Key Parameters

Substitute Part Grouping Explanation

Substitution of the RGH2012-2E-P-111-B is determined by strict adherence to the following parameters: resistance value (110 Ohms), 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 modifications:

Direct Equivalents (Identical Power Rating): Parts maintaining 0.25W power rating with identical electrical characteristics and package dimensions.

Upgraded Alternatives (Modified Power Rating): Parts with increased power dissipation capability (0.125W or 0.63W) while maintaining all other core electrical parameters and mechanical compatibility within the 0805 package envelope.

All substitute parts listed maintain the same resistance, tolerance, temperature coefficient, and operating temperature range as the main part. Variations in power rating, packaging format (Tape & Reel vs. bulk), and specific feature sets (automotive qualification, flame proof rating) are documented to enable informed selection based on application requirements.

Parameter Comparison

Engineering Selection Recommendations

RG2012P-111-B-T5 (Susumu): This part is the primary direct substitute from the original manufacturer. It maintains identical resistance, tolerance, temperature coefficient, and operating temperature specifications. The reduced power rating (0.125W vs. 0.25W) requires circuit analysis to confirm thermal margin adequacy. This part includes automotive AEC-Q200 qualification and anti-sulfur coating, providing enhanced reliability for demanding environments. Active product status ensures long-term availability. ROHS3 compliance is maintained.

2-2176091-8 (TE Connectivity Passive Product): This part provides exact electrical and power rating equivalence to the main part (0.25W). It is manufactured by TE Connectivity under the RP73P series (Holsworthy production line). Mechanical compatibility is confirmed with identical package format, though seated height is slightly increased (0.026" vs. 0.020"). Active product status and ROHS3 compliance are confirmed. REACH status is vendor undefined and requires clarification for regulated applications.

PHP00805E1100BST1 (Vishay Dale Thin Film): This part provides upgraded power dissipation capability (0.63W) within the same 0805 package envelope. Enhanced thermal performance is achieved through flame proof and moisture resistant construction. ROHS3 compliance is maintained. Increased seated height (0.033") requires PCB layout verification. Active product status ensures availability. This part is suitable for applications requiring higher power margin or thermal stress relief.

PHP00805E1100BBT1 (Vishay Dale Thin Film): This part is functionally identical to PHP00805E1100BST1 with upgraded power rating (0.63W) and enhanced safety features (flame proof, moisture resistant). RoHS non-compliance status disqualifies this part for regulated applications requiring ROHS3 certification. Increased seated height (0.033") requires PCB layout verification. Active product status is confirmed.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-111-B-T5 be used as a direct replacement for RGH2012-2E-P-111-B?

A: RG2012P-111-B-T5 maintains identical electrical specifications (110 Ohms ±0.1%, ±25ppm/°C, -55°C ~ 155°C operating range) and package format (0805). The power rating is reduced from 0.25W to 0.125W. Substitution is valid only if circuit thermal analysis confirms that the reduced power dissipation capability does not exceed application requirements. Mechanical compatibility is confirmed with identical seated height (0.020").

Q: What is the difference between the two Vishay PHP parts?

A: PHP00805E1100BST1 and PHP00805E1100BBT1 are electrically and mechanically identical. The primary distinction is RoHS compliance status: PHP00805E1100BST1 is ROHS3 compliant, while PHP00805E1100BBT1 is RoHS non-compliant. For applications subject to RoHS regulations, only PHP00805E1100BST1 is acceptable.

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 / 2.00mm x 1.25mm). However, seated height varies: RGH2012-2E-P-111-B and RG2012P-111-B-T5 are 0.020" (0.50mm), 2-2176091-8 is 0.026" (0.65mm), and both Vishay PHP parts are 0.033" (0.84mm). PCB layout clearance verification is required for parts with increased height.

Q: Which substitute part is recommended for automotive applications?

A: RG2012P-111-B-T5 includes automotive AEC-Q200 qualification and anti-sulfur coating, making it the specified choice for automotive environments. This part maintains active product status and ROHS3 compliance.

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

A: PHP00805E1100BST1 and PHP00805E1100BBT1 provide 0.63W power rating compared to the original 0.25W. Higher power rating does not negatively impact circuit performance; it provides additional thermal margin and stress relief. Mechanical compatibility requires verification of increased seated height (0.033" vs. 0.020").

Q: Is REACH compliance status critical for part selection?

A: REACH status should be evaluated based on application regulatory requirements. RGH2012-2E-P-111-B, RG2012P-111-B-T5, PHP00805E1100BST1, and PHP00805E1100BBT1 are all REACH Unaffected. Part 2-2176091-8 has vendor undefined REACH status and requires clarification from TE Connectivity for applications subject to REACH regulations.

Q: Can the obsolete RGH2012-2E-P-111-B be restocked?

A: The RGH2012-2E-P-111-B is classified as obsolete product status. Current inventory of 927 pieces is available, but long-term procurement is not assured. Migration to an active substitute part (RG2012P-111-B-T5, 2-2176091-8, or Vishay PHP series) is recommended for new designs and ongoing production requirements.
