Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TL49P000000 are qualified based on the following critical parameters:

• Circuit Configuration: DPDT topology required for functional equivalence
• Switch Function: On-Off-On operation maintained across all substitutes
• Current Rating: 0.4VA (AC/DC) as baseline electrical capacity
• Voltage Rating: Minimum 20V AC/DC; higher ratings acceptable for backward compatibility
• Mounting Type: Through Hole configuration for PCB assembly compatibility
• Termination Style: PC Pin or equivalent pin-based termination for circuit board integration
• Operating Temperature: -30°C to 85°C range or broader specification acceptable
• RoHS Compliance: ROHS3 Compliant status maintained across all alternatives
• Product Status: Active classification ensures ongoing availability and support

The following parts meet these substitution criteria: E-Switch 200MDP3T2B2M2RE, NKK Switches B23HW, and NKK Switches B23JP.

Parameter Comparison

Engineering Selection Recommendations

E-Switch 200MDP3T2B2M2RE: This substitute provides the closest electrical and mechanical alignment to the TL49P000000. Voltage ratings, current capacity, and termination style (PC Pin) are identical. Actuator length variance (5.33mm vs. 5.30mm) is negligible for panel-mount applications. Both parts maintain ROHS3 compliance and Active product status. Electrical life specification is equivalent at 30,000 cycles. This part is recommended as the primary substitute when TL49P000000 inventory is constrained.

NKK Switches B23JP: This substitute maintains DPDT circuit configuration, On-Off-On function, and 0.4VA current rating. Voltage ratings are elevated to 28V AC/DC, providing enhanced electrical margin for applications operating below 20V. PC Pin termination matches the original specification. Standard Round actuator type aligns with the primary part. Electrical life is rated at 50,000 cycles, exceeding the original specification. ROHS3 compliance and Active product status are maintained. Tray packaging differs from Bulk; verify packaging requirements for procurement workflows.

NKK Switches B23HW: This substitute meets core electrical requirements with DPDT configuration and 0.4VA rating at 28V AC/DC. Wire Wrap termination differs from the original PC Pin specification; circuit board integration requires verification of compatibility with existing PCB pad design. Flatted actuator type introduces a mechanical variation from the Standard Round original. Electrical life is rated at 50,000 cycles. ROHS3 compliance and Active product status are confirmed. This part is suitable only when Wire Wrap termination is compatible with the target application.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 200MDP3T2B2M2RE be used as a direct replacement for the TL49P000000?

A: Yes. The 200MDP3T2B2M2RE matches the TL49P000000 in circuit configuration (DPDT), current rating (0.4VA AC/DC), voltage rating (20V AC/DC), mounting type (Through Hole), and termination style (PC Pin). Actuator length difference (5.33mm vs. 5.30mm) is within acceptable tolerance for panel-mount applications. Both parts are ROHS3 compliant and Active status.

Q: What is the key difference between the NKK Switches B23JP and B23HW?

A: The primary difference is termination style. B23JP uses PC Pin termination, matching the original TL49P000000 specification. B23HW uses Wire Wrap termination, requiring verification of PCB pad compatibility. Both parts share identical electrical ratings (0.4VA, 28V AC/DC), DPDT configuration, and 50,000-cycle electrical life. Actuator type also differs: B23JP is Standard Round (matching the original), while B23HW is Flatted.

Q: Are the NKK Switches parts (B23JP and B23HW) compatible with applications rated for 20V?

A: Yes. Both NKK Switches parts are rated for 28V AC/DC, which exceeds the 20V requirement of the original TL49P000000. Higher voltage ratings provide backward compatibility for lower-voltage applications. Electrical performance in 20V circuits is maintained.

Q: Does packaging type affect electrical performance or compatibility?

A: No. Packaging type (Bulk vs. Tray) affects procurement and handling logistics only. Electrical specifications, circuit performance, and component functionality remain identical regardless of packaging format. Verify packaging requirements based on procurement workflow and inventory management procedures.

Q: What is the significance of the 50,000-cycle electrical life rating on the NKK Switches parts compared to the 30,000-cycle rating on the TL49P000000?

A: The 50,000-cycle rating on NKK Switches parts (B23JP and B23HW) indicates extended operational durability compared to the 30,000-cycle specification of the TL49P000000. This higher rating provides additional margin for applications requiring extended switch cycle life. Both ratings are sufficient for standard industrial and commercial switching applications.

Q: Can the B23HW Wire Wrap termination be adapted to PC Pin PCB pads?

A: Wire Wrap and PC Pin terminations are mechanically and electrically distinct. Adaptation is not recommended. If the target application requires PC Pin termination, select the B23JP (NKK Switches) or 200MDP3T2B2M2RE (E-Switch) instead.
