Key Parameters

Substitute Part Grouping Explanation

Substitution of the HCS500T-I/SM is determined by strict alignment of the following parameters:

Critical Substitution Parameters:

• Manufacturer: Microchip Technology
• Series: KEELOQ®
• Type: Code Hopping Decoder
• Package / Case: 8-SOIC (0.209", 5.30mm Width)
• Supplier Device Package: 8-SOIJ
• Mounting Type: Surface Mount
• Applications: Remote Secure Access, Keyless Entry
• Moisture Sensitivity Level: 1 (Unlimited)
• REACH Status: REACH Unaffected

The HCS500T-I/SM shares all critical parameters with the HCS500-I/SM. Both devices are manufactured by Microchip Technology within the KEELOQ® series, employ identical package specifications (8-SOIC, 8-SOIJ), and support the same applications. The primary distinction is product status: HCS500T-I/SM is obsolete, while HCS500-I/SM is active.

Parameter Comparison

Engineering Selection Recommendations

HCS500-I/SM as Direct Substitute:

The HCS500-I/SM is the direct substitute for the obsolete HCS500T-I/SM. Both parts maintain identical electrical and mechanical specifications, including package type, mounting configuration, and application suitability. The HCS500-I/SM is currently in active production status with confirmed inventory availability (1827 Pcs New Original In Stock).

Compliance Considerations:

The HCS500-I/SM carries ROHS3 compliance certification, whereas the HCS500T-I/SM is RoHS non-compliant. For new designs or systems requiring regulatory compliance with RoHS3 standards, the HCS500-I/SM is the appropriate selection. Both parts maintain REACH Unaffected status and identical MSL ratings.

Supply Chain Status:

The HCS500T-I/SM is obsolete with limited remaining inventory (775 Pcs). The HCS500-I/SM is actively manufactured and stocked, providing long-term supply chain reliability for ongoing production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can HCS500-I/SM directly replace HCS500T-I/SM in existing designs?

A: Yes. Both parts are identical in electrical function, package type (8-SOIC), and mounting configuration (Surface Mount). No circuit modifications are required for substitution.

Q: What is the difference between HCS500T-I/SM and HCS500-I/SM?

A: The primary differences are product status (HCS500T-I/SM is obsolete; HCS500-I/SM is active) and RoHS compliance (HCS500T-I/SM is non-compliant; HCS500-I/SM is ROHS3 compliant). Functional and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use the 8-SOIC package with 0.209" width (5.30mm). The supplier device package designation is 8-SOIJ for both. No PCB layout modifications are necessary.

Q: Which part should be selected for new production?

A: The HCS500-I/SM should be selected for new production due to active manufacturing status, ROHS3 compliance, and confirmed supply availability.

Q: Is the HCS500-I/SM suitable for remote secure access and keyless entry applications?

A: Yes. The HCS500-I/SM is specified for both Remote Secure Access and Keyless Entry applications, identical to the HCS500T-I/SM.

Q: What is the moisture sensitivity level for both parts?

A: Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
