Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC14KB100R is determined by the following critical parameters:

• Resistance Value: Must be 100 Ohms
• Package Type: Must be Axial to maintain mechanical and electrical compatibility
• Tolerance: Acceptable range ±5% to ±10%
• Power Rating: Minimum 0.25W; higher ratings acceptable
• Operating Temperature Range: Must encompass or exceed -55°C to 125°C
• Compliance: RoHS3 compliance required

The ASRM12JB100R meets these substitution criteria while offering improved specifications in tolerance and power rating.

Parameter Comparison

Engineering Selection Recommendations

The ASRM12JB100R is the manufacturer-recommended substitute for the RC14KB100R. Both components maintain identical resistance values and axial package configurations. The substitute provides enhanced specifications: improved tolerance (±5% versus ±10%), increased power rating (0.5W versus 0.25W), and extended operating temperature range (-55°C to 155°C versus -55°C to 125°C). Both parts maintain ROHS3 compliance and are suitable for equivalent circuit applications. The transition from carbon composition to metal film composition in the substitute provides improved stability and reliability characteristics. The active product status of the ASRM12JB100R ensures continued availability and supply chain support.

Frequently Asked Questions (FAQ)

Q: Can the ASRM12JB100R directly replace the RC14KB100R in existing designs?

A: Yes. Both components share identical resistance values, tolerance compatibility, and axial package configurations. The substitute's higher power rating and improved tolerance provide equivalent or superior performance in the same mechanical footprint.

Q: What is the primary reason for substitution?

A: The RC14KB100R is classified as obsolete. The ASRM12JB100R is the active equivalent from the same manufacturer, ensuring continued procurement availability and design support.

Q: Are there differences in physical dimensions?

A: Yes. The RC14KB100R measures 0.094" Dia x 0.248" L (2.40mm x 6.30mm), while the ASRM12JB100R measures 0.118" Dia x 0.354" L (3.00mm x 9.00mm). Both are axial packages; verify board layout compatibility before implementation.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RC14KB100R and ASRM12JB100R are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99.

Q: What is the difference between carbon composition and metal film resistors?

A: The RC14KB100R uses carbon composition construction, while the ASRM12JB100R uses metal film construction. Metal film resistors typically offer improved stability, lower noise, and better temperature coefficient performance. Both compositions are suitable for general-purpose circuit applications.
