EPSON MA-506 4.0000M-B3:ROHS Equivalent & Substitute Parts

Part Overview

The EPSON MA-506 4.0000M-B3:ROHS is a 4 MHz fundamental mode crystal oscillator designed for surface mount applications. This part operates at 4.0000 MHz with ±50ppm frequency stability and 16pF load capacitance. The product is currently obsolete, making identification of compatible substitute components essential for legacy system maintenance, repair, and redesign applications. Equivalent parts must maintain the same frequency, load capacitance, ESR characteristics, and operating temperature range to ensure direct functional replacement without circuit modification.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EPSON MA-506 4.0000M-B3:ROHS is determined by the following critical electrical parameters:

• Frequency Match: 4.0000 MHz (exact)
• Load Capacitance: 16pF (exact)
• ESR: 150 Ohms (exact)
• Operating Mode: Fundamental (exact)
• Operating Temperature Range: -20°C to 70°C minimum (equal or wider range acceptable)
• RoHS Compliance: ROHS3 Compliant (required for regulatory equivalence)
• Moisture Sensitivity: MSL 1 (acceptable)

The Diodes Incorporated GC0400058 meets all critical electrical substitution criteria. While the package form differs (HC-49/US versus 4-SOJ), both are surface mount configurations. The substitute part demonstrates superior frequency stability (±30ppm versus ±50ppm), which represents an improvement in performance margin without introducing incompatibility.

Parameter Comparison

Engineering Selection Recommendations

The Diodes Incorporated GC0400058 is a direct electrical equivalent for the obsolete EPSON MA-506 4.0000M-B3:ROHS. All critical electrical parameters—frequency, load capacitance, ESR, and operating temperature range—are identical. Both components maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and environmental compatibility.

The primary consideration for implementation is the package form factor change from 4-SOJ to HC-49/US. This difference requires PCB layout evaluation to confirm mechanical fit and clearance compatibility. The substitute part is currently in active production status with confirmed inventory availability (2708 pcs), providing supply chain continuity for legacy system support and new production runs.

Frequently Asked Questions (FAQ)

Q: Can the Diodes GC0400058 be used as a direct replacement without circuit modification?

A: The GC0400058 is electrically equivalent and requires no circuit modification. However, the package form factor differs (HC-49/US versus 4-SOJ), necessitating PCB layout verification for mechanical compatibility and mounting clearance.

Q: Why does the substitute part have tighter frequency stability (±30ppm vs ±50ppm)?

A: The GC0400058 demonstrates superior frequency stability performance. This represents an improvement in oscillator accuracy and does not create incompatibility with circuits designed for the original ±50ppm specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the EPSON MA-506 4.0000M-B3:ROHS and Diodes GC0400058 are ROHS3 compliant and suitable for applications requiring lead-free component certification.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both parts share this rating, eliminating moisture management as a substitution constraint.

Q: Is the HC-49/US package suitable for automated assembly?

A: HC-49/US is a surface mount package compatible with standard pick-and-place equipment. PCB footprint design must accommodate the specific dimensions (11.70mm L x 4.80mm W x 4.20mm H max) to ensure proper placement and solder joint formation.

Q: What inventory status should be considered for production planning?

A: The EPSON MA-506 is obsolete with no ongoing production. The Diodes GC0400058 is in active production status with 2708 pcs currently available, providing reliable supply for immediate and future requirements.
