DRD16 Rotary DIP Switch Equivalent & Substitute Parts

Part Overview

The DRD16 is a hexadecimal rotary DIP switch manufactured by TE Connectivity ALCOSWITCH Switches, designed for through-hole mounting applications requiring tool-actuated position selection. This component operates at 0.4VA and 20VAC/DC, featuring a flush, recessed actuator with gold-plated copper alloy contacts. The DRD16 is classified as obsolete, necessitating identification of active equivalent parts to maintain design continuity and ensure procurement availability for new production and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DRD16 is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain identical specifications in the following categories:

Electrical Parameters: Circuit configuration (hexadecimal), number of positions (16), current rating (0.4VA), and voltage rating (20VAC/DC) must be identical to ensure functional compatibility within the circuit design.

Mechanical Parameters: Actuator type (rotary for tool), actuator level (flush, recessed), mounting type (through hole), termination style (PC pin), pitch (0.100"), and height above board (0.256") must match to ensure physical compatibility with existing PCB layouts and mechanical assemblies.

Material and Environmental Parameters: Contact material (copper alloy), contact finish (gold), operating temperature range (-30°C ~ 85°C), mechanical life (10,000 steps), and electrical life (10,000 steps) must be equivalent to maintain reliability and performance characteristics.

The DRD16E04 meets all these criteria and is classified as an active product, providing a direct functional and physical replacement.

Engineering Selection Recommendations

The DRD16E04 is the direct equivalent and recommended substitute for the obsolete DRD16. Both parts are manufactured by TE Connectivity ALCOSWITCH Switches and share identical electrical and mechanical specifications across all critical parameters.

Product Status Consideration: The DRD16 is classified as obsolete, while the DRD16E04 is active. Selection of the DRD16E04 ensures continued procurement availability and manufacturer support.

Compliance Enhancement: The DRD16E04 carries ROHS3 compliance certification, providing improved environmental and regulatory alignment compared to the DRD16, for which RoHS status was not specified.

Functional Improvement: The DRD16E04 includes washable capability, an enhancement over the non-washable DRD16, providing additional flexibility for manufacturing processes that require cleaning operations.

Packaging Consideration: The DRD16E04 is supplied in tube packaging, which is standard for active production components and facilitates automated assembly processes.

The DRD16E04 is a direct form, fit, and function replacement suitable for both new designs and field replacements of existing DRD16 installations.

Frequently Asked Questions (FAQ)

Q: Can the DRD16E04 be used as a direct replacement for the DRD16 in existing designs?
