Key Parameters

Substitute Part Grouping Explanation

Substitution of the ECS-100-S-5P-TR is determined by strict equivalence across the following critical parameters:

• Frequency: 10 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• ESR: 50 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Package / Case: HC-49/US (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Operating Temperature Range: -10°C ~ 70°C (exact match required)
• Load Capacitance: Series (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

The ECS-100-S-5PX-TR meets all these criteria and qualifies as a parametric equivalent substitute.

Parameter Comparison

Engineering Selection Recommendations

The ECS-100-S-5PX-TR is the direct parametric equivalent for the ECS-100-S-5P-TR. Both parts share identical electrical and mechanical specifications across all critical parameters. The primary distinction is product lifecycle status: the ECS-100-S-5P-TR is designated "Not For New Designs," while the ECS-100-S-5PX-TR carries "Active" status, indicating ongoing manufacturer support and availability.

The ECS-100-S-5PX-TR also provides improved compliance posture, meeting ROHS3 requirements compared to the non-compliant status of the original part. Both parts maintain REACH Unaffected and EAR99 ECCN classifications.

For applications requiring the 10 MHz HC-49/US crystal with 50 Ohms ESR and ±30ppm tolerance, the ECS-100-S-5PX-TR is the appropriate selection for new designs and ongoing production.

Frequently Asked Questions (FAQ)

Q: Can the ECS-100-S-5PX-TR be used as a direct replacement for the ECS-100-S-5P-TR?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 10 MHz frequency, ±30ppm tolerance, ±50ppm stability, 50 Ohms ESR, HC-49/US package, and -10°C to 70°C operating range. No circuit modifications are required.

Q: What is the difference between the CSM-7 and CSM-7X series designations?

A: The series designation reflects the product generation. The CSM-7X (ECS-100-S-5PX-TR) represents the current active product line, while CSM-7 (ECS-100-S-5P-TR) is the legacy designation. The electrical and mechanical specifications remain equivalent.

Q: Does the RoHS compliance difference affect compatibility?

A: The ECS-100-S-5PX-TR meets ROHS3 compliance, while the ECS-100-S-5P-TR does not. For applications subject to RoHS regulations or customer requirements mandating RoHS compliance, the ECS-100-S-5PX-TR is the appropriate choice. Both parts are functionally equivalent in circuit operation.

Q: Are there inventory or lead time considerations between these parts?

A: The ECS-100-S-5PX-TR is the active product with higher reported inventory levels. The ECS-100-S-5P-TR is classified "Not For New Designs," which may affect long-term availability. For new production, the ECS-100-S-5PX-TR is recommended.

Q: Can these crystals be used interchangeably in existing PCB designs?

A: Yes. Both parts use identical HC-49/US surface mount packages with matching footprints, dimensions (0.449" L x 0.189" W, 11.40mm x 4.80mm), and maximum seated height (0.169", 4.30mm). No PCB layout modifications are necessary.
