DRD16SE Equivalent & Substitute Parts

Part Overview

The DRD16SE is a hexadecimal rotary DIP switch manufactured by TE Connectivity ALCOSWITCH Switches, designed for surface mount applications requiring tool actuation. This 16-position rotary switch operates at 0.4VA and 20VAC/DC, featuring a flush, recessed actuator with gold-plated copper alloy contacts. The DRD16SE is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DRD16SE is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain identical specifications in the following critical areas:

Electrical Parameters: Hexadecimal circuit configuration, 16-position count, 0.4VA current rating, and 20VAC/DC voltage rating are non-negotiable for functional compatibility.

Mechanical Parameters: Surface mount mounting type, gull wing termination style, 0.100" (2.54mm) pitch, flush recessed actuator level, and rotary tool actuation method must be preserved.

Physical Dimensions: Height above board of 0.291" (7.39mm) and length of 0.394" (10.00mm) ensure PCB layout compatibility.

Material Specifications: Copper alloy contacts with gold finish and polyphenylene sulfide body material maintain electrical performance and environmental resistance.

Environmental Ratings: Operating temperature range of -30°C to 85°C and mechanical/electrical life of 10,000 steps define the operational envelope.

Engineering Selection Recommendations

The 1-1825007-8 is a direct functional equivalent to the DRD16SE across all electrical and mechanical parameters. Both parts are manufactured by TE Connectivity ALCOSWITCH Switches within the DRD series and maintain identical specifications for hexadecimal 16-position rotary DIP switch applications.

The primary distinction between these parts is product status and regulatory compliance. The DRD16SE is classified as obsolete, while the 1-1825007-8 maintains active product status. Additionally, the 1-1825007-8 achieves ROHS3 compliance, whereas the DRD16SE is RoHS non-compliant. For new designs or production requiring current regulatory alignment, the 1-1825007-8 is the appropriate selection. For legacy system maintenance where the original DRD16SE specification must be preserved, the 1-1825007-8 provides full functional compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can the 1-1825007-8 be used as a direct replacement for the DRD16SE in existing designs?

A: Yes. The 1-1825007-8 is electrically and mechanically equivalent to the DRD16SE. All functional parameters, including hexadecimal circuit configuration, 16-position count, 0.4VA rating, 20VAC/DC voltage, surface mount gull wing termination, and dimensional specifications are identical. No design modification is required for substitution.

Q: What is the difference in packaging between these parts?

A: The DRD16SE is supplied in standard packaging, while the 1-1825007-8 is supplied in tube packaging. Both parts are identical in form, fit, and function. Packaging selection depends on assembly process requirements and inventory management practices.

Q: Why is the DRD16SE listed as obsolete?

A: The DRD16SE has been discontinued by TE Connectivity ALCOSWITCH Switches. The 1-1825007-8 represents the active equivalent part within the same DRD series, maintaining all functional specifications while providing current product support and regulatory compliance.

Q: Does the 1-1825007-8 meet current regulatory requirements?

A: Yes. The 1-1825007-8 is ROHS3 compliant, meeting current environmental and material restriction directives. The DRD16SE is RoHS non-compliant. For applications subject to RoHS requirements, the 1-1825007-8 is the appropriate selection.

Q: Are the mechanical and electrical life ratings identical?

A: Yes. Both the DRD16SE and 1-1825007-8 are rated for 10,000 steps of mechanical life and 10,000 steps of electrical life, ensuring equivalent operational durability and reliability.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both parts feature identical surface mount gull wing termination, 0.100" (2.54mm) pitch, and 0.291" (7.39mm) height above board. PCB footprints and assembly processes require no modification for substitution.
