Substitute Part Grouping Explanation

Substitution of the ECS-61-32-7S-TR is determined by strict equivalence across the following critical parameters:

• Frequency: 6.144 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 32pF (exact match required)
• ESR: 100 Ohms (exact match required)
• Package / Case: 4-SOJ, 9.40mm pitch (exact match required)
• Physical Dimensions: 0.492" L x 0.181" W, 0.146" max height (exact match required)
• Operating Temperature Range: -10°C ~ 70°C (exact match required)
• Mounting Type: Surface Mount (exact match required)

The substitute part ECS-61-32-7SX-TR meets all these criteria and is therefore a direct parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

The ECS-61-32-7SX-TR is a direct parametric equivalent to the ECS-61-32-7S-TR across all electrical and mechanical specifications. The primary distinction is RoHS compliance status: the ECS-61-32-7S-TR is RoHS non-compliant, while the ECS-61-32-7SX-TR is ROHS3 compliant. Both parts are classified as "Not For New Designs."

For applications requiring RoHS3 compliance or regulatory adherence to current environmental standards, the ECS-61-32-7SX-TR is the appropriate selection. For legacy systems where RoHS compliance is not a requirement, either part is functionally equivalent. Both parts share identical electrical performance, frequency characteristics, and physical form factor, ensuring direct interchangeability in circuit design and PCB layout.
