TPA11CGPC2 Equivalent & Substitute Parts

Part Overview

The TPA11CGPC2 is a pushbutton switch manufactured by TE Connectivity ALCOSWITCH Switches, classified as a Standard SPST-NO (Single Pole Single Throw - Normally Open) momentary contact switch. This component features a round plunger actuator with a red cap, rated for 0.4VA at 20V AC/DC, and is designed for through-hole mounting on printed circuit boards.

The TPA11CGPC2 carries an Obsolete product status. Identification of equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production and repair requirements for systems utilizing this switch architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPA11CGPC2 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary contact)
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC

Mechanical Equivalence Requirements:

• Mounting type: Through Hole
• Actuator type: Round, Plunger
• Termination style: PC Pin
• Operating temperature range: -30°C ~ 65°C
• Electrical life: 100,000 Cycles

Series Compatibility:

• Base product number: TPA11
• Manufacturer: TE Connectivity ALCOSWITCH Switches

The substitute part TPA11CGPC6 satisfies all electrical and mechanical equivalence criteria. The primary distinction between these parts is the actuator cap color (red versus blue) and product status (Obsolete versus Active).

Parameter Comparison

Engineering Selection Recommendations

The TPA11CGPC6 serves as a direct functional substitute for the TPA11CGPC2 based on electrical and mechanical parameter equivalence. Both components share identical circuit configuration, voltage and current ratings, mounting methodology, and operational temperature specifications.

The TPA11CGPC6 carries an Active product status, ensuring ongoing availability and manufacturing support. This status transition from Obsolete to Active represents the primary advantage of substitution.

The actuator cap color difference (red to blue) is a cosmetic distinction that does not affect electrical performance or mechanical function. Design documentation and assembly procedures should be updated to reflect this visual change if color-coding is used for circuit identification or operator interface purposes.

The RoHS compliance designation differs between the two parts. The TPA11CGPC2 is explicitly ROHS3 Compliant, while the TPA11CGPC6 lists RoHS status as Not applicable. Compliance requirements for the target application must be evaluated independently to determine if this difference presents a constraint on substitution.

Frequently Asked Questions (FAQ)

Q: Can the TPA11CGPC6 be used as a direct replacement for the TPA11CGPC2 in existing circuit designs?

A: Yes. The TPA11CGPC6 is electrically and mechanically equivalent to the TPA11CGPC2. Both components feature identical SPST-NO circuit configuration, 0.4VA current rating at 20V AC/DC, through-hole mounting, and PC pin termination. No circuit modifications are required for substitution.

Q: What is the significance of the different actuator cap colors?

A: The actuator cap color (red on TPA11CGPC2, blue on TPA11CGPC6) is a visual identifier only and does not affect electrical performance or mechanical operation. If the design uses color-coding for operator interface or circuit identification, assembly documentation and labeling procedures must be updated accordingly.

Q: Why is the TPA11CGPC2 listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production of this part number. The TPA11CGPC6 is the active equivalent, ensuring continued availability and manufacturing support for applications requiring this switch type.

Q: Are there any differences in packaging between these two parts?

A: The TPA11CGPC2 is packaged individually, while the TPA11CGPC6 is supplied in Bulk packaging. Both parts are identical in component form and function; packaging differences relate only to order quantity and delivery format.

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

A: Substitution is determined by equivalence across circuit configuration (SPST-NO), switch function (Off-Mom), electrical ratings (0.4VA at 20V AC/DC), mounting type (Through Hole), actuator type (Round Plunger), termination style (PC Pin), operating temperature range (-30°C ~ 65°C), and electrical life (100,000 Cycles). All these parameters are identical between the TPA11CGPC2 and TPA11CGPC6.

Q: Should RoHS compliance differences affect the substitution decision?

A: RoHS compliance requirements are application-specific and regulatory-dependent. The TPA11CGPC2 is ROHS3 Compliant, while the TPA11CGPC6 lists RoHS status as Not applicable. Applications subject to RoHS regulations must independently verify compliance requirements before finalizing substitution decisions.
