Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S02J123X are qualified based on strict electrical and mechanical parameter matching:

Electrical Parameters (Must Match):

• Resistance value: 12 kOhms
• Tolerance: ±5%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package / Case: 0402 (1005 Metric)
• Number of terminations: 2
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Height - Seated (Max): 0.016" (0.40mm)

Compliance & Certification (Must Match):

• Automotive AEC-Q200 qualification
• ROHS3 compliance
• Moisture Sensitivity Level 1

Substitute parts are grouped into two categories: Direct Manufacturer Substitutes (same manufacturer, different series) and Similar Manufacturer Parts (same manufacturer, alternative packaging). All substitutes maintain identical electrical performance and physical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ERJ-S02J123X, ERJ-U02J123X, and ERJ-2GEJ123X—are functionally equivalent for applications requiring a 12 kOhms ±5% 0.1W thick film resistor in 0402 package format. Selection between these parts should be based on the following criteria:

Direct Manufacturer Substitute (ERJ-U02J123X): This part maintains identical electrical specifications and Tape & Reel packaging as the primary part. It is suitable for applications where packaging consistency with the ERJ-S02 series is preferred. Higher inventory availability (20209 units) supports procurement flexibility.

Similar Manufacturer Part (ERJ-2GEJ123X): This part offers the same electrical and mechanical specifications but is supplied in Cut Tape (CT) and Digi-Reel® packaging format. It is appropriate for applications where alternative packaging formats are acceptable. Significantly higher inventory availability (363653 units) provides extended supply chain security.

All parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL Level 1 rating, confirming suitability for automotive and high-reliability industrial applications across the full operating temperature range of -55°C to 155°C.

Frequently Asked Questions (FAQ)

Q: Can ERJ-U02J123X be used as a direct replacement for ERJ-S02J123X?

A: Yes. Both parts share identical electrical specifications (12 kOhms ±5%, 0.1W, ±200ppm/°C, -55°C ~ 155°C), mechanical dimensions (0402 package, 1.00mm x 0.50mm), and automotive AEC-Q200 qualification. The primary difference is the product series designation (ERJ-U02 vs. ERJ-S02). Both are supplied in Tape & Reel packaging.

Q: What is the difference between ERJ-2GEJ123X and the other two parts?

A: ERJ-2GEJ123X is electrically and mechanically identical to ERJ-S02J123X and ERJ-U02J123X. The key difference is packaging format: ERJ-2GEJ123X is supplied in Cut Tape (CT) and Digi-Reel® format, while the other two use standard Tape & Reel (TR) packaging. All other specifications, including resistance, tolerance, power rating, temperature range, and AEC-Q200 rating, are identical.

Q: Are these parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are rated for the full automotive temperature range of -55°C to 155°C. They are ROHS3 compliant and have MSL Level 1 rating, confirming suitability for automotive and high-reliability industrial environments.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tape & Reel vs. Cut Tape & Digi-Reel) affects only handling, storage, and procurement logistics. Electrical and mechanical specifications remain identical across all three parts.

Q: Which part should be selected for maximum supply chain availability?

A: ERJ-2GEJ123X offers the highest inventory availability at 363653 units, followed by ERJ-U02J123X at 20209 units. Selection should align with packaging requirements and procurement lead time constraints.
