Key Parameters

Substitute Part Grouping Explanation

Substitute parts for SR1206JR-072R4L are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 2.4 Ohms
• Power rating: 0.25W (1/4W)
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package type: 1206 (3216 Metric)
• Number of terminations: 2
• Composition: Thick Film

Tolerance Variations (Allowed):

• Tolerance may be ±1% or ±5% depending on application requirements

Compliance & Features (Considered):

• RoHS3 compliance required
• MSL 1 rating required
• AEC-Q200 automotive rating where specified

Substitutes are grouped by tolerance class and feature set to enable direct replacement or upgraded performance selection.

Parameter Comparison

Engineering Selection Recommendations

Direct Replacement (Same Tolerance, Same Features):

• RC1206JR-072R4L: YAGEO equivalent with identical ±5% tolerance and moisture resistant construction. Maintains AEC-Q200 compliance through RC_L series.
• CRCW12062R40JNEA: Vishay Dale alternative with ±5% tolerance and AEC-Q200 automotive rating. Cross-manufacturer option for supply chain diversification.

Upgraded Performance (Tighter Tolerance):

• AC1206FR-072R4L: YAGEO ±1% tolerance variant with automotive AEC-Q200 and moisture resistant features. Suitable for applications requiring improved accuracy.
• RC1206FR-072R4L: YAGEO ±1% tolerance variant with moisture resistant construction. Non-automotive rated but electrically equivalent for general applications.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical specifications (resistance, power, temperature coefficient, operating range) required for functional interchangeability.

Frequently Asked Questions (FAQ)

Q: Can RC1206JR-072R4L replace SR1206JR-072R4L directly? A: Yes. Both parts share identical electrical specifications (2.4Ω ±5%, 0.25W), temperature characteristics, and 1206 package. RC1206JR-072R4L adds moisture resistant construction as an enhancement.

Q: What is the difference between ±5% and ±1% tolerance variants? A: Tolerance defines the acceptable resistance deviation from the nominal 2.4 Ohm value. ±5% allows ±0.12Ω variation; ±1% allows ±0.024Ω variation. Select ±1% for precision-critical circuits; ±5% for general applications.

Q: Are all substitutes automotive-rated? A: SR1206JR-072R4L, AC1206FR-072R4L, and CRCW12062R40JNEA carry AEC-Q200 automotive certification. RC1206FR-072R4L and RC1206JR-072R4L do not specify automotive rating but meet equivalent electrical and environmental specifications.

Q: Can I use a non-YAGEO part (Vishay Dale CRCW12062R40JNEA)? A: Yes. CRCW12062R40JNEA matches all critical parameters: 2.4Ω ±5%, 0.25W, 1206 package, AEC-Q200 rating, and identical temperature characteristics. Cross-manufacturer substitution is valid for supply continuity.

Q: What does MSL 1 mean? A: Moisture Sensitivity Level 1 indicates unlimited shelf life without moisture control requirements. All listed parts carry MSL 1, ensuring no special storage or handling is necessary.

Q: Are package dimensions identical across all substitutes? A: Primary dimensions are equivalent (1206 / 3216 Metric). CRCW12062R40JNEA shows minor height variation (0.024" vs 0.026" max seated height), which is within standard PCB assembly tolerances and does not affect functionality.
