DG23-B2RA Equivalent & Substitute Parts

Part Overview

The DG23-B2RA is a snap-action switch manufactured by ZF Electronics, configured as a Single Pole Double Throw (SPDT) device with momentary on-function operation. This through-hole, right-angle mounted switch is rated for 50mA DC at 30V with a lever roller actuator and PC pin termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing maintenance, repair, and legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DG23-B2RA is determined by electrical and mechanical parameter alignment within the snap-action switch category. The primary substitution criteria are:

Electrical Parameters: Circuit configuration (SPDT), current rating (50mA DC), and voltage rating (30V DC) must match or exceed the original specification.

Mechanical Parameters: Actuator type (lever/roller), mounting configuration (through-hole, right-angle), and termination style (PC pin) establish physical compatibility with existing PCB layouts and mechanical assemblies.

Operational Parameters: Operating force (60gf), travel distances (operating position, pretravel, differential travel, overtravel), and temperature range (-25°C to 85°C) define functional performance boundaries.

Lifecycle Parameters: Electrical life (200,000 cycles minimum) and mechanical life (1,000,000 cycles minimum) establish durability requirements for the application.

Compliance Parameters: RoHS3 compliance and MSL 1 rating ensure regulatory and environmental compatibility.

The DGG3-E5RD meets these substitution criteria as a functionally equivalent alternative from the same manufacturer.

Parameter Comparison

Engineering Selection Recommendations

The DGG3-E5RD is the manufacturer-recommended substitute for the obsolete DG23-B2RA. Both components are manufactured by ZF Electronics and share identical electrical ratings (SPDT, 50mA DC, 30V DC) and termination configuration (PC pin). The DGG3-E5RD maintains active product status, ensuring ongoing availability and supply chain continuity.

Selection of the DGG3-E5RD is appropriate for applications requiring direct replacement of the DG23-B2RA. The active product status of the substitute provides long-term sourcing reliability compared to the obsolete original part number.

Frequently Asked Questions (FAQ)

Q: Can the DGG3-E5RD directly replace the DG23-B2RA in existing assemblies?

A: Yes. Both parts share identical electrical specifications (SPDT, 50mA DC, 30V DC) and PC pin termination, establishing direct functional compatibility. Mechanical compatibility depends on matching actuator type, mounting configuration, and physical dimensions, which are not fully specified in the available data for the DGG3-E5RD.

Q: What is the primary reason for substitution?

A: The DG23-B2RA is obsolete. The DGG3-E5RD is the manufacturer-recommended active alternative, ensuring continued component availability and supply chain support.

Q: Are there packaging differences between these parts?

A: The DG23-B2RA packaging is not specified in the available data. The DGG3-E5RD is supplied in bulk packaging. Packaging format may affect procurement quantities and handling procedures.

Q: Do both parts meet the same compliance standards?

A: The DG23-B2RA is ROHS3 compliant. RoHS compliance status for the DGG3-E5RD is not specified in the available data. Compliance verification is recommended before final selection.

Q: What electrical parameters must match for substitution?

A: Circuit configuration (SPDT), current rating (50mA DC), voltage rating (30V DC), and termination style (PC pin) are the critical electrical parameters that establish substitution eligibility.
