AT-11.2896MAGK-T Crystal Equivalent & Substitute Parts

Part Overview

The AT-11.2896MAGK-T is a 11.2896 MHz surface mount crystal manufactured by TXC CORPORATION in HC-49/US package format. This component is classified as obsolete, indicating discontinued production and limited availability through standard distribution channels. The part operates at fundamental mode with 20pF load capacitance and 70 Ohms equivalent series resistance, designed for applications requiring precise frequency reference in the 11.2896 MHz band.

Identification of equivalent and substitute parts is necessary due to the obsolete status of the original TXC CORPORATION component. Substitute parts maintain identical electrical and mechanical specifications while offering active production status and improved supply chain availability.

Substitute Part Grouping Explanation

Substitution of the AT-11.2896MAGK-T is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Frequency: 11.2896 MHz (exact match required)
• Frequency Tolerance: ±30 ppm (exact match required)
• Frequency Stability: ±50 ppm (exact match required)
• Load Capacitance: 20 pF (exact match required)
• Equivalent Series Resistance: 70 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)

Mechanical Equivalence Criteria:

• Package / Case: HC-49/US (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Physical Dimensions: 11.40mm L x 4.80mm W (exact match required)
• Height - Seated (Max): 4.10 mm (exact match required)

Environmental & Compliance Criteria:

• Operating Temperature Range: -40°C to +85°C (exact match required)
• RoHS Compliance: Required
• AEC-Q200 Rating: Required
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must satisfy all criteria listed above to ensure direct functional and mechanical interchangeability without circuit redesign or PCB layout modification.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: AT-11.2896MAGK-T (FTS)

The FTS AT-11.2896MAGK-T is a direct parametric equivalent to the obsolete TXC CORPORATION component. All electrical specifications, mechanical dimensions, and environmental operating parameters are identical. The FTS variant maintains active production status, ensuring long-term supply chain availability and consistent quality control.

Compliance & Certification Alignment: Both the original and substitute parts carry AEC-Q200 automotive-grade qualification and RoHS compliance certification. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage or handling.

Packaging Consideration: The FTS substitute is supplied in Tape & Reel (TR) format, which differs from the original part's unspecified packaging. For applications requiring specific packaging formats, packaging conversion services or alternative sourcing may be necessary.

Supply Chain Advantage: The FTS variant demonstrates superior inventory availability (2335 Pcs vs. 872 Pcs), supporting both immediate procurement needs and long-term production planning.

Frequently Asked Questions (FAQ)

Q: Can the FTS AT-11.2896MAGK-T be used as a direct replacement for the TXC AT-11.2896MAGK-T?

A: Yes. Both parts are parametrically equivalent across all electrical and mechanical specifications. No circuit redesign or PCB layout modification is required. Direct substitution is supported by identical frequency, load capacitance, ESR, package dimensions, and operating temperature range.

Q: What are the critical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by exact equivalence in: frequency (11.2896 MHz), frequency tolerance (±30 ppm), load capacitance (20 pF), ESR (70 Ohms), package type (HC-49/US), physical dimensions (11.40 x 4.80 mm), and operating temperature range (-40 to +85°C). Deviation in any of these parameters invalidates substitution.

Q: Does the Tape & Reel packaging of the FTS part affect electrical performance?

A: No. Packaging format (Tape & Reel vs. other formats) does not affect electrical or mechanical performance. The packaging difference is logistical only and relates to handling, storage, and assembly processes.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the TXC and FTS variants carry AEC-Q200 qualification, confirming suitability for automotive-grade applications with specified reliability and quality standards.

Q: What is the significance of the MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity constraints. The part does not require special moisture-controlled storage conditions and can be stored and handled under standard industrial conditions without risk of moisture-induced failure.

Q: Why is the original TXC part listed as obsolete?

A: Obsolete status indicates that TXC CORPORATION has discontinued production of this component. The FTS equivalent ensures continued availability of this frequency specification through an active manufacturer, supporting ongoing production and field service requirements.
