Key Parameters

Substitute Part Grouping Explanation

The HS15 1K F qualifies as a parametric equivalent to the HS15 1K J based on the following matching criteria:

• Identical resistance value: 1 kOhms
• Identical power rating: 15W
• Identical composition: Wirewound
• Identical temperature coefficient: ±25ppm/°C
• Identical housing type: Aluminum with flanged mounting
• Identical physical dimensions: 0.783" L x 0.440" W (19.90mm x 11.20mm)
• Identical height: 0.433" (11.00mm)
• Identical lead style: Solder Lugs
• Identical RoHS compliance: ROHS3 Compliant

The primary difference is tolerance specification: the HS15 1K J carries ±5% tolerance, while the HS15 1K F carries ±1% tolerance. This represents an improvement in tolerance performance without any change to mechanical or thermal characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the HS15 1K J and HS15 1K F are active products with ROHS3 compliance and identical mechanical and thermal specifications. The HS15 1K F provides improved tolerance performance at ±1% compared to the ±5% tolerance of the HS15 1K J, while maintaining all other electrical and physical characteristics. Selection between these parts depends on circuit tolerance requirements: applications requiring tighter resistance tolerance specifications should use the HS15 1K F, while applications with ±5% tolerance margins can use either part. Both parts are suitable for direct substitution in chassis-mounted resistor applications with identical mounting and thermal performance.

Frequently Asked Questions (FAQ)

Q: Can the HS15 1K F directly replace the HS15 1K J in existing designs?

A: Yes. The HS15 1K F is mechanically and electrically compatible with the HS15 1K J. All physical dimensions, mounting features, power rating, and thermal characteristics are identical. The HS15 1K F offers improved tolerance performance without requiring any design modifications.

Q: What is the significance of the tolerance difference between these parts?

A: The HS15 1K J has ±5% tolerance, meaning the actual resistance value can vary between 950 Ohms and 1050 Ohms. The HS15 1K F has ±1% tolerance, meaning the actual resistance value can vary between 990 Ohms and 1010 Ohms. Applications requiring tighter resistance accuracy should specify the HS15 1K F.

Q: Are the physical dimensions and mounting features identical?

A: Yes. Both parts share identical dimensions of 0.783" L x 0.440" W (19.90mm x 11.20mm), identical seated height of 0.433" (11.00mm), identical aluminum housing, flanged mounting features, and solder lug lead style. No PCB layout or mechanical modifications are required for substitution.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the HS15 1K J and HS15 1K F are ROHS3 compliant and carry identical ECCN (EAR99) and HTSUS (8533.21.0080) classifications.

Q: What is the temperature coefficient specification for these resistors?

A: Both parts have a temperature coefficient of ±25ppm/°C, indicating identical thermal stability across the operating temperature range.
