DH3C-C6LA Snap Action Switch SPDT Equivalent & Substitute Parts

Part Overview

The DH3C-C6LA is a snap action switch manufactured by ZF Electronics, classified as SPDT (Single Pole Double Throw) with On-Mom functionality. This component is rated for 0.3A DC at 30V and features a lever-actuated design with right-angle through-hole mounting. The part is currently obsolete, making equivalent substitutes necessary for ongoing design support and production continuity. Substitute parts must maintain electrical compatibility while accommodating application-specific voltage and mechanical requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DH3C-C6LA is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom
• Current rating: 300mA DC minimum
• Mounting type: Through Hole, Right Angle
• Termination style: PC Pin
• Operating position: 0.264" (6.7mm)

Application-Dependent Parameters:

• Voltage rating: Must equal or exceed application requirement (30V for DH3C-C6LA)
• Operating temperature range: Must encompass application operating conditions
• Actuator type: Mechanical differences acceptable if functional requirements are met

The substitute parts TS0101F020V1, TS0101F020V2, TS0101F020V3, and TS0101F020V4 (all E-Switch TS series) share identical circuit configuration, current rating, mounting type, termination style, and operating position. These parts are functionally equivalent for applications operating at 6V DC or lower. Applications requiring the full 30V rating of the original DH3C-C6LA cannot use these substitutes without circuit redesign.

Parameter Comparison

Engineering Selection Recommendations

Voltage Rating Constraint: The DH3C-C6LA operates at 30V DC, while all E-Switch TS series substitutes are rated for 6V DC maximum. Direct substitution is only applicable for applications operating at 6V DC or lower. For applications requiring 30V operation, alternative sources must be identified.

Product Status Advantage: All E-Switch TS series parts (TS0101F020V1, TS0101F020V2, TS0101F020V3, TS0101F020V4) maintain active product status, ensuring long-term availability and supply chain continuity compared to the obsolete DH3C-C6LA.

Compliance Alignment: Both the original part and all substitutes are ROHS3 compliant and REACH unaffected, maintaining regulatory compliance across substitution options.

Temperature Operating Range: E-Switch substitutes provide an extended upper temperature limit of 85°C compared to the DH3C-C6LA specification of 70°C, offering improved thermal margin for applications within the 6V rating.

Mechanical Specifications: Substitute parts feature straight lever actuators versus the simulated roller design of the original. Both designs maintain identical operating position (0.264" / 6.7mm) and through-hole right-angle mounting, ensuring mechanical compatibility in PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can TS0101F020V1, TS0101F020V2, TS0101F020V3, or TS0101F020V4 replace DH3C-C6LA in a 30V application?

A: No. The E-Switch TS series parts are rated for 6V DC maximum. Using them in a 30V circuit will result in component failure. Substitution is only valid for applications operating at 6V DC or lower.

Q: What are the differences between TS0101F020V1, TS0101F020V2, TS0101F020V3, and TS0101F020V4?

A: These four part numbers are electrically and mechanically identical. All share the same circuit configuration, current rating, voltage rating, actuator type, mounting configuration, and performance specifications. Differences exist only in inventory lot tracking and packaging designation.

Q: Are the substitute parts pin-compatible with the DH3C-C6LA?

A: Yes. Both the original part and all substitutes use PC Pin termination style and identical through-hole right-angle mounting, ensuring direct PCB footprint compatibility.

Q: What is the impact of the different actuator types (simulated roller vs. straight lever)?

A: Both actuator designs maintain the same operating position (0.264" / 6.7mm) and switch function (On-Mom). The mechanical difference does not affect electrical performance or PCB mounting. Actuator choice depends on application-specific ergonomic or mechanical requirements.

Q: Do the substitute parts have longer operational life than the original?

A: Yes. E-Switch TS series parts specify 50,000 electrical cycles and 100,000 mechanical cycles, while the DH3C-C6LA does not provide life cycle specifications. This represents a documented performance advantage for the substitutes.

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

A: All E-Switch TS series substitutes are supplied in bulk packaging. The original DH3C-C6LA packaging format is not specified in the available data.
