FCR8.0M5 Equivalent & Substitute Parts

Part Overview

The FCR8.0M5 is an 8 MHz ceramic resonator manufactured by TDK Corporation, designed for through-hole applications with ±0.3% frequency stability across the -40°C to 85°C operating temperature range. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and production continuity. Ceramic resonators in this frequency and stability class are used in timing and clock generation circuits where precise frequency control is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the FCR8.0M5 is based on matching the following critical electrical and mechanical parameters:

• Frequency: 8 MHz (exact match required)
• Frequency Stability: ±0.3% (determines timing accuracy)
• Impedance: 30 Ohms (circuit matching requirement)
• Operating Temperature Range: -40°C to 85°C (environmental compatibility)
• Mounting Type: Through Hole (PCB assembly compatibility)
• Package / Case: Radial - 2 Lead, 5.00mm Pitch (footprint compatibility)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage requirements)

The HWZT-8.00MD from Abracon LLC meets all specified electrical parameters and maintains mechanical compatibility through identical lead pitch and mounting type. Minor dimensional variations in length and height do not affect functional performance or PCB placement when the pitch and mounting type remain constant.

Parameter Comparison

Engineering Selection Recommendations

The HWZT-8.00MD is a direct functional equivalent for the FCR8.0M5. Both components share identical electrical specifications and mechanical compatibility through matching lead pitch and through-hole mounting configuration. The primary distinction is product status: the FCR8.0M5 is obsolete, while the HWZT-8.00MD is active and currently in production.

The HWZT-8.00MD carries ROHS3 compliance certification, providing regulatory advantage for applications subject to RoHS requirements. The component is available in higher inventory quantities (1013 pcs vs. 843 pcs), supporting production continuity and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can the HWZT-8.00MD be used as a direct replacement for the FCR8.0M5?

A: Yes. Both components meet identical electrical specifications (8 MHz, ±0.3% stability, 30 Ohms impedance, -40°C to 85°C operating range) and share the same mechanical footprint (Radial - 2 Lead, 5.00mm Pitch through-hole package).

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. The FCR8.0M5 measures 0.374" L × 0.197" W × 0.256" H, while the HWZT-8.00MD measures 0.394" L × 0.197" W × 0.217" H. These differences do not affect PCB placement or circuit performance, as the critical parameter—lead pitch—remains constant at 5.00mm.

Q: What is the significance of the product status difference?

A: The FCR8.0M5 is classified as obsolete, indicating TDK has discontinued production. The HWZT-8.00MD is active and in current production, ensuring long-term availability and supply chain reliability.

Q: Does the HWZT-8.00MD meet RoHS requirements?

A: Yes. The HWZT-8.00MD is ROHS3 compliant, meeting current regulatory standards for restricted substances in electrical and electronic equipment.

Q: Are moisture sensitivity requirements the same?

A: Yes. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control measures are required during storage or handling.
