ECS-100A-640 Equivalent & Substitute Parts

Part Overview

The ECS-100A-640 is a 64 MHz XO (Standard) TTL Oscillator operating at 5V in a 14-DIP through-hole package with a full-size metal can form factor. This component is classified as Active product status and is designed for applications requiring stable frequency generation at TTL output levels. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same frequency, output type, voltage supply, and package configuration.

Substitute Part Grouping Explanation

Substitution of the ECS-100A-640 is determined by strict equivalence across the following critical parameters:

• Frequency: 64 MHz (exact match required)
• Output Type: TTL (exact match required)
• Voltage Supply: 5V (exact match required)
• Frequency Stability: ±100ppm (exact match required)
• Operating Temperature Range: 0°C ~ 70°C (exact match required)
• Current Supply (Max): 70mA (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: 14-DIP, 4 Leads (Full Size, Metal Can) (exact match required)
• Physical Dimensions: 0.821" L x 0.520" W, Height 0.200" max (exact match required)

The ECS-100AX-640 meets all these criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ECS-100A-640 and ECS-100AX-640 are Active product status components with identical electrical and mechanical specifications. The primary distinction is RoHS compliance status: the ECS-100A-640 is RoHS non-compliant, while the ECS-100AX-640 is ROHS3 compliant. Selection between these parts should be based on regulatory and environmental requirements applicable to the end application. The ECS-100AX-640 provides compliance advantage for applications subject to RoHS3 regulations. Both parts maintain equivalent REACH and ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can the ECS-100AX-640 directly replace the ECS-100A-640 in existing designs?

A: Yes. The ECS-100AX-640 is a parametric equivalent with identical electrical performance, frequency output, voltage supply, current consumption, operating temperature range, and physical package dimensions. Direct substitution is supported from an electrical and mechanical standpoint.

Q: What is the difference between these two part numbers?

A: The primary difference is RoHS compliance status. The ECS-100AX-640 is ROHS3 compliant, while the ECS-100A-640 is RoHS non-compliant. All other specifications, including frequency, output type, voltage, stability, and package form factor, are identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts use the 14-DIP, 4 Leads (Full Size, Metal Can) package with dimensions of 0.821" L x 0.520" W (20.86mm x 13.20mm) and a maximum seated height of 0.200" (5.08mm). PCB layout and mounting considerations are identical.

Q: Which part should be selected for new designs?

A: Selection depends on regulatory requirements. For applications requiring RoHS3 compliance, the ECS-100AX-640 is the appropriate choice. Both parts are Active status and available in production quantities.

Q: Are there any performance differences in frequency stability or current consumption?

A: No. Both parts maintain ±100ppm frequency stability and 70mA maximum supply current. Operating temperature range is identical at 0°C ~ 70°C. Performance characteristics are equivalent.
