Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

• Resistance Value: Must be 15.6 kOhms
• Tolerance: Must be ±0.1%
• Package / Case: Must be 0402 (1005 Metric)
• Composition: Must be Thin Film
• Temperature Coefficient: Must be ±25ppm/°C
• RoHS Status: Must be ROHS3 Compliant
• Moisture Sensitivity Level: Must be 1 (Unlimited)

All substitute parts listed meet these core electrical and mechanical parameters. Variations in power rating, operating temperature range, and additional features (such as automotive qualification or anti-sulfur coating) represent upgrades or enhanced specifications that do not prevent substitution but may offer improved performance characteristics for specific applications.

TNPW040215K6BEED (Upgrade Option): Manufactured by Vishay Dale, this part offers the highest power rating (0.13W) and extended operating temperature range (-55°C ~ 175°C). It includes automotive AEC-Q200 qualification, anti-sulfur coating, and moisture resistance. Product status is active with 10313 units in stock. This part is suitable for applications requiring enhanced thermal performance or extended temperature operation.

All substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RN73R1ETTP1562B25 be used as a direct replacement for RN731ETTP1562B25?

A: Yes. Both parts share identical resistance (15.6 kOhms), tolerance (±0.1%), power rating (0.063W), package (0402), composition (thin film), and temperature coefficient (±25ppm/°C). The primary difference is product status: RN731ETTP1562B25 is obsolete while RN73R1ETTP1562B25 is active production. RN73R1ETTP1562B25 adds automotive AEC-Q200 qualification.

Q: What is the difference between the three substitute parts?

A: All three maintain the core electrical specifications (15.6 kOhms, ±0.1%, thin film, ±25ppm/°C). Differences are: RN73R1ETTP1562B25 matches the original power rating (0.063W); RNCF0402BKE15K6 provides 0.1W power rating; TNPW040215K6BEED provides 0.13W power rating and extended temperature range to 175°C. All three include automotive AEC-Q200 qualification.

Q: Are all substitute parts in the same 0402 package?

A: Yes. All parts use the 0402 (1005 Metric) package with identical footprint dimensions (0.039" L x 0.020" W). Physical board layout compatibility is maintained across all substitutes.

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

A: All three substitute parts carry automotive AEC-Q200 qualification. Selection depends on thermal requirements: RN73R1ETTP1562B25 for equivalent performance, RNCF0402BKE15K6 for moderate thermal margin, or TNPW040215K6BEED for maximum thermal performance and extended temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, consistent with the original part specifications.
