Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AM50646C33-A is determined by the following critical parameters:

Primary Matching Criteria:

• Circuit configuration: SPDT
• Switch function: On-Mom (momentary operation)
• Current rating: 6A minimum at 125V AC
• Actuator type: Lever with roller
• Mounting type: Chassis mount
• Termination style: Quick connect 0.187" (4.7mm)

Secondary Compatibility Factors:

• Operating temperature range compatibility
• Mechanical life rating
• Electrical life rating (where specified)
• Moisture sensitivity level

The substitute part TFS06SA1040C manufactured by C&K meets all primary matching criteria. Both components share identical circuit configuration, switch function, current and voltage ratings, actuator type, mounting method, and termination style. This alignment establishes functional equivalence for direct replacement applications.

Parameter Comparison

Engineering Selection Recommendations

The TFS06SA1040C represents a functionally equivalent substitute for the obsolete AM50646C33-A based on matching electrical specifications, circuit configuration, and mechanical interface parameters. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity.

Compliance Considerations: Both components maintain REACH Unaffected status and identical moisture sensitivity classification (MSL 1 - Unlimited), supporting equivalent regulatory compliance in applications requiring these certifications.

Operational Differences: The TFS06SA1040C exhibits a higher operating force requirement (130gf versus 30gf) and operates within a narrower temperature range (-40°C to 85°C versus -25°C to 105°C). Applications requiring operation at temperatures above 85°C or below -40°C, or those with mechanical constraints limiting actuation force to below 130gf, may require additional evaluation.

Packaging and Availability: The TFS06SA1040C is supplied in box packaging with current inventory availability of 1,578 pieces, compared to the AM50646C33-A with 1,059 pieces in stock. The active product status of the substitute ensures continued procurement capability.

Frequently Asked Questions (FAQ)

Q: Can TFS06SA1040C directly replace AM50646C33-A in existing applications?

A: Direct replacement is supported for applications where the operating force requirement of 130gf is acceptable and operating temperatures remain within the -40°C to 85°C range. The identical circuit configuration, current/voltage ratings, actuator type, mounting method, and termination style ensure mechanical and electrical compatibility.

Q: What is the significance of the operating force difference between these parts?

A: The AM50646C33-A requires 30gf actuation force, while the TFS06SA1040C requires 130gf. This difference affects the mechanical effort needed to actuate the switch. Applications with limited actuation force capability or requiring minimal operator effort should account for this parameter.

Q: Are there temperature range limitations when substituting?

A: The AM50646C33-A operates from -25°C to 105°C, while the TFS06SA1040C operates from -40°C to 85°C. Applications requiring operation above 85°C cannot use the TFS06SA1040C. Applications requiring operation below -40°C cannot use the TFS06SA1040C but can use the AM50646C33-A if inventory is available.

Q: Do both parts use the same termination connector?

A: Yes. Both components use Quick Connect - 0.187" (4.7mm) termination, ensuring identical connector compatibility and eliminating the need for harness or terminal modifications.

Q: What is the difference in product status, and why does it matter?

A: The AM50646C33-A is classified as obsolete, indicating discontinued manufacturing. The TFS06SA1040C is active production, ensuring ongoing availability and supply chain reliability for future procurement needs.

Q: Are regulatory certifications equivalent between these parts?

A: Both components maintain identical REACH Unaffected status and MSL 1 (Unlimited) moisture sensitivity classification, supporting equivalent compliance in regulated applications.
