BC846SHF Equivalent & Substitute Parts

Part Overview

The BC846SHF is a dual NPN bipolar junction transistor (BJT) array manufactured by Nexperia USA Inc., designed for general-purpose switching and amplification applications. The device integrates two independent NPN transistors in a compact 6-TSSOP surface mount package, offering a maximum collector current of 100mA, collector-emitter breakdown voltage of 65V, and transition frequency of 100MHz.

The BC846SHF is classified as obsolete. Identification of equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications currently utilizing this component.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the BC846SHF is determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish the substitution criteria:

Electrical Parameters (Must Match):

• Transistor configuration: 2 NPN (Dual)
• Maximum collector current (Ic): 100mA
• Collector-emitter breakdown voltage: 65V
• Vce saturation characteristics: 300mV @ 5mA, 100mA
• Collector cutoff current: 15nA (ICBO)
• DC current gain (hFE): 110 minimum @ 2mA, 5V
• Maximum power dissipation: 270mW
• Transition frequency: 100MHz
• Maximum operating temperature: 175°C

Mechanical Parameters (Must Match):

• Package type: 6-TSSOP (SC-88, SOT-363)
• Mounting type: Surface Mount

Compliance Parameters:

• RoHS3 compliance required
• Moisture sensitivity level: 3 (168 Hours)

Substitute parts must satisfy all electrical and mechanical parameters without deviation. Product status and supply availability are secondary considerations that inform selection priority but do not alter substitution eligibility.

Parameter Comparison

Engineering Selection Recommendations

The BC846SH-QF is the manufacturer-recommended substitute for the BC846SHF. Both components are manufactured by Nexperia USA Inc. and maintain identical electrical and mechanical specifications across all critical parameters.

Selection Basis:

The BC846SH-QF satisfies all substitution criteria established by parameter equivalence. The component is classified as Active product status, ensuring ongoing availability and supply chain support. The BC846SH-QF carries ROHS3 compliance and maintains the same moisture sensitivity level (MSL 3, 168 Hours) as the original part.

The BC846SH-QF includes additional certifications: AEC-Q101 automotive qualification and REACH compliance status (REACH Unaffected). These certifications do not alter the component's suitability for general-purpose applications but indicate expanded qualification scope.

Inventory availability of the BC846SH-QF (1112 pieces in stock) exceeds that of the BC846SHF (619 pieces), supporting immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the BC846SH-QF be used as a direct replacement for the BC846SHF in existing designs?

A: Yes. The BC846SH-QF is electrically and mechanically equivalent to the BC846SHF across all specified parameters. No circuit modifications or design changes are required. Both components share identical pin configuration, package dimensions, and electrical characteristics.

Q: What is the significance of the BC846SHF being classified as obsolete?

A: Obsolete status indicates that the manufacturer has discontinued production and support for the BC846SHF. The BC846SH-QF, classified as Active, represents the current production equivalent and is the appropriate selection for new designs and ongoing production support.

Q: Are there differences in the package designations between these parts?

A: Both the BC846SHF and BC846SH-QF utilize the 6-TSSOP package (also designated SC-88 or SOT-363). Package dimensions, pin spacing, and land pattern are identical. No PCB layout modifications are necessary.

Q: Does the AEC-Q101 qualification of the BC846SH-QF affect its use in non-automotive applications?

A: No. AEC-Q101 qualification indicates that the BC846SH-QF meets automotive industry reliability standards. This qualification does not restrict use in general-purpose or non-automotive applications. The component remains suitable for all applications previously supported by the BC846SHF.

Q: What is the moisture sensitivity level (MSL) and why is it important?

A: Moisture Sensitivity Level 3 (168 Hours) specifies the maximum time the component can be exposed to ambient conditions (30°C, 85% relative humidity) before requiring baking prior to soldering. Both the BC846SHF and BC846SH-QF share identical MSL specifications, ensuring equivalent handling and storage requirements.

Q: Are there any electrical performance differences between the BC846SHF and BC846SH-QF?

A: No. Both components maintain identical maximum ratings, saturation characteristics, current gain specifications, and frequency response. Electrical performance is equivalent across all specified parameters.
