Part Overview

The RGH2012-2E-P-752-B is a 7.5 kOhms ±0.1% thin film chip resistor manufactured by Susumu in 0805 (2012 Metric) package format with 0.25W power rating. This component is classified as obsolete product status. Due to its obsolete designation, equivalent and substitute parts from active manufacturers are necessary to maintain design continuity and ensure long-term component availability for new production builds and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RGH2012-2E-P-752-B is determined by strict equivalence in the following parameters: resistance value (7.5 kOhms), tolerance (±0.1%), package format (0805 / 2012 Metric), composition (thin film), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C ~ 155°C).

Substitute parts are grouped into two categories based on power rating compatibility:

Direct Equivalents (Same Power Rating - 0.25W): Parts that maintain identical electrical specifications and power dissipation capacity. These provide one-to-one functional replacement without circuit redesign.

Upgraded Alternatives (Higher Power Rating - 0.63W or 0.125W): Parts that share all core electrical parameters but differ in power handling capability. Upgraded alternatives with higher power ratings (0.63W) provide enhanced thermal margin and are suitable for applications requiring increased power dissipation headroom. Downgraded alternatives with lower power ratings (0.125W) are suitable only for applications with reduced power requirements.

All substitute candidates maintain compliance with RoHS3 and MSL 1 specifications, ensuring compatibility with modern manufacturing and storage requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Specifications):

The 9-2176092-3 manufactured by TE Connectivity Passive Product is the primary direct equivalent. This part maintains identical resistance (7.5 kOhms), tolerance (±0.1%), power rating (0.25W), and all electrical parameters of the RGH2012-2E-P-752-B. The part is active product status with ROHS3 compliance. The 0.026" seated height is marginally higher than the original specification but remains within typical PCB assembly tolerances for 0805 packages. This part is suitable for applications requiring exact electrical and thermal performance matching.

For Automotive and Anti-Sulfur Applications:

The RG2012P-752-B-T5 manufactured by Susumu is an active product from the same manufacturer as the original part. This substitute features automotive AEC-Q200 qualification and anti-sulfur composition, providing enhanced reliability in harsh environments. The power rating is reduced to 0.125W (1/8W), making this part suitable only for applications with lower power dissipation requirements. The seated height matches the original specification at 0.020" (0.50mm).

For Enhanced Thermal Performance:

The PHP00805E7501BST1 manufactured by Vishay Dale Thin Film provides upgraded power rating of 0.63W (5/8W) with flame proof and moisture resistant features. This part is ROHS3 compliant and active product status. The increased power rating provides thermal margin for applications with higher power dissipation. The seated height is 0.033" (0.84mm), which may require PCB layout verification for space-constrained designs. This part is supplied in Cut Tape (CT) packaging format.

Avoid:

The PHP00805E7501BBT1 is RoHS non-compliant and should not be selected for applications requiring RoHS3 compliance or modern manufacturing standards.

Frequently Asked Questions (FAQ)

Q: Can the RG2012P-752-B-T5 be used as a direct replacement for the RGH2012-2E-P-752-B?

A: The RG2012P-752-B-T5 shares identical resistance, tolerance, package, and temperature specifications. However, the power rating is reduced from 0.25W to 0.125W. This part is suitable only if the application circuit dissipates 0.125W or less across the resistor. For applications requiring the full 0.25W rating, this part is not appropriate.

Q: What is the difference between the PHP00805E7501BBT1 and PHP00805E7501BST1?

A: Both parts are manufactured by Vishay Dale Thin Film with identical electrical specifications (7.5 kOhms, ±0.1%, 0.63W). The primary difference is packaging format: PHP00805E7501BBT1 is supplied in Tape & Reel (TR) format, while PHP00805E7501BST1 is supplied in Cut Tape (CT) format. Additionally, PHP00805E7501BBT1 is RoHS non-compliant, whereas PHP00805E7501BST1 is ROHS3 compliant. For new designs, PHP00805E7501BST1 is the preferred selection.

Q: Are all substitute parts compatible with the original PCB layout?

A: All substitute parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). However, seated heights vary: the original and RG2012P-752-B-T5 are 0.020" (0.50mm), the 9-2176092-3 is 0.026" (0.65mm), and the Vishay parts are 0.033" (0.84mm). For space-constrained designs with tight component clearances, verify that the increased height does not interfere with adjacent components or conformal coating processes.

Q: Which substitute part is recommended for new production designs?

A: For new production designs requiring exact electrical and thermal performance matching, the 9-2176092-3 from TE Connectivity is the primary recommendation due to active product status, ROHS3 compliance, and identical power rating. For applications requiring enhanced thermal margin, the PHP00805E7501BST1 from Vishay Dale provides upgraded power rating with ROHS3 compliance and active product status.

Q: What is the significance of the ±25ppm/°C temperature coefficient?

A: The temperature coefficient of ±25ppm/°C indicates the maximum change in resistance value per degree Celsius across the operating temperature range. All substitute parts maintain this specification, ensuring equivalent temperature stability and drift characteristics across the -55°C to 155°C operating range.

Q: Are there packaging format considerations for high-volume production?

A: Yes. The RGH2012-2E-P-752-B is supplied in bulk packaging. For high-volume production, Tape & Reel (TR) format is standard and more efficient for automated assembly. The 9-2176092-3, RG2012P-752-B-T5, and PHP00805E7501BBT1 are available in TR format. The PHP00805E7501BST1 is supplied in Cut Tape (CT) format, which is suitable for lower-volume or mixed-component assembly operations.
