TPD11FGPC0 Equivalent & Substitute Parts

Part Overview

The TPD11FGPC0 is a pushbutton switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Single Pole Double Throw (SPDT) device with a rated capacity of 0.4VA at 20V. This through-hole mounted switch features a round plunger actuator with momentary on-off functionality and is designed for standard applications requiring reliable electromechanical switching.

The TPD11FGPC0 is classified as obsolete. Locating equivalent or substitute components is necessary to support ongoing maintenance, repair, and new design requirements where this part number is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPD11FGPC0 is evaluated based on the following critical parameters that must align for functional compatibility:

Mandatory Matching Parameters:

• Manufacturer: TE Connectivity ALCOSWITCH Switches
• Series: TP
• Mounting Type: Through Hole
• Switch Function: On-Mom (Momentary)
• Current Rating: 0.4VA (AC/DC)
• Voltage Rating: 20V (AC and DC)
• Actuator Type: Round, Plunger
• Termination Style: PC Pin
• Operating Temperature Range: -30°C to 65°C

Allowable Variation:

• Circuit Configuration: SPDT to DPDT (increased switching capability)
• Electrical Life: 100,000 cycles to 80,000 cycles (acceptable reduction for equivalent function)
• Product Status: Obsolete to Active (preferred for availability)

The TPD21RGPC0 qualifies as a substitute because it maintains all mandatory parameters while offering enhanced circuit capability (DPDT versus SPDT) and active product status, ensuring continued availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

The TPD21RGPC0 is the designated substitute for the obsolete TPD11FGPC0 based on the following engineering criteria:

Product Status and Supply Chain: The TPD11FGPC0 is classified as obsolete, creating supply chain risk for new production and field replacements. The TPD21RGPC0 maintains active product status with TE Connectivity ALCOSWITCH Switches, ensuring continued availability and support.

Electrical and Mechanical Compatibility: Both components share identical electrical ratings (0.4VA, 20V AC/DC), mechanical mounting (through-hole PC pin termination), and operational characteristics (momentary function, -30°C to 65°C operating range). The TPD21RGPC0 provides DPDT circuit configuration compared to the SPDT of the TPD11FGPC0, offering expanded switching capability without compromising the original application requirements.

Compliance and Certification: Both parts carry identical ECCN (EAR99) and HTSUS (8536.50.9031) classifications, ensuring regulatory consistency. RoHS status and REACH compliance remain equivalent between the two components.

Electrical Life Consideration: The TPD21RGPC0 specifies 80,000 electrical cycles compared to 100,000 cycles for the TPD11FGPC0. This reduction remains within acceptable engineering tolerance for standard pushbutton switch applications and does not compromise functional reliability for typical use cases.

Frequently Asked Questions (FAQ)

Q: Can the TPD21RGPC0 directly replace the TPD11FGPC0 in existing designs?

A: Yes. The TPD21RGPC0 maintains identical mounting, electrical ratings, and operational characteristics. The DPDT configuration provides additional switching capability beyond the original SPDT requirement, making it functionally compatible for applications designed around the TPD11FGPC0.

Q: What is the primary difference between these two components?

A: The TPD11FGPC0 is configured as SPDT (Single Pole Double Throw), while the TPD21RGPC0 is DPDT (Double Pole Double Throw). The DPDT configuration provides two independent switching poles instead of one, offering greater circuit flexibility without changing electrical ratings or physical form factor.

Q: Does the reduction in electrical life from 100,000 to 80,000 cycles affect reliability?

A: The electrical life specification indicates the number of switching cycles under rated conditions before performance degradation. For standard pushbutton applications, 80,000 cycles remains sufficient for typical duty cycles. Applications requiring extended cycle life should evaluate specific usage patterns against the provided specifications.

Q: Are the physical dimensions and panel cutout requirements identical?

A: Both components share identical through-hole mounting and PC pin termination. Panel cutout dimensions are not specified in the provided technical data for either component. Mechanical drawings should be consulted to confirm physical compatibility in specific enclosure designs.

Q: What is the packaging difference between these parts?

A: The TPD11FGPC0 is supplied with standard packaging, while the TPD21RGPC0 is supplied in bulk packaging. This difference affects order quantities and handling but does not impact component functionality or electrical performance.

Q: Are there any compliance or regulatory differences between these components?

A: No. Both components carry identical ECCN (EAR99) and HTSUS (8536.50.9031) classifications. RoHS applicability and REACH status are equivalent, ensuring regulatory consistency in design transitions.
