Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7V-40.000MAHV-T is determined by the following critical parameters: frequency (40 MHz), frequency stability (±30ppm), operating temperature range (-40°C to 85°C), mounting type (Surface Mount), package type (4-SMD, No Lead), and physical footprint compatibility (3.20mm x 2.50mm).

The substitute parts are grouped into two categories:

Direct Substitutes (Identical Electrical Specifications): Parts that maintain all critical electrical parameters including load capacitance (8pF) and ESR (60 Ohms). The 7M-40.000MAHV-T from TXC CORPORATION qualifies as a direct substitute, differing only in series designation and seated height (0.031" vs 0.035").

Similar Substitutes (Compatible with Parameter Variations): Parts that maintain frequency, stability, temperature range, and package compatibility but differ in load capacitance or ESR. The ILCX13-FF5F10-40.000MHZ (10pF load capacitance, 40 Ohms ESR), XZAEELNANF-40.000000 (8pF load capacitance, 80 Ohms ESR), and XZLEELNANF-40.000000 (6pF load capacitance, 80 Ohms ESR) fall into this category. These parts require circuit design verification to confirm load capacitance and ESR compatibility with the application.

Parameter Comparison

Engineering Selection Recommendations

7M-40.000MAHV-T (TXC CORPORATION): This part is the primary direct substitute for the 7V-40.000MAHV-T. Both parts are manufactured by TXC CORPORATION with identical electrical specifications (40 MHz, ±30ppm stability, 8pF load capacitance, 60 Ohms ESR). The 7M series differs only in seated height (0.80mm vs 0.90mm), which is acceptable for most PCB assembly applications. Both parts are RoHS Compliant with MSL 1 rating. The 7M-40.000MAHV-T offers superior inventory availability (2637 units) compared to the main part.

ILCX13-FF5F10-40.000MHZ (ILSI): This substitute maintains frequency, stability, and temperature range compatibility. The load capacitance is 10pF (versus 8pF) and ESR is 40 Ohms (versus 60 Ohms). This part is suitable for applications where the circuit design accommodates higher load capacitance and lower ESR characteristics. ROHS3 Compliant status provides enhanced environmental compliance. Physical footprint remains compatible at 3.20mm x 2.50mm.

XZAEELNANF-40.000000 (Taitien): This part maintains 8pF load capacitance but features 80 Ohms ESR (versus 60 Ohms). The physical footprint is smaller (2.05mm x 1.65mm) with reduced seated height (0.55mm), enabling space-constrained applications. ESR tolerance must be verified against circuit requirements. ROHS3 Compliant. Packaging is Cut Tape (CT) rather than Tape & Reel (TR).

XZLEELNANF-40.000000 (Taitien): This part features 6pF load capacitance with 80 Ohms ESR. The smaller footprint (2.05mm x 1.65mm) and reduced height (0.55mm) support compact designs. Load capacitance variation requires circuit design confirmation. ROHS3 Compliant. Cut Tape packaging applies.

All substitute parts maintain the 40 MHz frequency, ±30ppm stability, -40°C to 85°C operating temperature, 4-SMD no-lead package type, and MSL 1 rating. Selection depends on specific circuit load capacitance requirements, ESR tolerance, physical space constraints, and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can the 7M-40.000MAHV-T be used as a direct replacement for the 7V-40.000MAHV-T without circuit modification?

A: Yes. The 7M-40.000MAHV-T is a direct electrical equivalent with identical frequency (40 MHz), stability (±30ppm), load capacitance (8pF), and ESR (60 Ohms). The only difference is seated height (0.80mm vs 0.90mm), which does not affect electrical performance or standard PCB assembly compatibility.

Q: What is the significance of load capacitance differences between substitute parts?

A: Load capacitance determines the crystal's operating frequency in the circuit. The main part specifies 8pF load capacitance. Substitutes with different load capacitance values (ILCX13-FF5F10-40.000MHZ at 10pF, XZLEELNANF-40.000000 at 6pF) require verification that the circuit's load capacitance network matches the crystal specification. Mismatched load capacitance can result in frequency deviation beyond the ±30ppm stability specification.

Q: How does ESR (Equivalent Series Resistance) affect part selection?

A: ESR influences circuit startup characteristics and frequency stability. The main part specifies 60 Ohms ESR. Substitutes with lower ESR (ILCX13-FF5F10-40.000MHZ at 40 Ohms) provide easier circuit startup. Substitutes with higher ESR (XZAEELNANF-40.000000 and XZLEELNANF-40.000000 at 80 Ohms) require verification that the oscillator circuit can sustain oscillation. ESR tolerance must align with circuit design specifications.

Q: Are the Taitien parts (XZAEELNANF-40.000000 and XZLEELNANF-40.000000) suitable for applications requiring the original 3.20mm x 2.50mm footprint?

A: No. The Taitien parts feature a smaller footprint of 2.05mm x 1.65mm. These parts are suitable only for space-constrained applications where the reduced size is beneficial. PCB layout modifications are required if switching from the original 3.20mm x 2.50mm footprint to the 2.05mm x 1.65mm footprint.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging is supplied on continuous reels suitable for high-volume automated assembly. Cut Tape packaging is supplied in individual tape segments suitable for lower-volume or manual assembly processes. The 7V-40.000MAHV-T and 7M-40.000MAHV-T use TR packaging. The Taitien substitutes (XZAEELNANF-40.000000 and XZLEELNANF-40.000000) use CT packaging, which may require different handling procedures.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part (7V-40.000MAHV-T) is RoHS Compliant. The 7M-40.000MAHV-T is also RoHS Compliant. The ILSI and Taitien substitutes are ROHS3 Compliant, which represents an enhanced compliance standard. All parts meet RoHS requirements for restricted substance elimination.

Q: Which substitute part offers the best inventory availability?

A: The 7M-40.000MAHV-T offers the highest inventory availability with 2637 units in stock, compared to 817 units for the main part. The ILCX13-FF5F10-40.000MHZ (1813 units), XZAEELNANF-40.000000 (1490 units), and XZLEELNANF-40.000000 (1520 units) provide additional sourcing options.
