Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ABLS-6.000MHZ-K4T is determined by strict equivalence in the following parameters:

• Frequency: 6 MHz (exact match required)
• Frequency Tolerance: ±30ppm (exact match required)
• Load Capacitance: 18pF (exact match required)
• ESR: 100 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)

All qualified substitutes maintain these core electrical and mechanical specifications. Variations in operating temperature range, frequency stability, physical height, and series designation do not preclude substitution when the above parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active product status and are manufactured by Abracon LLC. The ABLS-6.000MHZ-K4T, ABLS-6.000MHZ-B4-T, and ABLS-6.000MHZ-L4Q-T variants are ROHS3 Compliant. The ABLS2-6.000MHZ-D4Y-T and ABLS3-6.000MHZ-D4Y-T are also compliant with ROHS3 and ROHS Unaffected respectively.

Selection between substitutes depends on application-specific requirements for operating temperature range and physical height constraints. The ABLS3-6.000MHZ-D4Y-T offers the lowest profile at 0.098" (2.50mm) maximum seated height. The ABLS-6.000MHZ-L4Q-T provides the widest operating temperature range from -55°C to 125°C. All parts are packaged in Tape & Reel format and maintain identical electrical performance for the specified 6 MHz frequency with ±30ppm tolerance.

Frequently Asked Questions (FAQ)

Q: Can ABLS-6.000MHZ-B4-T replace ABLS-6.000MHZ-K4T in all applications?

A: ABLS-6.000MHZ-B4-T is electrically equivalent but operates within -20°C to 70°C temperature range compared to the main part's -40°C to 125°C. Substitution is valid only when the application operates within the narrower temperature window.

Q: What is the primary difference between ABLS2-6.000MHZ-D4Y-T and ABLS3-6.000MHZ-D4Y-T?

A: Both parts are electrically identical with 6 MHz frequency and ±30ppm tolerance. The ABLS3 variant has a lower profile height of 0.098" (2.50mm) versus 0.130" (3.30mm) for ABLS2, and differs in REACH compliance status.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes, all listed substitute parts are supplied in Tape & Reel (TR) packaging format.

Q: Does ABLS-6.000MHZ-L4Q-T have different electrical performance?

A: ABLS-6.000MHZ-L4Q-T maintains identical frequency tolerance (±30ppm) and load capacitance (18pF). Frequency stability is ±100ppm compared to ±50ppm for the main part, but this does not affect substitution eligibility based on the specified parameters.

Q: Are all parts ROHS compliant?

A: All substitute parts meet ROHS requirements. ABLS-6.000MHZ-K4T, ABLS-6.000MHZ-B4-T, ABLS-6.000MHZ-L4Q-T, and ABLS2-6.000MHZ-D4Y-T are ROHS3 Compliant. ABLS3-6.000MHZ-D4Y-T is ROHS Unaffected.
