7Q-19.200MBG-T TCXO Oscillator Equivalent & Substitute Parts

Part Overview

The 7Q-19.200MBG-T is a 19.2 MHz Temperature Compensated Crystal Oscillator (TCXO) manufactured by TXC CORPORATION. This surface mount oscillator delivers a clipped sine wave output at 3.3V supply voltage with ±500ppb frequency stability across the -30°C to 85°C operating temperature range. The part is classified as obsolete, necessitating identification of active equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain identical electrical performance and mechanical compatibility within the 4-SMD, No Lead package format.

Substitute Part Grouping Explanation

Substitution of the 7Q-19.200MBG-T is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Criteria:

• Frequency: 19.2 MHz (exact match required)
• Output Configuration: Clipped Sine Wave (exact match required)
• Supply Voltage: 3.3V (exact match required)
• Frequency Stability: ±500ppb (exact match required)
• Operating Temperature Range: -30°C to 85°C (exact match required)
• Maximum Supply Current: 2mA (exact match required)

Mechanical Equivalence Criteria:

• Package Type: 4-SMD, No Lead (exact match required)
• Physical Dimensions: 0.126" L x 0.098" W / 3.20mm x 2.50mm (exact match required)
• Mounting Type: Surface Mount (exact match required)

Compliance Criteria:

• RoHS Status: RoHS Compliant or higher (ROHS3 acceptable)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The Connor Winfield D32G series parts (D32G-019.2M and D32G-019.2M-T) satisfy all electrical and mechanical equivalence requirements. Both parts are active products with enhanced RoHS3 compliance status, providing direct functional replacement capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: D32G-019.2M-T

The D32G-019.2M-T is the recommended substitute for the obsolete 7Q-19.200MBG-T. This part maintains complete electrical equivalence across all specified parameters and is supplied in Tape & Reel packaging format, which is standard for production environments. The part carries active product status with ROHS3 compliance, exceeding the original RoHS Compliant specification. Current inventory of 760 pieces supports immediate procurement requirements.

Secondary Substitute: D32G-019.2M

The D32G-019.2M provides identical electrical and mechanical specifications to the D32G-019.2M-T variant. This part is also active and ROHS3 compliant. The primary distinction is packaging format (Tape & Reel). Selection between D32G-019.2M and D32G-019.2M-T depends on procurement and assembly process requirements. Inventory availability is 1297 pieces.

Compliance Status:

Both Connor Winfield substitutes exceed the original compliance requirements. The upgrade from RoHS Compliant to ROHS3 Compliant status ensures compatibility with current and future regulatory frameworks. Both parts maintain REACH Unaffected and EAR99 ECCN classifications consistent with the original part.

Physical Compatibility Note:

The substitute parts exhibit a maximum seated height of 0.047" (1.20mm) compared to the original 0.043" (1.10mm). This 0.004" (0.10mm) height differential must be evaluated within specific PCB layout and assembly constraints. In standard surface mount applications with typical component clearances, this variance does not present compatibility issues.

Frequently Asked Questions (FAQ)

Q: Can D32G-019.2M and D32G-019.2M-T be used interchangeably with the 7Q-19.200MBG-T?

A: Yes. Both Connor Winfield parts provide complete electrical and mechanical equivalence. The D32G-019.2M-T is supplied in Tape & Reel format, while D32G-019.2M is supplied in bulk packaging. Selection depends on procurement and assembly process requirements.

Q: What is the significance of the height difference between the original part and substitutes?

A: The original 7Q-19.200MBG-T has a maximum seated height of 0.043" (1.10mm), while both D32G substitutes measure 0.047" (1.20mm) maximum. This 0.004" (0.10mm) difference is within standard PCB design tolerances for surface mount components and does not affect functionality in typical applications.

Q: Are the Connor Winfield substitutes RoHS compliant?

A: Yes. Both D32G-019.2M and D32G-019.2M-T carry ROHS3 Compliant status, which exceeds the original RoHS Compliant specification of the 7Q-19.200MBG-T.

Q: What packaging formats are available for the substitute parts?

A: Both Connor Winfield substitutes are supplied in Tape & Reel (TR) format. The original 7Q-19.200MBG-T was supplied in bulk packaging.

Q: Do the substitute parts maintain the same frequency stability specification?

A: Yes. Both D32G-019.2M and D32G-019.2M-T maintain the ±500ppb frequency stability specification across the -30°C to 85°C operating temperature range.

Q: Are there any differences in supply current requirements?

A: No. All three parts (original and both substitutes) specify a maximum supply current of 2mA at 3.3V supply voltage.

Q: What is the current inventory status for substitute parts?

A: D32G-019.2M-T: 760 pieces in stock. D32G-019.2M: 1297 pieces in stock. Both are available for immediate procurement.
