Mandatory Matching Parameters:

• Resistance value: 36 kOhms
• Tolerance: ±0.1%
• Package: 0603 (1608 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Power rating: Equal to or greater than 0.063W
• Operating temperature range: Must encompass or exceed -55°C ~ 155°C
• Product status: Active or obsolete
• Certifications and compliance: May differ based on application requirements

Two substitute parts meet these criteria with varying power ratings and certifications, enabling selection based on specific application demands and regulatory requirements.

Engineering Selection Recommendations

RN73R1JTTD3602B25 (Direct Substitute - KOA Speer Electronics, Inc.)

This part is the primary equivalent for RN731JTTD3602B25 replacement. It maintains identical electrical specifications (36 kOhms, ±0.1%, ±25ppm/°C) and physical package dimensions. The power rating increase from 0.063W to 0.1W provides enhanced thermal margin without affecting circuit performance. Active product status ensures long-term availability. ROHS3 compliance aligns with current regulatory requirements. Automotive AEC-Q200 qualification adds reliability assurance for demanding applications. Tape & Reel packaging supports automated assembly processes.

TNPW060336K0BETA (Upgrade Substitute - Vishay Dale)

This part serves as an alternative for applications requiring military-grade specifications. Electrical parameters match the main part identically. The 0.1W power rating provides equivalent thermal performance to RN73R1JTTD3602B25. Operating temperature range of -55°C to 125°C is narrower than the main part's -55°C to 155°C specification; applications requiring operation above 125°C must use RN73R1JTTD3602B25. RoHS non-compliance and REACH-affected status require verification against design and procurement requirements. Military classification indicates enhanced quality and reliability standards.

Frequently Asked Questions (FAQ)

Q: Can RN73R1JTTD3602B25 directly replace RN731JTTD3602B25 in all applications?

A: Yes. Both parts share identical resistance (36 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), package (0603), and operating temperature range (-55°C ~ 155°C). The higher power rating (0.1W vs. 0.063W) of RN73R1JTTD3602B25 is a non-limiting upgrade that improves thermal performance.

Q: What is the key difference between RN73R1JTTD3602B25 and TNPW060336K0BETA?

A: Both provide 0.1W power rating and identical electrical specifications. The primary difference is the operating temperature range: RN73R1JTTD3602B25 operates to 155°C, while TNPW060336K0BETA operates to 125°C. Additionally, TNPW060336K0BETA carries military classification and RoHS non-compliance status.

Q: Are there physical dimension differences between these parts?

A: RN731JTTD3602B25 and RN73R1JTTD3602B25 have identical dimensions (0.063" L x 0.031" W). TNPW060336K0BETA has a slightly wider dimension (0.063" L x 0.033" W). All three fit standard 0603 footprints; verify PCB layout clearances for TNPW060336K0BETA in space-constrained designs.

Q: Which substitute is recommended for automotive applications?

A: RN73R1JTTD3602B25 carries AEC-Q200 automotive qualification and ROHS3 compliance, making it the specified choice for automotive designs. TNPW060336K0BETA lacks automotive certification.

Q: What is the impact of RoHS compliance differences?

A: RN731JTTD3602B25 and RN73R1JTTD3602B25 are ROHS3 compliant. TNPW060336K0BETA is RoHS non-compliant. Design and procurement requirements must be verified to determine if RoHS compliance is mandatory for the application.

Q: Can TNPW060336K0BETA be used in applications requiring 155°C operation?

A: No. TNPW060336K0BETA maximum operating temperature is 125°C. Applications requiring operation above 125°C must use RN73R1JTTD3602B25 or RN731JTTD3602B25.
