Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0728K7L is determined by the following critical parameters:

• Resistance Value: Must be 28.7 kOhms (exact match required)
• Package Type: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Composition: Thin film construction maintains electrical performance characteristics
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Compliance: RoHS3 compliance and MSL 1 rating required for standard applications

Tolerance, power rating, and temperature coefficient may vary within acceptable engineering limits for specific application requirements. Automotive-grade parts (AEC-Q200 rated) represent upgrades suitable for automotive and high-reliability applications.

Parameter Comparison

Engineering Selection Recommendations

ERA-8AEB2872V (Panasonic) — This substitute provides improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package dimensions. AEC-Q200 automotive qualification makes this suitable for applications requiring enhanced reliability and tighter tolerance specifications. Footprint compatibility is confirmed with identical 1206 package designation.

RNCF1206BKC28K7 (Stackpole Electronics) — This substitute offers increased power dissipation capability (0.333W vs 0.25W) and improved tolerance (±0.1%) with AEC-Q200 automotive qualification. Slightly different physical dimensions (3.05mm L x 1.55mm W vs 3.10mm L x 1.60mm W) remain within 1206 package specification tolerances. Temperature coefficient remains at ±50ppm/°C. This option is recommended for applications requiring higher power handling or automotive-grade reliability.

Both substitutes maintain full compliance with RoHS3 and MSL 1 requirements, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB2872V be used as a direct replacement for RT1206FRE0728K7L?

A: Yes. Both components share identical resistance value (28.7 kOhms), package type (1206), composition (thin film), and operating temperature range (-55°C to 155°C). The ERA-8AEB2872V provides superior tolerance and temperature stability. Footprint compatibility is confirmed.

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

A: ERA-8AEB2872V maintains the original 0.25W power rating with ±0.1% tolerance and ±25ppm/°C temperature coefficient. RNCF1206BKC28K7 increases power rating to 0.333W with ±0.1% tolerance and ±50ppm/°C temperature coefficient. Both are AEC-Q200 qualified. Select based on power dissipation requirements and temperature stability needs.

Q: Are physical dimensions identical across all three parts?

A: Dimensions vary slightly within 1206 package specification. RT1206FRE0728K7L: 3.10mm L x 1.60mm W. ERA-8AEB2872V: 3.20mm L x 1.60mm W. RNCF1206BKC28K7: 3.05mm L x 1.55mm W. All remain within 1206 package tolerances and are PCB footprint compatible.

Q: Do all parts meet RoHS and MSL requirements?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) rating, meeting standard environmental and moisture sensitivity requirements.

Q: When should I select the higher power-rated RNCF1206BKC28K7?

A: Select RNCF1206BKC28K7 when circuit design requires power dissipation exceeding 0.25W or when automotive-grade reliability with higher power margin is specified. The 0.333W rating provides additional thermal headroom in demanding applications.
