TP12LTCQE Equivalent & Substitute Parts

Part Overview

The TP12LTCQE is an active SPDT pushbutton switch manufactured by C&K, designed for panel mount rear installation with a sealed design. This component operates at 1A (AC/DC) with voltage ratings of 120V AC and 28V DC, featuring a round plunger actuator with PC pin termination. The switch is specified for 30,000 electrical cycles and operates across a temperature range of -30°C to 85°C. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when inventory requirements necessitate component alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TP12LTCQE is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit Configuration: SPDT
• Switch Function: On-Mom
• Mounting Type: Panel Mount, Rear
• Actuator Type: Round, Plunger
• Termination Style: PC Pin
• Panel Cutout Dimensions: Circular - 6.35mm Dia

Allowable Parameter Variations:

• Current Rating: Substitute must meet or exceed the application requirement (minimum 1A AC/DC)
• Voltage Rating - AC: Substitute must meet or exceed 120V AC
• Voltage Rating - DC: Substitute must meet or exceed 28V DC
• Operating Temperature Range: Substitute must encompass or exceed -30°C to 85°C
• Electrical Life: Substitute must meet or exceed 30,000 cycles
• RoHS and Moisture Sensitivity compliance must be maintained

The substitute part 1825100-7 shares the core mechanical and electrical architecture (SPDT, On-Mom, Panel Mount Rear, Round Plunger, PC Pin, 6.35mm circular cutout) but operates at reduced current and voltage ratings. This part is suitable only for applications where the lower electrical specifications are acceptable.

Engineering Selection Recommendations

TP12LTCQE Selection Criteria: Use the TP12LTCQE when applications require 1A current capacity at 120V AC or 28V DC, with operating temperatures up to 85°C. This part is ROHS3 compliant and maintains unlimited moisture sensitivity rating, suitable for standard industrial panel mount applications.

1825100-7 Selection Criteria: The 1825100-7 substitute is applicable only in applications where current requirements do not exceed 0.4VA and voltage requirements do not exceed 20V AC/DC. The operating temperature range limitation to 65°C maximum must be evaluated against application requirements. This substitute offers extended electrical life (100,000 cycles) and maintains ROHS3 compliance. The substitute is not suitable for direct replacement in applications designed for the full electrical specifications of the TP12LTCQE.

Both parts maintain active product status and equivalent compliance certifications (ROHS3, EAR99 ECCN classification, HTSUS 8536.50.9031).

Frequently Asked Questions (FAQ)

Q: Can the 1825100-7 be used as a direct replacement for the TP12LTCQE?

A: No. While both parts share identical mechanical interfaces (6.35mm circular panel cutout, rear panel mount, round plunger actuator, PC pin termination), the 1825100-7 has reduced electrical ratings. Direct substitution is only valid if the application operates at 0.4VA maximum current and 20V maximum voltage. Applications designed for 1A at 120V AC or 28V DC cannot use this substitute.

Q: What are the key compatibility factors for SPDT pushbutton switch substitution?

A: Mechanical compatibility requires matching panel cutout dimensions, mounting orientation, actuator type, and termination style. Electrical compatibility requires the substitute to meet or exceed the application's current and voltage requirements. Both the TP12LTCQE and 1825100-7 maintain identical mechanical specifications but differ in electrical ratings.

Q: How do operating temperature ranges affect substitution decisions?

A: The TP12LTCQE operates from -30°C to 85°C, while the 1825100-7 operates from -30°C to 65°C. Applications requiring operation above 65°C cannot use the 1825100-7 substitute. The narrower temperature range of the substitute must be evaluated against the specific application environment.

Q: Are there packaging differences between these parts?

A: Yes. The TP12LTCQE is supplied in Tray packaging, while the 1825100-7 is supplied in Bulk packaging. Packaging format may affect handling, storage, and integration into assembly processes but does not affect electrical or mechanical compatibility.

Q: Do both parts meet the same compliance standards?

A: Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and EAR99 ECCN classification. Compliance equivalence is maintained between the main part and substitute.
