HCS500/SM Code Hopping Decoder Equivalent & Substitute Parts

Part Overview

The HCS500/SM is an integrated circuit code hopping decoder manufactured by Microchip Technology, designed for secure remote access and keyless entry applications. This surface-mount device operates within the KEELOQ® series and is currently in active product status. The HCS500/SM is ROHS3 compliant and carries an unlimited moisture sensitivity level rating, making it suitable for standard manufacturing and storage conditions.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable due to inventory constraints, supply chain disruptions, or manufacturing discontinuation. Substitute parts must maintain identical electrical characteristics, mechanical compatibility, and functional performance to ensure seamless integration into existing designs without requiring circuit modifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HCS500/SM are determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Identical manufacturer (Microchip Technology)
• Identical series designation (KEELOQ®)
• Identical functional type (Code Hopping Decoder)
• Identical package specification (8-SOIC, 0.209" width, 5.30mm)
• Identical supplier device package (8-SOIJ)
• Identical mounting technology (Surface Mount)
• Identical or superior RoHS compliance status
• Identical or superior moisture sensitivity rating

The HCS500-I/SM qualifies as a direct substitute based on complete alignment with all specified parameters. Both parts share the same base product number (HCS500), manufacturer, series, package dimensions, and compliance certifications. The suffix variation (-I) indicates a temperature or performance grade specification that does not affect mechanical or electrical compatibility within the defined application scope.

Engineering Selection Recommendations

HCS500-I/SM Selection Basis:

The HCS500-I/SM is a valid substitute for the HCS500/SM based on the following engineering criteria:

1. Compliance Alignment: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory requirements are met in all target markets.

2. Active Product Status: Both parts are designated as active products by Microchip Technology, confirming ongoing manufacturing support and supply chain availability.

3. Identical Mechanical Specifications: The 8-SOIC package with 0.209" width and 5.30mm dimensions ensures direct PCB footprint compatibility without layout modifications.

4. Functional Equivalence: Both parts operate within the KEELOQ® series as code hopping decoders, maintaining identical signal processing and security protocol implementation for remote secure access and keyless entry applications.

5. Manufacturing Certifications: Identical moisture sensitivity level (MSL 1) and supplier device package designation (8-SOIJ) confirm equivalent handling, storage, and assembly requirements.

Selection between HCS500/SM and HCS500-I/SM should be based on inventory availability and delivery timeline requirements, as both parts provide equivalent functional and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can HCS500-I/SM be used as a direct replacement for HCS500/SM without PCB modifications?

A: Yes. Both parts share identical package dimensions (8-SOIC, 0.209" width, 5.30mm), identical pin configurations, and identical mounting specifications. No PCB layout changes are required.

Q: What does the "-I" suffix in HCS500-I/SM indicate?

A: The "-I" suffix designates a specific temperature or performance grade variant within the HCS500 base product family. This suffix does not affect mechanical compatibility or functional performance within the specified application scope.

Q: Are both parts subject to the same handling and storage requirements?

A: Yes. Both HCS500/SM and HCS500-I/SM carry identical Moisture Sensitivity Level (MSL) ratings of 1 (Unlimited), indicating equivalent handling, storage, and assembly requirements with no special moisture control measures required.

Q: Do both parts comply with current environmental regulations?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components in target markets.

Q: What is the primary reason to consider HCS500-I/SM as a substitute?

A: The HCS500-I/SM should be considered when HCS500/SM inventory is unavailable or when supply chain delays impact project timelines. Both parts provide identical electrical and mechanical performance for remote secure access and keyless entry applications.

Q: Are there any application-specific limitations when substituting between these parts?

A: No. Both parts are designated for identical applications (Remote Secure Access, Keyless Entry) and operate within the same KEELOQ® series, ensuring equivalent functional performance across all specified use cases.
