HIP6521CBZ Equivalent & Substitute Parts

Part Overview

The HIP6521CBZ 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 HIP6521CBZ is classified as obsolete. Locating equivalent substitute parts is necessary for design continuity, system maintenance, and component procurement when original inventory becomes unavailable.

Substitute Part Grouping Explanation

Substitute parts for the HIP6521CBZ are identified based on strict parametric equivalence across the following critical criteria:

• Topology: Step-Down (Buck) Synchronous (1), 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 (0.154", 3.90mm Width)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant

The HIP6521CBZA meets all these parameters and qualifies as a parametric equivalent. Both parts share the same base product number (HIP6521) and identical electrical and mechanical specifications, ensuring functional interchangeability within the defined operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the HIP6521CBZ and HIP6521CBZA are classified as obsolete products. Selection between these parts should be based on current inventory availability and procurement lead times from authorized distributors.

Both parts maintain ROHS3 compliance and identical electrical specifications, ensuring equivalent performance in applications designed for the HIP6521 series. The primary distinction is manufacturer origin: Renesas Electronics Corporation for the HIP6521CBZ and Intersil for the HIP6521CBZA.

For new designs or long-term production requirements, evaluation of current-generation PMIC alternatives with similar topologies and output configurations is recommended to ensure sustained component availability.

Frequently Asked Questions (FAQ)

Q: Can HIP6521CBZA be used as a direct replacement for HIP6521CBZ?

A: Yes. The HIP6521CBZA is a parametric equivalent with identical electrical specifications, switching frequency, supply voltage range, operating temperature range, and 16-SOIC package configuration. Both parts implement the same topology of one synchronous buck converter and three linear regulators.

Q: Are there differences in package dimensions between these parts?

A: No. Both parts use the 16-SOIC package with identical dimensions of 0.154" width (3.90mm). Pin-to-pin compatibility is maintained.

Q: What is the significance of the different manufacturers?

A: The HIP6521CBZ originates from Renesas Electronics Corporation, while the HIP6521CBZA is from Intersil. Both manufacturers produce parts meeting the same parametric specifications. Manufacturer selection may depend on distributor inventory, regional availability, and procurement agreements.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates these products are no longer in active production. Component sourcing should prioritize available inventory from authorized distributors. For applications requiring long-term component availability, evaluation of current-generation PMIC solutions is advisable.

Q: Are there compliance or certification differences?

A: Both parts maintain ROHS3 compliance and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring equivalent regulatory status for procurement and export purposes.
