Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-273-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27 kOhms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive rating: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Variable Parameters Allowing Substitution:

• Tolerance: Substitute parts may offer equal or tighter tolerance specifications (±0.5%, ±0.1%, ±0.05%)
• Manufacturer: Susumu or Panasonic Electronic Components
• Physical height: Maximum seated height up to 0.024" (0.60mm) is acceptable

All identified substitutes maintain identical electrical performance characteristics and mechanical compatibility while offering alternative sourcing options or enhanced tolerance specifications.

Parameter Comparison

Engineering Selection Recommendations

RG2012N-273-W-T1 (Susumu)

This part is a direct upgrade within the Susumu RG series, offering tighter tolerance specification (±0.05% versus ±0.5%) while maintaining all other electrical and mechanical parameters. Both parts share identical package dimensions, power rating, temperature coefficient, and automotive AEC-Q200 qualification. Selection of RG2012N-273-W-T1 is appropriate when circuit design requires improved tolerance performance without changing supplier or package footprint.

ERA-6ARB273V (Panasonic Electronic Components)

This Panasonic substitute provides ±0.1% tolerance with full AEC-Q200 automotive qualification and identical electrical specifications. The maximum seated height increases to 0.024" (0.60mm) compared to 0.020" (0.50mm) for the primary part. Selection is appropriate for applications where Panasonic sourcing is preferred and the additional 0.004" height clearance is available on the PCB assembly.

ERA-6ARW273V (Panasonic Electronic Components)

This Panasonic substitute offers the tightest tolerance specification (±0.05%) among all identified alternatives, with full AEC-Q200 automotive qualification. Maximum seated height is 0.024" (0.60mm). Selection is appropriate for high-precision circuit applications requiring Panasonic sourcing and where the increased component height is accommodated in the design.

All substitute parts maintain active product status, ROHS3 compliance, and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-273-W-T1 be used as a direct replacement for RG2012N-273-D-T5?

A: Yes. Both parts are manufactured by Susumu in the RG series with identical 27 kOhms resistance, 0805 package, 0.125W power rating, ±10ppm/°C temperature coefficient, and -55°C to 155°C operating range. RG2012N-273-W-T1 offers improved tolerance (±0.05% versus ±0.5%) with no change to package footprint or mechanical dimensions.

Q: What is the difference between Susumu and Panasonic substitutes?

A: Both manufacturers provide AEC-Q200 qualified thin film 27 kOhms resistors in 0805 package with identical electrical performance. Panasonic parts (ERA-6ARB273V and ERA-6ARW273V) have a maximum seated height of 0.024" (0.60mm) compared to 0.020" (0.50mm) for Susumu parts. Tolerance specifications vary: ERA-6ARB273V offers ±0.1%, while ERA-6ARW273V offers ±0.05%.

Q: Are there any PCB layout considerations when substituting with Panasonic parts?

A: Panasonic ERA-6A series parts have a maximum seated height of 0.024" (0.60mm), which is 0.004" taller than the Susumu RG2012N series at 0.020" (0.50mm). Verify that PCB assembly clearance accommodates this height difference, particularly in applications with tight vertical spacing constraints.

Q: Do all substitute parts maintain automotive AEC-Q200 qualification?

A: Yes. All identified substitutes—RG2012N-273-W-T1, ERA-6ARB273V, and ERA-6ARW273V—carry full AEC-Q200 automotive qualification, identical to the primary part RG2012N-273-D-T5.

Q: What tolerance should I select for my application?

A: Tolerance selection depends on circuit requirements. The primary part RG2012N-273-D-T5 provides ±0.5% tolerance. RG2012N-273-W-T1 and ERA-6ARW273V both offer ±0.05% for precision applications. ERA-6ARB273V provides intermediate ±0.1% tolerance. All tolerances are compatible with the specified temperature coefficient and operating range.

Q: Are all parts ROHS3 compliant?

A: Yes. RG2012N-273-D-T5, RG2012N-273-W-T1, ERA-6ARB273V, and ERA-6ARW273V are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Q: Can I mix different manufacturers in the same PCB assembly?

A: Yes. All identified parts maintain identical electrical specifications, package configuration, and automotive qualification. Mixed sourcing from Susumu and Panasonic is permissible from an engineering compatibility standpoint, though procurement and quality control procedures should address any internal sourcing requirements.
