Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1-1825098-1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary contact)
• Current rating: 1A (AC/DC)
• Mounting type: Panel Mount, Rear
• Actuator type: Round, Plunger
• Termination style: PC Pin
• Electrical life: 60,000 Cycles

Allowable Variation Parameters:

• Voltage rating (AC): Minimum 125V required
• Voltage rating (DC): Minimum 20V required
• Panel cutout diameter: Within mechanical tolerance for rear panel mounting
• Operating temperature range: Must encompass or exceed -30°C to 65°C
• Product status: Active status preferred for ongoing availability

The substitute part TP11SHCQE manufactured by C&K meets all mandatory matching parameters and exceeds minimum voltage and temperature requirements, qualifying it as a direct functional equivalent.

Engineering Selection Recommendations

The TP11SHCQE from C&K is a qualified substitute for the obsolete 1-1825098-1. Selection rationale is based on the following factors:

Functional Equivalence: The TP11SHCQE maintains identical circuit configuration (SPST-NO), switch function (momentary), current rating (1A AC/DC), mounting configuration (rear panel mount), and termination style (PC pin). Electrical life specification matches at 60,000 cycles.

Voltage Compatibility: The TP11SHCQE is rated for 120V AC and 28V DC, meeting or exceeding the original part's 125V AC and 20V DC requirements. The 5V AC differential is within acceptable tolerance for standard AC line voltage applications.

Mechanical Compatibility: Panel cutout dimensions differ by 0.12mm (4.95mm versus 4.83mm), representing a negligible variance within standard mechanical tolerances for rear panel mounting applications.

Environmental Performance: The TP11SHCQE operating temperature range of -30°C to 85°C exceeds the original specification of -30°C to 65°C, providing enhanced thermal margin.

Regulatory Compliance: The TP11SHCQE is ROHS3 compliant and REACH affected, meeting current environmental and regulatory standards. The original part's compliance status is not specified.

Product Availability: The TP11SHCQE is actively manufactured with confirmed inventory availability, whereas the 1-1825098-1 is obsolete.

Frequently Asked Questions (FAQ)

Q: Can the TP11SHCQE directly replace the 1-1825098-1 in existing applications?

A: Yes. The TP11SHCQE meets all mandatory electrical and mechanical parameters. The 120V AC rating is acceptable for 125V AC applications, and the 28V DC rating exceeds the 20V DC requirement. Panel cutout dimensions are compatible within standard mechanical tolerances.

Q: What is the significance of the panel cutout dimension difference (4.83mm versus 4.95mm)?

A: The 0.12mm difference is within standard mechanical tolerance for rear panel mount switches. Existing panel cutouts designed for the 1-1825098-1 will accommodate the TP11SHCQE without modification.

Q: Does the TP11SHCQE sealed feature affect compatibility?

A: The sealed feature of the TP11SHCQE provides enhanced environmental protection and does not negatively impact compatibility. This is an improvement over the original part specification.

Q: Are there compliance differences between the two parts?

A: The TP11SHCQE is ROHS3 compliant and REACH affected, meeting current regulatory requirements. The original 1-1825098-1 compliance status is not specified. For new designs or applications subject to environmental regulations, the TP11SHCQE is the appropriate selection.

Q: What is the inventory status for the substitute part?

A: The TP11SHCQE is actively manufactured by C&K with 1,802 pieces confirmed in stock as new original inventory.

Q: Are there any electrical performance differences in the 60,000 cycle electrical life specification?

A: Both parts specify identical electrical life of 60,000 cycles, indicating equivalent mechanical durability and contact reliability.
