7M-20.000MAHI-T Crystal Oscillator Equivalent & Substitute Parts

Part Overview

The 7M-20.000MAHI-T is a 20 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION, designed for surface mount applications in a 4-SMD, No Lead package. This active product operates across the industrial temperature range of -40°C to 85°C with ±30ppm frequency stability and 16pF load capacitance. Substitute parts are identified when equivalent electrical and mechanical parameters are available from alternative manufacturers or when the primary part requires sourcing alternatives due to inventory constraints or application-specific requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M-20.000MAHI-T is determined by the following critical parameters:

Primary Substitution Criteria:

• Frequency: 20.0000 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 3.20mm x 2.50mm footprint (exact match required)

Secondary Compatibility Parameters:

• Load Capacitance: 16pF (primary specification; 12pF variants acceptable with circuit design verification)
• ESR: 60 Ohms (primary specification; higher ESR values acceptable within circuit tolerance limits)
• Mounting Type: Surface Mount (exact match required)
• RoHS Compliance: Required for regulatory alignment

The 7M-20.000MAHI-T has two identified substitute parts: the 7M-20.000MAHE-T (TXC CORPORATION, 12pF load capacitance) and the C3E-20.000-12-3030-X-R (Aker Technology Corp, 12pF load capacitance, 100 Ohms ESR). Both substitutes maintain identical frequency, stability, temperature range, and package specifications while differing in load capacitance and ESR characteristics.

Parameter Comparison

Engineering Selection Recommendations

7M-20.000MAHI-T (Primary Part): Select this part when the application circuit is designed for 16pF load capacitance and 60 Ohms ESR. The part maintains active product status with RoHS compliance and unlimited moisture sensitivity rating, suitable for standard industrial applications.

7M-20.000MAHE-T (TXC CORPORATION Substitute): This substitute is electrically compatible when the application circuit can accommodate 12pF load capacitance. Identical frequency, stability, temperature range, and ESR (60 Ohms) specifications ensure direct functional equivalence with load capacitance adjustment. Both parts are manufactured by TXC CORPORATION with identical RoHS compliance and MSL ratings. Higher inventory availability (1306 Pcs) supports supply chain flexibility.

C3E-20.000-12-3030-X-R (Aker Technology Corp Substitute): This substitute is compatible when the application circuit accepts 12pF load capacitance and 100 Ohms ESR. Frequency, stability, and temperature specifications remain identical. ROHS3 compliance exceeds RoHS requirements. Significantly higher inventory (11289 Pcs) provides extended supply assurance. The 0.75mm maximum seated height (versus 0.80mm) requires verification of PCB assembly clearance specifications.

Selection Criteria:

• Use the primary part (7M-20.000MAHI-T) when 16pF load capacitance is specified in circuit design.
• Use 7M-20.000MAHE-T when 12pF load capacitance is acceptable and TXC CORPORATION sourcing is preferred.
• Use C3E-20.000-12-3030-X-R when 12pF load capacitance is acceptable, higher ESR tolerance is acceptable, and maximum inventory availability is required.

All three parts maintain identical frequency, stability, operating temperature, and fundamental mode operation across the specified industrial range.

Frequently Asked Questions (FAQ)

Q: Can the 7M-20.000MAHE-T replace the 7M-20.000MAHI-T directly?

A: The 7M-20.000MAHE-T is electrically compatible when the application circuit is designed for 12pF load capacitance. Both parts share identical frequency (20 MHz), frequency stability (±30ppm), ESR (60 Ohms), operating temperature range (-40 to 85°C), and package specifications (4-SMD, No Lead, 3.20 x 2.50mm). The primary difference is load capacitance: 16pF versus 12pF. Circuit design verification is required to confirm 12pF load capacitance compatibility.

Q: What is the impact of the higher ESR in the C3E-20.000-12-3030-X-R?

A: The C3E-20.000-12-3030-X-R has 100 Ohms ESR compared to 60 Ohms in the primary part. Higher ESR increases power dissipation and may affect oscillator startup characteristics. This substitute is compatible when the application circuit design accommodates 100 Ohms ESR. Circuit simulation or testing is recommended to confirm performance within specification.

Q: Are there physical dimension differences between these parts?

A: The 7M-20.000MAHI-T and 7M-20.000MAHE-T have identical dimensions (3.20 x 2.50 x 0.80mm). The C3E-20.000-12-3030-X-R has a maximum seated height of 0.75mm (versus 0.80mm). This 0.05mm difference requires verification against PCB assembly clearance specifications and solder reflow profile compatibility.

Q: Do all three parts meet RoHS requirements?

A: Yes. The 7M-20.000MAHI-T and 7M-20.000MAHE-T are RoHS Compliant. The C3E-20.000-12-3030-X-R is ROHS3 Compliant, which exceeds RoHS requirements. All parts are suitable for applications requiring RoHS compliance.

Q: What is the MSL rating for these crystals?

A: All three parts have MSL Rating 1 (Unlimited), indicating unlimited shelf life without moisture bake-out requirements. Standard moisture control during storage and handling applies.

Q: Which substitute offers the best inventory availability?

A: The C3E-20.000-12-3030-X-R offers the highest inventory availability with 11289 Pcs in stock, compared to 1306 Pcs for the 7M-20.000MAHE-T and 963 Pcs for the primary part. This availability advantage applies when 12pF load capacitance and 100 Ohms ESR are acceptable for the application.

Q: Are these parts suitable for high-temperature applications?

A: All three parts operate across -40°C to 85°C, which covers standard industrial temperature ranges. For applications requiring extended temperature operation beyond 85°C, alternative crystal specifications are required.
