Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M-32.000MBBK-T is determined by strict equivalence across the following parameters:

Critical Matching Parameters:

• Frequency: 32.0000 MHz (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Load Capacitance: 20pF (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 3.20mm L x 2.50mm W x 0.80mm H max (exact match required)
• Operating Temperature Range: -20°C to 70°C (exact match required)

Allowable Variation Parameters:

• ESR (Equivalent Series Resistance): Variation permitted within component design specifications
• Manufacturer: Different manufacturers acceptable if all critical parameters match
• Series designation: May differ between manufacturers
• RoHS compliance version: Both RoHS3 and equivalent standards acceptable

The ECS-320-20-33-TR meets all critical matching parameters and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: 7M-32.000MBBK-T

The TXC CORPORATION 7M-32.000MBBK-T is the specified component with active product status and RoHS compliance. Selection of this part is appropriate when TXC supply chain availability is confirmed and ESR specification of 60 Ohms is required by circuit design.

Substitute Part: ECS-320-20-33-TR

The ECS Inc. ECS-320-20-33-TR qualifies as a direct substitute based on matching all critical electrical and mechanical parameters. This part is actively produced with ROHS3 compliance and offers lower ESR (40 Ohms versus 60 Ohms). The lower ESR may provide improved oscillator startup characteristics and reduced power consumption in certain circuit topologies. Selection of this substitute is appropriate when:

• TXC supply is unavailable or lead times exceed project requirements
• Circuit design permits ESR variation within the 40-60 Ohm range
• ECS Inc. supply chain offers better availability or cost efficiency
• ROHS3 compliance is preferred over standard RoHS compliance

Both parts are suitable for identical PCB footprints and assembly processes due to matching package dimensions and mounting specifications.

Frequently Asked Questions (FAQ)

Q: Can the ECS-320-20-33-TR be used as a direct replacement for the 7M-32.000MBBK-T?

A: Yes. The ECS-320-20-33-TR meets all critical substitution parameters: identical frequency (32.0000 MHz), frequency stability (±50ppm), load capacitance (20pF), package type (4-SMD, No Lead), physical dimensions (3.20 x 2.50 x 0.80mm), and operating temperature range (-20°C to 70°C). The parts are electrically and mechanically interchangeable.

Q: What is the difference in ESR between these parts?

A: The 7M-32.000MBBK-T has 60 Ohms ESR, while the ECS-320-20-33-TR has 40 Ohms ESR. Lower ESR generally results in faster oscillator startup and lower power consumption. Circuit designs must verify that the oscillator circuit can operate with ESR values in the 40-60 Ohm range.

Q: Are both parts RoHS compliant?

A: Yes. The 7M-32.000MBBK-T is RoHS Compliant, and the ECS-320-20-33-TR is ROHS3 Compliant. Both meet environmental compliance requirements for modern electronic equipment.

Q: Do these parts have the same physical footprint?

A: Yes. Both parts use identical 4-SMD, No Lead packaging with dimensions of 3.20mm length x 2.50mm width x 0.80mm maximum height. PCB footprints and assembly processes are identical.

Q: What is the Moisture Sensitivity Level for both parts?

A: Both parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.

Q: Can I use these parts interchangeably in production?

A: Yes, provided your circuit design has been verified to operate with ESR values between 40 and 60 Ohms. Both parts meet identical frequency, stability, load capacitance, and package specifications. Confirm oscillator circuit performance with the lower ESR value of the ECS substitute before full production transition.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -20°C to 70°C. This range must match your application's environmental requirements.
