ECS-60-32-4XDN Equivalent & Substitute Parts

Part Overview

The ECS-60-32-4XDN is a 6 MHz through-hole crystal oscillator in HC-49/US package, designed for fundamental mode operation with 32pF load capacitance and 100 Ohms ESR. This Active product is ROHS3 compliant and suitable for new designs. Equivalent and substitute parts may be required due to inventory availability, design phase transitions, or specific compliance requirements across different production batches or design revisions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-60-32-4XDN is determined by the following critical parameters:

• Frequency: 6 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 32pF (exact match required)
• Package / Case: HC-49/US (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Mode: Fundamental (exact match required)

Variations in ESR, Frequency Stability, Operating Temperature Range, Product Status, and RoHS compliance are permitted within the substitute group, provided all critical parameters remain identical. The following parts meet these substitution criteria:

• ECS-60-32-4X
• ECS-60-32-4DN

Parameter Comparison

Engineering Selection Recommendations

For new designs, ECS-60-32-4XDN or ECS-60-32-4X are the appropriate selections, both carrying Active product status and ROHS3 compliance. ECS-60-32-4XDN provides the widest operating temperature range (-40°C ~ 85°C) and is recommended for applications requiring extended temperature performance.

ECS-60-32-4X is suitable for applications with operating temperature requirements limited to -10°C ~ 70°C and offers improved frequency stability (±50ppm versus ±100ppm). Both parts are electrically and mechanically interchangeable with identical frequency, tolerance, load capacitance, and package specifications.

ECS-60-32-4DN is designated Not For New Designs and does not meet ROHS3 compliance. This part is suitable only for legacy system maintenance or replacement applications where RoHS compliance is not a requirement and existing designs have validated this component.

Frequently Asked Questions (FAQ)

Q: Can ECS-60-32-4X be used as a direct replacement for ECS-60-32-4XDN?

A: Yes. Both parts share identical frequency (6 MHz), frequency tolerance (±30ppm), load capacitance (32pF), ESR (100 Ohms), and HC-49/US package specifications. The primary difference is operating temperature range: ECS-60-32-4XDN operates -40°C ~ 85°C while ECS-60-32-4X operates -10°C ~ 70°C. Substitution is valid only if your application temperature requirements fall within -10°C ~ 70°C.

Q: Is ECS-60-32-4DN compatible with ECS-60-32-4XDN?

A: Electrical and mechanical compatibility exists. Both parts operate at 6 MHz with ±30ppm tolerance, 32pF load capacitance, and HC-49/US package. However, ECS-60-32-4DN has 80 Ohms ESR (versus 100 Ohms), is Not For New Designs, and is RoHS non-compliant. Use only in legacy applications where RoHS compliance is not mandated.

Q: What are the critical parameters that must match for substitution?

A: Frequency (6 MHz), frequency tolerance (±30ppm), load capacitance (32pF), package type (HC-49/US), mounting type (through hole), and operating mode (fundamental) must remain identical. Variations in ESR, frequency stability, temperature range, and compliance status are permissible.

Q: Does operating temperature range affect substitution eligibility?

A: Operating temperature range does not prevent substitution but must be evaluated against application requirements. ECS-60-32-4XDN and ECS-60-32-4DN both support -40°C ~ 85°C, while ECS-60-32-4X supports only -10°C ~ 70°C. Select based on your circuit's actual operating environment.

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

A: Frequency tolerance (±30ppm for all three parts) specifies the initial accuracy at room temperature. Frequency stability (±100ppm for ECS-60-32-4XDN and ECS-60-32-4DN; ±50ppm for ECS-60-32-4X) specifies the maximum frequency variation over the operating temperature range. ECS-60-32-4X provides tighter stability performance.
