Substitute Part Grouping Explanation
Substitution eligibility for the 7M-10.000MAHI-T is determined by the following mandatory parameters:
Frequency Match: All substitute parts must operate at exactly 10.0000 MHz. Frequency deviation is not permissible.
Frequency Stability: Substitute parts must maintain ±30ppm stability or better. This specification is non-negotiable for circuit timing accuracy.
Operating Mode: All substitutes must operate in fundamental mode to ensure compatibility with oscillator circuit design.
Mounting and Package: Substitute parts must use surface mount technology with 4-SMD, No Lead package configuration and identical physical dimensions (3.20mm x 2.50mm) to ensure PCB footprint compatibility.
Temperature Range: Operating temperature range must encompass -40°C to 85°C minimum.
Compliance: RoHS compliance status must be maintained. MSL rating of 1 (Unlimited) is required.
Load Capacitance Consideration: While the main part specifies 16pF load capacitance, substitute parts with different load capacitance values (such as 12pF) are acceptable if the circuit design accommodates the alternative specification. Load capacitance affects oscillation frequency and must be verified against circuit requirements.

Engineering Selection Recommendations
Primary Substitution (7M-10.000MAHE-T):
The 7M-10.000MAHE-T is electrically and mechanically compatible with the 7M-10.000MAHI-T for applications where load capacitance specification permits. Both parts are manufactured by TXC CORPORATION within the active 7M series, maintain identical frequency, stability, ESR, temperature range, and physical dimensions.
The primary difference is load capacitance: 16pF (main part) versus 12pF (substitute). This parameter directly affects oscillation frequency and circuit tuning. Selection between these parts depends on circuit design specifications. If the circuit is designed for 16pF load capacitance, the 7M-10.000MAHE-T requires circuit verification before substitution.
Packaging Consideration:
The 7M-10.000MAHE-T is supplied in Tape & Reel (TR) format with significantly higher inventory availability (21,562 pcs) compared to the main part. This packaging format is standard for high-volume manufacturing and automated assembly processes.
Compliance Status:
Both parts maintain RoHS compliance and REACH unaffected status, suitable for regulated applications. MSL rating of 1 (Unlimited) eliminates moisture sensitivity concerns for both parts.
Product Status:
Both parts carry Active product status, ensuring continued manufacturer support and availability.
Frequently Asked Questions (FAQ)
Q: Can the 7M-10.000MAHE-T be used as a direct replacement for the 7M-10.000MAHI-T?
A: Physical and electrical compatibility exists for mounting and frequency generation. However, the load capacitance difference (12pF vs. 16pF) requires circuit verification. If your circuit design specifies 16pF load capacitance, substitution requires confirmation that the oscillator circuit can operate with 12pF load capacitance without frequency drift or startup issues.
Q: What is the significance of load capacitance in crystal oscillator selection?
A: Load capacitance is the capacitive load the crystal oscillator presents to the circuit. It affects the oscillation frequency and circuit tuning. Crystals are typically specified for a particular load capacitance value. Using a crystal with different load capacitance may result in frequency offset or oscillation instability if the circuit is not designed to accommodate the variation.
Q: Are both parts RoHS compliant?
A: Yes. Both the 7M-10.000MAHI-T and 7M-10.000MAHE-T are RoHS compliant and REACH unaffected, meeting regulatory requirements for restricted substance use.
Q: What is the difference between the packaging formats?
A: The main part (7M-10.000MAHI-T) packaging format is not specified in available data. The substitute part (7M-10.000MAHE-T) is supplied in Tape & Reel (TR) format, which is standard for automated pick-and-place assembly and high-volume production. Tape & Reel packaging provides better handling efficiency and cost economics for manufacturing operations.
Q: Do both parts have the same physical dimensions?
A: Yes. Both parts use identical 4-SMD, No Lead package with dimensions of 3.20mm x 2.50mm and maximum seated height of 0.80mm. PCB footprint compatibility is assured.
Q: What is MSL 1 (Unlimited) rating?
A: MSL (Moisture Sensitivity Level) 1 indicates the lowest moisture sensitivity classification. An Unlimited rating means the component can be stored indefinitely without special moisture control measures, simplifying inventory management and reducing handling costs.
Q: Are frequency stability specifications identical between both parts?
A: Yes. Both parts maintain ±30ppm frequency stability and ±30ppm frequency tolerance across the -40°C to 85°C operating temperature range.
Q: Which part should be selected for new designs?
A: For new designs, either part is acceptable provided the circuit design accommodates the load capacitance specification. The 7M-10.000MAHE-T offers higher inventory availability in Tape & Reel format, which is advantageous for manufacturing planning and supply chain management.
