Engineering Selection Recommendations

ABLS3-11.0592MHZ-D4Y-T (Abracon LLC) - Primary Substitute

The ABLS3-11.0592MHZ-D4Y-T is the preferred substitute for the obsolete 9C11000002. This part maintains all critical electrical parameters including frequency, frequency stability, operating temperature range, and package specification. The ABLS3 series offers active product status with full availability. REACH Unaffected status provides regulatory advantage over the original part. Load capacitance differs at 18pF versus 22pF, and ESR is 50 Ohms versus 40 Ohms; these variations are within acceptable tolerance for HC-49/US crystal applications. Moisture sensitivity level is not applicable, indicating superior handling characteristics.

ABLS2-11.0592MHZ-D4Y-T (Abracon LLC) - Secondary Substitute

The ABLS2-11.0592MHZ-D4Y-T provides equivalent electrical performance to the ABLS3 variant with identical frequency, stability, and temperature specifications. This part maintains active product status and ROHS3 compliance. The ABLS2 series differs in height specification (0.130" versus 0.098" for ABLS3) and carries REACH Affected status. Load capacitance and ESR parameters match the ABLS3 specification.

LP111F33IDT (CTS-Frequency Controls) - Alternative Substitute

The LP111F33IDT from CTS-Frequency Controls meets all primary electrical and mechanical requirements with 11.0592 MHz frequency and ±30ppm stability. This part carries active product status and ROHS3 compliance with REACH Unaffected status. Load capacitance is specified at 18pF with 60 Ohms ESR. Dimensional variations exist in length (0.437" versus 0.449") and height (0.126" versus 0.161"). Moisture sensitivity level is 1 (Unlimited), matching the original part specification.

LP111F33IET (CTS-Frequency Controls) - Alternative Substitute

The LP111F33IET provides equivalent frequency and stability specifications with active product status and ROHS3 compliance. Load capacitance is specified at 20pF, closer to the original 22pF specification, with 60 Ohms ESR. Dimensional and MSL characteristics match the LP111F33IDT variant. REACH Unaffected status applies.

Frequently Asked Questions (FAQ)

Q: Can the ABLS3-11.0592MHZ-D4Y-T be used as a direct replacement for the 9C11000002?

A: The ABLS3-11.0592MHZ-D4Y-T is electrically compatible as a substitute. Both parts share identical frequency (11.0592 MHz), frequency stability (±30ppm), operating temperature range (-40°C ~ 85°C), package type (HC-49/US), and mounting method (Surface Mount). Load capacitance differs at 18pF versus 22pF, and ESR is 50 Ohms versus 40 Ohms. These parameter variations are within acceptable ranges for HC-49/US crystal oscillator applications and do not prevent substitution.

Q: What is the significance of the load capacitance difference between the 9C11000002 (22pF) and substitute parts (18pF or 20pF)?

A: Load capacitance specifies the capacitive load at which the crystal frequency is calibrated. The 9C11000002 is calibrated at 22pF, while substitute parts are calibrated at 18pF or 20pF. Substitution requires circuit design verification to confirm that the oscillator circuit can accommodate the different load capacitance specification. The frequency tolerance of ±30ppm applies to each part at its specified load capacitance.

Q: How do ESR differences affect substitution compatibility?

A: Equivalent Series Resistance (ESR) affects crystal oscillator startup characteristics and power consumption. The 9C11000002 specifies 40 Ohms ESR, while substitutes range from 50 to 60 Ohms. Higher ESR values may increase startup time and power draw but do not prevent functional substitution in most applications. Circuit design verification is necessary to confirm compatibility with the oscillator circuit's ESR tolerance specifications.

Q: Why is the ABLS3-11.0592MHZ-D4Y-T recommended over the ABLS2-11.0592MHZ-D4Y-T?

A: Both Abracon parts maintain identical electrical specifications. The ABLS3 variant offers lower seated height (0.098" versus 0.130"), providing design flexibility for space-constrained applications. Additionally, the ABLS3 carries REACH Unaffected status, while the ABLS2 is REACH Affected. For new designs and applications without specific height constraints, the ABLS3 is the preferred selection.

Q: What does REACH Unaffected status mean for component selection?

A: REACH Unaffected status indicates the component is not subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulatory requirements. REACH Affected components require additional compliance documentation and supply chain management. For applications with strict regulatory requirements, REACH Unaffected parts (ABLS3, LP111F33IDT, LP111F33IET) are preferred over REACH Affected parts (9C11000002, ABLS2).

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The original 9C11000002 packaging specification is not provided in the available data. Tape & Reel packaging is standard for surface mount HC-49/US crystals and is compatible with standard pick-and-place equipment.

Q: Can LP111F33IET (20pF load capacitance) be used instead of LP111F33IDT (18pF load capacitance)?

A: Both CTS-Frequency Controls parts maintain identical frequency, stability, temperature range, and package specifications. The load capacitance difference (20pF versus 18pF) requires circuit design verification. The LP111F33IET with 20pF load capacitance is closer to the original 9C11000002 specification of 22pF and may require less circuit modification if substituting the original part.

Q: What is the significance of Moisture Sensitivity Level (MSL) classification?

A: Moisture Sensitivity Level indicates the component's susceptibility to moisture absorption during storage and handling. MSL 1 (Unlimited) means the component has no moisture sensitivity restrictions and can be stored indefinitely without special precautions. Abracon ABLS2 and ABLS3 parts specify MSL as Not Applicable, indicating superior moisture resistance. CTS-Frequency Controls LP111F33IDT and LP111F33IET maintain MSL 1 (Unlimited), matching the original part specification.
