GC2500100 Equivalent & Substitute Parts

Part Overview

The GC2500100 is a 25 MHz fundamental mode crystal oscillator manufactured by Diodes Incorporated, part of the SaRonix-eCera™ GC series. This surface mount device operates across the temperature range of -10°C to 60°C and is designed for applications requiring precise frequency generation at 25 MHz with tight frequency tolerance specifications.

The GC2500100 is currently in active production status. Substitute parts may be required due to inventory constraints, regional availability, or specific application requirements where alternative electrical or mechanical parameters are acceptable within system design tolerances.

Substitute Part Grouping Explanation

Substitution of the GC2500100 is permissible with the ABLS-25.000MHZ-20-A4-F-T based on the following criteria:

Core Matching Parameters:

• Identical frequency: 25 MHz
• Identical frequency tolerance: ±30ppm
• Identical frequency stability: ±50ppm
• Identical operating mode: Fundamental
• Identical operating temperature range: -10°C to 60°C
• Identical package type: HC-49/US
• Identical mounting type: Surface Mount

Allowable Parameter Variations:

• Load capacitance: 16pF (main part) vs. 20pF (substitute) — variation within typical crystal design margins
• ESR: 30 Ohms (main part) vs. 40 Ohms (substitute) — within acceptable operating range for most applications
• Physical dimensions: Minor variations in length and width (11.70mm × 4.80mm vs. 11.40mm × 4.70mm) — compatible with HC-49/US package envelope

Parameter Comparison

Engineering Selection Recommendations

Both the GC2500100 and ABLS-25.000MHZ-20-A4-F-T are active production components with full RoHS3 compliance, making them suitable for modern electronic applications subject to environmental regulations.

The GC2500100 features a lower ESR specification (30 Ohms) and lower load capacitance requirement (16pF), which may provide advantages in circuits with tighter impedance matching requirements or lower power consumption targets.

The ABLS-25.000MHZ-20-A4-F-T offers higher inventory availability (2700 units in stock vs. 1094 units) and represents an equivalent functional alternative where the 4 Ohm ESR increase and 4pF load capacitance increase fall within acceptable design margins for standard 25 MHz crystal applications.

Selection between these parts should be based on circuit design requirements, inventory availability, and lead time considerations. Both components maintain identical frequency accuracy and temperature stability specifications.

Frequently Asked Questions (FAQ)

Q: Can the ABLS-25.000MHZ-20-A4-F-T directly replace the GC2500100 in my circuit?

A: Direct substitution is permissible if your circuit design accommodates the specified parameter variations: 20pF load capacitance (vs. 16pF) and 40 Ohms ESR (vs. 30 Ohms). Both components share identical frequency, tolerance, stability, temperature range, and HC-49/US package specifications. Circuit simulation or bench testing is appropriate to confirm performance in your specific application.

Q: What is the significance of the load capacitance difference?

A: Load capacitance affects the crystal's operating frequency in the context of the circuit's total capacitive load. The 4pF difference between these parts may require minor adjustments to external load capacitors in the oscillator circuit. This variation is within typical design tolerances for 25 MHz crystal applications.

Q: Are there any compliance or regulatory differences between these parts?

A: Both components are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8541.60.0060) classifications. The GC2500100 carries MSL 1 (Unlimited) rating, while the ABLS part lists MSL as Not Applicable. Both are suitable for standard commercial and industrial applications.

Q: Do these crystals require different PCB footprints?

A: Both components use the HC-49/US package with identical mounting type (Surface Mount). Physical dimensions are within 0.21mm length and 0.10mm width tolerances, making them compatible with standard HC-49/US PCB footprints without layout modifications.

Q: What is the difference between frequency tolerance and frequency stability?

A: Frequency tolerance (±30ppm) specifies the accuracy of the crystal's nominal frequency at room temperature during manufacturing. Frequency stability (±50ppm) defines the maximum frequency variation across the operating temperature range (-10°C to 60°C). Both parameters are identical for these parts.
