Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 2-1825097-0 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Actuator type: Round plunger design
• Termination style: PC pin
• Series designation: TP
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variations:

• Mounting type: Through-hole to panel mount rear configurations are acceptable when the electrical circuit, actuator geometry, and termination remain consistent
• Actuator marking: Absence of marking in both original and substitute maintains consistency
• Product status transition: From obsolete to active status is permissible for functional equivalents

The substitute part 1825100-1 maintains all critical electrical and mechanical parameters while transitioning to an active product status with enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The substitute part 1825100-1 is the designated equivalent for the obsolete 2-1825097-0 based on the following engineering criteria:

Functional Equivalence: Both components share identical circuit configuration (SPST-NO), switch function (Off-Mom), actuator design (round plunger), and termination methodology (PC pin). These parameters define the core electrical and mechanical behavior required for circuit operation.

Compliance Status: The substitute part 1825100-1 carries active product status with ROHS3 compliance certification, whereas the original part is obsolete with not-applicable RoHS status. Selection of the active substitute ensures compliance with current regulatory requirements and guarantees ongoing manufacturer support and availability.

Electrical Specifications: The substitute part provides specified electrical ratings (0.4VA at 20V AC/DC) and operational life data (100,000 cycles), establishing quantified performance parameters absent from the original part documentation.

Regulatory Alignment: Both components share identical ECCN (EAR99) and HTSUS (8536.50.9031) classifications, confirming trade compliance consistency.

Mounting Consideration: The transition from through-hole to panel mount rear configuration requires mechanical integration review specific to the application circuit board layout and enclosure design.

Frequently Asked Questions (FAQ)

Q: Can the 1825100-1 directly replace the 2-1825097-0 in existing designs?

A: Electrical and functional compatibility is confirmed through matching SPST-NO circuit, Off-Mom switch function, round plunger actuator, and PC pin termination. Mechanical integration requires evaluation of the mounting type change from through-hole to panel mount rear configuration relative to the specific application's physical constraints.

Q: What are the key parameters that define substitution eligibility?

A: Substitution is determined by alignment of circuit configuration (SPST-NO), switch function (Off-Mom), actuator type (round plunger), termination style (PC pin), and series designation (TP). These parameters establish electrical operation and mechanical interface requirements.

Q: Why is the original part classified as obsolete?

A: The 2-1825097-0 carries obsolete product status, indicating discontinuation by the manufacturer. The active substitute 1825100-1 provides functional equivalence with current availability and regulatory compliance.

Q: Are there compliance differences between the original and substitute parts?

A: The original part lists RoHS status as not applicable. The substitute part 1825100-1 is ROHS3 compliant, aligning with current environmental and regulatory standards. Both components share identical ECCN and HTSUS classifications.

Q: What electrical specifications apply to the substitute part?

A: The 1825100-1 is rated for 0.4VA at 20V (both AC and DC), with an operating temperature range of -30°C to 65°C and electrical life of 100,000 cycles.

Q: Does the mounting type change affect circuit functionality?

A: The transition from through-hole to panel mount rear does not alter electrical circuit behavior or switch function. Physical integration into the application's mechanical assembly requires design-specific evaluation.

Q: What is the moisture sensitivity classification for both parts?

A: Both the original 2-1825097-0 and substitute 1825100-1 carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
