Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-B2CJR033V is determined by the following critical parameters:

• Resistance value: 33 mOhms (exact match required)
• Power rating: 1W (exact match required)
• Package format: Wide 1206 (3216 Metric), 0612 (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: 0/+200 ppm/°C (exact match required)
• Operating temperature range: -55°C to +155°C (exact match required)
• Automotive qualification: AEC-Q200 (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The ERJ-B2CFR033V qualifies as a direct substitute because it maintains all critical electrical and mechanical parameters while offering an improved tolerance specification of ±1% compared to the original ±5% tolerance.

Parameter Comparison

Engineering Selection Recommendations

Both the ERJ-B2CJR033V and ERJ-B2CFR033V are active production components from Panasonic Electronic Components with full AEC-Q200 automotive qualification and ROHS3 compliance. The ERJ-B2CFR033V offers superior tolerance performance at ±1% compared to the ±5% specification of the ERJ-B2CJR033V, while maintaining identical electrical characteristics, package dimensions, and thermal performance. Selection between these parts should be based on tolerance requirements for the specific application circuit and component availability constraints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-B2CFR033V replace ERJ-B2CJR033V in existing designs?

A: Yes. The ERJ-B2CFR033V is a direct substitute with identical resistance value, power rating, package format, temperature coefficient, and operating temperature range. The improved ±1% tolerance provides tighter resistance control compared to the original ±5% specification.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts use the Wide 1206 (3216 Metric) package format with identical dimensions of 0.063" L × 0.126" W (1.60mm × 3.20mm) and maximum seated height of 0.031" (0.80mm).

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ERJ-B2CJR033V and ERJ-B2CFR033V carry AEC-Q200 qualification and are suitable for automotive applications within the specified operating temperature range of -55°C to +155°C.

Q: What is the difference in tolerance between these parts?

A: The ERJ-B2CJR033V has ±5% tolerance while the ERJ-B2CFR033V has ±1% tolerance. Both maintain the same 0/+200 ppm/°C temperature coefficient and thick film composition.

Q: Are both parts RoHS compliant?

A: Yes. Both parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
