RG2012P-1020-D-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-1020-D-T5 is a 102 Ohm ±0.5% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation and features anti-sulfur coating with automotive AEC-Q200 qualification. The part is actively produced and maintained in inventory. Equivalent and substitute parts are identified when design requirements permit tolerance upgrades, power rating increases, or manufacturer alternatives while maintaining core electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the RG2012P-1020-D-T5 is determined by the following criteria:

Tolerance Upgrade Substitutes: Parts with ±0.1% tolerance are direct upgrades to the ±0.5% specification. These maintain identical resistance value, package, power rating, temperature coefficient, and operating temperature range while providing tighter tolerance performance.

Power Rating Upgrade Substitutes: Parts with 0.25W (1/4W) power rating are compatible when circuit design permits higher power dissipation capability. These maintain identical resistance value, tolerance, package, temperature coefficient, and operating temperature range.

Manufacturer Alternatives: Parts from different manufacturers (TE Connectivity, Panasonic) are substitutable when they match the core electrical parameters (102 Ohms, ±0.1% tolerance, 0.125W power rating, 0805 package, ±25ppm/°C temperature coefficient, -55°C ~ 155°C operating range) and maintain equivalent mechanical compatibility.

Key Substitution Parameters:

• Resistance value (102 Ohms)
• Package format (0805 / 2012 Metric)
• Temperature coefficient (±25ppm/°C)
• Operating temperature range (-55°C ~ 155°C)
• Composition (Thin Film)
• Tolerance (equal or tighter)
• Power rating (equal or higher)

Parameter Comparison

Engineering Selection Recommendations

RG2012P-1020-B-T5 (Susumu): This part is a direct upgrade substitute with tighter ±0.1% tolerance while maintaining identical power rating, package, and AEC-Q200 automotive qualification. Selection is appropriate when circuit design requires improved tolerance performance without changing any other electrical or mechanical characteristics. Both parts are actively produced with established inventory availability.

ERA-6AEB1020V (Panasonic): This part provides ±0.1% tolerance upgrade with equivalent power rating and AEC-Q200 automotive qualification. It is suitable for applications requiring manufacturer diversification or when Panasonic supply chain is preferred. Seated height is 0.024" (0.60mm), which is within acceptable PCB assembly tolerances compared to the original 0.020" (0.50mm).

2-2176091-5 (TE Connectivity): This part offers both tolerance upgrade (±0.1%) and power rating increase (0.25W). Selection is appropriate for designs requiring higher power dissipation margin or when TE Connectivity supply chain is mandated. Note that this part does not carry AEC-Q200 automotive qualification and has increased seated height of 0.026" (0.65mm). Use only in non-automotive applications or when automotive qualification is not required.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-1020-B-T5 be used as a direct replacement for RG2012P-1020-D-T5?

A: Yes. Both parts are manufactured by Susumu, share identical 102 Ohm resistance, 0.125W power rating, 0805 package, ±25ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The RG2012P-1020-B-T5 provides tighter ±0.1% tolerance compared to ±0.5%, making it a performance upgrade. Both maintain AEC-Q200 automotive qualification and ROHS3 compliance.

Q: What is the difference between the 0.125W and 0.25W power ratings?

A: Power rating indicates maximum continuous power dissipation capability. The 2-2176091-5 with 0.25W rating can dissipate twice the power of the 0.125W parts. Selection depends on circuit current and resistance calculations. Higher power rating provides design margin but does not affect electrical performance at equivalent power levels.

Q: Are there height differences between these substitutes?

A: Yes. The RG2012P-1020-D-T5 and RG2012P-1020-B-T5 have maximum seated height of 0.020" (0.50mm). The ERA-6AEB1020V is 0.024" (0.60mm), and the 2-2176091-5 is 0.026" (0.65mm). These differences are within standard PCB assembly tolerances but should be verified for applications with tight vertical clearance constraints.

Q: Why does 2-2176091-5 lack AEC-Q200 qualification?

A: AEC-Q200 is an automotive qualification standard. The 2-2176091-5 from TE Connectivity does not carry this certification. Use this part only in non-automotive applications or when automotive qualification is not a design requirement.

Q: Can these parts be used interchangeably in automotive applications?

A: RG2012P-1020-D-T5, RG2012P-1020-B-T5, and ERA-6AEB1020V all carry AEC-Q200 qualification and are suitable for automotive applications. The 2-2176091-5 does not have AEC-Q200 certification and should not be used in automotive designs requiring this qualification.

Q: What does ±0.5% versus ±0.1% tolerance mean for circuit performance?

A: Tolerance specifies the maximum deviation from the nominal 102 Ohm value. ±0.5% allows deviation up to ±0.51 Ohms (range: 101.49 to 102.51 Ohms). ±0.1% allows deviation up to ±0.102 Ohms (range: 101.898 to 102.102 Ohms). Tighter tolerance is beneficial for precision circuits but not necessary for general applications.

Q: Are all these parts ROHS3 compliant?

A: Yes. All four parts (RG2012P-1020-D-T5, RG2012P-1020-B-T5, 2-2176091-5, and ERA-6AEB1020V) are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture handling requirements.
