Key Parameters

Substitute Part Grouping Explanation

Substitution of the Murata 76600/4C is determined by the following critical parameters:

Primary Substitution Criteria:

• Turns Ratio: 1:1 (exact match required)
• Mounting Type: Through Hole (physical compatibility)
• Physical Dimensions: 0.500" L x 0.350" W x 0.250" H maximum (PCB layout constraint)
• Operating Temperature Range: 0°C ~ 70°C (minimum requirement)
• Regulatory Compliance: REACH Unaffected, ECCN EAR99

Secondary Compatibility Factors:

• Inductance tolerance and ET (Volt-Time) product characteristics
• Transformer classification and application suitability

The Pulse Electronics PE-68629NL meets the primary substitution criteria through identical physical dimensions, matching turns ratio, compatible operating temperature range, and equivalent regulatory status.

Parameter Comparison

Engineering Selection Recommendations

The Pulse Electronics PE-68629NL serves as the manufacturer-recommended substitute for the obsolete Murata 76600/4C. Both components share identical physical dimensions and mounting characteristics, ensuring direct PCB compatibility without layout modifications. The PE-68629NL maintains the required 1:1 turns ratio and operates within the specified 0°C to 70°C temperature range.

The PE-68629NL is classified as an active product with current manufacturing support, providing supply chain continuity. Both components maintain equivalent regulatory status under REACH and ECCN classifications. The PE-68629NL carries RoHS3 compliance certification and specifies Moisture Sensitivity Level 1 (Unlimited), indicating superior environmental handling characteristics compared to the obsolete predecessor.

The inductance differential (50µH versus 40µH) and ET product specification variance require circuit-level evaluation to confirm functional equivalence within the target application.

Frequently Asked Questions (FAQ)

Q: Can the Pulse Electronics PE-68629NL be used as a direct replacement for the Murata 76600/4C?

A: Physical and electrical compatibility is established through matching dimensions, turns ratio, mounting type, and operating temperature range. The inductance difference (50µH to 40µH) must be evaluated against circuit requirements to confirm functional suitability.

Q: Are there any packaging differences between these components?

A: The Murata 76600/4C is supplied in standard packaging, while the Pulse Electronics PE-68629NL is packaged in Tube format. Both components maintain identical through-hole lead configurations and physical footprints suitable for PCB assembly.

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

A: The Murata 76600/4C is classified as obsolete, indicating discontinued manufacturing and limited availability. The Pulse Electronics PE-68629NL maintains active product status with ongoing manufacturing support and established supply chain availability.

Q: How do the regulatory certifications compare?

A: Both components share identical REACH Unaffected and EAR99 ECCN classifications. The PE-68629NL additionally specifies RoHS3 compliance, meeting current environmental regulatory requirements.

Q: What does the Moisture Sensitivity Level (MSL) specification indicate?

A: The Murata component lists MSL as Not Applicable, while the PE-68629NL specifies MSL 1 (Unlimited). MSL 1 indicates the component can be stored indefinitely without moisture control measures, providing superior handling flexibility during inventory management and assembly operations.
