Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FTR620 is determined by strict equivalence across the following critical parameters:

• Resistance value: 620 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The RLP73K3AR62FTDF from TE Connectivity Passive Product meets all these parameters and qualifies as a direct substitute. Both parts share identical electrical specifications and package dimensions, enabling pin-for-pin replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2512FTR620 and RLP73K3AR62FTDF are active production parts with ROHS3 compliance and MSL 1 rating. The RLP73K3AR62FTDF offers higher inventory availability (2106 units in stock versus 1022 units). The maximum seated height differs by 0.005" (0.14mm), which may be a consideration in space-constrained applications but does not affect electrical performance. Both parts are suitable for direct substitution in current sense applications requiring automotive-grade reliability.

Frequently Asked Questions (FAQ)

Q: Can the RLP73K3AR62FTDF replace the CSRN2512FTR620 in automotive applications?

A: Yes. Both parts carry identical electrical specifications, package dimensions, and operating temperature ranges. The RLP73K3AR62FTDF is a direct substitute for the CSRN2512FTR620 in automotive circuits.

Q: What is the significance of the height difference between these parts?

A: The CSRN2512FTR620 has a maximum seated height of 0.028" (0.70mm), while the RLP73K3AR62FTDF measures 0.033" (0.84mm). This 0.005" difference is within typical PCB assembly tolerances and does not affect electrical performance. Verify clearance in applications with strict height constraints.

Q: Are both parts RoHS compliant?

A: Yes. Both the CSRN2512FTR620 and RLP73K3AR62FTDF are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What determines substitution eligibility for this 620 mOhms resistor?

A: Substitution requires matching resistance value (620 mOhms), tolerance (±1%), power rating (2W), package type (2512), composition (thick film), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C ~ 155°C).

Q: Can these parts be used interchangeably in tape and reel packaging?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging and are compatible with standard pick-and-place assembly equipment.
