Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-1TYJ2R7U is determined by the following critical parameters: resistance value (2.7 Ohms), tolerance specification (±5%), power dissipation capability (1W minimum), package footprint compatibility (2512 or equivalent metric dimensions), composition type (thick film), and automotive qualification (AEC-Q200). Substitute parts must maintain these core electrical and mechanical characteristics to ensure functional equivalence in circuit applications.

The identified substitute parts are grouped into two categories:

Direct Equivalents (Same Package, Same Power Rating): Parts maintaining identical 2512 package and 1W power rating with matching or improved tolerance specifications.

Functional Alternatives (Different Package or Power Rating): Parts with different physical dimensions or higher power ratings that may require board layout modification but provide electrical equivalence.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Footprint and Power Rating):

ERJ-1TRQJ2R7U and ERJ-1TRQF2R7U are both available in the 2512 package with 1W power rating and maintain full AEC-Q200 automotive qualification. ERJ-1TRQJ2R7U preserves the ±5% tolerance specification of the original part and carries Active product status. ERJ-1TRQF2R7U offers improved tolerance at ±1% while maintaining the same package and power rating, also with Active product status.

For Higher Power Dissipation Applications:

RHC2512FT2R70 from Stackpole Electronics provides 2W power rating in the same 2512 package with ±1% tolerance and Active product status. This part does not carry explicit AEC-Q200 designation but includes moisture-resistant thick film construction. ERJ-B1BJ2R7U from Panasonic offers 2W power rating with AEC-Q200 qualification; however, it uses a Wide 2010 (5025 Metric) package requiring board layout modification.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Parts with Active product status are suitable for new design implementations, whereas the original ERJ-1TYJ2R7U is restricted from new designs.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TRQJ2R7U be used as a direct replacement for ERJ-1TYJ2R7U?

A: Yes. Both parts share identical electrical specifications (2.7 Ohms ±5%, 1W), the same 2512 package footprint, and AEC-Q200 automotive qualification. ERJ-1TRQJ2R7U has Active product status, making it suitable for new applications.

Q: What is the difference between ERJ-1TRQJ2R7U and ERJ-1TRQF2R7U?

A: Both parts maintain the 2512 package and 1W power rating. The primary difference is tolerance: ERJ-1TRQJ2R7U is ±5%, while ERJ-1TRQF2R7U is ±1%. ERJ-1TRQF2R7U also features a lower temperature coefficient (±100ppm/°C versus ±100ppm/°C for the main part).

Q: Can ERJ-B1BJ2R7U replace ERJ-1TYJ2R7U without board redesign?

A: No. ERJ-B1BJ2R7U uses a Wide 2010 (5025 Metric) package, which has different footprint dimensions than the 2512 package. Board layout modification is required. However, it provides 2W power rating and maintains AEC-Q200 qualification.

Q: Is RHC2512FT2R70 suitable for automotive applications?

A: RHC2512FT2R70 maintains the 2512 package and provides 2W power rating with ±1% tolerance. It does not carry explicit AEC-Q200 designation. Selection depends on specific automotive qualification requirements of the application.

Q: What are the key parameters that determine substitution compatibility?

A: Resistance value (2.7 Ohms), tolerance specification, power rating (minimum 1W), package footprint (2512 preferred for direct replacement), composition (thick film), and operating temperature range (-55°C ~ 155°C) are the primary determinants. Automotive qualification (AEC-Q200) is required for automotive applications.
