AX7PBF2-156.2500C Equivalent & Substitute Parts

Part Overview

The AX7PBF2-156.2500C is a 156.25 MHz XO (Standard) LVPECL Oscillator manufactured by Abracon LLC as part of the ClearClock™ AX7 series. This surface mount crystal oscillator operates at 2.5V with Enable/Disable functionality and is housed in an 8-SMD, No Lead package measuring 7.00mm x 5.00mm. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AX7PBF2-156.2500C is determined by strict equivalence across the following critical parameters:

• Frequency: 156.25 MHz (exact match required)
• Output Type: LVPECL (exact match required)
• Supply Voltage: 2.5V (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: 7.00mm x 5.00mm (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitutes are grouped into two categories: Direct Manufacturer Substitutes (alternative manufacturers) and Parametric Equivalents (same manufacturer, alternative part variants).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring the AX7PBF2-156.2500C, the following selection criteria apply:

Abracon LLC Parametric Equivalents (AX7PBF1-156.2500C, AX7PBF3-156.2500C): These parts maintain identical electrical and mechanical specifications to the main part. Both are discontinued at DiGi Electronics but remain available through inventory channels. Selection between these variants should be based on internal design documentation and PCB layout compatibility, as they are direct parametric equivalents within the ClearClock™ AX7 series.

Taitien ODJMDLLTNF-156.250000: This part is an active product offering from an alternative manufacturer. It meets all critical electrical parameters and maintains ROHS3 compliance and MSL 1 rating. The maximum height is 0.073" (1.85mm) compared to 1.90mm for the Abracon variants, providing a marginal height advantage. Maximum disable current is specified at 95mA versus 86mA for Abracon parts. This substitute is suitable for new designs and ongoing procurement where manufacturer diversification is beneficial.

All substitutes maintain identical frequency, output type, supply voltage, function, frequency stability, operating temperature range, package type, and package dimensions as the main part.

Frequently Asked Questions (FAQ)

Q: Can ODJMDLLTNF-156.250000 be used as a direct replacement for AX7PBF2-156.2500C?

A: Yes. The Taitien ODJMDLLTNF-156.250000 meets all critical electrical and mechanical parameters required for substitution. Both parts operate at 156.25 MHz with LVPECL output, 2.5V supply, Enable/Disable function, ±25ppm frequency stability, and -40°C ~ 85°C operating temperature. Both are housed in 8-SMD, No Lead packages measuring 7.00mm x 5.00mm with ROHS3 compliance and MSL 1 rating.

Q: What is the difference between AX7PBF1-156.2500C, AX7PBF2-156.2500C, and AX7PBF3-156.2500C?

A: These three Abracon parts are parametric equivalents within the ClearClock™ AX7 series. All three share identical electrical specifications and package dimensions. The designations (PBF1, PBF2, PBF3) represent internal variant codes within Abracon's product line. Selection should be based on design documentation and PCB layout requirements.

Q: Are there any height considerations when substituting with ODJMDLLTNF-156.250000?

A: The Taitien ODJMDLLTNF-156.250000 has a maximum seated height of 1.85mm compared to 1.90mm for Abracon variants. This 0.05mm difference is negligible for most applications but should be verified against PCB clearance requirements and assembly specifications.

Q: Do all substitute parts have the same current consumption?

A: Maximum supply current is 94mA for Abracon parts and 95mA for the Taitien part. Maximum disable current is 86mA for Abracon parts and 95mA for the Taitien part. These differences are within typical operating margins and should not affect circuit design.

Q: Are all substitutes RoHS and REACH compliant?

A: All substitute parts are ROHS3 compliant. The Abracon parts carry REACH Unaffected status. Compliance documentation should be obtained from the respective manufacturers for specific application requirements.
