Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7V-26.000MEDI-T is determined by the following critical parameters:

Primary Substitution Criteria:

• Frequency: 26.000 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -20°C to 70°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Load Capacitance: 12pF, 16pF, or 18pF (circuit-dependent; requires verification against application load requirements)
• ESR: 60 Ohms or 100 Ohms (circuit-dependent; requires verification against application impedance requirements)
• Physical Dimensions: Variations in length, width, and height permitted within PCB layout constraints
• Packaging Format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel® (logistics consideration; does not affect electrical performance)

The 7V-26.000MEDI-T has four identified substitute parts within the TXC CORPORATION product line. Three substitutes (7M-26.000MAAE-T, 7M-26.000MAAJ-T, 7V-26.000MAAE-T) maintain identical electrical specifications with variations in load capacitance. One substitute (8Y-26.000MAAJ-T) differs in ESR and physical dimensions.

Parameter Comparison

Engineering Selection Recommendations

7M-26.000MAAE-T (12pF Load Capacitance)

This substitute maintains identical electrical specifications to the 7V-26.000MEDI-T except for load capacitance (12pF vs. 16pF). Selection requires verification that the application circuit is designed for 12pF load capacitance. Physical dimensions are identical in length and width; seated height is 0.10mm lower (0.80mm vs. 0.90mm). All compliance certifications match. This part is available in higher inventory (8,460 pcs) and is packaged in Tape & Reel format.

7M-26.000MAAJ-T (18pF Load Capacitance)

This substitute maintains identical electrical specifications except for load capacitance (18pF vs. 16pF). Selection requires verification that the application circuit is designed for 18pF load capacitance. Physical dimensions are identical in length and width; seated height is 0.10mm lower (0.80mm vs. 0.90mm). All compliance certifications match. This part has the highest available inventory (72,509 pcs) and is available in both Cut Tape and Digi-Reel packaging formats.

7V-26.000MAAE-T (12pF Load Capacitance, Same Series)

This substitute is from the same 7V series as the main part and maintains identical electrical specifications except for load capacitance (12pF vs. 16pF). Selection requires verification that the application circuit is designed for 12pF load capacitance. Physical dimensions and seated height are identical to the main part. All compliance certifications match. This part is available in substantial inventory (30,846 pcs) and is packaged in Tape & Reel format.

8Y-26.000MAAJ-T (18pF Load Capacitance, Higher ESR)

This substitute differs in two electrical parameters: load capacitance (18pF vs. 16pF) and ESR (100 Ohms vs. 60 Ohms). Selection requires verification that the application circuit is designed for both 18pF load capacitance and 100 Ohm ESR. Physical dimensions are significantly smaller (2.00mm × 1.60mm vs. 3.20mm × 2.50mm) with lower seated height (0.55mm vs. 0.90mm). RoHS3 compliance exceeds the main part's RoHS compliance. This part is available in moderate inventory (7,075 pcs) and is packaged in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 7V-26.000MEDI-T with a part having different load capacitance?

A: Load capacitance substitution is permitted only when the application circuit is designed to operate at the substitute part's load capacitance value. The 7V-26.000MEDI-T operates at 16pF. Substitutes with 12pF or 18pF load capacitance require circuit verification. Incorrect load capacitance selection will result in frequency deviation beyond the ±30ppm specification.

Q: What is the difference between the 7M and 7V series crystals?

A: Both series maintain identical electrical specifications (26 MHz, ±30ppm, 60 Ohm ESR, -20°C to 70°C operating range). The primary difference is physical height: 7V series has a maximum seated height of 0.90mm, while 7M series has a maximum seated height of 0.80mm. Series selection depends on PCB layout constraints and available vertical clearance.

Q: Is the 8Y-26.000MAAJ-T a direct substitute?

A: The 8Y-26.000MAAJ-T is not a direct substitute. It differs in ESR (100 Ohms vs. 60 Ohms) and load capacitance (18pF vs. 16pF). Additionally, physical dimensions are significantly smaller (2.00mm × 1.60mm vs. 3.20mm × 2.50mm). This part is suitable only when the application circuit is specifically designed for 18pF load capacitance and 100 Ohm ESR, and when the smaller footprint is compatible with PCB layout.

Q: What packaging formats are available for these substitutes?

A: The 7V-26.000MEDI-T, 7M-26.000MAAE-T, 7V-26.000MAAE-T, and 8Y-26.000MAAJ-T are supplied in Tape & Reel (TR) format. The 7M-26.000MAAJ-T is available in both Cut Tape (CT) and Digi-Reel® formats. Packaging format does not affect electrical performance and is a logistics consideration for component handling and assembly processes.

Q: Are all substitute parts RoHS compliant?

A: Yes. The 7V-26.000MEDI-T and three substitute parts (7M-26.000MAAE-T, 7M-26.000MAAJ-T, 7V-26.000MAAE-T) are RoHS Compliant. The 8Y-26.000MAAJ-T is ROHS3 Compliant, which exceeds RoHS requirements. All parts are REACH Unaffected and classified as EAR99 for export control purposes.

Q: Can I use a substitute with different ESR in my circuit?

A: ESR substitution is permitted only when the application circuit is designed to operate at the substitute part's ESR value. The 7V-26.000MEDI-T operates at 60 Ohms ESR. The 8Y-26.000MAAJ-T operates at 100 Ohms ESR. Incorrect ESR selection will affect circuit performance, including frequency stability and startup characteristics. Circuit verification is required before substitution.

Q: What is the moisture sensitivity level for these crystals?

A: All parts listed (main part and substitutes) have MSL 1 (Unlimited) rating. This indicates the lowest moisture sensitivity classification, meaning these components have unlimited shelf life under normal storage conditions and do not require special moisture control during handling or storage.
