XL-1C-018.432M Equivalent & Substitute Parts

Part Overview

The XL-1C-018.432M is an 18.432 MHz surface mount crystal oscillator manufactured by Connor Winfield. This fundamental mode crystal operates at ±50ppm frequency stability with a 16pF load capacitance and 40 Ohms equivalent series resistance. The component is supplied in 4-SMD, No Lead packaging with Tape & Reel (TR) configuration. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), making it suitable for industrial and commercial applications requiring stable frequency reference.

Substitute parts are identified based on identical electrical performance specifications and compatible mechanical form factors, ensuring direct functional replacement in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the XL-1C-018.432M is determined by strict equivalence across the following critical parameters:

• Frequency: 18.432 MHz (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Load Capacitance: 16pF (exact match required)
• ESR: 40 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Operating Temperature Range: -10°C to 60°C (minimum required)
• RoHS Compliance: ROHS3 (minimum required)

The XM-1-018.432M qualifies as a direct substitute based on identical electrical specifications and compatible mechanical packaging. Packaging configuration differences (Tape & Reel versus Cut Tape) do not affect functional equivalence and represent supply chain variations only.

Parameter Comparison

Engineering Selection Recommendations

Both the XL-1C-018.432M and XM-1-018.432M are Active status products from Connor Winfield with identical electrical specifications. Selection between these parts is based on supply chain requirements and packaging format:

• XL-1C-018.432M: Select when Tape & Reel packaging is required for automated assembly processes
• XM-1-018.432M: Select when Cut Tape packaging is acceptable or preferred for lower-volume applications

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard PCB assembly and storage conditions. Physical dimension variations are minor and do not impact PCB layout or circuit performance.

Frequently Asked Questions (FAQ)

Q: Can XM-1-018.432M replace XL-1C-018.432M in production?

A: Yes. Both parts are electrically identical with matching frequency, stability, load capacitance, and ESR specifications. The difference is packaging configuration (Cut Tape versus Tape & Reel), which does not affect functional performance.

Q: Are there physical compatibility concerns between these parts?

A: Physical dimensions differ slightly (XL-1C: 7.62mm x 5.08mm; XM-1: 7.50mm x 5.00mm). Both fit the same 4-SMD, No Lead footprint. Height variation (1.77mm versus 1.30mm) does not create clearance issues in standard PCB designs.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Compliance certifications are identical.

Q: What determines substitution eligibility for 18.432 MHz crystals?

A: Exact matching of frequency (18.432 MHz), frequency stability (±50ppm), load capacitance (16pF), ESR (40 Ohms), operating mode (Fundamental), and package type (4-SMD, No Lead) is required. Operating temperature range and RoHS compliance must meet or exceed application requirements.

Q: Can parts with different packaging formats be mixed in the same design?

A: Yes. Tape & Reel and Cut Tape configurations represent supply chain variations only. Both formats contain identical components and perform identically in circuit operation.
