Frequently Asked Questions (FAQ)

Q: Can the TLRP2B10WR015FTD replace the TL2BR015F in existing designs without modification?

A: Yes. The TLRP2B10WR015FTD maintains identical resistance (15 mOhms), tolerance (±1%), and 1206 package dimensions. The increased power rating (1W versus 0.25W) provides additional thermal margin without affecting electrical performance. No circuit redesign is required.

Q: What is the primary advantage of the KRL1632E-M-R015-F-T5 over the TLRP2B10WR015FTD?

A: The KRL1632E-M-R015-F-T5 offers superior temperature coefficient stability (±50 ppm/°C versus ±75 ppm/°C), resulting in more precise resistance value maintenance across temperature variations. This is beneficial for precision current sensing applications requiring tighter tolerance control over extended temperature ranges.

Q: Are both substitute parts suitable for automotive applications?

A: Yes. Both the TLRP2B10WR015FTD and KRL1632E-M-R015-F-T5 carry AEC-Q200 automotive qualification, meeting automotive industry reliability and performance standards.

Q: How do the physical dimensions compare between the main part and substitutes?

A: All three parts use the 1206 (3216 Metric) package. The main part (TL2BR015F) measures 0.126" L × 0.063" W with 0.024" maximum seated height. The TLRP2B10WR015FTD measures 0.124" L × 0.057" W with 0.026" maximum seated height. The KRL1632E-M-R015-F-T5 measures 0.126" L × 0.063" W with 0.028" maximum seated height. These minor dimensional variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Why is the TL2BR015F classified as obsolete?

A: The TL2BR015F is listed as obsolete by the manufacturer. The TLRP2B10WR015FTD and KRL1632E-M-R015-F-T5 are active products with ongoing manufacturing support, ensuring long-term availability for new designs and production continuity.

Q: What is the significance of the anti-sulfur coating on the TLRP2B10WR015FTD?

A: Anti-sulfur coating protects the resistor element from sulfur-containing environmental contaminants, extending component reliability in harsh industrial and automotive environments. This feature enhances long-term performance stability in applications exposed to corrosive atmospheres.

Q: Can these parts be used interchangeably in high-precision current sensing circuits?

A: The TLRP2B10WR015FTD is directly interchangeable. The KRL1632E-M-R015-F-T5 is also interchangeable and offers improved precision due to its lower temperature coefficient (±50 ppm/°C), making it preferable for applications requiring tighter tolerance control across temperature variations.
