Substitute Part Grouping Explanation

Substitution eligibility for the ASE-26.000MHZ-L-C-T is determined by strict equivalence across the following critical parameters:

• Frequency: 26 MHz (exact match required)
• Output Configuration: CMOS output with enable/disable function
• Supply Voltage: 3.3V operation
• Frequency Stability: ±50ppm tolerance
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 4-SMD, No Lead surface mount
• Physical Dimensions: 3.20mm x 2.50mm footprint with 1.20mm maximum height
• Environmental Compliance: ROHS3 Compliant

The LFSPXO027167 manufactured by IQD Frequency Products meets all substitution criteria and is classified as a parametric equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the ASE-26.000MHZ-L-C-T and LFSPXO027167 are active production components with full ROHS3 compliance. Selection between these parts should be based on:

Supply chain availability and lead time requirements. The ASE-26.000MHZ-L-C-T currently has 1058 units in stock, while the LFSPXO027167 has 1610 units available.

Maximum supply current specification. The LFSPXO027167 operates at 12mA maximum supply current compared to 13mA for the ASE-26.000MHZ-L-C-T, representing a marginal reduction in power consumption.

Manufacturer preference and qualification requirements within your design documentation and supply chain procedures.

Both parts are electrically and mechanically interchangeable within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the LFSPXO027167 be used as a direct replacement for the ASE-26.000MHZ-L-C-T?

A: Yes. Both parts share identical electrical specifications (26 MHz frequency, CMOS output, 3.3V supply, ±50ppm stability, -40°C ~ 85°C operating range) and mechanical compatibility (4-SMD, No Lead package, 3.20mm x 2.50mm footprint, 1.20mm maximum height). No circuit modifications are required.

Q: Are there any differences in power consumption between these parts?

A: The LFSPXO027167 specifies a maximum supply current of 12mA, while the ASE-26.000MHZ-L-C-T specifies 13mA. This 1mA difference is negligible for most applications and does not affect functional compatibility.

Q: Do both parts meet the same environmental compliance standards?

A: Yes. Both the ASE-26.000MHZ-L-C-T and LFSPXO027167 are ROHS3 compliant. The LFSPXO027167 additionally carries REACH Unaffected status and EAR99 export classification.

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

A: The ASE-26.000MHZ-L-C-T is rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The LFSPXO027167 is listed as Not Applicable for MSL, which is consistent with MSL 1 classification.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. Both parts use identical 4-SMD, No Lead surface mount packaging with matching footprint dimensions (3.20mm x 2.50mm) and height (1.20mm). No PCB layout modifications are necessary for substitution.
