40 MHz ±30ppm Crystal 8pF SMD (8Y-40.000MAAV-T)

Part Overview

The 8Y-40.000MAAV-T is a 40 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION, designed for surface mount applications in 4-SMD, No Lead package configuration. This active product operates across the temperature range of -20°C to 70°C with ±30ppm frequency stability and tolerance specifications. The component is RoHS Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific application parameters that permit load capacitance variation within acceptable circuit design margins.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 8Y-40.000MAAV-T is determined by the following critical parameters:

Primary Matching Criteria:

• Frequency: 40 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Frequency Tolerance: ±30ppm (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 / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Consideration:

• Load Capacitance: Variation permitted within circuit design specifications (8pF, 10pF, or 6pF)

All identified substitute parts maintain identical frequency, stability, tolerance, ESR, operating mode, temperature range, and package configuration. Load capacitance variations are acceptable when circuit design accommodates the specified load capacitance of the substitute component.

Parameter Comparison

Engineering Selection Recommendations

All four components listed maintain active product status and full compliance with current regulatory standards. Selection between the 8Y-40.000MAAV-T and its substitutes is determined by load capacitance requirements specific to the application circuit design.

8Y-40.000MAAV-T (TXC CORPORATION): Primary specification with 8pF load capacitance. RoHS Compliant. Tape & Reel packaging. 1088 units in stock.

8Q-40.000MAAQ-T (FTS): Substitute with 10pF load capacitance. RoHS Compliant. Tape & Reel packaging. Smallest physical dimensions (1.60mm x 1.20mm) and lowest seated height (0.40mm). 3403 units in stock.

XZAEECNANF-40.000000 (Taitien): Substitute with 8pF load capacitance (matches primary specification). ROHS3 Compliant. Cut Tape packaging. 1155 units in stock.

XZLEECNANF-40.000000 (Taitien): Substitute with 6pF load capacitance. ROHS3 Compliant. Cut Tape packaging. 1405 units in stock.

All components are MSL 1 (Unlimited moisture sensitivity), eliminating moisture-related handling constraints. Selection should prioritize load capacitance compatibility with circuit design specifications.

Frequently Asked Questions (FAQ)

Q: Can the 8Q-40.000MAAQ-T with 10pF load capacitance replace the 8Y-40.000MAAV-T with 8pF load capacitance?

A: The 8Q-40.000MAAQ-T is electrically equivalent in frequency, stability, tolerance, ESR, operating mode, and temperature range. Substitution is valid when the circuit design accommodates 10pF load capacitance. Load capacitance differences affect oscillator startup characteristics and frequency accuracy; circuit design must specify acceptable load capacitance range.

Q: What is the difference between the Taitien XZAEECNANF-40.000000 and XZLEECNANF-40.000000?

A: Both Taitien components are identical except for load capacitance: XZAEECNANF-40.000000 specifies 8pF (matching the primary part), while XZLEECNANF-40.000000 specifies 6pF. All other electrical and mechanical parameters are identical. Selection depends on circuit load capacitance requirements.

Q: Does packaging format (Tape & Reel vs. Cut Tape) affect electrical performance?

A: Packaging format does not affect electrical performance. Tape & Reel (TR) packaging is suitable for automated assembly processes, while Cut Tape (CT) packaging is appropriate for manual or lower-volume assembly. Selection is based on manufacturing process requirements, not component functionality.

Q: Are all substitute parts RoHS compliant?

A: Yes. The primary part (8Y-40.000MAAV-T) is RoHS Compliant. The FTS substitute (8Q-40.000MAAQ-T) is RoHS Compliant. Both Taitien substitutes (XZAEECNANF-40.000000 and XZLEECNANF-40.000000) are ROHS3 Compliant. All meet current regulatory requirements.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life and does not require special moisture-controlled storage or handling procedures. All four components share this rating, eliminating moisture sensitivity as a selection criterion.

Q: Can physical dimension differences between parts affect PCB layout?

A: Yes. The 8Q-40.000MAAQ-T has the smallest footprint (1.60mm x 1.20mm) and lowest height (0.40mm). The primary part and Taitien substitutes have larger footprints (2.00-2.05mm x 1.60-1.65mm) and greater height (0.55mm). PCB layout and component placement must accommodate the selected part's physical dimensions.

Q: Which substitute offers the best inventory availability?

A: The 8Q-40.000MAAQ-T (FTS) has the highest inventory level at 3403 units in stock, followed by XZLEECNANF-40.000000 (Taitien) at 1405 units, XZAEECNANF-40.000000 (Taitien) at 1155 units, and the primary part at 1088 units.
