TPF11CGRA0 Equivalent & Substitute Parts

Part Overview

The TPF11CGRA0 is a pushbutton switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Standard Panel Mount, Right Angle, Rear SPST-NO (Single Pole Single Throw - Normally Open) switch. The switch is rated for 0.4VA at 20V AC/DC with an Off-Momentary switch function and features a round plunger actuator with black coloring. The TPF11CGRA0 carries an Obsolete product status. Locating equivalent substitute parts is necessary due to the discontinued nature of this component, ensuring continued availability for maintenance, repair, and production applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TPF11CGRA0 is determined by strict equivalence across the following critical parameters:

Electrical Specifications: The substitute part must maintain identical circuit configuration (SPST-NO), current rating (0.4VA AC/DC), and voltage ratings (20V AC and 20V DC). These parameters ensure the switch operates within the same electrical load envelope.

Mechanical Specifications: The substitute part must feature identical mounting type (Panel Mount, Right Angle, Rear), actuator type (Round, Plunger), termination style (PC Pin), and panel cutout dimensions (Circular - 6.35mm Dia). These parameters ensure physical compatibility with existing panel installations and PCB layouts.

Environmental Specifications: The substitute part must support the same operating temperature range (-30°C ~ 65°C) and electrical life rating (100,000 Cycles). These parameters ensure equivalent reliability and performance longevity.

Switch Function: The substitute part must maintain the Off-Momentary switch function to preserve the intended circuit behavior.

The substitute part 1825100-4 meets all these criteria and is therefore a direct functional and mechanical equivalent.

Selection of 1825100-4 is supported by complete electrical equivalence, mechanical compatibility, improved product status, and enhanced compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can 1825100-4 be used as a direct replacement for TPF11CGRA0 in existing applications?

A: Yes. The 1825100-4 is electrically and mechanically equivalent to the TPF11CGRA0. All critical parameters including circuit configuration (SPST-NO), current rating (0.4VA AC/DC), voltage ratings (20V AC/DC), mounting type (Panel Mount, Right Angle, Rear), actuator type (Round, Plunger), termination style (PC Pin), and panel cutout dimensions (Circular - 6.35mm Dia) are identical. The substitute part functions as a drop-in replacement.

Q: Why is the TPF11CGRA0 listed as Obsolete?

A: The TPF11CGRA0 carries Obsolete product status, indicating it has been discontinued by the manufacturer. The 1825100-4 is the active equivalent part that provides continued availability for applications requiring this switch specification.

Q: Are there any differences in compliance or certifications between the two parts?

A: The 1825100-4 provides enhanced compliance compared to the TPF11CGRA0. The substitute part is ROHS3 Compliant and rated MSL 1 (Unlimited), whereas the original part specifications did not include these certifications. This represents an improvement in regulatory alignment and moisture handling capability.

Q: What is the difference in packaging between these parts?

A: The TPF11CGRA0 packaging specification was not provided in the original documentation. The 1825100-4 is supplied in Bulk packaging, which is standard for production and maintenance applications requiring multiple units.

Q: Are the electrical and mechanical specifications identical?

A: Yes. Both parts share identical electrical specifications (0.4VA at 20V AC/DC, SPST-NO circuit, Off-Momentary function), mechanical specifications (Panel Mount Right Angle Rear, Round Plunger actuator, PC Pin termination, 6.35mm circular cutout), and environmental specifications (Operating temperature -30°C to 65°C, 100,000 cycle electrical life).

Q: Can I use 1825100-4 in new designs?

A: Yes. The 1825100-4 is an Active product with current manufacturer support, making it suitable for both replacement applications and new design implementations. The Active status ensures ongoing availability and supply chain reliability.
