Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RN732BTTD7682A05 is determined by the following critical parameters: resistance value (76.8 kOhms), tolerance (±0.05%), package type (1206), composition (thin film), temperature coefficient (±5ppm/°C), and moisture resistance. Power rating may be increased without functional impact, provided the package dimensions and electrical characteristics remain compatible. All substitute parts must maintain the same resistance value, tolerance, package footprint, and thin film construction to ensure direct circuit compatibility.

The substitute parts are grouped as follows:

Direct Equivalent (Same Power Rating): RN73R2BTTD7682A05 matches the electrical specifications with identical power rating (0.25W) and maintains the same resistance, tolerance, and package.

Upgrade Options (Enhanced Performance): PLT1206Z7682LBTS and TNPU120676K8AZEN00 provide improved tolerance and/or power ratings while maintaining core electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

RN73R2BTTD7682A05 is the primary direct substitute for the RN732BTTD7682A05. Both parts are manufactured by KOA Speer Electronics, Inc., maintain identical electrical specifications (76.8 kOhms ±0.05%), and are housed in the same 1206 package. The RN73R2BTTD7682A05 is active in production, ROHS3 compliant, and includes automotive AEC-Q200 certification. The increased power rating (0.25W vs. 0.125W) provides additional thermal margin without affecting circuit compatibility.

TNPU120676K8AZEN00 (Vishay Dale) is suitable for applications requiring automotive qualification. This part maintains the same resistance, tolerance, and power rating as the RN73R2BTTD7682A05, includes AEC-Q200 certification, and is ROHS3 compliant. The operating temperature range is reduced to -55°C ~ 125°C compared to the main part's -55°C ~ 155°C specification.

PLT1206Z7682LBTS (Vishay Dale Thin Film) offers the highest power rating (0.4W) and superior tolerance (±0.01%), making it suitable for precision applications. However, this part is RoHS non-compliant and has a reduced operating temperature range (-55°C ~ 125°C). Selection of this part requires verification of RoHS compliance requirements for the end application.

Frequently Asked Questions (FAQ)

Q: Can RN73R2BTTD7682A05 be used as a direct replacement for RN732BTTD7682A05?

A: Yes. Both parts share identical resistance (76.8 kOhms), tolerance (±0.05%), package (1206), and thin film composition. The RN73R2BTTD7682A05 has a higher power rating (0.25W vs. 0.125W), which is compatible with the original circuit design. The RN73R2BTTD7682A05 is active in production and ROHS3 compliant.

Q: What are the key differences between the substitute parts?

A: RN73R2BTTD7682A05 and TNPU120676K8AZEN00 maintain identical electrical specifications to the main part with equivalent power ratings (0.25W). TNPU120676K8AZEN00 includes anti-sulfur protection and automotive AEC-Q200 certification. PLT1206Z7682LBTS provides enhanced tolerance (±0.01%) and higher power rating (0.4W) but is RoHS non-compliant and has a reduced operating temperature range.

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

A: Yes. All substitute parts use the 1206 (3216 Metric) package with identical footprint dimensions (0.126" L x 0.063" W / 3.20mm x 1.60mm). All are available in Tape & Reel (TR) packaging for automated assembly.

Q: What is the impact of the reduced operating temperature range in TNPU120676K8AZEN00 and PLT1206Z7682LBTS?

A: Both parts operate from -55°C to 125°C, compared to the main part's -55°C to 155°C range. Applications requiring operation above 125°C must use RN732BTTD7682A05 or RN73R2BTTD7682A05.

Q: Which substitute part should be selected for automotive applications?

A: Both RN73R2BTTD7682A05 and TNPU120676K8AZEN00 carry AEC-Q200 certification. RN73R2BTTD7682A05 maintains the full operating temperature range (-55°C ~ 155°C), while TNPU120676K8AZEN00 is limited to -55°C ~ 125°C but includes anti-sulfur protection.

Q: Is RoHS compliance a factor in substitute selection?

A: RN73R2BTTD7682A05 and TNPU120676K8AZEN00 are ROHS3 compliant. PLT1206Z7682LBTS is RoHS non-compliant. Applications subject to RoHS regulations must exclude PLT1206Z7682LBTS.
