HCS200T/SN Code Hopping Encoder Equivalent & Substitute Parts

Part Overview

The HCS200T/SN is a Code Hopping Encoder manufactured by Microchip Technology, part of the KEELOQ® series. This integrated circuit functions as an 8-SOIC surface mount encoder designed for secure remote access and keyless entry applications. The device is currently in active production status with verified programmability through DiGi-Electronics.

Substitute parts are identified when equivalent electrical specifications, functional performance, and mechanical compatibility are maintained across different packaging or distribution formats. The HCS200T/SN operates in Cut Tape packaging; alternative sourcing may be required due to inventory availability, supply chain considerations, or specific packaging requirements for manufacturing processes.

Substitute Part Grouping Explanation

Substitution eligibility for the HCS200T/SN is determined by the following criteria:

Electrical & Functional Equivalence: The substitute part must belong to the same KEELOQ® series and maintain identical Code Hopping Encoder functionality for Remote Secure Access and Keyless Entry applications.

Package Compatibility: The substitute part must use the 8-SOIC (0.154", 3.90mm Width) package format, ensuring mechanical and electrical pin compatibility with existing PCB designs and assembly processes.

Compliance & Certification: Both the main part and substitute must maintain ROHS3 compliance and REACH Unaffected status, with identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications.

Manufacturer & Series Consistency: The substitute part must be manufactured by Microchip Technology and belong to the KEELOQ® series to ensure consistent performance characteristics and design specifications.

Product Status: The substitute part must maintain Active product status to ensure ongoing availability and manufacturer support.

The primary difference between the HCS200T/SN and its substitute lies in packaging format (Cut Tape versus Tube) and moisture sensitivity level specifications, which do not affect functional performance or electrical characteristics.

Engineering Selection Recommendations

HCS200T/SN (Cut Tape Packaging): Select this configuration when automated pick-and-place assembly processes require continuous reel feeding. Cut Tape packaging provides MSL Level 1 (Unlimited moisture sensitivity), eliminating bake-out requirements prior to reflow soldering. This format is optimal for high-volume production environments with controlled manufacturing conditions.

HCS200/SN (Tube Packaging): Select this configuration for lower-volume production runs, manual assembly operations, or when inventory management favors smaller quantity units. Tube packaging maintains MSL Level 3 (168 Hours), requiring standard moisture control procedures during storage and handling. This format is suitable for prototyping, repair, and maintenance applications.

Both configurations maintain identical electrical performance, functional specifications, and compliance certifications. Selection between HCS200T/SN and HCS200/SN is determined solely by manufacturing process requirements and packaging logistics, not by technical performance differences.

Frequently Asked Questions (FAQ)

Q: Are HCS200T/SN and HCS200/SN electrically identical?

A: Yes. Both parts are Code Hopping Encoders from the KEELOQ® series manufactured by Microchip Technology. They share identical electrical specifications, pin configurations, and functional performance for Remote Secure Access and Keyless Entry applications.

Q: What is the difference between Cut Tape and Tube packaging?

A: Cut Tape (CT) packaging supplies components on a continuous reel suitable for automated assembly equipment. Tube packaging supplies components in individual plastic tubes, typically used for manual assembly or lower-volume applications. Both formats contain the same component with identical electrical characteristics.

Q: Can I substitute HCS200/SN for HCS200T/SN in my PCB design?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pin assignments and electrical specifications. PCB footprints and design files require no modification.

Q: What does MSL Level 1 versus MSL Level 3 mean?

A: MSL (Moisture Sensitivity Level) indicates the component's sensitivity to moisture during storage and handling. MSL Level 1 (Unlimited) requires no special moisture control. MSL Level 3 (168 Hours) requires the component to be used within 168 hours of package opening under controlled humidity conditions. Standard industry practice includes bake-out procedures for MSL Level 3 components if storage time exceeds specified limits.

Q: Are both parts ROHS3 compliant?

A: Yes. Both HCS200T/SN and HCS200/SN are ROHS3 compliant and REACH Unaffected, meeting all applicable environmental and regulatory requirements.

Q: Which part should I specify for high-volume automated assembly?

A: HCS200T/SN in Cut Tape packaging is optimized for automated pick-and-place assembly with continuous reel feeding. MSL Level 1 eliminates moisture management complexity in high-speed production environments.

Q: Which part is better for prototyping or small-quantity builds?

A: HCS200/SN in Tube packaging is suitable for prototyping and small-quantity applications. Tube format allows flexible quantity selection and simplified inventory management for development projects.
