Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TP11LT9V3LE is determined by the following critical parameters:

• Circuit configuration (SPST-NO)
• Current rating (1A AC/DC)
• Voltage ratings (120V AC, 28V DC)
• Mounting type (Through Hole)
• Actuator type and color (Round plunger, Black)
• Termination style (PC Pin)
• Operating temperature range (-30°C to 85°C)
• Electrical life rating (60,000 Cycles)

The TP11LT9V3RE qualifies as a direct substitute based on matching all critical electrical and mechanical parameters within the TP series family.

Parameter Comparison

Engineering Selection Recommendations

The TP11LT9V3RE is a direct functional equivalent to the obsolete TP11LT9V3LE. Both components share identical electrical ratings, mechanical specifications, and operating characteristics within the TP series. The TP11LT9V3RE maintains active product status, ensuring continued availability and supply chain reliability. Both parts meet RoHS compliance requirements and carry MSL 1 moisture sensitivity ratings. The primary distinction is REACH status classification; however, this does not affect electrical or mechanical compatibility. Selection of the TP11LT9V3RE is appropriate for replacement applications and new designs requiring SPST-NO pushbutton switch functionality at the specified voltage and current ratings.

Frequently Asked Questions (FAQ)

Q: Can the TP11LT9V3RE directly replace the TP11LT9V3LE in existing designs?

A: Yes. Both components share identical circuit configuration (SPST-NO), current rating (1A AC/DC), voltage ratings (120V AC, 28V DC), mounting type (Through Hole), actuator specifications (Round plunger, Black), and termination style (PC Pin). No design modifications are required.

Q: What is the significance of the product status difference (Obsolete vs. Active)?

A: The TP11LT9V3LE is obsolete and no longer manufactured. The TP11LT9V3RE is actively produced, ensuring reliable supply availability for both replacement and new production applications.

Q: Are there compliance differences between these parts?

A: Both parts are RoHS compliant and carry MSL 1 ratings. The TP11LT9V3RE is REACH Affected while the TP11LT9V3LE is REACH Unaffected. This classification difference does not impact electrical performance or mechanical compatibility.

Q: Do these parts have identical mechanical life specifications?

A: Mechanical life data is not provided for either component. Both parts are rated for 60,000 electrical cycles under the specified operating conditions.

Q: Are the through-hole mounting dimensions identical?

A: Both components use PC pin termination and through-hole mounting. Panel cutout dimensions are not specified in the available data. Verify physical dimensions against your PCB design requirements.
