Substitute Part Grouping Explanation

Substitute parts for the FK5000013 are identified based on strict parameter matching across electrical and mechanical specifications. The primary substitution criteria are:

Critical Parameters for Substitution:

• Frequency: 50 MHz (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Function: Enable/Disable (exact match required)

Allowable Parameter Variations:

• Output Type: LVCMOS or CMOS (both compatible with 3.3V logic systems)
• Frequency Stability: ±50ppm or tighter (±25ppm acceptable)
• Operating Temperature Range: -40°C ~ 85°C or subset thereof
• Maximum Supply Current: 10mA or higher (backward compatible)
• Maximum Seated Height: 0.045" (1.15mm) or 0.051" (1.30mm) (within PCB assembly tolerances)

Two substitute parts meet these criteria: FK5000022 (Diodes Incorporated, MFR Recommended) and XK372-050.0M (Connor Winfield, Direct Manufacturer).

Parameter Comparison

Engineering Selection Recommendations

FK5000022 (Diodes Incorporated - MFR Recommended Substitute): This part is designated as the manufacturer-recommended substitute. It maintains identical physical dimensions, package type, and supply voltage. The output type differs (CMOS vs. LVCMOS), which is compatible with 3.3V logic systems. Frequency stability is improved at ±25ppm compared to ±50ppm. The operating temperature range is narrower (-20°C ~ 70°C vs. -40°C ~ 85°C), and maximum supply current is higher at 18mA. Selection of FK5000022 is appropriate when the narrower temperature range and higher current consumption are acceptable for the application, and when improved frequency stability is beneficial.

XK372-050.0M (Connor Winfield - Direct Manufacturer Substitute): This part provides direct parameter equivalence to FK5000013, with identical LVCMOS output, frequency stability (±50ppm), operating temperature range (-40°C ~ 85°C), and maximum supply current (10mA). The maximum seated height is 0.051" (1.30mm) compared to 0.045" (1.15mm), which remains within standard PCB assembly tolerances. Selection of XK372-050.0M is appropriate when exact electrical parameter matching and extended temperature range operation are required, or when sourcing from Connor Winfield is preferred.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and Active product status, ensuring long-term availability and regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can FK5000022 be used as a direct replacement for FK5000013? A: FK5000022 is electrically compatible as a substitute. Both parts operate at 50 MHz with 3.3V supply and Enable/Disable function in identical 4-SMD, No Lead packaging. The primary differences are output type (CMOS vs. LVCMOS), frequency stability (±25ppm vs. ±50ppm), and operating temperature range (-20°C ~ 70°C vs. -40°C ~ 85°C). Substitution is valid when the application does not require the extended temperature range or when improved frequency stability is acceptable.

Q: What is the difference between LVCMOS and CMOS output types? A: Both LVCMOS and CMOS are compatible logic output standards for 3.3V systems. LVCMOS (Low Voltage CMOS) is optimized for lower voltage operation and typically offers lower power consumption. CMOS is a broader classification. For 3.3V supply applications, both output types are functionally compatible with standard logic inputs.

Q: Can XK372-050.0M be used in place of FK5000013? A: Yes. XK372-050.0M provides direct electrical and mechanical equivalence to FK5000013. Both parts feature 50 MHz frequency, LVCMOS output, 3.3V supply, ±50ppm frequency stability, and -40°C ~ 85°C operating temperature range. The maximum seated height differs by 0.006" (0.15mm), which is within standard PCB assembly tolerances and does not affect functionality or compatibility.

Q: Are all three parts pin-compatible? A: Yes. All three parts use identical 4-SMD, No Lead packaging with matching physical dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm). Pin configuration and function assignments are identical across all three parts.

Q: Which substitute part should be selected for extended temperature range applications? A: XK372-050.0M maintains the full operating temperature range of -40°C ~ 85°C, matching FK5000013. FK5000022 has a narrower range of -20°C ~ 70°C. For applications requiring extended temperature operation, XK372-050.0M is the appropriate selection.

Q: Do all parts meet RoHS and REACH compliance requirements? A: Yes. FK5000013, FK5000022, and XK372-050.0M are all ROHS3 Compliant and REACH Unaffected, ensuring regulatory compliance for commercial and industrial applications.

Q: What is the significance of Moisture Sensitivity Level 1 (Unlimited)? A: MSL 1 (Unlimited) indicates the component has no moisture sensitivity restrictions. These parts do not require special moisture-controlled storage or handling procedures and can be stored under standard industrial conditions without degradation.
