TS01ASE Slide Switch SPDT Equivalent & Substitute Parts

Part Overview

The TS01ASE is an active SPDT (Single Pole Double Throw) slide switch manufactured by C&K, rated for 3A at 120V AC and 28V DC. This through-hole, right-angle mounted component features silver-plated contacts, epoxy sealed terminals, and operates across -30°C to 85°C. With 60,000 electrical cycles and ROHS3 compliance, it serves general-purpose switching applications requiring reliable on-on functionality.

Substitute parts become necessary when addressing supply constraints, lead time requirements, or specific inventory availability while maintaining equivalent electrical and mechanical performance within the defined parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment across the following critical parameters:

Primary Criteria (Must Match):

• Circuit configuration: SPDT
• Switch function: On-On
• Mounting type: Through Hole, Right Angle
• Termination style: PC Pin
• RoHS compliance: ROHS3 Compliant
• Product status: Active

Secondary Criteria (Must Meet or Exceed):

• Current rating: Minimum 3A (AC/DC)
• Voltage rating - AC: Minimum 120V
• Voltage rating - DC: Minimum 28V
• Operating temperature range: Must encompass or match -30°C to 85°C
• Electrical life: Minimum 60,000 cycles

Acceptable Variations:

• Contact material and finish (silver, copper alloy, gold acceptable)
• Actuator material (polyamide, polybutylene terephthalate acceptable)
• Actuator length within ±0.5mm tolerance
• Switch travel distance: 3.05mm standard

Parameter Comparison

Engineering Selection Recommendations

48BFSP1M6QT (Grayhill Inc.): This part meets primary substitution criteria with matching SPDT on-on configuration, 3A current rating, 125V AC rating, and identical mounting specifications. Operating temperature range and switch travel distance align with TS01ASE. However, electrical life is rated at 30,000 cycles, which is 50% lower than the primary part. This substitute is suitable for applications where cycle count requirements do not exceed 30,000 operations. All parts maintain ROHS3 compliance and active product status.

1571984-1 (TE Connectivity ALCOSWITCH): This part does not qualify as a direct substitute. While it maintains SPDT configuration, on-on function, through-hole right-angle mounting, and PC pin termination, the current rating of 0.4VA and voltage ratings of 20V AC/DC fall below the TS01ASE specifications. The operating temperature range (-20°C to 80°C) does not fully encompass the primary part's lower temperature limit. This part is not recommended for direct replacement in applications requiring 3A at 120V AC.

Frequently Asked Questions (FAQ)

Q: Can 48BFSP1M6QT replace TS01ASE in all applications?

A: 48BFSP1M6QT is suitable for applications where electrical cycle life does not exceed 30,000 operations. If your application requires 60,000 cycles or higher, this substitute is not appropriate. Verify your actual cycle count requirements before selection.

Q: Why is 1571984-1 listed if it does not meet specifications?

A: 1571984-1 is provided for reference to demonstrate non-qualifying substitutes. Its lower current and voltage ratings make it unsuitable for direct replacement in TS01ASE applications. It should not be selected as an equivalent part.

Q: Are there mechanical compatibility concerns between TS01ASE and 48BFSP1M6QT?

A: Both parts share identical switch travel distance (3.05mm), actuator length (3.10mm), and through-hole right-angle mounting configuration. Mechanical compatibility is confirmed for PCB layout and mounting hole patterns.

Q: What is the impact of different contact materials?

A: TS01ASE uses silver contacts; 48BFSP1M6QT uses copper alloy contacts. Both materials are acceptable for general switching applications. Contact material selection does not affect substitution eligibility when electrical ratings are met.

Q: Do temperature range differences affect substitution?

A: TS01ASE operates -30°C to 85°C; 48BFSP1M6QT matches this range exactly. 1571984-1 operates -20°C to 80°C, which does not cover the full lower temperature specification of TS01ASE. Verify your application's temperature requirements before selection.
