Engineering Selection Recommendations

FD2500053 (Diodes Incorporated - Upgrade Option) FD2500053 is functionally equivalent to FD2500061 with improved frequency stability of ±20ppm versus ±25ppm. Operating temperature range remains -20°C ~ 70°C. All electrical and mechanical parameters are identical. This part is suitable for applications requiring tighter frequency tolerance while maintaining the same thermal operating envelope. RoHS3 compliance and MSL 1 rating are maintained.

FD2500054 (Diodes Incorporated - Extended Temperature Option) FD2500054 provides extended operating temperature range of -40°C ~ 85°C compared to the original -20°C ~ 70°C specification. Frequency stability is ±50ppm, which is relaxed relative to FD2500061. This part is suitable for applications requiring wider temperature operation but with less stringent frequency stability requirements. All other electrical and mechanical parameters match. RoHS3 compliance and MSL 1 rating are maintained.

FD2500063 (Diodes Incorporated - Premium Option) FD2500063 combines the frequency stability of FD2500061 (±25ppm) with the extended temperature range of FD2500054 (-40°C ~ 85°C). This represents the highest specification variant within the Diodes Incorporated FD series for this frequency. Suitable for applications requiring both tight frequency tolerance and wide temperature operation. RoHS3 compliance and MSL 1 rating are maintained.

SXO53C3C271-25.000M (Suntsu Electronics - Cross-Manufacturer Alternative) SXO53C3C271-25.000M is a cross-manufacturer substitute from Suntsu Electronics with identical frequency, output type, supply voltage, and frequency stability (±25ppm). Physical dimensions are compatible with 0.1mm additional height (1.40mm vs 1.30mm maximum). Maximum supply current is 16mA versus 15mA. Disable mode current specification is not provided. This part is suitable for applications where Suntsu sourcing is preferred or where Diodes Incorporated parts are unavailable. RoHS3 compliance is maintained. Verify disable mode current requirements before selection if low-power standby operation is critical.

Frequently Asked Questions (FAQ)

Q: Can FD2500054 replace FD2500061 in all applications? A: FD2500054 is mechanically and electrically compatible but has relaxed frequency stability (±50ppm vs ±25ppm) and extended temperature range (-40°C ~ 85°C vs -20°C ~ 70°C). It is suitable for applications where the original -20°C ~ 70°C temperature range and ±25ppm stability are not required. Verify your application's frequency tolerance and temperature requirements before substitution.

Q: What is the difference between FD2500053 and FD2500063? A: Both parts are from Diodes Incorporated with identical frequency stability (±20ppm and ±25ppm respectively). The key difference is operating temperature range: FD2500053 operates -20°C ~ 70°C (matching FD2500061), while FD2500063 operates -40°C ~ 85°C (extended range). Select FD2500063 if your application requires operation below -20°C or above 70°C.

Q: Is SXO53C3C271-25.000M a direct replacement for FD2500061? A: SXO53C3C271-25.000M is functionally compatible with matching frequency, output type, supply voltage, and frequency stability. Physical height is 0.1mm greater (1.40mm vs 1.30mm maximum). Maximum supply current is 1mA higher (16mA vs 15mA). Disable mode current is not specified for the Suntsu part. Verify PCB layout clearance and power budget before substitution.

Q: Are all substitute parts RoHS3 compliant? A: Yes. All listed substitute parts (FD2500053, FD2500054, FD2500063, and SXO53C3C271-25.000M) are RoHS3 compliant and maintain MSL 1 moisture sensitivity rating, ensuring compliance with environmental and regulatory requirements.

Q: Which substitute part has the best frequency stability? A: FD2500053 offers the tightest frequency stability at ±20ppm. FD2500061, FD2500063, and SXO53C3C271-25.000M all specify ±25ppm. FD2500054 has the most relaxed specification at ±50ppm.

Q: Can I use FD2500063 in place of FD2500061 without design changes? A: Yes. FD2500063 is a direct mechanical and electrical substitute with identical package, footprint, and pin configuration. It provides equal or superior specifications (same frequency stability, extended temperature range). No design changes are required.
