Substitute Part Grouping Explanation

Substitution of the TNPW1206249KBETY with the RG3216P-2493-B-T5 is valid based on the following matching electrical and mechanical parameters:

• Identical resistance value: 249 kOhms
• Identical tolerance: ±0.1%
• Identical power rating: 0.25W (1/4W)
• Identical composition: Thin Film
• Identical package: 1206 (3216 Metric)
• Identical temperature coefficient: ±25ppm/°C
• Identical number of terminations: 2
• Identical moisture sensitivity level: 1 (Unlimited)

The substitute part maintains all critical electrical specifications required for direct replacement. Physical dimensions are compatible, with the substitute part featuring a lower maximum seated height (0.020" vs 0.026"), which presents no compatibility issues for standard PCB assembly.

Parameter Comparison

Engineering Selection Recommendations

The RG3216P-2493-B-T5 serves as a direct electrical and mechanical substitute for the TNPW1206249KBETY. Selection between these parts should be based on application requirements and regulatory compliance:

The TNPW1206249KBETY is suitable for applications requiring military-grade specifications with an operating temperature range of -55°C to 125°C.

The RG3216P-2493-B-T5 is suitable for applications requiring automotive qualification (AEC-Q200), extended operating temperature range (-55°C to 155°C), anti-sulfur protection, and RoHS3 compliance. This part is also REACH unaffected, providing regulatory advantages in certain supply chain contexts.

Both parts are active products with adequate inventory availability. The choice between them depends on whether the application requires automotive qualification, extended temperature performance, or specific regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can the RG3216P-2493-B-T5 replace the TNPW1206249KBETY in all applications?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical resistance, tolerance, power rating, composition, package, temperature coefficient, and termination specifications. The substitute part has a lower maximum seated height, which is compatible with standard PCB assembly. Selection should consider application-specific requirements such as automotive qualification, extended temperature range, or regulatory compliance needs.

Q: What is the difference in operating temperature range?

A: The TNPW1206249KBETY operates from -55°C to 125°C. The RG3216P-2493-B-T5 operates from -55°C to 155°C, providing a 30°C extended upper temperature limit. This difference is relevant only if the application requires operation above 125°C.

Q: Are there RoHS compliance differences?

A: Yes. The TNPW1206249KBETY is RoHS non-compliant, while the RG3216P-2493-B-T5 is ROHS3 compliant. Applications subject to RoHS regulations should use the RG3216P-2493-B-T5.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive electronics qualification standard. The RG3216P-2493-B-T5 carries this rating, indicating suitability for automotive applications. The TNPW1206249KBETY does not carry this certification.

Q: Are the physical dimensions compatible?

A: Yes. Both parts use the 1206 (3216 Metric) package with identical length (0.126") and width (0.063"). The RG3216P-2493-B-T5 has a lower maximum seated height (0.020" vs 0.026"), which presents no compatibility issues for standard PCB assembly.

Q: What is the significance of anti-sulfur protection?

A: The RG3216P-2493-B-T5 includes anti-sulfur protection, which provides enhanced resistance to sulfur-containing environments. This feature is relevant for applications in industrial or harsh environments where sulfur exposure is a concern.
