DH4C-C6AA Equivalent & Substitute Parts

Part Overview

The DH4C-C6AA is an SPDT snap action switch manufactured by ZF Electronics, designed for through-hole, right-angle mounting applications. This component features a 50mA DC current rating at 30V with a round pin plunger actuator and On-Mom switch function. The part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications requiring SPDT switching functionality with comparable electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DH4C-C6AA are identified based on the following critical parameters that define functional equivalence:

Mandatory Matching Parameters:

• Circuit Configuration: SPDT (Single Pole Double Throw)
• Switch Function: On-Mom (Momentary)
• Mounting Type: Through Hole, Right Angle
• Termination Style: PC Pin
• RoHS Compliance: ROHS3 Compliant

Allowable Parameter Variations: The substitute parts TS0101F020V1, TS0101F020V2, TS0101F020V3, and TS0101F020V4 (all E-Switch TS series) meet the core functional requirements. These parts maintain identical SPDT circuit configuration and On-Mom function. While the substitute parts feature different actuator geometry (Lever, Straight vs. Round Pin Plunger), different current ratings (300mA vs. 50mA), and different voltage ratings (6V vs. 30V), they are listed as direct substitutes in the provided specification data, indicating they are acceptable alternatives within the application context.

Parameter Comparison

Engineering Selection Recommendations

All four E-Switch TS series substitute parts (TS0101F020V1, TS0101F020V2, TS0101F020V3, TS0101F020V4) are active products with current manufacturing support, providing supply continuity for applications previously using the obsolete DH4C-C6AA. All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) ratings, matching the original component's environmental and regulatory status.

The substitute parts offer enhanced reliability specifications with defined electrical life (50,000 cycles) and mechanical life (100,000 cycles), whereas the original DH4C-C6AA does not specify these parameters. The substitute parts also support an extended operating temperature range (-25°C to 85°C) compared to the original (-25°C to 70°C).

Selection among the four substitute part numbers should be based on application-specific requirements and inventory availability. All four parts are functionally equivalent with identical electrical and mechanical characteristics.

Frequently Asked Questions (FAQ)

Q: Why are the TS0101 series parts considered substitutes for the DH4C-C6AA despite different voltage and current ratings?

A: Substitution is based on the provided specification data, which explicitly lists these parts as equivalent alternatives. The core functional parameters—SPDT circuit configuration, On-Mom switch function, through-hole right-angle mounting, and PC pin termination—are identical. Voltage and current rating differences do not preclude substitution when the application requirements fall within the substitute part's electrical specifications.

Q: What is the difference between TS0101F020V1, TS0101F020V2, TS0101F020V3, and TS0101F020V4?

A: These four part numbers are electrically and mechanically identical. The differences are in packaging designation and inventory availability. All four parts share the same base product number (TS0101) and identical specifications. Selection can be based on inventory levels or packaging preferences.

Q: Are there any mechanical compatibility concerns when substituting the DH4C-C6AA with TS0101 series parts?

A: Both the original and substitute parts feature through-hole, right-angle mounting with PC pin termination, ensuring mechanical compatibility with existing PCB layouts. However, the actuator geometry differs (round pin plunger vs. lever straight), and the operating position varies slightly (0.220" vs. 0.264"). These differences should be evaluated within the specific mechanical envelope constraints of the application.

Q: Do the substitute parts meet the same compliance standards as the original DH4C-C6AA?

A: Yes. All substitute parts are ROHS3 compliant and carry MSL 1 (Unlimited) ratings, matching the original component's regulatory status. Both the original and substitute parts are classified as EAR99 for export control purposes and share the same HTSUS code (8536.50.7000).

Q: What is the inventory status for these substitute parts?

A: All four E-Switch TS0101 series substitute parts are currently in stock as new original components. TS0101F020V1 has 1908 units available, TS0101F020V2 has 1111 units, TS0101F020V3 has 994 units, and TS0101F020V4 has 1820 units in inventory.
