Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECS-8FM-240-TR is determined by strict equivalence across the following critical parameters:

• Frequency: 24 MHz (exact match required)
• Output Type: CMOS, TTL (dual output compatibility)
• Supply Voltage: 5V
• Function: Enable/Disable capability
• Frequency Stability: ±200ppm
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 4-SOJ, 5.08mm pitch
• Mounting Type: Surface Mount
• Current - Supply (Max): 23mA

The ECS-8FMX-240-TR meets all these criteria and qualifies as a parametric equivalent. Differences in product status, packaging format, and compliance certifications do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ECS-8FMX-240-TR is the direct parametric equivalent for the obsolete ECS-8FM-240-TR. All electrical and mechanical specifications are identical, ensuring pin-for-pin and form-factor compatibility in existing circuit designs.

The ECS-8FMX-240-TR offers additional advantages for new procurement:

• Active product status ensures long-term availability and supply chain continuity
• ROHS3 compliance satisfies current environmental and regulatory requirements
• Tape & Reel packaging supports automated assembly processes

For applications requiring RoHS non-compliant components or specific packaging formats, the ECS-8FM-240-TR remains available in current inventory. However, for new designs and ongoing production, the ECS-8FMX-240-TR is the recommended selection.

Frequently Asked Questions (FAQ)

Q: Can the ECS-8FMX-240-TR be used as a direct replacement for the ECS-8FM-240-TR?

A: Yes. The ECS-8FMX-240-TR is a parametric equivalent with identical electrical and mechanical specifications. No circuit modifications are required for substitution.

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

A: The primary differences are product status (Obsolete vs. Active), RoHS compliance (non-compliant vs. ROHS3 Compliant), and packaging format (Cut Tape & Digi-Reel® vs. Tape & Reel). All functional parameters are identical.

Q: Are the packages physically compatible?

A: Yes. Both parts use the 4-SOJ package with 5.08mm pitch and identical dimensions (0.551" L x 0.341" W, 14.00mm x 8.65mm) and height (0.185" / 4.70mm). They are footprint-compatible on PCBs designed for either part.

Q: Does the packaging format affect electrical performance?

A: No. Packaging format (Cut Tape vs. Tape & Reel) is a procurement and assembly consideration only. Electrical and thermal performance remain unchanged.

Q: Which part should be specified for new designs?

A: The ECS-8FMX-240-TR should be specified for new designs due to its Active status and ROHS3 compliance, ensuring regulatory alignment and supply chain stability.
