ECS-100AX-184 Equivalent & Substitute Parts

Part Overview

The ECS-100AX-184 is an 18.432 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 RoHS3 compliant. Substitute parts are identified when parametric equivalence is maintained across critical electrical and mechanical specifications, enabling direct replacement in circuit applications where the original part number becomes unavailable or inventory constraints require alternative sourcing.

Substitute Part Grouping Explanation

Substitution eligibility for the ECS-100AX-184 is determined by strict parametric matching across the following critical specifications:

• Frequency: 18.432 MHz (exact match required)
• Output Configuration: TTL (exact match required)
• Supply Voltage: 5V (exact match required)
• Frequency Stability: ±100ppm (exact match required)
• Operating Temperature Range: 0°C ~ 70°C (exact match required)
• Maximum Supply Current: 30mA (exact match required)
• Package/Case: 14-DIP, 4 Leads (Full Size, Metal Can) (exact match required)
• Mounting Type: Through Hole (exact match required)
• Physical Dimensions: 0.821" L x 0.520" W; 0.200" max height (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The ECS-100A-184 meets all parametric equivalence criteria and qualifies as a direct substitute for the ECS-100AX-184.

Parameter Comparison

Engineering Selection Recommendations

Both the ECS-100AX-184 and ECS-100A-184 are Active product status components manufactured by ECS Inc. with identical parametric specifications across all electrical and mechanical characteristics. The primary distinction is regulatory compliance: the ECS-100AX-184 carries RoHS3 compliance certification, while the ECS-100A-184 is RoHS non-compliant.

Selection between these parts depends on application regulatory requirements. Applications subject to RoHS3 mandates must use the ECS-100AX-184. Applications without RoHS3 requirements may use either part based on availability and inventory considerations. Both parts are functionally interchangeable in circuit design and PCB layout.

Frequently Asked Questions (FAQ)

Q: Can the ECS-100A-184 be used as a direct replacement for the ECS-100AX-184?

A: Yes, from a parametric and functional standpoint. Both parts share identical electrical specifications (18.432 MHz, TTL output, 5V supply, ±100ppm stability, 30mA max current) and mechanical characteristics (14-DIP through-hole package, identical dimensions and height). The distinction is regulatory compliance: ECS-100AX-184 is RoHS3 compliant while ECS-100A-184 is not. Selection depends on application compliance requirements.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the identical 14-DIP, 4 Leads (Full Size, Metal Can) package with through-hole mounting. Physical dimensions (0.821" L x 0.520" W, 0.200" max height) and pin configuration are identical, enabling direct PCB substitution without layout modifications.

Q: What is the significance of the RoHS compliance difference?

A: RoHS3 compliance indicates the part meets current European Union Restriction of Hazardous Substances regulations. Applications destined for EU markets or subject to RoHS3 mandates require the ECS-100AX-184. The ECS-100A-184, being RoHS non-compliant, is suitable only for applications without RoHS3 regulatory requirements.

Q: Are both parts currently available for procurement?

A: Both parts are listed as Active product status. Inventory availability varies: ECS-100AX-184 has 692 pcs in stock, while ECS-100A-184 has 2167 pcs in stock. Availability should be confirmed with the supplier for current procurement timelines.

Q: Do these parts have identical frequency stability and operating temperature ranges?

A: Yes. Both parts operate across 0°C to 70°C and maintain ±100ppm frequency stability. Operating conditions and performance characteristics are identical.
