Key Parameters

Substitute Part Grouping Explanation

Substitution of the TL3AR005F is determined by the following critical parameters: resistance value (5 mOhms), tolerance (±1%), package type (2512 / 6432 Metric), and functional classification (current sense). The substitute parts identified maintain these core electrical and mechanical specifications.

Substitutes are grouped into two categories:

Direct Equivalents: Parts that maintain identical electrical specifications and package dimensions, differing only in product status or packaging format.

Functional Equivalents: Parts that maintain core electrical specifications (resistance, tolerance, package) but may feature enhanced power ratings, improved temperature coefficients, or additional features while remaining compatible with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

TL3AR005FTDG serves as the direct equivalent to TL3AR005F, maintaining identical electrical and mechanical specifications. Both parts are classified as obsolete. This substitute is suitable for applications requiring exact parameter matching and is available in cut tape packaging.

TLRP3A20WR005FTE is a manufacturer-recommended substitute offering enhanced specifications. This part maintains the 5 mOhms resistance and ±1% tolerance while providing doubled power rating (2W versus 1W). The part is classified as active product status, ensuring long-term availability. The operating temperature range is reduced to -55°C ~ 170°C (versus -65°C ~ 170°C), and temperature coefficient is ±100ppm/°C. This substitute is appropriate for applications where increased power dissipation capability is beneficial or where extended low-temperature operation below -55°C is not required. Packaging is supplied in tape and reel format.

CSNL2512FT5L00 is a cross-manufacturer substitute from Stackpole Electronics Inc, classified as active product status. This part maintains 5 mOhms resistance, ±1% tolerance, and 2512 package specifications. The power rating is 2W, and the temperature coefficient is ±50ppm/°C, representing superior temperature stability compared to the original part. The operating temperature range is -55°C ~ 170°C. This substitute includes moisture-resistant features and is available in both cut tape and Digi-Reel® packaging formats, providing procurement flexibility.

All substitute parts maintain ROHS3 compliance, moisture sensitivity level 1, and are suitable for current sense applications. Selection between substitutes depends on power dissipation requirements, temperature stability needs, and packaging format preferences.

Frequently Asked Questions (FAQ)

Q: Can TL3AR005FTDG be used as a direct replacement for TL3AR005F?

A: Yes. TL3AR005FTDG maintains identical electrical specifications (5 mOhms, ±1%, 1W) and mechanical package (2512 / 6432 Metric). Both parts are obsolete. The primary difference is packaging format (both cut tape) and inventory availability.

Q: What is the primary advantage of TLRP3A20WR005FTE over the original TL3AR005F?

A: TLRP3A20WR005FTE provides doubled power rating (2W versus 1W) while maintaining the same resistance value and tolerance. The part is active product status, ensuring continued availability. The operating temperature minimum is -55°C instead of -65°C.

Q: Is CSNL2512FT5L00 compatible with TL3AR005F applications?

A: Yes. CSNL2512FT5L00 maintains the same resistance (5 mOhms), tolerance (±1%), and package (2512). The 2W power rating provides increased margin over the original 1W specification. The temperature coefficient is ±50ppm/°C, superior to the original ±75ppm/°C. The operating temperature range is -55°C ~ 170°C.

Q: What packaging options are available for substitutes?

A: TL3AR005FTDG is supplied in cut tape format. TLRP3A20WR005FTE is supplied in tape and reel format. CSNL2512FT5L00 is available in both cut tape and Digi-Reel® formats.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts (TL3AR005FTDG, TLRP3A20WR005FTE, and CSNL2512FT5L00) are ROHS3 compliant with moisture sensitivity level 1 (unlimited).

Q: Which substitute has the best temperature coefficient performance?

A: CSNL2512FT5L00 features a temperature coefficient of ±50ppm/°C, superior to both the original TL3AR005F (±75ppm/°C) and TLRP3A20WR005FTE (±100ppm/°C).

Q: Can I use a 2W-rated substitute in place of the 1W original part?

A: Yes. A higher power rating provides additional thermal margin and does not compromise circuit function. TLRP3A20WR005FTE and CSNL2512FT5L00 both provide 2W rating while maintaining identical resistance and tolerance specifications.

Q: What is the difference between metal foil and metal element composition?

A: Both compositions are suitable for current sense applications. The original TL3AR005F and its direct equivalent TL3AR005FTDG use metal foil construction. CSNL2512FT5L00 uses metal element construction with moisture-resistant features. Both maintain the specified electrical performance.
