Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7301MHZGE are identified based on strict alignment of the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration: 3PDT
• Switch function: On-On
• Mounting type: Panel Mount
• Panel cutout dimensions: Circular - 6.35mm Dia
• Bushing thread: 1/4-40
• Termination style: Solder Lug
• Operating temperature range: -30°C ~ 85°C
• Actuator type: Standard Round

Electrical Rating Compatibility: Substitutes must maintain equivalent or superior current and voltage ratings. The 7301MHZGE operates at 5A (AC/DC) with 120V AC and 28V DC ratings. Parts meeting these exact electrical specifications are classified as direct equivalents. Parts with reduced electrical ratings are classified as limited-use substitutes.

Mechanical Compatibility: All substitute parts share identical panel mounting geometry, bushing thread specifications, and solder lug termination, ensuring direct mechanical interchangeability without panel modification.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Full Substitution): The E-Switch 1003P1T2B1M1QE provides direct equivalence to the 7301MHZGE. Both parts share identical electrical ratings (5A at 120V AC / 28V DC), matching actuator length (5.08mm), and equivalent mechanical mounting specifications. Both are ROHS3 compliant and active products. The primary difference is reduced electrical life (40,000 cycles versus 100,000 cycles), which may be acceptable depending on application duty cycle requirements.

Compatible Substitute (Mechanical Compatibility, Reduced Electrical Life): The E-Switch 1003P1T1B1M1QEH matches all electrical ratings and mechanical specifications of the 7301MHZGE but features an extended actuator length (10.41mm versus 5.08mm). This part is suitable for applications where panel depth permits the longer actuator. Electrical life is reduced to 40,000 cycles. REACH status differs (REACH Unaffected versus REACH Affected), which may be relevant for specific regulatory environments.

Limited-Use Substitute (Reduced Electrical Ratings): The E-Switch 1003P1T1B1M1RE is mechanically compatible but operates at significantly reduced electrical ratings (0.4VA at 20V AC/DC versus 5A at 120V AC / 28V DC). This part is suitable only for low-power signal switching applications and is not appropriate for the full electrical specification of the 7301MHZGE.

All substitute parts maintain ROHS3 compliance and active product status, ensuring regulatory alignment and supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 1003P1T2B1M1QE be used as a direct replacement for the C&K 7301MHZGE? A: Yes. The 1003P1T2B1M1QE provides direct mechanical and electrical compatibility. Both parts feature identical panel cutout dimensions (6.35mm circular), bushing thread (1/4-40), actuator length (5.08mm), and electrical ratings (5A at 120V AC / 28V DC). The primary difference is electrical life specification (40,000 cycles versus 100,000 cycles).

Q: What is the significance of the different actuator lengths in the substitute parts? A: Actuator length determines the physical extension of the toggle lever from the panel surface. The 7301MHZGE and 1003P1T2B1M1QE both feature 5.08mm actuators, suitable for standard panel depths. The 1003P1T1B1M1QEH and 1003P1T1B1M1RE feature 10.41mm actuators, requiring greater panel depth clearance. Selection depends on available panel space and operator accessibility requirements.

Q: Is the E-Switch 1003P1T1B1M1RE suitable as a substitute? A: The 1003P1T1B1M1RE is mechanically compatible but electrically limited. It operates at 0.4VA and 20V maximum, compared to the 7301MHZGE specification of 5A at 120V AC / 28V DC. This part is suitable only for low-power applications and cannot handle the full electrical load of the original specification.

Q: How do electrical life ratings affect part selection? A: Electrical life specifies the number of switching cycles a part can withstand before performance degradation. The 7301MHZGE is rated for 100,000 cycles, while E-Switch substitutes are rated for 40,000 cycles. Selection should account for application duty cycle. High-frequency switching applications may require the higher-rated original part.

Q: Are all substitute parts ROHS3 compliant? A: Yes. The 7301MHZGE and all listed E-Switch substitutes (1003P1T2B1M1QE, 1003P1T1B1M1QEH, 1003P1T1B1M1RE) are ROHS3 compliant, ensuring regulatory alignment for applications requiring hazardous substance restrictions.

Q: What is the difference in REACH status between the main part and substitutes? A: The C&K 7301MHZGE is REACH Affected, indicating it may contain substances of concern under REACH regulations. The E-Switch substitutes are REACH Unaffected. For applications in REACH-regulated markets, the E-Switch parts may offer simplified compliance documentation.
