Key Parameters

Substitute Part Grouping Explanation

Substitution of the TE Connectivity 1825099-3 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit type must be SPST-NO
• Current rating must be 0.4VA (AC/DC)
• Voltage ratings must be 20V AC and 20V DC minimum

Mechanical Compatibility Requirements:

• Mounting configuration must be through-hole, right-angle
• Termination must be PC pin
• Actuator type must be round plunger
• Switch function must be Off-Mom (momentary operation)

Environmental & Compliance Requirements:

• Operating temperature range must encompass or exceed -30°C to 65°C
• RoHS compliance status must be current (RoHS Compliant or ROHS3 Compliant)
• Moisture sensitivity level must be 1 (Unlimited)

The C&K TP11SH9ABE meets all electrical and mechanical requirements for direct substitution. Differences in electrical life (60,000 vs. 100,000 cycles) and operating temperature upper limit (85°C vs. 65°C) represent enhanced performance characteristics that do not preclude substitution.

Parameter Comparison

Engineering Selection Recommendations

The C&K TP11SH9ABE is a direct electrical and mechanical equivalent to the TE Connectivity 1825099-3 for applications requiring SPST-NO pushbutton switch functionality at 0.4VA, 20V ratings with through-hole right-angle mounting and PC pin termination.

Substitution Basis:

The TP11SH9ABE maintains full compatibility across all critical electrical parameters (circuit type, current rating, voltage ratings) and mechanical parameters (mounting configuration, termination style, actuator geometry). Both components are RoHS compliant and carry unlimited moisture sensitivity rating (MSL 1).

Availability Advantage:

The TE Connectivity 1825099-3 is discontinued at DiGi Electronics, whereas the C&K TP11SH9ABE maintains active product status with 12,057 units in stock, ensuring supply chain continuity for new designs and production requirements.

Performance Considerations:

The C&K substitute provides an extended operating temperature range (-30°C to 85°C versus -30°C to 65°C), offering enhanced thermal performance. The electrical life rating of 60,000 cycles on the substitute is lower than the original 100,000 cycles; this difference is application-dependent and should be evaluated against specific duty cycle requirements.

Compliance Status:

Both components meet current RoHS requirements. The C&K part carries ROHS3 compliance designation and REACH Affected status, indicating current regulatory alignment for European and international markets.

Frequently Asked Questions (FAQ)

Q: Can the C&K TP11SH9ABE be used as a direct replacement for the TE Connectivity 1825099-3 in existing PCB designs?

A: Yes. Both components share identical electrical ratings (0.4VA, 20V AC/DC, SPST-NO), mechanical mounting (through-hole right-angle), termination style (PC pin), and actuator configuration (round plunger). No PCB layout modifications are required for substitution.

Q: What is the difference in electrical life between these two parts?

A: The TE Connectivity 1825099-3 is rated for 100,000 electrical cycles, while the C&K TP11SH9ABE is rated for 60,000 cycles. Selection between these parts should be based on the application's expected cycle count over the component's service life.

Q: Does the C&K substitute operate across the same temperature range?

A: The C&K TP11SH9ABE operates from -30°C to 85°C, which exceeds the original part's range of -30°C to 65°C. For applications operating within the original -30°C to 65°C specification, the substitute provides additional thermal margin.

Q: Are both parts RoHS compliant?

A: Yes. The TE Connectivity 1825099-3 is RoHS Compliant, and the C&K TP11SH9ABE is ROHS3 Compliant. Both meet current RoHS requirements for lead-free construction and restricted substance compliance.

Q: What is the packaging difference between these parts?

A: The TE Connectivity 1825099-3 is supplied in standard packaging, while the C&K TP11SH9ABE is supplied in bulk packaging. Bulk packaging does not affect component functionality or electrical characteristics.

Q: Why is the TE Connectivity part discontinued?

A: The TE Connectivity 1825099-3 is discontinued at DiGi Electronics. The C&K TP11SH9ABE remains in active production with current inventory availability, making it the recommended choice for ongoing supply requirements.

Q: Are there any mechanical dimension differences between these switches?

A: Both components feature identical mounting configurations (through-hole, right-angle) and termination styles (PC pin). No mechanical dimension data was provided in the specifications; physical verification is recommended if panel cutout dimensions or mounting hole spacing are critical to the application.

Q: Does the C&K part include any additional features?

A: The C&K TP11SH9ABE is specified as sealed, providing enhanced protection against environmental contamination compared to the standard TE Connectivity part. This represents an enhancement for applications requiring ingress protection.
