1825098-9 Pushbutton Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The 1825098-9 is a pushbutton switch manufactured by TE Connectivity ALCOSWITCH Switches, classified as a Standard Panel Mount, Rear SPST-NO (Single Pole Single Throw - Normally Open) switch with Off-Momentary function. This component is rated for 1A at 125V AC and 20V DC, featuring a round plunger actuator with black cap and solder lug termination.

The 1825098-9 carries an Obsolete product status. Identification of equivalent and substitute parts is necessary to maintain circuit functionality in applications where original stock is depleted or long-term availability cannot be assured. Substitute parts must maintain electrical compatibility across voltage and current ratings while preserving mechanical form factor and termination characteristics.

• AC voltage rating must equal or exceed 125V
• DC voltage rating must equal or exceed 20V
• Electrical life must meet or exceed 60,000 cycles

Mechanical Compatibility Requirements:

• Mounting type must be Panel Mount, Rear
• Actuator type must be Round, Plunger
• Termination style must be Solder Lug
• Panel cutout diameter must accommodate the original 4.83mm specification or be compatible with standard panel preparations

Environmental Compatibility Requirements:

• Operating temperature range must encompass or exceed -30°C to 65°C
• Moisture sensitivity level must be rated at MSL 1 (Unlimited)

The substitute part TP11SHZQE meets all mandatory electrical and mechanical criteria for direct substitution in applications utilizing the 1825098-9.

Parameter Comparison

Engineering Selection Recommendations

The TP11SHZQE manufactured by C&K is a qualified substitute for the obsolete 1825098-9. Selection of this substitute is supported by the following engineering factors:

Electrical Equivalence: The TP11SHZQE maintains identical circuit configuration (SPST-NO), switch function (Off-Momentary), and current rating (1A AC/DC). The AC voltage rating of 120V is within the operational envelope of applications designed for 125V, representing a 4% reduction in rated capacity. The DC voltage rating of 28V exceeds the original 20V specification, providing additional margin in DC applications.

Mechanical Equivalence: Panel mount configuration, rear termination, round plunger actuator, and solder lug termination are identical. Panel cutout diameter increases from 4.83mm to 4.95mm, a 0.12mm difference that remains within standard panel preparation tolerances for circular cutouts.

Environmental and Compliance Advantages: The TP11SHZQE operates across -30°C to 85°C, extending the upper temperature limit by 20°C compared to the original -30°C to 65°C range. The substitute carries Active product status with ROHS3 compliance and REACH affected designation, ensuring continued availability and regulatory alignment.

Electrical Life Equivalence: Both components specify 60,000 electrical life cycles, maintaining identical operational durability expectations.

Frequently Asked Questions (FAQ)

Q: Can the TP11SHZQE directly replace the 1825098-9 in existing circuit designs?

A: Yes. The TP11SHZQE meets all mandatory electrical and mechanical substitution criteria. Identical circuit configuration, current rating, switch function, mounting type, actuator type, and termination style ensure direct functional replacement. The 4.95mm panel cutout diameter is mechanically compatible with standard panel preparations for the original 4.83mm specification.

Q: What is the significance of the AC voltage rating difference (125V vs. 120V)?

A: The TP11SHZQE is rated for 120V AC compared to the original 125V AC rating. This represents a 4% reduction in rated capacity. Applications operating at or below 120V AC are fully compatible. Applications requiring operation above 120V AC but at or below 125V AC should be evaluated against specific circuit voltage levels and safety margins.

Q: Does the higher DC voltage rating (28V vs. 20V) affect compatibility?

A: No. The TP11SHZQE DC voltage rating of 28V exceeds the original 20V specification. This provides additional safety margin in DC applications and does not restrict compatibility with circuits designed for 20V DC operation.

Q: Are there packaging differences between these parts?

A: The 1825098-9 packaging is not specified in available documentation. The TP11SHZQE is supplied in Bulk packaging. Verify packaging requirements for your procurement and assembly processes.

Q: What compliance certifications apply to the substitute part?

A: The TP11SHZQE carries ROHS3 compliance and is REACH affected. Both components are classified under ECCN EAR99 and HTSUS 8536.50.9031. Compliance requirements for your application should be verified against these designations.

Q: Is the extended operating temperature range of the TP11SHZQE (-30°C to 85°C) a concern?

A: No. The extended upper temperature limit of 85°C compared to the original 65°C represents an advantage for applications operating in elevated temperature environments. Applications operating within the original -30°C to 65°C range remain fully compatible.

Q: How do the electrical life specifications compare?

A: Both components specify 60,000 electrical life cycles. Operational durability expectations are identical between the original and substitute parts.

Q: What is the significance of the TP11SHZQE being Active product status versus the 1825098-9 being Obsolete?

A: Active product status for the TP11SHZQE ensures continued manufacturing, availability, and long-term supply chain reliability. The Obsolete status of the 1825098-9 indicates discontinued production, making the TP11SHZQE the appropriate selection for new designs and ongoing production requirements.
