RN732BTTD7412B05 Equivalent & Substitute Parts

Part Overview

The RN732BTTD7412B05 is a 74.1 kOhms ±0.1% thin film chip resistor in 1206 package manufactured by KOA Speer Electronics, Inc. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The resistor is rated for 0.125W (1/8W) power dissipation with moisture-resistant construction and operates across -55°C to 155°C temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732BTTD7412B05 is determined by the following critical parameters: resistance value (74.1 kOhms), tolerance (±0.1% or better), package type (1206), composition (thin film), and operating temperature range compatibility. The power rating may be equal or higher without affecting circuit functionality, provided the physical dimensions remain compatible with the 1206 footprint.

Two substitute parts meet these criteria:

Direct Substitute (RN73R2BTTD7412B05): Identical resistance, tolerance, package, and composition. Power rating increased to 0.25W (1/4W). Same manufacturer series evolution with active product status and automotive AEC-Q200 qualification.

Upgrade Substitute (PLT1206Z7412LBTS): Identical resistance and package. Tolerance improved to ±0.01% (tighter than original ±0.1%). Power rating increased to 0.4W (2/5W). Different manufacturer (Vishay Dale) with enhanced environmental features.

Parameter Comparison

Engineering Selection Recommendations

RN73R2BTTD7412B05 is the recommended direct substitute for applications requiring continuity with the original RN732BTTD7412B05 specification. This part maintains identical electrical characteristics while offering active product status and automotive AEC-Q200 qualification. It is ROHS3 compliant and provides higher power dissipation capability (0.25W vs. 0.125W) without footprint changes.

PLT1206Z7412LBTS serves as an upgrade option for applications where improved tolerance (±0.01%) and higher power rating (0.4W) provide design margin benefits. This part is active and offers enhanced environmental protection features. However, it is RoHS non-compliant and has a reduced upper operating temperature limit of 125°C compared to 155°C for the original part. Selection of this substitute requires verification that the lower temperature maximum does not conflict with application requirements.

Frequently Asked Questions (FAQ)

Q: Can RN73R2BTTD7412B05 be used as a direct replacement for RN732BTTD7412B05?

A: Yes. Both parts share identical resistance (74.1 kOhms), tolerance (±0.1%), package (1206), composition (thin film), and temperature coefficient (±5ppm/°C). The increased power rating (0.25W vs. 0.125W) does not affect compatibility and provides additional thermal margin.

Q: What is the key difference between the direct substitute and upgrade substitute?

A: RN73R2BTTD7412B05 maintains specification parity with the original part while offering active product status. PLT1206Z7412LBTS improves tolerance to ±0.01% and increases power rating to 0.4W, but operates at a maximum temperature of 125°C instead of 155°C and is RoHS non-compliant.

Q: Are all substitute parts available in the same 1206 package?

A: Yes. All three parts use the 1206 (3216 Metric) package with identical footprint dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm), ensuring PCB layout compatibility.

Q: Does the tolerance improvement in PLT1206Z7412LBTS affect circuit performance?

A: Improved tolerance (±0.01% vs. ±0.1%) reduces resistor value variation and may benefit precision analog circuits. However, this upgrade is only beneficial if the application design specifically requires tighter tolerance control.

Q: What compliance considerations apply to substitute selection?

A: RN73R2BTTD7412B05 is ROHS3 compliant. PLT1206Z7412LBTS is RoHS non-compliant. Applications subject to RoHS regulations must use RN73R2BTTD7412B05 or verify exemption applicability for PLT1206Z7412LBTS.

Q: Are there temperature range limitations when substituting?

A: RN73R2BTTD7412B05 maintains the original -55°C ~ 155°C range. PLT1206Z7412LBTS operates to 125°C maximum. Applications requiring operation above 125°C must use RN73R2BTTD7412B05.
