Primary Substitution Criteria:

Circuit configuration: DPDT
Switch function: On-On
Mounting type: Panel Mount
Termination style: Solder Lug
Panel cutout dimensions: Circular - 6.35mm Dia
Bushing thread: 1/4-40
Operating temperature range: -30°C to 85°C
Actuator material: Brass, Chrome Plated

Electrical Performance Criteria:

Current rating: 5A (AC/DC) minimum
Voltage rating - AC: 120V minimum
Voltage rating - DC: 28V minimum

Substitute parts are grouped into two categories based on electrical performance alignment:

Category A - Full Electrical Equivalents (5A @ 120V AC / 28V DC): Parts meeting or exceeding the main part's electrical specifications with identical circuit and mechanical interfaces.

Category B - Reduced Electrical Rating Substitutes (0.4VA @ 20V AC/DC): Parts with lower electrical ratings suitable only for applications with reduced power requirements. These are not interchangeable for the original 5A @ 120V specification.

Engineering Selection Recommendations

For Direct Replacement (5A @ 120V AC / 28V DC Applications):

The C&K 7201SYZQE is the primary equivalent, offering identical electrical ratings and mechanical interface specifications. Both parts are ROHS3 compliant and feature solder lug termination with 1/4-40 bushing threads. The 7201SYZQE is currently in active production status with 2000 units in stock, providing supply continuity for the obsolete 7201SYZQES.

E-Switch 100DP1T1B9M1QEH and 100DP1T6B11M1QEH provide full electrical equivalence with 5A @ 120V AC / 28V DC ratings. Both are ROHS3 compliant and active products. The 100DP1T6B11M1QEH features a flat anti-rotation actuator design, which may provide enhanced mechanical stability in certain panel configurations compared to the standard round actuator of the original part.

Grayhill Inc. 34ADP11B1M1GT, 34ADP11B3M1QT, and 34ADP13B1M1QT all meet electrical requirements with 5A @ 125V AC ratings, exceeding the original 120V specification. These parts are active products with ROHS3 compliance. Actuator length variations (10.41mm, 12.19mm, and 13.97mm respectively) allow selection based on panel depth requirements.

For Reduced Power Applications (0.4VA @ 20V AC/DC):

E-Switch 100DP1T1B1M1REH, 100DP1T6B11M1REH and Grayhill Inc. 34ADP11B9M1RT are suitable only for applications with significantly reduced electrical requirements. These parts are not interchangeable with the original 7201SYZQES for 5A @ 120V applications.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance status. Grayhill 34ADP11B3M1QT carries RoHS Compliant designation rather than ROHS3; verify compliance requirements for your specific application before selection.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M1REH substitute for the C&K 7201SYZQES?

A: No. The 100DP1T1B1M1REH is rated for 0.4VA @ 20V AC/DC, which is insufficient for applications requiring 5A @ 120V AC. This part is suitable only for low-power signal switching applications.

Q: What is the primary difference between the C&K 7201SYZQE and 7201SYZQES?

A: The 7201SYZQE is the active production equivalent of the obsolete 7201SYZQES. Both share identical electrical ratings (5A @ 120V AC / 28V DC), circuit configuration (DPDT), and mechanical specifications. The primary difference is product status: 7201SYZQES is obsolete while 7201SYZQE is actively manufactured.

Q: Are actuator length differences significant when selecting a substitute?

A: Actuator length affects panel depth requirements and operator ergonomics. The original 7201SYZQES features a 10.67mm actuator. Substitutes range from 10.41mm to 16.26mm. Verify panel cutout depth compatibility before selection. Shorter actuators (10.41mm) are suitable for shallow panels, while longer actuators (16.26mm) require deeper panel cavities.

Q: Do all substitute parts use solder lug termination?

A: Yes. All listed substitute parts maintain solder lug termination style, ensuring compatibility with existing PCB layouts and wiring harnesses designed for the original 7201SYZQES.

Q: What is the significance of the flat anti-rotation actuator in the E-Switch 100DP1T6B11M1QEH?

A: The flat anti-rotation design prevents unintended rotation of the actuator during operation or installation. This feature provides enhanced mechanical stability compared to standard round actuators, particularly in applications subject to vibration or frequent manual actuation.

Q: Can Grayhill 34ADP parts rated at 125V AC substitute for the 120V AC specification?

A: Yes. The 125V AC rating exceeds the original 120V AC requirement, providing margin for voltage variations in AC supply systems. These parts are electrically compatible and suitable for direct substitution in 120V AC applications.

Q: What packaging options are available for substitute parts?

A: The C&K 7201SYZQE is available in bulk packaging. E-Switch and Grayhill parts are supplied in bulk packaging. Verify packaging requirements for your procurement process, as some applications may require specific packaging configurations.

Q: Are all substitute parts ROHS3 compliant?

A: Most substitute parts carry ROHS3 compliance. The Grayhill 34ADP11B3M1QT is designated as RoHS Compliant rather than ROHS3. Confirm compliance certification requirements for your application before final part selection.
