Substitute Part Grouping Explanation

Substitution eligibility for the FN2500169 is determined by strict equivalence across 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: 0.276" L x 0.197" W (7.00mm x 5.00mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

Substitute parts are grouped into the following categories based on their relationship to the main part:

Upgrade Substitutes: Parts with improved specifications (tighter frequency stability, extended operating temperature range) while maintaining all critical electrical and mechanical parameters.

Manufacturer Recommended Substitutes: Parts from the same manufacturer offering equivalent or enhanced performance with full compatibility.

Direct Manufacturer Alternatives: Parts from alternative manufacturers meeting identical electrical and mechanical specifications.

Packaging Variants: Parts with identical electrical specifications but different packaging configurations (Bulk vs. Tape & Reel).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, ensuring regulatory alignment with the FN2500169.

FN2500171 provides improved frequency stability (±25ppm vs. ±50ppm) and extended operating temperature range (-40°C ~ 85°C vs. -20°C ~ 70°C) while maintaining identical electrical and mechanical specifications. This part is suitable for applications requiring tighter frequency tolerance or operation across wider temperature extremes.

FN2500161 offers extended operating temperature range (-40°C ~ 85°C) with equivalent frequency stability (±50ppm) and is manufacturer recommended. This part accommodates applications requiring broader temperature operation without sacrificing frequency accuracy.

FNETHE025 provides improved frequency stability (±25ppm) in Tape & Reel packaging with reduced seated height (0.061" vs. 0.071"). This variant is suitable for high-volume production environments and applications with height constraints.

SXO75C3A271-25.000M from Suntsu Electronics maintains equivalent electrical specifications with maximum supply current of 16mA (vs. 15mA) and reduced seated height (0.063" vs. 0.071"). This cross-manufacturer alternative is suitable for applications where alternative sourcing is required.

Frequently Asked Questions (FAQ)

Q: Can FN2500171 replace FN2500169 in all applications?

A: FN2500171 is electrically and mechanically compatible with FN2500169. The improved frequency stability (±25ppm vs. ±50ppm) and extended operating temperature range (-40°C ~ 85°C vs. -20°C ~ 70°C) make it suitable for applications requiring these enhanced specifications. Existing designs using FN2500169 will function with FN2500171 without modification.

Q: What is the difference between FN2500161 and FN2500171?

A: Both parts offer extended operating temperature range (-40°C ~ 85°C). FN2500171 provides tighter frequency stability (±25ppm vs. ±50ppm). FN2500161 maintains the original frequency stability specification (±50ppm). Selection depends on frequency tolerance requirements for the application.

Q: Why is FNETHE025 packaged in Tape & Reel format?

A: FNETHE025 is supplied in Tape & Reel (TR) packaging, which is standard for high-volume production environments. This packaging format enables automated assembly processes. The electrical specifications remain identical to bulk-packaged alternatives.

Q: Can SXO75C3A271-25.000M from Suntsu Electronics be used as a direct replacement?

A: SXO75C3A271-25.000M meets all critical electrical and mechanical specifications of FN2500169. The maximum supply current is 16mA (vs. 15mA), which is within acceptable tolerance for most applications. Verify power supply capability before substitution.

Q: What is the significance of the reduced height in FNETHE025 and SXO75C3A271-25.000M?

A: FNETHE025 has a seated height of 0.061" (1.55mm) and SXO75C3A271-25.000M has 0.063" (1.60mm), compared to 0.071" (1.80mm) for FN2500169. These reductions are beneficial for applications with height constraints or compact PCB layouts. Verify clearance requirements before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: All listed substitute parts are ROHS3 compliant, matching the compliance status of FN2500169. All parts maintain Moisture Sensitivity Level 1 (Unlimited) except SXO75C3A271-25.000M, for which this specification is not provided.

Q: Which substitute part offers the best frequency stability?

A: Both FN2500171 and FNETHE025 offer ±25ppm frequency stability, which is tighter than the FN2500169 specification of ±50ppm. Selection between these two depends on packaging requirements (Bulk vs. Tape & Reel) and operating temperature range needs.
