DNLS160V-7 Equivalent & Substitute Parts

Part Overview

The DNLS160V-7 is an NPN bipolar junction transistor manufactured by Diodes Incorporated, designed for surface mount applications in the SOT-563 package. This component operates at 60 V collector-emitter breakdown voltage with a maximum collector current of 1 A and 300 mW power dissipation. The device is classified as obsolete, necessitating identification of active equivalent parts for new production and ongoing support applications. Substitute parts must maintain electrical compatibility across critical parameters including voltage rating, current capacity, and thermal characteristics while accommodating modern supply chain availability.

Current - Collector (Ic) (Max): Minimum 1 A or 900 mA with application verification
Package / Case: SOT-563 or SOT-666 compatible
Mounting Type: Surface Mount
Operating Temperature Range: Minimum -55°C to 150°C coverage
RoHS Status: ROHS3 Compliant

Secondary Compatibility Parameters:

Engineering Selection Recommendations

DSS4160V-7 (Diodes Incorporated)

The DSS4160V-7 is the primary recommended substitute for the obsolete DNLS160V-7. Both parts are manufactured by Diodes Incorporated and share identical electrical specifications across all critical parameters: 60 V breakdown voltage, 1 A maximum collector current, 150 MHz transition frequency, and -55°C to 150°C operating range. The DSS4160V-7 is classified as Active product status, ensuring long-term supply availability. The increased power rating (600 mW vs. 300 mW) provides additional thermal margin without affecting circuit compatibility. Both parts are ROHS3 compliant and REACH unaffected. The DSS4160V-7 is supplied in Cut Tape and Digi-Reel packaging with 125,100 units in stock.

CMLT3820G TR PBFREE (Central Semiconductor Corp)

The CMLT3820G TR PBFREE is an active substitute manufactured by Central Semiconductor Corp. This part maintains the 60 V breakdown voltage and 1 A collector current specifications. The operating temperature range extends to -65°C, providing enhanced low-temperature performance. The transition frequency and DC current gain specifications are equivalent. The power rating is 250 mW, which is lower than the original 300 mW specification; this part is suitable for applications where thermal dissipation is not a limiting factor. ROHS3 compliance and REACH unaffected status are maintained. Supplied in Tape & Reel packaging with 12,870 units in stock.

PBSS4160V,115 (Nexperia USA Inc.)

The PBSS4160V,115 is classified as Not For New Designs and is not recommended for new production applications. While this part maintains the 60 V breakdown voltage and equivalent saturation characteristics, the maximum collector current is reduced to 900 mA, representing a 10% reduction from the original 1 A specification. The transition frequency is elevated to 220 MHz. The operating temperature specification is incomplete (150°C maximum only, without minimum temperature). This part is supplied in SOT-666 package, which differs from the original SOT-563. Use of this part is restricted to legacy system maintenance where existing designs have been validated with this component.

Frequently Asked Questions (FAQ)

Q: Can the DSS4160V-7 be used as a direct replacement for the DNLS160V-7 in all applications?

A: Yes. The DSS4160V-7 meets or exceeds all electrical specifications of the DNLS160V-7. Both parts share identical voltage ratings (60 V), current capacity (1 A), transition frequency (150 MHz), operating temperature range (-55°C to 150°C), and package type (SOT-563). The increased power rating of the DSS4160V-7 (600 mW vs. 300 mW) provides additional thermal capability without introducing compatibility issues.

Q: What is the difference between SOT-563 and SOT-666 packages?

A: SOT-563 and SOT-666 are both surface mount packages for small-signal transistors. The PBSS4160V,115 is supplied in SOT-666 package, while the DNLS160V-7, DSS4160V-7, and CMLT3820G are supplied in SOT-563 package. Physical dimensions and pin configurations differ between these packages. PCB layout and footprint designs must be verified before substituting parts with different package types.

Q: Is the CMLT3820G TR PBFREE suitable for applications requiring the full 300 mW power dissipation?

A: The CMLT3820G TR PBFREE has a maximum power rating of 250 mW, which is 50 mW lower than the original DNLS160V-7 specification of 300 mW. This part is suitable for applications where actual power dissipation remains below 250 mW. Applications requiring sustained operation at or near 300 mW should use the DSS4160V-7 (600 mW rating) to ensure adequate thermal margin.

Q: Why is the PBSS4160V,115 marked as Not For New Designs?

A: The PBSS4160V,115 is classified as Not For New Designs by the manufacturer, indicating that this part is in end-of-life status and is not recommended for incorporation into new product designs. While this part may be used for legacy system support and maintenance, new designs should utilize active parts such as the DSS4160V-7 or CMLT3820G TR PBFREE to ensure long-term supply availability and manufacturer support.

Q: What is the significance of the DC Current Gain (hFE) difference between the DNLS160V-7 and substitute parts?

A: The DNLS160V-7 specifies a minimum DC Current Gain of 250 @ 1mA, 5V, while substitute parts specify 200 @ 500mA, 5V. These measurements are taken at different operating points. The substitute parts maintain sufficient current gain for typical switching and amplification applications. Circuit designs should verify that the specified gain at the actual operating current and voltage is adequate for the intended application.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The DSS4160V-7, CMLT3820G TR PBFREE, and PBSS4160V,115 are all ROHS3 compliant and REACH unaffected, matching the compliance status of the original DNLS160V-7. All parts are suitable for applications requiring RoHS compliance.

Q: What is the Moisture Sensitivity Level (MSL) for these parts?

A: All parts, including the DNLS160V-7 and all substitute parts, have an MSL rating of 1 (Unlimited). This indicates that these components have unlimited shelf life and do not require special moisture control during storage or handling.
