TNP10SC150RFE Equivalent & Substitute Parts

Part Overview

The TNP10SC150RFE is a through-hole resistor manufactured by Ohmite with a resistance value of 150 Ohms and 1% tolerance, rated for 10W power dissipation in a TO-126 package. This component is classified as obsolete, necessitating identification of equivalent substitute parts for ongoing design requirements and procurement needs. Active alternative components with comparable electrical characteristics and mechanical compatibility are available from both Ohmite and other manufacturers.

Substitute Part Grouping Explanation

Substitute parts for the TNP10SC150RFE are identified based on the following critical parameters that determine functional and mechanical compatibility:

Primary Substitution Criteria:

• Resistance value: 150 Ohms (exact match required)
• Composition: Thick film construction
• Through-hole configuration
• RoHS compliance status
• Moisture sensitivity classification

Substitution Logic: The identified substitute parts maintain the core 150 Ohm resistance specification and thick film composition. However, substitutes differ in power rating and package configuration. The AP836 150R J operates at 35W in a TO-220-2 package, while the TBH25P150RJE operates at 25W in a TO-220-2 package. Both substitutes exceed the original 10W rating, providing increased thermal headroom. Package differences (TO-126 versus TO-220-2) require mechanical board layout evaluation. Tolerance specifications vary: the original part specifies ±1%, while both substitutes specify ±5% tolerance.

Parameter Comparison

Engineering Selection Recommendations

TBH25P150RJE (Ohmite) - Primary Substitute: The TBH25P150RJE is the preferred substitute when design constraints permit package transition from TO-126 to TO-220-2. This part maintains Ohmite manufacturer continuity, achieves ROHS3 compliance matching the original specification, and provides 25W power rating with enhanced thermal performance. The TBH series includes current sense and moisture-resistant features. Active product status ensures long-term availability and supply chain stability. The ±5% tolerance specification requires circuit design verification if the original ±1% tolerance was critical to system performance.

AP836 150R J (ARCOL) - Alternative Substitute: The AP836 150R J provides the highest power rating at 35W, suitable for applications requiring maximum thermal margin. This part is RoHS compliant and maintains EAR99 classification. The TO-220-2 package matches the TBH25P150RJE, simplifying board layout standardization if both parts are considered. The ±100ppm/°C temperature coefficient is less stable than the TBH25P150RJE specification. Active product status supports procurement continuity.

Substitution Constraints: Both substitute parts require mechanical board layout modification due to TO-220-2 package dimensions differing from the original TO-126 package. Tolerance degradation from ±1% to ±5% necessitates circuit analysis to confirm acceptable performance margins. The TBH25P150RJE offers superior temperature stability and maintains Ohmite sourcing.

Frequently Asked Questions (FAQ)

Q: Can the AP836 150R J and TBH25P150RJE be used interchangeably? A: Both parts share identical 150 Ohm resistance and TO-220-2 package configuration. The primary differences are power rating (35W versus 25W), temperature coefficient (±100ppm/°C versus ±50ppm/°C), and operating temperature range (-65°C to 150°C versus -55°C to 150°C). Selection depends on thermal requirements and temperature stability specifications for the application.

Q: What is the impact of tolerance change from ±1% to ±5%? A: The original TNP10SC150RFE specifies ±1% tolerance, while both substitutes specify ±5% tolerance. This represents a five-fold increase in acceptable resistance variation. Circuit designs dependent on precise 150 Ohm values require analysis to confirm that ±5% tolerance remains within acceptable performance parameters. Voltage dividers, current-limiting circuits, and precision measurement applications are most sensitive to tolerance degradation.

Q: Are package changes from TO-126 to TO-220-2 mechanically compatible? A: No. The TO-126 and TO-220-2 packages have different physical dimensions and mounting configurations. TO-220-2 packages are larger and require modified PCB footprints, mounting hardware, and thermal management considerations. Board layout redesign is necessary for substitution.

Q: Do all substitute parts maintain RoHS compliance? A: Yes. The TNP10SC150RFE is ROHS3 compliant. The AP836 150R J is RoHS compliant, and the TBH25P150RJE is ROHS3 compliant. All parts meet RoHS requirements for hazardous substance restrictions.

Q: What is the significance of the TBH25P150RJE "Current Sense" feature? A: The current sense designation indicates this resistor is designed for precision current measurement applications. This feature does not affect basic substitution compatibility but indicates optimized performance characteristics for current monitoring circuits.

Q: How do operating temperature ranges affect substitution? A: The TNP10SC150RFE operating temperature range is not specified in available data. The AP836 150R J operates from -65°C to 150°C, while the TBH25P150RJE operates from -55°C to 150°C. Applications requiring operation below -55°C require the AP836 150R J. Both substitutes support the standard industrial temperature range of -55°C to 150°C.

Q: Is moisture sensitivity a factor in substitution? A: The TNP10SC150RFE and AP836 150R J both specify MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The TBH25P150RJE specifies MSL as Not Applicable, indicating moisture-resistant construction. For applications in high-humidity environments, the TBH25P150RJE provides enhanced protection through its moisture-resistant design.
