Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9C08070004 is determined by strict equivalence across the following critical parameters:

Primary Matching Criteria:

• Frequency: 8.0000 MHz (exact match required)
• Load Capacitance: 18pF (exact match required)
• Package / Case: HC-49/US (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Consideration:

• ESR (Equivalent Series Resistance): 80 Ohms is the primary specification; however, lower ESR values (50 Ohms) are electrically compatible and represent improved performance characteristics in circuit operation.

All substitute parts listed maintain full compatibility with the electrical and mechanical requirements of the original 9C08070004 specification. Substitutes are sourced from active product lines, ensuring long-term availability and supply chain reliability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Exact ESR Match - 80 Ohms):

The ABLS2-8.000MHZ-D4Y-T and ABLS3-8.000MHZ-D4Y-T from Abracon LLC, and the ECS-80-18-5PVX-GN-TR from ECS Inc. provide direct electrical equivalence to the 9C08070004. All three parts maintain the 80 Ohms ESR specification and are classified as Active products, ensuring sustained manufacturing and supply availability. These parts carry ROHS3 compliance and are suitable for immediate substitution in applications where the original 9C08070004 specification is required.

Secondary Substitutes (Lower ESR - 50 Ohms):

The J49SMH-F-G-G-K-8M0 and J49SML-F-G-G-K-8M0 from Jauch Quartz feature 50 Ohms ESR, representing a lower resistance characteristic than the original specification. Lower ESR values result in reduced power dissipation and improved frequency stability margins in oscillator circuits. These parts are electrically compatible with the 9C08070004 and are classified as Active products. Selection of these parts is appropriate when circuit design permits the improved ESR performance.

All substitute parts are ROHS3 compliant and carry EAR99 ECCN classification, matching the regulatory and compliance profile of the original component.

Frequently Asked Questions (FAQ)

Q: Can the ABLS2-8.000MHZ-D4Y-T and ABLS3-8.000MHZ-D4Y-T be used interchangeably with the 9C08070004?

A: Yes. Both Abracon parts maintain identical electrical specifications: 8 MHz frequency, ±30ppm stability, 18pF load capacitance, 80 Ohms ESR, and HC-49/US package. The primary difference is physical height: ABLS2 measures 0.130" (3.30mm) maximum seated height, while ABLS3 measures 0.098" (2.50mm). Verify PCB assembly clearance requirements before selection.

Q: What is the difference between the Jauch Quartz J49SMH-F-G-G-K-8M0 and J49SML-F-G-G-K-8M0?

A: Both parts are electrically identical with 50 Ohms ESR. The primary distinction is physical height: J49SMH measures 0.157" (4.00mm) maximum seated height, while J49SML measures 0.118" (3.00mm). Both are compatible with the 9C08070004 specification from an electrical standpoint.

Q: Why do some substitute parts have 50 Ohms ESR instead of 80 Ohms?

A: Lower ESR values represent improved component performance characteristics. The 50 Ohms ESR parts (Jauch Quartz models) are electrically compatible with circuits designed for 80 Ohms ESR. Lower ESR reduces power dissipation and can improve frequency stability. Circuit design verification is not required; these parts operate within the same frequency and load capacitance parameters.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 compliance certification, matching the environmental and regulatory status of the original 9C08070004.

Q: What is the significance of product status (Active vs. Obsolete)?

A: The 9C08070004 is classified as Obsolete, indicating discontinued manufacturing. All listed substitute parts are classified as Active, meaning they are currently manufactured and available through distribution channels. Active status ensures long-term supply chain reliability and supports ongoing production requirements.

Q: Can physical dimensions affect substitution suitability?

A: Physical dimensions must be verified against PCB assembly specifications and available mounting clearance. All substitute parts conform to the HC-49/US package standard. Height variations (ranging from 0.098" to 0.161" maximum seated height) require confirmation that PCB layout and component placement accommodate the selected part's physical profile.
