TNP10SC10K0FE Equivalent & Substitute Parts

Part Overview

The TNP10SC10K0FE is a through-hole resistor manufactured by Ohmite with a resistance value of 10,000 ohms, 1% tolerance, and 10W power rating in a TO-126 package. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. The part maintains ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), suitable for applications requiring stable resistive elements in through-hole configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TNP10SC10K0FE is based on the following critical parameters:

Primary Matching Criteria:

• Resistance value: 10 kOhms (exact match required)
• Configuration: Through-hole termination
• Compliance: RoHS compliance maintained
• Moisture sensitivity: MSL 1 rating

Secondary Considerations:

• Power rating: The substitute part must equal or exceed the 10W requirement
• Tolerance: The substitute tolerance may be broader than the original 1% specification
• Package type: Physical form factor may differ while maintaining through-hole compatibility
• Temperature operating range: Must support standard industrial temperature ranges

The AP836 10K J substitute meets the primary matching criteria with identical resistance value and through-hole configuration. The substitute provides higher power dissipation capability (35W versus 10W) and maintains RoHS compliance with MSL 1 rating. Tolerance specification differs at ±5% compared to the original 1%, representing a trade-off acceptable for applications not requiring precision tolerance control.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

The AP836 10K J is a direct functional substitute for the TNP10SC10K0FE based on matching resistance value and through-hole configuration. Both components maintain RoHS compliance and MSL 1 rating, ensuring regulatory and environmental compatibility.

Status Considerations:

The original TNP10SC10K0FE is classified as obsolete, while the AP836 10K J maintains active product status. Selection of the active substitute ensures long-term availability and continued manufacturer support for procurement and technical documentation.

Tolerance Trade-off:

The substitute part specifies ±5% tolerance compared to the original ±1% tolerance. This represents a broader tolerance band suitable for applications where precision resistive values are not critical. Designs requiring the original 1% tolerance specification must evaluate whether the ±5% tolerance is acceptable for circuit performance.

Power Dissipation:

The AP836 10K J provides 35W power rating, exceeding the original 10W specification. This higher power capability offers design margin for thermal management and allows operation in higher-dissipation applications without component derating.

Package Transition:

The substitute uses TO-220-2 package instead of TO-126. Both are through-hole configurations with different physical dimensions. PCB layout modifications may be required to accommodate the different package footprint and lead spacing.

Frequently Asked Questions (FAQ)

Q: Can the AP836 10K J directly replace the TNP10SC10K0FE without circuit modifications?

A: The AP836 10K J provides electrical equivalence in resistance value and through-hole configuration. PCB layout modifications are required due to different package types (TO-220-2 versus TO-126). Tolerance differences (±5% versus ±1%) must be evaluated for circuit performance requirements.

Q: What is the impact of the ±5% tolerance specification on circuit performance?

A: The ±5% tolerance represents a broader acceptable resistance range compared to the original ±1%. Applications sensitive to precise resistive values must verify that the wider tolerance band remains within acceptable circuit operating parameters. Non-critical biasing and load resistor applications typically tolerate ±5% specifications.

Q: Does the higher 35W power rating of the AP836 10K J create any compatibility issues?

A: Higher power rating does not create compatibility issues. The substitute can safely operate at or below the original 10W specification. The increased power capability provides design margin and allows use in higher-dissipation applications without component derating.

Q: Are there compliance differences between the original and substitute parts?

A: Both components maintain RoHS compliance and MSL 1 rating. The original specifies ROHS3 compliance while the substitute specifies RoHS compliance. Both meet current regulatory requirements for hazardous substance restrictions. ECCN classification remains EAR99 for both parts.

Q: What are the physical dimension differences between TO-126 and TO-220-2 packages?

A: The AP836 10K J TO-220-2 package measures 0.400" L x 0.175" W with maximum seated height of 0.748". The original TO-126 package dimensions are not provided in the specification data. PCB footprint and mounting hole spacing require verification before implementation.

Q: Is the AP836 10K J suitable for high-temperature applications?

A: The AP836 10K J specifies operating temperature range of -65°C to 150°C with temperature coefficient of ±100ppm/°C. This range supports standard industrial applications. Specific high-temperature requirements must be evaluated against the stated operating limits.

Q: What is the composition difference between the original and substitute parts?

A: The substitute part specifies thick film composition with non-inductive characteristics. The original part composition is not specified in available documentation. Thick film construction is standard for power resistor applications and provides stable performance across the operating temperature range.
