Substitute Part Grouping Explanation

Substitute parts for the DH2CB1AA are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Circuit configuration: SPDT
• Current rating: 500mA DC
• Voltage rating: 30V DC
• Actuator type: Round pin plunger
• Mounting type: Chassis mount
• Termination style: Solder lug
• Switch function: Momentary (On-Mom)

Both substitute parts (DHGC-B1AA and DHGC-C5AA) are manufactured by ZF Electronics and maintain identical electrical specifications to the original DH2CB1AA. These parts are currently in active production status, ensuring long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

The DH2CB1AA is obsolete and no longer available from the manufacturer. Both DHGC-B1AA and DHGC-C5AA are direct functional equivalents with active production status, ensuring procurement viability for new designs and replacement applications.

DHGC-B1AA is suitable for applications requiring immediate availability with confirmed inventory of 829 pieces.

DHGC-C5AA offers higher inventory levels (1,105 pieces) and includes documented ECCN and HTSUS classifications, supporting applications with regulatory or export documentation requirements.

Both substitutes maintain identical electrical performance specifications and are manufactured by the same original equipment manufacturer, ensuring compatibility with existing circuit designs and mechanical assemblies.

Frequently Asked Questions (FAQ)

Q: Can DHGC-B1AA and DHGC-C5AA be used interchangeably with DH2CB1AA?

A: Yes. Both substitute parts maintain identical electrical ratings (500mA at 30V DC), circuit configuration (SPDT), and switch function (momentary). They are manufactured by ZF Electronics and are functionally equivalent for direct replacement applications.

Q: What is the primary reason for substitution?

A: The DH2CB1AA is obsolete and no longer manufactured. DHGC-B1AA and DHGC-C5AA are active production alternatives from the same manufacturer with identical electrical and mechanical specifications.

Q: Are there packaging differences between the original and substitute parts?

A: Packaging information is not specified for the substitute parts. Mechanical compatibility should be confirmed based on chassis mount dimensions and solder lug terminal specifications for your specific application.

Q: Which substitute part should be selected for new designs?

A: Either DHGC-B1AA or DHGC-C5AA is appropriate for new designs. Selection may be based on inventory availability or regulatory documentation requirements. DHGC-C5AA includes ECCN and HTSUS classifications if export compliance documentation is needed.

Q: Are the substitute parts RoHS compliant?

A: RoHS compliance status is not specified for DHGC-B1AA and DHGC-C5AA. The original DH2CB1AA is ROHS3 compliant. Compliance verification should be obtained from the manufacturer if required for your application.
