Diodes Incorporated G93270003 32.768 kHz Crystal Equivalent & Substitute Parts

Part Overview

The Diodes Incorporated G93270003 is a 32.768 kHz tuning fork crystal with 12.5pF load capacitance and 90 kOhms equivalent series resistance (ESR). This component is classified as obsolete, making substitute parts necessary for new designs and ongoing production requirements. The part operates across the -40°C to 85°C temperature range and meets RoHS3 compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the G93270003 is determined by the following critical electrical and mechanical parameters:

• Frequency: 32.768 kHz (exact match required)
• Frequency Tolerance: ±10ppm (exact match required)
• Load Capacitance: 12.5pF (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• ESR: Acceptable range 70–90 kOhms (minor variation permitted)
• Packaging: Surface mount or through-hole configurations acceptable
• RoHS Compliance: ROHS3 or equivalent required

The substitute part G9327A014 meets all critical electrical parameters with a lower ESR value (70 kOhms versus 90 kOhms), which is acceptable for this application. The primary difference is the packaging format: G9327A014 uses surface mount technology (2-SMD, No Lead) in a 2.00mm × 1.20mm footprint, whereas the original G93270003 uses a different package configuration.

Parameter Comparison

Engineering Selection Recommendations

The G9327A014 is the primary substitute for the obsolete G93270003. Selection is based on the following factors:

• Product Status: G9327A014 is active and available in production quantities (938 pcs in stock), whereas G93270003 is obsolete.
• Electrical Compatibility: Both parts share identical frequency (32.768 kHz), frequency tolerance (±10ppm), load capacitance (12.5pF), and operating temperature range (-40°C to 85°C). The ESR difference (70 kOhms vs. 90 kOhms) is within acceptable tolerance for 32.768 kHz crystal applications.
• Compliance: G9327A014 meets ROHS3 compliance, satisfying modern regulatory requirements.
• Packaging Consideration: G9327A014 uses surface mount technology (2-SMD, No Lead, 2.00mm × 1.20mm). PCB layout and assembly process compatibility must be verified before implementation.

Frequently Asked Questions (FAQ)

Q: Can G9327A014 directly replace G93270003 in existing designs?

A: Electrical substitution is valid based on matching frequency, tolerance, load capacitance, and operating temperature. However, physical package differences must be evaluated. G9327A014 is a surface mount component (2-SMD, No Lead), whereas the original part's package format is not specified. PCB footprint compatibility must be confirmed.

Q: What is the significance of the ESR difference (90 kOhms vs. 70 kOhms)?

A: The ESR (Equivalent Series Resistance) difference of 20 kOhms is acceptable for 32.768 kHz tuning fork crystals. Lower ESR (70 kOhms) in G9327A014 may result in slightly lower power consumption and improved oscillator startup characteristics. This is not a limiting factor for substitution.

Q: Why is G93270003 obsolete?

A: Product obsolescence is determined by the manufacturer. G9327A014 represents the active replacement in the Diodes Incorporated product line and is recommended for all new designs.

Q: Are there packaging options for G9327A014?

A: G9327A014 is supplied in Tape & Reel (TR) format for automated assembly. This is the standard packaging for surface mount crystals in production environments.

Q: What compliance certifications apply to both parts?

A: Both G93270003 and G9327A014 are RoHS compliant and REACH unaffected. G9327A014 specifically meets ROHS3 standards. Both carry ECCN classification EAR99 and HTSUS code 8541.60.0010.
