Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S1TJ151U is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 150 Ohms
• Tolerance: ±5%
• Power rating: 1W (or higher)
• Package: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C or better
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance

Secondary Considerations:

• AEC-Q200 automotive rating (preferred for automotive applications)
• Physical dimensions within acceptable PCB footprint tolerances
• Moisture sensitivity level MSL 1

Parts are grouped into three categories based on their relationship to the main part:

1. Similar Manufacturer Parts – Alternative part numbers from the same or different manufacturers that meet all primary matching parameters
2. Direct Manufacturer Parts – Parts from other manufacturers with identical electrical specifications
3. Enhanced Specification Parts – Parts with superior power ratings or additional features that maintain backward compatibility

Parameter Comparison

Engineering Selection Recommendations

Preferred Substitutes for Automotive Applications:

For designs requiring AEC-Q200 compliance and active product status, the following parts are direct substitutes:

• RMCF2512JT150R (Stackpole Electronics Inc) – Identical specifications, active status, 12,122 units available
• CRCW2512150RJNEG (Vishay Dale) – Identical specifications, active status, 3,100 units available
• SR2512JK-07150RL (YAGEO) – Identical specifications with superior temperature coefficient (±100ppm/°C), active status, 7,200 units available

Alternative for Non-Automotive Applications:

CR2512-JW-151ELF (Bourns Inc.) meets all electrical specifications and operates across the full temperature range, though it lacks AEC-Q200 rating. This part is suitable for non-automotive applications requiring identical electrical performance.

Enhanced Specification Option:

CRCW2512150RJNEGHP (Vishay Dale) provides 1.5W power rating with pulse withstanding capability while maintaining all other specifications. This part is suitable for applications requiring higher power dissipation margin.

Legacy Part:

ERJ-1TYJ151U (Panasonic Electronic Components) is marked "Not For New Designs" and should not be selected for new product development, despite high inventory availability.

Temperature Range Consideration:

3520150RJT (TE Connectivity) operates to -55°C ~ 125°C, which is 30°C below the ERJ-S1TJ151U upper limit. This part is suitable only for applications not requiring the full 155°C operating temperature.

Frequently Asked Questions (FAQ)

Q: Can I use ERJ-1TYJ151U as a substitute for ERJ-S1TJ151U?

A: ERJ-1TYJ151U meets all electrical and mechanical specifications. However, it is marked "Not For New Designs" by the manufacturer. Use only in legacy product support or when ERJ-S1TJ151U is unavailable and design refresh is not feasible.

Q: What is the difference between CRCW2512150RJNEG and CRCW2512150RJNEGHP?

A: Both parts are 150 Ohm ±5% in 2512 package with AEC-Q200 rating. CRCW2512150RJNEGHP has a 1.5W power rating and pulse withstanding capability compared to 1W for CRCW2512150RJNEG. CRCW2512150RJNEGHP is suitable for applications requiring higher power dissipation.

Q: Is CR2512-JW-151ELF suitable for automotive applications?

A: CR2512-JW-151ELF meets all electrical specifications but lacks AEC-Q200 automotive certification. It is suitable for non-automotive applications. For automotive designs, use RMCF2512JT150R, CRCW2512150RJNEG, or SR2512JK-07150RL.

Q: Why does 3520150RJT have a lower maximum operating temperature?

A: 3520150RJT operates to 125°C maximum, which is 30°C below the ERJ-S1TJ151U specification of 155°C. This part is suitable only for applications not requiring operation above 125°C.

Q: Does SR2512JK-07150RL have better temperature stability?

A: SR2512JK-07150RL has a temperature coefficient of ±100ppm/°C compared to ±200ppm/°C for ERJ-S1TJ151U. This provides superior temperature stability and is suitable for precision applications requiring tighter tolerance over temperature.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts are RoHS3 compliant and have MSL 1 (Unlimited) moisture sensitivity rating, matching the ERJ-S1TJ151U specifications.

Q: Can I interchange these parts on the same PCB without layout changes?

A: All parts use the 2512 (6432 Metric) package with identical footprint requirements. Physical dimensions vary slightly (length 6.30–6.40mm, width 3.10–3.20mm, height 0.65–0.75mm), but these variations are within standard PCB design tolerances for 2512 package placement.
