Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CF18JA180R is determined by the following critical parameters:

• Resistance Value: Must be 180 Ohms
• Tolerance: Must be ±5% or tighter
• Composition: Carbon Film
• Package Type: Axial through-hole
• Temperature Coefficient: 0 / -400ppm/°C
• Operating Temperature Range: -55°C to 155°C minimum
• RoHS Compliance: ROHS3 Compliant

The CFM14JA180R qualifies as a substitute part because it maintains identical resistance, tolerance, composition, package type, temperature coefficient, and operating temperature range. The primary difference is the power rating upgrade from 1/8W to 1/4W, which represents a functional enhancement rather than a limitation. Both parts are manufactured by Stackpole Electronics Inc and share the same physical dimensions and termination configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the CF18JA180R and CFM14JA180R are active production parts with full ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. The CFM14JA180R provides a higher power dissipation capability (1/4W versus 1/8W) while maintaining all other electrical and mechanical specifications. Selection between these parts should be based on circuit power dissipation requirements and packaging format availability. The CF18JA180R is suitable for applications with lower power budgets, while the CFM14JA180R accommodates designs with higher thermal margins or increased power dissipation headroom.

Frequently Asked Questions (FAQ)

Q: Can CFM14JA180R replace CF18JA180R in all applications?

A: The CFM14JA180R is electrically and mechanically compatible with CF18JA180R. The higher power rating (1/4W versus 1/8W) does not create compatibility issues and provides additional thermal margin. Physical dimensions are identical, allowing direct board-level substitution.

Q: What is the primary difference between these two parts?

A: The primary difference is the power rating. CF18JA180R is rated for 0.125W dissipation, while CFM14JA180R is rated for 0.25W. All other specifications—resistance, tolerance, temperature coefficient, operating range, and physical dimensions—are identical.

Q: Are both parts RoHS compliant?

A: Yes, both CF18JA180R and CFM14JA180R are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Do these parts have different packaging formats?

A: Both parts use axial through-hole packaging with identical physical dimensions (0.067" diameter x 0.130" length). The main packaging difference is the supplier format: CF18JA180R is supplied in Tape & Box format, while CFM14JA180R is supplied in Cut Tape format.

Q: What temperature range do these resistors support?

A: Both parts operate across -55°C to 155°C, with a temperature coefficient of 0 / -400ppm/°C, providing stable performance across industrial and commercial temperature environments.
