TSS11EGPC Equivalent & Substitute Parts

Part Overview

The TSS11EGPC is an active-status slide switch manufactured by TE Connectivity ALCOSWITCH Switches. This SPDT (Single Pole Double Throw) switch is designed for through-hole mounting applications requiring low-voltage, low-current switching operations. The switch features non-shorting contact timing, gold-plated copper contacts, and epoxy-sealed terminals suitable for general-purpose on-off-on switching functions. Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility permits operation within alternative electrical and mechanical parameter ranges.

Substitute Part Grouping Explanation

Substitute parts for the TSS11EGPC are classified based on electrical and mechanical compatibility within the following criteria:

Direct Equivalent Classification: Parts that maintain identical or functionally equivalent electrical specifications (circuit configuration, contact timing, switch function, voltage and current ratings) and mechanical parameters (mounting type, termination style, actuator length, switch travel) are classified as direct equivalents. These parts are interchangeable without circuit redesign.

Similar Classification: Parts that share the same circuit configuration (SPDT), switch function (On-Off-On), and mounting type (through-hole PC pin) but operate at different voltage or current ratings are classified as similar substitutes. These parts require circuit-level evaluation to confirm compatibility with the application's electrical requirements.

The following parameters determine substitution eligibility:

• Circuit configuration (SPDT required)
• Switch function (On-Off-On required)
• Mounting type (Through Hole required)
• Termination style (PC Pin required)
• Voltage rating (must meet or exceed application requirements)
• Current rating (must meet or exceed application requirements)
• Contact timing (non-shorting preferred for sensitive applications)

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (1571982-4): The part number 1571982-4 manufactured by TE Connectivity ALCOSWITCH Switches is a direct equivalent to the TSS11EGPC. Both parts share identical electrical ratings (0.4 VA at 20 V AC/DC), circuit configuration (SPDT), contact timing (non-shorting BBM), mechanical specifications (through-hole PC pin termination, 2.80 mm actuator length, 3.05 mm switch travel), and operating temperature range (-20 to 80 °C). Both parts maintain 60,000 cycles of mechanical and electrical life. The 1571982-4 carries ROHS3 compliance certification, whereas the TSS11EGPC RoHS status is not applicable. This part is suitable for direct substitution without circuit modification. Current inventory for 1571982-4 is 1,475 pieces.

Similar Substitute (500ASSP3M2QE): The part number 500ASSP3M2QE manufactured by E-Switch is classified as a similar substitute. This part exceeds the electrical requirements of the TSS11EGPC with a current rating of 3 A and voltage ratings of 120 V AC and 28 V DC. The circuit configuration (SPDT), switch function (On-Off-On), mounting type (through-hole), and termination style (PC pin) are compatible. However, the 500ASSP3M2QE exhibits reduced mechanical and electrical life (30,000 cycles versus 60,000 cycles), a slightly longer actuator length (3.10 mm versus 2.80 mm), and silver contact finish instead of gold. This part is suitable for applications where higher voltage or current capacity is beneficial, provided the mechanical life reduction is acceptable. Current inventory for 500ASSP3M2QE is 1,256 pieces.

Similar Substitute (ASE1E-2M-10-Z): The part number ASE1E-2M-10-Z manufactured by Nidec Components Corporation is classified as a similar substitute. This part operates at 50 mA and 60 V AC/DC, which exceeds the voltage rating of the TSS11EGPC but operates at lower current. The circuit configuration (SPDT), switch function (On-Off-On), contact timing (non-shorting BBM), mounting type (through-hole), and termination style (PC pin) are compatible. The ASE1E-2M-10-Z features a shorter switch travel (2.20 mm versus 3.05 mm) and significantly reduced electrical life (10,000 cycles versus 60,000 cycles). This part is suitable for low-current applications where the reduced cycle life is acceptable. Current inventory for ASE1E-2M-10-Z is 20,045 pieces.

All substitute parts carry active product status and ROHS3 compliance certification, confirming ongoing manufacturer support and environmental regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can the 1571982-4 be used as a direct replacement for the TSS11EGPC without any circuit modifications?

A: Yes. The 1571982-4 is a direct equivalent with identical electrical specifications (0.4 VA, 20 V AC/DC), circuit configuration (SPDT), contact timing (non-shorting BBM), and mechanical parameters (through-hole PC pin, 2.80 mm actuator, 3.05 mm travel). No circuit redesign is required.

Q: What are the key differences between the TSS11EGPC and the 500ASSP3M2QE?

A: The 500ASSP3M2QE provides higher electrical capacity (3 A versus 0.4 VA; 120 V AC versus 20 V AC) but exhibits reduced mechanical and electrical life (30,000 cycles versus 60,000 cycles). The actuator length is slightly longer (3.10 mm versus 2.80 mm), and the contact finish is silver instead of gold. Substitution is valid for applications requiring higher electrical ratings where reduced cycle life is acceptable.

Q: Is the ASE1E-2M-10-Z suitable for high-cycle applications?

A: No. The ASE1E-2M-10-Z is rated for only 10,000 electrical cycles, compared to 60,000 cycles for the TSS11EGPC. This part is suitable only for low-cycle-count applications. The shorter switch travel (2.20 mm versus 3.05 mm) may also affect actuator feel and mechanical engagement.

Q: What is the significance of contact timing (non-shorting BBM) in switch selection?

A: Non-shorting contact timing (break-before-make) ensures that the moving contact breaks connection with one terminal before making connection with the other. This prevents momentary short circuits and is critical for sensitive electronic circuits. The TSS11EGPC, 1571982-4, and ASE1E-2M-10-Z all feature non-shorting contact timing. The 500ASSP3M2QE contact timing is not specified.

Q: Are all substitute parts RoHS compliant?

A: The 1571982-4, 500ASSP3M2QE, and ASE1E-2M-10-Z all carry ROHS3 compliance certification. The TSS11EGPC RoHS status is listed as not applicable. All parts are suitable for applications requiring environmental regulatory compliance.

Q: What packaging formats are available for these parts?

A: The TSS11EGPC, 1571982-4, and 500ASSP3M2QE are supplied in bulk packaging. The ASE1E-2M-10-Z is supplied in tray packaging. Packaging format selection depends on assembly process requirements and inventory management practices.

Q: Can the TSS11EGPC be substituted with the ASE1E-2M-10-Z in a high-reliability application?

A: Substitution is not recommended for high-reliability applications. The ASE1E-2M-10-Z is rated for only 10,000 electrical cycles compared to 60,000 cycles for the TSS11EGPC. Additionally, the ASE1E-2M-10-Z operates at lower current (50 mA versus 0.4 VA), which may not be suitable if the application requires the full current capacity of the original part.

Q: What is the operating temperature range compatibility across all parts?

A: The TSS11EGPC and 1571982-4 operate from -20 to 80 °C. The 500ASSP3M2QE operates from -30 to 85 °C, providing extended low-temperature performance. The ASE1E-2M-10-Z operates from -20 to 85 °C. All parts are suitable for standard industrial temperature ranges.
