825F1K5 Equivalent & Substitute Parts

Part Overview

The 825F1K5 is a 1.5 kOhms ±1% 25W wirewound chassis mount resistor manufactured by Ohmite in the Metal-Mite®89 series. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing system maintenance, repair, and production continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives within the same parameter envelope.

Substitute Part Grouping Explanation

Substitution of the 825F1K5 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 1.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 25W (exact match required)
• Composition: Wirewound (exact match required)
• Temperature Coefficient: ±20ppm/°C (exact match required)
• Housing Type: Aluminum (exact match required)
• Mounting Feature: Flanges (exact match required)
• Lead Style: Solder Lugs (exact match required)
• Package Type: Axial, Box (exact match required)

Two substitute parts meet these criteria: the 825F1K5E (ARCOL) and the KAL25FB1K50 (Stackpole Electronics Inc). Both components maintain identical electrical specifications and mechanical mounting characteristics, enabling direct functional replacement in applications originally designed for the 825F1K5.

Parameter Comparison

Engineering Selection Recommendations

825F1K5E (ARCOL): This substitute part is electrically and mechanically equivalent to the 825F1K5. The component is currently in active production status and carries RoHS compliance certification. Physical dimensions show minimal variation (1.075" L x 1.102" W versus 1.062" L x 1.094" W), with height differences of 0.027" (0.68mm). This part is suitable for applications where RoHS compliance is required.

KAL25FB1K50 (Stackpole Electronics Inc): This substitute part maintains full electrical equivalence and is in active production. The KAL series component provides ROHS3 compliance and includes moisture-resistant features. Physical dimensions are nearly identical to the original 825F1K5 (1.062" L x 1.080" W), with a height difference of 0.021" (0.54mm). This part is suitable for applications requiring enhanced environmental protection and modern compliance standards.

Both substitute parts are available in bulk packaging and maintain adequate inventory levels for procurement.

Frequently Asked Questions (FAQ)

Q: Can the 825F1K5E and KAL25FB1K50 be used interchangeably with the 825F1K5?

A: Both parts meet the electrical and mechanical specifications of the 825F1K5. Physical dimensions are within acceptable tolerance for standard chassis mount applications. Direct substitution is supported for applications where the original part specifications are maintained.

Q: What is the difference between the two substitute parts?

A: The 825F1K5E (ARCOL) and KAL25FB1K50 (Stackpole) are both electrically equivalent. The KAL25FB1K50 includes moisture-resistant features and ROHS3 compliance, while the 825F1K5E provides RoHS compliance. Selection depends on application environmental requirements and compliance mandates.

Q: Are there dimensional compatibility concerns with these substitutes?

A: All three parts use identical mounting features (flanges with solder lugs) and package types (axial, box). Dimensional variations are minor (less than 0.03" in length and width, less than 0.03" in height) and do not affect standard chassis mount applications.

Q: Why is the 825F1K5 listed as obsolete?

A: The 825F1K5 is no longer in active production. The 825F1K5E and KAL25FB1K50 are current production alternatives that maintain full functional equivalence.

Q: What compliance differences exist between the original and substitute parts?

A: The original 825F1K5 is RoHS non-compliant. Both substitute parts carry modern compliance certifications: 825F1K5E is RoHS compliant, and KAL25FB1K50 is ROHS3 compliant. Applications requiring regulatory compliance should specify one of the substitute parts.
