Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-301-D-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 300 Ohms
• Package / Case: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation:

• Tolerance: ±0.5% (main part) to ±0.1% (upgrade substitutes) — tighter tolerance is acceptable
• Automotive rating: AEC-Q200 certification present in main part and some substitutes; absence does not disqualify direct equivalents with identical electrical specifications
• Physical height: Seated height variation between 0.020" (0.50mm) and 0.024" (0.60mm) is acceptable within 0805 package specification

Substitute parts are grouped into two categories: direct equivalents matching the ±0.5% tolerance specification, and upgrade substitutes offering improved ±0.1% tolerance while maintaining all other critical parameters.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance):

RT0805DRD07300RL (YAGEO) is a direct electrical equivalent matching the RG2012P-301-D-T5 specification of 300 Ohms ±0.5% with identical power rating, package, composition, and temperature characteristics. This part is suitable for applications where AEC-Q200 automotive certification is not required. Inventory availability is 5,631 units.

Upgrade Substitutes (Improved Tolerance):

RG2012P-301-B-T5 (Susumu), ERA-6AEB301V (Panasonic Electronic Components), and RT0805BRD07300RL (YAGEO) all provide ±0.1% tolerance, representing a tighter tolerance specification than the main part. These upgrades maintain all other electrical and mechanical parameters. RG2012P-301-B-T5 and ERA-6AEB301V retain AEC-Q200 automotive certification. All three upgrade substitutes are active products with substantial inventory availability (29,797, 7,450, and 22,375 units respectively).

All substitute parts are ROHS3 compliant with MSL 1 rating, matching the environmental and regulatory status of the main part.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRD07300RL replace RG2012P-301-D-T5 in automotive applications?

A: RT0805DRD07300RL is electrically and mechanically equivalent to RG2012P-301-D-T5 with matching 300 Ohm ±0.5% specifications. However, RT0805DRD07300RL does not carry AEC-Q200 automotive certification. Use this part only in applications where AEC-Q200 certification is not a requirement.

Q: What is the difference between the main part and the upgrade substitutes?

A: The upgrade substitutes (RG2012P-301-B-T5, ERA-6AEB301V, RT0805BRD07300RL) offer ±0.1% tolerance compared to the main part's ±0.5% tolerance. All other electrical specifications, package dimensions, and operating parameters remain identical. Tighter tolerance provides improved circuit accuracy.

Q: Are all substitute parts compatible with the same PCB footprint?

A: Yes. All parts use the 0805 (2012 Metric) package with identical length and width dimensions (0.079" L x 0.049" W). Physical height variation between 0.020" and 0.024" is within standard 0805 package tolerance and does not affect PCB footprint compatibility.

Q: Which substitute part should be selected for maximum inventory availability?

A: RG2012P-301-B-T5 (Susumu) offers the highest inventory with 29,797 units in stock, followed by RT0805BRD07300RL (YAGEO) with 22,375 units.

Q: Do all substitute parts meet RoHS and REACH compliance requirements?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the environmental compliance status of the main part RG2012P-301-D-T5.

Q: Can ERA-6AEB301V be used as a direct replacement in automotive circuits?

A: ERA-6AEB301V is suitable for automotive applications as it carries AEC-Q200 certification and maintains all electrical specifications of the main part with improved ±0.1% tolerance. It is a qualified upgrade substitute for automotive use.
