7V-19.200MAHV-T Equivalent & Substitute Parts

Part Overview

The 7V-19.200MAHV-T is a 19.2 MHz fundamental mode crystal oscillator manufactured by TXC CORPORATION. This surface mount device is designed for applications requiring precise frequency reference with tight stability specifications. The part is currently in active production status with 1116 pieces available in new original inventory.

Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across frequency, load capacitance, ESR, package dimensions, and operating temperature range. Alternative sources may be required due to supply chain considerations, lead time optimization, or inventory availability.

Substitute Part Grouping Explanation

Substitute parts for the 7V-19.200MAHV-T are identified based on strict equivalence of the following parameters:

Critical Electrical Parameters:

Frequency: 19.2 MHz (exact match required)
Frequency Stability: ±30ppm (exact match required)
Load Capacitance: 8pF (exact match required)
ESR: 60 Ohms (exact match required)
Operating Mode: Fundamental (exact match required)

Critical Mechanical Parameters:

Package Type: 4-SMD, No Lead (exact match required)
Dimensions: 3.20mm x 2.50mm (exact match required)
Mounting Type: Surface Mount (exact match required)

Environmental Parameters:

Operating Temperature Range: -40°C ~ 85°C (exact match required)

Compliance Parameters:

Frequently Asked Questions (FAQ)

Q: Can the 7M-19.200MAHV-T replace the 7V-19.200MAHV-T in existing designs?

A: Yes. Both parts share identical frequency (19.2 MHz), frequency stability (±30ppm), load capacitance (8pF), ESR (60 Ohms), operating temperature range (-40°C ~ 85°C), and package dimensions (3.20mm x 2.50mm 4-SMD). The 7M variant has a lower maximum seated height (0.80mm), which is compatible with standard PCB assembly specifications.

Q: What are the critical parameters that must match for substitution?

A: Frequency, frequency stability, load capacitance, ESR, operating mode, package type, dimensions, and operating temperature range must be identical. These parameters directly affect circuit performance and PCB layout compatibility.

Q: Does the height difference between 0.90mm and 0.80mm affect assembly?

A: No. The 7M-19.200MAHV-T's lower profile (0.80mm) is within standard SMD assembly tolerances and provides additional clearance. This is a compatible variation that does not require design changes.

Q: Are both parts RoHS compliant?

A: Yes. Both the 7V-19.200MAHV-T and 7M-19.200MAHV-T are RoHS compliant and suitable for applications requiring environmental compliance.

Q: What is the difference in packaging between the two parts?

A: The 7V-19.200MAHV-T packaging format is not specified in available data. The 7M-19.200MAHV-T is supplied in Tape & Reel (TR) format, which is standard for automated surface mount assembly processes.

Q: Can these parts be used interchangeably in production?

A: Yes, provided that PCB assembly equipment and reflow profiles are qualified for both part sources. The identical electrical and mechanical specifications ensure functional equivalence.
