PBF620074Z Equivalent & Substitute Parts

Part Overview

The PBF620074Z is a 156.25 MHz XO (Standard) LVPECL oscillator manufactured by Diodes Incorporated. This crystal oscillator operates at 3.3V with Enable/Disable functionality, housed in a 6-SMD, No Lead package. The device is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same frequency, output type, voltage supply, and package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PBF620074Z are qualified based on strict equivalence of the following electrical and mechanical parameters:

• Frequency: 156.25 MHz (exact match required)
• Output: LVPECL (exact match required)
• Voltage Supply: 3.3V (exact match required)
• Function: Enable/Disable (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Temperature: -20°C ~ 70°C (exact match required)
• Package / Case: 6-SMD, No Lead (exact match required)
• Size / Dimension: 0.276" L x 0.197" W (7.00mm x 5.00mm) (exact match required)
• Mounting Type: Surface Mount (exact match required)

All identified substitutes meet these criteria and are therefore electrically and mechanically interchangeable with the PBF620074Z in applications requiring this specific oscillator configuration.

Parameter Comparison

Engineering Selection Recommendations

All three oscillators—PBF620074Z (Diodes Incorporated), OTETGCLTNF-156.250000 (Taitien), and SXO75P3A271-156.250M (Suntsu Electronics)—are Active products with RoHS3 compliance and EAR99 export classification. They are electrically and mechanically equivalent for 156.25 MHz LVPECL applications at 3.3V with Enable/Disable control.

Selection between these parts may be based on packaging availability (Tape & Reel, Cut Tape, or Bulk), current supply margin requirements (Taitien at 75mA maximum versus Diodes and Suntsu at 80mA), and height constraints for PCB assembly (Diodes at 1.55mm seated height offers the lowest profile, while Suntsu at 1.70mm offers the highest).

Frequently Asked Questions (FAQ)

Q: Can OTETGCLTNF-156.250000 replace PBF620074Z directly?

A: Yes. Both parts share identical electrical specifications (156.25 MHz, LVPECL, 3.3V, ±50ppm stability, -20°C to 70°C operation) and mechanical compatibility (6-SMD, No Lead package, 7.00mm x 5.00mm footprint). The Taitien part operates at 75mA maximum supply current versus 80mA for the Diodes part, which is acceptable for most applications. Height difference is 0.05mm (1.60mm vs 1.55mm), which is negligible for standard PCB assembly.

Q: Can SXO75P3A271-156.250M replace PBF620074Z directly?

A: Yes. The Suntsu part meets all electrical and mechanical requirements for direct substitution. Maximum supply current is 80mA (matching Diodes), and seated height is 1.70mm, which is 0.15mm higher than the Diodes part. This height difference must be verified against PCB clearance constraints in space-critical applications.

Q: What are the key differences between these three oscillators?

A: All three parts are functionally equivalent. Differences are limited to: (1) Packaging format (Tape & Reel, Cut Tape, or Bulk), (2) Maximum supply current (Taitien at 75mA vs. Diodes and Suntsu at 80mA), and (3) Seated height (Diodes 1.55mm, Taitien 1.60mm, Suntsu 1.70mm). These variations do not affect electrical performance or functional compatibility.

Q: Are there packaging or supply chain considerations?

A: Yes. PBF620074Z is supplied in Tape & Reel format (697 pcs in stock), OTETGCLTNF-156.250000 in Cut Tape format (1776 pcs in stock), and SXO75P3A271-156.250M in Bulk format (2518 pcs in stock). Selection may depend on procurement volume and assembly line requirements.

Q: Do all parts meet regulatory compliance?

A: Yes. All three oscillators are RoHS3 compliant and classified as EAR99 for export purposes. Diodes and Taitien parts are REACH Unaffected. Moisture Sensitivity Level is 1 (Unlimited) for Diodes and Taitien parts.
