Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 1676198-3 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 15.8 kOhms
• Tolerance: ±0.1% or tighter
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±10ppm/°C
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variations:

• Power rating: Equal to or greater than 0.1W
• Operating temperature range: Must encompass or exceed -55°C ~ 155°C
• Product status: Active preferred over obsolete
• Certifications and features: May include additional automotive or environmental ratings

The substitute parts listed below meet all mandatory matching parameters. Variations in power rating and operating temperature represent upgrades that maintain or exceed the original specification requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Specifications):

RNCF0805BKT15K8 (Stackpole Electronics) and RG2012N-1582-B-T5 (Susumu) provide direct functional equivalence with identical resistance, tolerance, and temperature coefficient. Both are active products with automotive AEC-Q200 certification, offering improved product lifecycle status compared to the obsolete 1676198-3. Power rating increase from 0.1W to 0.125W represents a margin improvement without design impact.

Enhanced Tolerance Substitutes:

RG2012N-1582-W-T1 and RG2012N-1582-W-T5 (Susumu) offer tighter tolerance at ±0.05% versus the original ±0.1%, with identical power and temperature specifications. These components are suitable for applications requiring improved precision while maintaining all other electrical characteristics. Both include anti-sulfur and automotive AEC-Q200 features.

Upgraded Performance Substitutes:

TNPW080515K8BYEA and TNPW080515K8BYEN (Vishay Dale) provide significant power rating upgrade to 0.26W and extended operating temperature range to -55°C ~ 175°C. These components maintain ±0.1% tolerance and include anti-sulfur, automotive AEC-Q200, and moisture-resistant features. Selection is appropriate for applications requiring enhanced thermal margin or extended temperature operation.

All substitute parts maintain RoHS3 compliance, REACH unaffected status, and MSL 1 rating consistent with the original component.

Frequently Asked Questions (FAQ)

Q: Can RNCF0805BKT15K8 be used as a direct replacement for 1676198-3?

A: Yes. RNCF0805BKT15K8 meets all mandatory electrical and mechanical parameters: 15.8 kOhms resistance, ±0.1% tolerance, 0805 package, thin film composition, and ±10ppm/°C temperature coefficient. The 0.125W power rating exceeds the original 0.1W requirement. Operating temperature range and MSL rating are identical.

Q: What is the difference between the Susumu RG2012N-1582-W-T1 and RG2012N-1582-B-T5 variants?

A: Both components share identical electrical specifications (15.8 kOhms, 0.125W, ±10ppm/°C, -55°C ~ 155°C). The primary difference is tolerance: RG2012N-1582-W-T1 and RG2012N-1582-W-T5 offer ±0.05% tolerance, while RG2012N-1582-B-T5 maintains ±0.1% tolerance matching the original specification. Selection depends on circuit precision requirements.

Q: Are the Vishay Dale TNPW080515K8BYEA and TNPW080515K8BYEN parts interchangeable?

A: Yes. Both parts are electrically and mechanically identical: 15.8 kOhms, ±0.1% tolerance, 0.26W power rating, 0805 package, and -55°C ~ 175°C operating range. Both include anti-sulfur, automotive AEC-Q200, and moisture-resistant features. Selection between them is based on procurement availability and supply chain considerations.

Q: Can I use a substitute with higher power rating in place of the 1676198-3?

A: Yes. Higher power rating components (0.125W or 0.26W) are functionally compatible with circuits designed for 0.1W operation. The increased power rating provides thermal margin and does not affect circuit performance. Physical dimensions remain identical in the 0805 package.

Q: What is the significance of the anti-sulfur feature in substitute parts?

A: Anti-sulfur coating protects resistor terminations from corrosion in environments with hydrogen sulfide exposure. This feature is included in Susumu and Vishay Dale substitutes but not in the original 1676198-3. It provides enhanced reliability in industrial and automotive applications without affecting standard circuit operation.

Q: Are all substitute parts automotive qualified?

A: Yes. All listed substitute parts carry automotive AEC-Q200 certification. The original 1676198-3 does not specify automotive qualification. AEC-Q200 certification indicates compliance with automotive reliability and quality standards, providing enhanced assurance for mission-critical applications.

Q: Does tolerance difference affect circuit compatibility?

A: Tolerance affects resistor value accuracy but not circuit functionality. The original ±0.1% tolerance is maintained by RNCF0805BKT15K8, RG2012N-1582-B-T5, and both Vishay Dale parts. Susumu RG2012N-1582-W variants offer tighter ±0.05% tolerance, which improves precision in applications requiring close value matching but is not required for standard circuit operation.

Q: Can I mix different substitute parts in the same circuit?

A: Yes. All substitute parts meet identical mandatory parameters and are electrically interchangeable. Mixing different manufacturers or variants in the same circuit does not create compatibility issues. Selection can be based on procurement availability, cost, or specific feature requirements per application.
