Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity ALCOSWITCH 1520175-2 is determined by strict equivalence across the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: DPST (Double Pole Single Throw)
• Switch function: On-Off operation
• Current rating: 16A AC minimum
• Voltage rating: 125V AC minimum
• Actuator type: Standard Round
• Actuator length: Within acceptable mechanical tolerance range (17.04mm reference)

Compliance Parameters:

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

The Carling Technologies DK284-73 satisfies all critical electrical parameters and mechanical requirements for direct substitution. Both components operate identically in DPST on-off applications at 16A/125V AC with standard round actuators of comparable length (17.04mm vs. 17.45mm).

Parameter Comparison

Engineering Selection Recommendations

The Carling Technologies DK284-73 is a direct functional equivalent for the obsolete TE Connectivity ALCOSWITCH 1520175-2 based on the following engineering criteria:

Electrical Equivalence: Both components operate identically as DPST on-off switches rated for 16A at 125V AC. No circuit redesign or electrical recalculation is required for substitution.

Mechanical Compatibility: The standard round actuator design and actuator length variance of 0.41mm (17.04mm vs. 17.45mm) fall within acceptable mechanical tolerance for panel-mounted toggle switch applications. Panel cutout dimensions for the DK284-73 are specified as circular 12.70mm diameter with 15/32-32 bushing thread, providing standard mounting compatibility.

Compliance Enhancement: The DK284-73 carries ROHS3 compliance certification, exceeding the "not applicable" status of the obsolete TE Connectivity component. This substitution improves regulatory compliance for new designs and updated equipment.

Operational Reliability: The DK284-73 is rated for 25,000 electrical cycles with an operating temperature range of -17.8°C to 65.6°C, providing documented performance specifications absent from the obsolete part's data.

Supply Continuity: The DK284-73 maintains active production status with confirmed inventory availability (1104 pieces in stock), ensuring long-term supply reliability compared to the obsolete TE Connectivity component.

Frequently Asked Questions (FAQ)

Q: Can the Carling Technologies DK284-73 replace the TE Connectivity ALCOSWITCH 1520175-2 in existing equipment?

A: Yes. Both components are DPST on-off switches with identical electrical ratings (16A/125V AC) and compatible mechanical specifications. The 0.41mm actuator length difference does not affect functional performance or panel mounting compatibility.

Q: What are the key electrical parameters that determine substitution eligibility?

A: Substitution requires matching circuit configuration (DPST), switch function (on-off), current rating (16A AC minimum), and voltage rating (125V AC minimum). The DK284-73 meets all these criteria.

Q: Does the DK284-73 require different panel cutout dimensions?

A: The DK284-73 specifies a circular 12.70mm diameter panel cutout with 15/32-32 bushing thread. Verify that existing panel mounting holes accommodate these specifications before installation.

Q: What is the difference in actuator length between these components?

A: The TE Connectivity 1520175-2 has a 17.04mm actuator length, while the Carling Technologies DK284-73 has a 17.45mm actuator length. This 0.41mm variance is within acceptable tolerance for standard toggle switch applications and does not affect electrical performance.

Q: Is the DK284-73 compliant with current regulatory standards?

A: Yes. The DK284-73 is ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations. The obsolete TE Connectivity component carries "not applicable" RoHS status.

Q: What is the electrical life rating of the substitute component?

A: The Carling Technologies DK284-73 is rated for 25,000 electrical cycles. The TE Connectivity 1520175-2 electrical life specification is not provided in available documentation.

Q: Are there packaging differences between these components?

A: The TE Connectivity 1520175-2 packaging is listed as "-" (unspecified). The Carling Technologies DK284-73 is supplied in bulk packaging. Confirm packaging requirements for your application.

Q: What is the operating temperature range for the substitute?

A: The Carling Technologies DK284-73 operates from -17.8°C to 65.6°C. The TE Connectivity 1520175-2 operating temperature specification is not provided.
