Substitute Part Grouping Explanation

Substitution of the 7V-26.000MAAV-T is determined by the following critical parameters: frequency (26 MHz), frequency stability (±30ppm), operating mode (Fundamental), operating temperature range (-20°C ~ 70°C), mounting type (Surface Mount), and package configuration (4-SMD, No Lead). Load capacitance and ESR are secondary parameters that influence circuit performance but do not prevent substitution when other core specifications align.

The substitute parts are grouped into two categories:

Category 1: Parametric Equivalents (Identical Load Capacitance) Parts with 8pF load capacitance and 60 Ohms ESR maintain full electrical equivalence to the main part. These include 7V-26.000MEEV-T (TXC CORPORATION, Cut Tape packaging) and XZAEECNANF-26.000000 (Taitien, 8pF, 100 Ohms ESR).

Category 2: Similar Parts (Variant Load Capacitance) Parts with different load capacitance values (6pF or 10pF) are functionally similar but require circuit design verification. These include 7V-26.000MEEQ-T (10pF, 60 Ohms ESR) and XZLEECNANF-26.000000 (6pF, 100 Ohms ESR).

All substitute parts maintain the same frequency, frequency stability, operating temperature range, and fundamental operating mode as the main part.

Engineering Selection Recommendations

Primary Equivalent (Direct Substitution): The 7V-26.000MEEV-T from TXC CORPORATION is the primary parametric equivalent, offering identical load capacitance (8pF), ESR (60 Ohms), frequency, stability, and temperature range. The only difference is packaging format (Cut Tape versus Tape & Reel). This part is suitable for direct substitution in applications where packaging format does not impose constraints.

Secondary Equivalent (Manufacturer Alternative): The XZAEECNANF-26.000000 from Taitien maintains 8pF load capacitance and identical frequency/stability specifications. The ESR is 100 Ohms (versus 60 Ohms in the main part) and physical dimensions are smaller (2.05mm x 1.65mm versus 3.20mm x 2.50mm). This part is suitable for space-constrained applications where the higher ESR is acceptable within circuit design margins.

Similar Parts (Load Capacitance Variants): The 7V-26.000MEEQ-T (10pF) and XZLEECNANF-26.000000 (6pF) differ in load capacitance specification. These parts are functionally similar but require circuit design verification to confirm compatibility with the application's oscillator circuit tuning and frequency accuracy requirements.

All substitute parts carry active product status and comply with RoHS and REACH requirements, confirming ongoing availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can 7V-26.000MEEV-T replace 7V-26.000MAAV-T directly? A: Yes. Both parts share identical electrical specifications (26 MHz, ±30ppm stability, 8pF load capacitance, 60 Ohms ESR) and physical package dimensions. The difference is packaging format (Cut Tape versus Tape & Reel). Direct substitution is supported if your assembly process accommodates Cut Tape format.

Q: What is the impact of different load capacitance values (6pF, 8pF, 10pF)? A: Load capacitance affects the oscillator circuit's tuning and frequency accuracy. The 7V-26.000MAAV-T is specified for 8pF load capacitance. Parts with 6pF or 10pF load capacitance require circuit design verification to confirm the oscillator circuit can achieve the required frequency and stability within the specified tolerance band.

Q: Can I use XZAEECNANF-26.000000 (Taitien) as a substitute? A: XZAEECNANF-26.000000 maintains the same frequency, stability, and load capacitance (8pF) as the main part. However, ESR is 100 Ohms (versus 60 Ohms) and physical dimensions are smaller. Substitution is supported if circuit design margins accommodate the higher ESR and if PCB layout can accommodate the smaller footprint (2.05mm x 1.65mm).

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging? A: Tape & Reel packaging is supplied on continuous tape wound on a reel, suitable for high-volume automated assembly. Cut Tape packaging is supplied as individual tape segments, suitable for lower-volume or manual assembly processes. Both formats contain identical components; the difference is in supply format and handling.

Q: Are all substitute parts RoHS compliant? A: Yes. The main part (7V-26.000MAAV-T) is RoHS Compliant. All substitute parts from TXC CORPORATION are RoHS Compliant. Substitute parts from Taitien (XZAEECNANF-26.000000, XZLEECNANF-26.000000) are ROHS3 Compliant. All parts meet RoHS regulatory requirements.

Q: What is Moisture Sensitivity Level (MSL) 1? A: MSL 1 indicates unlimited shelf life without moisture bake-out requirements. All listed parts carry MSL 1, confirming they do not require special moisture control during storage or handling.

Q: Can I substitute 7V-26.000MEEQ-T (10pF) for the main part? A: 7V-26.000MEEQ-T differs in load capacitance (10pF versus 8pF). Substitution requires circuit design verification to confirm the oscillator circuit can achieve the required frequency and stability with the different load capacitance specification. Direct substitution without circuit analysis is not supported.
