Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 34ADP11B1M2RT are grouped based on electrical and mechanical compatibility. The primary substitution criteria are:

Electrical Compatibility Parameters:

• Circuit configuration (DPDT required)
• Switch function (On-On required)
• Current and voltage ratings (must meet or exceed 0.4VA at 20V AC/DC)
• Operating temperature range (-30°C ~ 85°C minimum)

Mechanical Compatibility Parameters:

• Mounting type (Panel Mount required)
• Termination style (PC Pin required)
• Panel cutout dimensions (Circular - 6.35mm Dia required)
• Bushing thread (1/4-40 required)

Compliance Parameters:

• RoHS3 Compliance required
• Product Status (Active)

Substitutes are divided into two categories:

Category 1 - Direct Electrical Equivalents (0.4VA @ 20V):

• 100DP1T6B15M2RE (E-Switch)
• 2-1825138-4 (TE Connectivity ALCOSWITCH Switches)

Category 2 - Higher-Rated Alternatives (5A @ 120V):

• 100DP1T1B1M2QEH (E-Switch)
• 7201P3DCQE (C&K)
• 7201P3YCQE (C&K)
• 7201SDCQE (C&K)
• 7201SPYCQE (C&K)
• 7201SYCQE (C&K)

Parameter Comparison

Engineering Selection Recommendations

Direct Electrical Equivalents (Recommended for 1:1 Replacement):

The 100DP1T6B15M2RE (E-Switch) and 2-1825138-4 (TE Connectivity ALCOSWITCH Switches) are direct electrical equivalents to the 34ADP11B1M2RT. Both parts maintain identical voltage and current ratings (0.4VA @ 20V AC/DC), DPDT configuration, and mechanical mounting specifications. Both are ROHS3 Compliant and Active products. The 100DP1T6B15M2RE features epoxy sealed terminals and maintains 40,000 cycle electrical life. The 2-1825138-4 provides an alternative from TE Connectivity with epoxy sealed terminals, though electrical life is rated at 6,000 cycles.

Higher-Rated Alternatives (For Applications Requiring Enhanced Capacity):

The 100DP1T1B1M2QEH (E-Switch) and C&K series parts (7201SYCQE, 7201P3YCQE, 7201SDCQE, 7201SPYCQE, 7201P3DCQE) are rated for 5A at 120V AC/DC, providing significantly higher electrical capacity than the original part. These alternatives are suitable for applications where the original 0.4VA rating is insufficient. All C&K parts feature 100,000 cycle electrical life, exceeding the original specification. All substitute parts maintain the required panel mount configuration, PC pin termination, and 1/4-40 bushing thread.

Compliance Considerations:

All substitute parts are ROHS3 Compliant and maintain Active product status. The 2-1825138-4 and all C&K series parts are REACH Affected, whereas the original 34ADP11B1M2RT and 100DP1T6B15M2RE are REACH Unaffected. This distinction is relevant for applications subject to REACH regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 100DP1T6B15M2RE be used as a direct replacement for the 34ADP11B1M2RT?

A: Yes. The 100DP1T6B15M2RE maintains identical electrical ratings (0.4VA @ 20V AC/DC), DPDT configuration, and mechanical specifications including panel cutout dimensions and bushing thread. Both parts are ROHS3 Compliant and Active. The primary difference is the actuator type: the 100DP1T6B15M2RE uses a Flat Anti-Rotation actuator at 12.30mm length, compared to the Standard Round actuator at 10.41mm on the original part. This difference affects panel aesthetics and actuator feel but does not impact electrical function.

Q: What is the difference between the direct equivalents and the higher-rated alternatives?

A: Direct equivalents (100DP1T6B15M2RE and 2-1825138-4) maintain the original 0.4VA @ 20V rating and are suitable for low-power applications. Higher-rated alternatives (100DP1T1B1M2QEH and C&K series) are rated for 5A @ 120V AC/DC and are intended for applications requiring greater electrical capacity. Higher-rated parts are electrically backward-compatible with the original application but introduce additional design margin.

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

A: No. The original 34ADP11B1M2RT is supplied in Bulk packaging. The 100DP1T6B15M2RE and 100DP1T1B1M2QEH are also supplied in Bulk. However, some C&K alternatives are supplied in Tray packaging (7201P3DCQE, 7201SDCQE, 7201SPYCQE). Packaging differences do not affect component function but may impact procurement and handling procedures.

Q: What is the significance of the actuator type differences among substitute parts?

A: Actuator type affects the mechanical interface and user interaction with the switch. The original part uses a Standard Round actuator. The 100DP1T6B15M2RE uses a Flat Anti-Rotation actuator, and various C&K parts use Standard Round, Flat Anti-Rotation, or Anti-Rotation types. These differences do not affect electrical performance but influence panel mounting aesthetics and actuator engagement characteristics. Actuator length variations (ranging from 10.41mm to 13.21mm) may affect panel depth requirements.

Q: Are there electrical life differences between the original and substitute parts?

A: Yes. The original 34ADP11B1M2RT is rated for 40,000 electrical cycles. The 100DP1T6B15M2RE maintains this rating. The 2-1825138-4 is rated for only 6,000 cycles, representing a significant reduction. The C&K series parts are rated for 100,000 cycles, providing enhanced durability. Electrical life selection depends on application duty cycle requirements.

Q: What REACH compliance considerations apply to substitute selection?

A: The original 34ADP11B1M2RT is REACH Unaffected. The 100DP1T6B15M2RE is also REACH Unaffected. However, the 2-1825138-4 and all C&K series parts are REACH Affected. For applications subject to REACH regulatory requirements, the REACH Unaffected alternatives (34ADP11B1M2RT or 100DP1T6B15M2RE) are preferred.

Q: Can higher-rated alternatives be used in applications designed for the original 0.4VA part?

A: Yes. Higher-rated alternatives such as the 100DP1T1B1M2QEH and C&K series parts are electrically backward-compatible with applications designed for the 0.4VA @ 20V original part. The higher current and voltage ratings provide additional design margin and do not create incompatibility. However, the application circuit must accommodate the different actuator types and lengths if panel integration is critical.
