Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-2371-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 2.37 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: ±0.5% (main part) to ±0.1% (substitute parts) — tighter tolerance is acceptable
• Power Rating: 0.125W (main part) to 0.25W (substitute parts) — higher power rating is acceptable
• Automotive Rating: AEC-Q200 (main part) to unspecified (substitute parts) — presence of AEC-Q200 in substitutes is acceptable but not required

Substitute parts are grouped into two categories: direct equivalents matching all specifications, and upgrade substitutes offering improved tolerance or power rating while maintaining core electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Matching Specifications):

RT0805DRD072K37L (YAGEO) is a direct equivalent to the RG2012P-2371-D-T5. Both parts share identical resistance, tolerance, power rating, package, composition, and temperature characteristics. The RT0805DRD072K37L is active in production with 4750 units in stock, providing supply availability. This part is suitable for applications where the original Susumu part is unavailable or where YAGEO sourcing is preferred.

Upgrade Substitutes (Improved Tolerance):

ERA-6AEB2371V (Panasonic Electronic Components) and RT0805BRD072K37L (YAGEO) offer ±0.1% tolerance compared to the ±0.5% tolerance of the main part, while maintaining identical power rating, package, and operating temperature range. Both parts retain AEC-Q200 qualification (ERA-6AEB2371V) or are unspecified for automotive rating (RT0805BRD072K37L). These upgrades are suitable for applications requiring tighter resistance tolerance without changing circuit board layout or thermal characteristics.

Higher Power Rating Substitute:

4-2176092-9 (TE Connectivity Passive Product) provides 0.25W (1/4W) power rating with ±0.1% tolerance in the same 0805 package. The increased seated height (0.026" vs. 0.020" for the main part) must be evaluated for board clearance compatibility. This part is suitable for applications requiring higher power dissipation capability or tighter tolerance specifications.

All substitute parts are ROHS3 compliant with MSL 1 rating and operate across the -55°C ~ 155°C temperature range, ensuring compatibility with the original design requirements.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRD072K37L replace RG2012P-2371-D-T5 in automotive applications?

A: RT0805DRD072K37L is electrically and mechanically compatible with RG2012P-2371-D-T5. However, the main part carries AEC-Q200 automotive qualification while RT0805DRD072K37L does not specify this rating. For applications requiring AEC-Q200 compliance, ERA-6AEB2371V is the appropriate substitute.

Q: What is the difference between the main part and upgrade substitutes?

A: The main part RG2012P-2371-D-T5 has ±0.5% tolerance, while ERA-6AEB2371V and RT0805BRD072K37L offer ±0.1% tolerance. All three maintain identical 0.125W power rating and 0805 package. The tighter tolerance in upgrade substitutes provides improved resistance accuracy without affecting thermal or mechanical characteristics.

Q: Is 4-2176092-9 suitable for direct replacement?

A: 4-2176092-9 is mechanically compatible in the 0805 package but has a higher seated height (0.026" vs. 0.020"). The increased power rating (0.25W vs. 0.125W) and tighter tolerance (±0.1% vs. ±0.5%) make it suitable for applications requiring these specifications. Board clearance must be verified before substitution.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all substitute parts listed are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity level, matching the environmental compliance of the main part.

Q: What is the impact of tolerance differences on circuit performance?

A: The main part tolerance of ±0.5% allows resistance variation of ±0.01185 kOhms around the 2.37 kOhms nominal value. Upgrade substitutes with ±0.1% tolerance restrict variation to ±0.00237 kOhms. Selection depends on circuit requirements for precision and stability.

Q: Can substitute parts be mixed in the same design?

A: All substitute parts share the same 0805 package, operating temperature range, and composition. Mixing parts with different tolerances (±0.5% vs. ±0.1%) or power ratings (0.125W vs. 0.25W) is permissible if circuit design accommodates the tolerance stack-up and thermal requirements.
