Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 101020057 are identified based on strict parameter alignment across the following criteria:

Primary Substitution Criteria:

• Sensor Type: Fingerprint
• Output Type: Serial
• Operating Temperature Range: 20°C ~ 50°C (TA)
• RoHS Compliance Status
• Moisture Sensitivity Level (MSL): 1 (Unlimited)
• ECCN Classification: 3A981
• HTSUS Code: 8473.30.1180

Parts meeting all specified parameters are classified as direct equivalents. The substitute part Adafruit Industries LLC model 751 satisfies these core electrical and mechanical parameters, establishing functional interchangeability for serial fingerprint sensing applications.

Parameter Comparison

Engineering Selection Recommendations

The Adafruit Industries LLC model 751 fingerprint sensor provides direct parameter equivalence to the obsolete Seeed 101020057. Both components share identical sensor type, serial output interface, operating temperature specifications, and regulatory classifications (ECCN 3A981, HTSUS 8473.30.1180).

The primary distinction is product status: the 101020057 is obsolete while the 751 maintains active production status. This status difference ensures ongoing availability and supply chain continuity for the 751 substitute. Both components maintain equivalent RoHS compliance postures (RoHS Compliant versus ROHS3 Compliant) and identical moisture sensitivity ratings.

Selection of the 751 as a substitute is supported by complete parameter alignment across all specified electrical and mechanical criteria. The active product status of the 751 provides additional assurance for long-term procurement reliability.

Frequently Asked Questions (FAQ)

Q: What makes the Adafruit 751 a valid substitute for the Seeed 101020057?

A: Both components share identical fingerprint sensor type, serial output interface, 20°C to 50°C operating temperature range, MSL rating of 1 (Unlimited), and regulatory classifications (ECCN 3A981, HTSUS 8473.30.1180). These parameters define functional interchangeability for serial fingerprint sensing applications.

Q: Does the difference in RoHS status (RoHS Compliant versus ROHS3 Compliant) affect substitution?

A: No. Both designations indicate RoHS compliance. ROHS3 represents a more recent compliance standard iteration. Both parts meet RoHS requirements and are substitutable from a regulatory standpoint.

Q: Why is the 101020057 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Seeed Technology Co., Ltd. The 751 substitute maintains active production status, ensuring continued availability for new designs and replacement procurement.

Q: Are there packaging considerations when substituting the 751 for the 101020057?

A: The 101020057 packaging is not specified in available documentation. The 751 is supplied in bulk packaging. Verify packaging requirements for your specific application and procurement process.

Q: Can the 751 operate outside the 20°C to 50°C temperature range?

A: The specified operating temperature range for the 751 is 20°C to 50°C (TA), matching the 101020057. Applications requiring operation outside this range require alternative component evaluation.
