PAT1206E2002BST1 Equivalent & Substitute Parts

Part Overview

The PAT1206E2002BST1 is a 20 kOhms ±0.1% thin film chip resistor in 1206 (3216 Metric) package rated for 0.4W power dissipation. Manufactured by Vishay Dale, this component features anti-sulfur coating, automotive AEC-Q200 qualification, and moisture resistance suitable for demanding automotive and industrial applications. The part is currently active in production with 998 units in stock. Substitute parts are identified when electrical specifications (resistance value, tolerance, power rating, temperature coefficient) and mechanical compatibility (package, termination count) align with application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PAT1206E2002BST1 is determined by the following criteria:

Mandatory Matching Parameters:

• Resistance value: 20 kOhms
• Tolerance: ±0.1%
• Package / Case: 1206 (3216 Metric)
• Composition: Thin Film
• Number of Terminations: 2
• Temperature Coefficient: ±25ppm/°C
• Features: Anti-Sulfur, Automotive AEC-Q200, Moisture Resistant
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Substitute parts may equal or exceed the 0.4W rating
• Operating Temperature Range: Substitute parts may equal or exceed the upper temperature limit
• Physical dimensions: Minor variations within package specification tolerance

Three substitute parts meet these criteria and are qualified for direct replacement.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are qualified direct replacements for the PAT1206E2002BST1 based on electrical and mechanical parameter alignment. Selection among substitutes should be based on:

RTAN1206BKE20K0 (Stackpole Electronics Inc): Maintains identical power rating (0.4W, 2/5W) and operating temperature range (-55°C ~ 155°C) as the original part. Suitable for applications with strict thermal constraints matching the original specification. Inventory availability: 1318 units.

TNPW120620K0BEEA (Vishay Dale): Provides enhanced power rating (0.52W) and extended operating temperature range (-55°C ~ 175°C). Maintains same manufacturer as original part. Highest inventory availability at 28782 units.

TNPW120620K0BEEN (Vishay Dale): Provides enhanced power rating (0.52W) and extended operating temperature range (-55°C ~ 175°C). Maintains same manufacturer as original part. Inventory availability: 2545 units.

All parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. Physical dimension variations are within 1206 package tolerance specifications.

Frequently Asked Questions (FAQ)

Q: Can TNPW120620K0BEEA or TNPW120620K0BEEN be used as direct replacements for PAT1206E2002BST1?

A: Yes. Both parts meet all mandatory electrical and mechanical parameters. The higher power rating (0.52W vs 0.4W) and extended temperature range (-55°C ~ 175°C vs -55°C ~ 155°C) provide equal or superior performance in the same 1206 package footprint.

Q: What is the difference between TNPW120620K0BEEA and TNPW120620K0BEEN?

A: Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, temperature coefficient, and operating range. Inventory levels differ (28782 vs 2545 units). Selection should be based on supply chain availability and lead time requirements.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within 1206 package specification. PAT1206E2002BST1 and TNPW parts measure 0.126" L x 0.063" W (3.20mm x 1.60mm). RTAN1206BKE20K0 measures 0.122" L x 0.063" W (3.10mm x 1.60mm). All dimensions fall within 1206 (3216 Metric) package tolerance and are PCB footprint compatible.

Q: Do all substitute parts maintain AEC-Q200 automotive qualification?

A: Yes. All three substitute parts carry AEC-Q200 rating, anti-sulfur coating, and moisture resistance equivalent to the original PAT1206E2002BST1.

Q: Which substitute offers the best thermal performance?

A: TNPW120620K0BEEA and TNPW120620K0BEEN both support operating temperatures to 175°C, exceeding the original part's 155°C limit. RTAN1206BKE20K0 matches the original 155°C specification.
