Key Parameters

Substitute Part Grouping Explanation

Substitution of the MA3J142EGL is determined by electrical and mechanical parameter equivalence. The following criteria establish functional interchangeability:

Electrical Parameters (Critical):

• Diode configuration must be 1 Pair Common Cathode
• Maximum DC reverse voltage (Vr) must be 80 V or greater
• Average rectified current (Io) per diode must be 100 mA or greater
• Forward voltage (Vf) at 100 mA must not exceed 1.2 V
• Reverse recovery time (trr) must be 3 ns or less
• Reverse leakage current at 75 V must not exceed 100 nA
• Maximum junction operating temperature must be 150°C or higher
• Technology classification must be Standard
• Speed classification must be Small Signal ≤ 200 mA (Io), Any Speed

Mechanical Parameters (Required):

• Mounting type must be Surface Mount
• Moisture Sensitivity Level must be 1 (Unlimited)

Substitute parts meeting all electrical and mechanical parameters are functionally equivalent and may be used as direct replacements in circuit applications designed for the MA3J142EGL.

Parameter Comparison

Engineering Selection Recommendations

The M1MA142WKT1G manufactured by onsemi is an electrical equivalent to the MA3J142EGL. All critical electrical parameters—reverse voltage, forward voltage, current ratings, recovery time, leakage current, and temperature rating—are identical. Both devices employ Standard technology and meet the same speed classification for small-signal applications.

The M1MA142WKT1G holds Active product status, ensuring ongoing availability and manufacturing support. The device is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

The primary difference between the two parts is the package configuration: the MA3J142EGL uses SC-85 (SMini3-F2) while the M1MA142WKT1G uses SC-70 (SOT-323). Both are surface mount packages with identical moisture sensitivity levels. The SC-70 package is a standard industry format with widespread design tool support and manufacturing capability.

Selection of the M1MA142WKT1G as a substitute requires verification that the SC-70 package footprint is compatible with the target printed circuit board layout. If the original SC-85 footprint cannot be modified, alternative solutions must be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the M1MA142WKT1G directly replace the MA3J142EGL in all applications?

A: The M1MA142WKT1G is electrically equivalent to the MA3J142EGL across all specified parameters. However, the package footprint differs (SC-70 versus SC-85). Direct replacement requires that the printed circuit board layout accommodates the SC-70 package dimensions and pin configuration.

Q: What is the significance of the different package types (SC-85 versus SC-70)?

A: SC-85 and SC-70 are distinct surface mount package formats with different physical dimensions and land patterns. SC-70 is a smaller package (SOT-323 equivalent) compared to SC-85. PCB layout modifications are necessary if transitioning between these packages.

Q: Are the electrical characteristics identical between MA3J142EGL and M1MA142WKT1G?

A: Yes. Both devices share identical specifications for reverse voltage (80 V), forward voltage (1.2 V @ 100 mA), average rectified current (100 mA), reverse recovery time (3 ns), reverse leakage current (100 nA @ 75 V), and maximum junction temperature (150°C).

Q: Why is the MA3J142EGL classified as obsolete?

A: The MA3J142EGL is no longer manufactured by Panasonic Electronic Components. The obsolete status indicates that new production quantities are unavailable from the original manufacturer.

Q: Does the M1MA142WKT1G meet current compliance standards?

A: Yes. The M1MA142WKT1G is RoHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

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

A: Both the MA3J142EGL and M1MA142WKT1G have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are there any differences in the diode configuration between the two parts?

A: No. Both devices are configured as 1 Pair Common Cathode diode arrays with identical electrical characteristics.
