Substitute Part Grouping Explanation

Substitution of the CVPD-914X-50-155.52 is determined by strict equivalence across the following critical parameters:

• Frequency: 155.52 MHz (exact match required)
• Type: VCXO (Voltage Controlled Crystal Oscillator)
• Output Standard: LVPECL (Low Voltage Positive Emitter Coupled Logic)
• Supply Voltage: 3.3V
• Function: Enable/Disable capability
• Absolute Pull Range (APR): ±50ppm
• Operating Temperature Range: -40°C ~ 85°C
• Maximum Supply Current: 88mA
• Package / Case: 6-SMD, No Lead
• Physical Dimensions: 0.559" L x 0.360" W (14.20mm x 9.14mm)
• Height - Seated (Max): 0.209" (5.30mm)
• Compliance: ROHS3 Compliant, REACH Unaffected

The CVPD-940X-155.520 meets all substitution criteria as a parametric equivalent from the same manufacturer, with identical electrical specifications and mechanical compatibility.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can the CVPD-940X-155.520 be used as a direct replacement for the CVPD-914X-50-155.52?

A: Yes. Both parts are parametric equivalents with identical frequency (155.52 MHz), output standard (LVPECL), supply voltage (3.3V), pull range (±50ppm), operating temperature range (-40°C ~ 85°C), and package specifications (6-SMD, No Lead). Electrical and mechanical compatibility is complete.

Q: What is the difference between these two part numbers?

A: The CVPD-914X-50-155.52 is Obsolete, while the CVPD-940X-155.520 is Active. Both are from the same manufacturer and share identical specifications. The series designation differs (CVPD-914 vs. CVPD-940), reflecting product line evolution. The substitute part offers continued manufacturing support and availability.

Q: Are there any packaging differences?

A: The main part is supplied in standard packaging, while the substitute (CVPD-940X-155.520) is available in Strip packaging. Both use the same 6-SMD, No Lead surface mount package with identical physical dimensions (0.559" L x 0.360" W, 14.20mm x 9.14mm) and height (0.209" / 5.30mm maximum).

Q: Do both parts meet current compliance standards?

A: Yes. Both the CVPD-914X-50-155.52 and CVPD-940X-155.520 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What is the Absolute Pull Range (APR) and why is it important for substitution?

A: The APR of ±50ppm defines the frequency tuning range of the VCXO. Both parts share this specification, ensuring equivalent frequency control characteristics in applications requiring voltage-controlled frequency adjustment.

Q: Can I use the CVPD-940X-155.520 in existing designs currently using the CVPD-914X-50-155.52?

A: Yes. The substitute part maintains full electrical and mechanical compatibility. No circuit modifications or PCB redesign is required for direct substitution.
