Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CF18JA75R0 is determined by the following critical parameters:

• Resistance Value: Must be 75 Ohms
• Tolerance: Must be ±5%
• Composition: Must be Carbon Film
• Package Type: Must be Axial
• Operating Temperature Range: Must support -55°C to 155°C
• Temperature Coefficient: Must be 0 / -400ppm/°C
• RoHS Compliance: Must maintain ROHS3 Compliant status

The identified substitute CFM14JA75R0 maintains all critical electrical parameters while offering an increased power rating of 0.25W (1/4W). This upgrade substitution is valid because the higher power rating does not compromise circuit performance in applications designed for the 1/8W specification; it provides additional thermal margin and reliability headroom.

Parameter Comparison

Engineering Selection Recommendations

Both CF18JA75R0 and CFM14JA75R0 are Active products manufactured by Stackpole Electronics Inc and maintain full ROHS3 compliance and REACH Unaffected status. The CFM14JA75R0 represents an upgrade path with doubled power dissipation capacity (0.25W versus 0.125W) while preserving all electrical characteristics. Selection between these parts should be based on application power requirements and packaging format availability. The higher inventory level of CFM14JA75R0 (3695 units) may support extended production schedules or supply chain continuity objectives.

Frequently Asked Questions (FAQ)

Q: Can CFM14JA75R0 be used as a direct replacement for CF18JA75R0?

A: Yes. The CFM14JA75R0 maintains identical resistance value (75 Ohms), tolerance (±5%), composition (Carbon Film), axial package configuration, and operating temperature range (-55°C to 155°C). The increased power rating (0.25W versus 0.125W) does not create incompatibility in circuits designed for the 1/8W specification.

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

A: The primary difference is power rating. CF18JA75R0 is rated for 0.125W (1/8W) dissipation, while CFM14JA75R0 is rated for 0.25W (1/4W). All other electrical and mechanical parameters remain identical.

Q: Are the physical dimensions identical?

A: Yes. Both parts share identical axial package dimensions of 0.067" diameter by 0.130" length (1.70mm x 3.30mm).

Q: Do packaging format differences affect electrical performance?

A: No. CF18JA75R0 is supplied in Tape & Box (TB) format, while CFM14JA75R0 is supplied in Cut Tape (CT) format. Packaging format does not affect electrical characteristics or performance.

Q: Are both parts compliant with current regulatory requirements?

A: Yes. Both CF18JA75R0 and CFM14JA75R0 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory standards.
