Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PCF14JT300R is determined by strict equivalence across the following critical parameters: resistance value (300 Ohms), tolerance (±5%), power rating (0.25W), composition (carbon film), temperature coefficient (0 / -400ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (ROHS3, REACH unaffected).

The identified substitutes maintain identical electrical specifications and regulatory certifications. Packaging format differences (Tape & Reel versus Cut Tape, axial versus axial with radial bend capability) represent the primary distinction between the main part and substitute options. Physical dimensions vary between the standard CF series and the compact CFM series, reflecting different form factors while preserving electrical performance.

Parameter Comparison

Engineering Selection Recommendations

All three parts—PCF14JT300R, CF14JT300R, and CFM14JT300R—are active products from Stackpole Electronics Inc with identical ROHS3 compliance and REACH unaffected status. Selection between these parts depends on packaging and form factor requirements rather than electrical performance.

The PCF14JT300R in Tape & Reel packaging is suitable for high-volume automated assembly processes. The CF14JT300R in Cut Tape format provides the same standard dimensions (0.091" Dia x 0.236" L) and supports both axial and radial bend configurations, offering flexibility for manual or semi-automated placement. The CFM14JT300R represents a compact alternative within the CFM series, featuring reduced physical dimensions (0.067" Dia x 0.130" L) while maintaining identical electrical specifications, making it appropriate for space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can CF14JT300R replace PCF14JT300R in my design?

A: Yes. Both parts share identical electrical specifications (300 Ohms ±5%, 0.25W, carbon film composition, temperature coefficient, and operating range) and regulatory compliance. The primary difference is packaging format: PCF14JT300R uses Tape & Reel while CF14JT300R uses Cut Tape. Verify your assembly process compatibility with the Cut Tape format.

Q: What is the difference between CF14JT300R and CFM14JT300R?

A: Both maintain identical electrical performance and compliance. The CFM14JT300R is a compact variant with smaller physical dimensions (0.067" Dia x 0.130" L versus 0.091" Dia x 0.236" L). Select CFM14JT300R for applications requiring reduced component footprint; select CF14JT300R for standard form factor requirements.

Q: Are all three parts suitable for the same operating temperature range?

A: Yes. All three parts operate across -55°C to 155°C with identical temperature coefficient specifications (0 / -400ppm/°C).

Q: Do packaging differences affect electrical performance?

A: No. Packaging format (Tape & Reel versus Cut Tape) and physical dimensions do not alter electrical characteristics. All three parts deliver identical resistance, tolerance, power rating, and thermal performance.

Q: Which part should I select for high-volume production?

A: PCF14JT300R in Tape & Reel packaging is optimized for automated assembly lines. CF14JT300R in Cut Tape format supports flexible assembly methods. Evaluate your production equipment and volume requirements to determine the most suitable option.
