Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFM14JT75R0 is determined by strict equivalence across the following critical parameters:

• Resistance value: 75 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Power rating: 0.25W / 1/4W (exact match required)
• Composition: Carbon Film (exact match required)
• Package: Axial through-hole (exact match required)
• Temperature coefficient: 0 / -400ppm/°C (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)

Two substitute parts meet these criteria: CF14JT75R0 (manufacturer recommended) and CFM14JA75R0 (parametric equivalent). Both maintain identical electrical specifications and environmental compliance while differing only in physical dimensions and series designation.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the CFM14JT75R0 based on identical resistance, tolerance, power rating, composition, and environmental specifications. Selection between alternatives depends on application-specific constraints:

CF14JT75R0 is designated as the manufacturer-recommended substitute and offers significantly higher inventory availability (83990 units). This part differs in physical dimensions (0.091" Dia x 0.236" L versus 0.067" Dia x 0.130" L) and series designation (CF versus CFM). Physical dimension differences may impact PCB layout compatibility and mechanical fit in space-constrained applications.

CFM14JA75R0 is classified as a parametric equivalent and maintains identical physical dimensions to the main part (0.067" Dia x 0.130" L), ensuring direct mechanical compatibility in existing designs. This part retains the CFM series designation and offers moderate inventory availability (3695 units).

All three parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

Frequently Asked Questions (FAQ)

Q: Can CF14JT75R0 be used as a direct replacement for CFM14JT75R0 in existing circuit designs?

A: CF14JT75R0 is electrically equivalent and maintains identical electrical specifications. However, physical dimensions differ: CF14JT75R0 measures 0.091" Dia x 0.236" L compared to CFM14JT75R0 at 0.067" Dia x 0.130" L. PCB layout compatibility must be verified before substitution, particularly in space-constrained applications or where lead spacing is critical.

Q: What is the difference between a manufacturer-recommended substitute and a parametric equivalent?

A: CF14JT75R0 is designated manufacturer-recommended, indicating Stackpole Electronics Inc formally recognizes this part as an acceptable substitute. CFM14JA75R0 is classified as parametric equivalent, meaning it matches all critical electrical and environmental parameters but may differ in physical characteristics or series designation. Both are valid substitutes based on electrical compatibility.

Q: Are all three parts suitable for applications requiring ROHS3 compliance?

A: Yes. CFM14JT75R0, CF14JT75R0, and CFM14JA75R0 are all ROHS3 compliant and REACH unaffected, meeting regulatory requirements for restricted substance compliance.

Q: Which substitute should be selected for space-constrained PCB designs?

A: CFM14JA75R0 maintains identical physical dimensions to the main part (0.067" Dia x 0.130" L) and is the appropriate choice for designs where component size and lead spacing are critical. CF14JT75R0 features larger dimensions and may not fit existing PCB footprints without layout modification.

Q: Do all substitute parts operate across the same temperature range?

A: Yes. CFM14JT75R0, CF14JT75R0, and CFM14JA75R0 all operate from -55°C to 155°C with identical temperature coefficients (0 / -400ppm/°C), ensuring consistent performance across equivalent thermal environments.
