9C10070006 Crystal 10.0000MHz 18pF SMD Equivalent & Substitute Parts

Part Overview

The 9C10070006 is a 10 MHz surface mount crystal manufactured by TXC CORPORATION, designed for applications requiring precise frequency generation with 18pF load capacitance and 40 Ohms equivalent series resistance. This component operates across the -20°C to 70°C temperature range with ±10ppm frequency stability.

The 9C10070006 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for systems utilizing this frequency standard.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 9C10070006 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Frequency: 10 MHz
• Frequency Stability: ±10ppm
• Load Capacitance: 18pF
• Package / Case: HC-49/US
• Operating Temperature Range: -20°C ~ 70°C
• RoHS Compliance: ROHS3 Compliant

Allowable Variation Parameters:

• ESR (Equivalent Series Resistance): Substitute parts may have ESR values within the range of 40-50 Ohms, provided circuit design accommodates the specified tolerance
• Mounting Type: Surface mount substitutes are prioritized; through-hole variants are listed for reference but require board redesign
• Moisture Sensitivity Level: MSL 1 or Not Applicable are acceptable

Two substitute parts meet these criteria: the ABL-10.000MHZ-B1U-T (through-hole variant) and the ABLS2-10.000MHZ-B1U-T (surface mount variant). The ABLS2-10.000MHZ-B1U-T is the primary substitute due to matching mounting type.

Engineering Selection Recommendations

Primary Substitute: ABLS2-10.000MHZ-B1U-T

The ABLS2-10.000MHZ-B1U-T is the recommended substitute for the 9C10070006. This part maintains surface mount compatibility, matching the original mounting type and eliminating the need for board redesign. All critical electrical parameters align: 10 MHz frequency, ±10ppm stability, and 18pF load capacitance. The ESR specification of 50 Ohms represents a 10 Ohm increase from the original 40 Ohms; this variation is within acceptable tolerances for standard crystal oscillator circuit designs. The ABLS2-10.000MHZ-B1U-T is currently in active production status with 879 pieces available in inventory. ROHS3 compliance and REACH affected status match the regulatory profile of the original component.

Secondary Substitute: ABL-10.000MHZ-B1U-T

The ABL-10.000MHZ-B1U-T provides an alternative substitute with identical electrical specifications. However, this part is configured for through-hole mounting, requiring circuit board redesign and assembly process modification. The ABL-10.000MHZ-B1U-T is suitable only when board layout changes are feasible. This part is currently in active production with 886 pieces available in inventory and maintains ROHS3 compliance.

Both substitute parts are manufactured by Abracon LLC, an established supplier of frequency control components, and carry the same ECCN and HTSUS classifications as the original part.

Frequently Asked Questions (FAQ)

Q: Can the ABLS2-10.000MHZ-B1U-T directly replace the 9C10070006 without circuit modification?

A: Yes. The ABLS2-10.000MHZ-B1U-T maintains surface mount configuration and all critical electrical parameters. The 10 Ohm ESR increase (from 40 to 50 Ohms) is within standard design tolerances for 10 MHz crystal circuits. No board redesign is required.

Q: What is the significance of the ESR difference between the main part and substitutes?

A: ESR (Equivalent Series Resistance) affects crystal circuit startup time and power consumption. The 9C10070006 specifies 40 Ohms, while both Abracon substitutes specify 50 Ohms. This 25% increase is acceptable for most applications; however, designs with marginal oscillator drive levels should verify circuit performance during qualification testing.

Q: Why is the ABL-10.000MHZ-B1U-T listed as a secondary option?

A: The ABL-10.000MHZ-B1U-T is a through-hole component, while the original 9C10070006 is surface mount. Substitution requires board layout modification and assembly process changes. The ABLS2-10.000MHZ-B1U-T eliminates these requirements by maintaining surface mount compatibility.

Q: Are there differences in physical dimensions between the main part and substitutes?

A: Minor dimensional variations exist within the HC-49/US package specification. The 9C10070006 measures 0.449" L x 0.189" W with 0.161" maximum seated height. The ABLS2-10.000MHZ-B1U-T measures 0.449" L x 0.185" W with 0.130" maximum seated height. These variations remain within package tolerance and do not affect mechanical compatibility.

Q: What is the difference between ROHS3 Compliant and REACH Affected status?

A: ROHS3 Compliant indicates the component meets Restriction of Hazardous Substances Directive requirements. REACH Affected indicates the component contains substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations. Both the main part and ABLS2-10.000MHZ-B1U-T carry these designations; the ABL-10.000MHZ-B1U-T is REACH Unaffected.

Q: Is the Moisture Sensitivity Level (MSL) difference between parts significant?

A: The 9C10070006 and ABL-10.000MHZ-B1U-T specify MSL 1 (Unlimited), indicating no moisture sensitivity. The ABLS2-10.000MHZ-B1U-T specifies MSL Not Applicable. This difference does not affect handling or storage requirements for either component.

Q: What inventory status should influence part selection?

A: The ABLS2-10.000MHZ-B1U-T has 879 pieces in stock, and the ABL-10.000MHZ-B1U-T has 886 pieces in stock. Both substitutes maintain adequate inventory for production requirements. The original 9C10070006 has 711 pieces available but is obsolete and should not be specified for new designs.
