RG2012P-5232-C-T5 Equivalent & Substitute Parts

Part Overview

The RG2012P-5232-C-T5 is a 52.3 kOhms ±0.25% thin film chip resistor in 0805 (2012 Metric) package rated for 0.125W (1/8W) power dissipation. Manufactured by Susumu, this component features anti-sulfur construction and automotive AEC-Q200 qualification, suitable for high-reliability applications across -55°C to 155°C operating temperature range. The part is currently obsolete, necessitating identification of functionally equivalent alternatives from active product lines that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Compatibility Parameters:

Resistance value: 52.3 kOhms (exact match required)
Package type: 0805 (2012 Metric) (exact match required)
Power rating: 0.125W minimum (equal or higher acceptable)
Composition: Thin Film (exact match required)
Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)

Tolerance Considerations: Substitute parts with equal or tighter tolerance (lower percentage value) are electrically compatible. The original part specifies ±0.25% tolerance; substitutes with ±0.1% or ±0.05% tolerance provide improved precision while maintaining functional compatibility.

Automotive Qualification: The original part carries AEC-Q200 automotive qualification. Substitute parts are grouped into two categories: those maintaining AEC-Q200 qualification and those without automotive-specific certification. Selection depends on application requirements.

Temperature Coefficient: The original part specifies ±25ppm/°C. Substitute parts with equal or lower temperature coefficient values (±10ppm/°C, ±15ppm/°C) provide improved thermal stability while remaining compatible.

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series - Automotive AEC-Q200):

The Susumu RG2012N-5232-B-T5 and RG2012P-5232-B-T5 are direct functional replacements maintaining identical package, power rating, and operating temperature range. Both are active products with AEC-Q200 automotive qualification. The RG2012N-5232-B-T5 offers improved tolerance (±0.1%) and lower temperature coefficient (±10ppm/°C) compared to the original ±0.25% tolerance specification. The RG2012P-5232-B-T5 maintains the original ±25ppm/°C temperature coefficient while improving tolerance to ±0.1%.

For applications requiring maximum precision, the RG2012N-5232-W-T1 and RG2012P-5232-W-T5 provide ±0.05% tolerance with identical electrical and mechanical compatibility.

Secondary Substitutes (Multi-Manufacturer - Automotive AEC-Q200):

The Panasonic ERA-6AEB5232V is an active product with AEC-Q200 automotive qualification, ±0.1% tolerance, and identical package and power specifications. This part provides an alternative source from a major automotive-qualified supplier.

Tertiary Substitutes (Multi-Manufacturer - Non-Automotive):

The YAGEO RT0805CRD0752K3L matches the original ±0.25% tolerance specification and is available as an active product. The YAGEO RT0805BRD0752K3L provides ±0.1% tolerance. Both parts lack automotive AEC-Q200 qualification.

The TE Connectivity 6-2176093-8 provides higher power rating (0.25W) with ±0.1% tolerance but lacks automotive qualification. The TE Connectivity RP73D2A52K3BTDF offers ±0.1% tolerance and improved temperature coefficient (±15ppm/°C) without automotive qualification.

The Vishay MCU08050D5232BP500 provides ±0.1% tolerance with anti-sulfur construction but operates to 125°C maximum, limiting its use in applications requiring the full -55°C to 155°C range.

Selection Criteria:

For automotive applications requiring AEC-Q200 compliance, select from Susumu RG series (RG2012N-5232-B-T5, RG2012P-5232-B-T5, RG2012N-5232-W-T1, RG2012P-5232-W-T5) or Panasonic ERA-6AEB5232V. For non-automotive applications, YAGEO and TE Connectivity alternatives provide equivalent electrical performance with active product status and established supply chains.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with tighter tolerance than the original RG2012P-5232-C-T5?

A: Yes. The original part specifies ±0.25% tolerance. Substitute parts with ±0.1% or ±0.05% tolerance are electrically compatible and provide improved precision. Tighter tolerance does not create incompatibility; it only enhances circuit performance where precision is beneficial.

Q: Is the 0805 package dimension identical across all substitute parts?

A: Yes. All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical mounting compatibility is maintained across all listed substitutes. Height variations (0.020" to 0.026" seated maximum) are within standard PCB assembly tolerances and do not affect placement or soldering.

Q: What is the difference between Susumu RG2012N and RG2012P series?

A: Both series are 52.3 kOhms thin film resistors in 0805 package with AEC-Q200 qualification. The RG2012N series features lower temperature coefficient (±10ppm/°C) compared to RG2012P (±25ppm/°C). The RG2012N series is recommended for applications requiring superior thermal stability. Both series are available with multiple tolerance grades (±0.05%, ±0.1%).

Q: Does the original part's anti-sulfur feature affect substitute selection?

A: The original RG2012P-5232-C-T5 includes anti-sulfur construction. Among active substitutes, the Susumu RG series maintains this feature. The Panasonic ERA-6AEB5232V and Vishay MCU08050D5232BP500 also include anti-sulfur construction. YAGEO and TE Connectivity RP73 series do not specify anti-sulfur features. For applications in sulfur-prone environments, prioritize substitutes with documented anti-sulfur construction.

Q: Can I substitute the RG2012P-5232-C-T5 with the TE Connectivity 6-2176093-8 which has higher power rating?

A: Yes, electrically and mechanically. The 6-2176093-8 provides 0.25W (1/4W) power rating compared to the original 0.125W (1/8W). Higher power rating does not create incompatibility; it only provides additional thermal margin. However, this part lacks AEC-Q200 automotive qualification. Use this substitute only in non-automotive applications or where automotive qualification is not required.

Q: Why does the Vishay MCU08050D5232BP500 have a lower maximum operating temperature?

A: The Vishay MCU08050D5232BP500 specifies -55°C to 125°C operating range, compared to the original -55°C to 155°C. This part is not suitable for applications requiring operation above 125°C. For full temperature range compatibility, select substitutes specifying -55°C to 155°C operating range.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitute parts are RoHS3 compliant and carry REACH Unaffected or Vendor Undefined status, matching the original part's environmental compliance profile.

Q: What is the inventory status of substitute parts?

A: All substitute parts listed are available as new original stock. Susumu RG2012P-5232-B-T5 has the highest inventory (6018 pcs), followed by Panasonic ERA-6AEB5232V (19116 pcs). Inventory levels are subject to change and should be verified at time of procurement.
