AT-5.000MAGE-T Equivalent & Substitute Parts

Part Overview

The AT-5.000MAGE-T is a 5 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION, designed for surface mount applications in the HC-49/US package. This component operates across the industrial temperature range of -40°C to 85°C with ±30ppm frequency tolerance and ±50ppm stability, meeting AEC-Q200 automotive qualification standards.

The AT-5.000MAGE-T is classified as obsolete. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring 5 MHz crystal oscillators with identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the AT-5.000MAGE-T is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Frequency: 5 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Load Capacitance: 12pF (exact match required)
• ESR: 150 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)

Mechanical & Environmental Parameters:

• Package / Case: HC-49/US (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 0.449" L x 0.189" W, Height 0.161" max (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)

Compliance & Quality Parameters:

• AEC-Q200 Rating (required for automotive applications)
• RoHS Compliance (required for environmental standards)
• MSL Level 1 (required for moisture sensitivity)

Substitute parts must satisfy all parameters listed above without deviation. Parametric equivalents are identified based on complete alignment with these specifications.

Engineering Selection Recommendations

The FTS AT-5.000MAGE-T represents a parametric equivalent substitute for the obsolete TXC CORPORATION AT-5.000MAGE-T. Both components satisfy identical electrical, mechanical, and environmental specifications across all critical parameters.

Key Selection Factors:

Product Status: The FTS variant maintains Active product status, ensuring ongoing availability and supply chain continuity compared to the obsolete TXC original.

Compliance & Certifications: Both parts carry AEC-Q200 automotive qualification and RoHS compliance, maintaining regulatory and quality requirements for industrial and automotive applications.

Packaging Availability: The FTS substitute is available in Tape & Reel (TR) packaging, supporting automated assembly processes. Packaging format should be verified against assembly line requirements.

Electrical Equivalence: Complete parametric alignment across frequency (5 MHz), tolerance (±30ppm), stability (±50ppm), load capacitance (12pF), and ESR (150 Ohms) ensures direct functional replacement without circuit redesign.

Mechanical Compatibility: Identical HC-49/US package dimensions and surface mount configuration enable direct PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can the FTS AT-5.000MAGE-T directly replace the TXC AT-5.000MAGE-T in existing designs?

A: Yes. Both components are parametrically equivalent across all electrical specifications (frequency, tolerance, stability, load capacitance, ESR), mechanical dimensions (HC-49/US package, surface mount), and environmental ratings (AEC-Q200, RoHS, MSL Level 1). Direct substitution is supported without circuit modification.

Q: What is the significance of the obsolete status for the TXC original?

A: Obsolete status indicates the TXC AT-5.000MAGE-T is no longer manufactured or supported by the original supplier. The FTS equivalent, with Active product status, provides continued supply availability and manufacturer support for new designs and production runs.

Q: Are there any differences in packaging between the two parts?

A: The TXC original packaging format is not specified in available documentation. The FTS substitute is supplied in Tape & Reel (TR) packaging, which is standard for automated surface mount assembly. Verify packaging compatibility with your assembly process requirements.

Q: Do both parts meet automotive qualification standards?

A: Yes. Both the TXC original and FTS substitute carry AEC-Q200 ratings, confirming compliance with automotive industry reliability and quality standards.

Q: What parameters must remain identical for substitution to be valid?

A: Substitution requires exact equivalence in: frequency (5 MHz), frequency tolerance (±30ppm), frequency stability (±50ppm), load capacitance (12pF), ESR (150 Ohms), operating mode (Fundamental), operating temperature range (-40°C to 85°C), package type (HC-49/US), and mounting configuration (Surface Mount). Any deviation in these parameters invalidates the substitution.

Q: Is the FTS part RoHS compliant?

A: Yes. The FTS AT-5.000MAGE-T is RoHS compliant, matching the environmental compliance status of the TXC original.

Q: What is MSL Level 1, and why is it important?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture exposure precautions. Both parts carry MSL Level 1, eliminating moisture-related handling restrictions during storage and assembly.
