DRD10RA Equivalent & Substitute Parts

Part Overview

The DRD10RA is a rotary DIP switch manufactured by TE Connectivity ALCOSWITCH Switches, configured for BCD (Binary Coded Decimal) applications with 10 positions. This through-hole, right-angle mounted switch is rated for 0.4VA at 20VAC/DC and features a tool-actuated rotary mechanism with flush, recessed actuation. The DRD10RA is classified as obsolete, making identification of equivalent substitute components necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DRD10RA 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 (BCD), number of positions (10), current rating (0.4VA), and voltage rating (20VAC/DC) must be identical to ensure functional compatibility within the circuit.

Mechanical Parameters: Actuator type (rotary for tool), actuator level (flush, recessed), mounting type (through hole, right angle), termination style (PC pin), and pitch (0.100" / 2.54mm) must match to ensure physical compatibility with the PCB layout and mechanical assembly.

Material and Environmental Parameters: Contact material (copper alloy), contact finish (gold), body material (polyphenylene sulfide), and operating temperature range (-30°C ~ 85°C) must be consistent to maintain electrical performance and environmental reliability.

The substitute part 1825008-2 meets all these criteria and is therefore a direct functional and mechanical equivalent to the DRD10RA.

Parameter Comparison

Engineering Selection Recommendations

The DRD10RA is classified as obsolete, which necessitates transition to an active equivalent part for new designs and ongoing production support. The substitute part 1825008-2 is functionally and mechanically identical across all critical parameters and carries an active product status with ROHS3 compliance certification.

Selection of 1825008-2 is appropriate for applications requiring direct replacement of the DRD10RA. The substitute part maintains full electrical and mechanical compatibility while offering the advantage of active manufacturer support and compliance with current regulatory standards. The ROHS3 compliance of 1825008-2 aligns with modern environmental and regulatory requirements, whereas the DRD10RA's obsolete status limits its availability and support.

Both parts are manufactured by TE Connectivity ALCOSWITCH Switches and share identical electrical ratings, mechanical configurations, and environmental specifications. The transition from DRD10RA to 1825008-2 requires no circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can 1825008-2 be used as a direct replacement for DRD10RA in existing designs?

A: Yes. The 1825008-2 is electrically and mechanically equivalent to the DRD10RA. All critical parameters including circuit configuration, position count, voltage and current ratings, mounting type, pitch, and physical dimensions are identical. No circuit or PCB modifications are required.

Q: What is the primary difference between DRD10RA and 1825008-2?

A: The DRD10RA is obsolete, while 1825008-2 is active. Additionally, 1825008-2 is ROHS3 compliant and washable, whereas the DRD10RA is not washable. The electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Yes. The DRD10RA is supplied in standard packaging, while 1825008-2 is supplied in tube packaging. This difference does not affect electrical or mechanical compatibility; it only impacts handling and storage logistics.

Q: Does the washable feature of 1825008-2 affect compatibility?

A: No. The washable feature of 1825008-2 is an additional capability that does not impact electrical or mechanical compatibility with the DRD10RA. It provides enhanced manufacturing flexibility for applications requiring post-assembly cleaning.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both the DRD10RA and 1825008-2 operate across the identical temperature range of -30°C to 85°C.

Q: What is the inventory status of these parts?

A: The DRD10RA has 1,172 pieces in stock. The 1825008-2 has 1,895 pieces in stock. Given the obsolete status of the DRD10RA, 1825008-2 is the recommended choice for new procurement.
