Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M-16.000MAHV-T is determined by the following mandatory criteria:

Critical Parameters (Must Match Exactly):

• Frequency: 16.0000 MHz
• Frequency Stability: ±30 ppm minimum
• Operating Mode: Fundamental
• Operating Temperature Range: -40°C to 85°C minimum
• Mounting Type: Surface Mount
• Package Type: 4-SMD, No Lead
• Regulatory Compliance: RoHS Compliant or better

Design-Dependent Parameters (Variation Allowed):

• Load Capacitance: 8 pF baseline; substitutes with 10 pF are acceptable when circuit design accommodates the capacitive load difference
• ESR: 100 Ohms baseline; substitutes with higher ESR (up to 200 Ohms) are acceptable when circuit design margin permits

Inventory & Availability:

• Product Status: Active (ensures ongoing supply and support)
• Packaging: Tape & Reel (TR) standard for automated assembly

The 8Y-16.000MAHQ-T meets all critical parameters and is classified as a direct substitute with noted design considerations for load capacitance and ESR variations.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (7M-16.000MAHV-T): Select the 7M-16.000MAHV-T when the original design specifications call for 8 pF load capacitance and 100 Ohms ESR. This part maintains exact alignment with the circuit design parameters and requires no oscillator circuit modifications. The part is active with 12,100 pieces in stock, ensuring supply continuity.

Substitute Selection (8Y-16.000MAHQ-T): The 8Y-16.000MAHQ-T is substitutable when:

• The oscillator circuit design has sufficient margin to accommodate 10 pF load capacitance (2 pF increase from baseline)
• The oscillator circuit design has sufficient margin to accommodate 200 Ohms ESR (100 Ohms increase from baseline)
• PCB layout can accommodate the smaller 2.00mm × 1.60mm footprint
• The lower profile (0.55mm vs. 0.80mm) presents no mechanical interference

Both parts maintain identical frequency, stability, operating mode, temperature range, and mounting technology. Both are RoHS compliant and carry unlimited MSL ratings. The 8Y-16.000MAHQ-T achieves ROHS3 compliance, representing a higher regulatory standard. Inventory availability for the substitute is 3,494 pieces.

Regulatory & Compliance: Both parts are RoHS compliant, REACH unaffected, and classified under ECCN EAR99 and HTSUS 8541.60.0050. No additional compliance documentation is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can the 8Y-16.000MAHQ-T be used as a direct drop-in replacement for the 7M-16.000MAHV-T?

A: The 8Y-16.000MAHQ-T is electrically substitutable for the 7M-16.000MAHV-T with the following considerations: The load capacitance increases from 8 pF to 10 pF, and ESR increases from 100 Ohms to 200 Ohms. These changes require verification that the oscillator circuit design maintains adequate margin for stable operation. The smaller physical footprint (2.00mm × 1.60mm vs. 3.20mm × 2.50mm) requires PCB layout compatibility confirmation. If the original circuit was designed with minimal margin, oscillator circuit tuning or component adjustment may be necessary.

Q: What is the significance of load capacitance variation between these parts?

A: Load capacitance determines the frequency-setting network in the oscillator circuit. The 8Y-16.000MAHQ-T specifies 10 pF versus the 7M-16.000MAHV-T's 8 pF. This 2 pF difference affects the external capacitor values required for frequency calibration. Circuits designed with adequate capacitive tuning range can accommodate this variation. Circuits with minimal tuning range may experience frequency drift outside specification.

Q: Are there any temperature or environmental differences between these parts?

A: Both parts operate identically across the -40°C to 85°C temperature range with ±30 ppm frequency stability. Both carry MSL 1 (Unlimited) ratings, indicating no moisture sensitivity constraints. No environmental or thermal performance differences exist between the parts.

Q: What does the smaller physical size of the 8Y-16.000MAHQ-T mean for PCB design?

A: The 8Y-16.000MAHQ-T measures 2.00mm × 1.60mm compared to the 7M-16.000MAHV-T's 3.20mm × 2.50mm. The substitute is approximately 37% smaller in footprint area and 31% lower in profile (0.55mm vs. 0.80mm). PCB layouts must be verified for footprint compatibility. The smaller size may allow for more compact board designs but requires confirmation that the PCB pad pattern matches the substitute's dimensions.

Q: How do ESR differences affect circuit performance?

A: ESR (Equivalent Series Resistance) of 100 Ohms (main part) versus 200 Ohms (substitute) affects oscillator startup time and drive level requirements. Higher ESR increases the energy required to sustain oscillation. Oscillator circuits designed with adequate drive capability can tolerate the 100 Ohms increase. Circuits operating at minimum drive specifications may experience reduced oscillation margin or startup reliability with the higher ESR substitute.

Q: Are both parts actively manufactured?

A: Yes. Both the 7M-16.000MAHV-T and 8Y-16.000MAHQ-T are classified as Active products by TXC CORPORATION, ensuring ongoing manufacturing support and supply availability. Current inventory includes 12,100 pieces of the main part and 3,494 pieces of the substitute.

Q: What regulatory compliance applies to both parts?

A: Both parts are RoHS Compliant (the substitute achieves ROHS3 Compliant status, a higher standard). Both are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8541.60.0050. No additional regulatory documentation is required for substitution between these parts.
