Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RNF12FAD100R are qualified based on the following electrical and mechanical parameters:

• Resistance value: 100 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W / 1/2W (exact match required)
• Composition: Metal Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Package type: Axial (exact match required)
• Operating temperature range: Minimum -55°C ~ 155°C (equal or wider range acceptable)
• Compliance: ROHS3 Compliant (maintained across all substitutes)

Packaging format (Tape & Box vs. Cut Tape) and physical dimensions may vary within the axial package category while maintaining electrical equivalence. All substitute parts maintain identical electrical performance and safety certifications.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence with the RNF12FAD100R.

RNF12FTD100R is a direct electrical equivalent from the same manufacturer with identical dimensions and electrical specifications. The primary difference is packaging format (Cut Tape vs. Tape & Box), making it suitable for applications where tape reel format is preferred.

RNMF12FTD100R is a manufacturer-recommended substitute from Stackpole Electronics Inc within the RNMF (Mini) series. It maintains all electrical parameters but features reduced physical dimensions (0.093" Dia x 0.250" L vs. 0.108" Dia x 0.344" L). This substitute is applicable where space constraints require a smaller form factor without compromising electrical performance.

CMF55100R00FKEB is a manufacturer-recommended substitute from Vishay Dale. It maintains all electrical parameters and adds moisture-resistant features. The operating temperature range extends to 175°C (vs. 155°C for Stackpole parts). Physical dimensions are further reduced (0.090" Dia x 0.240" L). This substitute is applicable where extended temperature operation or moisture resistance is required.

Frequently Asked Questions (FAQ)

Q: Can RNF12FTD100R be used as a direct replacement for RNF12FAD100R?

A: Yes. RNF12FTD100R is electrically and mechanically identical to RNF12FAD100R. The only difference is packaging format (Cut Tape vs. Tape & Box). Both parts have identical dimensions, resistance, tolerance, power rating, and temperature specifications.

Q: What is the difference between RNF12FAD100R and RNMF12FTD100R?

A: Both parts are electrically equivalent with 100 Ohms ±1% at 0.5W and identical temperature coefficients. RNMF12FTD100R is a miniature variant with reduced physical dimensions (0.093" Dia x 0.250" L vs. 0.108" Dia x 0.344" L). Use RNMF12FTD100R when space constraints require a smaller form factor.

Q: Can CMF55100R00FKEB replace RNF12FAD100R in all applications?

A: CMF55100R00FKEB is electrically equivalent and maintains all required electrical parameters. It features moisture-resistant properties and an extended operating temperature range to 175°C. Physical dimensions are smaller (0.090" Dia x 0.240" L). Verify PCB layout compatibility due to dimensional differences before substitution.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RNF12FTD100R, RNMF12FTD100R, and CMF55100R00FKEB are all ROHS3 compliant and REACH unaffected, maintaining regulatory equivalence with RNF12FAD100R.

Q: What packaging formats are available for these 100 Ohm resistors?

A: RNF12FAD100R is supplied in Tape & Box format. RNF12FTD100R, RNMF12FTD100R, and CMF55100R00FKEB are supplied in Cut Tape format. Select based on assembly process requirements and inventory management preferences.

Q: Do physical dimension differences affect circuit performance?

A: No. Physical dimension differences do not affect electrical performance. All parts maintain identical resistance, tolerance, temperature coefficient, and power rating. Verify PCB layout and lead spacing compatibility when substituting parts with different dimensions.
