TZ0375A 32 MHz Crystal Equivalent & Substitute Parts

Part Overview

The TZ0375A is a 32 MHz fundamental mode quartz crystal manufactured by TST, designed for surface mount applications in 4-SMD, No Lead packaging. This component is classified as Active product status and is ROHS3 compliant. The crystal operates across a temperature range of -20°C to 70°C with frequency stability of ±10ppm, making it suitable for timing and clock generation circuits requiring precise frequency control.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across manufacturers, ensuring direct functional replacement without circuit redesign or performance degradation.

Substitute Part Grouping Explanation

Substitution eligibility for the TZ0375A is determined by strict equivalence across the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Frequency: 32 MHz
• Frequency Stability: ±10ppm
• Load Capacitance: 12pF
• ESR: 50 Ohms
• Operating Mode: Fundamental

Mechanical Parameters (Must Match Exactly):

• Package Type: 4-SMD, No Lead
• Dimensions: 3.20mm x 2.50mm
• Height - Seated (Max): 0.80mm
• Mounting Type: Surface Mount

Environmental & Compliance Parameters (Must Match Exactly):

• Operating Temperature Range: -20°C to 70°C
• RoHS Status: ROHS3 Compliant

All identified substitute parts maintain 100% equivalence across these parameters, enabling direct board-level replacement without modification to PCB layout, schematic design, or circuit operation.

Engineering Selection Recommendations

Primary Selection (TZ0375A - TST): The TZ0375A remains the primary component choice with 9,330 pieces in current inventory. Active product status confirms ongoing manufacturer support and supply chain availability. ROHS3 compliance satisfies environmental and regulatory requirements for commercial and industrial applications.

First Substitute (RH100-32.000-12-F-1010-TR - Raltron Electronics): The RH100-32.000-12-F-1010-TR offers the highest inventory availability at 3,771 pieces. This part maintains complete electrical and mechanical equivalence with the TZ0375A. Additional certifications include Moisture Sensitivity Level (MSL) 1 (Unlimited), REACH Unaffected status, and ECCN EAR99 classification, providing enhanced compliance documentation for regulated applications. Active product status ensures continued supply.

Second Substitute (QT325S-32.000MEEE-T - QST): The QT325S-32.000MEEE-T provides full parametric equivalence with 980 pieces available. This part includes MSL 1 (Unlimited) rating and HTSUS classification 8541.60.0060. Active product status confirms manufacturer support. Lower inventory levels make this option suitable for secondary sourcing or long-term supply diversification.

All three parts are suitable for direct substitution based on Active product status, ROHS3 compliance, and complete electrical and mechanical parameter equivalence.

Frequently Asked Questions (FAQ)

Q: Can the QT325S-32.000MEEE-T replace the TZ0375A on an existing PCB without modification?

A: Yes. Both parts share identical electrical parameters (32 MHz, ±10ppm stability, 12pF load capacitance, 50 Ohms ESR), mechanical dimensions (3.20mm x 2.50mm, 0.80mm height), and package type (4-SMD, No Lead). No PCB layout changes are required.

Q: What is the difference between the RH100-32.000-12-F-1010-TR and RH100-32.000-10-F-1010-TR?

A: The RH100-32.000-10-F-1010-TR variant differs in load capacitance (10pF instead of 12pF) and is not a direct substitute for the TZ0375A. Load capacitance affects circuit resonance frequency and must match the oscillator design specifications.

Q: Are all three substitute parts ROHS3 compliant?

A: Yes. The TZ0375A, QT325S-32.000MEEE-T, and RH100-32.000-12-F-1010-TR are all ROHS3 compliant, meeting environmental and regulatory requirements for commercial, industrial, and consumer applications.

Q: What does Moisture Sensitivity Level (MSL) 1 (Unlimited) mean?

A: MSL 1 indicates the component can be stored indefinitely without moisture absorption concerns. This classification applies to the RH100-32.000-12-F-1010-TR and QT325S-32.000MEEE-T, providing extended shelf life and simplified inventory management.

Q: Can these crystals operate outside the -20°C to 70°C temperature range?

A: No. All three parts are specified for operation within -20°C to 70°C. Operation outside this range may result in frequency drift beyond the ±10ppm stability specification and is not supported.

Q: Which substitute part should be selected for maximum inventory availability?

A: The RH100-32.000-12-F-1010-TR offers the highest current inventory at 3,771 pieces, followed by the TZ0375A at 9,330 pieces. The QT325S-32.000MEEE-T has the lowest availability at 980 pieces.
