L1007C102MPWST Equivalent & Substitute Parts

Part Overview

The L1007C102MPWST is a 1 mH unshielded drum core wirewound inductor manufactured by KEMET in the L-PWS series. This surface mount component is rated for 15 mA continuous current with 24 Ohm DC resistance and operates across the temperature range of -40°C to 105°C. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and repair applications. Substitute parts must maintain identical electrical performance and mechanical compatibility within the 1007 (2518 Metric) package footprint.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the L1007C102MPWST is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Inductance value: 1 mH
• Inductance tolerance: ±20%
• Current rating: 15 mA minimum
• DC resistance: 24 Ohm
• Self-resonant frequency: 2.4 MHz
• Core material: Ferrite
• Shielding configuration: Unshielded

Mechanical Parameters:

• Package designation: 1007 (2518 Metric)
• Physical dimensions: 0.098" L × 0.071" W (2.50mm × 1.80mm)
• Maximum seated height: 0.079" (2.00mm)
• Mounting type: Surface Mount

Compliance Parameters:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts must satisfy all electrical and mechanical parameters without deviation. Packaging format (Tape & Reel versus bulk) does not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The LB2518T102M manufactured by Taiyo Yuden is a direct electrical and mechanical equivalent to the L1007C102MPWST. All critical inductance, current, resistance, and dimensional specifications are identical. Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

The primary distinction between these parts is the operating temperature range. The L1007C102MPWST operates from -40°C to 105°C, while the LB2518T102M operates from -25°C to 105°C. For applications requiring operation below -25°C, the L1007C102MPWST provides extended low-temperature performance. For applications operating within the -25°C to 105°C range, the LB2518T102M is fully suitable.

The L1007C102MPWST is classified as obsolete, while the LB2518T102M is classified as Not For New Designs. Both parts are available in current inventory. Selection between these parts should be based on specific application temperature requirements and long-term supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can the LB2518T102M replace the L1007C102MPWST in all applications?

A: The LB2518T102M is electrically and mechanically equivalent for applications operating within the -25°C to 105°C temperature range. Applications requiring operation below -25°C require the L1007C102MPWST due to its extended low-temperature rating of -40°C.

Q: Are the physical footprints identical?

A: Yes. Both components use the 1007 (2518 Metric) package with identical dimensions of 0.098" L × 0.071" W (2.50mm × 1.80mm) and maximum seated height of 0.079" (2.00mm). PCB layout and assembly processes require no modification.

Q: What is the difference between Tape & Reel and bulk packaging?

A: Packaging format affects supply chain logistics and handling but does not alter electrical performance or mechanical compatibility. The LB2518T102M is supplied in Tape & Reel format, which is standard for automated assembly processes.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the L1007C102MPWST and LB2518T102M are ROHS3 compliant and carry identical moisture sensitivity levels of MSL 1 (Unlimited).

Q: What is the significance of the ±20% inductance tolerance?

A: The ±20% tolerance indicates that the actual inductance value may vary between 0.8 mH and 1.2 mH. Both substitute parts carry identical tolerance specifications, ensuring equivalent performance variation across production batches.

Q: Are there any frequency-dependent differences between these parts?

A: Both components exhibit identical self-resonant frequency of 2.4 MHz and are tested at 252 kHz. No frequency-dependent performance differences exist between the parts.
