Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the RG2012P-5491-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 5.49 kOhms
• Package / Case: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Packaging Type: Tape & Reel (TR)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation Parameters:

• Tolerance: The main part specifies ±0.5%. Substitute parts with ±0.1% tolerance are acceptable as they represent improved precision within the same resistance value and maintain backward compatibility.
• Power Rating: The main part specifies 0.125W (1/8W). Substitute parts with equal or higher power ratings (0.25W / 1/4W) are acceptable as they provide equivalent or superior thermal performance.
• Features: Automotive AEC-Q200 qualification is present on the main part and certain substitutes; absence of this feature on other substitutes does not preclude compatibility for non-automotive applications.

Identified substitute parts maintain the core electrical characteristics (resistance, temperature coefficient, operating range) and physical form factor while offering enhanced tolerance grades or increased power capacity.

Parameter Comparison

Engineering Selection Recommendations

RG2012P-5491-B-T5 (Susumu, ±0.1% Tolerance)

This substitute offers improved tolerance specification (±0.1% versus ±0.5%) while maintaining identical power rating, package, and automotive AEC-Q200 qualification. Suitable for applications requiring higher precision resistance values. Significantly higher inventory availability (59,277 units) supports production continuity.

8-2176092-2 (TE Connectivity, 0.25W Power Rating)

This substitute provides increased power dissipation capacity (0.25W versus 0.125W) in the same 0805 package form factor. Maintains ±0.1% tolerance and identical temperature characteristics. Lacks automotive AEC-Q200 certification; suitable for industrial and commercial applications where automotive qualification is not required. Moderate inventory availability (1,807 units).

ERA-6AEB5491V (Panasonic, ±0.1% Tolerance)

This substitute delivers improved tolerance specification (±0.1% versus ±0.5%) with maintained power rating and automotive AEC-Q200 qualification. Panasonic ERA-6A series thin film resistors provide equivalent performance characteristics. Adequate inventory availability (7,898 units) supports standard procurement cycles.

RT0805BRD075K49L (YAGEO, ±0.1% Tolerance)

This substitute offers enhanced tolerance specification (±0.1% versus ±0.5%) with identical power rating and package specifications. YAGEO RT series thin film resistors maintain equivalent temperature coefficient and operating range. Does not carry automotive AEC-Q200 certification; applicable for general industrial and commercial applications. Inventory availability (2,912 units) supports typical component sourcing requirements.

Frequently Asked Questions (FAQ)

Q: Can I substitute RG2012P-5491-D-T5 with a part having ±0.1% tolerance?

A: Yes. Parts with ±0.1% tolerance (RG2012P-5491-B-T5, ERA-6AEB5491V, RT0805BRD075K49L) are direct substitutes. The ±0.1% tolerance represents improved precision and is compatible with applications designed for ±0.5% tolerance specifications.

Q: Is the 8-2176092-2 (0.25W) suitable as a direct replacement for the 0.125W main part?

A: Yes. The 8-2176092-2 provides equal or superior thermal performance due to its higher power rating. The increased power capacity does not affect electrical compatibility in circuits designed for 0.125W operation. Physical dimensions remain within 0805 package specifications.

Q: What is the difference between automotive-rated and non-automotive substitute parts?

A: Automotive-rated parts (RG2012P-5491-B-T5, ERA-6AEB5491V) carry AEC-Q200 certification, indicating compliance with automotive reliability and environmental stress testing standards. Non-automotive parts (8-2176092-2, RT0805BRD075K49L) are suitable for industrial and commercial applications. Selection depends on end-application requirements.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All identified substitute parts are supplied in Tape & Reel (TR) packaging, maintaining compatibility with automated assembly processes and standard component handling procedures.

Q: Do substitute parts maintain the same operating temperature range?

A: Yes. All substitute parts operate across the identical temperature range of -55°C to 155°C with ±25ppm/°C temperature coefficient, ensuring thermal performance equivalence.

Q: Which substitute part offers the best inventory availability?

A: RG2012P-5491-B-T5 (Susumu) provides the highest inventory availability with 59,277 units in stock, followed by ERA-6AEB5491V (Panasonic) with 7,898 units and RT0805BRD075K49L (YAGEO) with 2,912 units.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts maintain ROHS3 compliance and Moisture Sensitivity Level 1 (Unlimited), matching the environmental and regulatory status of the main part.
