AT-10.000MAGI-T Equivalent & Substitute Parts

Part Overview

The AT-10.000MAGI-T is a 10 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION in HC-49/US surface mount package. This component is classified as obsolete product status. The part is specified for 16pF load capacitance with 70 Ohms equivalent series resistance and operates across the industrial temperature range of -40°C to 85°C. Due to its obsolete classification, identifying equivalent substitute parts with matching electrical and mechanical parameters is necessary for design continuity and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT-10.000MAGI-T is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 10 MHz
• Frequency Tolerance: ±30ppm
• Load Capacitance: 16pF
• Operating Mode: Fundamental
• Package / Case: HC-49/US
• Mounting Type: Surface Mount
• Operating Temperature Range: -40°C to 85°C
• RoHS Compliance: Required
• AEC-Q200 Rating: Required

Allowable Variation Parameters:

• ESR (Equivalent Series Resistance): Tolerance within component specification limits
• Frequency Stability: ±50ppm specification maintained

Substitute parts must maintain identical mechanical dimensions and electrical performance within the specified operating envelope. Parts meeting these criteria are classified as parametric equivalents suitable for direct replacement in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The FTS AT-10.000MAGI-T variant qualifies as a parametric equivalent substitute for the obsolete TXC CORPORATION AT-10.000MAGI-T. Both parts maintain identical electrical specifications across frequency, tolerance, load capacitance, and operating temperature range. Both components carry AEC-Q200 automotive qualification and RoHS compliance certification.

The FTS variant carries active product status, ensuring ongoing availability and supply chain continuity. The ESR specification difference of 10 Ohms (80 Ohms versus 70 Ohms) falls within acceptable component tolerance ranges for 10 MHz crystal oscillators and does not impact circuit functionality within the specified operating parameters.

The FTS part is supplied in Tape & Reel packaging format, suitable for automated assembly processes, whereas the original TXC part was supplied in bulk packaging. Both parts maintain identical mechanical dimensions and HC-49/US package configuration, enabling direct physical and electrical substitution in surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can the FTS AT-10.000MAGI-T directly replace the TXC AT-10.000MAGI-T in existing designs?

A: Yes. Both parts meet identical electrical specifications for frequency, tolerance, load capacitance, and operating temperature range. Mechanical dimensions and package configuration are identical. The parts are parametric equivalents suitable for direct substitution.

Q: What is the significance of the ESR difference between the two parts?

A: The ESR specification difference of 10 Ohms (70 Ohms versus 80 Ohms) represents a 12.5% variation within normal component tolerance ranges for 10 MHz crystal oscillators. This variation does not affect circuit performance within the specified operating envelope.

Q: Are both parts qualified for automotive applications?

A: Yes. Both the TXC and FTS variants carry AEC-Q200 qualification, indicating suitability for automotive-grade applications across the specified temperature range of -40°C to 85°C.

Q: What is the difference between bulk and Tape & Reel packaging?

A: Bulk packaging is suitable for manual assembly and small-volume applications. Tape & Reel packaging is optimized for automated pick-and-place assembly processes in high-volume manufacturing. Both packaging formats contain identical components with identical electrical and mechanical specifications.

Q: Does the active product status of the FTS part provide supply advantages?

A: Yes. Active product status indicates ongoing manufacturing and distribution support. The FTS variant provides improved long-term availability compared to the obsolete TXC part, supporting extended production runs and future design revisions.

Q: Are both parts RoHS compliant?

A: Yes. Both the TXC and FTS AT-10.000MAGI-T variants are RoHS compliant and carry Moisture Sensitivity Level 1 (Unlimited) classification, indicating no special moisture handling requirements during storage or assembly.
