Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012V-7871-C-T5 is determined by strict equivalence in the following parameters:

Mandatory Equivalence Parameters:

• Resistance value: 7.87 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±5ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive rating: AEC-Q200
• Anti-sulfur construction

Allowable Variation Parameter:

• Tolerance: Substitute parts may have equal or tighter (lower) tolerance values than the original ±0.25% specification

All four substitute parts maintain identical resistance, package, power rating, composition, temperature characteristics, and automotive qualification. The substitutes differ only in tolerance specification, with values ranging from ±0.25% down to ±0.02%, representing performance upgrades rather than functional changes.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution Criteria:

All four substitute parts are electrically and mechanically compatible with the RG2012V-7871-C-T5. Selection among substitutes is based on tolerance requirements and product availability:

RG2012V-7871-B-T5 (±0.1% tolerance): Provides tighter tolerance specification than the original part while maintaining all other electrical and mechanical parameters. Suitable for applications requiring improved accuracy over the original ±0.25% specification. Product status is active with 734 units in stock.

RG2012V-7871-P-T1 (±0.02% tolerance): Offers the tightest tolerance specification among all substitutes, providing maximum accuracy for precision circuit applications. Product status is active with 961 units in stock. This part represents the highest performance option.

RG2012V-7871-W-T1 (±0.05% tolerance): Provides intermediate tolerance specification between the original and highest-precision options. Product status is active with 1154 units in stock, representing the highest inventory availability.

RG2012V-7871-W-T5 (±0.05% tolerance): Functionally equivalent to RG2012V-7871-W-T1 with identical tolerance and electrical specifications. Product status is active with 779 units in stock.

All substitutes maintain AEC-Q200 automotive qualification, ROHS3 compliance, and anti-sulfur construction. Selection should prioritize active product status and required tolerance specification for the target application.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-7871-C-T5 be directly replaced with any of the substitute parts?

A: Yes. All four substitute parts are direct replacements. They maintain identical resistance value (7.87 kOhms), package (0805), power rating (0.125W), composition (thin film), temperature coefficient (±5ppm/°C), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The only difference is tolerance specification, which is equal or tighter in all substitutes.

Q: What is the difference between the substitute parts?

A: The substitute parts differ only in tolerance specification. RG2012V-7871-B-T5 offers ±0.1% tolerance, RG2012V-7871-P-T1 offers ±0.02% tolerance, and both RG2012V-7871-W-T1 and RG2012V-7871-W-T5 offer ±0.05% tolerance. All other electrical and mechanical parameters are identical.

Q: Why are there two parts with ±0.05% tolerance (RG2012V-7871-W-T1 and RG2012V-7871-W-T5)?

A: Both parts have identical electrical specifications and tolerance. The difference is in the packaging designation (T1 versus T5), which relates to tape and reel specifications. Both are functionally equivalent for circuit applications.

Q: Is the original RG2012V-7871-C-T5 still available?

A: The original part is classified as obsolete. However, 876 units are currently in stock. For new designs or long-term production, selection of an active substitute part is recommended to ensure continued availability.

Q: Which substitute should I select if tolerance is not a critical parameter?

A: If tolerance is not critical, RG2012V-7871-W-T1 is recommended due to its highest inventory availability (1154 units in stock) and active product status. It provides ±0.05% tolerance, which is tighter than the original ±0.25% specification.

Q: Are all substitute parts suitable for automotive applications?

A: Yes. All substitute parts maintain AEC-Q200 automotive qualification and anti-sulfur construction, identical to the original part. They are suitable for automotive circuit applications.

Q: Can I use a substitute part with tighter tolerance than required?

A: Yes. Using a substitute part with tighter tolerance than required does not create compatibility issues. Tighter tolerance represents improved performance and is acceptable for direct substitution.

Q: Are the substitute parts RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant, matching the compliance status of the original RG2012V-7871-C-T5.
