DH2CB1PA Equivalent & Substitute Parts

Part Overview

The DH2CB1PA is a snap action SPDT switch manufactured by ZF Electronics, designed for chassis mount applications with a 500mA DC current rating at 30V. This component features a lever with simulated roller actuator and solder lug termination, suitable for applications requiring reliable switching with moderate electrical and mechanical cycling demands.

The DH2CB1PA is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or maintenance requirements for systems utilizing this switch architecture.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DH2CB1PA is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained for functional compatibility
• Current Rating: 500mA DC minimum requirement
• Voltage Rating: 30V DC minimum requirement
• Actuator Type: Lever with simulated roller mechanism
• Mounting Type: Chassis mount configuration
• Termination Style: Solder lug connections
• Operating Temperature Range: -25°C to 70°C minimum envelope
• Ingress Protection: IP40 or higher
• Compliance: RoHS3 compliance required

The DHGC-B1LA qualifies as a manufacturer-recommended substitute based on matching these core electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The DHGC-B1LA is designated as the manufacturer-recommended substitute for the obsolete DH2CB1PA. Both components are manufactured by ZF Electronics and share identical electrical specifications: SPDT circuit configuration, 500mA DC current rating, and 30V DC voltage rating.

The DHGC-B1LA carries active product status, ensuring ongoing availability and supply chain support. This transition from the obsolete DH2CB1PA to the active DHGC-B1LA provides design continuity while enabling access to current manufacturing and support resources.

Frequently Asked Questions (FAQ)

Q: Can the DHGC-B1LA directly replace the DH2CB1PA in existing designs?

A: The DHGC-B1LA is the manufacturer-recommended substitute and matches the critical electrical parameters (SPDT, 500mA, 30V). Mechanical and environmental specifications for the DHGC-B1LA should be confirmed against your specific application requirements before implementation.

Q: Why is the DH2CB1PA classified as obsolete?

A: The DH2CB1PA has reached end-of-life status. The DHGC-B1LA represents the current active equivalent from the same manufacturer, ensuring continued access to functionally equivalent switching solutions.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by matching circuit configuration (SPDT), current rating (500mA DC), voltage rating (30V DC), actuator type, mounting configuration, termination style, and operating temperature range. All substitute parts must maintain these specifications.

Q: Is the DHGC-B1LA RoHS compliant?

A: The DH2CB1PA is ROHS3 compliant. Compliance status for the DHGC-B1LA should be confirmed with the manufacturer or component documentation.

Q: What inventory status should I expect for these parts?

A: The DH2CB1PA shows 8094 pieces in stock as new original inventory. The DHGC-B1LA shows 1030 pieces in stock as new original inventory. Availability may vary based on current demand and supply conditions.
