DH4C-C6LA Equivalent & Substitute Parts

Part Overview

The DH4C-C6LA is a snap-action SPDT switch manufactured by ZF Electronics, designed for through-hole, right-angle mounting applications. This component features a lever with simulated roller actuator, rated for 50mA DC at 30V, with an operating force of 50gf. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and component sourcing.

Substitute Part Grouping Explanation

Substitute parts for the DH4C-C6LA are identified from the E-Switch TS0101 series based on the following critical parameters:

Matching Parameters:

• Circuit configuration: SPDT
• Switch function: On-Mom
• Mounting type: Through Hole, Right Angle
• Termination style: PC Pin
• Operating position: 0.264" (6.7mm)
• RoHS compliance: ROHS3 Compliant
• MSL rating: 1 (Unlimited)

Substitute Parts:

• TS0101F020V1
• TS0101F020V2
• TS0101F020V3
• TS0101F020V4

All four substitute parts share identical electrical and mechanical specifications within the TS0101 base product family. These parts are manufactured by E-Switch and maintain active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The TS0101F020V1, TS0101F020V2, TS0101F020V3, and TS0101F020V4 are functionally equivalent substitutes for the obsolete DH4C-C6LA. All substitute parts maintain active product status, ensuring long-term component availability and supply chain continuity.

Both the main part and all substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute parts provide enhanced specifications in several areas: higher current rating (300mA versus 50mA), extended operating temperature range (-25°C to 85°C versus -25°C to 70°C), and documented electrical and mechanical life cycles (50,000 and 100,000 cycles respectively).

The substitute parts feature a straight lever actuator in place of the simulated roller actuator on the original part, and operate at 6V DC rather than 30V DC. These differences must be evaluated against specific circuit requirements. The lower operating force (20gf versus 50gf) on substitute parts represents a reduced actuation requirement.

Selection among the four substitute variants should be based on inventory availability and specific application requirements, as all four parts share identical electrical and mechanical specifications.

Frequently Asked Questions (FAQ)

Q: Can TS0101F020V1, TS0101F020V2, TS0101F020V3, and TS0101F020V4 be used interchangeably?

A: Yes. All four parts share identical circuit configuration (SPDT), switch function (On-Mom), mounting type (through hole, right angle), termination style (PC pin), operating position (0.264"), and operating temperature range (-25°C to 85°C). They differ only in packaging designation and inventory availability.

Q: What are the key differences between DH4C-C6LA and the TS0101 series substitutes?

A: The primary differences are voltage rating (30V versus 6V), current rating (50mA versus 300mA), actuator type (simulated roller versus straight lever), and operating force (50gf versus 20gf). The substitute parts also provide documented electrical and mechanical life specifications and extended temperature range.

Q: Are the substitute parts compatible with the original circuit design?

A: Compatibility depends on circuit voltage and current requirements. The substitute parts operate at 6V DC maximum, compared to the original 30V DC rating. If the original design operates above 6V, the substitute parts are not suitable. Current requirements must also be verified; the substitute parts are rated for 300mA, which exceeds the original 50mA rating.

Q: What is the difference between the four TS0101F020V variants?

A: TS0101F020V1, TS0101F020V2, TS0101F020V3, and TS0101F020V4 are electrically and mechanically identical. Differences exist only in packaging designation and current inventory levels (1908, 1111, 994, and 1820 pieces respectively).

Q: Are regulatory certifications maintained with these substitutes?

A: Yes. All substitute parts maintain ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, matching the original part's regulatory profile.

Q: What is the operating force difference, and does it matter?

A: The original DH4C-C6LA requires 50gf operating force, while the TS0101 series requires 20gf. This means the substitute parts require less finger pressure or mechanical force to actuate. Application-specific requirements must determine if this difference is acceptable.
