Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RPC2512KT100R is determined by the following criteria:

Mandatory Parameters for Substitution:

• Resistance value: 100 Ohms (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

Allowable Parameter Variations:

• Tolerance: May be tighter (±5% or ±1%) than the original ±10%
• Power Rating: May be equal or higher than 1.5W
• Automotive Rating: AEC-Q200 certification is preferred but not mandatory for non-automotive applications
• Moisture Sensitivity Level: MSL 1 (Unlimited) is standard across all candidates

All substitute parts listed maintain identical resistance, package, composition, temperature coefficient, and operating range specifications. Variations in tolerance and power rating represent upgrades or equivalent alternatives suitable for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (Automotive AEC-Q200 Applications):

RPC2512JT100R and CRCW2512100RFKEGHP are suitable direct substitutes for the RPC2512KT100R in automotive AEC-Q200 rated applications. Both maintain the 1.5W power rating and 2512 package while offering improved tolerance specifications (±5% and ±1% respectively). Both parts retain AEC-Q200 certification and ROHS3 compliance.

Enhanced Performance Alternatives (Automotive AEC-Q200 Applications):

CRM2512AFX-1000ELF provides increased power dissipation capability (2.0W) with ±1% tolerance and AEC-Q200 certification. This part includes anti-sulfur features and is suitable for applications requiring higher thermal margin or stricter tolerance control.

Non-Automotive Applications:

RHC2512FT100R, AS25J1000ET, and CRM2512-FX-1000ELF are suitable for non-automotive applications where AEC-Q200 certification is not required. RHC2512FT100R and CRM2512-FX-1000ELF offer 2.0W power rating with ±1% tolerance. AS25J1000ET provides ±5% tolerance at 1.5W equivalent to the original specification.

All substitute parts maintain identical resistance value, package dimensions, temperature coefficient, and operating temperature range. Selection should be based on application requirements for tolerance precision, power dissipation margin, and automotive qualification necessity.

Frequently Asked Questions (FAQ)

Q: Can RPC2512JT100R replace RPC2512KT100R in all applications?

A: Yes, RPC2512JT100R is a direct substitute. It maintains identical resistance (100 Ohms), power rating (1.5W), package (2512), temperature coefficient (±100ppm/°C), and operating range (-55°C ~ 155°C). The tolerance is improved from ±10% to ±5%, and AEC-Q200 certification is retained.

Q: What is the difference between RPC2512KT100R and CRCW2512100RFKEGHP?

A: Both parts share identical electrical specifications: 100 Ohms resistance, 1.5W power rating, 2512 package, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. CRCW2512100RFKEGHP offers tighter tolerance (±1% versus ±10%) and is manufactured by Vishay Dale instead of Stackpole Electronics Inc. Both are AEC-Q200 rated and ROHS3 compliant.

Q: Can I use CRM2512AFX-1000ELF as a substitute?

A: CRM2512AFX-1000ELF is compatible for substitution. It maintains the 100 Ohms resistance, 2512 package, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. The power rating is increased to 2.0W (versus 1.5W), and tolerance is ±1% (versus ±10%). AEC-Q200 certification and anti-sulfur features are included. This part is suitable for applications requiring higher power dissipation capability.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant and maintain MSL 1 (Unlimited) moisture sensitivity rating, matching the original RPC2512KT100R specification.

Q: Which substitute should I use for automotive applications?

A: For automotive applications requiring AEC-Q200 certification, use RPC2512JT100R, CRCW2512100RFKEGHP, or CRM2512AFX-1000ELF. All three maintain AEC-Q200 rating. RPC2512JT100R and CRCW2512100RFKEGHP preserve the 1.5W power rating, while CRM2512AFX-1000ELF provides 2.0W capability.

Q: What is the physical dimension difference between substitute parts?

A: All substitute parts use the 2512 (6432 Metric) package with minor dimensional variations within manufacturing tolerance. Length ranges from 0.248" to 0.250" (6.30mm to 6.35mm), width from 0.122" to 0.126" (3.10mm to 3.20mm), and height from 0.026" to 0.031" (0.65mm to 0.80mm). These variations are within standard PCB footprint compatibility for 2512 packages.
