DRM16CRA Equivalent & Substitute Parts

Part Overview

The DRM16CRA is a hexadecimal complement rotary DIP switch manufactured by TE Connectivity ALCOSWITCH Switches. This 16-position through-hole component features a rotary shaft actuator and is rated for 0.4VA at 20VAC/DC operation. The part is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain identical electrical ratings, mechanical dimensions, and functional characteristics to ensure direct replacement capability.

Substitute Part Grouping Explanation

Substitution of the DRM16CRA is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Current rating (0.4VA), voltage rating (20VAC/DC), and circuit configuration (hexadecimal complement) must be identical.

Mechanical Compatibility: Number of positions (16), actuator type (rotary with shaft), mounting configuration (through hole, right angle), pitch spacing (0.100"), and height above board (0.413") must match exactly.

Environmental Specifications: Operating temperature range (-30°C to 85°C), mechanical life (20,000 steps), and electrical life (20,000 steps) must be maintained.

Contact and Termination: Copper alloy contact material with gold finish and PC pin termination style must be preserved.

The substitute part 1825008-7 meets all these criteria and is classified as active product status, making it a direct functional equivalent for the obsolete DRM16CRA.

Engineering Selection Recommendations

The DRM16CRA is obsolete and no longer available from the manufacturer. The substitute part 1825008-7 is the direct equivalent, manufactured by the same supplier (TE Connectivity ALCOSWITCH Switches) within the same DR series. All electrical, mechanical, and dimensional specifications are identical between the two components.

The 1825008-7 is classified as active product status, ensuring availability for procurement and ongoing supply chain support. Both parts carry identical export classification (EAR99) and tariff codes (8536.50.9065), simplifying regulatory and logistics documentation.

For applications currently using the DRM16CRA, direct substitution with 1825008-7 requires no circuit modifications, PCB layout changes, or firmware adjustments. The components are pin-compatible and functionally equivalent across all specified parameters.

Frequently Asked Questions (FAQ)

Q: Can the 1825008-7 be used as a direct replacement for the DRM16CRA without PCB modifications?

A: Yes. The 1825008-7 is dimensionally and electrically identical to the DRM16CRA. Both components share the same pitch (0.100"), height above board (0.413"), mounting type (through hole, right angle), and termination style (PC pin). No PCB layout changes are required.

Q: What is the primary reason for substituting the DRM16CRA?

A: The DRM16CRA is classified as obsolete. The 1825008-7 is the active equivalent from TE Connectivity ALCOSWITCH Switches and is the recommended component for new designs and production continuity.

Q: Are the electrical ratings identical between these two parts?

A: Yes. Both the DRM16CRA and 1825008-7 are rated for 0.4VA at 20VAC/DC with a 16-position hexadecimal complement circuit configuration. Operating temperature range, mechanical life, and electrical life specifications are identical.

Q: What is the base product number for the 1825008-7?

A: The base product number is 1825008. The suffix "-7" indicates a specific variant within this product family.

Q: Are there any compliance or certification differences between the two parts?

A: Both parts share identical export classification (EAR99) and tariff codes (8536.50.9065). The DRM16CRA is RoHS non-compliant, while the 1825008-7 has RoHS status listed as not applicable. Both are REACH unaffected or vendor undefined, respectively.
