Engineering Selection Recommendations

Direct Substitution (No Circuit Modification Required):

The 7M-20.000MAHV-T from TXC CORPORATION provides direct electrical equivalence to the primary part with identical frequency, stability, load capacitance, and ESR specifications. The only difference is packaging format (Cut Tape versus Tape & Reel) and a 0.10mm reduction in seated height. This part is suitable for direct replacement in production environments where packaging format flexibility exists.

The 7V-20.000MAHV-T from FTS and QT325G-20.000MAHV-T from QST are parametric equivalents with identical electrical and physical specifications. Both parts maintain Active product status and RoHS compliance, supporting long-term design continuity.

Conditional Substitution (Circuit Design Evaluation Required):

The ILCX13-FF5F10-20.000MHZ from ILSI matches all primary criteria but specifies 10pF load capacitance versus the 8pF requirement. This part is suitable only when the application circuit can accommodate the higher load capacitance specification without frequency deviation exceeding system tolerance.

The RH100-20.000-8-3030-EXT-TR from Raltron Electronics maintains 8pF load capacitance but specifies 70 Ohms ESR versus 60 Ohms. The 10 Ohm increase in series resistance may impact circuit startup characteristics and should be evaluated against oscillator design margins.

The R2016-20.000-10-3030-EXT-TR from Raltron Electronics presents multiple parameter variations: 10pF load capacitance, 200 Ohms ESR, and significantly reduced physical dimensions (2.00mm x 1.60mm). This part is suitable only for applications with explicit design accommodation for these parameter changes and PCB layout modifications.

Compliance and Availability:

All substitute parts maintain Active product status and RoHS compliance. The TXC CORPORATION 7M-20.000MAHV-T offers the highest inventory availability (2251 pcs) among direct substitutes. The ILSI ILCX13-FF5F10-20.000MHZ provides the largest inventory reserve (6672 pcs) for extended supply chain security.

Frequently Asked Questions (FAQ)

Q: Can the 7M-20.000MAHV-T be used as a direct replacement for the 7V-20.000MAHV-T?

A: Yes. The 7M-20.000MAHV-T from TXC CORPORATION is a direct electrical equivalent with identical frequency (20.000 MHz), frequency stability (±30ppm), load capacitance (8pF), and ESR (60 Ohms). The difference is packaging format: the 7M series is supplied in Cut Tape format while the 7V series is supplied in Tape & Reel format. Both are suitable for surface mount assembly. The 7M variant has a 0.10mm lower seated height (0.80mm versus 0.90mm), which is within typical PCB assembly tolerances.

Q: What is the difference between the ILCX13-FF5F10-20.000MHZ and the primary part?

A: The ILCX13-FF5F10-20.000MHZ matches frequency, stability, and ESR specifications but specifies 10pF load capacitance instead of 8pF. Load capacitance affects the oscillator circuit's frequency calibration. Substitution requires verification that the application circuit can operate within specification with the higher load capacitance value. This part is not a direct drop-in replacement without circuit evaluation.

Q: Why does the R2016-20.000-10-3030-EXT-TR have such different physical dimensions?

A: The R2016 series represents a different package family (2.00mm x 1.60mm versus 3.20mm x 2.50mm). While it maintains the required 20 MHz frequency and ±30ppm stability, the smaller footprint and significantly higher ESR (200 Ohms versus 60 Ohms) require explicit design accommodation. This part is suitable only for applications with PCB layout modifications and oscillator circuit re-evaluation.

Q: Are all substitute parts RoHS compliant?

A: Yes. The primary part 7V-20.000MAHV-T is RoHS Compliant. All substitute parts listed maintain either RoHS Compliant or ROHS3 Compliant status, ensuring regulatory compliance across all options.

Q: What is the significance of load capacitance in crystal selection?

A: Load capacitance (specified in pF) is a critical parameter that determines the frequency at which the crystal oscillates within a given circuit. The primary part specifies 8pF. Substitute parts with 10pF load capacitance will oscillate at a different frequency in the same circuit unless the circuit design is modified. Parts with matching load capacitance (8pF) are preferred for direct substitution.

Q: Can I substitute the RH100-20.000-8-3030-EXT-TR for the primary part?

A: The RH100-20.000-8-3030-EXT-TR maintains the same frequency, stability, and load capacitance but specifies 70 Ohms ESR versus 60 Ohms. The 10 Ohm difference may affect oscillator startup time and power consumption. Substitution is permissible only after verification that the oscillator circuit design accommodates the higher ESR specification.

Q: What is MSL rating and why is it important?

A: MSL (Moisture Sensitivity Level) rating indicates the component's sensitivity to moisture absorption during storage and handling. All listed parts have MSL 1 rating, which means Unlimited shelf life under normal storage conditions. This ensures consistent component reliability regardless of storage duration.

Q: Are the FTS and QST variants true equivalents?

A: Yes. The 7V-20.000MAHV-T from FTS and QT325G-20.000MAHV-T from QST are parametric equivalents with identical electrical specifications (20.000 MHz, ±30ppm, 8pF, 60 Ohms) and physical dimensions (3.20mm x 2.50mm). Both maintain Active product status and appropriate RoHS compliance, supporting direct substitution.
