Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CRL1206-FW-R180ELF is determined by the following critical parameters: resistance value (180 mOhms), tolerance (±1%), package format (1206), composition (thick film), and number of terminations (2). All identified substitute parts match these core electrical and mechanical specifications.

The substitute parts are grouped into two categories based on operational differences:

Upgrade Substitute (RLP73K2BR18FTDF): Matches all primary electrical parameters with identical resistance, tolerance, and power rating. Operating temperature range extends to 155°C. Includes current sense feature designation.

Similar Substitute (RMCF1206FTR180): Matches resistance, tolerance, and package specifications. Power rating is reduced to 0.25W (1/4W). Includes automotive AEC-Q200 qualification. Operating temperature range extends to 155°C.

Parameter Comparison

Engineering Selection Recommendations

RLP73K2BR18FTDF (Upgrade Substitute): This part provides direct electrical equivalence to the CRL1206-FW-R180ELF with identical power rating and extended operating temperature capability to 155°C. Both components maintain ROHS3 compliance and unlimited MSL rating. This substitute is suitable for applications requiring the same thermal and electrical performance with enhanced temperature margin.

RMCF1206FTR180 (Similar Substitute): This part matches the core electrical specifications (resistance, tolerance, temperature coefficient) and package format. The power rating is reduced from 0.5W to 0.25W, requiring thermal design verification for applications operating at maximum power dissipation. The component carries AEC-Q200 automotive qualification and extended operating temperature to 155°C. This substitute is applicable to designs where automotive-grade reliability is required and thermal conditions permit the lower power rating.

Frequently Asked Questions (FAQ)

Q: Can RLP73K2BR18FTDF replace CRL1206-FW-R180ELF in all applications?

A: Yes, RLP73K2BR18FTDF provides electrical and mechanical equivalence. The extended operating temperature range to 155°C offers additional thermal margin. Physical dimensions differ slightly (3.10mm x 1.55mm versus 3.20mm x 1.60mm) and seated height is reduced (0.65mm versus 0.70mm), which may require PCB layout verification for high-density designs.

Q: Is RMCF1206FTR180 suitable as a direct replacement?

A: RMCF1206FTR180 is electrically equivalent for resistance, tolerance, and temperature coefficient. The reduced power rating (0.25W versus 0.5W) requires thermal analysis to confirm the component can dissipate the required power without exceeding temperature limits. Physical dimensions are identical to the main part. This substitute is appropriate for applications with lower power dissipation requirements or where automotive qualification is beneficial.

Q: What are the physical dimension differences between these parts?

A: CRL1206-FW-R180ELF and RMCF1206FTR180 share identical dimensions (3.20mm x 1.60mm length x width, 0.70mm seated height). RLP73K2BR18FTDF has slightly reduced dimensions (3.10mm x 1.55mm length x width, 0.65mm seated height). These differences are within standard 1206 package tolerance but may affect placement in space-constrained layouts.

Q: Are all three parts RoHS compliant?

A: Yes, all three parts are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating. All carry EAR99 ECCN classification and REACH unaffected status.

Q: What is the significance of the "Current Sense" feature on RLP73K2BR18FTDF?

A: The current sense designation indicates the part is optimized for current measurement applications. This does not affect basic substitution compatibility but may indicate enhanced performance characteristics for precision current sensing circuits.
