ERJ-S02J5R1X Equivalent & Substitute Parts

Part Overview

The ERJ-S02J5R1X is a 5.1 Ohm thick film chip resistor manufactured by Panasonic Electronic Components in the 0402 (1005 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation with ±5% tolerance and features anti-sulfur coating with AEC-Q200 automotive qualification. The part is currently in active production status with 1031 pieces available in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required but alternative packaging, series designations, or inventory considerations necessitate component alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the ERJ-S02J5R1X is based on electrical and mechanical parameter equivalence. The following criteria determine valid substitutes:

Electrical Parameters:

• Resistance value: 5.1 Ohms
• Tolerance: ±5%
• Power rating: 0.1W (1/10W)
• Temperature coefficient: -100 / +600 ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package format: 0402 (1005 Metric)
• Number of terminations: 2
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Maximum seated height: 0.016" (0.40mm)

Compliance & Certification:

• Composition: Thick Film
• Features: Anti-Sulfur, Automotive AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Substitute parts must match all electrical parameters, mechanical dimensions, and compliance certifications. Variations in manufacturer series designation or packaging format (tape & reel versus bulk) do not affect functional equivalence when all specified parameters are identical.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-U02J5R1X is a direct functional equivalent to the ERJ-S02J5R1X. Both components are manufactured by Panasonic Electronic Components and share identical electrical specifications, mechanical dimensions, and compliance certifications. The primary difference between these parts is the packaging format: the ERJ-S02J5R1X is supplied in bulk packaging, while the ERJ-U02J5R1X is supplied in tape & reel (TR) format.

Both parts maintain active production status and are ROHS3 compliant with AEC-Q200 automotive qualification. The identical temperature coefficient (-100 / +600 ppm/°C), operating temperature range (-55°C ~ 155°C), and moisture sensitivity level (MSL 1) ensure equivalent performance in automotive and industrial applications.

Selection between these parts should be based on procurement and assembly requirements. Bulk packaging is suitable for manual assembly or small-volume applications, while tape & reel packaging is optimized for automated pick-and-place assembly processes. The ERJ-U02J5R1X offers higher inventory availability (6860 pieces) compared to the ERJ-S02J5R1X (1031 pieces), which may influence lead time considerations.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-U02J5R1X be used as a direct replacement for the ERJ-S02J5R1X?

A: Yes. The ERJ-U02J5R1X is electrically and mechanically equivalent to the ERJ-S02J5R1X. Both components have identical resistance (5.1 Ohms), tolerance (±5%), power rating (0.1W), package format (0402), and compliance certifications (AEC-Q200, ROHS3). The only difference is the packaging format (tape & reel versus bulk).

Q: What is the difference between the ERJ-S02 and ERJ-U02 series?

A: The ERJ-S02 and ERJ-U02 series are both Panasonic thick film chip resistor lines with identical electrical and mechanical specifications. The series designation reflects different packaging configurations. The ERJ-S02 series is supplied in bulk format, while the ERJ-U02 series is supplied in tape & reel format for automated assembly.

Q: Are both parts suitable for automotive applications?

A: Yes. Both the ERJ-S02J5R1X and ERJ-U02J5R1X carry AEC-Q200 automotive qualification and anti-sulfur coating, making them suitable for automotive and harsh environment applications. Both parts operate across the -55°C ~ 155°C temperature range required for automotive use.

Q: What does the 0402 package designation mean?

A: The 0402 package designation refers to the metric 1005 format, indicating component dimensions of 1.00mm length by 0.50mm width. Both substitute parts use this identical package format with a maximum seated height of 0.016" (0.40mm).

Q: Which part should be selected for automated assembly?

A: The ERJ-U02J5R1X is supplied in tape & reel (TR) packaging, which is optimized for automated pick-and-place assembly equipment. The ERJ-S02J5R1X is supplied in bulk packaging, which is suitable for manual assembly or lower-volume applications.

Q: Are there any compliance or certification differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity level (MSL 1) ratings. Both components meet AEC-Q200 automotive standards and feature anti-sulfur coating for enhanced reliability in corrosive environments.
