Substitute Part Grouping Explanation

Substitution of the RG2012N-302-W-T5 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 3 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Temperature coefficient: ±10ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)

Compliance & Certification:

• Automotive AEC-Q200 qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory conformance)
• Moisture Sensitivity Level 1 (required for handling and storage compatibility)

Substitute parts must satisfy all electrical, mechanical, and compliance parameters without deviation. Packaging format (Tape & Reel) is consistent across all qualified alternatives.

Parameter Comparison

Engineering Selection Recommendations

RG2012N-302-W-T1 (Susumu): This part is a direct equivalent to the RG2012N-302-W-T5, manufactured by the same supplier (Susumu) within the same RG series. All electrical, mechanical, and compliance parameters are identical. The primary distinction is the tape reel specification (T1 versus T5), which reflects different reel configurations for the same component. This substitute is suitable for direct replacement in all applications where the RG2012N-302-W-T5 is specified. Current inventory of 4533 units provides enhanced availability.

ERA-6ARW302V (Panasonic Electronic Components): This part meets all critical electrical and compliance requirements and is qualified to AEC-Q200 automotive standards. The component is manufactured by Panasonic within the ERA-6A series. All electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating range) are identical to the primary part. The seated height specification is 0.024" (0.60mm) compared to 0.020" (0.50mm) for the Susumu parts, representing a 0.004" (0.10mm) difference. This height variance is within typical PCB design tolerances for 0805 package components and does not affect electrical performance or mechanical fit in standard applications. Current inventory of 12412 units provides significant supply availability. This substitute is suitable for applications where cross-manufacturer sourcing is acceptable and where the minor height difference does not create design constraints.

Both substitute parts carry active product status and full compliance certifications (RoHS3, AEC-Q200, MSL 1).

Frequently Asked Questions (FAQ)

Q: Can RG2012N-302-W-T1 be used as a direct replacement for RG2012N-302-W-T5?

A: Yes. Both parts are manufactured by Susumu and share identical electrical specifications (3 kOhms, ±0.05%, 0.125W, ±10ppm/°C, -55°C ~ 155°C), composition (thin film), package (0805), and compliance ratings (AEC-Q200, RoHS3, MSL 1). The difference between T1 and T5 designations refers to reel configuration only and does not affect component performance or compatibility.

Q: What is the significance of the height difference between Susumu and Panasonic parts?

A: The Susumu parts (RG2012N-302-W-T5 and RG2012N-302-W-T1) have a maximum seated height of 0.020" (0.50mm), while the Panasonic ERA-6ARW302V has a maximum seated height of 0.024" (0.60mm). This 0.004" (0.10mm) difference is within standard PCB design tolerances for 0805 package components and does not affect electrical performance, mechanical fit, or reflow soldering processes in typical applications.

Q: Are all three parts suitable for automotive applications?

A: Yes. All three parts carry AEC-Q200 automotive qualification and are rated for the same operating temperature range (-55°C ~ 155°C). They are suitable for automotive-grade applications requiring high reliability and temperature stability.

Q: What is the difference between T1 and T5 reel specifications?

A: T1 and T5 designations refer to different tape and reel configurations used for component packaging and automated assembly. Both configurations contain the same electrical component and are compatible with standard pick-and-place equipment. Selection between T1 and T5 depends on assembly line equipment compatibility and inventory management preferences.

Q: Can ERA-6ARW302V be used in applications where RG2012N-302-W-T5 is specified?

A: Yes, provided the 0.004" (0.10mm) height difference does not create design constraints. The ERA-6ARW302V meets all electrical, mechanical, and compliance requirements. Verification of PCB clearance and component placement constraints is necessary for applications with tight vertical spacing or specific design requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All three parts (RG2012N-302-W-T5, RG2012N-302-W-T1, and ERA-6ARW302V) are RoHS3 compliant and carry Moisture Sensitivity Level 1 (unlimited shelf life).

Q: What inventory levels are available for each part?

A: RG2012N-302-W-T5 has 1047 units in stock, RG2012N-302-W-T1 has 4533 units in stock, and ERA-6ARW302V has 12412 units in stock. Inventory levels support procurement planning and supply chain continuity.
