Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TL49P080400 are qualified based on the following critical parameters that must match or exceed the main part specifications:

Mandatory Matching Parameters:

• Circuit Configuration: DPDT
• Switch Function: On-Off-On
• Current Rating: 0.4VA (AC/DC) minimum
• Voltage Rating - AC: 20V minimum
• Voltage Rating - DC: 20V minimum
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Operating Temperature Range: -30°C to 85°C minimum
• RoHS Status: ROHS3 Compliant

Allowable Variations:

• Actuator Length: Variations permitted within mechanical design constraints
• Actuator Material: Brass with different plating options (Nickel or Chrome)
• Electrical Life: Equal or greater cycle rating
• Packaging: Bulk or Tray formats
• Manufacturer: Different qualified manufacturers

The substitute parts listed below meet all mandatory parameters and are therefore electrically and mechanically interchangeable with the TL49P080400 in standard applications.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are qualified alternatives to the TL49P080400 based on compliance and product status criteria:

200MDP3T2B2M2RE (E-Switch): This part provides electrical equivalence with identical voltage and current ratings. The reduced actuator length (5.33mm versus 7.40mm) represents a mechanical variation that may affect panel mounting depth requirements. Chrome plating on the actuator offers alternative corrosion resistance characteristics compared to nickel plating. ROHS3 compliance and active product status confirm ongoing manufacturer support.

B23JP (NKK Switches): This part exceeds the voltage specification (28V versus 20V) and provides enhanced electrical life (50,000 cycles versus 30,000 cycles), making it suitable for applications requiring higher reliability margins. The actuator length (6.30mm) falls between the main part and the E-Switch alternative. Nickel plating matches the main part material specification. ROHS3 compliance and active product status confirm ongoing manufacturer support. Tray packaging differs from bulk packaging of the main part.

All three parts maintain identical circuit configuration, switch function, current rating, mounting type, termination style, and operating temperature range, confirming electrical and mechanical interchangeability within the specified parameter envelope.

Frequently Asked Questions (FAQ)

Q: Can the 200MDP3T2B2M2RE be used as a direct replacement for the TL49P080400?

A: Yes. Both parts share identical electrical specifications (DPDT, On-Off-On, 0.4VA, 20V AC/DC) and mounting characteristics (through-hole, PC pin termination). The actuator length difference (5.33mm versus 7.40mm) requires verification of panel cutout and mechanical clearance in your specific application.

Q: What is the difference between the B23JP and the TL49P080400?

A: The B23JP provides higher voltage rating (28V versus 20V) and extended electrical life (50,000 cycles versus 30,000 cycles). Both maintain identical circuit configuration, current rating, and operating temperature range. Actuator length (6.30mm) and packaging format (tray versus bulk) differ from the main part.

Q: Are all three parts RoHS compliant?

A: Yes. The TL49P080400, 200MDP3T2B2M2RE, and B23JP are all ROHS3 compliant, confirming restricted substance compliance for regulated applications.

Q: Does actuator length affect electrical performance?

A: No. Actuator length variations (5.33mm, 6.30mm, 7.40mm) are mechanical design parameters that do not affect electrical switching performance. Panel mounting depth and operator ergonomics may be influenced by these differences.

Q: Can I use the B23JP in a 20V application?

A: Yes. The B23JP is rated for 28V AC/DC, which exceeds the 20V requirement. Components rated for higher voltages are suitable for lower voltage applications within their current rating specifications.

Q: What is the significance of electrical life ratings?

A: Electrical life indicates the number of switching cycles a component is rated to perform reliably. The TL49P080400 and 200MDP3T2B2M2RE are rated for 30,000 cycles, while the B23JP is rated for 50,000 cycles. Higher cycle ratings provide extended service life in high-frequency switching applications.

Q: How does packaging format affect component selection?

A: Packaging format (bulk versus tray) affects handling, storage, and assembly processes but does not influence electrical or mechanical performance. Selection depends on your procurement and manufacturing workflow requirements.
