GC0800002 Equivalent & Substitute Parts

Part Overview

The GC0800002 is an 8 MHz fundamental mode crystal oscillator manufactured by Diodes Incorporated, packaged in HC-49/US surface mount configuration. This component is designed for timing and frequency control applications requiring 18pF load capacitance. The part is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified operating parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the GC0800002 is determined by strict equivalence across the following critical parameters:

• Frequency: 8 MHz (exact match required)
• Frequency Tolerance: ±20 ppm (exact match required)
• Load Capacitance: 18 pF (exact match required)
• Operating Mode: Fundamental (exact match required)
• Package / Case: HC-49/US (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -40°C to 85°C (minimum required)
• RoHS Status: ROHS3 Compliant (compliance required)

The ECS-80-18-5G3X-JGN-TR meets all substitution criteria. Variations in ESR (Equivalent Series Resistance) and physical dimensions within tolerance do not affect functional substitutability when all primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

Both GC0800002 and ECS-80-18-5G3X-JGN-TR are active production components with ROHS3 compliance and identical MSL ratings. Selection between these parts is based on availability and supply chain requirements rather than functional differences. The ECS-80-18-5G3X-JGN-TR exhibits lower ESR (70 Ohms versus 100 Ohms), which may provide marginal advantages in power consumption and startup characteristics, though both values remain within acceptable ranges for standard 8 MHz timing applications. Both components maintain identical frequency tolerance, load capacitance, and operating temperature specifications.

Frequently Asked Questions (FAQ)

Q: Can ECS-80-18-5G3X-JGN-TR replace GC0800002 in existing designs?

A: Yes. Both parts meet identical electrical specifications for frequency, tolerance, load capacitance, and operating temperature. HC-49/US package compatibility and surface mount configuration are identical. No circuit redesign is required.

Q: What is the significance of the ESR difference (100 Ohms vs. 70 Ohms)?

A: ESR affects startup time and power consumption characteristics. The lower ESR of the ECS part may reduce startup transients, but both values are within normal operating ranges for 8 MHz fundamental mode crystals. Circuit performance remains equivalent.

Q: Are there any compliance or certification differences?

A: No. Both parts carry ROHS3 compliance, identical MSL ratings, and equivalent REACH and ECCN classifications.

Q: What are the physical dimension differences?

A: Length differs by 0.012" (0.30mm) and width by 0.004" (0.10mm). Height is identical at 0.165" (4.20mm). These variations remain within HC-49/US package tolerances and do not affect PCB layout or mechanical fit.

Q: Which part should be selected for new designs?

A: Selection should be based on current supply availability and lead time. Both parts are functionally equivalent for 8 MHz timing applications with 18pF load capacitance requirements.
