Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCS320T-I/SN is determined by the following critical parameters:

Functional Equivalence: Both the main part and substitute must be Code Hopping Encoder devices within the KEELOQ® series from Microchip Technology.

Package Compatibility: The 8-SOIC (0.154", 3.90mm Width) surface mount package must be identical to ensure PCB layout and assembly process compatibility.

Compliance Requirements: Both parts must maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 rating to satisfy regulatory and environmental requirements.

Application Suitability: The substitute part must support Remote Secure Access and Keyless Entry applications without functional degradation.

The HCS320-I/SN meets all substitution criteria and is classified as a direct manufacturer equivalent with active product status.

Parameter Comparison

Engineering Selection Recommendations

The HCS320-I/SN is the direct substitute for the obsolete HCS320T-I/SN. Both parts share identical electrical specifications, package geometry, and compliance certifications. The primary distinction is product status: HCS320-I/SN maintains active manufacturing status with confirmed inventory availability (2595 Pcs), whereas HCS320T-I/SN is obsolete.

Selection of HCS320-I/SN is appropriate for new designs, production continuity, and component replenishment. The active product status ensures long-term supply chain reliability and continued manufacturer support. Both parts satisfy ROHS3 and REACH compliance requirements for regulated markets.

Frequently Asked Questions (FAQ)

Q: Can HCS320-I/SN be used as a direct replacement for HCS320T-I/SN in existing designs?

A: Yes. Both parts are identical Code Hopping Encoder devices in the 8-SOIC package with matching electrical and mechanical specifications. No design modifications are required.

Q: What is the difference between HCS320T-I/SN and HCS320-I/SN?

A: The primary difference is product status. HCS320T-I/SN is obsolete, while HCS320-I/SN is active. The packaging format differs (unspecified versus Tube), but functional and electrical parameters are equivalent.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts maintain identical ROHS3 compliance, REACH Unaffected status, and MSL 1 rating. They satisfy the same regulatory requirements for secure access and keyless entry applications.

Q: Why should I transition from HCS320T-I/SN to HCS320-I/SN?

A: The HCS320T-I/SN is obsolete and subject to discontinuation. HCS320-I/SN is actively manufactured with confirmed inventory, ensuring supply chain continuity and long-term availability for production requirements.

Q: Is the 8-SOIC package identical between both parts?

A: Yes. Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. PCB layouts and assembly processes are fully compatible.
