Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7105SYAV2LE is determined by the following critical parameters:

Primary Compatibility Criteria:

• Circuit configuration: SPDT
• Switch function: Mom-Off-Mom
• Mounting type: Panel Mount, Right Angle, Vertical
• Termination style: PC Pin
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40

Electrical Performance Criteria:

• Current rating: Minimum 5A (AC/DC)
• Voltage rating - AC: Minimum 120V
• Voltage rating - DC: Minimum 28V
• Operating temperature range: -30°C to 85°C or broader

Substitute parts are classified into two categories:

Direct Equivalent: Parts that match all primary compatibility criteria and meet or exceed all electrical performance specifications without derating.

Similar Substitute: Parts that match all primary compatibility criteria but may have reduced electrical ratings or minor mechanical variations (such as actuator type or length). These parts are suitable only when the application's actual electrical requirements are lower than the main part's rated specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - Recommended for Direct Replacement:

The C&K 7105SYAV2RE is the primary direct equivalent. This part maintains identical electrical ratings (5A at 120V AC and 28V DC), mechanical configuration, and operating temperature range as the obsolete 7105SYAV2LE. The 7105SYAV2RE is currently in active production status, ensuring long-term availability. Both parts are RoHS compliant and share the same base product number (7105SY), confirming functional equivalence. This part is suitable for direct substitution without circuit modification.

Similar Substitutes - Application-Dependent Selection:

The E-Switch 100SP4T1B1M7QEH matches the 5A current rating and 120V AC voltage specification of the main part, making it suitable for applications operating at the full electrical specification. This part is currently active and ROHS3 compliant.

The Grayhill Inc. 34ASP41B1M7RT and Electroswitch A127P32DAV2B and A127S1YAV2B are classified as similar substitutes due to reduced electrical ratings (0.4VA to 0.5VA). These parts are suitable only for applications where actual operating current and voltage are significantly lower than the main part's rated specifications. The Electroswitch parts offer extended electrical life (60,000 cycles versus 40,000 cycles) and broader operating temperature ranges (-30°C to 90°C).

Compliance Considerations:

All substitute parts maintain RoHS compliance. The 7105SYAV2RE is the only substitute with confirmed REACH Affected status matching regulatory documentation requirements. For applications requiring specific REACH compliance documentation, the 7105SYAV2RE is the preferred choice.

Frequently Asked Questions (FAQ)

Q: Can the 7105SYAV2RE be used as a direct replacement for the 7105SYAV2LE?

A: Yes. The 7105SYAV2RE is a direct equivalent with identical electrical ratings, mechanical configuration, and operating specifications. No circuit modifications are required.

Q: What is the difference between "Direct Equivalent" and "Similar Substitute" classifications?

A: Direct equivalents match all electrical and mechanical specifications of the main part. Similar substitutes match the mechanical configuration and circuit function but have reduced electrical ratings. Similar substitutes are suitable only when the application's actual electrical requirements are lower than the main part's rated specifications.

Q: Can I use the Grayhill 34ASP41B1M7RT or Electroswitch parts in a 120V AC application?

A: No. The Grayhill part is rated for 20V AC maximum and the Electroswitch parts are rated for 28V AC maximum. These parts cannot be used in applications requiring 120V AC operation.

Q: Are all substitute parts panel mount with the same cutout dimensions?

A: All substitute parts are panel mount with right-angle vertical orientation and 1/4-40 bushing thread. The Electroswitch parts (A127P32DAV2B and A127S1YAV2B) do not specify panel cutout dimensions in the available data. Mechanical verification is required before installation if panel cutout dimensions are critical to your application.

Q: What is the difference between the two Electroswitch parts (A127P32DAV2B and A127S1YAV2B)?

A: Both parts have identical electrical ratings (0.5VA at 28V AC/DC) and operating temperature range (-30°C to 90°C). The primary difference is actuator type: A127P32DAV2B has a flatted actuator with 11.38mm length, while A127S1YAV2B has a standard round actuator with 10.41mm length. Selection depends on panel design and actuator engagement requirements.

Q: Are there inventory considerations for substitute part selection?

A: Current inventory levels are: 7105SYAV2RE (945 pcs), 100SP4T1B1M7QEH (1297 pcs), 34ASP41B1M7RT (996 pcs), A127P32DAV2B (953 pcs), and A127S1YAV2B (897 pcs). All parts are available in quantity.

Q: Do the substitute parts have the same electrical life rating?

A: The 7105SYAV2RE, 100SP4T1B1M7QEH, and 34ASP41B1M7RT are rated for 40,000 cycles. The Electroswitch parts (A127P32DAV2B and A127S1YAV2B) are rated for 60,000 cycles, providing extended operational life.
