Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FL3200038Z is determined by the following critical parameters:

Primary Matching Criteria (Non-Negotiable):

• Frequency: 32 MHz
• Frequency Stability: ±10ppm
• Frequency Tolerance: ±10ppm
• Operating Mode: Fundamental
• Operating Temperature Range: -20°C to 75°C
• Mounting Type: Surface Mount
• Package / Case: 4-SMD, No Lead
• RoHS Status: ROHS3 Compliant
• MSL Rating: 1 (Unlimited)

Secondary Variation Parameters (Allowable Differences):

• Load Capacitance: 8pF to 12pF range
• ESR (Equivalent Series Resistance): 40 to 60 Ohms range
• Physical Dimensions: Variations within 4-SMD, No Lead package envelope
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®

The three identified substitute parts meet all primary matching criteria. Variations in load capacitance and ESR fall within acceptable design tolerances for 32 MHz crystal applications. Physical dimension differences reflect different package footprints within the 4-SMD, No Lead category.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain Active product status and ROHS3 compliance with MSL 1 (Unlimited) ratings, matching the regulatory and environmental requirements of the FL3200038Z.

TSX-3225 32.0000MF10Z-W6 (EPSON) provides the closest electrical and mechanical alignment to the FL3200038Z. Both components feature identical 40 Ohms ESR, matching frequency and stability specifications, and identical 3.20mm × 2.50mm footprint dimensions. The TSX-3225 variant operates within the same temperature range and maintains equivalent compliance certifications. This substitute is suitable for direct replacement in applications where the original footprint and ESR characteristics are design constraints.

FA-128 32.0000MF10Z-W3 (EPSON) matches all frequency and stability parameters with a 12pF load capacitance and 60 Ohms ESR. The component uses a smaller 2.00mm × 1.60mm footprint with reduced maximum seated height of 0.50mm. This variant is applicable in space-constrained designs where the smaller package envelope provides layout advantages. The increased ESR and load capacitance represent acceptable variations for 32 MHz crystal applications.

FA-128 32.0000MF10Z-AJ3 (EPSON) operates at 8pF load capacitance with 60 Ohms ESR in the same compact 2.00mm × 1.60mm package. This variant is suitable for applications requiring the smallest available footprint while maintaining frequency and stability specifications. The lower load capacitance may be advantageous in certain circuit topologies.

All three substitutes are available in Active status with substantial inventory levels, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the FA-128 32.0000MF10Z-AJ3 with 8pF load capacitance replace the FL3200038Z with 10pF load capacitance?

A: Yes. The 8pF load capacitance falls within the acceptable variation range for 32 MHz crystal substitution. Both components operate at identical frequency (32 MHz) and frequency stability (±10ppm). The 2pF difference in load capacitance is a standard design tolerance in crystal oscillator applications. Circuit design verification is required to confirm compatibility with the specific oscillator circuit topology.

Q: What are the physical footprint differences between the substitute parts?

A: The FL3200038Z and TSX-3225 32.0000MF10Z-W6 share identical 3.20mm × 2.50mm dimensions, enabling direct PCB footprint compatibility. The FA-128 variants (both AJ3 and W3) use a smaller 2.00mm × 1.60mm footprint. The FA-128 components also feature reduced maximum seated heights (0.50mm versus 0.75mm for the FL3200038Z). Footprint selection depends on available PCB space and design layout requirements.

Q: How do ESR differences affect crystal performance?

A: The FL3200038Z operates at 40 Ohms ESR, while the FA-128 variants operate at 60 Ohms ESR. The TSX-3225 maintains 40 Ohms ESR matching the original part. ESR affects crystal startup time and power consumption in oscillator circuits. The 20 Ohms difference between 40 and 60 Ohms represents a standard variation within 32 MHz crystal design specifications. Circuit-level analysis is required to determine if the higher ESR of the FA-128 variants impacts oscillator performance in the specific application.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All three substitute parts carry ROHS3 compliance certification with MSL 1 (Unlimited) moisture sensitivity ratings, matching the regulatory status of the FL3200038Z. All components are suitable for applications requiring ROHS3 compliance.

Q: What packaging formats are available for each substitute?

A: The FL3200038Z and TSX-3225 32.0000MF10Z-W6 are supplied in Tape & Reel (TR) format. The FA-128 32.0000MF10Z-AJ3 is supplied in Tape & Reel (TR) format. The FA-128 32.0000MF10Z-W3 is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly process requirements and volume specifications.

Q: Do all substitute parts operate within the same temperature range?

A: Yes. All substitute parts operate across the -20°C to 75°C temperature range, matching the FL3200038Z operating temperature specification. All components are suitable for applications requiring this temperature range.
