Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PRF15BE103RB6RC is determined by the following critical parameters:

• Resistance value at 25°C: 10 kOhms (exact match required)
• Package / Case format: 0402 (1005 Metric) (exact match required)
• Mounting type: Surface Mount (exact match required)
• Manufacturer: Murata Electronics (same manufacturer preferred for consistency)

The substitute parts listed below meet these core electrical and mechanical requirements. Variations in resistance tolerance, operating temperature range, and product status reflect different product lines within the same manufacturer's portfolio.

Parameter Comparison

Engineering Selection Recommendations

For designs currently using PRF15BE103RB6RC, the PRF15BB103RB6RC is the primary upgrade path. Both components belong to the Posistor® series, maintain identical 10 kOhms resistance at 25°C, share the same 0402 package format, and are ROHS3 compliant. The PRF15BB103RB6RC offers an extended operating temperature range (-20°C ~ 140°C versus -20°C ~ 95°C) and maintains Active product status, ensuring long-term availability.

The TPM0S103P100R from the TPM-S series provides an alternative from Murata Electronics with matching resistance and package specifications. This part is currently Active and available in inventory. However, the operating temperature range is not specified in the available data, requiring verification against specific application requirements before selection.

Frequently Asked Questions (FAQ)

Q: Can PRF15BE103RB6RC be directly replaced with PRF15BB103RB6RC?

A: Yes. Both parts maintain 10 kOhms resistance at 25°C, use the same 0402 (1005 Metric) surface-mount package, and are manufactured by Murata Electronics. The PRF15BB103RB6RC extends the operating temperature range to 140°C and is in Active product status.

Q: What is the difference between ±5°C and ±50% tolerance specifications?

A: The PRF15BE103RB6RC specifies ±5°C tolerance, while substitute parts specify ±50% tolerance. These represent different tolerance measurement methods. Applications requiring the tighter ±5°C specification should verify compatibility with ±50% tolerance alternatives.

Q: Why is PRF15BE103RB6RC in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this specific part number. Designs should transition to active alternatives such as PRF15BB103RB6RC to ensure continued component availability.

Q: Are all substitute parts available in the same packaging format?

A: All listed substitute parts use the 0402 (1005 Metric) package format suitable for surface-mount assembly. Packaging options (Tape & Reel, Cut Tape, Digi-Reel®) may vary by supplier and part number.

Q: Which substitute part should be selected for new designs?

A: For new designs, PRF15BB103RB6RC is recommended. It maintains the Posistor® series designation, offers extended temperature range, and is in Active product status with established supply chain availability.
