Key Parameters

Substitute Part Grouping Explanation

Substitute parts are categorized based on electrical and mechanical compatibility with the original RGH2012-2E-P-151-B. The substitution criteria include: resistance value (150 Ohms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), operating temperature range (-55°C ~ 155°C), package size (0805/2012 Metric), and composition (Thin Film).

Direct Substitutes maintain identical or equivalent power ratings (0.125W to 0.25W) within the standard 0805 package thermal limits, matching all critical electrical parameters.

Upgrade Substitutes provide higher power ratings (0.63W, 5/8W) while maintaining identical electrical specifications, offering enhanced thermal performance and reliability margins for demanding applications.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Power Rating): The 4-2176091-1 from TE Connectivity provides identical power rating (0.25W, 1/4W) with Active product status and ROHS3 compliance, suitable for direct form-fit-function replacement in existing designs.

For Automotive and Anti-Sulfur Applications: The RG2012P-151-B-T5 features Anti-Sulfur protection and AEC-Q200 automotive qualification with Active status and ROHS3 compliance, appropriate for harsh environment applications despite lower power rating (0.125W, 1/8W).

For High Power Applications: The PHP00805E1500BST1 and PHP00805E1500BBT1 offer 0.63W (5/8W) power rating with Flame Proof, Moisture Resistant, and Safety features. The PHP00805E1500BST1 variant is ROHS3 Compliant, while PHP00805E1500BBT1 is RoHS non-compliant.

Compliance Considerations: All listed substitutes except PHP00805E1500BBT1 meet ROHS3 compliance requirements. All parts share MSL 1 (Unlimited) moisture sensitivity rating and ECCN EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting RGH2012-2E-P-151-B? A: The critical parameters are resistance value (150 Ohms), tolerance (±0.1%), temperature coefficient (±25ppm/°C), thin film composition, operating temperature range (-55°C ~ 155°C), and 0805 (2012 Metric) package size.

Q: Can I use a 0.125W resistor to replace a 0.25W resistor? A: The RG2012P-151-B-T5 offers 0.125W (1/8W) power rating in the same 0805 package. Substitution depends on the actual power dissipation in the circuit operating at or below 0.125W.

Q: What is the difference between Direct and Upgrade substitutes? A: Direct substitutes maintain equivalent power ratings (0.125W to 0.25W), while Upgrade substitutes provide higher power ratings (0.63W, 5/8W) with enhanced thermal performance.

Q: Are there height differences between the original and substitute parts? A: The original part height is 0.50mm. Direct substitutes range from 0.50mm to 0.65mm. Upgrade substitutes (PHP series) have 0.84mm height, requiring PCB clearance verification.

Q: Which substitute is appropriate for automotive applications? A: The RG2012P-151-B-T5 features AEC-Q200 automotive qualification and Anti-Sulfur protection with Active product status.

Q: What is the RoHS compliance status of the substitutes? A: The RGH2012-2E-P-151-B, RG2012P-151-B-T5, 4-2176091-1, and PHP00805E1500BST1 are ROHS3 Compliant. The PHP00805E1500BBT1 is RoHS non-compliant.
