• ESR: 3 kOhms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: 0°C ~ 60°C (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: HC-49/U (exact match required)
• Physical Dimensions: 0.447" L x 0.183" W, Height 0.530" max (exact match required)

The ECS-10-13-1XH meets all substitution criteria as a parametric equivalent with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The ECS-10-13-1XH is a direct parametric equivalent to the ECS-10-13-1H across all electrical and mechanical specifications. The primary distinction is product lifecycle status: the ECS-10-13-1H is classified as Not For New Designs, while the ECS-10-13-1XH maintains Active status. Additionally, the ECS-10-13-1XH achieves ROHS3 compliance, whereas the ECS-10-13-1H is RoHS non-compliant. Both parts share identical moisture sensitivity classification and regulatory designations (REACH Unaffected, ECCN EAR99, HTSUS 8541.60.0020).

For applications requiring continued support of legacy ECS-10-13-1H designs, the ECS-10-13-1XH provides full functional and mechanical compatibility with improved compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the ECS-10-13-1XH replace the ECS-10-13-1H in existing designs?

A: Yes. The ECS-10-13-1XH is a parametric equivalent with identical frequency (1 MHz), frequency stability (±100ppm), load capacitance (13pF), ESR (3 kOhms), operating temperature range (0°C ~ 60°C), and HC-49/U package dimensions. Direct substitution is supported at the circuit level.

Q: What is the difference between the ECS-10-13-1H and ECS-10-13-1XH?

A: The parts are electrically and mechanically identical. The ECS-10-13-1XH is the active production variant with ROHS3 compliance, while the ECS-10-13-1H is designated Not For New Designs and is RoHS non-compliant.

Q: Are there any physical compatibility concerns when substituting these parts?

A: No. Both parts use the HC-49/U package with identical dimensions: 0.447" L x 0.183" W (11.35mm x 4.65mm) and maximum seated height of 0.530" (13.46mm). Through-hole mounting is identical.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both the ECS-10-13-1H and ECS-10-13-1XH are classified as MSL 1 (Unlimited), indicating no moisture sensitivity constraints.

Q: Are regulatory certifications equivalent between these parts?

A: Both parts share identical REACH status (REACH Unaffected), ECCN classification (EAR99), and HTSUS code (8541.60.0020). The ECS-10-13-1XH provides additional ROHS3 compliance.
