7A-12.000MBBK-T Equivalent & Substitute Parts

Part Overview

The 7A-12.000MBBK-T is a 12 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION in a 2-SMD, no-lead surface mount package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. The crystal operates at 12 MHz with ±50ppm frequency stability and 20pF load capacitance, suitable for timing and clock generation applications in electronic systems.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete 7A-12.000MBBK-T is determined by strict equivalence across the following critical parameters:

• Frequency: 12 MHz (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Load Capacitance: 20pF (exact match required)
• ESR: 80 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -20°C to 70°C (exact match required)
• Package Configuration: 2-SMD, No Lead surface mount (exact match required)
• Physical Dimensions: 5.00mm × 3.20mm × 1.35mm maximum height (exact match required)
• RoHS Compliance: Required for regulatory alignment

Substitute parts must satisfy all parameters listed above without deviation. Packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The FTS 7A-12.000MBBK-T represents a direct parametric equivalent to the obsolete TXC CORPORATION 7A-12.000MBBK-T. All electrical and mechanical specifications are identical across frequency, stability, load capacitance, ESR, operating mode, temperature range, package configuration, and physical dimensions.

Product Status Consideration: The FTS variant carries an Active product status, ensuring ongoing availability and supply chain continuity. The TXC original is classified as Obsolete, making the FTS substitute the appropriate selection for new designs and production continuity.

Compliance Alignment: Both parts maintain RoHS Compliance and MSL Rating 1 (Unlimited), satisfying regulatory and environmental requirements without modification to circuit design or assembly processes.

Packaging Consideration: The FTS part is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly. The original TXC part was supplied in bulk format. This difference does not affect electrical performance or mechanical fit; it reflects standard industry packaging for active production components.

Frequently Asked Questions (FAQ)

Q: Can the FTS 7A-12.000MBBK-T be used as a direct replacement for the TXC 7A-12.000MBBK-T?

A: Yes. All electrical parameters (frequency, stability, load capacitance, ESR, operating mode, temperature range) and mechanical specifications (package type, dimensions, height) are identical. The components are pin-compatible and functionally equivalent.

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

A: Obsolete status indicates the manufacturer has discontinued production. The FTS equivalent provides continuity for applications requiring this specific 12 MHz crystal specification.

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

A: No. Tape & Reel is a standard packaging format for surface mount components and is compatible with automated assembly equipment. It does not alter electrical performance or mechanical fit.

Q: Are there any differences in RoHS or environmental compliance between the two parts?

A: No. Both parts are RoHS Compliant with MSL Rating 1 (Unlimited). Environmental and regulatory requirements are satisfied identically.

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

A: Frequency (12 MHz), frequency stability (±50ppm), load capacitance (20pF), ESR (80 Ohms), operating mode (Fundamental), operating temperature range (-20°C to 70°C), package type (2-SMD, No Lead), and physical dimensions (5.00 × 3.20 × 1.35mm) must all match exactly.

Q: Is the FTS part suitable for new production designs?

A: Yes. The Active product status and full compliance with all electrical and mechanical specifications make the FTS 7A-12.000MBBK-T appropriate for new designs requiring a 12 MHz fundamental mode crystal with these specifications.
