DRD16CRA Equivalent & Substitute Parts

Part Overview

The DRD16CRA is a rotary DIP switch manufactured by TE Connectivity ALCOSWITCH Switches, designed for hexadecimal complement applications requiring 16-position switching capability. This through-hole, right-angle mounted component operates at 0.4VA and 20VAC/DC, featuring a tool-actuated rotary mechanism with flush, recessed actuator level. The DRD16CRA is classified as obsolete, necessitating identification of active equivalent components to maintain design continuity and ensure long-term component availability for new production and field service applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DRD16CRA is based on electrical and mechanical parameter equivalence. The substitute part 1825008-3 maintains identical specifications across all critical switching parameters: hexadecimal complement circuit configuration, 16-position capability, 0.4VA current rating, and 20VAC/DC voltage rating. Physical compatibility is preserved through matching mounting type (through-hole, right-angle), actuator type (rotary for tool), pitch (0.100"), and board height (0.413"). Operating temperature range, mechanical life, and electrical life specifications are identical between the main part and substitute.

The primary distinction between DRD16CRA and 1825008-3 lies in product status and regulatory compliance. The DRD16CRA is obsolete and RoHS non-compliant, while 1825008-3 is active and ROHS3 compliant. Additionally, 1825008-3 features washable capability, whereas the DRD16CRA does not.

Parameter Comparison

Engineering Selection Recommendations

The DRD16CRA is obsolete and no longer supported by the manufacturer. Direct substitution with part number 1825008-3 is appropriate for all new designs and production applications. The 1825008-3 maintains complete electrical and mechanical compatibility with the DRD16CRA while offering the advantage of active product status and ROHS3 compliance.

For applications subject to RoHS directives or environmental regulations, the 1825008-3 is the required selection. The washable capability of 1825008-3 provides additional process flexibility for manufacturing environments requiring post-assembly cleaning operations.

Existing inventory of DRD16CRA components may continue to be used in field service and repair applications where RoHS compliance is not mandated, provided that supply remains available. However, transition to 1825008-3 is recommended for long-term supply chain stability and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can 1825008-3 be used as a direct replacement for DRD16CRA in existing designs?
