Key Parameters

Substitute Part Grouping Explanation

The 502AS101KDG2 is identified as a parametric equivalent based on the following criteria:

Matching Parameters:

• Resistance value: 100 Ohms
• Tolerance: ±10%
• Composition: Ceramic
• Temperature Coefficient: 0 / -800ppm/°C
• Operating Temperature Range: -55°C to 230°C
• Lead Style: Solder Lugs
• Package / Case: Radial, Flat Oval
• Series: 500 (Ohmite)
• Manufacturer: Ohmite

Differing Parameters:

• Power Rating: 504AS101KDG2 = 24W; 502AS101KDG2 = 12W
• Physical Dimensions: 504AS101KDG2 = 4.000" L × 0.252" W; 502AS101KDG2 = 2.000" L × 0.252" W

Substitution is valid when the application circuit requires 12W or less power dissipation at 100 Ohms resistance within the specified temperature range.

Parameter Comparison

Engineering Selection Recommendations

Selection between 504AS101KDG2 and 502AS101KDG2 is determined by power dissipation requirements:

Use 504AS101KDG2 when:

• Circuit design requires power dissipation between 12W and 24W at 100 Ohms
• Thermal management design accommodates the larger physical footprint (4.000" length)
• PCB layout permits the extended component dimensions

Use 502AS101KDG2 when:

• Circuit design requires power dissipation of 12W or less at 100 Ohms
• Space constraints require the smaller footprint (2.000" length)
• Thermal environment supports reduced power rating

Both parts maintain identical electrical characteristics (resistance, tolerance, temperature coefficient, operating range) and are manufactured by Ohmite within the active 500 series. Both parts carry RoHS non-compliant status.

Frequently Asked Questions (FAQ)

Q: Can 502AS101KDG2 replace 504AS101KDG2 in all applications?

A: No. The 502AS101KDG2 has a maximum power rating of 12W, while the 504AS101KDG2 is rated for 24W. Substitution is valid only when the application circuit dissipates 12W or less at 100 Ohms resistance.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both parts share identical resistance (100 Ohms), tolerance (±10%), temperature coefficient (0 / -800ppm/°C), and operating temperature range (-55°C to 230°C). The primary difference is power rating and physical size.

Q: What are the physical dimension differences?

A: The 504AS101KDG2 measures 4.000" L × 0.252" W, while the 502AS101KDG2 measures 2.000" L × 0.252" W. Both have identical height when seated (1.500" maximum). The width and height dimensions are identical; only the length differs.

Q: Do these parts require different mounting considerations?

A: Both parts use solder lugs and require brackets (not included) for mounting. The reduced length of the 502AS101KDG2 may simplify PCB layout in space-constrained designs, but mounting methodology remains consistent.

Q: Are there compliance or certification differences?

A: Both parts carry identical RoHS non-compliant status and share the same ECCN and HTSUS classifications within their respective packaging configurations.
