Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-243-W-T5 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 24 kOhms
• Tolerance: ±0.05%
• Power rating: 0.125W (1/8W)
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All identified substitute parts meet these parameters without exception. Substitution is valid across manufacturers (Susumu and Panasonic Electronic Components) provided all electrical and mechanical specifications remain identical. Packaging format (Tape & Reel) is consistent across all parts.

Parameter Comparison

Engineering Selection Recommendations

RG2012N-243-W-T1 (Susumu): This part is a direct equivalent to the RG2012N-243-W-T5, differing only in tape reel configuration (T1 versus T5 designation). Both are manufactured by Susumu, carry identical electrical and mechanical specifications, and maintain full AEC-Q200 automotive qualification. The RG2012N-243-W-T1 offers higher inventory availability (5814 units) compared to the primary part number. Selection between these two Susumu variants is based on tape reel packaging requirements specific to assembly equipment compatibility.

ERA-6ARW243V (Panasonic Electronic Components): This Panasonic part provides cross-manufacturer equivalence with identical electrical performance and automotive qualification. All critical parameters match the primary part, including resistance, tolerance, power rating, temperature coefficient, and operating range. The ERA-6ARW243V exhibits a maximum seated height of 0.024" (0.60mm) compared to 0.020" (0.50mm) for the Susumu variants. This 0.004" (0.10mm) height difference must be evaluated for PCB layout clearance in space-constrained applications. The Panasonic part maintains ROHS3 compliance and MSL 1 rating. Inventory availability is 4290 units.

All three parts are active products with current production status and full regulatory compliance documentation.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-243-W-T1 be used as a direct replacement for RG2012N-243-W-T5?

A: Yes. Both parts are manufactured by Susumu with identical electrical specifications, power rating, package dimensions, and automotive qualification. The T1 and T5 designations refer to tape reel configuration only. Substitution is valid provided assembly equipment is compatible with the specified tape format.

Q: What is the difference between Susumu RG series and Panasonic ERA-6A series parts?

A: Both manufacturers produce thin film 0805 chip resistors with identical electrical performance for this 24 kOhm ±0.05% specification. The primary difference is seated height: Susumu parts measure 0.020" (0.50mm) maximum, while the Panasonic ERA-6ARW243V measures 0.024" (0.60mm) maximum. This 0.004" difference must be considered for PCB layout and component clearance verification.

Q: Are all three parts AEC-Q200 qualified?

A: Yes. RG2012N-243-W-T5, RG2012N-243-W-T1, and ERA-6ARW243V all carry AEC-Q200 automotive qualification, suitable for automotive and high-reliability applications.

Q: What is the significance of the ±0.05% tolerance specification?

A: The ±0.05% tolerance indicates precision thin film construction with tight resistance value control. This specification is maintained across all three substitute parts, ensuring equivalent performance in precision analog circuits, measurement instrumentation, and applications requiring stable reference resistances.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. All three parts operate across the identical temperature range of -55°C to 155°C with ±10ppm/°C temperature coefficient. Thermal performance is equivalent across all substitutes.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 indicates the lowest moisture sensitivity level. These parts require no special moisture control during storage, handling, or assembly, providing maximum flexibility in manufacturing environments.

Q: Are all parts RoHS3 compliant?

A: Yes. RG2012N-243-W-T5, RG2012N-243-W-T1, and ERA-6ARW243V are all ROHS3 compliant, meeting current environmental and regulatory requirements for electronic components.
