ABLS-8.000MHZ-D-4-H-T Equivalent & Substitute Parts

Part Overview

The ABLS-8.000MHZ-D-4-H-T is an 8 MHz fundamental mode crystal oscillator manufactured by Abracon LLC, designed for surface mount applications in the HC-49/US package. This active product features 18pF load capacitance and 80 Ohms equivalent series resistance, operating across the -40°C to 85°C temperature range. Alternative models may be required due to inventory constraints, specific load capacitance requirements in circuit design, or application-specific frequency stability needs.

Key Parameters

Substitute Part Grouping Explanation

The ABLS-8.000MHZ-16-D-4-H-T qualifies as a direct substitute based on the following critical parameters:

• Frequency Match: Both parts operate at 8 MHz with identical ±30ppm frequency tolerance
• ESR Match: Both parts maintain 80 Ohms equivalent series resistance
• Operating Mode: Both operate in fundamental mode
• Temperature Range: Both support -40°C to 85°C operation
• Package Compatibility: Both use HC-49/US surface mount package with identical physical dimensions (11.40mm x 4.70mm x 4.20mm max height)
• Compliance Alignment: Both are ROHS3 compliant and REACH affected

The primary difference is load capacitance: the substitute part specifies 16pF versus the main part's 18pF. This 2pF variance falls within acceptable substitution parameters for crystal oscillator applications where load capacitance tolerance is typically managed through external circuit design.

Parameter Comparison

Engineering Selection Recommendations

Both the ABLS-8.000MHZ-D-4-H-T and ABLS-8.000MHZ-16-D-4-H-T are active products from Abracon LLC with full ROHS3 compliance and REACH compliance status. Selection between these parts should be based on circuit-specific load capacitance requirements. The 18pF load capacitance specification of the main part may be preferred in designs where external load capacitance is calibrated to this value. The 16pF substitute part is suitable for applications where the 2pF difference can be accommodated through circuit tuning or where the lower load capacitance specification aligns with system requirements. Both parts maintain identical frequency tolerance, ESR, temperature range, and physical package specifications, ensuring mechanical and thermal compatibility in surface mount applications.

Frequently Asked Questions (FAQ)

Q: Can ABLS-8.000MHZ-16-D-4-H-T replace ABLS-8.000MHZ-D-4-H-T in existing designs?

A: Yes, provided the circuit design accommodates the 16pF load capacitance specification. The substitute part maintains identical frequency tolerance (±30ppm), ESR (80 Ohms), operating temperature range (-40°C to 85°C), and physical package dimensions. Load capacitance differences are typically managed through external circuit design rather than crystal selection.

Q: Are there physical compatibility concerns between these parts?

A: No. Both parts use the HC-49/US surface mount package with identical dimensions (11.40mm x 4.70mm) and maximum seated height (4.20mm). They are mechanically interchangeable on PCBs designed for this package type.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both ABLS-8.000MHZ-D-4-H-T and ABLS-8.000MHZ-16-D-4-H-T are ROHS3 compliant and REACH affected, meeting identical regulatory standards.

Q: What is the significance of the load capacitance difference?

A: Load capacitance (18pF vs. 16pF) affects the crystal's frequency response when combined with external circuit capacitance. The 2pF difference is typically compensated through circuit design. Both parts operate at the same 8 MHz fundamental frequency with identical ±30ppm tolerance.

Q: Are both parts currently available?

A: Yes. Both parts maintain active product status with current inventory: ABLS-8.000MHZ-D-4-H-T (1045 pcs) and ABLS-8.000MHZ-16-D-4-H-T (1346 pcs).
