Key Parameters

Substitute Part Grouping Explanation

Substitution of the RGH2012-2E-P-751-B is determined by strict equivalence in the following parameters: resistance value (750 Ohms), tolerance (±0.1%), package format (0805 / 2012 Metric), composition (thin film), temperature coefficient (±25ppm/°C), and operating temperature range (-55°C ~ 155°C). The 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, ensuring drop-in replacement capability without circuit redesign.

Upgrade Options (Higher Power Rating - 0.63W): Parts that exceed the original power specification, providing enhanced thermal performance and safety margins while maintaining all other electrical parameters.

Downgrade Option (Lower Power Rating - 0.125W): Parts that reduce power specification but maintain electrical performance for applications with reduced thermal requirements.

Engineering Selection Recommendations

RP73PF2A750RBTDF (Direct Equivalent - Recommended Primary Substitute)

The RP73PF2A750RBTDF from TE Connectivity Passive Product provides direct electrical and mechanical equivalence to the RGH2012-2E-P-751-B with identical 0.25W power rating, 750 Ohm resistance, ±0.1% tolerance, and 0805 package format. This part maintains active product status with ROHS3 compliance. The maximum seated height of 0.026" (0.65mm) represents a minor increase from the original 0.020" (0.50mm) but remains within standard PCB assembly tolerances for 0805 components. This part is suitable for direct replacement in applications requiring equivalent thermal and electrical performance.

RG2012P-751-B-T5 (Downgrade Option - Power Reduction)

The RG2012P-751-B-T5 from Susumu offers the same manufacturer lineage as the original part with identical electrical specifications but reduced power rating of 0.125W (1/8W). This part includes automotive AEC-Q200 qualification and anti-sulfur features, providing enhanced reliability in harsh environments. The seated height remains at 0.020" (0.50mm), matching the original dimensions. This substitute is applicable only to applications where power dissipation does not exceed 0.125W, as the reduced power rating limits thermal capacity.

PHP00805E7500BST1 (Upgrade Option - Enhanced Safety)

The PHP00805E7500BST1 from Vishay Dale Thin Film provides upgraded specifications with 0.63W (5/8W) power rating, flame proof and moisture resistant construction, and safety-rated design. This part maintains ROHS3 compliance and all electrical parameters identical to the original. The increased seated height of 0.033" (0.84mm) requires verification of PCB assembly clearances. This upgrade is suitable for applications requiring enhanced thermal margin, flame resistance, and safety certifications.

PHP00805E7500BBT1 (Upgrade Option - Alternative Packaging)

The PHP00805E7500BBT1 from Vishay Dale Thin Film provides identical specifications to the PHP00805E7500BST1 with equivalent 0.63W power rating and safety features. This part is RoHS non-compliant and should be selected only when RoHS3 compliance is not a design requirement. The increased seated height of 0.033" (0.84mm) requires PCB assembly clearance verification.

Frequently Asked Questions (FAQ)

Q: Can the RG2012P-751-B-T5 be used as a direct replacement for the RGH2012-2E-P-751-B?

A: The RG2012P-751-B-T5 maintains identical electrical specifications (750 Ohms, ±0.1%, ±25ppm/°C, -55°C ~ 155°C) and package format (0805). However, the power rating is reduced from 0.25W to 0.125W. This part is suitable only if circuit power dissipation does not exceed 0.125W. Exceeding this power rating will result in component failure.

Q: What is the primary advantage of the RP73PF2A750RBTDF substitute?

A: The RP73PF2A750RBTDF provides direct electrical and thermal equivalence with identical 0.25W power rating, maintaining the same thermal performance as the original RGH2012-2E-P-751-B. This part is manufactured by TE Connectivity Passive Product with active product status and ROHS3 compliance, ensuring long-term availability and regulatory compliance.

Q: Are the PHP00805E7500BBT1 and PHP00805E7500BST1 interchangeable?

A: Both parts are electrically and mechanically identical with 0.63W power rating, flame proof construction, and moisture resistant features. The primary difference is RoHS compliance status: PHP00805E7500BST1 is ROHS3 compliant while PHP00805E7500BBT1 is RoHS non-compliant. Selection depends on regulatory requirements for the end application.

Q: Does the increased seated height of substitute parts affect PCB assembly?

A: The original RGH2012-2E-P-751-B has a maximum seated height of 0.020" (0.50mm). The RP73PF2A750RBTDF increases to 0.026" (0.65mm), while the Vishay PHP series reaches 0.033" (0.84mm). These height differences remain within standard 0805 component tolerances but require verification of PCB assembly clearances, particularly in high-density layouts or applications with height restrictions.

Q: Which substitute part is recommended for automotive applications?

A: The RG2012P-751-B-T5 includes automotive AEC-Q200 qualification with anti-sulfur features, making it suitable for automotive environments. However, this part has reduced power rating (0.125W). For automotive applications requiring full 0.25W power rating, the RP73PF2A750RBTDF is the appropriate selection, though it does not carry explicit automotive certification.

Q: What is the impact of selecting a higher power-rated substitute?

A: Selecting the PHP00805E7500BST1 or PHP00805E7500BBT1 (0.63W rating) instead of the original 0.25W part provides increased thermal margin and safety performance. The component will operate at lower junction temperature under identical power dissipation conditions. This upgrade is beneficial for reliability-critical applications but does not alter electrical performance or circuit behavior.

Q: Are all substitute parts RoHS3 compliant?

A: Four of the five substitute parts are ROHS3 compliant: RG2012P-751-B-T5, RP73PF2A750RBTDF, and PHP00805E7500BST1. The PHP00805E7500BBT1 is RoHS non-compliant. Design requirements for regulatory compliance must determine part selection accordingly.
