Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the AX3DAF3-156.2500T are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Critical Matching Parameters:

• Frequency: 156.25 MHz (exact match required)
• Output Type: LVDS (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 / Case: 6-SMD, No Lead (exact match required)
• Physical Dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

All identified substitute parts meet these criteria. Variations in current supply specifications, packaging format (Tape & Reel vs. Cut Tape), and height-seated measurements do not affect functional substitution within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts are Active products with ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity ratings, meeting the same regulatory and environmental standards as the primary part AX3DAF3-156.2500T.

AX3DAF1-156.2500T3 (Abracon LLC): Parametric equivalent within the same ClearClock™ AX3 series. Identical electrical specifications and physical dimensions. Packaging format is Tape & Reel (TR) versus the primary part's standard packaging. Higher inventory availability (1604 pcs) supports extended lead time requirements.

NX3231D0156.250000 (Diodes Incorporated): Direct manufacturer equivalent from the SaRonix-eCera™ NX series. Meets all critical electrical and mechanical parameters. Maximum supply current is 70mA compared to 27mA for the primary part; this represents higher power consumption during operation. Height-seated measurement is 0.041" (1.05mm), which is 0.002" lower than the primary part. Highest inventory availability (3936 pcs) supports immediate sourcing needs.

SG3225VEN 156.250000M-CDGA3 (EPSON): Direct manufacturer equivalent from the SG3225VEN series. Meets all critical electrical and mechanical parameters. Maximum supply current is 25mA, closest to the primary part's 27mA specification. Height-seated measurement is 0.047" (1.20mm), which is 0.004" higher than the primary part. Packaging format is Cut Tape (CT) & Digi-Reel®. Inventory availability (2799 pcs) supports standard sourcing timelines.

Frequently Asked Questions (FAQ)

Q: Can AX3DAF1-156.2500T3 be used as a direct replacement for AX3DAF3-156.2500T?

A: Yes. Both parts are from the Abracon LLC ClearClock™ AX3 series with identical electrical specifications, frequency stability, operating temperature range, and physical dimensions. The primary difference is packaging format (Tape & Reel vs. standard packaging). Functional substitution is direct.

Q: What is the impact of different maximum supply current ratings among substitute parts?

A: The primary part AX3DAF3-156.2500T specifies 27mA maximum supply current. The NX3231D0156.250000 specifies 70mA, while SG3225VEN 156.250000M-CDGA3 specifies 25mA. These variations reflect manufacturer design differences but do not affect functional compatibility. Circuit design must accommodate the actual current draw of the selected part during operation and disable mode.

Q: Are there physical clearance concerns with height-seated variations?

A: Height-seated measurements vary slightly: AX3DAF3-156.2500T and AX3DAF1-156.2500T3 are 0.043" (1.10mm), NX3231D0156.250000 is 0.041" (1.05mm), and SG3225VEN 156.250000M-CDGA3 is 0.047" (1.20mm). These variations are within typical PCB assembly tolerances for 6-SMD, No Lead packages. Verify clearance with specific board layout requirements.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 with HTSUS code 8542.39.0001. All parts have MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What packaging formats are available for these substitute parts?

A: AX3DAF3-156.2500T uses standard packaging. AX3DAF1-156.2500T3 is supplied in Tape & Reel (TR) format. NX3231D0156.250000 is supplied in Tape & Reel (TR) format. SG3225VEN 156.250000M-CDGA3 is supplied in Cut Tape (CT) & Digi-Reel® format. Packaging selection depends on assembly process requirements and order quantity.

Q: Are all substitute parts currently in active production?

A: Yes. All parts maintain Active product status with current inventory availability: AX3DAF3-156.2500T (754 pcs), AX3DAF1-156.2500T3 (1604 pcs), NX3231D0156.250000 (3936 pcs), and SG3225VEN 156.250000M-CDGA3 (2799 pcs).
