Key Parameters

Substitute Part Grouping Explanation

The ECS-8FMX-330-TR qualifies as a substitute for the CPPC8-B6-33.0TS based on the following alignment of critical parameters:

Matching Parameters:

• Frequency: 33 MHz (identical)
• Output Type: CMOS (primary output, with additional TTL capability)
• Supply Voltage: 5V (identical)
• Function: Enable/Disable (identical)
• Mounting Type: Surface Mount (identical)
• Package / Case: 4-SOJ (identical form factor)
• RoHS Compliance: Both parts meet RoHS requirements

Allowable Variations:

• Frequency Stability: ECS-8FMX-330-TR operates at ±200ppm versus ±100ppm for the CPPC8-B6-33.0TS. This represents a wider tolerance band and is acceptable for applications where the original specification can accommodate this variance.
• Operating Temperature Range: ECS-8FMX-330-TR supports -40°C ~ 85°C versus 0°C ~ 70°C for the CPPC8-B6-33.0TS. The substitute provides extended temperature coverage.
• Current - Supply (Max): ECS-8FMX-330-TR draws 35mA versus 45mA for the CPPC8-B6-33.0TS. Lower current consumption is a favorable characteristic.
• Package Pitch: ECS-8FMX-330-TR uses 5.08mm pitch versus 7.62mm pitch for the CPPC8-B6-33.0TS. PCB layout modification is required.
• Moisture Sensitivity Level: ECS-8FMX-330-TR is MSL 1 (Unlimited) versus MSL 2 (1 Year) for the CPPC8-B6-33.0TS. The substitute offers superior moisture handling.

Parameter Comparison

Engineering Selection Recommendations

The ECS-8FMX-330-TR is an active product with current manufacturing support, making it suitable for replacing the obsolete CPPC8-B6-33.0TS. Both parts meet export compliance requirements (EAR99) and fall under the same HTSUS classification.

The substitute part offers improved compliance status (ROHS3 versus RoHS Compliant) and superior moisture handling characteristics (MSL 1 Unlimited versus MSL 2 1 Year). The extended operating temperature range (-40°C ~ 85°C) provides broader application coverage compared to the original part's 0°C ~ 70°C specification.

The primary design consideration is the package pitch difference: 5.08mm for the substitute versus 7.62mm for the original part. This requires PCB layout modification and footprint redesign. The frequency stability specification of ±200ppm for the substitute is wider than the original ±100ppm; applications must confirm this tolerance is acceptable for their frequency accuracy requirements.

Frequently Asked Questions (FAQ)

Q: Can the ECS-8FMX-330-TR be used as a direct drop-in replacement for the CPPC8-B6-33.0TS?

A: No. While both parts are 4-SOJ surface mount oscillators with identical frequency and supply voltage, the package pitch differs (5.08mm versus 7.62mm). PCB layout modification is required. The parts cannot be used interchangeably on the same printed circuit board without redesign.

Q: What is the impact of the ±200ppm frequency stability on the ECS-8FMX-330-TR compared to the ±100ppm of the original part?

A: The substitute part has a wider frequency tolerance band. Applications requiring frequency accuracy within ±100ppm must evaluate whether ±200ppm meets their system requirements. This is a critical parameter for timing-sensitive applications and must be verified during design review.

Q: Are there any compliance or certification differences between these parts?

A: Both parts are RoHS compliant and carry the same ECCN and HTSUS classifications. The ECS-8FMX-330-TR carries ROHS3 compliance, which represents a more recent revision of the RoHS standard. The substitute also includes REACH Unaffected status, providing additional regulatory clarity.

Q: What are the advantages of the ECS-8FMX-330-TR regarding moisture sensitivity?

A: The substitute part is MSL 1 (Unlimited moisture sensitivity level) compared to MSL 2 (1 Year) for the original part. MSL 1 provides indefinite shelf life without moisture bake-out requirements, simplifying inventory management and reducing component preparation time before assembly.

Q: Does the lower current consumption of the ECS-8FMX-330-TR provide any system-level benefits?

A: The substitute draws 35mA maximum supply current versus 45mA for the original part. This 10mA reduction may provide marginal benefits in power budget-constrained applications, though the impact is typically minimal in most 5V oscillator applications.

Q: What is the significance of the extended operating temperature range of the ECS-8FMX-330-TR?

A: The substitute supports -40°C ~ 85°C versus 0°C ~ 70°C for the original part. This extended range allows deployment in industrial, automotive, or environmental applications requiring operation beyond the original part's temperature limits.
