7V-54.000MAHV-T Crystal Oscillator Equivalent & Substitute Parts

Part Overview

The 7V-54.000MAHV-T is a 54 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION. This surface mount device operates across the industrial temperature range of -40°C to 85°C with a frequency stability of ±30ppm and an 8pF load capacitance specification. The component is classified as Active product status with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Alternative equivalent parts are identified when the primary part becomes unavailable or when specific load capacitance requirements necessitate substitution within the same frequency and stability parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 7V-54.000MAHV-T is determined by strict alignment of the following parameters:

Critical Matching Parameters:

• Frequency: 54 MHz (exact match required)
• Frequency Stability: ±30ppm (exact match required)
• ESR: 60 Ohms (exact match required)
• Operating Mode: Fundamental (exact match required)
• Operating Temperature Range: -40°C to 85°C (exact match required)
• Package Type: 4-SMD, No Lead (exact match required)
• Mounting Type: Surface Mount (exact match required)

Allowable Variation Parameter:

• Load Capacitance: Substitutes with 10pF load capacitance are acceptable when circuit design accommodates the capacitive load difference. The 10pF specification represents a 2pF increase from the primary part specification.

The identified substitute ILCX19-FF5F10-54.000MHZ meets all critical parameters while operating with a 10pF load capacitance. This variation is permissible in applications where the oscillator circuit is designed to accept load capacitance values within this range.

Engineering Selection Recommendations

Primary Part Selection: The 7V-54.000MAHV-T remains the preferred component when available. This part carries Active product status, full RoHS compliance, and is currently in stock with 2860 units available. The 8pF load capacitance specification aligns with standard oscillator circuit designs for this frequency range.

Substitute Part Selection: The ILCX19-FF5F10-54.000MHZ from ILSI is an acceptable equivalent when the primary part is unavailable. This substitute maintains all critical electrical parameters including frequency, stability, ESR, and operating temperature range. The component carries ROHS3 compliance, which exceeds RoHS requirements, and is currently in stock with 3627 units available.

Load Capacitance Consideration: The 10pF load capacitance of the substitute part represents a 2pF increase from the primary specification. Component selection between these parts depends on circuit design specifications. Applications designed to operate with load capacitance values between 8pF and 10pF can accommodate either part without modification. Applications with strict 8pF load capacitance requirements must use the primary part.

Physical Dimensions: The ILCX19-FF5F10-54.000MHZ features a smaller footprint (2.00mm x 1.60mm versus 3.20mm x 2.50mm) and lower profile (0.55mm versus 0.90mm). PCB layout compatibility must be verified before substitution, as the smaller dimensions may require footprint adjustment.

Regulatory and Compliance: Both parts satisfy REACH and EAR99 export classification requirements. Both carry unlimited moisture sensitivity ratings (MSL 1), eliminating special handling requirements during storage and assembly.

Frequently Asked Questions (FAQ)

Q: Can the ILCX19-FF5F10-54.000MHZ directly replace the 7V-54.000MAHV-T without circuit modification?

A: Direct replacement is possible only if the circuit design accommodates load capacitance values of 10pF. The 2pF increase in load capacitance may affect oscillation frequency and startup characteristics in circuits with tight load capacitance specifications. Circuit verification is necessary when the primary design specification requires exactly 8pF load capacitance.

Q: What is the significance of the load capacitance difference between these parts?

A: Load capacitance determines the external capacitive loading that the oscillator circuit presents to the crystal. The 8pF specification of the primary part and the 10pF specification of the substitute represent different circuit design points. Oscillator circuits are typically designed for a specific load capacitance value. Substituting a part with different load capacitance may shift the oscillation frequency within the stability tolerance or affect startup behavior.

Q: Are the physical dimensions compatible for PCB substitution?

A: The substitute part is physically smaller (2.00mm x 1.60mm versus 3.20mm x 2.50mm) and has a lower profile (0.55mm versus 0.90mm). While both use 4-SMD, No Lead packages, the footprint dimensions differ. PCB layout must be verified to confirm that the smaller component footprint is compatible with existing solder pads and clearance requirements.

Q: Do both parts meet the same regulatory and compliance standards?

A: Both parts carry REACH Unaffected status and EAR99 export classification. The primary part is RoHS Compliant, while the substitute is ROHS3 Compliant. ROHS3 represents an updated compliance standard that exceeds RoHS requirements. Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings, eliminating special handling during storage and assembly.

Q: What is the difference between RoHS and ROHS3 compliance?

A: RoHS (Restriction of Hazardous Substances) and ROHS3 both restrict the use of hazardous materials in electronic components. ROHS3 represents a more recent version of the standard with updated requirements. Components meeting ROHS3 compliance also satisfy RoHS requirements. Both designations indicate compliance with hazardous substance restrictions.

Q: Can these parts be used interchangeably in all 54 MHz applications?

A: Interchangeability depends on circuit design specifications. Both parts operate at 54 MHz with ±30ppm stability and 60 Ohms ESR across the -40°C to 85°C temperature range. The primary difference is load capacitance (8pF versus 10pF). Applications designed for 8pF load capacitance require the primary part. Applications designed for 10pF load capacitance or with flexible load capacitance specifications can use the substitute.

Q: What inventory considerations apply to these parts?

A: The primary part (7V-54.000MAHV-T) has 2860 units in stock. The substitute part (ILCX19-FF5F10-54.000MHZ) has 3627 units in stock. Both parts carry Active product status, indicating ongoing manufacturer support and availability.
