XYLEECNANF-40.000000 Equivalent & Substitute Parts

Part Overview

The XYLEECNANF-40.000000 is a 40 MHz fundamental mode crystal oscillator manufactured by Taitien, designed for surface mount applications requiring precise frequency generation. This Active product is specified with 6pF load capacitance, ±30ppm frequency stability, and operates across the -20°C to 70°C temperature range. The component is housed in a 4-SMD, No Lead package measuring 2.55mm × 2.05mm with a maximum seated height of 0.55mm. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameter range.

Substitute Part Grouping Explanation

The XZLEECNANF-40.000000 qualifies as a substitute for the XYLEECNANF-40.000000 based on the following critical parameters:

  • Identical frequency specification: 40 MHz
  • Matching frequency stability: ±30ppm
  • Equivalent load capacitance: 6pF
  • Same operating mode: Fundamental
  • Identical temperature range: -20°C ~ 70°C
  • Compatible mounting: Surface Mount, 4-SMD, No Lead package
  • Equivalent compliance: ROHS3 Compliant, MSL 1

The primary difference between these parts is the ESR (Equivalent Series Resistance): the main part specifies 60 Ohms while the substitute specifies 80 Ohms. This variance remains within acceptable tolerance for 40 MHz crystal applications and does not compromise functional compatibility. Secondary differences include packaging format (Tape & Reel versus Cut Tape) and physical dimensions (2.55mm × 2.05mm versus 2.05mm × 1.65mm), both of which are compatible with standard surface mount assembly processes.

Engineering Selection Recommendations

Both the XYLEECNANF-40.000000 and XZLEECNANF-40.000000 maintain Active product status with full ROHS3 compliance and MSL 1 rating, confirming suitability for current manufacturing and long-term storage without moisture sensitivity constraints. Selection between these parts should be based on packaging availability and inventory requirements rather than electrical performance, as the specified parameters are functionally equivalent. The XZLEECNANF-40.000000 offers a smaller footprint (2.05mm × 1.65mm) compared to the main part (2.55mm × 2.05mm), which may provide layout advantages in space-constrained applications while maintaining identical electrical characteristics and temperature performance.

Frequently Asked Questions (FAQ)

Q: Can the XZLEECNANF-40.000000 directly replace the XYLEECNANF-40.000000 in existing designs?

A: Yes. Both parts share identical frequency, stability, load capacitance, operating mode, and temperature range specifications. The 20 Ohm ESR difference (60 Ohms versus 80 Ohms) is within acceptable tolerance for 40 MHz crystal applications and does not affect circuit functionality.

Q: What is the significance of the different ESR values?

A: ESR (Equivalent Series Resistance) affects crystal startup time and power consumption in oscillator circuits. The XZLEECNANF-40.000000 at 80 Ohms versus the XYLEECNANF-40.000000 at 60 Ohms represents a 33% increase in resistance. For most 40 MHz applications, this variance is accommodated by standard oscillator circuit design margins and does not compromise performance.

Q: Are there packaging considerations when switching between these parts?

A: Yes. The XYLEECNANF-40.000000 is supplied in Tape & Reel (TR) format, while the XZLEECNANF-40.000000 is supplied in Cut Tape (CT) format. Both are compatible with standard surface mount assembly equipment. The XZLEECNANF-40.000000 also features a smaller physical footprint, which may require PCB layout verification for space-constrained designs.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 Compliant, REACH Unaffected, and classified as MSL 1 (Unlimited moisture sensitivity level), confirming equivalent environmental and regulatory compliance.

Q: What is the maximum seated height for both parts?

A: Both parts specify a maximum seated height of 0.55mm, ensuring compatibility with standard surface mount assembly processes and clearance requirements.
