Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12JAD100R are qualified based on the following electrical and mechanical parameters:

Qualifying Parameters for Substitution:

• Resistance value: 100 Ohms (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.108" Dia × 0.344" L (exact match required)
• Composition: Metal Film (exact match required)
• Operating temperature range: -55°C to 155°C (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)

Variable Parameters Allowing Substitution:

• Tolerance: ±5% (main part) to ±1% (substitute parts) — tighter tolerance is acceptable as it represents improved performance
• Packaging format: Tape & Box (TB) to Cut Tape (CT) — both are standard distribution methods for the same component

The substitute parts RNF12FAD100R and RNF12FTD100R maintain identical electrical specifications and physical form factors while offering improved tolerance performance (±1% vs ±5%) and alternative packaging options.

Parameter Comparison

Engineering Selection Recommendations

All three parts—RNF12JAD100R, RNF12FAD100R, and RNF12FTD100R—are active production components with identical ROHS3 compliance and REACH unaffected status. Selection between these parts should be based on:

Tolerance Requirements: Applications requiring tighter tolerance control (±1%) should specify RNF12FAD100R or RNF12FTD100R. Applications with ±5% tolerance acceptance can use RNF12JAD100R.

Packaging Requirements: RNF12FAD100R and RNF12JAD100R are supplied in Tape & Box format, suitable for mixed-volume production runs. RNF12FTD100R is supplied in Cut Tape format, appropriate for high-volume automated assembly operations.

Inventory Availability: RNF12FTD100R maintains the highest inventory level (18,908 pcs), followed by RNF12FAD100R (754 pcs) and RNF12JAD100R (669 pcs).

Frequently Asked Questions (FAQ)

Q: Can RNF12FAD100R or RNF12FTD100R be used as direct replacements for RNF12JAD100R?

A: Yes. Both substitute parts maintain identical resistance value, power rating, physical dimensions, temperature range, and temperature coefficient. The ±1% tolerance of the substitute parts represents improved accuracy compared to the ±5% tolerance of the main part, making them electrically compatible and functionally superior for applications where tighter tolerance is beneficial or neutral.

Q: What is the difference between Tape & Box (TB) and Cut Tape (CT) packaging?

A: Tape & Box packaging includes a full reel of components on carrier tape with a protective box, suitable for smaller production quantities and mixed-component assembly. Cut Tape packaging provides components on carrier tape cut to specific lengths, optimized for high-volume automated pick-and-place assembly systems. Both formats contain identical components; the difference is in distribution and handling method.

Q: Are there any mechanical compatibility concerns when substituting between these parts?

A: No. All three parts share identical physical dimensions (0.108" Dia × 0.344" L), axial package configuration, and two-termination design. They are mechanically interchangeable in any PCB layout or circuit design.

Q: Do tolerance differences affect circuit performance?

A: Tolerance differences affect component accuracy but not electrical functionality. The ±1% tolerance parts provide tighter resistance value control, which may be advantageous in precision circuits but is not required for applications designed around ±5% tolerance specifications.

Q: Are all three parts compliant with current regulatory requirements?

A: Yes. All three parts maintain ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.
