Substitute Part Grouping Explanation

Substitute parts for the AX7PAF4-156.2500C are qualified based on the following critical parameters that must match or be compatible:

• Frequency: 156.25 MHz (exact match required)
• Output Type: LVPECL (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±25ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 8-SMD, No Lead (exact match required)
• Package Dimensions: 0.276" L x 0.197" W / 7.00mm x 5.00mm (exact match required)
• Mounting Type: Surface Mount (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All substitute parts listed below meet these criteria and are electrically and mechanically interchangeable with the main part.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the AX7PAF4-156.2500C and meet identical compliance requirements.

Active Status Parts: ODEMDLLTNF-156.250000 (Taitien) and XPP736156.250000I (Renesas Electronics Corporation) are currently active products with confirmed inventory availability. These parts are recommended for new procurement and ongoing system support due to their active status and supply chain availability.

Compliance Alignment: All substitute parts maintain ROHS3 compliance, EAR99 export classification, and identical HTSUS coding. All parts feature Moisture Sensitivity Level 1 (Unlimited), eliminating special handling requirements.

Parametric Equivalence: The AX7PAF3-156.2500C (Abracon LLC) is a parametric equivalent within the same manufacturer's ClearClock™ AX7 series. Although discontinued at DiGi Electronics, it shares identical electrical and mechanical specifications with the main part.

Supply Current Consideration: The ODEMDLLTNF-156.250000 (Taitien) specifies maximum supply current of 110mA compared to 94mA for the AX7PAF4-156.2500C. This higher current specification does not affect compatibility but should be considered in power budget calculations for applications with tight power constraints.

Frequently Asked Questions (FAQ)

Q: Can ODEMDLLTNF-156.250000 be used as a direct replacement for AX7PAF4-156.2500C?

A: Yes. Both parts operate at 156.25 MHz with LVPECL output, 3.3V supply, Enable/Disable function, ±25ppm frequency stability, and identical package dimensions (7.00mm x 5.00mm, 8-SMD No Lead). The ODEMDLLTNF-156.250000 specifies 110mA maximum supply current versus 94mA for the AX7PAF4-156.2500C, but this does not prevent direct substitution.

Q: What is the difference between XPP736156.250000I and the main part?

A: The XPP736156.250000I (Renesas) is electrically and mechanically equivalent. It meets all critical parameters: 156.25 MHz frequency, LVPECL output, 3.3V supply, Enable/Disable function, ±25ppm stability, and identical package specifications. Supply current specifications are not provided for the Renesas part.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and meet identical environmental and regulatory requirements as the AX7PAF4-156.2500C.

Q: Can the AX7PAF3-156.2500C be used in place of the AX7PAF4-156.2500C?

A: Yes. The AX7PAF3-156.2500C is a parametric equivalent from Abracon LLC's ClearClock™ AX7 series with identical electrical specifications, frequency stability, operating temperature range, and package dimensions. Both parts are discontinued at DiGi Electronics.

Q: What are the package compatibility considerations?

A: All substitute parts use the same 8-SMD, No Lead package with 7.00mm x 5.00mm footprint and surface mount mounting type. Height specifications vary slightly: AX7PAF4-156.2500C and AX7PAF3-156.2500C specify 0.075" (1.90mm) maximum seated height, while ODEMDLLTNF-156.250000 specifies 0.073" (1.85mm). These minor height differences do not affect PCB assembly compatibility.

Q: Which substitute part has the best supply availability?

A: XPP736156.250000I (Renesas Electronics Corporation) has 1672 pieces in stock. ODEMDLLTNF-156.250000 (Taitien) has 849 pieces in stock. Both are active products with confirmed availability.
