Substitute Part Grouping Explanation

Substitute parts for the RNF18FAD2K00 are classified based on the following substitution criteria:

Direct Equivalent (Same Electrical & Mechanical Specifications):

• RNF18FTD2K00: Identical electrical parameters (2 kOhms, ±1%, 0.125W, ±100ppm/°C, -55°C to 155°C). Differs only in packaging format (Cut Tape vs. Tape & Box). Physical dimensions and termination count remain unchanged. This substitution is valid for applications where packaging format does not impact assembly or procurement workflows.

Upgrade Substitute (Enhanced Power Rating):

• RNMF14FTC2K00: Maintains core electrical specifications (2 kOhms, ±1%, -55°C to 155°C) but provides increased power rating (0.25W / 1/4W vs. 0.125W / 1/8W). Features improved temperature coefficient (±50ppm/°C vs. ±100ppm/°C). Physical dimensions are nearly identical (0.070" Dia vs. 0.071" Dia). This substitution is applicable when higher power dissipation capability or tighter temperature stability is required.

All substitutes maintain identical resistance value, tolerance, composition, axial package configuration, compliance certifications (ROHS3, REACH Unaffected), and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

RNF18FTD2K00 Selection Criteria: Select this direct equivalent when packaging format change from Tape & Box to Cut Tape is acceptable for procurement and assembly processes. All electrical and mechanical specifications remain identical. This option provides significantly higher inventory availability (46,448 units vs. 684 units). Both parts maintain active production status and full ROHS3 compliance.

RNMF14FTC2K00 Selection Criteria: Select this upgrade substitute when circuit design permits increased power dissipation capability (0.25W vs. 0.125W) or when improved temperature stability is required (±50ppm/°C vs. ±100ppm/°C). Physical dimensions are compatible with standard axial component footprints. This option offers the highest inventory availability (68,963 units) and maintains active production status with full ROHS3 compliance. The RNMF series designation indicates mini-form factor construction.

All three parts are manufactured by Stackpole Electronics Inc, maintain identical resistance and tolerance specifications, and comply with ROHS3 and REACH requirements.

Frequently Asked Questions (FAQ)

Q: Can RNF18FTD2K00 be used as a direct replacement for RNF18FAD2K00? A: Yes. Both parts share identical electrical specifications (2 kOhms, ±1%, 0.125W, ±100ppm/°C) and physical dimensions. The only difference is packaging format (Cut Tape vs. Tape & Box). Substitution is valid provided packaging format does not conflict with assembly or procurement requirements.

Q: What is the primary difference between RNF18FAD2K00 and RNMF14FTC2K00? A: The RNMF14FTC2K00 provides double the power rating (0.25W vs. 0.125W) and superior temperature coefficient (±50ppm/°C vs. ±100ppm/°C). Physical dimensions are nearly identical. Resistance, tolerance, and operating temperature range remain unchanged. This substitution is applicable when higher power dissipation or tighter temperature stability is required.

Q: Are all substitute parts ROHS3 compliant? A: Yes. RNF18FAD2K00, RNF18FTD2K00, and RNMF14FTC2K00 are all ROHS3 compliant and REACH unaffected.

Q: What is the difference between RNF and RNMF series designations? A: RNMF indicates mini-form factor construction with enhanced specifications (higher power rating, improved temperature coefficient). RNF represents standard form factor. Both are axial metal film resistors from Stackpole Electronics Inc.

Q: Can RNMF14FTC2K00 be used in applications originally designed for RNF18FAD2K00? A: Yes, provided the circuit design accommodates the increased power rating and improved temperature coefficient. Physical dimensions are compatible with standard axial component footprints. The upgrade substitute offers enhanced performance characteristics.

Q: Which substitute part offers the best inventory availability? A: RNMF14FTC2K00 provides the highest inventory level (68,963 units), followed by RNF18FTD2K00 (46,448 units). RNF18FAD2K00 has limited availability (684 units).
