TPD11FGRA0 Equivalent & Substitute Parts

Part Overview

The TPD11FGRA0 is a pushbutton switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Standard SPDT (Single Pole Double Throw) device with On-Momentary switch function. This component is rated for 0.4VA at 20V AC/DC with a through-hole, right-angle mounting configuration and round plunger actuator. The TPD11FGRA0 is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure supply chain availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete TPD11FGRA0 is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: SPDT
• Switch function: On-Momentary
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Electrical life: 100,000 cycles

Mechanical Equivalence Criteria:

• Mounting type: Through Hole, Right Angle
• Actuator type: Round, Plunger
• Termination style: PC Pin
• Operating temperature range: -30°C ~ 65°C
• Base product series: TPD11

Compliance Equivalence Criteria:

• ECCN classification: EAR99
• HTSUS code: 8536.50.9031
• RoHS status: Not applicable
• REACH status: Vendor Undefined

The TPD11FGRA2 meets all electrical, mechanical, and compliance requirements for direct substitution. The only difference is the actuator color (Red versus Black) and product status (Active versus Obsolete), neither of which affects functional performance or circuit compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TPD11FGRA2 is the direct functional equivalent for the obsolete TPD11FGRA0. Selection of the TPD11FGRA2 is supported by the following factors:

Product Status: The TPD11FGRA2 maintains Active product status, ensuring continued availability and manufacturer support. The TPD11FGRA0 is classified as Obsolete, creating supply chain risk for new production and field service applications.

Electrical and Mechanical Equivalence: All critical electrical parameters (circuit configuration, current rating, voltage rating, electrical life) and mechanical parameters (mounting type, actuator type, termination style, operating temperature range) are identical between the two components.

Compliance Alignment: Both components share identical ECCN (EAR99) and HTSUS (8536.50.9031) classifications, ensuring regulatory and trade compliance consistency.

Packaging Consideration: The TPD11FGRA2 is supplied in Bulk packaging, whereas the TPD11FGRA0 packaging specification is not provided. Bulk packaging is standard for through-hole components and presents no compatibility issues for PCB assembly processes.

Visual Differentiation: The actuator color difference (Red for TPD11FGRA2 versus Black for TPD11FGRA0) provides visual distinction on the assembled board but does not affect electrical performance or circuit function.

Frequently Asked Questions (FAQ)

Q: Can the TPD11FGRA2 be used as a direct replacement for the TPD11FGRA0 in existing designs?

A: Yes. The TPD11FGRA2 is electrically and mechanically equivalent to the TPD11FGRA0. All critical parameters including circuit configuration (SPDT), switch function (On-Momentary), current rating (0.4VA AC/DC), voltage rating (20V), mounting type (Through Hole, Right Angle), and operating temperature range (-30°C ~ 65°C) are identical. The component can be substituted without design modification.

Q: What is the difference between TPD11FGRA0 and TPD11FGRA2?

A: The primary difference is product status: TPD11FGRA0 is Obsolete while TPD11FGRA2 is Active. Additionally, the actuator color differs (Black versus Red). All electrical and mechanical specifications are identical. The color difference is cosmetic and does not affect circuit performance.

Q: Why is the TPD11FGRA0 listed as Obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and support for this component. The TPD11FGRA2 is the active equivalent and is recommended for all new designs and field replacements to ensure supply chain continuity.

Q: Are there any compatibility issues with PCB assembly when switching from TPD11FGRA0 to TPD11FGRA2?

A: No compatibility issues exist. Both components use identical Through Hole, Right Angle mounting with PC Pin termination. The TPD11FGRA2 packaging (Bulk) is standard for through-hole components and compatible with all standard PCB assembly processes.

Q: Does the red actuator color of the TPD11FGRA2 affect circuit function compared to the black actuator of the TPD11FGRA0?

A: No. Actuator color is a visual identifier only and does not affect electrical performance, switching characteristics, or circuit compatibility. The functional behavior of the switch remains identical.

Q: What is the electrical life rating for both components?

A: Both the TPD11FGRA0 and TPD11FGRA2 are rated for 100,000 electrical cycles, ensuring equivalent operational longevity in switching applications.

Q: Are both components RoHS compliant?

A: RoHS status for both components is listed as Not Applicable, indicating that RoHS compliance requirements do not apply to these components under current regulations.
