Equivalent & Substitute Parts for Murata 1468422C

Part Overview

The Murata 1468422C is a 680 µH unshielded wirewound inductor rated for 2.2 A continuous current with a maximum DC resistance of 226mOhm. This through-hole radial component operates across the -40°C to 85°C temperature range and is classified as Active product status with full ROHS3 compliance. Substitute parts are identified to provide alternative sourcing options when the primary component becomes unavailable or when design requirements necessitate different electrical or mechanical characteristics within the allowed parameter range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Murata 1468422C is determined by the following critical parameters:

• Inductance Value: Must be 680 µH with ±10% tolerance
• Current Rating: Substitute must support minimum 2.2 A; higher ratings are acceptable
• DC Resistance: Must not exceed 226mOhm maximum
• Mounting Configuration: Through-hole radial vertical cylinder format required
• Shielding: Unshielded construction
• Compliance: ROHS3 and REACH status must match or exceed the original specification

The Bourns 1130-681K-RC meets these substitution criteria with equivalent inductance, superior current rating (2.8 A vs. 2.2 A), and compatible DC resistance (256mOhm vs. 226mOhm maximum). Both components share identical mounting type, package configuration, and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

Both the Murata 1468422C and Bourns 1130-681K-RC are Active status components with full ROHS3 and REACH compliance. The Bourns substitute provides enhanced performance margins with a higher current rating (2.8 A versus 2.2 A) and an extended operating temperature range (-55°C to 105°C versus -40°C to 85°C). The DC resistance differential of 30mOhm (256mOhm versus 226mOhm) remains within acceptable engineering tolerances for most through-hole inductor applications. Both components maintain identical inductance values, tolerance specifications, and mounting configurations, ensuring direct functional equivalence in circuit design.

Frequently Asked Questions (FAQ)

Q: Can the Bourns 1130-681K-RC be used as a direct replacement for the Murata 1468422C?

A: Yes. Both components share identical inductance (680 µH ±10%), equivalent mounting type (through-hole radial vertical cylinder), and matching regulatory compliance. The Bourns part provides higher current capacity (2.8 A versus 2.2 A) and wider temperature range, making it functionally compatible for the specified application.

Q: What is the significance of the DC resistance difference between these parts?

A: The Murata component specifies 226mOhm maximum DC resistance, while the Bourns substitute specifies 256mOhm maximum. This 30mOhm difference represents approximately 13% variance and remains within typical engineering tolerance for wirewound inductor applications. Circuit designers must verify that this resistance increase does not exceed thermal or efficiency requirements for their specific application.

Q: Are there physical dimension differences between these inductors?

A: Yes. The Murata 1468422C measures 0.961" diameter (24.40mm) with 0.787" seated height (20.00mm). The Bourns 1130-681K-RC measures 1.100" diameter (27.94mm) with 0.840" seated height (21.34mm). PCB layout and enclosure clearance must accommodate the larger Bourns component dimensions.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the Murata 1468422C and Bourns 1130-681K-RC are ROHS3 compliant and REACH unaffected, meeting identical environmental and regulatory standards.

Q: What core material differences exist between these inductors?

A: The Murata 1468422C uses unshielded wirewound construction with core material not specified in the datasheet. The Bourns 1130-681K-RC uses a ferrite drum core with unshielded wirewound construction. Both maintain unshielded configuration and equivalent inductance performance at the specified test frequency of 1 kHz.
