Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TP33WW03050 are qualified based on the following critical parameters that determine functional equivalence:

• Circuit configuration: SPST-NO
• Current rating: 0.4VA (AC/DC)
• Voltage rating: 20V AC and 20V DC
• Mounting type: Through hole, right angle, vertical orientation
• Actuator type: Round plunger
• Switch function: Off-Mom (momentary)
• Termination style: PC pin
• Operating temperature range: -30°C to 85°C
• Electrical life: 60,000 cycles

The identified substitute parts TP11SH9AVBE (C&K) and EP11SD1AVBE (C&K) meet all critical electrical and mechanical parameters. Variations in packaging format, ingress protection rating, and sealing features do not affect core switching functionality for standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Selection between the main part and substitutes should be based on:

• Packaging requirements: TP33WW03050 is supplied in bulk format, while TP11SH9AVBE and EP11SD1AVBE are supplied in tray format
• Environmental protection: EP11SD1AVBE provides IP57 ingress protection with epoxy sealed terminals, suitable for applications requiring enhanced moisture and dust resistance
• Feature set: TP33WW03050 includes overtravel feature; TP11SH9AVBE includes sealed design; EP11SD1AVBE includes epoxy sealed terminals
• REACH compliance: TP11SH9AVBE is REACH affected; TP33WW03050 and EP11SD1AVBE are REACH unaffected

Frequently Asked Questions (FAQ)

Q: Can TP11SH9AVBE or EP11SD1AVBE be used as direct replacements for TP33WW03050?

A: Yes. Both parts share identical electrical specifications (SPST-NO, 0.4VA, 20V AC/DC), mechanical configuration (through-hole right-angle vertical mounting, round plunger actuator), and operational characteristics (60,000 cycle electrical life, -30°C to 85°C operating range). Differences in packaging format and sealing features do not affect core switching functionality.

Q: What is the difference between the three parts?

A: The primary differences are packaging format (bulk vs. tray), ingress protection rating, and terminal sealing. TP33WW03050 features overtravel; TP11SH9AVBE is sealed; EP11SD1AVBE provides IP57 protection with epoxy sealed terminals. All three deliver identical electrical performance.

Q: Which part should be selected for outdoor or high-moisture applications?

A: EP11SD1AVBE is the appropriate choice for applications requiring environmental protection, as it provides IP57 ingress protection and epoxy sealed terminals.

Q: Are there any compliance differences between these parts?

A: All three parts are ROHS3 compliant. TP33WW03050 and EP11SD1AVBE are REACH unaffected; TP11SH9AVBE is REACH affected. Selection should account for end-use regulatory requirements.

Q: What is the inventory status of these parts?

A: TP33WW03050 has 858 pieces in stock; TP11SH9AVBE has 7,612 pieces in stock; EP11SD1AVBE has 1,163 pieces in stock.
