Key Parameters

Substitute Part Grouping Explanation

Substitution of the CPPFXC8-A7BR-16.0TS is determined by the following critical parameters:

• Frequency Match: 16 MHz (exact match required)
• Output Type: CMOS (primary requirement)
• Supply Voltage: 5V (exact match required)
• Function: Enable/Disable capability (required)
• Operating Temperature Range: -40°C ~ 85°C (minimum requirement)
• Mounting Type: Surface Mount (required)
• Package Type: 4-SOJ configuration (required for PCB compatibility)

The ECS-8FMX-160-TR meets all critical substitution criteria. While it features a different pitch specification (5.08mm vs. 7.62mm) and enhanced frequency stability (±200ppm vs. ±25ppm), these represent improvements in performance and dimensional compatibility. The substitute part maintains identical frequency, supply voltage, enable/disable function, and operating temperature range.

Engineering Selection Recommendations

The ECS-8FMX-160-TR is the qualified substitute for the CPPFXC8-A7BR-16.0TS based on the following engineering criteria:

Functional Equivalence: Both parts operate at 16 MHz with 5V supply and enable/disable functionality, meeting core oscillator requirements.

Compliance Status: The ECS-8FMX-160-TR holds active product status with ROHS3 compliance, compared to the obsolete status of the original part. This ensures long-term availability and regulatory alignment.

Performance Characteristics: The substitute part delivers lower maximum supply current (23mA vs. 45mA), representing improved power efficiency. The frequency stability specification of ±200ppm is within acceptable tolerance for standard timing applications.

Environmental Specifications: The ECS-8FMX-160-TR features MSL 1 with unlimited shelf life, compared to MSL 2 with 1-year shelf life for the original part, providing superior moisture handling and storage flexibility.

Physical Compatibility: Both parts maintain identical height (0.185" maximum seated height) and similar overall dimensions. The pitch difference (5.08mm vs. 7.62mm) requires PCB layout verification but does not affect functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the ECS-8FMX-160-TR directly replace the CPPFXC8-A7BR-16.0TS without PCB modification?

A: The substitute part maintains the same 4-SOJ package type and identical seated height. However, the pitch specification differs (5.08mm vs. 7.62mm), requiring PCB footprint verification. Physical dimensions are comparable (14.00mm x 8.65mm vs. 14.50mm x 8.80mm), but pad spacing must be confirmed for direct substitution.

Q: What is the significance of the frequency stability difference (±25ppm vs. ±200ppm)?

A: The original part specifies ±25ppm frequency stability, while the substitute specifies ±200ppm. For applications requiring tighter frequency tolerance, this difference must be evaluated against system timing requirements. The substitute remains suitable for standard 16 MHz oscillator applications.

Q: Why does the substitute part have lower supply current (23mA vs. 45mA)?

A: The ECS-8FMX-160-TR demonstrates improved power efficiency in its design. This represents a performance advantage and does not affect functional compatibility, as the substitute operates within the same 5V supply specification.

Q: What does the MSL rating difference mean for component handling?

A: The original part carries MSL 2 (1 Year), requiring controlled storage conditions. The substitute carries MSL 1 (Unlimited), indicating superior moisture resistance and indefinite shelf life under standard conditions. This simplifies inventory management and reduces risk of moisture-related failures.

Q: Are there output compatibility differences between CMOS and CMOS/TTL?

A: The substitute part supports both CMOS and TTL output modes, while the original specifies CMOS only. This represents enhanced functionality and maintains full compatibility with CMOS-based receiver circuits.

Q: What is the impact of the product status change from Obsolete to Active?

A: The substitute part's active status ensures continued manufacturing, availability, and technical support. The original part's obsolete status limits future procurement options, making the active substitute essential for long-term system support.
