Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HCS101T/SN is determined by the following parameters:

Critical Matching Parameters:

• Manufacturer: Microchip Technology
• Base Product Number: HCS101
• Type: Fixed Code Encoder
• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• Applications: Remote Control

Compliance Parameters:

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

The HCS101/SN qualifies as a direct substitute because it maintains identical electrical function, mechanical packaging, mounting configuration, and regulatory compliance specifications. The primary distinction is product status: HCS101T/SN is obsolete, while HCS101/SN is active and available.

Parameter Comparison

Engineering Selection Recommendations

HCS101/SN is the appropriate substitute for HCS101T/SN based on the following factors:

1. Product Status: HCS101/SN maintains active product status with current manufacturing support, whereas HCS101T/SN is obsolete and no longer produced.

2. Regulatory Compliance: Both parts maintain identical ROHS3 compliance, REACH unaffected status, and MSL rating, ensuring equivalent environmental and regulatory qualification.

3. Functional Equivalence: Both parts share identical base product number (HCS101), type classification (Fixed Code Encoder), and application domain (Remote Control).

4. Mechanical Compatibility: Identical 8-SOIC package dimensions (0.154", 3.90mm Width) and surface mount configuration ensure direct PCB layout compatibility without redesign.

5. Supply Availability: HCS101/SN is available in production quantities (2200 Pcs New Original In Stock), providing reliable supply chain access compared to the obsolete HCS101T/SN variant.

Frequently Asked Questions (FAQ)

Q: Can HCS101/SN be used as a direct replacement for HCS101T/SN in existing designs?

A: Yes. HCS101/SN is a direct substitute. Both parts share identical electrical specifications, package configuration, and mounting type. No circuit modifications or PCB redesign is required.

Q: Are there any differences in regulatory compliance between HCS101T/SN and HCS101/SN?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited). Regulatory qualification is equivalent.

Q: What is the primary reason for substitution?

A: HCS101T/SN has reached obsolete status and is no longer manufactured. HCS101/SN is the active equivalent part from Microchip Technology, ensuring continued availability and manufacturing support.
