Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 34ASP37T7M2RT is determined by the following critical parameters:

Mechanical Compatibility:

• Panel cutout dimensions (Circular - 11.91mm Dia)
• Bushing thread specification (15/32-32)
• Actuator type and length (Standard Round, 12.37mm)
• Termination style (PC Pin)

Electrical Compatibility:

• Circuit configuration (SPDT)
• Switch function (On-Off-On)
• Operating temperature range (-30°C ~ 85°C)
• Electrical life rating (40,000 Cycles)

Regulatory Compliance:

• RoHS3 compliance status
• Moisture sensitivity level (MSL 1)

The identified substitute part 7103T1CWCQE from C&K satisfies all mechanical interface requirements and maintains equivalent circuit topology and environmental specifications. This part is suitable for applications where the higher electrical ratings (5A at 120V AC / 28V DC) do not create design constraints.

Parameter Comparison

Engineering Selection Recommendations

34ASP37T7M2RT Selection Criteria:

• Applications requiring exact 0.4VA / 20V electrical specifications
• Designs where component cost optimization is prioritized
• Systems with established qualification to Grayhill 34A series components
• Active production status ensures supply continuity

7103T1CWCQE Selection Criteria:

• Applications operating at higher voltage or current levels within the 5A / 120V AC / 28V DC envelope
• Designs requiring IP67 ingress protection (dust tight, waterproof)
• Systems benefiting from epoxy sealed terminals for enhanced environmental resistance
• Designs where C&K 7000 series qualification is established
• Active production status with higher inventory availability (1121 Pcs vs 739 Pcs)

Both parts maintain ROHS3 compliance, MSL 1 rating, and equivalent mechanical interfaces. Selection between these parts depends on application voltage/current requirements and environmental protection needs.

Frequently Asked Questions (FAQ)

Q: Can 7103T1CWCQE directly replace 34ASP37T7M2RT in all applications?

A: Mechanical and functional replacement is direct due to identical panel cutout dimensions, bushing thread, actuator specifications, and circuit topology. However, electrical circuit design must accommodate the higher ratings of 7103T1CWCQE (5A / 120V AC / 28V DC). If the application circuit is designed for 0.4VA / 20V operation, 7103T1CWCQE will function correctly but represents electrical over-specification.

Q: What are the key mechanical compatibility factors?

A: Panel cutout diameter (11.91mm circular), bushing thread (15/32-32), actuator type (standard round), actuator length (12.37mm), and termination style (PC pin) must match exactly. Both parts satisfy these requirements.

Q: Does 7103T1CWCQE provide additional environmental protection?

A: Yes. 7103T1CWCQE includes IP67 ingress protection rating and epoxy sealed terminals, whereas 34ASP37T7M2RT does not specify ingress protection. This makes 7103T1CWCQE suitable for applications with moisture or dust exposure requirements.

Q: Are both parts RoHS3 compliant?

A: Yes. Both 34ASP37T7M2RT and 7103T1CWCQE are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity level.

Q: What is the electrical life expectancy for both parts?

A: Both parts are rated for 40,000 electrical cycles, providing equivalent operational longevity.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. For designs operating within 0.4VA / 20V specifications without environmental protection needs, either part is suitable. For designs requiring higher electrical ratings or IP67 protection, 7103T1CWCQE is the appropriate selection. Both parts are actively produced.
