Substitute Part Grouping Explanation

Substitution for the CCPD-034-50-311.040 is determined by strict alignment of the following critical parameters:

• Frequency: 311.04 MHz (exact match required)
• Output Type: LVPECL (signal format compatibility)
• Supply Voltage: 3.3V (power supply compatibility)
• Function: Enable/Disable (operational feature match)
• Package / Case: 6-SMD, No Lead (PCB footprint compatibility)
• Operating Temperature Range: 0°C ~ 70°C (thermal envelope compatibility)

The PM113-311.04M from Connor Winfield meets all substitution criteria. While it demonstrates improved frequency stability (±25ppm versus ±50ppm) and slightly lower maximum supply current (95mA versus 88mA), these represent performance enhancements rather than incompatibilities. The substitute maintains identical mechanical dimensions, electrical interface, and functional characteristics required for direct replacement.

Engineering Selection Recommendations

The PM113-311.04M is the qualified substitute for the obsolete CCPD-034-50-311.040. Selection between these parts should be based on the following factors:

For New Designs: The PM113-311.04M is the appropriate choice. It carries an Active product status, ensuring long-term availability and supply chain stability. The part is RoHS3 compliant, meeting current regulatory requirements for new product development.

For Legacy System Support: The PM113-311.04M provides direct functional replacement for existing CCPD-034-50-311.040 implementations. The improved frequency stability (±25ppm) and reduced seated height (1.75mm versus 1.80mm) present no compatibility issues and may enhance system performance.

Compliance Considerations: Both parts maintain identical REACH and ECCN classifications, ensuring regulatory equivalence. The Connor Winfield substitute's RoHS3 compliance status aligns with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the PM113-311.04M directly replace the CCPD-034-50-311.040 on existing PCBs?

A: Yes. Both parts share identical package specifications (6-SMD, No Lead), mechanical dimensions (7.00mm x 5.00mm), and electrical interfaces (3.3V LVPECL with enable/disable). The 0.02mm difference in seated height (1.75mm versus 1.80mm) is within standard PCB assembly tolerances and presents no compatibility concerns.

Q: What are the key differences between these oscillators?

A: The primary differences are frequency stability and supply current. The PM113-311.04M provides ±25ppm stability compared to the CCPD-034-50-311.040's ±50ppm, and draws up to 95mA versus 88mA. Both operate identically across the 0°C to 70°C temperature range and maintain the same 311.04 MHz output frequency.

Q: Why is the CCPD-034-50-311.040 listed as obsolete?

A: Crystek Corporation has discontinued this part number. The PM113-311.04M from Connor Winfield provides equivalent functionality with enhanced specifications and active product status, making it the recommended alternative for both new designs and legacy system support.

Q: Are there any supply chain advantages to using the PM113-311.04M?

A: Yes. The PM113-311.04M carries Active product status with 1001 pieces in stock, compared to the obsolete CCPD-034-50-311.040. This ensures reliable availability for production requirements and design flexibility.

Q: Do both parts require identical PCB layout considerations?

A: Yes. Both oscillators use the same 6-SMD, no-lead package and occupy identical footprint space (7.00mm x 5.00mm). No PCB redesign is necessary for substitution. Existing assembly processes and handling procedures remain unchanged.
