TRR03EZPJ151 Equivalent & Substitute Parts

Part Overview

The TRR03EZPJ151 is a 150 Ohms ±5% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This thick film resistor features anti-sulfur composition and operates across -55°C to 155°C. The part is currently obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. Substitute parts maintain the same resistance value, package footprint, and power rating while offering improved specifications or active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the TRR03EZPJ151 is determined by strict equivalence in the following parameters:

• Resistance value: 150 Ohms (exact match required)
• Power rating: 0.1W minimum
• Package: 0603 (1608 Metric) footprint
• Composition: Thick film construction
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance and MSL 1 rating

Substitute parts are grouped into two categories:

Direct Equivalent (Tolerance Match): RMCS0603FT150R maintains the ±5% tolerance specification of the original part while offering improved temperature coefficient and active product status.

Upgrade Substitutes (Enhanced Tolerance): ERJ-S03J151V and ERJ-S03F1500V provide ±1% tolerance with automotive AEC-Q200 qualification, representing performance upgrades suitable for applications requiring tighter tolerance control or automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: RMCS0603FT150R is the primary substitute, offering identical tolerance specification (±5%) with active product status and improved temperature coefficient (±100ppm/°C vs ±200ppm/°C). This part maintains full electrical and mechanical compatibility with the TRR03EZPJ151.

For Upgraded Applications: ERJ-S03J151V provides ±5% tolerance with automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability. ERJ-S03F1500V offers ±1% tolerance with AEC-Q200 qualification for applications demanding tighter tolerance control and automotive compliance.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical package footprint, ensuring direct PCB compatibility without design modification.

Frequently Asked Questions (FAQ)

Q: Can RMCS0603FT150R be used as a direct replacement for TRR03EZPJ151? A: Yes. Both parts share identical resistance (150 Ohms), tolerance (±5%), power rating (0.1W), package (0603), composition (thick film), and operating temperature range (-55°C to 155°C). RMCS0603FT150R is active and offers improved temperature coefficient.

Q: What is the difference between the substitute parts? A: RMCS0603FT150R maintains ±5% tolerance matching the original. ERJ-S03J151V provides ±5% tolerance with AEC-Q200 automotive qualification. ERJ-S03F1500V offers ±1% tolerance with AEC-Q200 qualification. All three are electrically and mechanically compatible with the original part.

Q: Are the substitute parts compatible with existing PCB designs? A: Yes. All substitute parts use the identical 0603 (1608 Metric) package with matching footprint dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm) and height (0.022" maximum seated height). No PCB redesign is required.

Q: Do the substitute parts meet the same compliance requirements? A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original part's compliance profile.

Q: Which substitute should be selected for automotive applications? A: ERJ-S03J151V or ERJ-S03F1500V are recommended for automotive applications due to AEC-Q200 qualification. ERJ-S03F1500V provides additional tolerance improvement (±1%) if required by application specifications.
