BA6566FP Equivalent & Substitute Parts

Part Overview

The BA6566FP is a Telecom IC Speech Network IC manufactured by Rohm Semiconductor, designed for interface applications in telecommunications equipment. This component operates within a supply voltage range of 1.15V to 1.27V and dissipates 1.35W of power. The part is currently in Last Time Buy status, indicating that original production has been discontinued and existing inventory represents the final availability from the manufacturer. Identifying equivalent substitute parts is necessary to ensure continued supply chain access and support for legacy system maintenance and repairs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA6566FP is determined by strict equivalence across the following critical parameters:

• Functional Classification: Speech Network IC interface function
• Electrical Specifications: Supply voltage range 1.15V ~ 1.27V; power dissipation 1.35W
• Circuit Configuration: Single circuit (1 circuit)
• Thermal Operating Range: -35°C ~ 60°C
• Physical Package: 24-SOP with 2 Heat Tabs (24-HSOP supplier package designation)
• Mounting Technology: Surface Mount

The BA6566FP-E2 meets all substitution criteria as it maintains identical electrical parameters, thermal specifications, circuit count, and physical packaging. The primary distinction between these parts is product status and packaging format (Tape & Reel for the substitute).

Parameter Comparison

Engineering Selection Recommendations

The BA6566FP-E2 is a direct parametric equivalent suitable for applications requiring Speech Network IC functionality within the specified electrical and thermal envelope. Both parts share identical core specifications: supply voltage 1.15V ~ 1.27V, power dissipation 1.35W, operating temperature range -35°C ~ 60°C, and 24-HSOP package configuration.

Selection between BA6566FP and BA6566FP-E2 should be based on:

• Inventory Status: BA6566FP (2200 Pcs available) versus BA6566FP-E2 (5258 Pcs available)
• Product Lifecycle: BA6566FP is Last Time Buy; BA6566FP-E2 is Not For New Designs
• Packaging Requirements: BA6566FP supplied in bulk format; BA6566FP-E2 supplied in Tape & Reel format
• Compliance Documentation: BA6566FP-E2 provides explicit ROHS3 compliance, REACH unaffected status, and MSL rating

For applications requiring regulatory compliance documentation, BA6566FP-E2 offers explicit certification records. For applications with existing bulk packaging infrastructure, BA6566FP remains available while inventory persists.

Frequently Asked Questions (FAQ)

Q: Can BA6566FP-E2 replace BA6566FP in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: supply voltage (1.15V ~ 1.27V), power dissipation (1.35W), operating temperature (-35°C ~ 60°C), circuit count (1), and package configuration (24-HSOP). Physical board layout and thermal management requirements remain unchanged.

Q: What is the difference between BA6566FP and BA6566FP-E2?

A: The parts are functionally identical. Differences are limited to product status (Last Time Buy vs. Not For New Designs), packaging format (bulk vs. Tape & Reel), and available compliance documentation (BA6566FP-E2 includes explicit ROHS3 and REACH certifications).

Q: Are there any package compatibility concerns?

A: No. Both parts use the identical 24-SOP package with 2 Heat Tabs (24-HSOP designation). Pin configuration, footprint, and thermal interface remain unchanged. Existing PCB designs require no modification.

Q: What does "Last Time Buy" status mean for BA6566FP?

A: Last Time Buy indicates that the manufacturer has discontinued production and the available inventory represents the final stock. Once depleted, the part will no longer be available from the manufacturer. BA6566FP-E2 offers an alternative source, though it carries "Not For New Designs" status, indicating it is also in end-of-life phase.

Q: Should I select based on packaging format?

A: Packaging format (bulk vs. Tape & Reel) depends on assembly process requirements. Tape & Reel format (BA6566FP-E2) is standard for automated pick-and-place assembly. Bulk format (BA6566FP) may be suitable for manual assembly or lower-volume applications. Both formats contain electrically identical components.
