FL3000037 30 MHz Crystal Equivalent & Substitute Parts

Part Overview

The FL3000037 is a 30 MHz fundamental mode crystal manufactured by Diodes Incorporated in the SaRonix-eCera™ FL series. This surface mount device is specified for 10pF load capacitance with 40 Ohms equivalent series resistance (ESR) in a 4-SMD, No Lead package. The part is active in production status and RoHS3 compliant. Substitute parts are identified when equivalent frequency, stability, operating mode, temperature range, and package type specifications are maintained, with allowable variations in load capacitance and ESR within acceptable circuit design tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FL3000037 are qualified based on the following critical parameters that must remain constant:

• Frequency: 30 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -20°C ~ 70°C (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)

Allowable variations in substitute parts:

• Load Capacitance: May vary from 10pF to 8pF (circuit design dependent)
• ESR: May vary from 40 Ohms to 100 Ohms (within acceptable oscillator circuit margins)
• Physical dimensions: Minor variations permitted within SMD package classification
• Packaging format: Both Tape & Reel (TR) and Cut Tape (CT) formats acceptable

The two qualified substitute parts maintain all critical parameters while presenting acceptable variations in load capacitance and ESR specifications.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active production status and meet RoHS compliance requirements. The FL3000037 (Diodes Incorporated) and XZAEECNANF-30.000000 (Taitien) are ROHS3 compliant, while the 8Z-30.000MAAV-T (TXC) is RoHS compliant. All parts carry MSL 1 rating, indicating unlimited moisture sensitivity protection.

Selection between these parts depends on circuit design tolerance for load capacitance and ESR variations. The FL3000037 offers the lowest ESR at 40 Ohms with 10pF load capacitance. The 8Z-30.000MAAV-T provides a mid-range ESR of 60 Ohms with 8pF load capacitance. The XZAEECNANF-30.000000 presents the highest ESR at 100 Ohms with 8pF load capacitance. All three parts are suitable for applications where the oscillator circuit design accommodates these parameter ranges.

Frequently Asked Questions (FAQ)

Q: Can I substitute the FL3000037 with the 8Z-30.000MAAV-T?

A: Yes. Both parts share identical frequency (30 MHz), frequency stability (±30ppm), operating mode (Fundamental), temperature range (-20°C ~ 70°C), and package type (4-SMD, No Lead). The load capacitance differs by 2pF (10pF vs 8pF) and ESR differs by 20 Ohms (40 vs 60 Ohms). Substitution is valid if your oscillator circuit design accommodates these parameter variations.

Q: What is the difference between the two substitute parts?

A: Both 8Z-30.000MAAV-T and XZAEECNANF-30.000000 operate at 30 MHz with ±30ppm stability and identical temperature range. The primary differences are ESR (60 Ohms vs 100 Ohms) and physical dimensions. The 8Z-30.000MAAV-T is larger (2.50mm x 2.00mm) while the XZAEECNANF-30.000000 is smaller (2.05mm x 1.65mm). Both have 8pF load capacitance.

Q: Does packaging format affect substitution compatibility?

A: The FL3000037 is supplied in Tape & Reel (TR) format, while the 8Z-30.000MAAV-T is also TR and the XZAEECNANF-30.000000 is Cut Tape (CT). Packaging format does not affect electrical compatibility; selection depends on your procurement and assembly process requirements.

Q: Are all three parts RoHS compliant?

A: Yes. The FL3000037 and XZAEECNANF-30.000000 are ROHS3 compliant. The 8Z-30.000MAAV-T is RoHS compliant. All three meet environmental compliance standards for electronic component manufacturing.

Q: What is the significance of the 2pF load capacitance difference?

A: Load capacitance affects oscillator frequency accuracy and startup characteristics. The FL3000037 specifies 10pF while both substitutes specify 8pF. Your circuit design must accommodate this variation through appropriate load capacitor selection in the oscillator network. Verify your circuit design tolerates this parameter difference before substitution.

Q: Can I use the XZAEECNANF-30.000000 in place of the FL3000037 despite the higher ESR?

A: Yes, if your oscillator circuit design accommodates 100 Ohms ESR. Higher ESR may affect oscillator startup time and power consumption. Verify your circuit design specifications permit this ESR value before substitution.
