Key Parameters

Substitute Part Grouping Explanation

The ASRM12JA6K80 qualifies as a substitute for the RC14JB6K80 based on the following critical parameters:

• Resistance Value: Both parts are 6.8 kOhms
• Tolerance: Both maintain ±5% tolerance
• Package Configuration: Both use axial through-hole packaging
• Compliance: Both are ROHS3 compliant and REACH unaffected
• Termination Count: Both have 2 terminations

The ASRM12JA6K80 represents an upgrade path, offering increased power handling (0.5W vs 0.25W) and an extended operating temperature range (-55°C to 155°C vs -55°C to 125°C), while maintaining the same electrical specifications required for the original application.

Parameter Comparison

Engineering Selection Recommendations

The ASRM12JA6K80 is the recommended substitute for the obsolete RC14JB6K80. Both parts maintain identical electrical specifications (6.8 kOhms, ±5% tolerance) and are manufactured by the same supplier. The substitute offers enhanced reliability through active product status, increased power dissipation capability (0.5W vs 0.25W), and an extended operating temperature range (155°C maximum vs 125°C maximum). Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements. The substitute's metal film composition and flame retardant coating provide additional safety characteristics compared to the original carbon composition design. Physical dimensions are larger for the substitute, requiring verification of PCB layout compatibility before implementation.

Frequently Asked Questions (FAQ)

Q: Can the ASRM12JA6K80 directly replace the RC14JB6K80 in all applications?

A: The ASRM12JA6K80 maintains the same resistance value (6.8 kOhms) and tolerance (±5%), making it electrically compatible. However, the substitute is physically larger (0.118" Dia x 0.354" L vs 0.094" Dia x 0.248" L), requiring verification that PCB layout and mechanical constraints accommodate the increased dimensions.

Q: What are the key differences between these two resistors?

A: The primary differences are power rating (0.5W vs 0.25W), composition (metal film vs carbon composition), operating temperature range (-55°C to 155°C vs -55°C to 125°C), and product status (active vs obsolete). The substitute includes flame retardant coating and safety features not present in the original.

Q: Are both parts RoHS compliant?

A: Yes, both the RC14JB6K80 and ASRM12JA6K80 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: What is the temperature coefficient difference?

A: The original RC14JB6K80 does not specify a temperature coefficient. The ASRM12JA6K80 substitute specifies 0 / -1800ppm/°C, indicating superior temperature stability characteristics typical of metal film resistors.

Q: Does the substitute's higher power rating affect circuit performance?

A: The higher power rating (0.5W vs 0.25W) does not negatively affect circuit performance. It provides additional thermal margin and reliability headroom for the same electrical specifications, reducing thermal stress during operation.
