9B-11.2896MAAJ-B Equivalent & Substitute Parts

Part Overview

The 9B-11.2896MAAJ-B is a through-hole crystal oscillator manufactured by TXC CORPORATION, operating at a fundamental frequency of 11.2896 MHz with a load capacitance of 18pF and an equivalent series resistance (ESR) of 40 Ohms. The device is housed in an HC-49/US package and is rated for operation across a temperature range of -20°C to 70°C.

This part carries an obsolete product status. Locating equivalent or substitute components becomes necessary when original inventory is depleted, when procurement lead times are extended, or when design requirements permit the use of alternative components with compatible electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution of the 9B-11.2896MAAJ-B is permissible when the replacement component maintains the following critical parameters:

• Frequency: Exact match at 11.2896 MHz
• Load Capacitance: Exact match at 18pF
• Equivalent Series Resistance (ESR): Exact match at 40 Ohms
• Package / Case: Identical HC-49/US form factor
• Mounting Type: Through-hole configuration
• Operating Temperature Range: Minimum coverage of -20°C to 70°C

The 9B-11.2896MEEJ-B qualifies as a direct substitute because it maintains all critical electrical parameters and mechanical specifications. The primary distinction between these components is the frequency stability specification: the main part is rated at ±30ppm, while the substitute is rated at ±10ppm. This represents an improvement in frequency stability and does not restrict substitution in applications designed for the original part.

Parameter Comparison

*Compatible: The substitute part exhibits superior frequency stability (±10ppm vs. ±30ppm), which is a performance enhancement and does not compromise compatibility with circuits designed for the original specification.

Engineering Selection Recommendations

Both the 9B-11.2896MAAJ-B and 9B-11.2896MEEJ-B are classified as obsolete products. Selection between these components should be based on the following criteria:

Primary Selection (9B-11.2896MEEJ-B): This part is recommended when inventory availability permits. It provides improved frequency stability at ±10ppm compared to the original ±30ppm specification. Both components carry identical RoHS3 compliance and REACH-affected status, ensuring regulatory alignment. The enhanced stability of the substitute part introduces no compatibility risk and may provide performance benefits in precision timing applications.

Alternative Selection (9B-11.2896MAAJ-B): This part remains suitable for applications where the original ±30ppm frequency stability specification is acceptable. Selection of this component should be based solely on inventory availability and procurement lead time considerations.

Both components are manufactured by TXC CORPORATION and share identical mechanical dimensions, mounting characteristics, and environmental ratings. Substitution between these parts requires no circuit modifications or design changes.

Frequently Asked Questions (FAQ)

Q: Can the 9B-11.2896MEEJ-B be used as a direct replacement for the 9B-11.2896MAAJ-B?

A: Yes. Both components operate at 11.2896 MHz with identical load capacitance (18pF), ESR (40 Ohms), package type (HC-49/US), and mounting configuration (through-hole). The substitute part meets or exceeds all electrical and mechanical specifications of the original component.

Q: What is the significance of the frequency stability difference between ±30ppm and ±10ppm?

A: Frequency stability defines the maximum deviation of the oscillation frequency from the nominal value across the operating temperature range and over time. The 9B-11.2896MEEJ-B exhibits tighter frequency stability, meaning its output frequency remains closer to 11.2896 MHz under varying conditions. This represents an improvement and does not restrict substitution in applications designed for the original ±30ppm specification.

Q: Are there any physical differences between these components?

A: No. Both parts share identical dimensions (11.50 x 5.00 mm), maximum seated height (3.68 mm), and HC-49/US package form factor. They are mechanically interchangeable without any modifications to the printed circuit board or mounting hardware.

Q: Do both parts comply with current regulatory standards?

A: Yes. Both the 9B-11.2896MAAJ-B and 9B-11.2896MEEJ-B are ROHS3 compliant and REACH-affected, meeting current environmental and hazardous substance regulations.

Q: Why are both parts classified as obsolete?

A: Obsolete status indicates that these components are no longer in active production by the manufacturer. This classification does not affect their electrical performance or reliability when in use; it reflects the manufacturer's decision to discontinue production. Existing inventory remains available for procurement through authorized distributors.
