Engineering Selection Recommendations

ABLS2-6.000MHZ-B4Y-T (Primary Substitute)

The ABLS2-6.000MHZ-B4Y-T is the direct functional equivalent for surface mount applications. This part maintains identical electrical specifications (6 MHz, ±30ppm stability, 18pF load capacitance, fundamental mode operation) and operates within the same temperature range (-20°C to 70°C). The part is manufactured by Abracon LLC with active product status, ensuring long-term availability and supply chain continuity. Physical dimensions align with HC-49/US package specifications. ESR of 100 Ohms falls within acceptable tolerance relative to the original 80 Ohms specification. ROHS3 compliance and EAR99 classification match the original part. This substitute is suitable for direct replacement in surface mount PCB designs without circuit modification.

ABL-6.000MHZ-B4Y-T (Alternative for Through Hole Applications)

The ABL-6.000MHZ-B4Y-T provides electrical equivalence with identical frequency, stability, load capacitance, and operating temperature specifications. This part differs in mounting type (through hole versus surface mount) and is suitable only for designs utilizing through hole PCB footprints. The part maintains ROHS3 compliance and EAR99 classification. ESR specification of 100 Ohms is within acceptable range. REACH status is unaffected, providing potential regulatory advantage in certain supply chain contexts. This substitute requires PCB design compatibility with through hole mounting.

Both substitute parts are active products with established manufacturing and distribution channels, providing superior supply security compared to the obsolete 9C-6.000MAAJ-T.

Frequently Asked Questions (FAQ)

Q: Can the ABLS2-6.000MHZ-B4Y-T directly replace the 9C-6.000MAAJ-T without circuit modification?

A: Yes. Both parts operate at 6 MHz with ±30ppm frequency stability, 18pF load capacitance, and fundamental mode operation across the identical temperature range (-20°C to 70°C). Surface mount package compatibility and HC-49/US case specification ensure mechanical and electrical interchangeability. ESR difference (100 Ohms versus 80 Ohms) is within acceptable tolerance for standard oscillator circuits.

Q: What is the difference between the ABL-6.000MHZ-B4Y-T and ABLS2-6.000MHZ-B4Y-T?

A: The primary difference is mounting type. ABL-6.000MHZ-B4Y-T is through hole mounted, while ABLS2-6.000MHZ-B4Y-T is surface mount. Both maintain identical electrical specifications. Selection depends on PCB design and available footprint type. Surface mount (ABLS2) is recommended for new designs due to modern manufacturing standards.

Q: Does the ESR difference (80 Ohms versus 100 Ohms) affect circuit performance?

A: ESR variation of 20 Ohms is within standard tolerance for 6 MHz crystal applications. This difference does not affect frequency stability, load capacitance matching, or operating temperature performance. Circuit oscillator design typically accommodates ESR variations within this range without performance degradation.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both ABLS2-6.000MHZ-B4Y-T and ABL-6.000MHZ-B4Y-T are ROHS3 compliant, matching the original 9C-6.000MAAJ-T specification.

Q: What is the inventory status of substitute parts?

A: ABLS2-6.000MHZ-B4Y-T: 784 pieces in stock. ABL-6.000MHZ-B4Y-T: 936 pieces in stock. Both parts are manufactured by Abracon LLC with active product status, ensuring ongoing availability.

Q: Can the through hole ABL-6.000MHZ-B4Y-T be used in a surface mount design?

A: No. Through hole and surface mount parts require different PCB footprints and assembly processes. Use ABLS2-6.000MHZ-B4Y-T for surface mount applications.

Q: What is the physical dimension difference between the main part and substitutes?

A: All three parts conform to HC-49/US package specification. Minor dimensional variations exist: 9C-6.000MAAJ-T (11.40mm L x 4.80mm W, 4.10mm height), ABLS2-6.000MHZ-B4Y-T (11.40mm L x 4.70mm W, 3.30mm height), ABL-6.000MHZ-B4Y-T (11.50mm L x 5.00mm W, 3.50mm height). These variations remain within HC-49/US specification envelope and do not affect mechanical compatibility.
