XM-1-016.0M Equivalent & Substitute Parts

Part Overview

The XM-1-016.0M is a 16 MHz fundamental mode crystal oscillator manufactured by Connor Winfield, designed for surface mount applications requiring precise frequency control. This Active product is specified for 16pF load capacitance with ±50ppm frequency stability across the -10°C to 60°C operating temperature range. The compact 4-SMD, No Lead package (7.50mm x 5.00mm) with 1.30mm maximum seated height provides integration into space-constrained circuit designs. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the XM-1-016.0M is determined by the following critical parameters:

Primary Matching Criteria:

• Frequency: 16 MHz (exact match required)
• Frequency Stability: ±50ppm (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -10°C to 60°C (exact match required)
• Package / Case: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Secondary Compatibility Parameters:

• Load Capacitance: 16pF (primary specification; minor variations acceptable within circuit design tolerance)
• ESR: 40 Ohms (primary specification; minor variations acceptable within circuit design tolerance)
• RoHS Status: ROHS3 Compliant (regulatory requirement match)

The LFXTAL030819 from IQD Frequency Products meets all primary matching criteria. Secondary parameter variations (18pF load capacitance vs. 16pF; 50 Ohms ESR vs. 40 Ohms) represent minor deviations that remain within acceptable substitution tolerance for equivalent crystal oscillator applications.

Parameter Comparison

Engineering Selection Recommendations

Both the XM-1-016.0M and LFXTAL030819 are Active products with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component procurement.

The XM-1-016.0M is the primary specification with 16pF load capacitance and 40 Ohms ESR. The LFXTAL030819 serves as an equivalent substitute with matching frequency, stability, operating mode, temperature range, and package type. The LFXTAL030819 features a smaller footprint (5.00mm x 3.20mm vs. 7.50mm x 5.00mm) and lower maximum seated height (1.00mm vs. 1.30mm), providing potential space optimization benefits in PCB layout. The load capacitance increase from 16pF to 18pF and ESR increase from 40 Ohms to 50 Ohms represent minor parameter variations that remain within acceptable substitution tolerance for equivalent crystal oscillator circuit applications.

Selection between these parts should be based on PCB layout constraints, inventory availability, and circuit design validation for the specific load capacitance and ESR requirements.

Frequently Asked Questions (FAQ)

Q: Can the LFXTAL030819 be used as a direct replacement for the XM-1-016.0M?

A: Yes. Both parts share identical frequency (16 MHz), frequency stability (±50ppm), operating mode (Fundamental), operating temperature range (-10°C to 60°C), mounting type (Surface Mount), and package type (4-SMD, No Lead). The load capacitance and ESR variations (18pF vs. 16pF; 50 Ohms vs. 40 Ohms) are minor parameter differences that remain within acceptable substitution tolerance for equivalent crystal oscillator applications.

Q: What are the physical differences between these parts?

A: The LFXTAL030819 has a smaller footprint (5.00mm x 3.20mm) compared to the XM-1-016.0M (7.50mm x 5.00mm). The LFXTAL030819 also has a lower maximum seated height of 1.00mm versus 1.30mm for the XM-1-016.0M. These dimensional differences may provide PCB layout advantages in space-constrained applications.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the XM-1-016.0M and LFXTAL030819 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory standards for electronic component procurement.

Q: What is the significance of the load capacitance difference (16pF vs. 18pF)?

A: Load capacitance is a specification parameter that affects crystal oscillator circuit design and frequency tuning. The 2pF difference between the XM-1-016.0M (16pF) and LFXTAL030819 (18pF) represents a minor variation. Circuit design validation is necessary to confirm compatibility with the specific application's load capacitance requirements.

Q: What is the significance of the ESR difference (40 Ohms vs. 50 Ohms)?

A: Equivalent Series Resistance (ESR) affects crystal oscillator circuit performance and power consumption. The 10 Ohms difference between the XM-1-016.0M (40 Ohms) and LFXTAL030819 (50 Ohms) represents a minor variation. Circuit design validation is necessary to confirm compatibility with the specific application's ESR requirements.

Q: Are there packaging differences between these parts?

A: The XM-1-016.0M is supplied in Cut Tape (CT) packaging, while the LFXTAL030819 is supplied in Tape & Reel (TR) packaging. Both use the same 4-SMD, No Lead package type. Packaging format selection depends on procurement volume and assembly process requirements.
