TPD11CGRA0 Equivalent & Substitute Parts

Part Overview

The TPD11CGRA0 is a pushbutton switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a Standard SPST-NO (Single Pole Single Throw - Normally Open) through-hole, right-angle mounted component. The switch is rated for 0.4VA at 20V AC/DC with an off-momentary switch function and round plunger actuator. The TPD11CGRA0 is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design support and procurement requirements.

Substitute Part Grouping Explanation

Substitute parts for the TPD11CGRA0 are identified based on electrical and mechanical parameter equivalence within the TPD11 series and related TE Connectivity ALCOSWITCH product lines. Substitution eligibility is determined by matching the following critical parameters:

• Circuit configuration: SPST-NO
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Through Hole, Right Angle
• Switch function: Off-Mom
• Actuator type: Round, Plunger
• Termination style: PC Pin
• Operating temperature range: -30°C ~ 65°C
• Electrical life: 100,000 Cycles

Parts meeting these criteria are electrically and mechanically interchangeable with the TPD11CGRA0 in circuit applications. Variations in actuator color, product status, and packaging do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

TPD11CGRA2 is the manufacturer-recommended substitute for the obsolete TPD11CGRA0. Both parts share identical electrical specifications, mechanical configuration, and operating parameters. The TPD11CGRA2 maintains active product status with TE Connectivity ALCOSWITCH Switches, ensuring continued availability and supply chain support. The only functional difference is the red actuator color versus the black actuator of the TPD11CGRA0. Both parts carry RoHS non-compliant status.

1825099-3 is an alternative substitute that provides electrical and mechanical equivalence to the TPD11CGRA0. This part is classified as discontinued at DiGi Electronics but maintains RoHS Compliant certification, offering an advantage for applications requiring RoHS compliance. The 1825099-3 uses a different base product numbering scheme (1825099 versus TPD11) but delivers identical switch performance and circuit behavior.

For new designs and ongoing procurement, TPD11CGRA2 is the primary selection due to active product status. For applications requiring RoHS compliance, 1825099-3 provides functional equivalence with regulatory advantage, subject to supply availability verification.

Frequently Asked Questions (FAQ)

Q: Can TPD11CGRA2 be used as a direct replacement for TPD11CGRA0 in existing circuit designs?

A: Yes. The TPD11CGRA2 is electrically and mechanically equivalent to the TPD11CGRA0. Both parts share identical circuit configuration (SPST-NO), current rating (0.4VA AC/DC), voltage rating (20V AC/DC), mounting type (through-hole right-angle), switch function (off-momentary), actuator type (round plunger), termination style (PC pin), operating temperature range (-30°C to 65°C), and electrical life (100,000 cycles). The red actuator color of the TPD11CGRA2 does not affect electrical performance or circuit compatibility.

Q: What is the difference between TPD11CGRA0 and 1825099-3?

A: Both parts are electrically and mechanically equivalent with identical switch specifications. The primary differences are: (1) base product numbering (TPD11 versus 1825099), (2) RoHS compliance status (1825099-3 is RoHS Compliant while TPD11CGRA0 is non-compliant), and (3) product status (1825099-3 is discontinued at DiGi Electronics while TPD11CGRA0 is obsolete). Functionally, both parts perform identically in circuit applications.

Q: Why is the TPD11CGRA0 classified as obsolete?

A: The TPD11CGRA0 has been discontinued by TE Connectivity ALCOSWITCH Switches and is no longer in active production. The TPD11CGRA2 serves as the active replacement within the TPD11 series, maintaining identical electrical and mechanical specifications.

Q: Does actuator color affect switch functionality?

A: No. Actuator color is a visual identification feature only and does not affect electrical performance, switching characteristics, or circuit behavior. The TPD11CGRA0 (black actuator) and TPD11CGRA2 (red actuator) function identically in all electrical and mechanical aspects.

Q: What packaging formats are available for substitute parts?

A: TPD11CGRA2 is supplied in Bulk packaging. The TPD11CGRA0 and 1825099-3 packaging specifications are not designated in the product data. Packaging format should be verified with the supplier for procurement requirements.

Q: Are there RoHS compliance considerations for substitute selection?

A: Yes. The TPD11CGRA0 and TPD11CGRA2 are both RoHS non-compliant. The 1825099-3 is RoHS Compliant. For applications requiring RoHS compliance, 1825099-3 is the appropriate selection. For applications without RoHS requirements, all three parts are functionally equivalent.

Q: What is the electrical life specification for these switches?

A: All three parts (TPD11CGRA0, TPD11CGRA2, and 1825099-3) are rated for 100,000 electrical cycles, indicating equivalent durability and operational lifespan in switching applications.
