Key Parameters

Substitute Part Grouping Explanation

Substitute parts are grouped strictly based on the following parameters: device type, bidirectional channel count, reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, peak pulse power, mounting type, package/case, grade, qualification, RoHS status, and operating temperature. Only substitute parts matching these parameters precisely are considered equivalent for selection within the Transient Voltage Suppressors (TVS) category.

Parameter Comparison

Engineering Selection Recommendations

Selection of the substitute part is determined by product status, regulatory compliance, and qualification certifications. P6SMB12CAHM3_A/I is obsolete; P6SMB12CAHM3_B/I is active and maintains the same automotive grade, ROHS3 compliance, AEC-Q101 qualification, and identical technical parameters. The substitute part aligns with regulatory and certification requirements and supports continuity in design and sourcing within the TVS diode product category.

Frequently Asked Questions (FAQ)

Q1: What are the essential criteria for substituting P6SMB12CAHM3_A/I?
A1: The substitute must match type, bidirectional channel count, reverse standoff voltage, breakdown voltage, clamping voltage, peak pulse current, peak pulse power, mounting type, package/case, grade, qualification, operating temperature, and compliance credentials.

Q2: Is physical compatibility ensured when substituting with P6SMB12CAHM3_B/I?
A2: Both components use the DO-214AA (SMB) package for surface mount applications, ensuring full mechanical compatibility.

Q3: Are the electrical characteristics identical between the main and substitute part?
A3: Every key electrical parameter, including voltages, peak pulse current, and power ratings, is identical between P6SMB12CAHM3_A/I and P6SMB12CAHM3_B/I.

Q4: Is there any difference in qualification or compliance status?
A4: Both parts hold AEC-Q101 automotive qualification and ROHS3 compliance.

Q5: Why is substitution necessary for this TVS diode?
A5: P6SMB12CAHM3_A/I is obsolete; continuing designs or procurement require the use of active substitutes with matching parameters for performance and certification retention.
