HCS201T-I/SN Code Hopping Encoder Equivalent & Substitute Parts

Part Overview

The HCS201T-I/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 product status with full RoHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when packaging format, inventory availability, or supply chain requirements necessitate alternative sourcing while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCS201T-I/SN is determined by strict adherence to the following parameters:

Critical Matching Parameters:

• Manufacturer: Microchip Technology
• Base Product Number: HCS201
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Supplier Device Package: 8-SOIC
• Mounting Type: Surface Mount
• Series: KEELOQ®
• Type: Code Hopping Encoder

Compliance Parameters:

• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected
• Product Status: Active

The primary distinction between the main part and substitute parts is the packaging format (Tape & Reel versus Tube). Both formats contain identical die and electrical specifications. The substitution is valid when all electrical, mechanical, and compliance parameters remain unchanged.

Parameter Comparison

Engineering Selection Recommendations

Both HCS201T-I/SN and HCS201-I/SN are active products from Microchip Technology with identical electrical specifications and full regulatory compliance. Selection between these parts is determined by packaging and supply chain requirements:

HCS201T-I/SN (Tape & Reel): Suitable for high-volume automated assembly operations where continuous reel feeding is standard. Tape & Reel packaging optimizes pick-and-place machine compatibility and reduces component handling.

HCS201-I/SN (Tube): Suitable for lower-volume production, manual assembly, or applications where tube packaging is preferred for component storage and handling. Tube packaging provides 18,374 pieces in current inventory.

Both parts maintain ROHS3 compliance, unlimited moisture sensitivity rating, and active product status. No electrical or mechanical redesign is required when substituting between these packaging formats.

Frequently Asked Questions (FAQ)

Q: Can HCS201-I/SN replace HCS201T-I/SN in production?

A: Yes. Both parts are identical Code Hopping Encoders in 8-SOIC packages with matching electrical specifications, RoHS3 compliance, and active product status. The only difference is packaging format (Tube versus Tape & Reel).

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

A: Tape & Reel packaging supplies components on continuous reels suitable for automated pick-and-place assembly. Tube packaging supplies components in cylindrical containers suitable for manual handling and lower-volume assembly. Both contain the same die and electrical specifications.

Q: Are there any PCB layout or assembly differences between these parts?

A: No. Both parts use identical 8-SOIC (0.154", 3.90mm Width) packages. PCB footprints, solder pad dimensions, and assembly procedures are identical.

Q: Do both parts meet the same compliance standards?

A: Yes. Both HCS201T-I/SN and HCS201-I/SN are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs. Selection depends on manufacturing volume and assembly equipment. High-volume automated assembly typically uses Tape & Reel format. Lower-volume or manual assembly typically uses Tube format.

Q: Is there a performance difference between the two packaging formats?

A: No. Packaging format does not affect electrical performance, functionality, or reliability. Both parts deliver identical Code Hopping Encoder performance for Remote Secure Access and Keyless Entry applications.
