Substitute Part Grouping Explanation

Substitute parts are grouped into two categories based on electrical and mechanical compatibility with the YNETHE125:

Category 1: Direct Electrical Equivalents (Skyworks Solutions Si550 and Si595 Series)

• 550CC125M000DGR, 550CD125M000DGR, 550CF125M000DGR, 595CC125M000DGR

These parts match all critical electrical parameters: 125 MHz frequency, 3.3V supply, CMOS output, ±50ppm frequency stability, Enable/Disable function, and identical package/case specifications. All are active products from Skyworks Solutions. Differences exist in Absolute Pull Range (APR) values (±150ppm, ±80ppm, ±100ppm, ±130ppm respectively) and maximum supply current (98mA or 100mA versus 20mA in the original). Physical dimensions are identical in length and width; height is 0.071" (1.80mm) versus 0.061" (1.55mm) for the original.

Category 2: Pin-Compatible Alternatives (Suntsu Electronics SVC75C Series)

• SVC75C3A48C2-125.000M, SVC75C3A48D2-125.000M

These parts match all critical electrical parameters: 125 MHz frequency, 3.3V supply, CMOS output, ±50ppm frequency stability and APR, Enable/Disable function, and identical package/case specifications. Both are active products from Suntsu Electronics. Maximum supply current is 25mA (higher than the original 20mA but lower than Skyworks alternatives). Physical dimensions are identical in length and width; height is 0.067" (1.70mm) versus 0.061" (1.55mm) for the original.

Key Parameters Determining Substitution:

• Frequency: 125 MHz (exact match required)
• Voltage Supply: 3.3V (exact match required)
• Output Type: CMOS (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Function: Enable/Disable (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Operating Temperature: -40°C ~ 85°C (exact match required)

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed are active products with established supply chains, addressing the obsolescence of the YNETHE125.

Suntsu Electronics SVC75C Series (SVC75C3A48C2-125.000M, SVC75C3A48D2-125.000M) are recommended as primary substitutes. These parts maintain identical electrical specifications to the original (±50ppm APR, 25mA maximum supply current) and offer the closest physical compatibility with a maximum seated height of 0.067" (1.70mm), only 0.006" higher than the original. Both parts carry ROHS3 compliance certification.

Skyworks Solutions Si550 Series (550CC125M000DGR, 550CD125M000DGR, 550CF125M000DGR) and Si595 Series (595CC125M000DGR) are functionally compatible alternatives. These parts maintain all critical electrical specifications but feature higher maximum supply current (98mA or 100mA) and greater maximum seated height (0.071" or 1.80mm), representing a 0.010" increase over the original. Selection among these three Si550 variants depends on application-specific pull range requirements: 550CC125M000DGR (±150ppm APR), 550CD125M000DGR (±80ppm APR), or 550CF125M000DGR (±100ppm APR).

Frequently Asked Questions (FAQ)

Q: Can the SVC75C3A48C2-125.000M and SVC75C3A48D2-125.000M be used interchangeably with the YNETHE125?

A: Yes. Both parts match all critical electrical parameters (125 MHz frequency, 3.3V supply, CMOS output, ±50ppm frequency stability and APR, Enable/Disable function) and package specifications (6-SMD, No Lead, 7.00mm x 5.00mm footprint). The maximum seated height difference of 0.006" (0.067" versus 0.061") is within typical PCB assembly tolerances for surface mount components.

Q: What is the difference between the Skyworks Si550 variants (550CC, 550CD, 550CF)?

A: All three Si550 variants share identical frequency (125 MHz), voltage supply (3.3V), output type (CMOS), frequency stability (±50ppm), and package specifications. The primary difference is the Absolute Pull Range (APR): 550CC125M000DGR offers ±150ppm, 550CD125M000DGR offers ±80ppm, and 550CF125M000DGR offers ±100ppm. Selection depends on the tuning range required by the application circuit.

Q: Are there compliance differences between substitute options?

A: The Suntsu Electronics SVC75C series parts carry ROHS3 compliance certification. The Skyworks Solutions parts do not specify RoHS status in the provided data. The original YNETHE125 is RoHS Compliant. All parts are classified under ECCN EAR99 and HTSUS 8542.39.0001.

Q: What is the impact of higher supply current in Skyworks alternatives?

A: Skyworks Si550 and Si595 series parts specify maximum supply current of 98mA or 100mA, compared to 20mA for the YNETHE125 and 25mA for Suntsu alternatives. This difference reflects different internal circuit design and does not affect functional compatibility. Power supply design must accommodate the higher current draw of Skyworks parts.

Q: Are all substitute parts available in the same packaging format?

A: Suntsu Electronics parts (SVC75C3A48C2-125.000M, SVC75C3A48D2-125.000M) are supplied in Bulk packaging. Skyworks Solutions parts (550CC125M000DGR, 550CD125M000DGR, 550CF125M000DGR, 595CC125M000DGR) are supplied in Tape & Reel (TR) packaging. Both packaging formats are suitable for automated PCB assembly.

Q: What is the maximum height constraint for PCB assembly?

A: The original YNETHE125 has a maximum seated height of 0.061" (1.55mm). Suntsu alternatives are 0.067" (1.70mm), and Skyworks alternatives are 0.071" (1.80mm). Height differences must be evaluated against specific PCB design constraints, including clearance to adjacent components and conformal coating requirements.
