CFF12JA100R Equivalent & Substitute Parts

Part Overview

The CFF12JA100R is a 100 Ohm, ±5% tolerance, 0.5W (1/2W) through-hole axial resistor manufactured by Stackpole Electronics Inc. This carbon film resistor features flame-proof construction and safety certification, designed for general-purpose electronic applications requiring reliable fixed resistance in axial package format. The part is currently active in production with 2249 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same resistance value, tolerance, power rating, and package type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CFF12JA100R is determined by strict equivalence across the following critical parameters:

• Electrical Parameters: Resistance value (100 Ohms), tolerance (±5%), and power rating (0.5W / 1/2W) must be identical
• Physical Parameters: Package type (Axial), physical dimensions (0.106" Dia x 0.335" L), and number of terminations (2) must match
• Material & Composition: Carbon film construction is required
• Environmental Specifications: Operating temperature range (-55°C ~ 155°C) and temperature coefficient (0 / -400ppm/°C) must be maintained
• Compliance: RoHS3 compliance and REACH unaffected status must be preserved

The CF12JA100R meets all substitution criteria. Packaging differs (Cut Tape vs. Tape & Box), but this represents a logistics variation only and does not affect electrical or mechanical compatibility. Both parts are manufactured by Stackpole Electronics Inc and maintain identical core specifications.

Parameter Comparison

Engineering Selection Recommendations

Both CFF12JA100R and CF12JA100R are active production parts from Stackpole Electronics Inc with full RoHS3 compliance and REACH unaffected status. Selection between these parts should be based on packaging requirements and inventory availability. The CFF12JA100R features flame-proof construction, while the CF12JA100R includes flame-retardant coating; both provide safety-rated performance suitable for standard through-hole applications. The primary distinction is packaging format: Cut Tape (CT) for CFF12JA100R and Tape & Box (TB) for CF12JA100R. Choose based on assembly process requirements and supply chain logistics.

Frequently Asked Questions (FAQ)

Q: Can CF12JA100R be used as a direct replacement for CFF12JA100R in circuit design?

A: Yes. Both parts maintain identical electrical specifications (100 Ohms, ±5%, 0.5W), physical dimensions (0.106" Dia x 0.335" L), operating temperature range (-55°C ~ 155°C), and compliance certifications (RoHS3, REACH unaffected). The parts are electrically and mechanically interchangeable.

Q: What is the difference between flame-proof and flame-retardant coating?

A: CFF12JA100R features flame-proof construction, while CF12JA100R includes flame-retardant coating. Both provide safety-rated performance. Selection depends on specific application safety requirements and design specifications.

Q: Does packaging format affect electrical performance?

A: No. Cut Tape (CT) and Tape & Box (TB) packaging formats are logistics variations only. They do not affect electrical characteristics, mechanical fit, or performance in circuit applications.

Q: Are both parts suitable for high-temperature applications?

A: Yes. Both CFF12JA100R and CF12JA100R operate across the identical temperature range of -55°C ~ 155°C with a temperature coefficient of 0 / -400ppm/°C, making them suitable for applications within these environmental specifications.

Q: Which part should be selected based on current inventory?

A: CFF12JA100R has 2249 units in stock, while CF12JA100R has 747 units available. Inventory selection should align with production volume requirements and supply chain planning.
