TSB82AA2IPGE IEEE 1394 Link Layer Controller Equivalent & Substitute Parts

Part Overview

The TSB82AA2IPGE is an IEEE 1394 Link Layer Controller implementing the OHCI-Lynx™ PCI interface standard. This component functions as a bridge between PCI host systems and IEEE 1394a-2000 FireWire networks, enabling high-speed serial communication in legacy and embedded applications.

The main part (TSB82AA2IPGE) carries an Obsolete product status, making substitute identification critical for ongoing system support and new design implementations. Active and Last Time Buy alternatives are available within the TSB82 series, providing continuity for applications requiring IEEE 1394 connectivity.

Substitute Part Grouping Explanation

Substitution eligibility for the TSB82AA2IPGE is determined by strict parameter matching across the following criteria:

Mandatory Matching Parameters:

• Protocol: IEEE 1394
• Function: Link Layer Controller
• Interface: PCI
• Standards: IEEE 1394a-2000, OHCI-Lynx™
• Voltage Supply: 3V ~ 3.6V
• Operating Temperature: 0°C ~ 70°C
• Package: 144-LQFP (20x20)
• RoHS Status: ROHS3 Compliant
• REACH Status: REACH Unaffected

All three substitute parts (TSB82AA2BIPGE, TSB82AA2BPGE, TSB82AA2PGE) meet these mandatory parameters. Differences in product status, packaging format, and moisture sensitivity level (MSL) do not affect functional equivalence but influence application context and supply chain considerations.

Parameter Comparison

Engineering Selection Recommendations

For Active Production Designs: TSB82AA2BIPGE and TSB82AA2BPGE are recommended as primary substitutes. Both carry Active product status, ensuring long-term availability and manufacturing support. TSB82AA2BIPGE provides standard packaging, while TSB82AA2BPGE offers Tray packaging for high-volume assembly operations. MSL rating of 2 (1 Year) is suitable for standard manufacturing environments.

For Legacy System Support: TSB82AA2PGE serves as a secondary substitute with Last Time Buy status, providing extended inventory (5060 units) for maintenance and repair applications. The higher MSL rating of 3 (168 Hours) requires controlled storage conditions but does not affect electrical performance.

Compliance Considerations: All substitute parts maintain ROHS3 compliance and REACH Unaffected status, matching the original part's regulatory posture. Selection should prioritize Active status parts for new designs and long-term system continuity.

Frequently Asked Questions (FAQ)

Q: Can TSB82AA2BIPGE directly replace TSB82AA2IPGE in existing designs? A: Yes. Both parts share identical electrical parameters (voltage, temperature range, protocol, interface, and standards compliance). The functional performance in IEEE 1394 PCI interface applications is equivalent. Verify PCB layout compatibility with the 144-LQFP package footprint.

Q: What is the difference between TSB82AA2BPGE and TSB82AA2BIPGE? A: The primary difference is packaging format. TSB82AA2BPGE is supplied in Tray packaging, while TSB82AA2BIPGE uses standard packaging. Electrical and functional specifications are identical. Selection depends on assembly process requirements and inventory management practices.

Q: Why does TSB82AA2PGE have higher inventory despite Last Time Buy status? A: Last Time Buy status indicates no future production orders will be accepted, but existing stock remains available. The higher inventory level (5060 units) reflects the final manufacturing run. This part is suitable for applications requiring extended component availability during the Last Time Buy window.

Q: Are there any temperature or voltage derating considerations between these parts? A: No. All substitute parts operate within the identical voltage range (3V ~ 3.6V) and temperature range (0°C ~ 70°C). No derating adjustments are required when substituting between these parts.

Q: What does MSL rating mean for component selection? A: Moisture Sensitivity Level (MSL) defines storage and handling requirements. MSL 1 (Unlimited) has no moisture restrictions. MSL 2 (1 Year) requires dry storage for up to one year. MSL 3 (168 Hours) requires baking before reflow if exposed to moisture. Select based on your manufacturing environment and storage capabilities.

Q: Is the 144-LQFP package identical across all substitute parts? A: Yes. All parts use the 144-LQFP (20x20) package with identical pin configuration, footprint, and mechanical dimensions. PCB layout and assembly processes require no modification when substituting between these parts.
