Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CSRN2512FTR110 is determined by strict equivalence across the following parameters:

• Resistance value: 110 mOhms
• Tolerance: ±1%
• Power rating: 2W
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Moisture sensitivity level: 1 (Unlimited)
• RoHS compliance: ROHS3 Compliant

The substitute part RLP73K3AR11FTDF meets all these criteria and is therefore classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the CSRN2512FTR110 and RLP73K3AR11FTDF are active production parts with ROHS3 compliance and identical electrical specifications. The RLP73K3AR11FTDF from TE Connectivity Passive Product offers higher inventory availability (24,184 pieces) compared to the Stackpole part (767 pieces). Both parts meet the same regulatory requirements and certifications. The maximum seated height difference of 0.005" (0.14mm) between the two parts is within typical PCB assembly tolerances for 2512 package components. Selection between these parts should be based on supply chain requirements and inventory status.

Frequently Asked Questions (FAQ)

Q: Can RLP73K3AR11FTDF be used as a direct replacement for CSRN2512FTR110?

A: Yes. Both parts share identical electrical specifications (110 mOhms ±1%, 2W, ±200ppm/°C), the same 2512 package footprint, and equivalent environmental ratings. The seated height difference of 0.005" is within standard PCB assembly tolerances.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, carry MSL 1 (Unlimited) moisture sensitivity rating, and are REACH unaffected. The CSRN2512FTR110 includes AEC-Q200 automotive qualification; this specification is not listed for the TE Connectivity part in the provided data.

Q: What is the primary reason to consider the substitute part?

A: The RLP73K3AR11FTDF offers significantly higher inventory availability (24,184 pieces versus 767 pieces), making it suitable for high-volume production requirements or extended lead time mitigation.

Q: Will the substitute part fit the same PCB layout?

A: Yes. Both parts use the identical 2512 (6432 Metric) package with matching length and width dimensions (0.250" x 0.124"). The maximum seated height difference of 0.005" does not affect standard PCB assembly processes.

Q: Are both parts suitable for current sense applications?

A: Yes. Both parts are specified as current sense thick film resistors and are suitable for this application category.
