TP32W003050 Pushbutton Switch SPDT Equivalent & Substitute Parts

Part Overview

The TP32W003050 is an APEM Inc. pushbutton switch featuring SPDT (Single Pole Double Throw) circuit configuration with 0.4VA current rating at 20V AC/DC. This through-hole, right-angle mounted switch operates in On-Momentary function with a sealed design and black round plunger actuator. The part is Active status and ROHS3 compliant, making it suitable for industrial control and consumer electronics applications where sealed pushbutton switching is required.

Equivalent and substitute parts become necessary when the primary part experiences supply constraints, extended lead times, or when design flexibility allows for alternative manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TP32W003050 is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: Must be SPDT
• Current Rating: Must be 0.4VA (AC/DC)
• Voltage Rating: Must support 20V AC and 20V DC minimum
• Mounting Type: Must be Through Hole, Right Angle
• Switch Function: Must be On-Momentary
• Actuator Type: Must be Round Plunger
• Termination Style: Must be PC Pin

The substitute parts identified below meet all mandatory electrical and mechanical parameters. Variations in electrical life cycles, operating temperature ranges, sealing features, and compliance certifications are noted but do not disqualify substitution when the core parameters align.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - 1-1825097-4 (TE Connectivity ALCOSWITCH)

The 1-1825097-4 meets all mandatory electrical and mechanical parameters. This part offers extended electrical life (100,000 cycles versus 60,000 cycles) and maintains PC Pin termination for direct PCB integration. The operating temperature range is reduced to -30°C to 65°C, which may limit use in high-temperature applications. RoHS status is not applicable for this manufacturer designation. This part is suitable for applications where the reduced temperature ceiling does not conflict with system requirements.

Functional Equivalent - EP12SD1ABE (C&K)

The EP12SD1ABE from C&K meets all core electrical and mechanical specifications. This part provides IP57 ingress protection (dust protected, waterproof) with epoxy sealed terminals, offering enhanced environmental sealing compared to the base TP32W003050. Electrical life is reduced to 30,000 cycles. ROHS3 compliance and REACH unaffected status align with the primary part. This substitute is appropriate for applications requiring superior environmental protection.

Functional Equivalent - TP12SH9ABE (C&K)

The TP12SH9ABE maintains identical electrical ratings, mounting configuration, and operating temperature range (-30°C to 85°C) as the TP32W003050. Electrical life is reduced to 30,000 cycles. ROHS3 compliance is maintained. REACH status is listed as affected, indicating potential regulatory considerations in specific markets. This part provides direct functional compatibility with temperature performance matching the original specification.

Frequently Asked Questions (FAQ)

Q: Can I use 1-1825097-4 in applications requiring operation above 65°C?

A: No. The 1-1825097-4 has a maximum operating temperature of 65°C, while the TP32W003050 operates to 85°C. Applications requiring sustained operation above 65°C must use EP12SD1ABE or TP12SH9ABE.

Q: What is the difference between the C&K EP12SD1ABE and TP12SH9ABE substitutes?

A: Both parts meet identical electrical and mechanical specifications. The EP12SD1ABE provides IP57 ingress protection with epoxy sealed terminals, suitable for harsh environments. The TP12SH9ABE offers standard sealing. Selection depends on environmental exposure requirements.

Q: Does the reduced electrical life of C&K substitutes affect reliability?

A: Electrical life ratings indicate cycle endurance under specified conditions. The TP32W003050 (60,000 cycles), EP12SD1ABE (30,000 cycles), and TP12SH9ABE (30,000 cycles) are all rated for their respective cycle counts. Application cycle requirements must be evaluated against these specifications.

Q: Are all substitutes ROHS3 compliant?

A: The TP32W003050, EP12SD1ABE, and TP12SH9ABE are ROHS3 compliant. The 1-1825097-4 has RoHS status listed as not applicable. Compliance requirements for your application must be verified against your specific regulatory obligations.

Q: Can these parts be used interchangeably on the same PCB?

A: Yes. All substitute parts use identical PC Pin termination and Through Hole, Right Angle mounting. Direct PCB substitution is mechanically and electrically compatible without layout modification.

Q: What is the REACH status difference between substitutes?

A: The TP32W003050 and EP12SD1ABE are REACH unaffected. The TP12SH9ABE is REACH affected, and the 1-1825097-4 is vendor undefined. Applications subject to REACH regulations must confirm compliance status with the specific manufacturer or distributor.
