Key Parameters

Substitute Part Grouping Explanation

Substitution for the SG-615PCG 2.0000MM is determined by the following critical parameters:

• Frequency: 2 MHz (exact match required)
• Output Type: CMOS, TTL (exact match required)
• Package / Case: 4-SOJ, 5.08mm pitch (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Function: Enable/Disable (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)

The ECS-8FMX-020-TR qualifies as a substitute part based on matching all critical parameters. Variations in supply voltage (3.3V vs. 5V), frequency stability (±100ppm vs. ±200ppm), and maximum supply current (28mA vs. 23mA) are within acceptable tolerance ranges for this oscillator category and do not prevent functional substitution in most applications.

Parameter Comparison

Engineering Selection Recommendations

The ECS-8FMX-020-TR serves as a functional substitute for the obsolete SG-615PCG 2.0000MM based on matching package geometry, frequency, output type, and operating temperature range. Both parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring environmental and regulatory compatibility.

The primary design consideration is the supply voltage difference: the SG-615PCG operates at 3.3V while the ECS-8FMX-020-TR operates at 5V. Circuit designs must accommodate this voltage requirement. The ECS-8FMX-020-TR exhibits wider frequency stability (±200ppm vs. ±100ppm) and lower maximum supply current (23mA vs. 28mA), both of which are generally favorable characteristics for most applications.

The ECS-8FMX-020-TR is classified as "Not For New Designs," indicating limited long-term availability. For new product development, consultation with component suppliers for current-generation 2 MHz oscillators in 4-SOJ packaging is recommended.

Frequently Asked Questions (FAQ)

Q: Can the ECS-8FMX-020-TR directly replace the SG-615PCG 2.0000MM in existing designs?

A: Direct replacement is possible from a mechanical and functional standpoint due to identical package geometry, pin configuration, and frequency output. However, the supply voltage difference (5V vs. 3.3V) requires circuit verification to ensure the receiving circuit can tolerate or regulate to the higher voltage.

Q: What is the significance of the frequency stability difference (±100ppm vs. ±200ppm)?

A: The SG-615PCG offers tighter frequency tolerance. The ECS-8FMX-020-TR's wider tolerance may be acceptable for applications with less stringent timing requirements. Applications requiring precise frequency control should evaluate whether the ±200ppm specification meets system specifications.

Q: Are both parts pin-compatible?

A: Yes. Both parts use the 4-SOJ package with 5.08mm pitch and identical physical dimensions (0.551" L x 0.341" W, 4.70mm height), ensuring mechanical and electrical pin compatibility on the PCB.

Q: Why are both parts classified with limited availability status?

A: The SG-615PCG is Obsolete, and the ECS-8FMX-020-TR is Not For New Designs. Both classifications indicate reduced manufacturing and distribution support. For applications requiring long-term component availability, alternative current-generation 2 MHz oscillators should be evaluated.

Q: Does the lower supply current of the ECS-8FMX-020-TR affect performance?

A: The lower maximum supply current (23mA vs. 28mA) indicates improved power efficiency and does not negatively impact oscillator performance. This characteristic is generally beneficial for power-constrained applications.
