Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TNPW0805147KBETA is determined by the following critical parameters:

• Resistance value: 147 kOhms (exact match required)
• Tolerance: ±0.1% (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±25ppm/°C (exact match required)
• Number of Terminations: 2 (exact match required)
• Physical dimensions: 0.079" L x 0.049" W, Height 0.022" max (exact match required)

The substitute part TNPW0805147KBEEA meets all critical electrical and mechanical parameters. Differences exist in power rating, operating temperature range, packaging format, and compliance certifications, which may be advantageous depending on application requirements.

Engineering Selection Recommendations

The TNPW0805147KBEEA serves as a direct electrical and mechanical substitute for the TNPW0805147KBETA. Selection between these parts should be based on the following criteria:

Select TNPW0805147KBETA when military-grade specifications are required and RoHS compliance is not a constraint.

Select TNPW0805147KBEEA when ROHS3 compliance is mandatory, automotive qualification (AEC-Q200) is required, or when higher operating temperature capability (-55°C ~ 175°C) is needed. The increased power rating (0.26W versus 0.125W) provides additional thermal margin in applications with higher power dissipation. The anti-sulfur and moisture-resistant features provide enhanced environmental protection.

Both parts are in active production status and maintain identical electrical performance characteristics within the specified tolerance and temperature coefficient parameters.

Frequently Asked Questions (FAQ)

Q: Can TNPW0805147KBEEA be used as a direct replacement for TNPW0805147KBETA?

A: Yes. Both parts share identical resistance value (147 kOhms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), package format (0805), and physical dimensions. The substitute part meets all critical electrical and mechanical requirements for direct substitution.

Q: What are the key differences between these two parts?

A: The primary differences are power rating (0.125W versus 0.26W), operating temperature range (-55°C ~ 125°C versus -55°C ~ 175°C), RoHS compliance status (non-compliant versus ROHS3 compliant), packaging format (Tape & Reel versus Cut Tape & Digi-Reel), and feature set (military versus automotive AEC-Q200 with anti-sulfur and moisture-resistant properties).

Q: Does the higher power rating of TNPW0805147KBEEA affect circuit performance?

A: No. The higher power rating does not alter electrical performance. It indicates the component can safely dissipate more power without exceeding temperature limits. In applications where the TNPW0805147KBETA operates within its 0.125W rating, the TNPW0805147KBEEA will perform identically.

Q: Are there packaging compatibility considerations?

A: Yes. The TNPW0805147KBETA is supplied in Tape & Reel (TR) format, while the TNPW0805147KBEEA is supplied in Cut Tape (CT) & Digi-Reel® format. Verify that your assembly process and equipment are compatible with the substitute part's packaging format.

Q: Which part should be selected for automotive applications?

A: The TNPW0805147KBEEA is qualified to AEC-Q200 automotive standards and includes anti-sulfur and moisture-resistant features, making it the appropriate choice for automotive applications.

Q: Is RoHS compliance a factor in part selection?

A: Yes. If ROHS3 compliance is a requirement, the TNPW0805147KBEEA must be selected. The TNPW0805147KBETA is RoHS non-compliant and cannot be used in applications with RoHS compliance mandates.
