Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BA-156.250MBE-T is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• 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: ±50ppm (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Package Type: 6-SMD, No Lead (exact match required)
• Physical Dimensions: 7.00mm L x 5.00mm W (exact match required)
• Mounting Type: Surface Mount (exact match required)

Allowable Variation Parameters:

• Current Supply (Max): Variation permitted within component design limits
• Height - Seated (Max): Minor variation permitted (within 0.020" tolerance)
• Packaging Format: Tape & Reel or Bulk acceptable
• Manufacturer: Different manufacturers acceptable if all electrical and mechanical specifications align

All three substitute parts listed meet these mandatory matching criteria and are therefore direct functional equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the BA-156.250MBE-T and meet identical electrical and mechanical specifications. Selection among these alternatives should be based on the following factors:

PB223-156.25M (Connor Winfield): This substitute offers the lowest maximum supply current at 50mA, providing potential power efficiency advantages in applications where current consumption is a design constraint. The part is ROHS3 Compliant and REACH Unaffected, with 3410 units in stock. Height is 1.47mm, the lowest among all options, suitable for space-constrained PCB layouts.

SG7050EEN 156.2500M-CJGA3 (EPSON): This substitute specifies a maximum disable current of 25mA, providing defined power consumption during disabled operation. The part is ROHS3 Compliant and REACH Unaffected, with 1727 units in stock. Height is 1.70mm. This specification is relevant for applications requiring precise power management during standby states.

SXO75P3A481-156.250M (Suntsu): This substitute matches the original part's maximum supply current at 80mA and is available in Bulk packaging. The part is ROHS3 Compliant, with 2565 units in stock. Height is 1.70mm. This option provides inventory availability and maintains identical current specifications to the original.

All parts carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications, ensuring consistent regulatory treatment.

Frequently Asked Questions (FAQ)

Q: Can PB223-156.25M be used as a direct replacement for BA-156.250MBE-T?

A: Yes. The PB223-156.25M meets all mandatory electrical and mechanical specifications: 156.25 MHz frequency, LVPECL output, 3.3V supply, Enable/Disable function, ±50ppm stability, -40°C to 85°C operating range, and 6-SMD No Lead package with 7.00mm x 5.00mm dimensions. The lower maximum supply current (50mA vs 80mA) represents an allowable variation that does not prevent substitution.

Q: What is the significance of the height difference between substitute parts?

A: The BA-156.250MBE-T has a maximum seated height of 1.50mm. The PB223-156.25M is 1.47mm, while both the SG7050EEN and SXO75P3A481-156.250M are 1.70mm. These variations fall within typical PCB design tolerances for surface mount components. Height differences may impact clearance in applications with space constraints above the component, but do not affect electrical functionality or pin compatibility.

Q: Are there packaging differences between these substitute parts?

A: The BA-156.250MBE-T and PB223-156.25M are supplied in Tape & Reel (TR) format. The SXO75P3A481-156.250M is supplied in Bulk packaging. The SG7050EEN is supplied in Tape & Reel format. Packaging format does not affect component functionality or electrical performance; it relates only to order quantity and handling logistics.

Q: What does the disable current specification mean for SG7050EEN?

A: The SG7050EEN specifies a maximum supply current of 25mA during disabled operation. This parameter is not specified for the other parts. In applications where the oscillator Enable/Disable function is used to manage power consumption, this specification indicates the quiescent current draw when the output is disabled. This information is useful for power budget calculations in low-power applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. The BA-156.250MBE-T is RoHS Compliant. All three substitute parts are ROHS3 Compliant, which represents a more recent revision of the RoHS standard. ROHS3 Compliant parts are acceptable replacements for RoHS Compliant applications.

Q: Do these parts have identical regulatory classifications?

A: Yes. All parts, including the original BA-156.250MBE-T and all three substitutes, carry identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. This ensures consistent regulatory treatment and export compliance across all options.

Q: Can I mix these parts within a single production run?

A: Yes. Since all parts meet identical electrical and mechanical specifications for the critical parameters that determine circuit functionality, they are interchangeable. However, standard manufacturing practices recommend maintaining consistent component sourcing within a single production batch to ensure traceability and consistency in quality documentation.
