Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7M-26.000MDHV-T is determined by the following critical parameters:

Primary Matching Criteria:

• Frequency: 26 MHz (exact match required)
• Frequency Tolerance: ±20ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Load Capacitance: 8pF (primary specification; 10pF variants acceptable with circuit design verification)
• ESR: 60 Ohms (primary specification; lower ESR values acceptable; higher values require evaluation)
• Physical Dimensions: 3.20mm × 2.50mm (primary specification; smaller packages acceptable; larger packages require PCB layout verification)

Substitute parts must maintain identical frequency, tolerance, operating mode, temperature range, and package type. Variations in load capacitance, ESR, and physical dimensions are permissible within engineering design constraints.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Highest Compatibility):

The ECS-260-8-33-JGN-TR manufactured by ECS Inc. provides the closest electrical and mechanical match to the 7M-26.000MDHV-T. Both parts share identical frequency, tolerance, stability, load capacitance (8pF), operating temperature range, package type, and physical dimensions (3.20mm × 2.50mm × 0.80mm). The ECS part features lower ESR (40 Ohms versus 60 Ohms), which is advantageous for circuit performance. Both parts maintain RoHS3 compliance and MSL 1 rating. Current inventory of 5,224 units provides supply security.

Compatible Substitutes (Load Capacitance Variation):

The ABM10-26.000MHZ-D30-T3 (Abracon LLC) and IXA12-HF5F10-26.000MHZ (ILSI) are compatible substitutes with load capacitance specified at 10pF instead of 8pF. Both maintain identical frequency, tolerance, stability, operating temperature range, and package type. The ABM10 variant matches the primary package dimensions (3.20mm × 2.50mm) with reduced height (0.70mm). The IXA12 variant features a smaller footprint (2.00mm × 1.60mm × 0.55mm) with lower profile. Both parts carry ROHS3 compliance. The IXA12 includes AEC-Q200 automotive qualification. Load capacitance variation requires circuit design verification to confirm oscillator startup and frequency accuracy within system tolerance.

Selection Criteria:

• Identical Specifications Required: Select ECS-260-8-33-JGN-TR
• Smaller Footprint Acceptable: Select IXA12-HF5F10-26.000MHZ
• Automotive Qualification Required: Select IXA12-HF5F10-26.000MHZ
• Standard Package Footprint with Load Capacitance Tolerance: Select ABM10-26.000MHZ-D30-T3

All substitute parts maintain Active product status and current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can the ECS-260-8-33-JGN-TR replace the 7M-26.000MDHV-T without circuit modification?

A: Yes. The ECS-260-8-33-JGN-TR is a direct equivalent with identical frequency (26 MHz), tolerance (±20ppm), load capacitance (8pF), operating temperature range (-40°C to 85°C), and package dimensions (3.20mm × 2.50mm × 0.80mm). The lower ESR (40 Ohms) improves circuit performance. No circuit modification is required.

Q: What is the impact of using a 10pF load capacitance crystal instead of 8pF?

A: Load capacitance affects oscillator startup behavior and frequency accuracy. Crystals specified at 10pF require different load capacitance values in the oscillator circuit compared to 8pF designs. Circuit design verification is necessary to confirm oscillator startup margin and frequency accuracy remain within system tolerance. The ABM10-26.000MHZ-D30-T3 and IXA12-HF5F10-26.000MHZ both specify 10pF load capacitance.

Q: Can the IXA12-HF5F10-26.000MHZ be used in place of the 7M-26.000MDHV-T on the same PCB?

A: The IXA12 features a smaller footprint (2.00mm × 1.60mm) compared to the primary part (3.20mm × 2.50mm). PCB layout verification is required to confirm the smaller package is compatible with existing pad patterns and routing. The 10pF load capacitance also requires circuit design verification. Physical compatibility depends on PCB design flexibility.

Q: What is the difference between RoHS and ROHS3 compliance?

A: Both designations indicate compliance with Restriction of Hazardous Substances regulations. RoHS Compliant and ROHS3 Compliant both confirm the absence of restricted substances. All substitute parts meet current compliance requirements.

Q: Does MSL (Moisture Sensitivity Level) affect substitution eligibility?

A: MSL rating indicates moisture sensitivity during storage and handling. The 7M-26.000MDHV-T and most substitutes carry MSL 1 (Unlimited), indicating minimal moisture sensitivity. The ABM10-26.000MHZ-D30-T3 lists MSL as Not Applicable, indicating no moisture sensitivity concern. All parts are suitable for standard handling and storage procedures.

Q: Which substitute part offers the best supply availability?

A: The ECS-260-8-33-JGN-TR provides the highest current inventory at 5,224 units, followed by the IXA12-HF5F10-26.000MHZ at 3,774 units and the ABM10-26.000MHZ-D30-T3 at 1,727 units. The primary part (7M-26.000MDHV-T) maintains 1,158 units in stock.

Q: Is AEC-Q200 qualification required for this application?

A: AEC-Q200 qualification is an automotive industry standard. The IXA12-HF5F10-26.000MHZ carries this certification; other parts do not. Select the IXA12 variant only if automotive qualification is a system requirement.
