Key Parameters

Substitute Part Grouping Explanation

Substitution of the TT11DGPC1 toggle switch is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Current rating must be 0.4VA (AC/DC)
• Voltage ratings must be 20V AC and 20V DC minimum

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Termination style must be PC Pin
• Actuator type must be Standard Round
• Actuator length must be 5.61mm
• Operating temperature range must encompass -30°C to 85°C
• Electrical life must be 80,000 cycles minimum

The substitute part 1825219-3 meets all electrical and mechanical parameters specified for the TT11DGPC1, establishing direct functional equivalence within the TT series toggle switch family.

Parameter Comparison

Engineering Selection Recommendations

The TT11DGPC1 and 1825219-3 are electrically and mechanically equivalent toggle switches within the TE Connectivity ALCOSWITCH TT series. Both components satisfy identical functional requirements for SPDT On-On switching applications at 0.4VA and 20V ratings.

Compliance Consideration: The primary distinction between these parts is regulatory compliance status. The 1825219-3 is ROHS3 compliant, while the TT11DGPC1 is RoHS non-compliant. Applications subject to RoHS directives or customer specifications requiring RoHS compliance must utilize the 1825219-3 substitute part.

Moisture Sensitivity: The 1825219-3 carries a Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage and handling. The TT11DGPC1 lists MSL as Not Applicable.

Both parts are active products with established inventory availability. Selection between these equivalent parts should be based on regulatory requirements and compliance mandates applicable to the end application.

Frequently Asked Questions (FAQ)

Q: Are TT11DGPC1 and 1825219-3 electrically interchangeable?
