ATA5551M-PP Equivalent & Substitute Parts

Part Overview

The ATA5551M-PP is a passive RFID tag read/write component operating at 125kHz with 224 bytes of user-writable memory in an encapsulated form factor. This component is classified as obsolete, necessitating identification of active equivalent parts for ongoing design requirements and procurement needs. The ATA5551M-PPMY serves as the direct active substitute, maintaining identical electrical and mechanical specifications while offering improved availability.

Key Parameters

Substitute Part Grouping Explanation

The ATA5551M-PPMY is classified as a direct equivalent to the ATA5551M-PP based on the following substitution criteria:

Electrical Parameters Match:

• Identical frequency specification (125kHz)
• Identical memory configuration (224b user-writable memory)
• Identical memory type (Read/Write)
• Identical technology classification (Passive)

Mechanical Parameters Match:

• Identical physical dimensions (0.492" L x 0.232" W / 12.10mm x 5.90mm)
• Identical packaging style (Encapsulated)

Compliance & Environmental Parameters Match:

• Identical operating temperature range (-40°C ~ 85°C)
• Identical RoHS status (ROHS3 Compliant)
• Identical moisture sensitivity level (MSL 1 - Unlimited)
• Identical REACH status (REACH Unaffected)

The substitution is valid across all specified electrical, mechanical, and environmental parameters. The primary distinction is product status: ATA5551M-PP is obsolete while ATA5551M-PPMY is active.

Parameter Comparison

Engineering Selection Recommendations

The ATA5551M-PPMY is the appropriate selection for applications currently specified with ATA5551M-PP. Both components maintain identical electrical performance across frequency, memory capacity, and memory type specifications. Both components satisfy identical mechanical requirements with matching physical dimensions and encapsulation style.

Compliance certifications are equivalent: both components are ROHS3 compliant, REACH unaffected, and rated for identical operating temperature ranges. The ATA5551M-PPMY offers the advantage of active product status with significantly higher inventory availability (23,200 units versus 977 units), supporting production continuity and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can ATA5551M-PPMY be used as a direct replacement for ATA5551M-PP?
