HR01100J Equivalent & Substitute Parts

Part Overview

The HR01100J is a 10 Ohm ±5% 1/16W axial through-hole resistor manufactured by KYOCERA AVX using thick film composition. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across a temperature range of -55°C to 125°C and is not RoHS compliant.

Key Parameters

Substitute Part Grouping Explanation

The CFR-12JB-52-10R from YAGEO qualifies as a functional substitute based on the following critical parameters:

Matching Parameters:

• Resistance value: 10 Ohms
• Tolerance: ±5%
• Package type: Axial through-hole
• Number of terminations: 2
• Operating temperature range: -55°C to 155°C (encompasses HR01100J range)

Allowable Differences:

• Power rating: 0.167W (1/6W) versus 0.063W (1/16W) — higher rating provides margin
• Composition: Carbon Film versus Thick Film — both acceptable for general-purpose applications
• Temperature coefficient: -500/+350ppm/°C versus ±250ppm/°C — within acceptable variance for 5% tolerance resistors
• RoHS status: ROHS3 Compliant versus non-compliant — substitute meets modern compliance requirements

Parameter Comparison

Engineering Selection Recommendations

The CFR-12JB-52-10R is the designated substitute for the obsolete HR01100J. Selection is based on:

• Electrical equivalence: Identical resistance and tolerance specifications ensure direct functional replacement in circuits designed for 10 Ohm ±5% resistors
• Power margin: The 0.167W rating of the CFR-12JB-52-10R exceeds the original 0.063W requirement, providing operational headroom
• Active product status: The YAGEO component is in active production, ensuring long-term availability and supply chain continuity
• Compliance upgrade: ROHS3 compliance of the substitute aligns with current regulatory requirements, whereas the original part does not meet modern standards
• Temperature range: The extended operating range (-55°C to 155°C) of the substitute encompasses the original specification

Frequently Asked Questions (FAQ)

Q: Can the CFR-12JB-52-10R be used as a direct replacement for HR01100J in existing designs?

A: Yes. Both components share identical resistance (10 Ohms) and tolerance (±5%) specifications. The axial package and two-termination configuration are identical, allowing direct PCB substitution without layout modifications.

Q: What is the significance of the different power ratings?

A: The CFR-12JB-52-10R is rated at 0.167W compared to the HR01100J at 0.063W. A higher power rating does not degrade performance in applications requiring lower power dissipation; it simply provides additional thermal margin. This is advantageous for reliability.

Q: How do the temperature coefficients differ, and does this matter?

A: The HR01100J has a symmetric coefficient of ±250ppm/°C, while the CFR-12JB-52-10R has an asymmetric coefficient of -500/+350ppm/°C. For circuits with ±5% tolerance resistors, this variance is within acceptable limits and does not affect general-purpose applications.

Q: Why is the substitute RoHS compliant when the original is not?

A: The HR01100J predates modern RoHS regulations and is classified as obsolete. The CFR-12JB-52-10R is a current-production component manufactured to ROHS3 standards, reflecting contemporary environmental and regulatory compliance requirements.

Q: Are there any physical dimension differences between these parts?

A: Yes. The HR01100J measures 0.036" square × 0.075" length, while the CFR-12JB-52-10R measures 0.075" diameter × 0.134" length. Both are axial packages suitable for through-hole PCB mounting. Verify PCB layout clearances if space constraints exist.
