Key Parameters

Substitute Part Grouping Explanation

Substitution for the CSRN2512JTR330 is determined by the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 330 mOhms
• Power rating: 2W
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2

Allowable Variations:

• Tolerance: ±5% or tighter (±1%)
• Manufacturer: Different manufacturers permitted
• Specific features: Automotive AEC-Q200 qualification optional for non-automotive applications

Identified Substitute Categories:

1. Direct Equivalent (Same Tolerance): RLP73K3AR33JTE (TE Connectivity) — identical electrical and mechanical specifications with ±5% tolerance
2. Upgraded Tolerance (Tighter Tolerance): CSRN2512FKR330 (Stackpole) and RLP73K3AR33FTDF (TE Connectivity) — same base specifications with ±1% tolerance for improved precision

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Tolerance): RLP73K3AR33JTE from TE Connectivity Passive Product is a direct equivalent to CSRN2512JTR330. Both parts maintain ±5% tolerance, identical electrical performance, and full ROHS3 compliance. The primary difference is manufacturer origin and slightly increased seated height (0.033" vs 0.028"). This part is suitable for applications where tolerance and performance specifications are equivalent to the original design.

For Upgraded Precision (Tighter Tolerance): CSRN2512FKR330 (Stackpole) and RLP73K3AR33FTDF (TE Connectivity) both offer ±1% tolerance while maintaining all other electrical and mechanical specifications. These parts are suitable for applications requiring improved accuracy over the original ±5% specification. Both remain ROHS3 compliant and active in production.

Compliance Considerations: All substitute parts maintain ROHS3 compliance, MSL Level 1 (Unlimited), and REACH Unaffected status. The CSRN2512FKR330 and RLP73K3AR33JTE retain automotive AEC-Q200 qualification where applicable. Selection should be based on tolerance requirements, manufacturer preference, and availability.

Frequently Asked Questions (FAQ)

Q: Can RLP73K3AR33JTE be used as a direct replacement for CSRN2512JTR330? A: Yes. Both parts share identical resistance (330 mOhms), tolerance (±5%), power rating (2W), package (2512), composition (thick film), and operating temperature range (-55°C ~ 155°C). The seated height difference (0.033" vs 0.028") must be evaluated for PCB clearance in space-constrained layouts.

Q: What is the difference between the ±5% and ±1% tolerance versions? A: The ±1% tolerance versions (CSRN2512FKR330 and RLP73K3AR33FTDF) provide tighter resistance accuracy compared to the ±5% versions. All other electrical and mechanical parameters remain identical. Selection depends on circuit accuracy requirements.

Q: Are all substitute parts automotive qualified? A: CSRN2512JTR330 and CSRN2512FKR330 carry AEC-Q200 qualification. RLP73K3AR33JTE and RLP73K3AR33FTDF are current sense thick film resistors without specified automotive qualification in the provided data. Automotive application requirements should be confirmed with the manufacturer.

Q: Do the substitute parts have the same package dimensions? A: All parts use the 2512 (6432 Metric) package with identical length (0.250" / 6.35mm) and width (0.124" / 3.15mm). Stackpole parts have a maximum seated height of 0.028" (0.70mm), while TE Connectivity parts have 0.033" (0.84mm). PCB layout clearance must be verified for the TE Connectivity variants.

Q: Are all parts RoHS compliant? A: Yes. All parts listed are ROHS3 compliant with MSL Level 1 (Unlimited) and REACH Unaffected status.
