The Würth Elektronik 418117270901 is rated for 5,000 mechanical cycles and 2,000 electrical cycles. The original part does not specify mechanical or electrical life ratings.

Q: Is the reduced height above board a concern for existing designs?

A: The substitute part height (0.189" / 4.80mm) is lower than the original (0.319" / 8.10mm). Mechanical clearance verification is required for existing enclosure designs, particularly where vertical space is constrained or where the original height was a design consideration.
