DOC050F-020.0M Equivalent & Substitute Parts

Part Overview

The DOC050F-020.0M is a 20 MHz OCXO (Oven Controlled Crystal Oscillator) manufactured by Connor Winfield, designed for applications requiring stable frequency output with LVCMOS logic levels at 3.3V supply voltage. This part is classified as Obsolete, necessitating identification of equivalent alternatives for ongoing production and maintenance applications. Substitute parts maintain identical electrical specifications and mechanical compatibility while offering improved availability or active product status.

Substitute Part Grouping Explanation

Substitution eligibility for the DOC050F-020.0M is determined by strict equivalence across the following critical parameters:

• Frequency: 20.0000 MHz (exact match required)
• Output Logic: LVCMOS (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Frequency Stability: ±50ppb (exact match required)
• Operating Temperature: 0°C to 70°C (exact match required)
• Package: 6-SMD, No Lead (exact match required)
• Physical Footprint: 14.10mm × 9.10mm (exact match required)
• Compliance: ROHS3 Compliant, MSL 1 (exact match required)

The identified substitutes DOCAT050F-020.0M and DOXSC050F-020.0M meet all electrical and mechanical equivalence criteria. Differences in packaging format (Cut Tape vs. Tape & Reel) and product status do not affect functional interchangeability in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, DOXSC050F-020.0M is the preferred selection due to Active product status and manufacturer support. This part maintains full electrical and mechanical equivalence to DOC050F-020.0M while ensuring long-term availability and supply chain continuity.

DOCAT050F-020.0M serves as a secondary alternative where Cut Tape packaging is operationally acceptable. Although discontinued at DiGi Electronics, this part remains electrically equivalent and suitable for applications where inventory availability permits.

All three parts satisfy ROHS3 compliance and REACH requirements, with identical MSL ratings and environmental specifications. Height variation between DOC050F-020.0M (7.80mm) and substitute parts (8.51mm) must be evaluated for applications with strict PCB clearance constraints, though this difference remains within typical surface-mount assembly tolerances.

Frequently Asked Questions (FAQ)

Q: Can DOXSC050F-020.0M directly replace DOC050F-020.0M in existing assemblies?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 20 MHz frequency, LVCMOS output, 3.3V supply, ±50ppb stability, and 6-SMD package footprint. The 0.71mm height difference (7.80mm vs. 8.51mm) is within standard PCB assembly tolerances and does not affect circuit functionality.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Packaging format affects supply chain logistics and handling. Cut Tape (DOCAT050F-020.0M) is supplied in smaller quantities on individual tape segments, while Tape & Reel (DOXSC050F-020.0M) is supplied in continuous reels for high-volume automated assembly. Both formats contain identical components with no functional difference.

Q: Why is DOC050F-020.0M classified as Obsolete?

A: Obsolete status indicates the manufacturer has discontinued active production and support. DOXSC050F-020.0M, maintained as an Active product, provides equivalent functionality with ongoing manufacturer backing and supply assurance.

Q: Are all three parts ROHS3 compliant?

A: Yes. DOC050F-020.0M, DOCAT050F-020.0M, and DOXSC050F-020.0M are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating, meeting environmental and regulatory requirements for industrial and commercial applications.

Q: Can these parts be used interchangeably in production?

A: Yes, provided PCB layout accommodates the maximum seated height of 8.51mm for DOCAT050F-020.0M and DOXSC050F-020.0M. No circuit redesign is required for functional substitution.
