Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the L08P100D15 is determined by strict alignment with the following core electrical and mechanical parameters:

Primary Substitution Criteria:

• Current sensing capacity: 100A
• Sensor technology: Hall Effect, Open Loop
• Measurement capability: AC/DC Bidirectional
• Channel configuration: Single channel
• Output format: Ratiometric voltage
• Mounting method: Through Hole
• Package classification: Module

Secondary Compatibility Parameters:

• Frequency response: Minimum DC ~ 50kHz (L08P100D15 operates to 100kHz)
• Linearity specification: ±1% or better
• Supply voltage compatibility: ±12V to ±15V range
• Operating temperature overlap: Minimum -10°C to 80°C
• RoHS compliance status

Parts meeting all primary criteria and maintaining secondary parameter compatibility are classified as direct substitutes. Variations in response time, supply current consumption, or extended temperature ranges do not disqualify substitution when primary electrical and mechanical parameters align.

Engineering Selection Recommendations

L08P100D15IPV (Manufacturer Recommended Substitute):

The L08P100D15IPV is the primary recommended substitute, manufactured by Tamura as the active-status successor to the obsolete L08P100D15. This part maintains identical electrical specifications for current sensing (100A), sensor technology (Hall Effect, Open Loop), measurement capability (AC/DC Bidirectional), and output format (Ratiometric Voltage). The L08P100D15IPV carries ROHS3 compliance certification, representing current regulatory alignment. Packaging is specified as Tray format. Response time is improved to 5µs compared to the original 10µs specification. Operating temperature range extends to -20°C, providing broader environmental coverage. Supply current consumption increases to 20mA maximum. This part is currently in active production with confirmed inventory availability.

HTB 100-P (Alternative Substitute):

The HTB 100-P, manufactured by LEM USA Inc., qualifies as a functional substitute based on alignment with all primary substitution criteria: 100A current sensing, Hall Effect open-loop technology, AC/DC bidirectional measurement, single-channel configuration, and ratiometric voltage output. This part is active-status with confirmed inventory. The HTB 100-P demonstrates superior response time performance at 3µs and extended operating temperature range (-40°C to 80°C). Frequency response specification is DC to 50kHz, which is lower than the original L08P100D15 (DC to 100kHz) but remains within acceptable parameters for most industrial applications. Supply voltage compatibility spans ±12V to ±15V. RoHS compliance is confirmed. The HTB 100-P features single pass-through module construction.

Selection Basis:

Both substitute parts satisfy the mandatory electrical and mechanical compatibility requirements. Selection between L08P100D15IPV and HTB 100-P should be based on application-specific frequency requirements, temperature operating envelope, and supply voltage availability within the design. The L08P100D15IPV maintains manufacturer continuity and identical frequency response. The HTB 100-P offers enhanced response time and temperature range coverage.

Frequently Asked Questions (FAQ)

Q: Can the L08P100D15IPV be used as a direct replacement for the L08P100D15?

A: Yes. The L08P100D15IPV maintains identical electrical specifications for current sensing range (100A), sensor technology (Hall Effect, Open Loop), measurement type (AC/DC Bidirectional), channel count (1), output format (Ratiometric Voltage), frequency response (DC ~ 100kHz), linearity (±1%), and supply voltage (±15V). Both components use through-hole mounting and module packaging. The L08P100D15IPV is the active-status Tamura equivalent.

Q: What are the key differences between L08P100D15IPV and HTB 100-P?

A: Both parts meet primary substitution criteria. Key differences include: manufacturer (Tamura vs. LEM USA Inc.), frequency range (DC ~ 100kHz vs. DC ~ 50kHz), response time (5µs vs. 3µs), operating temperature range (-20°C ~ 80°C vs. -40°C ~ 80°C), and supply current consumption (20mA vs. 15mA maximum). The HTB 100-P offers faster response and wider temperature coverage; the L08P100D15IPV maintains identical frequency response to the original part.

Q: Are there packaging differences between these substitutes?

A: The L08P100D15 original part uses standard module packaging. The L08P100D15IPV substitute specifies Tray packaging. The HTB 100-P is specified as Module with Single Pass Through construction. All three maintain through-hole mounting type. Packaging format selection should align with assembly process requirements and inventory management systems.

Q: Can the HTB 100-P be used in applications requiring DC to 100kHz frequency response?

A: The HTB 100-P frequency specification is DC to 50kHz. Applications requiring response to 100kHz should use the L08P100D15IPV, which maintains the original L08P100D15 frequency specification of DC to 100kHz.

Q: What is the temperature operating range difference impact?

A: The L08P100D15 operates from -10°C to 80°C. The L08P100D15IPV extends the lower limit to -20°C. The HTB 100-P provides the widest range at -40°C to 80°C. Selection should match the application's thermal environment. Extended temperature range does not affect substitution eligibility but may provide operational advantages in temperature-extreme applications.

Q: Are both substitutes RoHS compliant?

A: Yes. The L08P100D15IPV carries ROHS3 compliance certification. The HTB 100-P is RoHS compliant. Both meet current regulatory requirements for restricted substance elimination.

Q: What is the significance of response time differences (10µs vs. 5µs vs. 3µs)?

A: Response time indicates the sensor's speed in detecting current changes. The original L08P100D15 has 10µs response time. The L08P100D15IPV improves this to 5µs. The HTB 100-P provides the fastest response at 3µs. Faster response time enables detection of more rapid current transients. Application requirements determine whether improved response time is necessary or beneficial.

Q: Can supply voltage differences affect substitution?

A: The L08P100D15 and L08P100D15IPV both require ±15V supply. The HTB 100-P accepts ±12V to ±15V supply voltage range. If the application provides exactly ±15V, all three parts are compatible. If the application provides ±12V, only the HTB 100-P is suitable. Verify supply voltage availability before final part selection.
