Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the FD2500063 are qualified based on the following critical 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)
• Size / Dimension: 0.197" L x 0.126" W (5.00mm x 3.20mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Acceptable variations within substitution:

• Frequency Stability: ±20ppm to ±50ppm (tighter or equivalent tolerance acceptable)
• Operating Temperature Range: -40°C ~ 85°C or -20°C ~ 70°C (both acceptable for general applications)
• Current - Supply (Max): 15mA to 16mA (minor variation acceptable)
• Height - Seated (Max): 0.051" (1.30mm) to 0.055" (1.40mm) (minor variation acceptable)

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the FD2500063. Selection among qualified substitutes depends on application-specific requirements:

FD2500053 offers tighter frequency stability at ±20ppm but operates within a narrower temperature range (-20°C ~ 70°C). This part is suitable for controlled environment applications where extended temperature performance is not required.

FD2500054 provides the widest frequency stability tolerance at ±50ppm and maintains the full operating temperature range (-40°C ~ 85°C) matching the FD2500063. This part accommodates applications with less stringent frequency accuracy requirements.

FD2500061 combines ±25ppm frequency stability with a narrower operating temperature range (-20°C ~ 70°C), offering a middle-ground option for moderate temperature environments.

SXO53C3C481-25.000M from Suntsu Electronics provides equivalent electrical performance with ±25ppm stability and full temperature range (-40°C ~ 85°C). The maximum seated height is 0.055" (1.40mm), which is 0.004" taller than the FD2500063. This minor dimensional difference is acceptable for most PCB layouts but should be verified for space-constrained applications. Current supply is specified at 16mA maximum, 1mA higher than the primary part.

Frequently Asked Questions (FAQ)

Q: Can FD2500053 replace FD2500063 in all applications?

A: FD2500053 is electrically compatible but operates within -20°C ~ 70°C temperature range versus -40°C ~ 85°C for FD2500063. Use FD2500053 only in applications where the narrower temperature range is acceptable.

Q: What is the difference between FD2500054 and FD2500063?

A: FD2500054 has a wider frequency stability tolerance (±50ppm versus ±25ppm) but maintains identical temperature range, package, and electrical interface. Use FD2500054 when frequency accuracy is less critical.

Q: Is SXO53C3C481-25.000M from a different manufacturer compatible?

A: Yes. SXO53C3C481-25.000M meets all critical electrical and mechanical parameters. The 0.004" height difference and 1mA higher current specification are within acceptable tolerances for standard applications.

Q: Do all substitute parts have the same package footprint?

A: All parts use 4-SMD, No Lead package with 5.00mm x 3.20mm footprint. SXO53C3C481-25.000M has a maximum seated height of 0.055" (1.40mm) versus 0.051" (1.30mm) for Diodes parts. Verify clearance in height-constrained designs.

Q: Which substitute offers the best frequency stability?

A: FD2500053 provides the tightest frequency stability at ±20ppm. However, this part operates only to 70°C maximum. For applications requiring both tight stability and full temperature range, FD2500063, FD2500061, or SXO53C3C481-25.000M at ±25ppm are appropriate.

Q: Are all parts ROHS3 compliant?

A: Yes. All listed parts are ROHS3 compliant. Moisture sensitivity level is MSL 1 (Unlimited) for all Diodes parts. SXO53C3C481-25.000M does not specify MSL but is suitable for standard handling and storage.
