TP33P003000 Pushbutton Switch SPST-NO Equivalent & Substitute Parts

Part Overview

The TP33P003000 is an APEM Inc. pushbutton switch with SPST-NO (Single Pole Single Throw - Normally Open) circuit configuration, rated for 0.4VA at 20V AC/DC. This through-hole mounted component features a round plunger actuator with power symbol marking and sealed construction. The part is Active status and ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when supply chain optimization is required, or when design flexibility allows for functionally compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TP33P003000 is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST-NO
• Current rating: 0.4VA (AC/DC)
• Voltage ratings: 20V AC and 20V DC
• Mounting type: Through Hole
• Actuator type: Round, Plunger
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C
• Switch function: Off-Mom (Momentary)

All four substitute parts listed meet these core electrical and mechanical requirements. Variations in electrical life cycles, ingress protection ratings, and sealing features do not preclude substitution when these parameters are not critical to the application.

Parameter Comparison

Engineering Selection Recommendations

All five parts listed are Active status components with ROHS3 compliance, confirming current manufacturing availability and environmental regulatory adherence.

TP11SH9CBE (C&K) and TP33P003000 (APEM) are functionally identical across all specified parameters, including 60,000 cycle electrical life. TP11SH9CBE carries REACH Affected status, whereas TP33P003000 is REACH Unaffected.

EP11SD1CBE (C&K) provides enhanced ingress protection at IP57 rating with epoxy sealed terminals, maintaining 60,000 cycle electrical life. MSL classification differs (Not Applicable vs. MSL 1).

800SP9B6M2RE and 800AWSP9M2RE (E-Switch) both deliver the required electrical specifications with 50,000 cycle electrical life. 800AWSP9M2RE includes IP67 ingress protection with epoxy sealed terminals, representing the highest environmental sealing specification among all alternatives.

Selection between these parts depends on application requirements for environmental protection and cycle life expectations. All parts satisfy the core electrical and mechanical requirements of the TP33P003000.

Frequently Asked Questions (FAQ)

Q: Can TP11SH9CBE directly replace TP33P003000 in existing designs?

A: Yes. Both parts share identical electrical ratings (0.4VA, 20V AC/DC), circuit configuration (SPST-NO), mounting type (Through Hole), actuator geometry (Round Plunger), and termination style (PC Pin). Operating temperature range and switch function are equivalent. The primary difference is REACH regulatory status.

Q: What is the difference between the E-Switch 800 series alternatives?

A: 800SP9B6M2RE and 800AWSP9M2RE both meet core electrical specifications. 800AWSP9M2RE provides IP67 ingress protection with epoxy sealed terminals, compared to 800SP9B6M2RE which has no specified ingress protection. Both deliver 50,000 electrical cycles versus 60,000 cycles in the primary part.

Q: Does the C&K EP11SD1CBE offer advantages over the APEM TP33P003000?

A: EP11SD1CBE maintains equivalent electrical performance (0.4VA, 20V, 60,000 cycles) and adds IP57 ingress protection with epoxy sealed terminals. This makes it suitable for applications requiring enhanced environmental sealing. MSL classification differs (Not Applicable vs. MSL 1 Unlimited).

Q: Are all substitute parts available in the same packaging?

A: All parts are supplied in Bulk packaging. Inventory levels vary: TP33P003000 (980 pcs), TP11SH9CBE (1,324 pcs), EP11SD1CBE (3,576 pcs), 800SP9B6M2RE (2,341 pcs), and 800AWSP9M2RE (1,115 pcs).

Q: Which substitute part has the longest electrical life?

A: TP33P003000, TP11SH9CBE, and EP11SD1CBE all specify 60,000 electrical cycles. The E-Switch alternatives (800SP9B6M2RE and 800AWSP9M2RE) specify 50,000 cycles.

Q: Can I use 800AWSP9M2RE in applications requiring sealed terminals?

A: Yes. 800AWSP9M2RE features epoxy sealed terminals and IP67 ingress protection (Dust Tight, Waterproof), making it suitable for sealed applications. This exceeds the environmental protection of the primary TP33P003000 part.
