Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-5492-B-T5 is determined by the following critical parameters:

Primary Matching Criteria:

• Resistance value: 54.9 kOhms
• Tolerance: ±0.1%
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• RoHS3 Compliance
• MSL Rating: 1 (Unlimited)

Secondary Compatibility Factors:

• Operating temperature range minimum: -55°C
• Power rating: Equal to or greater than 0.125W
• Number of terminations: 2
• Automotive qualification: AEC-Q200 (preferred for equivalent substitution)

Three substitute parts meet the core electrical and mechanical requirements. Substitutes are categorized by power rating variance and automotive qualification status. All candidates maintain identical resistance, tolerance, package geometry, and thermal characteristics. Differences exist in power dissipation capability and specific feature sets (anti-sulfur coating, moisture resistance).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred): ERA-6AEB5492V (Panasonic Electronic Components) is the primary equivalent substitute. This part matches all critical electrical parameters, maintains identical power rating (0.125W), operates within the same temperature range (-55°C ~ 155°C), and carries AEC-Q200 automotive qualification. The component is ROHS3 compliant with MSL 1 rating. Panasonic ERA-6A series availability is substantial (24392 units in stock), supporting supply chain reliability.

Higher Power Rating Alternatives: 7-2176093-0 (TE Connectivity Passive Product) and TNPW080554K9BEEN (Vishay Dale) provide increased power dissipation capability (0.25W and 0.26W respectively) while maintaining all other electrical specifications. These parts are suitable for applications where thermal margin is beneficial. TNPW080554K9BEEN additionally features anti-sulfur coating and moisture resistance, matching the feature set of the primary part. Both alternatives are AEC-Q200 rated and ROHS3 compliant.

Selection Criteria:

• For direct replacement in existing designs: ERA-6AEB5492V
• For applications requiring enhanced thermal performance: TNPW080554K9BEEN or 7-2176093-0
• For automotive applications with stringent environmental requirements: ERA-6AEB5492V or TNPW080554K9BEEN (both AEC-Q200 qualified with anti-sulfur features)

All substitute parts are active products with confirmed inventory availability and full compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB5492V be used as a direct replacement for RG2012P-5492-B-T5?

A: Yes. ERA-6AEB5492V is a direct equivalent. Both parts share identical resistance (54.9 kOhms), tolerance (±0.1%), power rating (0.125W), package (0805), composition (thin film), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C ~ 155°C). Both are AEC-Q200 qualified and ROHS3 compliant with MSL 1 rating.

Q: What is the difference between the 0.125W and 0.25W power-rated substitutes?

A: Power rating indicates maximum continuous power dissipation capability. The 0.125W parts (RG2012P-5492-B-T5 and ERA-6AEB5492V) are rated for lower power applications. The 0.25W part (7-2176093-0) and 0.26W part (TNPW080554K9BEEN) provide greater thermal headroom and can dissipate more power without exceeding temperature limits. Higher power-rated parts are suitable for applications with elevated current or thermal stress, though they occupy the same physical footprint (0805).

Q: Are all substitute parts automotive-qualified?

A: Three of four parts carry AEC-Q200 automotive qualification: RG2012P-5492-B-T5 (Susumu), ERA-6AEB5492V (Panasonic), and TNPW080554K9BEEN (Vishay Dale). The 7-2176093-0 (TE Connectivity) does not specify automotive qualification. For automotive applications, select from the three AEC-Q200 qualified options.

Q: What is the significance of anti-sulfur coating?

A: Anti-sulfur coating protects resistor terminations from sulfur-induced corrosion in harsh environments. RG2012P-5492-B-T5 and TNPW080554K9BEEN both feature anti-sulfur coating. ERA-6AEB5492V and 7-2176093-0 do not specify this feature. For applications in corrosive or high-humidity environments, anti-sulfur coated parts are preferred.

Q: Can these parts be used interchangeably in PCB designs?

A: All substitute parts use identical 0805 (2012 Metric) package with 2 terminations. PCB footprints are compatible. However, seated height varies slightly: RG2012P-5492-B-T5 (0.50mm), TNPW080554K9BEEN (0.55mm), ERA-6AEB5492V (0.60mm), and 7-2176093-0 (0.65mm). For designs with tight vertical clearance constraints, verify maximum height specifications against PCB assembly requirements.

Q: What is MSL 1 rating and why does it matter?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture bake-out requirements. All four parts carry MSL 1 rating, meaning they can be stored and handled under standard conditions without special moisture control procedures. This simplifies inventory management and reduces handling costs.

Q: Are all parts ROHS3 compliant?

A: Yes. All four parts—RG2012P-5492-B-T5, 7-2176093-0, ERA-6AEB5492V, and TNPW080554K9BEEN—are ROHS3 compliant, meeting EU Restriction of Hazardous Substances regulations.

Q: Which substitute offers the best inventory availability?

A: ERA-6AEB5492V (Panasonic) has the highest inventory level at 24392 units in stock, followed by 7-2176093-0 (TE Connectivity) with 2707 units. This makes ERA-6AEB5492V the most readily available substitute for urgent procurement needs.
