BD48L30G-TL Equivalent & Substitute Parts

Part Overview

The BD48L30G-TL is a voltage supervisor IC from Rohm Semiconductor's BD48Lxx series, designed for single-channel voltage monitoring applications. This component functions as a voltage detector with open drain or open collector output, providing active low reset functionality. The BD48L30G-TL is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and production continuity. Equivalent and substitute parts maintain the core supervisory function while offering improved availability and product status.

Engineering Selection Recommendations

BD48K30G-TL (Parametric Equivalent): This part is the preferred direct replacement for the BD48L30G-TL. It maintains identical electrical specifications, the same 3-SSOP package footprint, and equivalent moisture sensitivity characteristics. The primary advantage is active product status with confirmed availability. This substitute requires no circuit redesign and provides pin-for-pin compatibility.

BD48E30G-TR (Manufacturer-Recommended Substitute): This part offers equivalent electrical performance with improved moisture sensitivity (MSL 1 versus MSL 3), eliminating moisture-related handling constraints. The 5-SSOP package requires PCB layout modification compared to the 3-SSOP footprint. This substitute is suitable for applications where PCB redesign is acceptable and enhanced moisture performance is beneficial. Both substitute parts maintain ROHS3 compliance and REACH unaffected status.

Frequently Asked Questions (FAQ)

Q: Can BD48K30G-TL be used as a direct replacement for BD48L30G-TL? A: Yes. The BD48K30G-TL is a parametric equivalent with identical electrical specifications, the same 3-SSOP package, and equivalent moisture sensitivity. No circuit modifications are required.

Q: What is the primary difference between BD48K30G-TL and BD48E30G-TR? A: The BD48K30G-TL maintains the 3-SSOP package footprint identical to the original part. The BD48E30G-TR uses a 5-SSOP package and offers improved moisture sensitivity (MSL 1 versus MSL 3). Package selection depends on PCB layout constraints and moisture handling requirements.

Q: Are all substitute parts RoHS compliant? A: Yes. Both BD48K30G-TL and BD48E30G-TR are ROHS3 compliant and REACH unaffected, matching the compliance status of the original BD48L30G-TL.

Q: Does the 5-SSOP package of BD48E30G-TR affect circuit functionality? A: No. The 5-SSOP package does not affect electrical functionality. However, PCB layout modifications are necessary to accommodate the different package footprint.

Q: What does MSL 1 (Unlimited) mean for BD48E30G-TR? A: MSL 1 indicates unlimited shelf life without moisture baking requirements. This contrasts with MSL 3 (168 Hours), which requires moisture baking before soldering. MSL 1 simplifies component handling and storage procedures.

Q: Are there packaging format differences between these parts? A: BD48L30G-TL and BD48K30G-TL are supplied in Cut Tape (CT) and Digi-Reel® formats. BD48E30G-TR is supplied in Tape & Reel (TR) format. Packaging format does not affect component functionality.
