Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012V-7151-B-T1 is determined by the following critical parameters:

Mandatory Compatibility Parameters:

• Resistance value: 7.15 kOhms (exact match required)
• Power rating: 0.125W (1/8W) minimum
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

Tolerance Flexibility: Substitutes with equal or tighter tolerance specifications (±0.1%, ±0.05%, ±0.02%) are electrically compatible. Tighter tolerances represent performance upgrades without functional degradation.

Packaging Variation: The original part is supplied in cut tape format (T1). Substitutes supplied in Tape & Reel (T5) format are mechanically compatible and represent standard production packaging.

Temperature Range Consideration: The original part operates to 155°C. Substitutes with reduced upper temperature limits (125°C) remain compatible for applications not requiring the full temperature range.

Manufacturer Variation: Cross-manufacturer substitutes (Susumu to Vishay Dale) are acceptable when all electrical and mechanical parameters align and automotive qualification is maintained.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance):

RG2012V-7151-B-T5 and TNPU08057K15BZEN00 are direct electrical equivalents to the RG2012V-7151-B-T1, maintaining identical resistance value and tolerance specification of ±0.1%. Both parts are active products with full AEC-Q200 automotive qualification and ROHS3 compliance. The RG2012V-7151-B-T5 represents the same manufacturer continuation with standard Tape & Reel packaging. The TNPU08057K15BZEN00 provides cross-manufacturer equivalence from Vishay Dale with moisture-resistant thin film construction. Selection between these options depends on supply chain preference and existing qualification documentation.

Upgraded Tolerance Options:

RG2012V-7151-P-T1 (±0.02% tolerance) and RG2012V-7151-W-T1 / RG2012V-7151-W-T5 (±0.05% tolerance) offer tighter tolerance specifications than the original part. These upgrades provide enhanced precision for applications requiring improved accuracy without any electrical or mechanical compromise. All three upgraded options maintain identical power rating, package dimensions, temperature coefficient, and automotive qualification. Selection of upgraded tolerance depends on circuit design requirements and cost considerations.

Temperature Range Consideration:

TNPU08057K15BZEN00 operates to 125°C maximum, compared to 155°C for all Susumu variants. This part remains suitable for applications with maximum operating temperatures at or below 125°C. For designs requiring full -55°C to 155°C range, Susumu alternatives are required.

Frequently Asked Questions (FAQ)

Q: Can RG2012V-7151-B-T5 directly replace RG2012V-7151-B-T1 in production?

A: Yes. Both parts are electrically and mechanically identical with matching 7.15 kOhms ±0.1% specifications, 0805 package, and AEC-Q200 qualification. The difference is packaging format: T1 indicates cut tape, T5 indicates Tape & Reel. Standard production typically uses Tape & Reel format.

Q: What is the difference between the tolerance variants?

A: RG2012V-7151-B-T1 specifies ±0.1% tolerance, RG2012V-7151-W variants specify ±0.05%, and RG2012V-7151-P-T1 specifies ±0.02%. Tighter tolerance means the actual resistance value remains closer to the nominal 7.15 kOhms specification. All variants are electrically compatible; tighter tolerance represents improved precision.

Q: Is TNPU08057K15BZEN00 from Vishay Dale a suitable cross-manufacturer substitute?

A: Yes, for applications operating at or below 125°C. The part matches all critical electrical parameters (7.15 kOhms ±0.1%, 0.125W, 0805 package, thin film, AEC-Q200, ROHS3). The maximum operating temperature is 125°C versus 155°C for Susumu parts. Verify application temperature requirements before selection.

Q: Does packaging format (T1 vs T5) affect circuit performance?

A: No. T1 (cut tape) and T5 (Tape & Reel) represent different supply formats only. Electrical and mechanical specifications are identical. Selection depends on assembly equipment compatibility and supply chain logistics.

Q: Are all substitute parts ROHS3 compliant and AEC-Q200 qualified?

A: Yes. All listed substitutes maintain ROHS3 compliance and AEC-Q200 automotive qualification, matching the original part's regulatory and quality standards.

Q: Can upgraded tolerance parts be used in circuits designed for ±0.1% tolerance?

A: Yes. Parts with tighter tolerance (±0.05% or ±0.02%) are fully compatible in circuits specified for ±0.1%. The tighter tolerance provides equal or better performance without functional degradation.
