KAL25JB5R00 Equivalent & Substitute Parts

Part Overview

The KAL25JB5R00 is a 5 Ohms ±5% 25W wirewound chassis mount resistor manufactured by Stackpole Electronics Inc. This component is classified as Active product status with ROHS3 compliance. Equivalent and substitute parts are identified when design requirements permit tolerance relaxation, manufacturer transitions, or packaging format changes while maintaining core electrical and mechanical compatibility within the specified operating parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution relationships for the KAL25JB5R00 are established based on the following criteria:

Parametric Equivalents maintain identical resistance (5 Ohms), power rating (25W), composition (wirewound), temperature coefficient (±50ppm/°C), housing type (aluminum), mounting features (flanges), and lead style (solder lugs). Tolerance may be tighter (±1% vs ±5%) without affecting functional compatibility. Dimensional variations within manufacturing tolerances and packaging format changes (bulk to tray) are permitted.

Upgrade Substitutes meet all core electrical parameters while introducing enhanced features or alternative manufacturer sourcing. These parts maintain 5 Ohms resistance, 25W power rating, wirewound composition, ±50ppm/°C temperature coefficient, aluminum housing, flanged mounting, and solder lug leads. Operating temperature range and dimensional specifications remain within acceptable substitution boundaries.

Manufacturer Recommended Substitutes are designated by original equipment manufacturers as approved alternatives. These parts match the primary electrical specifications (5 Ohms, ±5% tolerance, 25W) and mechanical form factor while originating from different manufacturers. Operating temperature range may differ (200°C maximum vs 275°C maximum).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain Active product status and ROHS3 compliance, qualifying them for direct substitution within applications where the specified electrical and mechanical parameters are acceptable.

KAL25FB5R00 (Stackpole Electronics Inc) provides parametric equivalence with improved tolerance specification (±1% vs ±5%), maintaining identical operating temperature range (-55°C ~ 275°C) and bulk packaging format.

825F5R0E (Ohmite, Metal-Mite®89 series) and UAL25-5RF8 (Riedon, UAL series) deliver upgrade substitution with ±1% tolerance and full operating temperature range (-55°C ~ 275°C). The 825F5R0E is supplied in tray packaging; the UAL25-5RF8 is supplied in bulk packaging.

HSA255R0J and THS255R0J (TE Connectivity Passive Product, HS/THS series) are manufacturer-recommended alternatives with matching ±5% tolerance. These parts operate within a reduced temperature range (-55°C ~ 200°C). HSA255R0J is supplied in bulk packaging; THS255R0J is supplied in tray packaging.

Frequently Asked Questions (FAQ)

Q: Can KAL25FB5R00 replace KAL25JB5R00 in all applications?

A: Yes. KAL25FB5R00 maintains identical resistance (5 Ohms), power rating (25W), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 275°C), housing type (aluminum), mounting features (flanges), and lead style (solder lugs). The tighter tolerance specification (±1% vs ±5%) does not restrict compatibility.

Q: What is the primary difference between Stackpole and Ohmite substitutes?

A: KAL25FB5R00 (Stackpole) and 825F5R0E (Ohmite) are electrically equivalent with identical tolerance (±1%), temperature coefficient (±50ppm/°C), and operating range (-55°C ~ 275°C). The primary difference is packaging format: KAL25FB5R00 is supplied in bulk; 825F5R0E is supplied in tray.

Q: Are TE Connectivity parts suitable for high-temperature applications?

A: HSA255R0J and THS255R0J operate within -55°C ~ 200°C. Applications requiring operation above 200°C must use KAL25JB5R00, KAL25FB5R00, 825F5R0E, or UAL25-5RF8, which all support -55°C ~ 275°C.

Q: Does packaging format affect electrical performance?

A: No. Bulk and tray packaging formats do not affect electrical characteristics. Selection between bulk and tray packaging is determined by procurement and assembly process requirements.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the compliance status of KAL25JB5R00.
