AP725 200R F Equivalent & Substitute Parts

Part Overview

The AP725 200R F is a 200 Ohm ±1% 20W thick film chip resistor manufactured by Ohmite in the TO-263-3 (D2PAK) package. This component is designed for applications requiring precision resistance with moderate power dissipation in a compact surface-mount form factor. The part is currently active in production with full RoHS compliance and unlimited moisture sensitivity rating, making it suitable for industrial and commercial applications across extended temperature ranges.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained within the allowed parameter tolerances for this product category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AP725 200R F is determined by strict equivalence in the following parameters:

• Resistance Value: Must be 200 Ohms
• Tolerance: Must be ±1%
• Package Type: Must be TO-263-3 (D2PAK) with 2 leads plus tab
• Composition: Must be thick film construction
• Temperature Coefficient: Must be ±100ppm/°C or better
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Number of Terminations: Must be 2

The PWR263S-35-2000F meets all substitution criteria. While this part features a higher power rating (35W versus 20W), this represents an upgrade capability that maintains full backward compatibility. The increased power dissipation capacity does not compromise performance in applications designed for the 20W specification.

Parameter Comparison

Engineering Selection Recommendations

AP725 200R F (Ohmite): Select this part for applications where the 20W power specification is the design requirement and Ohmite component qualification is mandated. The part maintains active production status with standard RoHS compliance.

PWR263S-35-2000F (Bourns Inc.): This part is suitable as a direct substitute with enhanced thermal performance. The 35W power rating provides additional margin in applications subject to thermal stress or power cycling. The part includes automotive AEC-Q200 qualification and current sense features, making it appropriate for automotive and industrial applications requiring higher reliability standards. ROHS3 compliance indicates updated environmental qualification.

Both parts are active in production and maintain identical electrical and mechanical compatibility within the TO-263-3 package footprint.

Frequently Asked Questions (FAQ)

Q: Can PWR263S-35-2000F replace AP725 200R F in existing designs?

A: Yes. Both parts share identical resistance (200 Ohms), tolerance (±1%), package type (TO-263-3 D2PAK), and operating temperature range (-55°C to 155°C). The PWR263S-35-2000F provides higher power dissipation capability (35W versus 20W), which is compatible with designs specified for 20W operation.

Q: Are there physical dimension differences between these parts?

A: Both parts use the TO-263-3 (D2PAK) package with 2 leads plus tab. The PWR263S-35-2000F has a larger width dimension (10.40mm versus 4.50mm) and different height (4.50mm versus 4.88mm). PCB layout must accommodate the PWR263S-35-2000F footprint dimensions.

Q: What is the significance of the AEC-Q200 rating on the PWR263S-35-2000F?

A: AEC-Q200 is an automotive qualification standard. This certification indicates the part meets automotive reliability and environmental stress testing requirements. It is not required for non-automotive applications but provides additional assurance of component quality and consistency.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements and supplier qualification. For new designs without existing component qualification constraints, the PWR263S-35-2000F offers higher thermal margin and automotive-grade reliability. For designs with established Ohmite component requirements, the AP725 200R F maintains specification compliance.
