Substitute Part Grouping Explanation

Substitution of the obsolete 1-1825098-7 is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Circuit configuration: SPST-NO
• Switch function: Off-Mom (momentary operation)
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC

Mechanical Equivalence Criteria:

• Mounting type: Panel Mount, Rear
• Termination style: PC Pin
• Actuator type: Round, Plunger
• Operating temperature range: -30°C to 65°C
• Electrical life: 100,000 cycles

Compliance Criteria:

• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

The substitute part 1825100-1 maintains full electrical equivalence and mechanical compatibility across all specified parameters. Variations in panel cutout dimensions and product status (active versus obsolete) do not affect functional substitution capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: TE Connectivity ALCOSWITCH 1825100-1

The 1825100-1 is the manufacturer-recommended substitute for the obsolete 1-1825098-7. This part maintains complete electrical and functional equivalence across all critical parameters including circuit configuration, voltage and current ratings, operating temperature range, and electrical life specifications.

Compliance Advantages: The 1825100-1 carries active product status with ROHS3 compliance certification, providing enhanced regulatory alignment compared to the obsolete RoHS Compliant status of the original part. Both components maintain MSL 1 (Unlimited) moisture sensitivity classification.

Mechanical Consideration: The panel cutout dimension increases from 4.83mm to 6.35mm diameter. This difference requires panel modification during implementation. The actuator design remains functionally equivalent with round plunger configuration suitable for momentary operation in the same application context.

Supply Chain Status: The 1825100-1 is currently in active production with documented inventory availability, ensuring reliable sourcing for new designs and field service applications.

Frequently Asked Questions (FAQ)

Q: Can the 1825100-1 directly replace the 1-1825098-7 without circuit modification?

A: Yes. Both parts are electrically identical with SPST-NO circuit configuration, 0.4VA current rating, and 20V voltage rating. No circuit redesign is required. Panel cutout dimensions differ and require mechanical modification to the mounting surface.

Q: What is the significance of the panel cutout dimension change from 4.83mm to 6.35mm?

A: The larger cutout diameter of the 1825100-1 accommodates the switch body. Existing panel designs with 4.83mm cutouts require enlargement to 6.35mm for proper fit. This is a mechanical consideration only and does not affect electrical performance.

Q: Are the actuator designs functionally equivalent?

A: Yes. Both parts feature round plunger actuators with momentary (Off-Mom) switch function. The 1-1825098-7 specifies "Flush" design while the 1825100-1 specifies standard plunger design. Both are suitable for panel-mounted pushbutton applications with identical electrical characteristics.

Q: Why is the 1-1825098-7 classified as obsolete?

A: The part has reached end-of-life status in the manufacturer's product portfolio. The 1825100-1 represents the active equivalent in the TP series, ensuring continued availability and support for new production.

Q: Does the ROHS3 compliance of the 1825100-1 provide additional environmental benefits?

A: ROHS3 represents an updated compliance certification reflecting current regulatory standards. Both parts are RoHS compliant. The 1825100-1 carries the more current ROHS3 designation, aligning with contemporary procurement requirements.

Q: Are there packaging differences between these parts?

A: The 1-1825098-7 is listed with unspecified packaging, while the 1825100-1 is supplied in Bulk packaging. Packaging format does not affect component functionality or electrical performance.

Q: What is the electrical life specification for both parts?

A: Both the 1-1825098-7 and 1825100-1 are rated for 100,000 cycles of electrical operation, providing equivalent reliability and service life in momentary switch applications.

Q: Can the 1825100-1 operate across the same temperature range as the original part?

A: Yes. Both parts operate across the identical temperature range of -30°C to 65°C, ensuring equivalent thermal performance in the specified application environment.
