Substitute Part Grouping Explanation

Substitution of the FD2500058 is determined by strict equivalence in the following parameters:

Frequency: 25 MHz (exact match required)
Output Type: CMOS (exact match required)
Supply Voltage: 3.3V (exact match required)
Function: Enable/Disable (exact match required)
Package / Case: 4-SMD, No Lead (exact match required)
Mounting Type: Surface Mount (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

Variations in Frequency Stability (±20ppm, ±25ppm, ±50ppm), Operating Temperature range (-20°C ~ 70°C or -40°C ~ 85°C), Current Supply (Max) (15mA or 16mA), and Height - Seated (Max) (1.30mm or 1.40mm) are permitted within the substitute parts listed, as these parameters do not affect functional interchangeability in standard applications.

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring continued availability and regulatory conformance. Selection among substitutes depends on application-specific requirements:

FD2500053 and FD2500061 are suitable for applications requiring tighter frequency stability (±20ppm and ±25ppm respectively) within the standard operating temperature range (-20°C ~ 70°C).

FD2500063 and FD2500054 extend the operating temperature range to -40°C ~ 85°C, accommodating industrial and extended-temperature applications. FD2500054 is designated as manufacturer recommended and maintains ±50ppm frequency stability matching the original FD2500058.

SXO53C3A271-25.000M from Suntsu Electronics provides cross-manufacturer compatibility with equivalent electrical specifications. Maximum supply current is 16mA versus 15mA for Diodes Incorporated parts, and seated height is 1.40mm versus 1.30mm. These dimensional and current variations remain within acceptable tolerances for standard PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can FD2500053 replace FD2500058 directly?

A: Yes. FD2500053 is electrically and mechanically compatible. It provides improved frequency stability (±20ppm versus ±50ppm) while maintaining identical package dimensions, supply voltage, and operating temperature range.

Q: What is the difference between FD2500054 and FD2500058?

A: Both parts share identical frequency stability (±50ppm), supply voltage (3.3V), and package specifications. FD2500054 extends the operating temperature range to -40°C ~ 85°C, making it suitable for industrial applications. FD2500054 is manufacturer recommended.

Q: Can SXO53C3A271-25.000M be used as a substitute?

A: Yes. SXO53C3A271-25.000M from Suntsu Electronics is functionally equivalent. The maximum supply current is 1mA higher (16mA versus 15mA) and seated height is 0.10mm greater (1.40mm versus 1.30mm). These variations are compatible with standard PCB designs.

Q: Does operating temperature range affect substitution?

A: Operating temperature range does not prevent substitution. Parts with extended ranges (-40°C ~ 85°C) are suitable replacements for standard-range applications (-20°C ~ 70°C). Application requirements determine whether extended range is necessary.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant, maintaining regulatory compliance equivalent to the original FD2500058.

Q: What determines if a part can substitute for FD2500058?

A: Substitution requires exact equivalence in frequency (25 MHz), output type (CMOS), supply voltage (3.3V), function (Enable/Disable), package type (4-SMD, No Lead), and mounting method (Surface Mount). Frequency stability, operating temperature, and current specifications may vary within the listed alternatives.
