DRW10CRA Equivalent & Substitute Parts

Part Overview

The DRW10CRA is a rotary DIP switch manufactured by TE Connectivity ALCOSWITCH Switches, configured as a 10-position BCD complement switch with through-hole, right-angle mounting. The device features a rotary knob actuator, gold-plated copper alloy contacts, and is rated for 0.4VA at 20VAC/DC operation across an operating temperature range of -30°C to 85°C.

The DRW10CRA is classified as obsolete. Identification of equivalent and substitute parts is necessary to support ongoing maintenance, repair, and new design requirements where this component is specified or currently deployed.

• Voltage rating: 20VAC/DC

Mechanical Parameters:

• Actuator type: Rotary with Knob
• Mounting type: Through Hole, Right Angle
• Contact material: Copper Alloy
• Contact finish: Gold
• Pitch: 0.100" (2.54mm), Full
• Height above board: 0.413" (10.50mm)
• Body material: Polyphenylene Sulfide (PPS)
• Termination style: PC Pin

Environmental Parameters:

• Operating temperature range: -30°C to 85°C
• Mechanical life: 20,000 Steps
• Electrical life: 20,000 Steps

Parts meeting all specified parameters are classified as direct equivalents and may be substituted without design modification.

Parameter Comparison

Engineering Selection Recommendations

The part 1-1825008-3 is a direct functional equivalent to the DRW10CRA across all specified electrical and mechanical parameters. The primary distinction is product status: the DRW10CRA is classified as obsolete, while 1-1825008-3 is active.

Selection of 1-1825008-3 is appropriate for applications requiring:

• Replacement of end-of-life DRW10CRA units in existing designs
• New designs requiring 10-position BCD complement rotary DIP switches with identical electrical and mechanical specifications
• Maintenance and repair scenarios where component availability is critical

Both parts share identical export classification (EAR99) and tariff codes (8536.50.9065), indicating equivalent regulatory treatment for procurement and logistics purposes.

Frequently Asked Questions (FAQ)

Q: Can 1-1825008-3 be used as a direct replacement for DRW10CRA in existing circuit boards?

A: Yes. The 1-1825008-3 is electrically and mechanically equivalent to the DRW10CRA. All parameters including mounting type, pitch, height above board, electrical ratings, and operating temperature range are identical. No circuit board modifications are required.

Q: What is the primary reason for substitution?
