ECS-.327-6-13 Equivalent & Substitute Parts

Part Overview

The ECS-.327-6-13 is a 32.768 kHz tuning fork crystal with 6pF load capacitance, designed for through-hole mounting in cylindrical can packages. This component is commonly used in real-time clock (RTC) applications, timekeeping circuits, and low-frequency oscillator designs. The part is currently active in production with 713 units in stock. Substitute parts are necessary when the primary part becomes unavailable, when alternative compliance certifications are required, or when design revisions call for different ESR characteristics within the same functional specification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-.327-6-13 is determined by strict adherence to the following parameters:

Critical Parameters (Must Match Exactly):

• Frequency: 32.768 kHz
• Frequency Tolerance: ±20ppm
• Load Capacitance: 6pF
• Operating Mode: Fundamental
• Mounting Type: Through Hole
• Package Type: Cylindrical Can, Radial
• Operating Temperature Range: -10°C ~ 60°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• ESR (Equivalent Series Resistance): Variation permitted within design margin
• Physical dimensions: Minor variations acceptable within package classification
• RoHS compliance status: May differ between main part and substitutes
• Manufacturer and series designation: Different manufacturers acceptable

All listed substitute parts meet the critical parameter requirements and are therefore functionally equivalent for circuit applications requiring the ECS-.327-6-13 specification.

Parameter Comparison

Engineering Selection Recommendations

ECS-.327-6-13X (ECS Inc.): This part is the direct parametric equivalent with identical ESR (35 kOhms) and all critical electrical specifications. The primary distinction is ROHS3 compliance certification. This substitute is recommended when RoHS3 compliance is a design requirement or when higher inventory availability (47,696 units) is advantageous for production planning.

G23270006 (Diodes Incorporated): This substitute maintains all critical parameters with a 5 kOhm ESR increase (40 kOhms vs. 35 kOhms). Physical dimensions show minor variation (0.079" diameter vs. 0.083"). ROHS3 compliance is certified. This part is suitable for applications where ESR tolerance permits the higher value and where Diodes Incorporated supply chain integration is preferred.

VT200F-6PF20PPM (Seiko Instruments): This substitute maintains all critical parameters with a 15 kOhm ESR increase (50 kOhms vs. 35 kOhms). Physical dimensions show minor variation (0.074" diameter vs. 0.083"). ROHS3 compliance is certified. This part is suitable for applications where ESR tolerance permits the higher value and where Seiko Instruments supply chain integration is preferred. Highest inventory availability (74,254 units) supports extended production runs.

All substitutes are active products with established supply chains and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ECS-.327-6-13X be used as a direct replacement for ECS-.327-6-13?

A: Yes. ECS-.327-6-13X is a parametric equivalent with identical frequency, tolerance, load capacitance, ESR, and operating temperature range. The primary difference is ROHS3 compliance certification on the substitute part.

Q: What is the significance of ESR differences between the main part and substitutes?

A: ESR (Equivalent Series Resistance) affects circuit startup time and oscillation amplitude. The main part specifies 35 kOhms, while G23270006 specifies 40 kOhms and VT200F-6PF20PPM specifies 50 kOhms. Substitution is valid when circuit design margins accommodate these ESR variations. Consult oscillator circuit design specifications to confirm ESR tolerance.

Q: Are physical dimension variations between substitutes significant?

A: Minor dimension variations exist within the cylindrical can, radial package classification. All parts maintain the same mounting footprint and through-hole compatibility. Verify PCB layout accommodates the maximum seated height of 0.244" (6.20mm) for all parts.

Q: Which substitute offers the best supply availability?

A: VT200F-6PF20PPM (Seiko Instruments) offers the highest inventory at 74,254 units, followed by ECS-.327-6-13X at 47,696 units. For high-volume production, either part supports extended lead times.

Q: Are all substitutes RoHS3 compliant?

A: ECS-.327-6-13X, G23270006, and VT200F-6PF20PPM are all ROHS3 compliant. The original ECS-.327-6-13 is RoHS non-compliant. Select a compliant substitute when design requirements mandate RoHS3 certification.

Q: Can substitutes be mixed within the same production batch?

A: All substitutes meet identical critical electrical parameters (frequency, tolerance, load capacitance, operating temperature, and operating mode). Mixing is permissible from a functional standpoint. However, verify that ESR variations do not impact oscillator circuit performance when multiple suppliers are used in the same design revision.
