Engineering Selection Recommendations
All three parts—AK2DBF2-156.2500, AK2DBF1-156.2500, and AK2DCF1-156.2500—are Active products from Abracon LLC with ROHS3 compliance and REACH Unaffected status. Selection between these parts depends on system voltage supply requirements:
AK2DBF2-156.2500 and AK2DBF1-156.2500 are functionally equivalent, both operating at 2.5V supply voltage. The primary difference is packaging configuration. Both maintain identical electrical and mechanical specifications.
AK2DCF1-156.2500 operates at 1.8V supply voltage and is suitable for systems requiring lower voltage operation. All other electrical and mechanical parameters remain identical to the 2.5V variants.
Component selection should be based on the system's power supply voltage specification. All parts maintain the same frequency stability, temperature range, and output characteristics necessary for 156.25 MHz LVDS applications.
Frequently Asked Questions (FAQ)
Q: Can AK2DCF1-156.2500 (1.8V) be used as a direct replacement for AK2DBF2-156.2500 (2.5V)?
A: No. The supply voltage difference requires circuit-level compatibility verification. The 1.8V variant is only suitable for systems designed to operate at 1.8V supply. Using it in a 2.5V circuit will result in improper operation.
Q: Are AK2DBF2-156.2500 and AK2DBF1-156.2500 interchangeable?
A: Yes. Both parts operate at 2.5V supply voltage and maintain identical electrical and mechanical specifications. The difference is packaging configuration (standard vs. bulk). They are parametric equivalents suitable for direct substitution in 2.5V applications.
Q: What determines substitutability between these oscillators?
A: Substitutability is determined by matching frequency (156.25 MHz), output type (LVDS), supply voltage, package type (6-SMD, No Lead), physical dimensions, and operating temperature range (-40°C ~ 85°C). All three parts share these core specifications with voltage supply as the primary variable parameter.
Q: Does packaging type affect electrical performance?
A: No. Packaging type (standard vs. bulk) does not affect electrical performance. It relates only to order quantity and delivery format. Electrical specifications remain identical regardless of packaging configuration.
Q: Are all three parts suitable for high-reliability applications?
A: All three parts are Active products with ROHS3 compliance, MSL 1 (Unlimited) moisture sensitivity rating, and REACH Unaffected status. Selection for high-reliability applications should be based on system voltage requirements and compliance certifications applicable to the end application.
