TZ3375C 32 MHz Crystal Equivalent & Substitute Parts

Part Overview

The TZ3375C is a 32 MHz fundamental mode crystal oscillator manufactured by TST, designed for surface mount applications in compact form factors. This part is specified as a 4-SMD, No Lead package with 6pF load capacitance and 50 Ohms equivalent series resistance. The component is actively produced and ROHS3 compliant, suitable for applications requiring precise frequency reference in the 32 MHz range with ±10ppm tolerance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility are maintained across all critical parameters. Alternative sources provide design flexibility, supply chain redundancy, and procurement optimization without requiring circuit redesign.

Engineering Selection Recommendations

All three parts—TZ3375C, ABM11W-32.0000MHZ-6-D1X-T3, and ECS-320-6-37B-CTN-TR3—are functionally equivalent for direct substitution in 32 MHz crystal applications. Selection criteria are based on:

Product Status: All parts are actively manufactured and supported by their respective suppliers.

Regulatory Compliance: All parts meet ROHS3 requirements and are classified under identical ECCN (EAR99) and HTSUS (8541.60.0060) codes, ensuring consistent export and import compliance.

Supply Availability: Current inventory levels are 3925 units (TZ3375C), 4959 units (ABM11W-32.0000MHZ-6-D1X-T3), and 1719 units (ECS-320-6-37B-CTN-TR3). Selection may be influenced by procurement lead times and supplier relationships.

Moisture Sensitivity: TZ3375C and ECS-320-6-37B-CTN-TR3 specify MSL 1 (Unlimited). ABM11W-32.0000MHZ-6-D1X-T3 lists MSL as Not Applicable. Both conditions are compatible with standard surface mount assembly processes.

Mechanical Compatibility: Identical package dimensions and mounting characteristics ensure direct PCB footprint compatibility without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can ABM11W-32.0000MHZ-6-D1X-T3 replace TZ3375C without circuit modification?

A: Yes. Both parts share identical electrical specifications (32 MHz, ±10 ppm tolerance, 6 pF load capacitance, 50 Ohms ESR) and mechanical dimensions (2.00 x 1.60 mm, 4-SMD No Lead package). No circuit redesign is required.

Q: Are there differences in moisture sensitivity between the substitute parts?

A: TZ3375C and ECS-320-6-37B-CTN-TR3 specify MSL 1 (Unlimited moisture sensitivity). ABM11W-32.0000MHZ-6-D1X-T3 lists MSL as Not Applicable. Both conditions are compatible with standard automated assembly and storage protocols.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. All parts are ROHS3 compliant and classified under identical ECCN (EAR99) and HTSUS (8541.60.0060) codes. They are suitable for equivalent regulatory and export documentation.

Q: What is the operating temperature range for these crystals?

A: All three parts operate across -40°C to 85°C. Frequency stability is specified as ±20 ppm across this range, with frequency tolerance of ±10 ppm at nominal conditions.

Q: Are these parts suitable for automated pick-and-place assembly?

A: Yes. All parts are supplied in Tape & Reel (TR) packaging format, standard for automated surface mount assembly equipment. Physical dimensions and package type are identical across all three parts.

Q: What is the load capacitance specification, and why is it important?

A: Load capacitance is specified as 6 pF for all three parts. This parameter defines the capacitive load presented by the oscillator circuit and must match the crystal specification to maintain frequency accuracy and stability.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical electrical parameters, package dimensions, and operating characteristics enable direct substitution. No PCB layout changes or circuit modifications are necessary.
