HIP6521CB Equivalent & Substitute Parts

Part Overview

The HIP6521CB is a Power Management Integrated Circuit (PMIC) manufactured by Renesas Electronics Corporation, functioning as a quad output voltage regulator combining synchronous buck and linear (LDO) topologies. This device integrates one step-down buck converter and three linear regulators in a 16-SOIC surface mount package, operating at a switching frequency of 300kHz with a supply voltage range of 4.75V to 5.25V.

The HIP6521CB is classified as obsolete. Locating equivalent or substitute components is necessary for system redesign, production continuation, or inventory replenishment when original stock becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the HIP6521CB is determined by strict equivalence across the following critical parameters:

• Topology configuration: Step-Down (Buck) Synchronous (1) combined with Linear (LDO) (3)
• Number of outputs: 4
• Switching frequency: 300kHz
• Supply voltage range: 4.75V ~ 5.25V
• Operating temperature range: 0°C ~ 70°C
• Package type: 16-SOIC with identical physical dimensions (0.154", 3.90mm Width)
• Mounting type: Surface Mount

The HIP6521CBZA meets all these criteria and qualifies as a parametric equivalent. Both parts share identical functional specifications, electrical characteristics, and physical packaging requirements, enabling direct substitution in applications designed for the HIP6521CB.

Parameter Comparison

Engineering Selection Recommendations

Both the HIP6521CB and HIP6521CBZA are classified as obsolete products. The HIP6521CBZA offers an advantage in regulatory compliance, meeting ROHS3 standards, whereas the HIP6521CB is RoHS non-compliant. For applications subject to RoHS requirements or environmental regulations, the HIP6521CBZA is the appropriate selection. Both parts are electrically and mechanically equivalent, supporting direct substitution based on identical parametric specifications and 16-SOIC packaging.

Frequently Asked Questions (FAQ)

Q: Can the HIP6521CBZA directly replace the HIP6521CB in existing designs?

A: Yes. Both parts share identical topology, output configuration, switching frequency, supply voltage range, operating temperature range, and 16-SOIC package dimensions. Direct substitution is supported without circuit modification.

Q: What is the primary difference between these two parts?

A: The HIP6521CBZA meets ROHS3 compliance standards, while the HIP6521CB is RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there any packaging considerations when substituting these parts?

A: Both parts use the 16-SOIC package with identical physical dimensions (0.154", 3.90mm Width). The HIP6521CBZA is supplied in Tube packaging. PCB layout and footprint compatibility is maintained.

Q: Why is the HIP6521CB classified as obsolete?

A: Obsolete status indicates the part is no longer in active production. The HIP6521CBZA serves as the available equivalent for continued system support and new designs.

Q: What parameters must match for a part to substitute the HIP6521CB?

A: Critical matching parameters include: 4-output topology (1 buck + 3 LDO), 300kHz switching frequency, 4.75V–5.25V supply voltage, 0°C–70°C operating temperature, and 16-SOIC surface mount package.
